The first function of stamps is anti-spam. Messaging apps like Signal or WhatsApp require registration, and the sender’s address for messages is the user’s ID. Therefore, the server administrators of these apps can block IDs to prevent spam.

In the registration model, users do not have control over their own IDs.

Keychat users, on the other hand, do not need to register, as their locally generated npub serves as their ID. Furthermore, each message is sent from a constantly generated, unique address, rather than using the ID as the sending address. As a result, Keychat cannot block spam by blocking IDs.

The second function of stamps is to provide nostr relays with a sustainable source of revenue. Signal has been running at a loss, as discussed in this blog post: https://signal.org/blog/signal-is-expensive/

Keychat’s use of ecash sats as message stamps is primarily inspired by the postal system. Moreover, using ecash sats as stamps does not affect the metadata privacy of messages.
