Cryptography news and discussions

Cryptography is the art of creating mathematical assurances for who can do what with data, including but not limited to encryption of messages such that only the key-holder can read it. Cryptography lives at an intersection of math and computer science. This subreddit covers the theory and practice of modern and *strong* cryptography, and it is a technical subreddit focused on the algorithms and implementations of cryptography.

Ultimate glossary of crypto currency terms, acronyms and abbreviations

I thought it would be really cool to have an ultimate guide for those new to crypto currencies and the terms used. I made this mostly for beginner’s and veterans alike. I’m not sure how much use you will get out of this. Stuff gets lost on Reddit quite easily so I hope this finds its way to you. Included in this list, I have included most of the terms used in crypto-communities. I have compiled this list from a multitude of sources. The list is in alphabetical order and may include some words/terms not exclusive to the crypto world but may be helpful regardless.
2FA
Two factor authentication. I highly advise that you use it.
51% Attack:
A situation where a single malicious individual or group gains control of more than half of a cryptocurrency network’s computing power. Theoretically, it could allow perpetrators to manipulate the system and spend the same coin multiple times, stop other users from completing blocks and make conflicting transactions to a chain that could harm the network.
Address (or Addy):
A unique string of numbers and letters (both upper and lower case) used to send, receive or store cryptocurrency on the network. It is also the public key in a pair of keys needed to sign a digital transaction. Addresses can be shared publicly as a text or in the form of a scannable QR code. They differ between cryptocurrencies. You can’t send Bitcoin to an Ethereum address, for example.
Altcoin (alternative coin): Any digital currency other than Bitcoin. These other currencies are alternatives to Bitcoin regarding features and functionalities (e.g. faster confirmation time, lower price, improved mining algorithm, higher total coin supply). There are hundreds of altcoins, including Ether, Ripple, Litecoin and many many others.
AIRDROP:
An event where the investors/participants are able to receive free tokens or coins into their digital wallet.
AML: Defines Anti-Money Laundering laws**.**
ARBITRAGE:
Getting risk-free profits by trading (simultaneous buying and selling of the cryptocurrency) on two different exchanges which have different prices for the same asset.
Ashdraked:
Being Ashdraked is essentially a more detailed version of being Zhoutonged. It is when you lose all of your invested capital, but you do so specifically by shorting Bitcoin. The expression “Ashdraked” comes from a story of a Romanian cryptocurrency investor who insisted upon shorting BTC, as he had done so successfully in the past. When the price of BTC rose from USD 300 to USD 500, the Romanian investor lost all of his money.
ATH (All Time High):
The highest price ever achieved by a cryptocurrency in its entire history. Alternatively, ATL is all time low
Bearish:
A tendency of prices to fall; a pessimistic expectation that the value of a coin is going to drop.
Bear trap:
A manipulation of a stock or commodity by investors.
Bitcoin:
The very first, and the highest ever valued, mass-market open source and decentralized cryptocurrency and digital payment system that runs on a worldwide peer to peer network. It operates independently of any centralized authorities
Bitconnect:
One of the biggest scams in the crypto world. it was made popular in the meme world by screaming idiot Carlos Matos, who infamously proclaimed," hey hey heeeey” and “what's a what's a what's up wasssssssssuuuuuuuuuuuuup, BitConneeeeeeeeeeeeeeeeeeeeeeeect!”. He is now in the mentally ill meme hall of fame.
Block:
A package of permanently recorded data about transactions occurring every time period (typically about 10 minutes) on the blockchain network. Once a record has been completed and verified, it goes into a blockchain and gives way to the next block. Each block also contains a complex mathematical puzzle with a unique answer, without which new blocks can’t be added to the chain.
Blockchain:
An unchangeable digital record of all transactions ever made in a particular cryptocurrency and shared across thousands of computers worldwide. It has no central authority governing it. Records, or blocks, are chained to each other using a cryptographic signature. They are stored publicly and chronologically, from the genesis block to the latest block, hence the term blockchain. Anyone can have access to the database and yet it remains incredibly difficult to hack.
Bullish:
A tendency of prices to rise; an optimistic expectation that a specific cryptocurrency will do well and its value is going to increase.
BTFD:
Buy the fucking dip. This advise was bestowed upon us by the gods themselves. It is the iron code to crypto enthusiasts.
Bull market:
A market that Cryptos are going up.
Consensus:
An agreement among blockchain participants on the validity of data. Consensus is reached when the majority of nodes on the network verify that the transaction is 100% valid.
Crypto bubble:
The instability of cryptocurrencies in terms of price value
Cryptocurrency:
A type of digital currency, secured by strong computer code (cryptography), that operates independently of any middlemen or central authoritie
Cryptography:
The art of converting sensitive data into a format unreadable for unauthorized users, which when decoded would result in a meaningful statement.
Cryptojacking:
The use of someone else’s device and profiting from its computational power to mine cryptocurrency without their knowledge and consent.
Crypto-Valhalla:
When HODLers(holders) eventually cash out they go to a place called crypto-Valhalla. The strong will be separated from the weak and the strong will then be given lambos.
DAO:
Decentralized Autonomous Organizations. It defines A blockchain technology inspired organization or corporation that exists and operates without human intervention.
Dapp (decentralized application):
An open-source application that runs and stores its data on a blockchain network (instead of a central server) to prevent a single failure point. This software is not controlled by the single body – information comes from people providing other people with data or computing power.
Decentralized:
A system with no fundamental control authority that governs the network. Instead, it is jointly managed by all users to the system.
Desktop wallet:
A wallet that stores the private keys on your computer, which allow the spending and management of your bitcoins.
DILDO:
Long red or green candles. This is a crypto signal that tells you that it is not favorable to trade at the moment. Found on candlestick charts.
Digital Signature:
An encrypted digital code attached to an electronic document to prove that the sender is who they say they are and confirm that a transaction is valid and should be accepted by the network.
Double Spending:
An attack on the blockchain where a malicious user manipulates the network by sending digital money to two different recipients at exactly the same time.
DYOR:
Means do your own research.
Encryption:
Converting data into code to protect it from unauthorized access, so that only the intended recipient(s) can decode it.
Eskrow:
the practice of having a third party act as an intermediary in a transaction. This third party holds the funds on and sends them off when the transaction is completed.
Ethereum:
Ethereum is an open source, public, blockchain-based platform that runs smart contracts and allows you to build dapps on it. Ethereum is fueled by the cryptocurrency Ether.
Exchange:
A platform (centralized or decentralized) for exchanging (trading) different forms of cryptocurrencies. These exchanges allow you to exchange cryptos for local currency. Some popular exchanges are Coinbase, Bittrex, Kraken and more.
Faucet:
A website which gives away free cryptocurrencies.
Fiat money:
Fiat currency is legal tender whose value is backed by the government that issued it, such as the US dollar or UK pound.
Fork:
A split in the blockchain, resulting in two separate branches, an original and a new alternate version of the cryptocurrency. As a single blockchain forks into two, they will both run simultaneously on different parts of the network. For example, Bitcoin Cash is a Bitcoin fork.
FOMO:
Fear of missing out.
Frictionless:
A system is frictionless when there are zero transaction costs or trading retraints.
FUD:
Fear, Uncertainty and Doubt regarding the crypto market.
Gas:
A fee paid to run transactions, dapps and smart contracts on Ethereum.
Halving:
A 50% decrease in block reward after the mining of a pre-specified number of blocks. Every 4 years, the “reward” for successfully mining a block of bitcoin is reduced by half. This is referred to as “Halving”.
Hardware wallet:
Physical wallet devices that can securely store cryptocurrency maximally. Some examples are Ledger Nano S**,** Digital Bitbox and more**.**
Hash:
The process that takes input data of varying sizes, performs an operation on it and converts it into a fixed size output. It cannot be reversed.
Hashing:
The process by which you mine bitcoin or similar cryptocurrency, by trying to solve the mathematical problem within it, using cryptographic hash functions.

Lambo:
This stands for Lamborghini. A small meme within the investing community where the moment someone gets rich they spend their earnings on a lambo. One day we will all have lambos in crypto-valhalla.
Ledger:
Away from Blockchain, it is a book of financial transactions and balances. In the world of crypto, the blockchain functions as a ledger. A digital currency’s ledger records all transactions which took place on a certain block chain network.
Leverage:
Trading with borrowed capital (margin) in order to increase the potential return of an investment.

Pre mining:
The mining of a cryptocurrency by its developers before it is released to the public.
Proof of stake (POS):
A consensus distribution algorithm which essentially rewards you based upon the amount of the coin that you own. In other words, more investment in the coin will leads to more gain when you mine with this protocol In Proof of Stake, the resource held by the “miner” is their stake in the currency.
PROOF OF WORK (POW) :
The competition of computers competing to solve a tough crypto math problem. The first computer that does this is allowed to create new blocks and record information.” The miner is then usually rewarded via transaction fees.
Protocol:
A standardized set of rules for formatting and processing data.
Public key / private key:
A cryptographic code that allows a user to receive cryptocurrencies into an account. The public key is made available to everyone via a publicly accessible directory, and the private key remains confidential to its respective owner. Because the key pair is mathematically related, whatever is encrypted with a public key may only be decrypted by its corresponding private key.

Recovery phrase:
A set of phrases you are given whereby you can regain or access your wallet should you lose the private key to your wallets — paper, mobile, desktop, and hardware wallet. These phrases are some random 12–24 words. A recovery Phrase can also be called as Recovery seed, Seed Key, Recovery Key, or Seed Phrase.

“Funds are safe."
“the exchage I use got hacked!”“Oh no, are your funds safu?”
“My coins better be safu!”


Sats/Satoshi:
The smallest fraction of a bitcoin is called a “satoshi” or “sat”. It represents one hundred-millionth of a bitcoin and is named after Satoshi Nakamoto.
Satoshi Nakamoto:
This was the pseudonym for the mysterious creator of Bitcoin.
Scalability:
The ability of a cryptocurrency to contain the massive use of its Blockchain.
Sharding:
A scaling solution for the Blockchain. It is generally a method that allows nodes to have partial copies of the complete blockchain in order to increase overall network performance and consensus speeds.

Surge:
When a crypto currency appreciates or goes up in price.
Tank:
The opposite of mooning. When a coin tanks it can also be described as crashing.
Tendies
For traders , the chief prize is “tendies” (chicken tenders, the treat an overgrown man-child receives for being a “Good Boy”) .
Token:
A unit of value that represents a digital asset built on a blockchain system. A token is usually considered as a “coin” of a cryptocurrency, but it really has a wider functionality.
TOR: “The Onion Router” is a free web browser designed to protect users’ anonymity and resist censorship. Tor is usually used surfing the web anonymously and access sites on the “Darkweb”.
Transaction fee:
An amount of money users are charged from their transaction when sending cryptocurrencies.
Volatility:
A measure of fluctuations in the price of a financial instrument over time. High volatility in bitcoin is seen as risky since its shifting value discourages people from spending or accepting it.
Wallet:
A file that stores all your private keys and communicates with the blockchain to perform transactions. It allows you to send and receive bitcoins securely as well as view your balance and transaction history.
Whale:
An investor that holds a tremendous amount of cryptocurrency. Their extraordinary large holdings allow them to control prices and manipulate the market.
Whitepaper:

A comprehensive report or guide made to understand an issue or help decision making.

Rough days transcript: the best is yet to come, kill the old system, BUIDL time, we live in a DeFi bubble, power to the edges, voting challenge and rembeber you're in control kids!

