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.

Building Unforgeable Professional Endorsements with ATProtocol - Nick's Blog
Traditional professional endorsements on platforms like LinkedIn lack cryptographic proof—anyone could forge them, and the platform controls the truth. This article introduces a two-record architecture using ATProtocol's Content Identifiers (CIDs) and Decentralized Identifiers (DIDs) to create mathematically unforgeable mutual attestations. By separating proof creation from endorsement acceptance and leveraging the firehose for distributed validation, we build a system where both parties cryptographically consent and no central authority can manipulate the record.
Introducing attested.network: Proof of Payment for ATProtocol - Nick's Blog
attested.network is an open spec for decentralized proof of payments on ATProtocol, built on what we learned making atprotofans.com. It formalizes the three-party attestation model and opens it up for any app to implement.

LinkedClaims: publish and verify decentralized claims about any URI-addressable subject on the AT Protocol. Open standard by DIF Labs.
badge.blue — CID-First Attestation Specification
Specification for CID-first attestations on AT Protocol records. Inline and remote cryptographic signatures with replay-attack prevention.
Payments on Protocol - Nick's Blog
atprotofans.com was a proof of concept for payments on ATProtocol built at Graze Social. This post is about what we built, why proof of payment on protocol matters, and what it makes possible.
