From my learning nostr is similar to Mastodon in that nodes can be spun up to host the platform, I’m definitely looking into wallets now!
There’s no blockchain here. Nostr supports payments over Lightning (layer 2 bitcoin). Why don’t you set up a wallet and see how it works?
Some options for you:
nostr:npub1hcwcj72tlyk7thtyc8nq763vwrq5p2avnyeyrrlwxrzuvdl7j3usj4h9rq
nostr:npub1getal6ykt05fsz5nqu4uld09nfj3y3qxmv8crys4aeut53unfvlqr80nfm
nostr:npub1ex7mdykw786qxvmtuls208uyxmn0hse95rfwsarvfde5yg6wy7jq6qvyt9

Yeah, it’s a bit different in that there are no instances. Nostr is a protocol that any client can connect to and you choose your own relays. In theory you could just have a relay for yourself and those you invite that no one else can publish to, but that’s not how it’s generally used.