Hi everybody, Charles Hoskinson here, live from warm sunny Colorado! Always warm, always sunny, sometimes Colorado. I got my Massey Ferguson hat on. Take that off, see, my hair's all messed up. One of these days and we'll lose all that hair.
It's a rough day today and that markets are terrible down 20 percent for most people and every now and then I talk about price. I rarely do but in general let's talk about the macro. You know crypto is a unique phenomenon. It's a unique thing and these are crazy times. I remember just a few months back when coronavirus first came out and we saw basically everything just bottom out everybody went crazy. They went to cash all asset classes. Just went to hell in a handbasket and I did a video and I said guys our best days are ahead of us as an ecosystem and as an industry and what happened everything got better over time. People started getting more optimistic. You know the reality is that we are seeing an old industry die right now, the legacy financial system.
I just read Biden's tax plan. He wants to treat capital gains as ordinary income and put another 12 and a half percent on top of that. All this stuff and at the end of the day all these new taxes amount to a trillion or so extra dollars I think per year in income... Takes six years to the make back what they printed out of thin air for coronavirus and are willing to print again which begs the question why do we even pay taxes anymore if we can just print money out of thin air? We have a whole movement of people: the AOC crowd wake up every day and they say modern monetary theory, the actual supply, doesn't matter. All that matters is how much can we print and get away with it. This is where we're at as an economy right now and globally speaking a lot of other nations agree with this. So, given that the whole world, the leadership of the world, talking about negative interest rates, they're talking about predatory financial systems hyperinflation. Just print money, modern monetary theory, just print as much cash as you want and we look to the cryptocurrency industry, and god, we got a lot of problems...
I think this (week's market) collapse is probably because one of the most prominent exchanges in South Korea got hit. They got shut down by the South Korean government and they at one time were responsible for a big part of the Kimchi premium and you know what? Korean government might shut down a few more Korean exchanges and usually the market based these things in. We got crazy yield farming weird stuff going on in the DeFi space. All these other local events and their blips they don't really matter that much just like corona in the long term won't matter too much in terms of the markets. What matters is the trend and where are we going. I had a meeting with some people this morning and we talked about revolutionizing the healthcare industry and getting things better in terms of supply chains. I had another meeting with a soon-to-be former Wyoming state representative about how we're going to get governments to adopt blockchain technology. I talk every day to governors, heads of state, congressmen, senators, mayors. Some cities, sometimes very large cities, with millions of people and they all say the same thing. We need help, we need solutions, we're damn tired of the way that the old system is running. You know what? if we don't solve it a lot of people are going to get hurt or continue to be hurt.
The common theme that we all have is no one's happy. Look at the black-lives-matter protests, taking their philosophy of the organization aside, the rank and file people are there not because they love Marxism. They're there because they're unhappy with the way society is and why shouldn't they be? When my grandfather, got his first job, on my mom's side, out of the Korean war, he was a lineman and he made enough money from that job to have seven kids and have his wife stay at home. No college degree, fresh out of high school, fresh out of marine demolitions and a lineman. Five boys and two girls and he could take care of that family and save money every month. Have a car and a house and that was his standard of living. How many people in the middle class today in the United States or Europe for that matter have the ability on a single person's salary to raise seven children and have the wife or the husband stay at home? How many people, not many, why? because our monetary system has failed us. The inflationary policy has created a situation where the Jeff Bezos can have 200 billion dollars and make windfall profits every year regardless of how bad the economy is. The everyday people they don't get a pay increase, so in a lot of cases they don't get to keep their job and their money deteriorates in value a lot more than three percent per year.
Our industry has principles in that we worship the math and the protocols and the stable monetary policy. These types of things, and as corrupt as some of the exchanges can be, and some of the bad actors are, all movements suffer from these warts, and they're finite and temporary. You run out of them. At some point self-regulation kicks in or standards kick in and these bad actors flush out and what's left behind is a crucible that contains the truth of the matter which is: we're going to win as an industry. There's just no doubt in my mind. You have bad days in the market, you have damn good days in the market, you get addicted to the good ones and you hate the bad ones but at the end of the day it's only going in one direction which is crypto is going to eat the world: every voting system, every property registration system, every monetary system, the next 25 to 50 years is going to be running on the tech we build and others build and running with the principles of power to the edges.
This is the great challenge of our time. To do it in a way that it's fair, transparent, open and doesn't allow a government to co-opt it. It's gonna be a lot of fights here. The least of our concerns and matters are a red day and every now and then I like making these videos to remind people why I'm here and why you should be here too. As toxic as the trolls could be and these other people can be, none of them really matter. Markets don't really matter, what matters are the principles and the purpose behind what we do and you have to ask yourself are you happy with the way that society is? Are you happy with the money in your pocket? Are you happy with the political leadership representing your nations? Are you happy with your future and do you honestly believe if we keep doing the things that we did and continue to do that the future is going to be better or do you think it's going to be worse or stagnant?
I think too many people have woken up and they realize that if we continue doing the things that we do the future is going to be a bad place and they don't want that to happen. We're voting with our wallets, we're voting with our feet and we as a collective industry are waking up and figuring out how to build something better and there's some good days and bad days along the way. Today's a bad one but there are going to be good days tomorrow just like I told you back when corona made everything go into free fall and I told you before and I warned you about with ICO mania.
We're in a DeFi bubble right now, there's no doubt in my mind about that. I saw it in 2017 with ICO mania. I see it here and there's probably going to be worse days ahead in that respect but the trend is always the same and never forget that and never forget that real people are actually adopting these systems and using them. Every day we see more and more and every day that movement grows and what's so humbling is that I know a lot of you are here with me. It used to be pretty lonely space to be in a few years back. You know, the conferences, they didn't have many people. My first bitcoin meetup group in 2011 in Colorado is at the gypsy house cafe I think, in Denver. I registered for the event I showed up. Two people registered myself and another guy and the other guy didn't show up so I had coffee with myself. Compare that with the Shelley summit that we had in July of 2020. 10 000 attendees, 10 000 from all across the world, compare that to where we are at today just nine years later pretty amazing if you think about how fast things have grown and how many fertile beautiful ideas exist in this industry and what this industry is doing for the world as a whole.
That is why we're going to win because at the end of day who can argue against freedom? Who can argue against liberty? Who can argue against putting people in control? The only way you can is when you believe people are stupid, people are evil, people are incapable and I suppose that's a philosophical difference between those who currently lead and the people who want to replace them. The people in charge right now of the world, the big banks, the fortune 500 companies, the media, Hollywood... These things, they're very cynical, people who believe in the worst in us they look at everyday people who sustain and disgust and say these people if left to their own devices will be chaos. These people, if left to govern themselves will burn everything to the ground and destroy everything and every single time I have ever seen a bad event happen what the news doesn't show you and what those people don't talk about is how we come together and help each other out. Someone gets injured in the streets more often than not people show up and help them, people need a helping hand. Someone always shows up more often than not and this is no different. I don't believe the political process is effective anymore in any modern democracy. They've all been co-opted, perhaps they always were but what I do believe is that we can come together and change things economically which is what we're doing.
It's messy building our own money, it is messy building our own industry, it is messy. We make a lot of mistakes along the way. We lose a lot along the way, we collect some scars too while we're at it but progress every year keeps being made. The technology every year keeps getting better. Today, right here right now, provably secure proof of stake protocols are in circulation. They were a fantasy five years ago now they're a fact of life today. Right here right now snarks have evolved by an order of magnitude in every category from validation time to efficiency to proof size in all favorable ways which opens up all kinds of new applications and scalability and privacy. Today, right here right now, layer 2 protocols are more advanced than they have ever been in our industry's history giving us the ability to build payment systems that scale to billions of people. Today, right here right now, we are seeing massive innovations in governance and a fertile environment for things like approval voting, threshold voting, preference voting, quadratic voting, that will enable us to build all kinds of new treasuries and governance systems that eventually will scale to nation states.
As the politicians of today argue whether the post office can properly count paper ballots that people mail we are building voting systems with state-of-the-art cryptography living on phones where you can vote. It's just a tap of a button and enjoy more security than we have ever imagined before. That is the future this movement, is enabling humanity money flowing at the speed of thought and the speed of thought making new money. How can you compete with that? You can't unless you bring people down with cynicism and disdain and ultimately what competing vision do they offer? That you all should be in chains? That we should just be wage slaves? We should just accept that every year our money deteriorates in value? That we should just accept that the rich will get richer the poor get poorer? Every now and then they throw us table scraps and when we get real angry they usurp the movements and then install their own leadership to basically take those movements from us as we've seen so many times before and we will see again. I'm sorry that's not a road I want to walk down and I'm willing to ride rocky waters, crazy markets, crazy people in unlimited FUD and trolling but I will never apologize for believing in the best in people and I will never apologize for believing that if only we give everyone around us the tools to save themselves and society that they can do it.
They don't need great leaders and charisma. No one needs someone to tell them what to do. We all know what to do. We all know how to make the world a better place. We just have to be trusted enough to do it ourselves. You know what for the first time ever we did with bitcoin and then we did it again with ethereum and now we're doing it again with Cardano and we as a movement will continue to do it.
I believe our best days are ahead of us and every day I wake up and there's more people marching with me in that respect and one day it'll be millions and one day it'll be billions and one day all those cynics will be gone, replaced with optimists, who once again believe that tomorrow is going to be better than today and that we're going to leave the world just a little bit better than the way we found it. So, every now and then on a tough day I like making a little message and letting you guys all know it's going to be better and you know what? it will be. Just have to have faith that it will be. So, hold the line, hold strong and have faith in each other and go do something, build something, start something.
Got a lot of podcasts on the way, a lot of things coming down the pipe. For the dc-fund, a lot of opportunities to actually innovate. Multi assets are coming, soon Plutus is coming, soon guys are going to be able to build a lot. Start thinking today what's the business plan? What would you like to change, small or large. You don't complain about voting. Change voting. Your own organization, maybe you belong to a club, do a blockchain-based voting system. Maybe you have some political influence? Have a primary, democrat or republican, or your local primary or country for selecting candidates done with blockchain-based voting. Maybe you want to build a new financial product? Think about it, figure it out. There's so much there, it's all there, it's ready to go, it's for you to take and build and innovate with.
Every day I wake up I try to make the platforms better. I try to push the technology a little further along. I try to hire great people and bring them into our industry. Cardano brought the Haskell industry into the cryptocurrency space. Cardano brought a lot of academics who had never thought about cryptocurrencies into the cryptocurrency space and we made our problems their problems and as a consequence they started solving them in ways we could have never done before. Most importantly Cardano brought a lot of you into the cryptocurrency space and you never thought you'd have this level of control and freedom over the fabric of society in the direction of the human race. Don't let that slip through your fingers. Figure out what you want to do with that super power. Might be small, might be big. I dreamed big, you can dream big too, even if you want to just dream small. Every person counts, every action counts up to the hill. Y'all matter to me and to each other and we're all in this together, never forget that! So, hard day, rough day, tomorrow will be a better one. The day after will even be better. See you guys soon, take care...

d down, k up, everybody's a game theorist, titcoin, build wiki on Cardano, (e-)voting, competitive marketing analysis, Goguen product update, Alexa likes Charles, David hates all, Adam in and bros in arms with the scientific counterparts of the major cryptocurrency groups, the latest AMA for all!

