#Nostr it's now live on #Nymchat ...enhanced NIP-17 group chats.
In Nymchat, group chats are end-to-end encrypted using NIP-44 + NIP-17 gift wraps. Now on Nymchat, when you create a group, it uses rotating ephemeral recipient keys for enhanced privacy.
This means each member generates a fresh ephemeral keypair when they send a message, and the new pubkey is advertised inside the encrypted rumor. Future messages to that member use their ephemeral key instead of their real pubkey, reducing the attack surface for honeypot relay correlation of group membership through timing attack.
