Sending payments of Bitcoin over the lightning network on Nostr.
On Nostr (decentralized social media), you can send zaps instead of likes on people's posts. The creator keeps 100% of the money sent.
Zaps can be worth fractions of a penny to thousands of dollars. Zaps are often measured in "sats". There are 100,000,000 sats in one bitcoin.
It's also like Venmo or Cashapp for bitcoiners. Instead of "just venmo me back" a person using bitcoin may say, "just zap me back". People can find their friends on the Nostr network and pay them without permission.
"I'd zap that"
"I'll pay for coffee, just zap me back"
"Sorry babe, I'm zapping another girl right now"
"Zap so many sats your grandchildren will think you're retarded"
"See how many zaps that post got"
"I'm a zap addict"
