A Detailed Summary of Every Single Reason Why I am Bullish on Ethereum

The following will be a list of the many reasons why I hold and am extremely bullish on ETH.

This is an extremely long post. If you just want the hopium without the detail, read the TL;DR at the bottom.

ETH 2.0

As we all know, ETH 2.0 phase 0 is right around the corner. This will lock up ETH and stakers will earn interest on their ETH in return for securing the network. Next comes phase 1 where the ETH 2 shards are introduced, shards are essentially parallel blockchains which are each responsible for a different part of Ethereum’s workload, think of it like a multi-core processor vs a single core processor. During phase 1, these shards will only act as data availability layers and won’t actually process transactions yet. However, their data can be utilised by the L2 scaling solution, rollups, increasing Ethereum’s throughput in transactions per second up to 100,000 TPS.
After phase 1 comes phase 1.5 which will move the ETH 1.0 chain into an ETH 2 shard and Ethereum will be fully secured by proof of stake. This means that ETH issuance will drop from around 5% per year to less than 1% and with EIP-1559, ETH might become a deflationary asset, but more on that later.
Finally, with ETH 2.0 phase two, each shard will be fully functional chains. With 64 of them, we can expect the base layer of Ethereum to scale around 64x, not including the massive scaling which comes from layer 2 scaling solutions like rollups as previously mentioned.
While the scaling benefits and ETH issuance reduction which comes with ETH 2.0 will be massive, they aren’t the only benefits. We also get benefits such as increased security from PoS compared to PoW, a huge energy efficiency improvement due to the removal of PoW and also the addition of eWASM which will allow contracts to be programmed in a wide range of programming languages, opening the floodgates for millions of web devs who want to be involved in Ethereum but don’t know Ethereum’s programming language, Solidity.

EIP-1559 and ETH scarcity

As I covered in a previous post of mine, ETH doesn’t have a supply cap like Bitcoin. Instead, it has a monetary policy of “minimum viable issuance”, not only is this is a good thing for network security, but with the addition of EIP-1559, it leaves the door open to the possibility of ETH issuance going negative. In short, EIP-1559 changes the fee market to make transaction prices more efficient (helping to alleviate high gas fees!) by burning a variable base fee which changes based on network usage demand rather than using a highest bidder market where miners simply include who pays them the most. This will result in most of the ETH being paid in transaction fees being burned. As of late, the amount which would be burned if EIP-1559 was in Ethereum right now would make ETH a deflationary asset!

Layer 2 Scaling

In the mean time while we are waiting for ETH 2.0, layer 2 scaling is here. Right now, projects such as Deversifi or Loopring utilise rollups to scale to thousands of tx/s on their decentralised exchange platforms or HoneySwap which uses xDai to offer a more scalable alternative to UniSwap. Speaking of which, big DeFi players like UniSwap and Synthetix are actively looking into using optimistic rollups to scale while maintaining composability between DeFi platforms. The most bullish thing about L2 scaling is all of the variety of options. Here’s a non exhaustive list of Ethereum L2 scaling solutions: - Aztec protocol (L2 scaling + privacy!) - ZKSync - Loopring - Raiden - Arbitrum Rollups - xDai - OMGNetwork - Matic - FuelLabs - Starkware - Optimism - Celer Network - + Many more

DeFi and Composability

If you’re reading this, I am sure you are aware of the phenomena which is Decentralised Finance (DeFi or more accurately, open finance). Ethereum is the first platform to offer permissionless and immutable financial services which when interacting with each other, lead to unprecedented composability and innovation in financial applications. A whole new world of possibilities are opening up thanks to this composability as it allows anyone to take existing pieces of open source code from other DeFi projects, put them together like lego pieces (hence the term money legos) and create something the world has never seen before. None of this was possible before Ethereum because typically financial services are heavily regulated and FinTech is usually proprietary software, so you don’t have any open source lego bricks to build off and you have to build everything you need from scratch. That is if what you want to do is even legal for a centralised institution!
Oh, and if you think that DeFi was just a fad and the bubble has popped, guess again! Total value locked in DeFi is currently at an all time high. Don’t believe me? Find out for yourself on the DeFi Pulse website.

NFTs and tokeniation

NFTs or “Non-Fungible Tokens” - despite the name which may confuse a layman - are a basic concept. They are unique tokens with their own unique attributes. This allows you to create digital art, human readable names for your ETH address (see ENS names and unstoppable domains), breedable virtual collectible creatures like crypto kitties, ownable in game assets like Gods Unchained cards or best of all in my opinion, tokenised ownership of real world assets which can even be split into pieces (this doesn’t necessarily require an NFT. Fungible tokens can be/are used for some of the following use cases). This could be tokenised ownership of real estate (see RealT), tokenised ownership of stocks, bonds and other financial assets (which by the way makes them tradable 24/7 and divisible unlike through the traditional system) or even tokenised ownership of the future income of a celebrity or athlete (see when NBA player Spencer Dinwiddie tokenized his own NBA contract.)

