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.

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