Ask HN: How bad is proof-of-work blockchain energy consumption?
2 by furrowedbrow | 2 comments on Hacker News.
I'm not a blockchain/crypto expert by any means, but I've been hearing about how much energy the proof-of-work blockchains (Bitcoin, Ethereum, NFTs) consume. Unless I'm mistaken their whole design relies on cranking through more and more CPU cycles. Should we be more concerned about this? Are the concerns overblown? Are there ways to improve it without certain crypto currencies imploding?