Institutional Adoption

Ethereum is by far the most widely adopted blockchain by enterprises. Ethereum’s Enterprise Ethereum Alliance (EEA) is the largest blockchain-enterprise partnership program and Ethereum is by far the most frequently leveraged blockchain for proof of concepts and innovation in the blockchain space by enterprises. Meanwhile, there are protocols like the Baseline protocol which is a shared framework which allows enterprises to use Ethereum as a common frame of reference and a base settlement layer without having to give up privacy when settling on the public Ethereum mainnet. This framework makes adopting Ethereum much easier for other enterprises.

Institutional Investment

One of Bitcoin’s biggest things it has going for it right now is the growing institutional investment. In case you were wondering, Ethereum has this too! Grayscale offers investment in the cryptocurrency space for financial institutions and their Ethereum fund has already locked up more than 2% of the total supply of ETH. Not only this, but as businesses transact on Ethereum and better understand it, not only will they buy up ETH to pay for their transactions, but they will also realise that much like Bitcoin, Ethereum is a scarce asset. Better yet, a scarce asset which offers yield. As a result, I expect to see companies having ETH holdings become the norm just like how Bitcoin is becoming more widespread on companies’ balance sheets.

The state of global markets

With asset prices in almost every asset class at or near all-time highs and interest rates lower than ever and even negative in some cases, there really aren’t many good opportunities in the traditional financial system right now. Enter crypto - clearly the next evolution of financial services (as I explained in the section on DeFi earlier in this post), with scarce assets built in at the protocol layer, buying BTC or ETH is a lot like buying shares in TCP/IP in 1990 (that is if the underlying protocols of the internet could be invested in which they couldn’t). Best of all, major cryptos are down from their all-time highs anywhere between 35% for BTC or 70% for ETH and much more for many altcoins. This means that they can significantly appreciate in value before entering uncharted, speculative bubble territory.
While of course we could fall dramatically at any moment in the current macro financial conditions, as a longer term play, crypto is very alluring. The existing financial system has shown that it is in dire need of replacing and the potential replacement has started rearing its head in the form of crypto and DeFi.

Improvements in user onboarding and abstracting away complexity

Ethereum has started making huge leaps forward in terms of usability for the end user. We now have ENS names and unstoppable domains which allow you to send ETH to yournamehere.ETH or TrickyTroll.crypto (I don’t actually have that domain, that’s just an example). No longer do you have to check every character of your ugly hexadecimal 0x43AB96D… ETH address to ensure you’re sending your ETH to the right person. We also have smart contract wallets like Argent wallet or the Gnosis safe. These allow for users to access their wallets and interact with DeFi self-custodially from an app on their phone without having to record a private key or recovery phrase. Instead, they offer social recovery and their UI is straight forward enough for anyone who uses a smart phone to understand. Finally, for the more experienced users, DApps like Uniswap have pretty, super easy to use graphical user interfaces and can be used by anyone who knows how to run and use a browser extension like Metamask.

The lack of an obvious #1 ETH killer

One of Ethereum’s biggest threats is for it to be overthrown by a so-called “Ethereum killer” blockchain which claims to do everything Ethereum can do and sometimes more. While there are competitors which are each formidable to a certain extent such as Polkadot, Cardano and EOS, each have their own weaknesses. For example, Polkadot and Cardano are not fully operational yet and EOS is much more centralised than Ethereum. As a result, none of these competitors have any significant network effects just yet relative to the behemoth which is Ethereum. This doesn’t mean that these projects aren’t a threat. In fact, I am sure that projects like Polkadot (which is more focused on complimenting Ethereum than killing it) will take a slice out of Ethereum’s pie. However, I am still very confident that Ethereum will remain on top due to the lack of a clear number 2 smart contract platform. Since none of these ETH killers stands out as the second place smart contract platform, it makes it much harder for one project to create a network effect which even begins to threaten Ethereum’s dominance. This leads me onto my next reason - network effects.

