The Nostr protocol is bold; it bravely uses public/private keys as the user's ID. Previously, too many people said that users were too foolish to safeguard their private keys. We should also boldly imagine that users might accept attaching a Bitcoin ecash stamp to each note.
i’m intrigued by the pay as you go model instead of subscriptions to monetize relays. have you done more writing about this idea? seems generally applicable throughout the ecosystem. i think of it like a zap for the relay? should reach relay get a bit of ecash? how might stamp pricing work or form a market across relays? how long would storage commitments be?
The reason we dislike the subscription model is that it requires a fixed public key. A fixed public key can compromise the privacy of metadata in encrypted messages. Stamp pricing would be generated through competition among relays. Different prices could correspond to different storage durations.
