How does Nostr work? (source:https://github.com/nostr-protocol/nostr#how-does-nostr-work https://github.com/nostr-protocol/nostr#how-does-nostr-work) * There are two components: clients and relays. Each user runs a client. Anyone can run a relay. * Every user is identified by a public key. Every post is signed. Every client validates these signatures. * Clients fetch data from relays of their choice and publish data to other relays of their choice. A relay doesn't talk to another relay, only directly to users. * For example, to "follow" someone a user just instructs their client to query the relays it knows for posts from that public key. * On startup, a client queries data from all relays it knows for all users it follows (for example, all updates from the last day), then displays that data to the user chronologically. * A "post" can contain any kind of structured data, but the most used ones are going to find their way into the standard so all clients and relays can handle them seamlessly.