Network effects

This is another topic which I made a previous post on. The network effect is why Bitcoin is still the number one cryptocurrency and by such a long way. Bitcoin is not the most technologically advanced cryptocurrency. However, it has the most widespread name recognition and the most adoption in most metrics (ETH beats in in some metrics these days). The network effect is also why most people use Zoom and Facebook messengeWhatsApp despite the existence of free, private, end to end encrypted alternatives which have all the same features (Jitsi for the zoom alternative and Signal for the private messenger app. I highly recommend both. Let’s get their network effects going!). It is the same for Bitcoin. People don’t want to have to learn about or set up a wallet for alternative options. People like what is familiar and what other people use. Nobody wants to be “that guy” who makes you download yet another app and account you have to remember the password/private key for. In the same way, Enterprises don’t want to have to create a bridge between their existing systems and a dozen different blockchains. Developers don’t want to have to create DeFi money legos from scratch on a new chain if they can just plug in to existing services like Uniswap. Likewise, users don’t want to have to download another browser extension to use DApps on another chain if they already use Ethereum. I know personally I have refrained from investing in altcoins because I would have to install another app on my hardware wallet or remember another recovery phrase.
Overthrowing Ethereum’s network effect is one hell of a big task these days. Time is running out for the ETH killers.

Ethereum is the most decentralised and provably neutral smart contract platform

Ethereum is also arguably the most decentralised and provably neutral smart contract platform (except for maybe Ethereum Classic on the neutrality part). Unlike some smart contract platforms, you can’t round up everyone at the Ethereum Foundation or any select group of people and expect to be able to stop the network. Not only this, but the Ethereum foundation doesn’t have the ability to print more ETH or push through changes as they wish like some people would lead you on to believe. The community would reject detrimental EIPs and hard fork. Ever since the DAO hack, the Ethereum community has made it clear that it will not accept EIPs which attempt to roll back the chain even to recover hacked funds (see EIP-999).
Even if governments around the world wanted to censor the Ethereum blockchain, under ETH 2.0’s proof of stake, it would be incredibly costly and would require a double digit percentage of the total ETH supply, much of which would be slashed (meaning they would lose it) as punishment for running dishonest validator nodes. This means that unlike with proof of work where a 51% attacker can keep attacking the network, under proof of stake, an attacker can only perform the attack a couple of times before they lose all of their ETH. This makes attacks much less financially viable than it is on proof of work chains. Network security is much more than what I laid out above and I am far from an expert but the improved resistance to 51% attacks which PoS provides is significant.
Finally, with the US dollar looking like it will lose its reserve currency status and the existing wire transfer system being outdated, superpowers like China won’t want to use US systems and the US won’t want to use a Chinese system. Enter Ethereum, the provably neutral settlement layer where the USA and China don’t have to trust each other or each other’s banks because they can trust Ethereum. While it may sound like a long shot, it does make sense if Ethereum hits a multi-trillion dollar market cap that it is the most secure and neutral way to transfer value between these adversaries. Not to mention if much of the world’s commerce were to be settled in the same place - on Ethereum - then it would make sense for governments to settle on the same platform.

ETH distribution is decentralised

Thanks to over 5 years of proof of work - a system where miners have to sell newly minted ETH to pay for electricity costs - newly mined ETH has found its way into the hands of everyday people who buy ETH off miners selling on exchnages. As pointed out by u/AdamSC1 in his analysis of the top 10K ETH addresses (I highly recommend reading this if you haven’t already), the distribution of ETH is actually slightly more decentralised than Bitcoin with the top 10,000 ETH wallets holding 56.70% of ETH supply compared to the top 10,000 Bitcoin wallets which hold 57.44% of the Bitcoin supply. This decentralised distribution means that the introduction of staking won’t centralise ETH in the hands of a few wallets who could then control the network. This is an advantage for ETH which many proof of stake ETH killers will never have as they never used PoW to distribute funds widely throughout the community and these ETH killers often did funding rounds giving large numbers of tokens to VC investors.

The community

Finally, while I may be biased, I think that Ethereum has the friendliest community. Anecdotally, I find that the Ethereum developer community is full of forward thinking people who want to make the world a better place and build a better future, many of whom are altruistic and don’t always act in their best interests. Compare this to the much more conservative, “at least we’re safe while the world burns” attitude which many Bitcoiners have. I don’t want to generalise too much here as the Bitcoin community is great too and there are some wonderful people there. But the difference is clear if you compare the daily discussion of Bitcoin to the incredibly helpful and welcoming daily discussion of EthFinance who will happily answer your noob questions without calling you an idiot and telling you to do you own research (there are plenty more examples in any of the daily threads). Or the very helpful folks over at EthStaker who will go out of their way to help you set up an ETH 2.0 staking node on the testnets (Shoutout to u/superphiz who does a lot of work over in that sub!). Don’t believe me? Head over to those subs and see for yourself.
Please don’t hate on me if you disagree about which project has the best community, it is just my very biased personal opinion and I respect your opinion if you disagree! :)

Instead, it has a monetary policy of “minimum viable issuance”, not only is this is a good thing for network security, but with the addition of EIP-1559, it leaves the door open to the possibility of ETH issuance going negative. In short, EIP-1559 changes the fee market to make transaction prices more efficient (helping to alleviate high gas fees!) by burning a variable base fee which changes based on network usage demand rather than using a highest bidder market where miners simply include who pays them the most. This will result in most of the ETH being paid in transaction fees being burned. As of late, the amount which would be burned if EIP-1559 was in Ethereum right now would make ETH a deflationary asset!