Decreasing d parameter
Just signed the latest change management document, I was the last in the chain so I signed it today for changing the d parameter from 0.52 to 0.5. That means we are just about to cross the threshold here in a little bit for d to fall below 0.5 which means more than half of all the blocks will be made by the community and not the OBFT nodes. That's a major milestone and at this current rate of velocity it looks like d will decrement to zero around March so lots to do, lots to talk about. Product update, two days from now, we'll go ahead and talk about that but it crossed my desk today and I was really happy and excited about that and it seemed like yesterday that d was equal to one and people were complaining that we delayed it by an epoch and now we're almost at 50 percent. For those of you who want parameter-level changes, k-level changes, they are coming and there's an enormous internal conversation about it and we've written up a powerpoint presentation and a philosophy document about why things were designed the way that they're designed.
Increasing k parameter and upcoming security video and everybody's a game theorist
My chief scientist has put an enormous amount of time into this. Aggelos is very passionate about this particular topic and what I'm going to do is similar to the security video that I did where I did an hour and a half discussion about a best practice for security. I'm going to actually do a screencasted video where I talk about this philosophy document and I'm going to read the entire document with annotations with you guys and kind of talk through it. It might end up being quite a long video. It could be several hours long but I think it's really important to talk around the design philosophy of this. It's kind of funny, everybody, when they see a cryptographic paper or math paper, they tend to just say okay you guys figure that out. No one's an expert in cryptography or math and you don't really get strong opinions about it but game theory despite the fact that the topics as complex and in some cases more complex you tend to get a lot of opinions and everybody's a game theorist. So, there was enormous amount of thought that went into the design of the system, the parameters of system, everything from the reward functions to other things and it's very important that we explain that thought process in as detailed of a way as possible. At least the philosophy behind it then I feel that the community is in a really good position to start working on the change management. It is my position that I'd love to see k largely increased. I do think that the software needs some improvements to get there especially partial delegation delegation portfolios and some enhancements into the operation of staking especially.
E-voting
I'd love to see the existence of hybrid wallets where you have a cold part a hot part and we've had a lot of conversations about that and we will present some of the progress in that matter at the product updates. If not this October certainly in November. A lot of commercialization going along, a lot of things going on and flowing around and you know, commercial teams working hard. As I mentioned we have a lot of deals in the pipeline. The Wyoming event was half political, half sales. We were really looking into e-voting and we had very productive conversations along those lines. It is my goal that Cardano e-voting software is used in political primaries and my hope is for eventually to be used in municipal and state and eventually federal elections and then in national elections for countries like Ethiopia, Mongolia and other places. Now there is a long road, long, long road to get there and many little victories that have to begin but this event. Wyoming was kind of the opener into that conversation there were seven independent parties at the independent national convention and we had a chance to talk to the leadership of many of them. We will also engage in conversation with the libertarian party leadership as well and at the very least we could talk about e-voting and also blockchain-based voting for primaries that would be great start and we'll also look into the state of Wyoming for that as well. We'll you know, tell you guys about that in time. We've already gotten a lot of inquiries about e-voting software. We tend to get them along with the (Atala) Prism inquiries. It's actually quite easy to start conversations but there are a lot of security properties that are very important like end-to-end verifiability hybrid ballots where you have both a digital and a paper ballot delegation mechanics as well as privacy mechanics that are interesting on a case-by-case basis.
Goguen, voting, future fund3, competitive marketing analysis of Ouroboros vs. EOS, Tezos, Algorand, ETH2 and Polkadot, new creative director
We'll keep chipping away at that, a lot of Goguen stuff to talk about but I'm going to reserve all of that for two days from now for the product update. We're right in the middle, Goguen metadata was the very first part of it. We already have some commercialization platform as a result of metadata, more to come and then obviously lots of smart contract stuff to come. This update and the November update are going to be very Goguen focused and also a lot of alternatives as well. We're still on schedule for an HFC event in I think November or December. I can't remember but that's going to be carrying a lot of things related multisig token locking. There's some ledger rule changes so it has to be an HFC event and that opens up a lot of the windows for Goguen foundations as well as voting on chain so fund3 will benefit very heavily from that. We're right in the guts of Daedalus right now building the voting center, the identity center, QR-code work. All this stuff, it's a lot of stuff, you know, the cell phone app was released last week. Kind of an early beta, it'll go through a lot of rapid iterations every few weeks. We'll update it, google play is a great foundation to launch things on because it's so easy to push updates to people automatically so you can rapidly iterate and be very agile in that framework and you know we've already had 3500 people involved heavily in the innovation management platform ideascale and we've got numerous bids from everything. From John Buck and the sociocracy movement to others. A lot of people want to help us improve that and we're going to see steady and systematic growth there. We're still chipping away at product marketing. Liza (Horowitz) is doing a good job, meet with her two three-times a week and right now it's Ouroboros, Ouroboros, Ouroboros... We're doing competitive analysis of Ouroboros versus EOS, Tezos, Algorand, ETH2 and Polkadot. We think that's a good set. We think we have a really good way of explaining it. David (David Likes Crypto now at IOHK) has already made some great content. We're going to release that soon alongside some other content and we'll keep chipping away at that.
We also just hired a creative director for IO Global. His name's Adam, incredibly experienced creative director, he's worked for Mercedes-Benz and dozens of other companies. He does very good work and he's been doing this for well over 20 years and so the very first set of things he's going to do is work with commercial and marketing on product marketing. In addition to building great content where hope is make that content as pretty as possible and we have Rod heavily involved in that as well to talk about distribution channels and see if we can amplify the distribution message and really get a lot of stuff done. Last thing to mention, oh yeah, iOS for catalyst. We're working on that, we submitted it to the apple store, the iOS store, but it takes a little longer to get approval for that than it does with google play but that's been submitted and it's whenever apple approves it or not. Takes a little longer for cryptocurrency stuff.
Wiki shizzle and battle for crypto, make crypto articles on wiki great again, Alexa knows Charles, Everpedia meets Charles podcast, holy-grail land of Cardano, wiki on Cardano, titcoin
Wikipedia... kind of rattled the cage a little bit. Through an intermediary we got contact with Jimmy Wales. Larry Sanger, the other co-founder also reached out to me and the everpedia guys reached out to me. Here's where we stand, we have an article, it has solidified, it's currently labeled as unreliable and you should not believe the things that are said in it which is David Gerard's work if you look at the edits. We will work with the community and try to get that article to a fair and balanced representation of Cardano and especially after the product marketing comes through. We clearly explain the product I think the Cardano article can be massively strengthened. I've told Rod to work with some specialized people to try to get that done but we are going to work very hard at a systematic approval campaign for all of the scientific articles related to blockchain technology in the cryptocurrency space. They're just terrible, if you go to the proof of work article, the proof of stake or all these things, they're just terrible. They're not well written, they're out of date and they don't reflect an adequate sampling of the science. I did talk to my chief scientist Aggelos and what we're gonna do is reach out to the scientific counterparts that most of the major cryptocurrency groups that are doing research and see if they want to work with us at an industry-wide effort to systematically improve the scientific articles in our industry so that there are a fair and balanced representation of what the current state of the art are, the criticisms, the trade-offs as well as the reference space and of course obviously we'll do quite well in that respect because we've done the science. We're the inheritor of it but it's a shame because when people search proof of stake on google usually wikipedia results are highly biased. We care about wikipedia because google cares about wikipedia, amazon cares about wikipedia.
If you ask Alexa who is Charles Hoskinson, the reason why Alexa knows is because it's reading directly from the wikipedia page. If I didn't have a wikipedia page Alexa would know that so if somebody says Alexa what is Cardano it's going to read directly from the wikipedia page and you know and we can either just pretend that reality doesn't exist or we can accept it and we as a community working with partners in the broader cryptocurrency community can universally improve the quality of cryptocurrency pages. There's been a pattern of commercial censorship on wikipedia for cryptocurrencies in general since bitcoin itself. In fact I think the bitcoin article is actually taken down once back in, might have been, 2010 or 2009 but basically wikipedia has not been a friend of cryptocurrencies. That's why everpedia exists and actually their founders reached out to me and I talked to them over twitter through PMs and we agreed to actually do a podcast. I'm going to do a streamyard, stream with these guys and they'll come on talk all about everpedia and what they do and how they are and we'll kind of go through the challenges that they've encountered. How their platform works and so forth and obviously if they want to ever leave that terrible ecosystem EOS and come to the holy-grail land of Cardano we'd be there to help them out. At least they can tell the world how amazing their product is and also the challenges they're having to overcome. We've also been in great contact with Larry Sanger.
He's going to do an internal seminar at some point with with us and talk about some protocols he's been developing since he left wikipedia specifically to decentralize knowledge management and have a truly decentralized encyclopedia. I'm really looking forward to that and I hope that presentation gives us some inspiration as an ecosystem of things we can do. That's a great piece of infrastructure regardless and after we learn a lot more about it and we talk to a lot of people in ecosystem. If we can't get people to move on over, it would be really good to see through ideascale in the innovation management platform for people to utilize the dc fund to build their own variant of wikipedia on Cardano. In the coming months there will certainly be funding available. If you guys are so passionate about this particular problem that you want to go solve it then I'd be happy to play Elon Musk with the hyperloop and write a white paper on a protocol design and really give a good first start and then you guys can go and try to commercialize that technology as Cardano native assets and Plutus smart contracts in addition to other pieces of technology that have to be brought in to make it practical.
Right now we're just, let's talk to everybody phase, and we'll talk to the everpedia guys, we're going to talk to Larry and we're going to see whoever else is in this game and of course we have to accept the incumbency as it is. So, we're working with obviously the wikipedia side to improve the quality of not only our article but all of the articles and the scientific side of things so that there's a fair and accurate representation of information. One of the reasons why I'm so concerned about this is that I am very worried that Cardano projects will get commercially censored like we were commercially censored. So, yes we do have a page but it took five years to get there and we're a multi-billion dollar project with hundreds of thousands of people. If you guys are doing cutting-edge novel interesting stuff I don't want your experience to be the same as ours where you have to wait five years for your project to get a page even after government's adopted. That's absurd, no one should be censored ever. This is very well a fight for the entire ecosystem, the entire community, not just Cardano but all cryptocurrencies: bitcoin, ethereum and Cardano have all faced commercial censorship and article deletions during their tenure so I don't want you guys to go through that. I'm hoping we can prove that situation but you know you don't put all your eggs in one basket and frankly the time has come for wikipedia to be fully decentralized and liberated from a centralized organization and massively variable quality in the editor base. If legends of valor has a page but Cardano didn't have one until recently titcoin, a pornography coin from 2015, that's deprecated, no one uses it, has a page but Cardano couldn't get one there's something seriously wrong with the quality control mechanism and we need to improve that so it'll get done.

Technical: Taproot: Why Activate?

This is a follow-up on https://old.reddit.com/Bitcoin/comments/hqzp14/technical_the_path_to_taproot_activation/
Taproot! Everybody wants it!! But... you might ask yourself: sure, everybody else wants it, but why would I, sovereign Bitcoin HODLer, want it? Surely I can be better than everybody else because I swapped XXX fiat for Bitcoin unlike all those nocoiners?
And it is important for you to know the reasons why you, o sovereign Bitcoiner, would want Taproot activated. After all, your nodes (or the nodes your wallets use, which if you are SPV, you hopefully can pester to your wallet vendoimplementor about) need to be upgraded in order for Taproot activation to actually succeed instead of becoming a hot sticky mess.
First, let's consider some principles of Bitcoin.
I'm sure most of us here would agree that the above are very important principles of Bitcoin and that these are principles we would not be willing to remove. If anything, we would want those principles strengthened (especially the last one, financial privacy, which current Bitcoin is only sporadically strong with: you can get privacy, it just requires effort to do so).
So, how does Taproot affect those principles?

Taproot and Your /Coins

Most HODLers probably HODL their coins in singlesig addresses. Sadly, switching to Taproot would do very little for you (it gives a mild discount at spend time, at the cost of a mild increase in fee at receive time (paid by whoever sends to you, so if it's a self-send from a P2PKH or bech32 address, you pay for this); mostly a wash).
(technical details: a Taproot output is 1 version byte + 32 byte public key, while a P2WPKH (bech32 singlesig) output is 1 version byte + 20 byte public key hash, so the Taproot output spends 12 bytes more; spending from a P2WPKH requires revealing a 32-byte public key later, which is not needed with Taproot, and Taproot signatures are about 9 bytes smaller than P2WPKH signatures, but the 32 bytes plus 9 bytes is divided by 4 because of the witness discount, so it saves about 11 bytes; mostly a wash, it increases blockweight by about 1 virtual byte, 4 weight for each Taproot-output-input, compared to P2WPKH-output-input).
However, as your HODLings grow in value, you might start wondering if multisignature k-of-n setups might be better for the security of your savings. And it is in multisignature that Taproot starts to give benefits!
Taproot switches to using Schnorr signing scheme. Schnorr makes key aggregation -- constructing a single public key from multiple public keys -- almost as trivial as adding numbers together. "Almost" because it involves some fairly advanced math instead of simple boring number adding, but hey when was the last time you added up your grocery list prices by hand huh?
With current P2SH and P2WSH multisignature schemes, if you have a 2-of-3 setup, then to spend, you need to provide two different signatures from two different public keys. With Taproot, you can create, using special moon math, a single public key that represents your 2-of-3 setup. Then you just put two of your devices together, have them communicate to each other (this can be done airgapped, in theory, by sending QR codes: the software to do this is not even being built yet, but that's because Taproot hasn't activated yet!), and they will make a single signature to authorize any spend from your 2-of-3 address. That's 73 witness bytes -- 18.25 virtual bytes -- of signatures you save!
And if you decide that your current setup with 1-of-1 P2PKH / P2WPKH addresses is just fine as-is: well, that's the whole point of a softfork: backwards-compatibility; you can receive from Taproot users just fine, and once your wallet is updated for Taproot-sending support, you can send to Taproot users just fine as well!
(P2WPKH and P2WSH -- SegWit v0 -- addresses start with bc1q; Taproot -- SegWit v1 --- addresses start with bc1p, in case you wanted to know the difference; in bech32 q is 0, p is 1)
Now how about HODLers who keep all, or some, of their coins on custodial services? Well, any custodial service worth its salt would be doing at least 2-of-3, or probably something even bigger, like 11-of-15. So your custodial service, if it switched to using Taproot internally, could save a lot more (imagine an 11-of-15 getting reduced from 11 signatures to just 1!), which --- we can only hope! --- should translate to lower fees and better customer service from your custodial service!
So I think we can say, very accurately, that the Bitcoin principle --- that YOU are in control of your money --- can only be helped by Taproot (if you are doing multisignature), and, because P2PKH and P2WPKH remain validly-usable addresses in a Taproot future, will not be harmed by Taproot. Its benefit to this principle might be small (it mostly only benefits multisignature users) but since it has no drawbacks with this (i.e. singlesig users can continue to use P2WPKH and P2PKH still) this is still a nice, tidy win!
(even singlesig users get a minor benefit, in that multisig users will now reduce their blockchain space footprint, so that fees can be kept low for everybody; so for example even if you have your single set of private keys engraved on titanium plates sealed in an airtight box stored in a safe buried in a desert protected by angry nomads riding giant sandworms because you're the frickin' Kwisatz Haderach, you still gain some benefit from Taproot)
And here's the important part: if P2PKH/P2WPKH is working perfectly fine with you and you decide to never use Taproot yourself, Taproot will not affect you detrimentally. First do no harm!

