Data Provenance & Global Consensus

This document clarifies how ABS Core™ validates off-chain data and maintains governance integrity without a centralized SaaS authority.

The Governance Oracle

ABS Core™ implements a Sovereign Oracle Pattern to validate external metrics (API costs, token usage, compliance scores).

1. Sourcing: Data is ingested via signed payloads from trusted environments (TEEs).
2. Consensus: In multi-node deployments, a Raft-based consensus validates that all nodes see the same policy state before committing to the local ledger.
3. Witnessing: Every block of 1,000 decisions is hashed and "witnessed" by a public L1/L2 (Bitcoin/Base) to prevent local history rewriting.

Evidence Chains

Each audit entry includes:

• origin_node_id: Cryptographic ID of the executor.
• policy_hash: The specific version of the YAML policy used.
• tee_quote: Hardware attestation that the WASM kernel was unmodified.

Transparency for Acquirers

The entire provenance stack is open for technical audit during M&A due diligence. We provide pre-configured Audit Nodes that can replay the entire ledger to verify zero-tampering.