Layer 2 Scaling

In the mean time while we are waiting for ETH 2.0, layer 2 scaling is here. Right now, projects such as Deversifi or Loopring utilise rollups to scale to thousands of tx/s on their decentralised exchange platforms or HoneySwap which uses xDai to offer a more scalable alternative to UniSwap. Speaking of which, big DeFi players like UniSwap and Synthetix are actively looking into using optimistic rollups to scale while maintaining composability between DeFi platforms. The most bullish thing about L2 scaling is all of the variety of options. Here’s a non exhaustive list of Ethereum L2 scaling solutions: - Aztec protocol (L2 scaling + privacy!) - ZKSync - Loopring - Raiden - Arbitrum Rollups - xDai - OMGNetwork - Matic - FuelLabs - Starkware - Optimism - Celer Network - + Many more

DeFi and Composability

If you’re reading this, I am sure you are aware of the phenomena which is Decentralised Finance (DeFi or more accurately, open finance). Ethereum is the first platform to offer permissionless and immutable financial services which when interacting with each other, lead to unprecedented composability and innovation in financial applications. A whole new world of possibilities are opening up thanks to this composability as it allows anyone to take existing pieces of open source code from other DeFi projects, put them together like lego pieces (hence the term money legos) and create something the world has never seen before. None of this was possible before Ethereum because typically financial services are heavily regulated and FinTech is usually proprietary software, so you don’t have any open source lego bricks to build off and you have to build everything you need from scratch. That is if what you want to do is even legal for a centralised institution!
Oh, and if you think that DeFi was just a fad and the bubble has popped, guess again! Total value locked in DeFi is currently at an all time high. Don’t believe me? Find out for yourself at: https://defipulse.com

NFTs and tokeniation

NFTs or “Non-Fungible Tokens” - despite the name which may confuse a layman - are a basic concept. They are unique tokens with their own unique attributes. This allows you to create digital art, human readable names for your ETH address (see ENS names and unstoppable domains), breedable virtual collectible creatures like crypto kitties, ownable in game assets like Gods Unchained cards or best of all in my opinion, tokenised ownership of real world assets which can even be split into pieces (this doesn’t necessarily require an NFT. Fungible tokens can be/are used for some of the following use cases). This could be tokenised ownership of real estate (see RealT), tokenised ownership of stocks, bonds and other financial assets (which by the way makes them tradable 24/7 and divisible unlike through the traditional system) or even tokenised ownership of the future income of a celebrity or athlete (see when NBA Star Spencer Dinwiddie Tokenized His Own NBA Contract.

Institutional Adoption

Ethereum is by far the most widely adopted blockchain by enterprises. Ethereum’s Enterprise Ethereum Alliance (EEA) is the largest blockchain-enterprise partnership program and Ethereum is by far the most frequently leveraged blockchain for proof of concepts and innovation in the blockchain space by enterprises. Meanwhile, there are protocols like the Baseline protocol which is a shared framework which allows enterprises to use Ethereum as a common frame of reference and a base settlement layer without having to give up privacy when settling on the public Ethereum mainnet. This framework makes adopting Ethereum much easier for other enterprises.

Institutional Investment

One of Bitcoin’s biggest things it has going for it right now is the growing institutional investment. In case you were wondering, Ethereum has this too! Grayscale offers investment in the cryptocurrency space for financial institutions and their Ethereum fund has already locked up more than 2% of the total supply of ETH. Not only this, but as businesses transact on Ethereum and better understand it, not only will they buy up ETH to pay for their transactions, but they will also realise that much like Bitcoin, Ethereum is a scarce asset. Better yet, a scarce asset which offers yield. As a result, I expect to see companies having ETH holdings become the norm just like how Bitcoin is becoming more widespread on companies’ balance sheets.

The state of global markets

With asset prices in almost every asset class at or near all-time highs and interest rates lower than ever and even negative in some cases, there really aren’t many good opportunities in the traditional financial system right now. Enter crypto - clearly the next evolution of financial services (as I explained in the section on DeFi earlier in this post), with scarce assets built in at the protocol layer, buying BTC or ETH is a lot like buying shares in TCP/IP in 1990 (that is if the underlying protocols of the internet could be invested in which they couldn’t). Best of all, major cryptos are down from their all-time highs anywhere between 35% for BTC or 70% for ETH and much more for many altcoins. This means that they can significantly appreciate in value before entering uncharted, speculative bubble territory.
While of course we could fall dramatically at any moment in the current macro financial conditions, as a longer term play, crypto is very alluring. The existing financial system has shown that it is in dire need of replacing and the potential replacement has started rearing its head in the form of crypto and DeFi.

