I am one of the implementers of Ethereum Proof of Stake (https://github.com/prysmaticlabs/prysm) and I would like to clarify a lot of misconceptions around Ethereum and why we find this technology so exciting:

- Proof of stake has serious flaws if done from scratch, as you are trying to secure a network using value created out of thin air. Ethereum is migrating to proof of stake from proof of work, and has already built up a security pool of over $200bn USD market cap and a significant amount of activity. ETH as the native asset required for proof of stake has enough security pool to allow the migration to make sense.

- "You have been talking about proof of stake for years, wake me up when it happens". We launched proof of stake on December 1st, 2020 https://www.coindesk.com/valid-points-ether-staked-eth-2-0-q.... This runs as a parallel 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.
