Assay Public Ledger

Append-only record of verified AI evidence bundles (Proof Packs)

How to verify any entry

Every row is a fingerprint of a signed Proof Pack. To independently verify:

pip install assay-ai
assay verify-pack ./path/to/proof_pack_dir/

# The pack_root_sha256 in your verify_report.json
# should match the hash shown in this ledger.

The ledger only stores attestation pointers (SHA-256 fingerprints), not the evidence itself. The pack author holds the original pack. If they share it with you, you can verify it matches the ledger entry by comparing pack_root_sha256.