Improvements in user onboarding and abstracting away complexity

Ethereum has started making huge leaps forward in terms of usability for the end user. We now have ENS names and unstoppable domains which allow you to send ETH to yournamehere.ETH or TrickyTroll.crypto (I don’t actually have that domain, that’s just an example). No longer do you have to check every character of your ugly hexadecimal 0x43AB96D… ETH address to ensure you’re sending your ETH to the right person. We also have smart contract wallets like Argent wallet or the Gnosis safe. These allow for users to access their wallets and interact with DeFi self-custodially from an app on their phone without having to record a private key or recovery phrase. Instead, they offer social recovery and their UI is straight forward enough for anyone who uses a smart phone to understand. Finally, for the more experienced users, DApps like Uniswap have pretty, super easy to use graphical user interfaces and can be used by anyone who knows how to run and use a browser extension like Metamask.

The lack of an obvious #1 ETH killer

One of Ethereum’s biggest threats is for it to be overthrown by a so-called “Ethereum killer” blockchain which claims to do everything Ethereum can do and sometimes more. While there are competitors which are each formidable to a certain extent such as Polkadot, Cardano and EOS, each have their own weaknesses. For example, Polkadot and Cardano are not fully operational yet and EOS is much more centralised than Ethereum. As a result, none of these competitors have any significant network effects just yet relative to the behemoth which is Ethereum. This doesn’t mean that these projects aren’t a threat. In fact, I am sure that projects like Polkadot (which is more focused on complimenting Ethereum than killing it) will take a slice out of Ethereum’s pie. However, I am still very confident that Ethereum will remain on top due to the lack of a clear number 2 smart contract platform. Since none of these ETH killers stands out as the second place smart contract platform, it makes it much harder for one project to create a network effect which even begins to threaten Ethereum’s dominance. This leads me onto my next reason - network effects.

Network effects

This is another topic which I made a previous post on. The network effect is why Bitcoin is still the number one cryptocurrency and by such a long way. Bitcoin is not the most technologically advanced cryptocurrency. However, it has the most widespread name recognition and the most adoption in most metrics (ETH beats in in some metrics these days). The network effect is also why most people use Zoom and Facebook messengeWhatsApp despite the existence of free, private, end to end encrypted alternatives which have all the same features (https://meet.jit.si/ for zoom alternative and Signal for the private messenger app. I highly recommend both. Let’s get their network effects going!). It is the same for Bitcoin. People don’t want to have to learn about or set up a wallet for alternative options. People like what is familiar and what other people use. Nobody wants to be “that guy” who makes you download yet another app and account you have to remember the password/private key for. In the same way, Enterprises don’t want to have to create a bridge between their existing systems and a dozen different blockchains. Developers don’t want to have to create DeFi money legos from scratch on a new chain if they can just plug in to existing services like Uniswap. Likewise, users don’t want to have to download another browser extension to use DApps on another chain if they already use Ethereum. I know personally I have refrained from investing in altcoins because I would have to install another app on my hardware wallet or remember another recovery phrase.
Overthrowing Ethereum’s network effect is one hell of a big task these days. Time is running out for the ETH killers.

Ethereum is the most decentralised and provably neutral smart contract platform

Ethereum is also arguably the most decentralised and provably neutral smart contract platform (except for maybe Ethereum Classic on the neutrality part). Unlike some smart contract platforms, you can’t round up everyone at the Ethereum Foundation or any select group of people and expect to be able to stop the network. Not only this, but the Ethereum foundation doesn’t have the ability to print more ETH or push through changes as they wish like some people would lead you on to believe. The community would reject detrimental EIPs and hard fork. Ever since the DAO hack, the Ethereum community has made it clear that it will not accept EIPs which attempt to roll back the chain even to recover hacked funds (see EIP-999).
Even if governments around the world wanted to censor the Ethereum blockchain, under ETH 2.0’s proof of stake, it would be incredibly costly and would require a double digit percentage of the total ETH supply, much of which would be slashed (meaning they would lose it) as punishment for running dishonest validator nodes. This means that unlike with proof of work where a 51% attacker can keep attacking the network, under proof of stake, an attacker can only perform the attack a couple of times before they lose all of their ETH. This makes attacks much less financially viable than it is on proof of work chains. Network security is much more than what I laid out above and I am far from an expert but the improved resistance to 51% attacks which PoS provides is significant.
Finally, with the US dollar looking like it will lose its reserve currency status and the existing wire transfer system being outdated, superpowers like China won’t want to use US systems and the US won’t want to use a Chinese system. Enter Ethereum, the provably neutral settlement layer where the USA and China don’t have to trust each other or each other’s banks because they can trust Ethereum. While it may sound like a long shot, it does make sense if Ethereum hits a multi-trillion dollar market cap that it is the most secure and neutral way to transfer value between these adversaries. Not to mention if much of the world’s commerce were to be settled in the same place - on Ethereum - then it would make sense for governments to settle on the same platform.

