Nostr is a decentralized social protocol and censorship-resistant messaging standard. It operates as a distributed event relay network where user identities are defined by public-key cryptography rather than centralized account databases.
The protocol enables the exchange of cryptographically signed messages across a network of independent relays. This system allows for the broadcasting of signed notes to multiple servers to ensure content availability and permanence, while using public-key pairs to prove authorship and authenticity without a central registry.
The system covers distributed content delivery and identity verification. It supports the publication of signed notes and the retrieval of user content from remote servers to reconstruct chronological activity feeds. Security is maintained through client-side verification of message authenticity and integrity.
