Trust Fabric
The substrate that links identity, policy, evidence and the trust index into one consistent, on-chain view.
What it does
The Trust Fabric is the connective substrate of the platform. It links identity (DIDs), the deterministic policy-core, Hedera-anchored signed evidence and the HCS-28 Trust Index into one consistent view, so every service shares the same answer to who is acting, what they are permitted to do, and how far they can be trusted — all re-derivable on-chain by anyone.
Inside Trust Fabric
The core functions this engine provides across the Trust Fabric.
Trust Fabric composes with the Trust Fabric
Every engine is independently useful and interoperates through one API-first Trust Fabric — so identity, evidence, policy, risk and certification stay consistent across your AI estate.
Related engines
Identity Engine
Issues each agent a verifiable, self-certifying DID and proves control of its key — the root every other engine trusts.
- did:hedera / did:key
- Key proof (verify-key / BYOK)
- Public DID resolver
- HCS registry anchoring
Ownership & Delegation
Binds an agent to its owner and to a VC-issued mandate — with instant revocation.
- Verified principal (KYC/KYB), or a disclosed free-tier allowance
- VC-issued mandate (scope, caps, merchants)
- Resource scope — which systems and data
- Sub-delegation that can only narrow
- Delegated issuance
Agent Passport
A signed, portable snapshot of an agent's identity, ownership, declared purpose and current capabilities — composed from data the platform already tracks.
- Signed identity + capability snapshot
- Composed from existing identity/version/assurance data
- Independently revocable from containment
- Reissued as the agent's profile changes