ETH distribution is decentralised

Thanks to over 5 years of proof of work - a system where miners have to sell newly minted ETH to pay for electricity costs - newly mined ETH has found its way into the hands of everyday people who buy ETH off miners selling on exchnages. As pointed out by u/AdamSC1 in his analysis of the top 10K ETH addresses (I highly recommend reading this if you haven’t already), the distribution of ETH is actually slightly more decentralised than Bitcoin with the top 10,000 ETH wallets holding 56.70% of ETH supply compared to the top 10,000 Bitcoin wallets which hold 57.44% of the Bitcoin supply. This decentralised distribution means that the introduction of staking won’t centralise ETH in the hands of a few wallets who could then control the network. This is an advantage for ETH which many proof of stake ETH killers will never have as they never used PoW to distribute funds widely throughout the community and these ETH killers often did funding rounds giving large numbers of tokens to VC investors.

The community

Finally, while I may be biased, I think that Ethereum has the friendliest community. Anecdotally, I find that the Ethereum developer community is full of forward thinking people who want to make the world a better place and build a better future, many of whom are altruistic and don’t always act in their best interests. Compare this to the much more conservative, “at least we’re safe while the world burns” attitude which many Bitcoiners have. I don’t want to generalise too much here as the Bitcoin community is great too and there are some wonderful people there. But the difference is clear if you compare the daily discussion of Bitcoin to the incredibly helpful and welcoming daily discussion of EthFinance who will happily answer your noob questions without calling you an idiot and telling you to do you own research (there are plenty more examples in any of the daily threads). Or the very helpful folks over at EthStaker who will go out of their way to help you set up an ETH 2.0 staking node on the testnets (Shoutout to u/superphiz who does a lot of work over in that sub!). Don’t believe me? Head over to those subs and see for yourself.
Please don’t hate on me if you disagree about which project has the best community, it is just my very biased personal opinion and I respect your opinion if you disagree! :)

TL;DR:

Too many people over at r/bitcoin would rather have new users lose funds than help them recover them, as long as it reinforces the "BCH is a scam" narrative.

https://np.reddit.com/Bitcoin/comments/ggwdy7/i_accidentally_sent_bch_to_my_btc_wallet_please/
Long story short: OP is a newcomer who bought BCH at bitcoin.com thinking they were buying BTC, and mistakenly sent it to a BTC address.
They asked for help on reddit, and they overwhelmingly got responses of the type "Sorry for your loss" and "You have been scammed", leading them to believe they lost their funds.
OP actually responded to a post which told them they lost their money, actually believing that was the case. Conceivably, based on these responses OP could have deleted the wallet, ACTUALLY losing the funds.
Some subreddit mods came as well, and impressively, they did NOT inform OP that the funds were recoverable, they directed OP to ask conman Roger for their money.
As is turns out, the address was not segwit, thus the funds were fully recoverable.
Thankfully, some redditors guided OP to recover the funds but makes me wonder how many other newcomers might not have OP's luck and actually lose their funds because of people over there misguiding them, since they either are ignorant, or pushing a narrative is more important to them than actually helping newcomers recover their money.
Edit: Aaand, here it is: I have just been banned from bitcoin for letting OP know how to recover their funds!
Given reason:
Note from the moderators:
brigading altcoin scammer
Also the moderator removed another reply comment that was thanking me for actually being helpful in guiding OP recover their funds.

Gridcoin 5.0.0.0-Mandatory "Fern" Release

https://github.com/gridcoin-community/Gridcoin-Research/releases/tag/5.0.0.0
Finally! After over ten months of development and testing, "Fern" has arrived! This is a whopper. 240 pull requests merged. Essentially a complete rewrite that was started with the scraper (the "neural net" rewrite) in "Denise" has now been completed. Practically the ENTIRE Gridcoin specific codebase resting on top of the vanilla Bitcoin/Peercoin/Blackcoin vanilla PoS code has been rewritten. This removes the team requirement at last (see below), although there are many other important improvements besides that.
Fern was a monumental undertaking. We had to encode all of the old rules active for the v10 block protocol in new code and ensure that the new code was 100% compatible. This had to be done in such a way as to clear out all of the old spaghetti and ring-fence it with tightly controlled class implementations. We then wrote an entirely new, simplified ruleset for research rewards and reengineered contracts (which includes beacon management, polls, and voting) using properly classed code. The fundamentals of Gridcoin with this release are now on a very sound and maintainable footing, and the developers believe the codebase as updated here will serve as the fundamental basis for Gridcoin's future roadmap.
We have been testing this for MONTHS on testnet in various stages. The v10 (legacy) compatibility code has been running on testnet continuously as it was developed to ensure compatibility with existing nodes. During the last few months, we have done two private testnet forks and then the full public testnet testing for v11 code (the new protocol which is what Fern implements). The developers have also been running non-staking "sentinel" nodes on mainnet with this code to verify that the consensus rules are problem-free for the legacy compatibility code on the broader mainnet. We believe this amount of testing is going to result in a smooth rollout.
Given the amount of changes in Fern, I am presenting TWO changelogs below. One is high level, which summarizes the most significant changes in the protocol. The second changelog is the detailed one in the usual format, and gives you an inkling of the size of this release.

