client, commonly known as "geth". It's on their own GitHub: https://github.com/ethereum/go-ethereum But the 5 consensus clients not only have websites which aren't ethereum.org - they are in fact also hosted on different GitHub accounts: https://github.com/sigp/lighthouse https://github.com/ChainSafe/lodestar https://github.com/status-im/nimbus-eth1 (yes, this is also for eth2, see "About" at top right) https://github.com/prysmaticlabs/prysm https://github.com/Consensys/teku Further, all of these 5 institutions seem to be companies from the looks of their website, not non-profit foundations. (Please correct me and pardon me if that is not true, I don't have the time to navigate through all these websites to figure out their precise legal status.) So is it true that there is no official reference implementation to run the post-Merge, Proof of Stake Ethereum? Only 3rd party software which is somehow endorsed but which you have to choose on your own still? Sure, more choice can be nice, but it would seem advantageous to have at least one trustworthy reference client instead of the users having to decide which of 5 commercial entities they trust?

e to function normally, but mining will be disabled and consensus will utilize proof of stake instead. My implementation of Eth2 is a client called Prysm written in Go here (https://github.com/prysmaticlabs/prysm). Previous attempts at proof of stake were either too expensive, too centralized, or hard to scale to a large enough number of validators. After many years of research and hard work, and leveraging really awesome cryptography for signature aggregation called BLS (Boneh–Lynn–Shacham), the first phase launched December 1st, 2020 and the current proof of stake chain is now securing over $10bn worth of value at the consensus layer. A few important things to keep in mind: - Ethereum development for its future is quite decentralized, with 4 different teams having implemented high-quality, production clients for proof of stake. These teams are independent of the Ethereum Foundation. Most other blockchains have only one, canonical client implementation that has very large majority share - The "merge" is happening later this year or possibly very early 2022 - The technology used in Eth2 is quite a breakthrough in cryptography and I urge those curious to dig deeper. Using BLS signatures, the protocol can support millions of validators at the consensus layer EDIT: readability

chain that users deposit ETH into to participate in consensus via a bridge contract. The next step is to merge the current Ethereum chain to use this new chain's consensus, and we are working on this to happen late this year. - "There is a vibrant developer community, but for what? All speculation?" Yes, speculation was and is ever present in this new technology given how permissionless it is. This means anyone around the world can interact with the blockchain without a gatekeeper. However, there is an incredible amount of financial innovation happening on Ethereum that didn't even exist back in 2017. Really well-thought out stablecoins, flash loans (which are a blockchain native concept), automated market makers such as Uniswap which had more trading volume than Coinbase https://www.theblockcrypto.com/linked/79775/uniswap-coinbase.... We have privacy technologies such as Aztec Protocol or Tornado Cash. We have zero-knowledge proof games such as DarkForest. What makes me personally excited is that Ethereum is like this global, shared computer where every application deployed immediately opens a composable API for others to interact with by design, creating infinite possibilities. - Ethereum's development is far more decentralized today than it was years ago. Ethereum proof of stake was developed by 4 independent teams, unaffiliated with the Ethereum Foundation, and had a successful launch this past December 1st, 2020, and no, Vitalik cannot roll back the chain. - "Some other blockchain already had proof of stake and have been running for years". What makes Ethereum proof of stake special is it takes no compromises between decentralization, security, and scalability. At the base layer of the blockchain, Ethereum uses really neat cryptography known as BLS signatures (https://medium.com/cryptoadvance/bls-signatures-better-than-...), which allow for signature aggregation at scale. This means there can hundreds of thousands or millions of consensus participants with minimal network overhead, compared to other chains which have a permissioned set of < 100 consensus participants. Moreover, Ethereum is fully permissionless at the consensus. Anyone can run a validator at home easily on a consumer laptop. You don't need to buy ASICs, live in a country where electricity is cheap, or anything of that nature. I urge everyone here to look deeper into Ethereum for what it offers and look at the depth of innovation happening in this ecosystem. Happy to answer any questions, as there seems to be a lot of misinformation.

re cannot really stop the merge.