Taproot and Your Contracts

No one is an island, no one lives alone. Give and you shall receive. You know: by trading with other people, you can gain expertise in some obscure little necessity of the world (and greatly increase your productivity in that little field), and then trade the products of your expertise for necessities other people have created, all of you thereby gaining gains from trade.
So, contracts, which are basically enforceable agreements that facilitate trading with people who you do not personally know and therefore might not trust.
Let's start with a simple example. You want to buy some gewgaws from somebody. But you don't know them personally. The seller wants the money, you want their gewgaws, but because of the lack of trust (you don't know them!! what if they're scammers??) neither of you can benefit from gains from trade.
However, suppose both of you know of some entity that both of you trust. That entity can act as a trusted escrow. The entity provides you security: this enables the trade, allowing both of you to get gains from trade.
In Bitcoin-land, this can be implemented as a 2-of-3 multisignature. The three signatories in the multisgnature would be you, the gewgaw seller, and the escrow. You put the payment for the gewgaws into this 2-of-3 multisignature address.
Now, suppose it turns out neither of you are scammers (whaaaat!). You receive the gewgaws just fine and you're willing to pay up for them. Then you and the gewgaw seller just sign a transaction --- you and the gewgaw seller are 2, sufficient to trigger the 2-of-3 --- that spends from the 2-of-3 address to a singlesig the gewgaw seller wants (or whatever address the gewgaw seller wants).
But suppose some problem arises. The seller gave you gawgews instead of gewgaws. Or you decided to keep the gewgaws but not sign the transaction to release the funds to the seller. In either case, the escrow is notified, and if it can sign with you to refund the funds back to you (if the seller was a scammer) or it can sign with the seller to forward the funds to the seller (if you were a scammer).
Taproot helps with this: like mentioned above, it allows multisignature setups to produce only one signature, reducing blockchain space usage, and thus making contracts --- which require multiple people, by definition, you don't make contracts with yourself --- is made cheaper (which we hope enables more of these setups to happen for more gains from trade for everyone, also, moon and lambos).
(technology-wise, it's easier to make an n-of-n than a k-of-n, making a k-of-n would require a complex setup involving a long ritual with many communication rounds between the n participants, but an n-of-n can be done trivially with some moon math. You can, however, make what is effectively a 2-of-3 by using a three-branch SCRIPT: either 2-of-2 of you and seller, OR 2-of-2 of you and escrow, OR 2-of-2 of escrow and seller. Fortunately, Taproot adds a facility to embed a SCRIPT inside a public key, so you can have a 2-of-2 Taprooted address (between you and seller) with a SCRIPT branch that can instead be spent with 2-of-2 (you + escrow) OR 2-of-2 (seller + escrow), which implements the three-branched SCRIPT above. If neither of you are scammers (hopefully the common case) then you both sign using your keys and never have to contact the escrow, since you are just using the escrow public key without coordinating with them (because n-of-n is trivial but k-of-n requires setup with communication rounds), so in the "best case" where both of you are honest traders, you also get a privacy boost, in that the escrow never learns you have been trading on gewgaws, I mean ewww, gawgews are much better than gewgaws and therefore I now judge you for being a gewgaw enthusiast, you filthy gewgawer).

Taproot and Your Contracts, Part 2: Cryptographic Boogaloo

Now suppose you want to buy some data instead of things. For example, maybe you have some closed-source software in trial mode installed, and want to pay the developer for the full version. You want to pay for an activation code.
This can be done, today, by using an HTLC. The developer tells you the hash of the activation code. You pay to an HTLC, paying out to the developer if it reveals the preimage (the activation code), or refunding the money back to you after a pre-agreed timeout. If the developer claims the funds, it has to reveal the preimage, which is the activation code, and you can now activate your software. If the developer does not claim the funds by the timeout, you get refunded.
And you can do that, with HTLCs, today.
Of course, HTLCs do have problems:
Fortunately, with Schnorr (which is enabled by Taproot), we can now use the Scriptless Script constuction by Andrew Poelstra. This Scriptless Script allows a new construction, the PTLC or Pointlocked Timelocked Contract. Instead of hashes and preimages, just replace "hash" with "point" and "preimage" with "scalar".
Or as you might know them: "point" is really "public key" and "scalar" is really a "private key". What a PTLC does is that, given a particular public key, the pointlocked branch can be spent only if the spender reveals the private key of the given public key to you.
Another nice thing with PTLCs is that they are deniable. What appears onchain is just a single 2-of-2 signature between you and the developemanufacturer. It's like a magic trick. This signature has no special watermarks, it's a perfectly normal signature (the pledge). However, from this signature, plus some datta given to you by the developemanufacturer (known as the adaptor signature) you can derive the private key of a particular public key you both agree on (the turn). Anyone scraping the blockchain will just see signatures that look just like every other signature, and as long as nobody manages to hack you and get a copy of the adaptor signature or the private key, they cannot get the private key behind the public key (point) that the pointlocked branch needs (the prestige).
(Just to be clear, the public key you are getting the private key from, is distinct from the public key that the developemanufacturer will use for its funds. The activation key is different from the developer's onchain Bitcoin key, and it is the activation key whose private key you will be learning, not the developer's/manufacturer's onchain Bitcoin key).
So:
Taproot lets PTLCs exist onchain because they enable Schnorr, which is a requirement of PTLCs / Scriptless Script.
(technology-wise, take note that Scriptless Script works only for the "pointlocked" branch of the contract; you need normal Script, or a pre-signed nLockTimed transaction, for the "timelocked" branch. Since Taproot can embed a script, you can have the Taproot pubkey be a 2-of-2 to implement the Scriptless Script "pointlocked" branch, then have a hidden script that lets you recover the funds with an OP_CHECKLOCKTIMEVERIFY after the timeout if the seller does not claim the funds.)

Quantum Quibbles!

Now if you were really paying attention, you might have noticed this parenthetical:
(technical details: a Taproot output is 1 version byte + 32 byte public key, while a P2WPKH (bech32 singlesig) output is 1 version byte + 20 byte public key hash...)
So wait, Taproot uses raw 32-byte public keys, and not public key hashes? Isn't that more quantum-vulnerable??
Well, in theory yes. In practice, they probably are not.
It's not that hashes can be broken by quantum computes --- they're still not. Instead, you have to look at how you spend from a P2WPKH/P2PKH pay-to-public-key-hash.
When you spend from a P2PKH / P2WPKH, you have to reveal the public key. Then Bitcoin hashes it and checks if this matches with the public-key-hash, and only then actually validates the signature for that public key.
So an unconfirmed transaction, floating in the mempools of nodes globally, will show, in plain sight for everyone to see, your public key.
(public keys should be public, that's why they're called public keys, LOL)
And if quantum computers are fast enough to be of concern, then they are probably fast enough that, in the several minutes to several hours from broadcast to confirmation, they have already cracked the public key that is openly broadcast with your transaction. The owner of the quantum computer can now replace your unconfirmed transaction with one that pays the funds to itself. Even if you did not opt-in RBF, miners are still incentivized to support RBF on RBF-disabled transactions.
So the extra hash is not as significant a protection against quantum computers as you might think. Instead, the extra hash-and-compare needed is just extra validation effort.
Further, if you have ever, in the past, spent from the address, then there exists already a transaction indelibly stored on the blockchain, openly displaying the public key from which quantum computers can derive the private key. So those are still vulnerable to quantum computers.
For the most part, the cryptographers behind Taproot (and Bitcoin Core) are of the opinion that quantum computers capable of cracking Bitcoin pubkeys are unlikely to appear within a decade or two.
So:
For now, the homomorphic and linear properties of elliptic curve cryptography provide a lot of benefits --- particularly the linearity property is what enables Scriptless Script and simple multisignature (i.e. multisignatures that are just 1 signature onchain). So it might be a good idea to take advantage of them now while we are still fairly safe against quantum computers. It seems likely that quantum-safe signature schemes are nonlinear (thus losing these advantages).

Summary

I Wanna Be The Taprooter!

So, do you want to help activate Taproot? Here's what you, mister sovereign Bitcoin HODLer, can do!

But I Hate Taproot!!

That's fine!

Parallel.For uses 50-70% of CPU part 2 (narrowed down to some BigInteger math)

A while ago I asked about this problem I had with Parallel.For where it used all cores but only at ~60%. Thanks to all the excellent advice I received here I was able to narrow down the problem to 3 parts of the code. 1. The way I was creating the IEnumerable which I replaced with a simple array (special thanks to u/panoskj) 2. A bug where different threads were actually writing to the same buffers inside ICompareService which was a global instance instead of being created for each thread (but this also suffers from 3). 3. Some math involving BigInteger on this line.
Out of these 3 I've fixed 1 and 2 and they make sense but I can't figure out why the third one is causing problems and I need help again (haven't published these changes on GitHub due to being incomplete). If I comment out L329 and replace L467 with a simple array comparison the parallel loop can successfully use 100% CPU on all cores.
I am creating both the calculator and the generator (starting point) inside each thread although I don't think it matters. The full calculator code can be seen here: https://github.com/Coding-Enthusiast/FinderOutetree/masteSrc/FinderOuteBackend/Asymmetric/EllipticCurve The relevant code for the method being called is this (Elliptic Curve point multiplication):
internal EllipticCurvePoint MultiplyChecked(BigInteger k, EllipticCurvePoint point) { EllipticCurvePoint result = EllipticCurvePoint.InfinityPoint; EllipticCurvePoint addend = point; while (k != 0) { if ((k & 1) == 1) { result = AddChecked(result, addend); } addend = DoubleChecked(addend); k >>= 1; } return result; } internal EllipticCurvePoint AddChecked(EllipticCurvePoint point1, EllipticCurvePoint point2) { if (point1 == EllipticCurvePoint.InfinityPoint) return point2; if (point2 == EllipticCurvePoint.InfinityPoint) return point1; BigInteger m; if (point1.X == point2.X) { if (point1.Y != point2.Y) // (x,y) + (x,−y) = O { return EllipticCurvePoint.InfinityPoint; } // Point double or (x,y) + (x,y) m = ((3 * point1.X * point1.X) + curve.A) * (2 * point1.Y).ModInverse(curve.P); // Note that since points are on a group with a prime (mod p) all of them do have multiplicative inverses. } else // point1 != point2. (x1,y1) + (x2,y2) { m = (point1.Y - point2.Y) * (point1.X - point2.X).ModInverse(curve.P); } BigInteger x3 = ((m * m) - point1.X - point2.X).Mod(curve.P); BigInteger y3 = (m * (point1.X - x3) - point1.Y).Mod(curve.P); return new EllipticCurvePoint(x3, y3); } internal EllipticCurvePoint DoubleChecked(EllipticCurvePoint point1) { if (point1 == EllipticCurvePoint.InfinityPoint) return point1; BigInteger m = 3 * point1.X * point1.X * (2 * point1.Y).ModInverse(curve.P); BigInteger x3 = ((m * m) - (2 * point1.X)).Mod(curve.P); BigInteger y3 = (m * (point1.X - x3) - point1.Y).Mod(curve.P); return new EllipticCurvePoint(x3, y3); } 
EllipticCurvePoint is a struct with 2 readonly BigInteger properties
public struct EllipticCurvePoint : IEquatable { public EllipticCurvePoint(BigInteger x, BigInteger y) { X = x; Y = y; } public BigInteger X { get; } public BigInteger Y { get; }

How far cryptography skills allows you to gain more money?

Hello, I have been wondering whether skills in cryptography allows someone to gain more money from the cryptocurrency world. Are math skills beneficial in cryptocurrency mining math puzzles? Are there pathways other than cryptocurrency mining which are profitable for someone with mathematical skills?

[ Bitcoin ] Technical: Taproot: Why Activate?

Topic originally posted in Bitcoin by almkglor [link]
This is a follow-up on https://old.reddit.com/Bitcoin/comments/hqzp14/technical_the_path_to_taproot_activation/
Taproot! Everybody wants it!! But... you might ask yourself: sure, everybody else wants it, but why would I, sovereign Bitcoin HODLer, want it? Surely I can be better than everybody else because I swapped XXX fiat for Bitcoin unlike all those nocoiners?
And it is important for you to know the reasons why you, o sovereign Bitcoiner, would want Taproot activated. After all, your nodes (or the nodes your wallets use, which if you are SPV, you hopefully can pester to your wallet vendoimplementor about) need to be upgraded in order for Taproot activation to actually succeed instead of becoming a hot sticky mess.
First, let's consider some principles of Bitcoin.
I'm sure most of us here would agree that the above are very important principles of Bitcoin and that these are principles we would not be willing to remove. If anything, we would want those principles strengthened (especially the last one, financial privacy, which current Bitcoin is only sporadically strong with: you can get privacy, it just requires effort to do so).
So, how does Taproot affect those principles?

