EXOCHAIN is chain-of-custody for autonomous execution.

Credential autonomous intent, verify delegated authority, and preserve evidentiary custody for agents, holons, humans, and AI-native systems.

Human → AVC → Agent → EXOCHAIN → Trust Receipt. Revocation cascades back through the credential graph.

The frame

Blockchain is the mechanism. Chain-of-custody is the purpose.

EXOCHAIN preserves every property you expect from a serious distributed ledger — deterministic ordering, cryptographic signatures, quorum, finality — and reframes the chain as a chain-of-custody for autonomous action.

MECHANISM

  • Blockchain
  • deterministic ordering
  • cryptographic signatures
  • quorum / finality
  • verifiable history

PURPOSE

  • Chain-of-Custody
  • identity → authority → volition
  • consent
  • policy
  • execution
  • revocation cascades
  • evidentiary accountability

The stack

Identity proves who an actor is. AVC proves what it may pursue. EXOCHAIN proves what actually happened.

  1. Identity who an actor is
  2. Authority what it may invoke
  3. Volition delegated intent
  4. Consent principal grant
  5. Execution what it actually did
  6. Custody Receipt evidentiary record

Pillar 1

Autonomous Volition Credentials

Portable, signed, machine-verifiable credentials that declare what an autonomous actor is authorized to pursue before it acts. Validation is fail-closed. Delegation strictly narrows scope.

Pillar 2

Trust Receipts

Hash-chained, signed records proving identity, authority, consent, policy, action, timestamp, revocation state, and custody hash for each execution event.

Pillar 3

Zero-priced launch settlement

The economic transaction mechanism is live. Every active price resolves to 0 EXO with an explicit ZeroFeeReason. Trust is not paywalled.

For

Developers

Issue and validate AVCs. Generate trust receipts. Run a node. The Rust SDK is shipping; Node and Python are on the roadmap.

Enterprises

Stand up an organization, register actors and policy domains, issue scoped AVCs to your agents, and export deterministic audit packets.

Validators · Researchers

Operate as a custody verifier. Read whitepapers. Engage with governance and the open security disclosure program.
