Then it appears the complaint that NFTs using too much electricity that you see on Twitter a lot is about Ethereum doing proof of work, which it won't much longer as it transitions to proof of stake. I'm really interested in Chia, which is proof of space. I wouldn't give it much consideration except it's by Bram Cohen who did BitTorrent.
