Forgive my inexperience with crypto, but wouldn’t a solid implementation of Proof of Stake, as Ethereum is attempting, solve a lot of these energy demand issues, and therefore government angst and regulatory shutdowns? TFA didn’t mention PoS, and I have gotten the impression that the crypto community regards it the way people talk about fusion energy, “the future if someone ever figures it out.” HN is more knowledgeable about crypto than the average bear, so I’m wondering if this crowd expects the crypto bans to cool off once PoS is (ever) proven with a mainstream stablecoin, or if I’m missing any crucial details.
