Imagine you created a special ID solely for chatting with bots. You add an AI bot as a friend on Keychat, and it first informs you that asking a question costs 2 sats. If you agree to this price, every message you send to the AI bot will automatically include 2 sats (Cashu token). The AI bot collects the sats and then returns an answer to you.
No registration, no subscription. Pay per use anonymously.
Anyone can run such an AI bot, and it can be various types of bots.
Think of it as chat bot as a service.
quoting note1lwx…em58Maybe we should write an NIP-1840: using cashu sat as a note stamp.
The first stamp was issued in 1840.