Taproot and Your /Coins

Most HODLers probably HODL their coins in singlesig addresses. Sadly, switching to Taproot would do very little for you (it gives a mild discount at spend time, at the cost of a mild increase in fee at receive time (paid by whoever sends to you, so if it's a self-send from a P2PKH or bech32 address, you pay for this); mostly a wash).
(technical details: a Taproot output is 1 version byte + 32 byte public key, while a P2WPKH (bech32 singlesig) output is 1 version byte + 20 byte public key hash, so the Taproot output spends 12 bytes more; spending from a P2WPKH requires revealing a 32-byte public key later, which is not needed with Taproot, and Taproot signatures are about 9 bytes smaller than P2WPKH signatures, but the 32 bytes plus 9 bytes is divided by 4 because of the witness discount, so it saves about 11 bytes; mostly a wash, it increases blockweight by about 1 virtual byte, 4 weight for each Taproot-output-input, compared to P2WPKH-output-input).
However, as your HODLings grow in value, you might start wondering if multisignature k-of-n setups might be better for the security of your savings. And it is in multisignature that Taproot starts to give benefits!
Taproot switches to using Schnorr signing scheme. Schnorr makes key aggregation -- constructing a single public key from multiple public keys -- almost as trivial as adding numbers together. "Almost" because it involves some fairly advanced math instead of simple boring number adding, but hey when was the last time you added up your grocery list prices by hand huh?
With current P2SH and P2WSH multisignature schemes, if you have a 2-of-3 setup, then to spend, you need to provide two different signatures from two different public keys. With Taproot, you can create, using special moon math, a single public key that represents your 2-of-3 setup. Then you just put two of your devices together, have them communicate to each other (this can be done airgapped, in theory, by sending QR codes: the software to do this is not even being built yet, but that's because Taproot hasn't activated yet!), and they will make a single signature to authorize any spend from your 2-of-3 address. That's 73 witness bytes -- 18.25 virtual bytes -- of signatures you save!
And if you decide that your current setup with 1-of-1 P2PKH / P2WPKH addresses is just fine as-is: well, that's the whole point of a softfork: backwards-compatibility; you can receive from Taproot users just fine, and once your wallet is updated for Taproot-sending support, you can send to Taproot users just fine as well!
(P2WPKH and P2WSH -- SegWit v0 -- addresses start with bc1q; Taproot -- SegWit v1 --- addresses start with bc1p, in case you wanted to know the difference; in bech32 q is 0, p is 1)
Now how about HODLers who keep all, or some, of their coins on custodial services? Well, any custodial service worth its salt would be doing at least 2-of-3, or probably something even bigger, like 11-of-15. So your custodial service, if it switched to using Taproot internally, could save a lot more (imagine an 11-of-15 getting reduced from 11 signatures to just 1!), which --- we can only hope! --- should translate to lower fees and better customer service from your custodial service!
So I think we can say, very accurately, that the Bitcoin principle --- that YOU are in control of your money --- can only be helped by Taproot (if you are doing multisignature), and, because P2PKH and P2WPKH remain validly-usable addresses in a Taproot future, will not be harmed by Taproot. Its benefit to this principle might be small (it mostly only benefits multisignature users) but since it has no drawbacks with this (i.e. singlesig users can continue to use P2WPKH and P2PKH still) this is still a nice, tidy win!
(even singlesig users get a minor benefit, in that multisig users will now reduce their blockchain space footprint, so that fees can be kept low for everybody; so for example even if you have your single set of private keys engraved on titanium plates sealed in an airtight box stored in a safe buried in a desert protected by angry nomads riding giant sandworms because you're the frickin' Kwisatz Haderach, you still gain some benefit from Taproot)
And here's the important part: if P2PKH/P2WPKH is working perfectly fine with you and you decide to never use Taproot yourself, Taproot will not affect you detrimentally. First do no harm!

Taproot and Your Contracts

No one is an island, no one lives alone. Give and you shall receive. You know: by trading with other people, you can gain expertise in some obscure little necessity of the world (and greatly increase your productivity in that little field), and then trade the products of your expertise for necessities other people have created, all of you thereby gaining gains from trade.
So, contracts, which are basically enforceable agreements that facilitate trading with people who you do not personally know and therefore might not trust.
Let's start with a simple example. You want to buy some gewgaws from somebody. But you don't know them personally. The seller wants the money, you want their gewgaws, but because of the lack of trust (you don't know them!! what if they're scammers??) neither of you can benefit from gains from trade.
However, suppose both of you know of some entity that both of you trust. That entity can act as a trusted escrow. The entity provides you security: this enables the trade, allowing both of you to get gains from trade.
In Bitcoin-land, this can be implemented as a 2-of-3 multisignature. The three signatories in the multisgnature would be you, the gewgaw seller, and the escrow. You put the payment for the gewgaws into this 2-of-3 multisignature address.
Now, suppose it turns out neither of you are scammers (whaaaat!). You receive the gewgaws just fine and you're willing to pay up for them. Then you and the gewgaw seller just sign a transaction --- you and the gewgaw seller are 2, sufficient to trigger the 2-of-3 --- that spends from the 2-of-3 address to a singlesig the gewgaw seller wants (or whatever address the gewgaw seller wants).
But suppose some problem arises. The seller gave you gawgews instead of gewgaws. Or you decided to keep the gewgaws but not sign the transaction to release the funds to the seller. In either case, the escrow is notified, and if it can sign with you to refund the funds back to you (if the seller was a scammer) or it can sign with the seller to forward the funds to the seller (if you were a scammer).
Taproot helps with this: like mentioned above, it allows multisignature setups to produce only one signature, reducing blockchain space usage, and thus making contracts --- which require multiple people, by definition, you don't make contracts with yourself --- is made cheaper (which we hope enables more of these setups to happen for more gains from trade for everyone, also, moon and lambos).
(technology-wise, it's easier to make an n-of-n than a k-of-n, making a k-of-n would require a complex setup involving a long ritual with many communication rounds between the n participants, but an n-of-n can be done trivially with some moon math. You can, however, make what is effectively a 2-of-3 by using a three-branch SCRIPT: either 2-of-2 of you and seller, OR 2-of-2 of you and escrow, OR 2-of-2 of escrow and seller. Fortunately, Taproot adds a facility to embed a SCRIPT inside a public key, so you can have a 2-of-2 Taprooted address (between you and seller) with a SCRIPT branch that can instead be spent with 2-of-2 (you + escrow) OR 2-of-2 (seller + escrow), which implements the three-branched SCRIPT above. If neither of you are scammers (hopefully the common case) then you both sign using your keys and never have to contact the escrow, since you are just using the escrow public key without coordinating with them (because n-of-n is trivial but k-of-n requires setup with communication rounds), so in the "best case" where both of you are honest traders, you also get a privacy boost, in that the escrow never learns you have been trading on gewgaws, I mean ewww, gawgews are much better than gewgaws and therefore I now judge you for being a gewgaw enthusiast, you filthy gewgawer).

Taproot and Your Contracts, Part 2: Cryptographic Boogaloo

Now suppose you want to buy some data instead of things. For example, maybe you have some closed-source software in trial mode installed, and want to pay the developer for the full version. You want to pay for an activation code.
This can be done, today, by using an HTLC. The developer tells you the hash of the activation code. You pay to an HTLC, paying out to the developer if it reveals the preimage (the activation code), or refunding the money back to you after a pre-agreed timeout. If the developer claims the funds, it has to reveal the preimage, which is the activation code, and you can now activate your software. If the developer does not claim the funds by the timeout, you get refunded.
And you can do that, with HTLCs, today.
Of course, HTLCs do have problems:
Fortunately, with Schnorr (which is enabled by Taproot), we can now use the Scriptless Script constuction by Andrew Poelstra. This Scriptless Script allows a new construction, the PTLC or Pointlocked Timelocked Contract. Instead of hashes and preimages, just replace "hash" with "point" and "preimage" with "scalar".
Or as you might know them: "point" is really "public key" and "scalar" is really a "private key". What a PTLC does is that, given a particular public key, the pointlocked branch can be spent only if the spender reveals the private key of the given private key to you.
Another nice thing with PTLCs is that they are deniable. What appears onchain is just a single 2-of-2 signature between you and the developemanufacturer. It's like a magic trick. This signature has no special watermarks, it's a perfectly normal signature (the pledge). However, from this signature, plus some datta given to you by the developemanufacturer (known as the adaptor signature) you can derive the private key of a particular public key you both agree on (the turn). Anyone scraping the blockchain will just see signatures that look just like every other signature, and as long as nobody manages to hack you and get a copy of the adaptor signature or the private key, they cannot get the private key behind the public key (point) that the pointlocked branch needs (the prestige).
(Just to be clear, the public key you are getting the private key from, is distinct from the public key that the developemanufacturer will use for its funds. The activation key is different from the developer's onchain Bitcoin key, and it is the activation key whose private key you will be learning, not the developer's/manufacturer's onchain Bitcoin key).
So:
Taproot lets PTLCs exist onchain because they enable Schnorr, which is a requirement of PTLCs / Scriptless Script.
(technology-wise, take note that Scriptless Script works only for the "pointlocked" branch of the contract; you need normal Script, or a pre-signed nLockTimed transaction, for the "timelocked" branch. Since Taproot can embed a script, you can have the Taproot pubkey be a 2-of-2 to implement the Scriptless Script "pointlocked" branch, then have a hidden script that lets you recover the funds with an OP_CHECKLOCKTIMEVERIFY after the timeout if the seller does not claim the funds.)

Quantum Quibbles!

Now if you were really paying attention, you might have noticed this parenthetical:
(technical details: a Taproot output is 1 version byte + 32 byte public key, while a P2WPKH (bech32 singlesig) output is 1 version byte + 20 byte public key hash...)
So wait, Taproot uses raw 32-byte public keys, and not public key hashes? Isn't that more quantum-vulnerable??
Well, in theory yes. In practice, they probably are not.
It's not that hashes can be broken by quantum computes --- they're still not. Instead, you have to look at how you spend from a P2WPKH/P2PKH pay-to-public-key-hash.
When you spend from a P2PKH / P2WPKH, you have to reveal the public key. Then Bitcoin hashes it and checks if this matches with the public-key-hash, and only then actually validates the signature for that public key.
So an unconfirmed transaction, floating in the mempools of nodes globally, will show, in plain sight for everyone to see, your public key.
(public keys should be public, that's why they're called public keys, LOL)
And if quantum computers are fast enough to be of concern, then they are probably fast enough that, in the several minutes to several hours from broadcast to confirmation, they have already cracked the public key that is openly broadcast with your transaction. The owner of the quantum computer can now replace your unconfirmed transaction with one that pays the funds to itself. Even if you did not opt-in RBF, miners are still incentivized to support RBF on RBF-disabled transactions.
So the extra hash is not as significant a protection against quantum computers as you might think. Instead, the extra hash-and-compare needed is just extra validation effort.
Further, if you have ever, in the past, spent from the address, then there exists already a transaction indelibly stored on the blockchain, openly displaying the public key from which quantum computers can derive the private key. So those are still vulnerable to quantum computers.
For the most part, the cryptographers behind Taproot (and Bitcoin Core) are of the opinion that quantum computers capable of cracking Bitcoin pubkeys are unlikely to appear within a decade or two.
So:
For now, the homomorphic and linear properties of elliptic curve cryptography provide a lot of benefits --- particularly the linearity property is what enables Scriptless Script and simple multisignature (i.e. multisignatures that are just 1 signature onchain). So it might be a good idea to take advantage of them now while we are still fairly safe against quantum computers. It seems likely that quantum-safe signature schemes are nonlinear (thus losing these advantages).

Summary

I Wanna Be The Taprooter!

So, do you want to help activate Taproot? Here's what you, mister sovereign Bitcoin HODLer, can do!

But I Hate Taproot!!

How does cryptocurrency works?

How does cryptocurrency works?
When we were a much smaller society, people could trade in the community pretty easily, but as the distance in our trade grew, we ended up inventing institutions such as banks, markets, stocks etc. that help us to conduct financial transactions. The currencies we are operating with nowadays are bills or coins, controlled by a centralized authority and tracked by previously mentioned financial institutions. The thing is, having a third party in our money transactions is not always what we wish for. But fortunately, today we have a tool that allows us to make fast and save financial transactions without any middlemen, it has no central authority and it is regulated by math. Sounds cool, right? Cryptocurrency is this tool. It is quite a peculiar system, so let’s take a closer look at it.
by StealthEX

Layers of a crypto-cake

Layer 1: Blockchain

First of all – any cryptocurrency is based on the blockchain. In simple words, blockchain is a kind of a database. It stores information in batches, called blocks that are linked together in a chronological way. As the blockchain is not located in one place but rather on thousands of computers around the globe, the blockchain and the transactions thus are decentralized, they have no head center. The newest blocks of transaction are continuously added on (or changed) to all the previous blocks. That’s how you get a cryptocurrency blockchain.
The technology’s name is a compound of the words “block” and “chain”, as the “blocks” of information are linked together in a “chain”. That’s how crypto security works – the information in the recently created block depends on the previous one. It means that no block can be changed without affecting the others, this system prevents a blockchain from being hacked.
There are 2 kinds of blockchain: private and public. Public, as goes by its name, is publicly available blockchain, whereas private blockchain is permissioned, which only a limited number of people have access to.

