Thanks for contributing this history. I didn’t realize fiatjaf was so liberal with his cryptocurrency endeavors :) I agree Jack brought a lot of social consensus to galvanize early visibility (and contributed a lot of funding over time)! I’ve heard the Taproot/identity point mentioned before, but I don’t know much about the relationship. Can you tell more about this? Are npubs/nsec specs inherited from something in Taproot?

Yes, they are exactly the same idenity except nostr starts "npub" and taproot starts "bc". Both use schnorr sigs. So that means that all nostr accounts are all wallets, and all taproot accounts can participate in nostr social and apps. Nostr has a distributed ledger with best in class consensus via taproot. Any nostr user can send money to any other nostr user, they just dont do it, or are not aware. On top of that all of the layer 2 solutions that emerge on bitcoin, rgb, taproot assets, runes, omni, colored coins, liquid, smart contracts, can be used with nostr, and vice versa. Again this is not used at the moment, but it unlocks a huge amount of functionality. Whether or not the current community wants that functionality, I dont know. But there is enormous untapped potential.
Concrete example: Your npub: npub1kuy0wwf0tzzqvgfv8zpw0vaupkds3430jhapwrgfjyn7ecnhpe0qj9kdj8 Your testnet address: tb1pkuy0wwf0tzzqvgfv8zpw0vaupkds3430jhapwrgfjyn7ecnhpe0qxdufq2 Notice they are almost identical characters. So I just sent you 1 million testnet sats here: I just used a directive in my subkey (see below) to send you the sats. So much is possible!
