ATProtocol Attestations: Cryptographic Signatures for the Decentralized Web - Nick's Blog
This post introduces the formal ATProtocol attestation specification, a framework for adding cryptographic signatures to ATProto records through two complementary patterns: inline attestations that embed signatures directly in records, and remote attestations that store proof in separate repository records. The specification prevents replay attacks through repository binding, uses CID-based content addressing for integrity, and provides the cryptographic foundation for verified credentials, trusted content, and authenticated interactions in the decentralized ATProtocol ecosystem.

π¨ Docs News!! you all asked for it, so I did a medium-sized refactor of the Auth section of the atproto docs: atproto.com/guides/auth I appreciated all the little pushes here as well as contributions from @danabra.mov and @zzstoatzz.io β much happier with the flow here now and hope you will be too!
