annotated-spec

Even a relatively light reading of the Annotated Specs for Eth2[1] and/or the Eth Org's Proof of Stake FAQs[2] suggests the designers (and independent implementer-teams who gave feedback to designers, who gave direction to the implementers... lather, rinse, repeat) understand it's important to consider the overall system "outside of the comfort zone". [1] one such: https://github.com/ethereum/annotated-spec/blob/master/phase... [2] https://eth.wiki/en/concepts/proof-of-stake-faqs

https://github.com/ethereum/annotated-spec/blob/master/phase... After withdrawal is completed, your node would no longer be in the set of active validators and from that time could not validly propose a block or submit an attestation (or, more accurately, be selected as a block proposer, etc.)

I agree about the energy use of PoW. On Ethereum, the PoS beacon chain has been live for almost a year now [1], with the merging of the PoW and PoS networks happening next year. We're now at the point where the specs for the merge transition are ready [2], clients are already being modified to target the release-spec [3], and the first long-lived testnet will go live by December. I'd personally expect the Merge to happen by May. [1] https://beaconcha.in [2] https://github.com/ethereum/annotated-spec/blob/master/merge...