Layer 2: Transaction

In fact, everything begins with the intention of someone to complete a transaction. A transaction itself is a file that consists of the sender’s and recipient’s public keys (wallet addresses) and the amount of coins transferred. The sender begins by logging in into his cryptocurrency wallet with the private key – a unique combination of letters and numbers, something you would call a personal password in a bank. Now the transaction is signed and the first step which is called basic public key cryptography is completed.
Then the signed (encrypted) transaction is shared with everyone in the cryptocurrency network, meaning it gets to every other peer. We should mention that the transaction is firstly queued up to be added to the public ledger. Then, when it’s broadcasted to the public ledger, all the computers add a new transaction to a shared list of recent transactions, known as blocks.
Having a ledger forces everyone to “play fair” and reduce the risk of spending extra. The numbers of transactions are publicly available, but the information about senders and receivers is encrypted. Each transaction holds on to a unique set of keys. Whoever owns a set of keys, owns the amount of cryptocurrency associated with those keys (just like whoever owns a bank account owns the money in it). This is how peer-to-peer technology works.

Layer 3: Mining

Now let’s talk about mining. Once confirmed, the transaction is forever captured into the blockchain history**.** The verification of the block is done by Cryptocurrency Miners – they verify and then add blocks to the public ledger. To verify them, miners go down on the road of solving a very difficult math puzzle using powerful software, which is that the computer needs to produce the correct sequence number – “hash” – that is specific to the given block, there is not much chance of finding it. Whoever solves the puzzle first, gets the opportunity to officially add a block of transactions to the ledger and get fresh and new coins as reward. The reward is given in whatever cryptocurrency’s blockchain miners are operating into. For example, BTC originally used to reward miners in 50 BTC, but after the first halving it decreased to 25 BTC, and at present time it is 6.25 BTC. The process of miners competing against each other in order to complete the transactions on the network and get rewarded is known as the Proof-of-Work (PoW) algorithm, which is natural for BTC and many other cryptocurrencies. Also there are another consensus mechanisms: Proof-of-Stake (PoS), Delegated Proof-of-Stake (dPoS), Proof-of-Authority (PoA), Byzantine Fault Tolerance (BFT), Practical Byzantine Fault Tolerance (pBFT), Federated Byzantine Agreement (FBA) and Delegated Byzantine Fault Tolerance (dBFT). Still, all of them are used to facilitate an agreement between network participants.
The way that system works – when many computers try to verify a block – guarantees that no computer is going to monopolize a cryptocurrency market. To ensure the competition stays fair, the puzzle becomes harder as more computers join in. Summing it up, let’s say that mining is responsible for two aspects of the crypto mechanism: producing the proof and allowing more coins to enter circulation.

Types of cryptocurrency

In the virtual currency world there are a bunch of different cryptocurrency types with their own distinctive features.
The first cryptocurrency is, of course, Bitcoin. Bitcoin is the first crypto coin ever created and used. BTC is the most liquid cryptocurrency in the market and has the highest market cap among all the cryptocurrencies.

Altcoins

The term ‘altcoins’ means ‘alternatives’ of Bitcoin. The first altcoin Namecoin was created in 2011 and later on hundreds of them appeared in crypto-world, among them are Ravencoin, Dogecoin, Litecoin, Syscoin etc. Altcoins were initially launched with a purpose to overcome Bitcoin’s weak points and become upgraded substitutes of Bitcoin. Altcoins usually stand an independent blockchain and have their own miners and wallets. Some altcoins actually have boosted features yet none of them gained popularity akin to Bitcoin. More about altcoins in our article.

Tokens

Token is a unit of account that is used to represent the digital balance of an asset. Basically tokens represent an asset or utility that usually are made on another blockchain. Tokens are registered in a database based on blockchain technology, and they are accessed through special applications using electronic signature schemes.
Tokens and cryptocurrencies are not the same thing. Let’s explain it more detailed:
• First of all, unlike cryptocurrencies, tokens can be issued and managed both centralized and decentralized.
• The verification of the token transactions can be conducted both centralized and decentralized, when cryptocurrencies’ verification is only decentralized.
• Tokens do not necessarily run their own blockchain, but for cryptocurrencies having their own blockchain is compulsory.
• Tokens’ prices can be affected by a vast range of factors such as demand and supply, tokens’ additional emission, or binding to other assets. On the other hand, the price of cryptocurrencies is completely regulated by the market.
Tokens can be:
• Utility tokens – something that accesses a user to a product or service and support dApps built on the blockchain.
• Governance tokens – fuel for voting systems executed on the blockchain.
• Transactional tokens – serve as a unit of accounts and used for trading.
• Security tokens – represent legal ownership of an asset, can be used in addition to or in place of a password.
Tokens are usually created through smart contracts and are often adapted to an ICO – initial coin offering, which is a means of crowdfunding. It is much easier to create tokens, that is why they make a majority of coins in existence. Altcoin and token blockchains work on the concept of smart contracts or decentralized applications, where the programmable, self-executing code is ruling the transactions within a blockchain. By the way, the vast majority of tokens were distributed on the Ethereum platform.

Forks

Generally a fork occurs when a protocol code, on which the blockchain is operating, is being changed, modified and updated by developers or users. Due to the changes, the blockchain splits into 2 paths: an old way of doing things and a new way. These changes may happen because: a disagreement between users and creators; a major hack, as it was with Ethereum; developers’ decision to fix errors and add new functionality. The blockchain mainly splits into hard forks and soft forks. Shortly speaking, coin hard forks cannot work with older versions while soft forks still can work with older versions.
Hard fork – after a hard fork, a new version is completely separated from the previous one, there’s no connection between them anymore, although the new version keeps the data of all the previous transactions but now on, each version will have its own transaction history. In order to use the new versions, every node has to upgrade their software. A hard fork requires majority support (or consensus) from coin holders with a connection to the coin network. If enough users don’t update then you will be unable to get a clean upgrade which could lead to a break in the blockchain.
Soft fork – a protocol change, but with backward compatibility. The rules of the network have been changed, but nodes running the old software will still be able to validate transactions, but those updated nodes won’t be able to mine new blocks. So to be used and useful, soft forks require the majority of the network’s hash power. Otherwise, they risk becoming set out and anyway ending up as a hard fork.

Stablecoins

As it comes from the name, stablecoins are price-stabilized that are becoming big in the crypto world. Still enjoying most of the “typical-cryptocurrency” benefits, it is standing out as a fixed and stable coin, not volatile at all. Stablecoins’ values are stabilized by pegging them to other assets such as the US Dollar or gold.
Stablecoins include Tether (USDT), Standard (PAX), Gemini Dollar (GUSD) which are backed by the US Dollar and approved by the New York State Department of Financial Services.

Conclusion

Now that we hacked into cryptocurrency, you probably understand that it is much less mysterious than it first seemed. Nowadays, cryptocurrencies are making the revolution of the financial institution. For example, Bitcoin is currently used in 96 countries and growing, with more than 12,000 transactions per hour. More and more investors are involved, banks and governments realize that these cutting edge technologies are prone to draw their control away. Cryptocurrencies are slowly changing the world and you can choose – either stand beside and observe or become part of history in the making.

Charles Hoskinson on the Rough Days - [Text Version]

