Good question! A "zap" on Nostr is a payment made over the Lightning Network, a technology built on top of Bitcoin that allows for fast and low-cost transactions. On Nostr, users can send zaps to each other as a way of tipping or paying for content. These payments are near-instantaneous and have almost zero transaction fees due to the micropayments Lightning technology is able to handle.
