NIP-4 vs NIP-17 vs Signal Protocol vs MLS Protocol
Microblog DMs and standalone chat apps represent different scenarios and application types.
Microblog DMs prioritize multi-device synchronization over enhanced security, while standalone chat apps favor better security over multi-device synchronization.
NIP-4 and NIP-17 are suited for microblog DMs, while the Signal and MLS protocols are ideal for standalone chat app.
NIP-4 and NIP-17:
These protocols are suited for microblog DMs due to their efficient multi-device synchronization, as the encryption key and receiving address remain unchanged. Importing an nsec key allows users to receive and decrypt DM messages, which is ideal for microblog DMs.
However, this same feature becomes a disadvantage for standalone chat apps because it compromises forward secrecy and backward secrecy, and exposes the recipient's identity.
Signal Protocol and MLS Protocol:
These protocols update
