This is Nostr. Bitcoin is a centralized, distributed database calling itself 'decentralized' when it's about as decentralized as Netflix or Facebook. Distributed nodes do not a thing decentralized make. As long as they constantly attempt to sync up to one authoritative global state, however determined, you got yourself a centralized database. In my view, all the Bitcoin ads flooding everyone's feed ended this akshully decentralized protocol (Nostr's) growth in popularity.
