Batch
Signature Hash

All decisions in this batch are compressed into a single cryptographic commitment. Any modification produces a different root — making tampering detectable.

Step 03
Post-Quantum Signature
AlgorithmML-DSA-65 (FIPS 204)
Signature Valid
SigHash Match
Verification Reason

Signed with ML-DSA-65, NIST FIPS 204. Resistant to quantum computing attacks. The signature cryptographically binds the forest root to this oracle's identity.

Storage Tier
Verification Source

Written to Hedera Consensus Service — a public, permissionless ledger governed by the Hedera Council. No single entity can alter or delete the record.
