Governance Proofs — ADR-ECO Starknet Anchoring

Audience: regulators + investors + technical-auditors

Last updated:

Governance Proofs

Every accepted ADR-ECO (Strategic Decision Record) is archived in Brain institutional memory and batch-anchored on Starknet mainnet via Poseidon-hash Merkle proof.

Proof Architecture

ADR-ECO file (Git)
  → archive_knowledge (Brain MCP)
    → Brain entry (UUID + poseidon_hash)
      → Batch Merkle tree
        → on-chain anchor (Starknet mainnet)
          → proof_tx verifiable on starkscan.co

Brain auto-batches entries into Merkle trees at regular intervals. Each batch produces:

  • A root_hash (Poseidon Merkle root of all entries in the batch)
  • A proof_tx (Starknet mainnet transaction, irreversible)
  • A merkle_proof per entry (membership proof in the batch tree)

Verification: any entry’s poseidon_hash + merkle_proof + root_hash + proof_tx can be independently verified against the Starknet state.

Proof Freshness

Brain processes new batch anchors at regular intervals. The time between an entry being archived and it appearing in a Starknet batch is typically under 24 hours. The lifecycle_state: batch_anchored field confirms anchoring is complete.

For real-time proof status: GET /brain/entries/{uuid}/proof-chain returns anchor.status field.
