Four protocols, one stack, total sovereignty:

|:---:|----------|--------------|
| S | Solid | Personal data pod — files, profiles, apps |
| A | ActivityPub | Federated social — Mastodon, Threads, WordPress |
| N | Nostr | Censorship-resistant social — relays, zaps, keys |
| D | DID | Decentralized identity — one key, every protocol |
