Nostr relay operators and Cashu mint operators are independent. If a relay accepts ecash issued by a mint, users can obtain ecash from the mint and use it as postage on their messages. Once the Nostr relay receives it, it can be exchanged for LN sats.… Keychat May 30, 2024, 6:19 AM
When we started conceptualizing Keychat, we aimed to design a chat application that surpasses Signal. Our design process was divided into four steps.
