原来 Damus 是这样实现twitter功能的。。。
nostr-protocol/nostr: a truly censorship-resistant alternative to Twitter that has a chance of working
https://github.com/nostr-protocol/nostr
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.
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.
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.
