> most cryptocurrencies haven't adopted PoS despite it facially seeming better/"less wasteful" Most post-launch cryptocurrencies were designed a long time ago, though. If you look at recent credible projects, most involve proof of stake: NEAR, Solana, Coda (Mina), Cosmos, Celo, Polkadot, etc. I can only think of a couple recent blockchain designs based on proof of work: Grin and Iron Fish.
