The Evidence Ledger.
In the Receipt Economy, trust is not a feeling ΓÇö it is a cryptographic calculation. The Evidence Ledger is the immutable record of every decision, derivation, and consensus event that occurs within the Hive coordination layer.
Sealed with BLAKE3
The Hive uses BLAKE3, a cryptographic hash function that is significantly faster and more secure than MD5 or SHA-1. Every AI response, code snippet, and design file generated by the system is immediately hashed. This hash acts as a digital seal ΓÇö if a single character of the output changes, the hash no longer matches, alerting you that the evidence trail has been compromised. This ensures that the "receipt" you hold today remains valid forever.
Exportable Proof
Provenance shouldn't be trapped in our database. You can export your full evidence chain as a signed PDF or machine-readable JSON at any time. These exports include the original prompt, the model consensus scores, and the cryptographic hashes required for third-party verification.
EU AI Act Readiness
The EU AI Act requires "high-risk" AI systems to maintain detailed logging and traceability. The Evidence Ledger provides the technical infrastructure needed to comply with these transparency requirements out-of-the-box, giving your legal team a defensible audit trail for automated decisions.
