What’s with the Nostr/Bitcoin overlap? I’m not a big fan of cryptocurrency or blockchain-all-the-things. And Nostr itself (thankfully) isn’t implemented atop a blockchain.
The creator of nostr @fiatjaf has also done work in the bitcoin community. Lots of bitcoiners are the open source contributors to these clients and have even took implementing features like “zaps” which are micropayments denominated in sats (smallest bits of bitcoins) paid over the lightning network (instant and feeless) You can zap someone as small as 1 sat (fraction of a cent) if you like.