https://preview.redd.it/h49t3t6u9pl51.png?width=1221&format=png&auto=webp&s=fde73f432fd15d2b361f4e1621e67785bc27e30e
We as AzureADA SPO watch all the videos by Charles Hoskinson. These videos are not only great news on Cardano development and ecosystem, but very often a source of inspiration. The video with the name “Rough Days” streamed live on September 4, 2020 is really a historical speech, that’s why we decided to transcribe for everyone who prefers to read rather than to watch and listen.
The video you can watch here: https://www.youtube.com/watch?v=qM192wAV4LA
And here is the text version.
Hi everybody
Charles Hoskinson here live from warm sunny Colorado. Always warm, always sunny, sometimes Colorado. And I got my Massey Ferguson hat on. Take that off, see my hair's all messed up. One of these days and we'll lose all that hair.
It’s a rough day today and that markets are terrible. down 20 percent for most people. And every now and then I talk about price, I rarely do, but in general, let's talk about the macro.
Crypto is a unique phenomenon, it's a unique thing and these are crazy times. I remember just a few months back when coronavirus first came out and we saw basically everything just bottom out, everybody went crazy they went to cash all asset classes just went to hell in a handbasket. And I did a video and I said: «Guys, our best days are ahead of us as an ecosystem and as an industry. And what happened? Everything got better over time. People started getting more optimistic. You know, the reality is that we are seeing an old industry die right now, the legacy financial system.
I just read Biden's tax plan. He wants to treat capital gains as ordinary income and put another 12,5% on top of that. And at the end of the day, all these new taxes amount to a trillion or so extra dollars, I think, per year in income. Takes six years from the make back what they printed out of thin air for coronavirus and are willing to print again. Which begs the question why do we even pay taxes anymore if we can just print money out of thin air. And we have a whole movement of people, the AOC crowd, wake up every day and they say: «Modern monetary theory: the actual supply doesn't matter. All that matters is how much can we print and get away with it."
This is where we're at as an economy right now. And globally speaking, a lot of other nations agree with this. So given that the whole world, the leadership of the world is talking about negative interest rates, they’re talking about predatory financial systems hyperinflation, just print money modern monetary theory, just print as much cash as you want. And we look to the cryptocurrency industry and, God, we got a lot of problems.
I think this collapse is probably because one of the most prominent exchanges in South Korea got hit. They got shut down by the South Korean government. They, at one time, were responsible for a big part of the kimchi premium. And you know what? Korean government might shut down a few more Korean exchanges. And usually the market base these things in. We got crazy yield farming weird stuff going on in the DeFi space. All these other local events and their blips, they don't really matter that much. Just like corona in the long term won’t matter too much. In terms of the markets what matters is the trend and where are we going.
I had a meeting with some people this morning and we talked about revolutionizing the healthcare industry and getting things better in terms of supply chains. I had another meeting with a soon-to-be former Wyoming state representative about how we're going to get governments to adopt blockchain technology. I talk every day to governors, heads of states congressmen, senators, mayors, some cities, sometimes very large cities with millions of people. They all say the same thing: «We need help, we need solutions, we’re damn tired of the way that the old system is running». And you know what? If we don't solve it - a lot of people are going to get hurt or continue to be hurt. The common theme that we all have is - no one's happy.
Look at the black lives matters protests. Taking their philosophy of the organization aside
the ranking file people are there not because they love marxism they're there because they're unhappy with the way society is. And why shouldn't they be?
When my grandfather got his first job on my mom's side out of the Korean war, he was a lineman. And he made enough money from that job to have seven kids and have his wife stay at home. No college degree fresh out of high school, fresh out of marine demolitions and alignment five boys and two girls. And he could take care of that family and save money every month, have a car and a house and that was his standard of living. How many people in the middle-class today in the United States or Europe for that matter have the ability on a single person’s salary to raise seven children and have the wife or the husband stay at home?
How many people? Not many. Why? Because our monetary system has failed us. The inflationary policy has created a situation where the Jeff Bezos can have 200 billion dollars and make windfall profits every year regardless of how bad the economy is and the everyday people they don't get a pay increase, so a lot of cases they don't get keep their job and their money deteriorates in value a lot more than three 3% per year.
Our industry has principles in that we worship the math and the protocols and the stable monetary policy, these types of things. And as corrupt as some of the exchanges can be and some of the bad actors are: all movements suffer from these warts. And they're finite and temporary. You run out of them at some point. Self-regulation kicks in or standards kick in and these bad actors flush out. And what's left behind is a crucible that contains the truth of the matter, which is: we're going to win as an industry.
There's just no doubt in my mind. You have bad days in the market, you have damn good days in the market. You get addicted to the good ones and you hate the bad ones but at the end of the day, it's only going in one direction which is: crypto is going to eat the world.
Every voting system, every property registration system, every monetary system the next 25 to 50 years is going to be running on the tech we build and others build. And running with the principles of power to the edges. This is the great challenge of our time: to do it in a way that it's fair, transparent, open, and doesn't allow a government to co-opt it. It's gonna be a lot of fights here the least of our concerns and matters are a red day. And every now and then I like making these videos to remind people why I’m here and why you should be here too. As toxic as the trolls could be and these other people can be - none of them really matter. Markets don’t really matter. What matters are the principles and the purpose behind what we do. And you have to ask yourself: - Are you happy with the way that society is? Are you happy with the money in your pocket? Are you happy with the political leadership representing your nations? Are you happy with your future and do you honestly believe if we keep doing the things that we did and continue to do that the future is going to be better? Or do you think it's going to be worse or stagnant?
I think too many people have woken up and they realize that if we continue doing the things that we do, the future is going to be a bad place. And they don't want that to happen. And so we're voting with our wallets, we’re voting with our feet and we as a collective industry are waking up and figuring out how to build something better. And there's some good days and bad days along the way. Today's a bad one, but there are going to be good days tomorrow. Just like I told you back when corona made everything go into free fall. And I told you before. And I warned you about with ICO mania. We're in a DeFi bubble right now. There’s no doubt in my mind about that. I saw it in 2017 with ICO mania, I see it here. And there's probably going to be worse days ahead in that respect. But the trend is always the same and never forget that. And never forget that real people are actually adopting these systems and using them. And every day we see more and more and every day that movement grows.
What's so humbling is that I know a lot of you are here with me. It used to be pretty lonely space to be in a few years back. You know, the conferences, they didn't have many people. My first bitcoin meetup group in 2011 in Colorado is at the gypsy house cafe, I think I was 13th in Pearl over Capitol hill in Denver. And I registered for the event, I showed up. Two people registered: myself and another
guy. And the other guy didn't show up so I had coffee with myself. Compare that with the Shelley summit that we had in July of 2020: 10 000 attendees. Ten thousands from all across the world. Compare that to where we are at today just nine years later. Pretty amazing if you think about how fast things have grown and how many fertile beautiful ideas exist in this industry and what this industry is doing for the world as a whole. And that is why we're going to win. Because at the end of the day who can argue against freedom? Who can argue against liberty? Who can argue against putting people in control? The only way you can is when you believe people are stupid, people are evil, people are incapable. And I suppose that's a philosophical difference between those who currently lead and the people who want to replace them.
The people in charge right now of the world, the big banks, the Fortune 500 companies, the media, Hollywood, these things - they're very cynical people who believe in the worst in us. They look at everyday people with sustain and disgust and say: «These people if left to their own devices will be chaos. These people if left to govern themselves will burn everything to the ground and destroy everything.». And every single time I have ever seen a bad event happen, what the news doesn’t show you and what those people don't talk about is how we come together and help each other out. Someone gets injured in the streets more often than not people show up and help them. People need a helping hand someone always shows up more often than not. And this is no different.
I don't believe the political process is effective anymore in any modern democracy. They've all been co-opted, perhaps they always were. But what I do believe is that we can come together and change things economically, which is what we're doing. And it's messy. Building our own money is messy, building our own industry is messy. We make a lot of mistakes along the way, we lose a lot along the way. We collect some scars too while we're at it. But progress every year keeps being made. The technology every year keeps getting better.
Today, right here, right now provably secure proof of stake protocols are in circulation. They were a fantasy five years ago, now they're a fact of life.
Today, right here, right now snarks have evolved by an order of magnitude in every category from validation time to efficiency to proof size. In all favorable ways which opens up all kinds of new applications and scalability and privacy.
Today, right here, right now layer 2 protocols are more advanced than they have ever been in our industry's history. giving us the ability to build payment systems that scale to billions of people.
Today, right here, right now we are seeing massive innovations in governance and a fertile environment for things like approval voting, threshold voting, preference voting, quadratic voting that will enable us to build all kinds of new treasuries and governance systems that eventually will scale to nation-states.
As the politicians of today argue whether the post office can properly count paper ballots that people mail, we are building voting systems with state-of-the-art cryptography living on phones where you can vote with just a tap of a button and enjoy more security than we have ever imagined before.
That is the future. This movement is enabling humanity. Money flowing at the speed of thought and the speed of thought making new money.
How can you compete with that? You can’t, unless you bring people down with cynicism and disdain. And ultimately what competing vision do they offer? That you all should be in chains.
That we should just be wage slaves. We should just accept that every year our money deteriorates in value. That we should just accept that the rich will get richer the poor get poorer. And every now and then they throw us table scraps. And when we get real angry - they usurp the movements and then install their own leadership to basically take those movements from us. As we've seen so many times before and we will see it again.
I'm sorry that's not a road I want to walk down. And I'm willing to ride rocky waters, crazy markets crazy people in unlimited flood and trolling. But I will never apologize for believing in the best in people. And I will never apologize for believing that if only we give everyone around us the tools to save themselves and society that they can do it. They don't need great leaders and charisma. No one needs someone to tell them what to do. We all know what to do. We all know how to make the world a better place. We just have to be trusted enough to do it ourselves.
You know what? For the first time ever we did with Bitcoin. And then we did it again with Ethereum. And now we're doing it again with Cardano. And we, as a movement, will continue to do it.
So I believe our best days are ahead of us and every day I wake up and there's more people marching with me in that respect. And one day it'll be millions. And one day it'll be billions. And one day all those cynics will be gone. Replaced with optimists who once again believe that tomorrow is going to be better than today. and that we're going to leave the world just a little bit better than the way we found it.
So every now and then on a tough day I like making a little message and letting you guys all know it's going to be better and you know what it will be. Just have to have faith that it will be. So hold the line, hold strong, and have faith in each other and go do something. Build something. Start something. Got a lot of podcasts on the way. A lot of things coming down the pipe for the DC fund. A lot of opportunities to actually innovate. Multi-assets are coming soon. Plutus is coming soon. Guys are going to be able to build a lot.
Start thinking today what's the business plan. What would you like to change? Small or large. You don't complain about voting - change voting! Your own organization. Maybe you belong to a club - do a blockchain-based voting system. Maybe you have some political influence. Have a primary democrat or republican or your local primary in your country for selecting candidates done with blockchain-based voting. Maybe you want to build a new financial product. Think about it! Figure it out! There's so much there! It’s all there! It's ready to go, it's for you to take and build and innovate with.
Every day I wake up I try to make the platforms better. I try to push the technology a little further along. I try to hire great people and bring them into our industry. Cardano brought the Haskell industry into the cryptocurrency space. Cardano brought a lot of academics, who had never thought about cryptocurrencies, into the cryptocurrency space and we made our problems their problems and as a consequence, they started solving them in ways we could have never done before.
But most importantly Cardano brought a lot of YOU into the cryptocurrency space and you never thought you'd have this level of control and freedom over the fabric of society in the direction of the human race. Don't let that slip through your fingers. Figure out what you want to do with that superpower. Might be small, might be big. I dreamed big. You can dream big too. Even if you want to just dream small: every person counts every action counts. Up to the hill. Y'all matter. To me and to each other and we're all in this together. Never forget that. So, hard day, rough day. Tomorrow will be a better one. The day after will even be better.
See you guys soon
Take care!

From Conspiracy to Fact: An analysis of the COVID-19 Pandemic, Information Control, and the New World Order (Appendix includes hundreds of citations) - PART 1

UPDATE: This article is now available as a printable PDF with embedded hyperlinks for navigation through sources. This link will be valid thru July 9: https://ufile.io/4mpkg4x6

PLEASE NOTE: This article may be updated periodically with new information and links as they become available. All referenced information and a whole lot more is indexed and linked in the related appendix posts. Please feel free to crosspost, share, and take from my ideas to build your own. Namaste.
Part 1 | Part 2 | Appendix A | Appendix B

Hello. My name is Chris. I am nobody, really. An average citizen. I am an overweight 42 year old white male from the Midwestern suburbs of the US who has been fortunate enough to live a pretty comfortable life. I used to be a freelance graphic designer with a focus on small businesses, but I'm coming to terms with the fact that that career and part of my life is more than likely over in light of current events. Oh well, it was fun while it lasted.
I've always been concerned about social injustice and tried to stay politically informed, even dabbling in some activism here and there. At times I've stepped away from paying attention for my own mental health, or due to laziness, defeatism, whatever. But I've never stopped caring, or trying, to fight the good fight and do the right thing.
The news recently has of course swept us all up, and touched all our lives in some way or another. The world has never seen anything like the "Coronavirus Pandemic," and it's clear that our society will be changed forever when we finally come out the other end of this mess. But I've had the luxury of time recently, and in reading the news about things that were going on, I couldn't help but notice the patterns, and that a lot of stuff didn't exactly make sense.
So, here we go, with the "conspiracy theory."
I hate that term, because although it's technically accurate, it's been demonized and weaponized by the media and society at large to take on a bad connotation. Tinfoil hats, alien abductions, crazy people muttering to themselves, etc. You've no doubt got a lot of images in your mind of a conspiracy theorist.
And make no mistake, what I'm going to tell you here is all currently very popular conspiracy theory. However, I think that by removing opinions and conjecture from it, and focusing on facts and things that have already happened, I can present this huge amount of overwhelming, disparate information in a way that makes it less a "theory" and more a "research project." And so that is how I have approached this.
I have spent the last week doing little else besides reading every news and opinion article I could find, saving and organizing hundreds of links, and assembling a coherent, logical outline to organize and present these theories, and more importantly, facts. There are a lot of less-than-reputable sites and publications out there, and I have tried when at all possible to provide sources from verifiable news sites, with a wide range of slants and focuses, to illustrate that what is happening is not part of any one particular political agenda.
I hope that you take the time to check the links, really look into the information presented here, and form your own opinions. Please do not just take my word for it. To that end, there are also a few links mixed in that are labeled as having come from conspiracy. These are well-written and well-reasoned posts from other concerned citizens that I think are worth reading, and relevant to the discussion here.
One last thing - If you are new to most of these ideas, the information presented here is more than likely going to seem overwhelming at first. I encourage you now, and always, to take mental health breaks for yourself, and put down your phone or turn off your computer. The information will be here when you come back. And as you'll soon understand, what is happening is an unstoppable tide, truly a force of nature at this point, and there is nothing you can do to fight it, so try your hardest to relax, put on some chill music, hug your dog, and most of all...
BREATHE.
- - - - - - - - - - - - - - - - - - - - -
If you start researching conspiracy theory, you're going to find a lot of information. Some much better or worse presented than others, and some much more plausible or unbelievable than others. Despite the seeming ridiculousness of some things you might read, I encourage you to always approach new information with an open mind.
That said though, I have one main principle that guides all my beliefs about conspiracy theories, and that is the "Filter of Likelihood." Essentially, you have to ask yourself how possible, how likely, and how feasible a piece of information is. Furthermore, you need to ask yourself what the motivation would be. In many cases, it's quite easy to see how something makes a lot of sense based on other known info, whereas some theories seem rather implausible no matter how you look at it.
I am interested only in the plausible, and where possible, the already actualized. Additionally, there's a lot to be said, and a lot that has already been written on many of these topics, so I will focus on current events and simple concepts.
I will also ask you to open your mind to possibility. Please consider this as you evaluate new information:
  1. Do you believe there are things going on in the world that you don't know about yet?
  2. Do you believe that there is technology and science you've never heard of?
  3. Do you believe that society is progressing at an increasing rate?
  4. Do you believe that as populations grow, we require new societal strategies?
  5. Do you believe that those with power and money want to retain their power and money?
Of course you believe all these things, and none of these are wild or unusual concepts. Rather, these are very basic concepts that apply to everyone, and always have. They are all part of our shared human experience, and undeniable facts of life. Populations grow, societies evolve, technology advances, and the world changes. And most important to our discussion here, people, families, and empires constantly jockey for power and control, while fighting for resources, power, fame, and...
MONEY.
We all hate TicketMaster, right? Who do they think they are, what the hell is this bullshit "service fee," etc. It's something everyone can get behind. But did you know that TicketMaster willingly cultivates that image? That venues, teams, and artists, in their pursuit of more money, raise fees and then let TicketMaster be the bad guy and take the heat so their reputations remain intact?
There are many more people, organizations, and other entities in the world playing that same role for those who really have the money, who really call the shots. And those who call the shots work very hard and spend absolutely unfathomable amounts of money, time, and blood, to make sure that you don't ever realize who's actually taking your money.
They do this in the simplest, easiest way. If you simply control information from the top down, and disseminate it when and where you see fit, you can effect great societal change without lifting a finger.
Please imagine... really, try to imagine... You just read an article, saw a video, whatever, from a very, very reputable source. And it just informed you that an asteroid was 83% likely to impact the Earth next month. What would you do? What would happen in the world?
Hopefully an asteroid will not hit next month, but it's important to really imagine what would happen and why, and how. Because a huge amount of information would be generated and published, people would panic, society would crumble, and the world as you know it would change forever in an instant, the moment you read that headline.
Control of information is one of the most powerful tools known to mankind today. A person living in 2020 can easily encounter as much information in a day as someone in Medieval times might have encountered in a lifetime. And it comes at you from all angles, in all forms, non-stop, 24/7. Much like the water in the pipe, the information is always there, and one needs but turn it on.
Disseminating the information then becomes a practice all its own, and to be sure, information processing accounts for more than half of the US GDP. And the rate at which it's spread, and way it is handled makes a huge difference in the societal repercussions. So a few different techniques are used:
It might be the greatest understatement of all time to say that there has been a lot of information passed around about COVID-19, the "Coronavirus," recently. In fact, there has never been anything like what we are currently experiencing in all of human history, and not by a long shot. And this unprecedented turn of events has caused a lot of people to react in a lot of ways, and say and do a lot of things, for better or for worse.
Full disclosure: In particular, if you look up conspiracy theory, you'll see a lot of stuff suggesting that the "Coronavirus is a hoax." (You'll also find a lot of poorly-written rambling) I want to be clear that I DO NOT believe that. I am 100% sure that there is a Coronavirus, that it is making people sick, that a lot of people are dying, and that our medical professionals and many other undervalued workers are overwhelmed, and breaking their backs every day to do their best to keep their friends, families, and loved ones safe. I am extraordinarily grateful for them and admire the resolve and bravery that so many have shown in the face of this disaster. I do not think it is a hoax at all.
However, I think that literally everything else that is happening surrounding the "pandemic" is.
- - - - - - - - - - - - - - - - - - - - -
The Pandemic
In the first week of January this year, I got sick. Really sick. I know when I got it and who I got it from, and honestly the exact moment I got it (I only was in proximity of the dude for a few minutes). He had warned me that he was really sick, and I blew it off. I started feeling sick a day or two later, and a day or two after that I felt like I was dying. Fever, chills, aches, extraordinary fatigue. And literal, nonstop, 24/7 coughing. I had every single symptom of what we now know as COVID-19. I commented to anyone who would listen that I didn't recall ever feeling that sick before in my entire life. The most memorable part of it though was that after a couple days, I completely lost my sense of smell and taste. Joked a lot about how you could feed me onions and soap cause I'd have no idea. I try to have a good attitude about being sick.
I spent a week sleeping on the couch before I finally went to the doctor. She gave me a Prednisolone steroid pack (which has worked well for me in the past), some Trazodone to knock me out, and Benzonatotate for my cough. As soon as I took the first dose of steroids I started to feel pretty fucking great, and it was more or less a non-issue after that.
I spoke to a lot of people about it then and after, and man, I can't tell you how many stories I personally heard from people I know that said the exact same thing. Then I started reading the same story over and over again on Reddit:
We didn't start really hearing about the Coronavirus in the media until the beginning of March, and we didn't hear about the "Pandemic" until just a couple weeks ago. And what a couple weeks it's been since then. But I am quite certain that it's been around for a lot longer and that I, and a lot of other people I know, had it - and DID NOT DIE FROM IT - way back in January.
We now know that the first documented case in the US was on January 19th, but that word "documented" is so, so important here. That means that we had identified the virus, developed a test, and tested a person with the symptoms that day. It does NOT mean that was when the virus reached the United States. How sick do you have to be before you take a day off work? Before you go to the doctor? With America's healthcare system or lack thereof, it's almost certain that many people had this virus before we determined what it was, and how infectious it really was.
There is also the matter of the statistics of severity vs the regular flu. This is a highly contentious topic and I am no medical expert, and do not wish to make any assertions. However, what I can tell you from my personal experience is this: I had a horrible "flu" in January, got basic medicine, got better. So, either I had the flu, or perhaps I did indeed have the Coronavirus.
We will never know because I was never tested. But the important thing is that it doesn't matter. Either I (and many others) had the Coronavirus and it did not kill us (calling into question the severity of the infection) or we just had a bad cold or flu, but it had the exact same symptoms as COVID-19 (calling into question the extent of Coronavirus diagnoses). But logically, one of those two statements is true.
Furthermore, the data keeps changing, and I don't mean increasing on a daily basis. I mean up and down, back and forth, it is deadly or maybe it isn't, etc. On January 14 the WHO told you it couldn't spread from human to human. But then on Jan 19 we saw the first case of Coronavirus in the United States. Then it turns out that the Wuhan market outbreak began earlier in December. And then it's an "epidemic," but most people will only get mild symptoms. What are you supposed to believe? And it sure does seem to come at you as a firehose, and it's hard to even think about anything because OHMYGODTHECORONAVIRUS!
But let's stop and look a couple basic facts. As a matter of fact, I'm going to let Dr. Sucharit Bhakdi explain this one to you. This is a very informative 10 minute video, watch it:
Sucharit Bhakdi - Very clear math showing that the COVID statistics are being manipulated
So 80% of people only experience mild symptoms, and we're crashing the economy for this? The statistics aren't any more extreme than many other illnesses we've had over time, and we're crashing the economy for this? It doesn't make sense until you consider that there are other factors besides just the virus at play.
Wolfgang Wodard - Explaining how the statistics are being manipulated to cause panic
The media, and society at large is inundating you with terrifying information about the Coronavirus. But if it's not as bad as we originally thought, then why? We don't freak out about every illness that comes along, and we've certainly never in the history of civilization had over 1/3 of the global population locked down under mandatory quarantine.
And then there's the debate about where the virus came from. We believe it came from a meat market in China, under unsanitary conditions. The science behind a coronavirus making the leap from one species to another is well-established and researched, and it is a very likely scenario. There are also conspiracy theories that state that China released it on its people intentionally, or even that the US military released it in China. Again, we will never know exactly where this Coronavirus came from. It may be natural, it may be man made, and there are very plausible paths for both. I don't know what to believe myself. So here I ask you to make your own judgement based on likelihood.
What we do know though is that the state of the world this virus has been unleashed on has played a major factor in its spread. In 1950 the global population was 2.5 billion, and that has exploded to almost 8 billion people in 2020. As a matter of fact, population growth has been exponential since about the time of the Industrial Revolution.
With all these people on the planet there are sure to be many disagreements and conflicts, and there indeed have been. As a matter of fact, 2019 saw global protests on an unprecedented scale, in Hong Kong, France, Syria, and many other countries. Citizens have literally been fighting police and military with rocks, clubs, arrows, and molotov cocktails.
Did you know that? Despite my seeing headlines and pictures every day of the riots in Hong Kong, I have been shocked to learn that multiple of my close friends, intelligent and aware people, had no knowledge whatsoever of the protests even existing. But that is far from a coincidence; rather, it is quite by design.