Highlights

Protocol

Note that the protocol changes will not become active until we cross the hard-fork transition height to v11, which has been set at 2053000. Given current average block spacing, this should happen around October 4, about one month from now.
Note that to get all of the beacons in the network on the new protocol, we are requiring ALL beacons to be validated. A two week (14 day) grace period is provided by the code, starting at the time of the transition height, for people currently holding a beacon to validate the beacon and prevent it from expiring. That means that EVERY CRUNCHER must advertise and validate their beacon AFTER the v11 transition (around Oct 4th) and BEFORE October 18th (or more precisely, 14 days from the actual date of the v11 transition). If you do not advertise and validate your beacon by this time, your beacon will expire and you will stop earning research rewards until you advertise and validate a new beacon. This process has been made much easier by a brand new beacon "wizard" that helps manage beacon advertisements and renewals. Once a beacon has been validated and is a v11 protocol beacon, the normal 180 day expiration rules apply. Note, however, that the 180 day expiration on research rewards has been removed with the Fern update. This means that while your beacon might expire after 180 days, your earned research rewards will be retained and can be claimed by advertising a beacon with the same CPID and going through the validation process again. In other words, you do not lose any earned research rewards if you do not stake a block within 180 days and keep your beacon up-to-date.
The transition height is also when the team requirement will be relaxed for the network.

GUI

Besides the beacon wizard, there are a number of improvements to the GUI, including new UI transaction types (and icons) for staking the superblock, sidestake sends, beacon advertisement, voting, poll creation, and transactions with a message. The main screen has been revamped with a better summary section, and better status icons. Several changes under the hood have improved GUI performance. And finally, the diagnostics have been revamped.

Blockchain

The wallet sync speed has been DRASTICALLY improved. A decent machine with a good network connection should be able to sync the entire mainnet blockchain in less than 4 hours. A fast machine with a really fast network connection and a good SSD can do it in about 2.5 hours. One of our goals was to reduce or eliminate the reliance on snapshots for mainnet, and I think we have accomplished that goal with the new sync speed. We have also streamlined the in-memory structures for the blockchain which shaves some memory use.
There are so many goodies here it is hard to summarize them all.
I would like to thank all of the contributors to this release, but especially thank @cyrossignol, whose incredible contributions formed the backbone of this release. I would also like to pay special thanks to @barton2526, @caraka, and @Quezacoatl1, who tirelessly helped during the testing and polishing phase on testnet with testing and repeated builds for all architectures.
The developers are proud to present this release to the community and we believe this represents the starting point for a true renaissance for Gridcoin!

Summary Changelog

Accrual

Changed

Most significantly, nodes calculate research rewards directly from the magnitudes in EACH superblock between stakes instead of using a two- or three- point average based on a CPID's current magnitude and the magnitude for the CPID when it last staked. For those long-timers in the community, this has been referred to as "Superblock Windows," and was first done in proof-of-concept form by @denravonska.

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).

[ 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.)

Just found an old .dat file with 25 BTC in it! Is there a "light" wallet that this works with or just the node?

I kind of want to get the private key out of here today. Thanks!
Update: This turned out to only have .9 BTC which means the 25 dat file is in another account. This wallet we found was the pizza funds wallet apparently. IN 2012 it was something like $3 so still a substantial find. Thank you everyone for your help and advice.

The Kirobo Startup has developed technology to return erroneously sent BTC

The Kirobo Startup has developed technology to return erroneously sent BTC

The Kirobo Startup has developed technology to return erroneously sent BTC

Israeli startup Kirobo has developed a technology that allows you to return bitcoins mistakenly sent to the wrong addresses.

The Retrievable Transfer function developed by Kirobo works by creating a new level on the existing blockchain protocol. When using it, users have the opportunity to “roll back” a transaction sent to the wrong wallet address, as the company says in a press release. This method is currently only available using Ledger wallets.

