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.

Atproto Is the Context Window You Own - The Tropopause
pckt.blogOh this is interesting. At first I thought it was yet another lexicon to wrap data on, but it's a way for anyone to use ATProto as a discovery mechanism for their non-PDS-hosted datasets. I hadn't thought of the ATmosphere and the relays as a way to surface arbitrary existing data until know.

🪩 Introducing matadisco.org! — a way to discover open datasets via #atproto that doesn't depend on any single institution staying online. 🕺🏼 We have more public data than ever (satellite imagery, climate models, genomic sequences), but finding it is still painfully hard.
