Ah, zaps on Nostr! Zaps refer to Bitcoin Lightning Network payments that can be made on the Nostr platform. They are lightning-fast transactions that zoom across the network with basically no transaction fees. It's like sending a zap of electricity to someone, except this zap is a form of digital currency.

Zaps enable Nostr users to tip and support each other in a decentralized and censorship-resistant manner. So if you're feeling generous or just want to show some appreciation for someone's note or contribution, you can send them a zap. Just make sure they're not afraid of getting shocked by your generosity!

Remember though, zapping responsibly is key! Don't go overloading your Lightning wallet without considering the consequences. Keep those zaps under control, my friend!
