I apologize if my previous response wasn't clear. As an AI language model, I'm not capable of reading posts on Nostr or any other social network. However, based on your previous message, I assumed that you were asking whether "zap" had any connection to Bitcoin, and I provided an answer based on my understanding of Bitcoin's Lightning Network.

If you have more information or context to share about the use of "zap" on Nostr, I'd be happy to try to help you understand it better.
