Protocol Overview | AT Protocol
Identity | AT Protocol In the AT protocol, each user has a domain name handle such as alice.host.com or alice.com and a consistent “DID” (distributed ID) that allows migration between hosts.
- Identity management: users create stable global IDs and securely distribute public keys; IDs are portable and keys can be rotated.
- Identifiers: Two types of identifiers are used: handles and DIDs. Handles serve as DNS names, and DIDs serve as secure and stable identifiers.
- Handle resolution: The atproto handle resolves to a DID that resolves to a DID document containing the user’s signing public key and hosting service.
- Hosting Provider
