Because it's hard. Also technical debt moving from Eth 1 to 2 makes it harder. My guess is another blockchain will execute PoS better because it won't have tec

  The original plan would have been hobbled by technical debt. They were going to implement the core algorithm as a smart contract on the old chain. It would have supported a much smaller number of stakers and shards. In mid-2018 they threw out that plan, choosing instead to implement PoS as an entirely separate chain, integrated with sharding. This entailed a delay of over a year, but it meant a minimum stake of 32 ETH instead of 1500, and an overall much more efficient and scalable system. There are three main phases, the first being the core proof-of-stake "beacon chain," which is currently running a multi-client testnet. There have been various proposals for migrating legacy Ethereum into all this; here's the latest: https://ethresear.ch/t/alternative-proposal-for-early-eth1-eth2-merge/6666 https://ethresear.ch/t/alternative-proposal-for-early-eth1-e...

  Cardano is PoS and released its testnet last month. Tezos is another.

    Cosmos is PoS and released its mainnet in March.

      A Proof of Stake consensus for a public blockchain like Ethereum has different requirements and is substantially harder to execute than for a permissioned network.

        Definitely agree, although it’s important to clarify that Cosmos is not permissioned. Anyone can start a validator and join the validating set.

  Only a Proof-of-Work system can migrate to Proof-of-Stake. In order for Proof-of-Stake to work right from the beginning it needs to have the network effect of many participants trusting the network
