The Trust Body of Knowledge
A shared, structured reference of the concepts, standards, patterns and terminology behind the framework — grounded in a real, published protocol.
01
Concepts
Precise definitions and models for identity, delegated authority, deterministic policy, evidence, risk, certification and trust — the vocabulary the protocol implements, not abstract theory.
02
The standards it builds on
- W3C DIDs (did:hedera, did:key) & Verifiable Credentials
- ODRL agent-mandate policy profile
- Hedera Consensus Service (HCS-1/2/10/11/14) — identity, registry, messaging
- HCS-28 — the Agent Transparency / trust-attribution shape
- x402 — payment bound to an authorization
- Ed25519 signatures, Merkle inclusion proofs, BBS selective disclosure
03
Patterns
- Bring-your-own-key & self-certifying did:key
- Cooperative vs trustless enforcement
- Human-in-the-loop escalation & approval
- Two-phase authorize → capture with settlement proof
- Delegated issuance without credential sharing
04
Reference
- Reason-code catalog & the machine-readable policy schema
- The atom catalog (the policy 'context contract')
- Reference architectures & control mappings
- Offline verifiers (evidence, policy bundle, trust record)