Billionaires and Coincidences
Another major talking point over the last 5 to 10 years has been the "1%" - the handful of super-rich individuals who posess and control the vast majority of the Earth's wealth and resources. Where it used to just be a numerical term, "Billionaire" is now a dirty word, and one of the nastiest. We all hate billionaires. They are evil, and profit off the exploitation of the rest of the world.
The "Illuminati" we call them, in pursuit of a "New World Order." Crazy stuff, right? Mysterious symbols and people in black robes doing nefarious things in secret meetings, and running the world from behind the scenes. We love the Illuminati, it's a huge pop culture thing now. The subject of endless speculation, they are made fun of in the media, movies, and now Taco Bell commercials. It's so far fetched it could never really be true. And the fact that you think that is by design as well.
So, we don't know where the Coronavirus came from, but it's certainly here, and there are lot of other things unfolding in the world around it. Many different current events from all different places and fields of study. Some of it seems a little too coincidental. It is certainly very coincidental that this economically destructive Coronavirus entered the world right as there were global uprisings, protests in the street, and a growing public hatred for billionaires.
Well, here are a few other coincidences: Hundreds of CEOs of major companies stepped down from their positions in recent months. Multiple US Senators sold stock right before the market crashed. Even the boss of the New York Stock Exchange sold his own stock right before the crash. Did they know something they weren't telling us?
Here's another coincidence. In 2010, The Rockefeller Foundation published a selection of future-predicting scenarios in the name of "exploring the ways that technology and development could co-evolve." One of these four scenarios, entitled "Lock Step," eerily predicts a global viral pandemic and the resulting hypothetical consequences, which almost exactly mirrors the COVID-19 pandemic we are in the midst of today.
Also coincidental: The first case of COVID-19 was diagnosed in China on November 17th, 2019. Literally one month earlier, The Johns Hopkins Center for Health Security in partnership with the World Economic Forum and the Bill and Melinda Gates Foundation hosted Event 201, a high-level pandemic exercise on October 18, 2019, in New York, NY. In this exercise, they discuss the potential implications and consequences of a novel Coronavirus, including an economic crash, martial law, and of particular interest, the control of information. (You can view some published highlights here)
The World Economic Forum is comprised of the richest of the rich. The 1%. The Billionaires. CEO's, politicians, business owners, and many other powerful and influential figures. They meet regularly to discuss topics of global concern, and strongly control the dissemination of information. And of primary concern to many of them is maintaining their wealth and power in a rapidly-changing world.
And finally, here's one more coincidence: At the exact same time as the Event 201 exercise, The World Military Games was held in Wuhan, China, Oct 18-27, 2019. It was the largest military sports event ever to be held in China, with nearly 10,000 athletes from over 100 countries competing in 27 sports. Wuhan China was, as we now believe, the source of our current global COVID-19 outbreak.
Whether you think it is a "conspiracy" or not, that is all certainly coincidental, to say the least.
- - - - - - - - - - - - - - - - - - - - -
"Why didn't I hear about any of this?"
That's an excellent question, and one that likely has multiple answers. For starters, how much do you really pay attention? Where do you get your news from? Do you research things you hear or just accept them on hearsay? Critical thinking skills are paramount in making sense of the chaos unfolding all around us.
As I mentioned before, I can tell you that I personally know multiple people who had no clue whatsoever about the riots in Hong Kong last year. As you read this, you may be one of them. And it may seem like something that is happening far away, and "could never happen here." Or you may have been aware of it but just that it was happening. But please, consider for a moment: millions of average citizens risked their lives and safety in the streets of Hong Kong for months on end, fighting police and military, and transforming the city they lived in into a warzone. WHY? Why would people do something like that? Regardless of their motivations, that many people were banding together to fight for something they believed in. And that is worth considering.
It's not really your fault though that you may not catch wind of all this news. The "mainstream media" that you hear about all the time deliberately controls information - downplaying threats and overreacting to silly things - in order to make sure that you hear the version of the news that they want you to hear.
Did you know that only 6 corporations control 90% of the media In America? That number is reduced from 50 companies in the 80's. And literally all the news you see on TV, at the very least, is 100% owned and controlled by these companies. Lately, distrust is growing for cable news networks, and many people turn to their local hometown station for trusted news. The problem with that though is that your hometown station is probably owned by Sinclair Media, one of the most powerful broadcast networks in the country that you've never heard of.
Please watch this very brief video, illustrating the chokehold that Sinclair Media maintains over your nightly local news broadcast: https://www.youtube.com/watch?v=hWLjYJ4BzvI
Of course, not every piece of news is pre-programmed but a lot is. The real news is out there, but sometimes you have to look a little deeper than the infographics on TV news. Even if information is being directed from the top down, the boots on the ground tend to be passionate people with a variety of interests and agendas, and they are still doing their best to do real journalism despite corporate oversight.
Think of those who are directing the information as steering an impossibly massive ship with a rudder. You can slowly adjust the course of direction, however it is slow to react. If you want to stop, you have to start thinking about stopping wayyy ahead of time. And similarly, once it gets underway, it is then influenced by an inertia all its own. Micro controls and adjustments aren't really possible.
Our society is this giant ship. There are 8 billion people on this earth - that is 8000 million. An incomprehensible number that grows rapidly every day. As civilization grows and advances, so does our medicine, our technology, our cultural norms. These are all natural processes that are necessary to manage an increasing number of societies all around the globe. And many of the advances we're making have exciting potential benefits for humanity, although as with all tools, they also inherently possess the potential for abuse.
Here are some other things happening in society right now, some you may be aware of and many you may not:
There is an interesting chicken or egg relationship between science fiction and real world science. Sci-fi writers are inspired by the real science of the day, then they apply their creativity to imagine what might be in the future. Young scientists encounter these fantastical ideas and think they are worth pursuing, and then set about to make them a reality, and the cycle continues.
Futuristic concepts are then preempted and introduced through the media to the conscious mind, as we include them in books, movies, TV, video games, and more. Eventually we start seeing headlines of these new technologies and developments happening in other places, usually Japan and China first due to their prevalence in the industrial and technological sectors of our global economy.

Cryptography: How Bitcoin Works? Andrew Poelstra on Bitcoin Math & Research Crypto Math - YouTube The Math Behind Bitcoin Bitcoin 101 Elliptic Curve Cryptography Part 5 The Magic of Signing & Verifying

The math behind RSA Cryptography uses very large numbers. Usually the primes chosen are hundreds of digits long. You will use much smaller primes in thismodule. Even small primes are too large to calculate the math for. All the math is done in mod. Mod is a concept you may not be familiar with. It means that youalways take your answer, divide it by a number, and keep the remainder as your ... What is the math behind elliptic curve cryptography? Originally published by Hans Knutson on April 6th 2018 55,692 reads @knutson.hansHans Knutson. Introduction. When someone sends bitcoin to you, they send the bitcoin to your address. If you want to spend any of the bitcoin that is sent to your address, you create a transaction and specify where your bitcoin ought to go. Such a transaction ... Bitcoin does this using something called ‘elliptic curve cryptography’ to ensure the security of transactions between owners of Bitcoins. Elliptic curve cryptography is a type of public key cryptography, relying on mathematics to ensure that a transaction can be secure. Read more about elliptic curve cryptography.
