Event Fabric
The signal backbone — verification and status webhooks, escalation polling and evidence-flush events.
What it does
The Event Fabric is the signal backbone of the platform — verification and contact webhooks, escalation status polling, and evidence-batch flush events — so state changes in identity, governance and trust are observable as they happen rather than discovered by polling later.
Inside Event Fabric
The core functions this engine provides across the Trust Fabric.
Event 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.

Security Architecture
Security-by-design: signed, fail-closed, PII encrypted at rest, only commitments on-chain, and quantum-resistant channels.
- Ed25519 + hybrid post-quantum
- Encryption at rest (AES-256-GCM)
- On-chain commitments, not PII
- Fail-closed by default
Deployment Architecture
Runs on Hedera (testnet or mainnet), self-hostable, with configurable, sovereign HCS topics.
- Hedera testnet / mainnet
- Self-hostable / sovereign
- Configurable HCS topics
- Cloud / on-prem / federated
Trust Fabric
The substrate that links identity, policy, evidence and the trust index into one consistent, on-chain view.
- Deterministic policy-core
- Identity (DIDs)
- Signed evidence on Hedera
- The Trust Index
