Interesting. How does it work?
Hey, I just sent you a tip of 20 Nostracoin.
Nostracoin can be used to record your nostr events in the blockchain.
You might want to do that because
1. It is censorship resistant
2. Timestamps your note
3. Never drops your note
You can check your balance or view Nostr at https://nostraco.in

So, if you're posting on nostraco.in and you have credits, your event will be recorded in the Nostracoin blockchain.
