What is the NOSTR protocol?
NOSTR, or Notes and Other Stuff Transmitted by Relays, is a simple decentralized network protocol based on cryptographic keypairs. It is being touted as tamperproof, resilient, simple, and effective. While it is decantralized, it is not peer to peer; communication is facilitated through relay servers that can be hosted by anyone. Since the signature verification process is performed client-side and through multiple relay servers, a malicious user can not harm the network by altering their relay server. A possible use case is to use NOSTR to create a censorship-resistant social network.
