Breadcrumbs: physical attestations for ecosystem contributions

Hey atmospheric friends, over the weekend I started experimenting with physical attestations, as part of my exploration of an ATScience community labeller. breadcrumbs: physical objects — NFC tags, printed QR codes — that let someone attest to their own participation in something, or let an authority attest that someone did something specific. Two record types separate self-attested contributions (crumbs) from community-authored ones (badges). Lexicons: - `id.breadcrumbs.trail` — self-minted...

A New Form of Verification on Bluesky - Bluesky

We’re introducing a new layer of verification — a user-friendly, easily recognizable badge. Additionally, independent organizations can verify accounts directly through our Trusted Verifiers feature.

test: appraisal is a required field with no conformance module · Issue #63 · agentrust-io/trace-tests

appraisal is in the schema's top-level required list, but none of the seven conformance modules checks it. The only coverage today is the JSON Schema enum (exercised in the pytest suite) and a ...

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.

GPG signature verification

When you’re building software with people from around the world, sometimes it’s important to validate that commits and tags are coming from an identified source. Git supports signing commits and…

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.

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.
