Audit Trail

Hedera Consensus Service — Public, immutable, privacy-preserving audit log

How the Audit Trail Works

At each critical stage of the auction lifecycle, a commitment hash is published to the Hedera Consensus Service (HCS). The commitment is computed as hash(auctionId, stage, cantonTxId, adiTxHash, timestamp, nonce). Anyone can verify the sequence and timing of events. Nobody can reverse the hash to recover bid values, prices, or terms.

Enter an Auction ID to view its public audit trail

Audit commitments are stored on Hedera Consensus Service and can be viewed on HashScan

Hiero CLI Integration

The audit trail can also be accessed via our custom Hiero CLI plugin. Install the plugin and use these commands:

# Publish a new commitment
hiero auctionlog publish \
  --stage award \
  --auction-id DEMO-XXX \
  --canton-ref <canton-tx-id> \
  --adi-tx <adi-tx-hash>
# Verify audit trail
hiero auctionlog verify \
  --auction-id DEMO-XXX

# Export as CSV
hiero auctionlog export \
  --auction-id DEMO-XXX \
  --format csv