“OUR GOAL IS TO MAKE BLOCKCHAIN TRANSACTIONS AS SIMPLE AND SECURE AS ONLINE BANKING,” SAID KIROBO CEO ASAF NAIM.

According to the company, the transaction recipient must enter a unique transaction code to receive coins. Until the recipient enters the correct code, the sender can return them at any time.
The sender can lose coins (and often actually loses) when he sends them to an incorrectly entered address. Kirobo cites as an example the result of a survey that showed that 18% of respondents lost crypto assets due to such errors. According to the company, if making transactions less risky, it will attract new users to the cryptocurrency industry.
The company claims that it does not store user private keys, and the unique code simply determines whether the transaction will be completed. This feature can work offline if Kirobo servers are unavailable.
The Kirobo platform has received support from the Israel Innovation Authority, the government unit responsible for promoting research and development. According to a press release, the company also passed an audit of the cybersecurity company Scorpiones Group.
Kirobo’s Retrievable Transfer feature is available for transferring BTC to Ledger wallets. Kirobo claims that it will work in other wallets in the coming months.
The problem of returning cryptocurrencies sent by mistake has existed in the industry since its inception. In February, it was reported that an unknown miner was able to recover almost 9,000 BCH, erroneously sent by users to SegWit addresses, and assigned these coins. In addition, in May of this year, the Ethereum community discussed the possibility of creating a decentralized autonomous organization (DAO) to return ETH sent to incorrect addresses.

Building Ergo: Storage rent

We’ve designed Ergo with long-term economic sustainability in mind, and storage rent is one of the ways we’re ensuring miners stay profitable well into the future. One community member, Robert, describes this function as ‘on-chain garbage collection’ that reduces the problem of blockchain bloat – and even makes it profitable.
The 2020 block reward reduction will probably be the most important halving Bitcoin ever experiences. This is the point where the narrative of programmatic scarcity and digital gold will truly be proven, in the context of the sharpest economic downturn in living memory. In previous halvings, Bitcoin has still been in its infancy, a niche experiment. Future halvings will confirm the principle. But this one is the watershed.
Looking ahead, though, what happens in 20 or 30 years, when block rewards have fallen so far that miners have to rely on tx fees and potentially other sources of revenue? Will Bitcoin be sustainable? What will be the impact on the ecosystem?
The simple answer is that we don’t know.
Mining rewards are a key feature in maintaining the security of proof-of-work blockchains like Bitcoin and Ergo. And so, while we have deliberately kept many of Bitcoin’s tried and tested features, we have updated this one to give miners a boost when block rewards have fallen to zero.
Lost coins
Digital scarcity is an important feature of Ergo. Like Bitcoin, ERG are designed to be a finite resource and long-term store of value. We do not agree with the principle of infinite inflation.
And yet, this has to be balanced against the needs to pay miners to secure the blockchain and process transactions. Without adequate compensation for miners, there is no viable blockchain at all. Ergo approaches this by slowly recycling lost coins, in a feature we call ‘Storage rent’.
Studies suggest that as many as 4 million BTC may have been lost forever. These are coins that were mined in the early days of Bitcoin and stored on hard drives that were subsequently thrown away or destroyed because the owners forgot about them or thought they were worthless, as well as coins in addresses for which the private keys have been lost. (And, of course, there’s Satoshi’s estimated holdings of 1 million BTC, which may never move.)
Where coins have genuinely been permanently taken out of circulation in this way, it makes sense to have a mechanism to recover them and put them back into the blockchain economy. That way, we can preserve digital scarcity without unnecessarily accelerating it. In other words, by attempting to stick to the intended algorithmic supply for any given point in time.
Ergo’s halving schedule is faster than Bitcoin’s. Block rewards start at 75 ERG, and decrease steadily after the first two years. There is no ‘long tail’ of emission, and after eight years block rewards will fall to zero. After that, total supply will be fixed. The number of ERG in existence will never be more than 97,739,925.
Storage fees
From that point, however, miners will need further incentives to secure the network. Miners have ongoing costs in terms of bandwidth and storage, and in cases where coins are simply left for years, there is typically no charge for reflecting the value of securing them. The tx fee that is paid up-front in Bitcoin is the only charge ever made for storing those coins.
In Ergo, in addition to transaction fees, miners will also be able to collect storage rent fees on UTXOs that have not been moved for four years or more.
Fees will be deducted slowly, over time – the unmoved UTXOs will not simply be appropriated by miners. Anyone who wants to avoid this simply needs to move their balances once every four years, which is not an onerous requirement for helping incentivise miners and avoiding the deflationary consequences of lost coins. You can read more about how fees will be levied in this paper.
In this way, Ergo seeks to ensure a balance between maintaining digital scarcity, on the one hand, and giving miners long-term incentives to secure the blockchain, on the other – long past the point where new coins have ceased to be released.
