The Public Evidence Record.

Every Merkle root Veratum has anchored to Bitcoin. Public. Permanent. Verifiable by anyone, forever. This is what makes Veratum evidence trustworthy — not our word, but the Bitcoin blockchain.

Why this exists

Veratum evidence receipts are chained together into a Merkle tree. Every hour, the Merkle root of that tree is anchored to the Bitcoin blockchain via OpenTimestamps. These anchors are permanent and cannot be altered or removed — by Veratum or anyone else.

This means: if Veratum altered an evidence receipt after the fact, the anchor would no longer match the chain. Any party can detect this independently. This page shows every anchor Veratum has ever committed. It is the public record that prevents Veratum itself from being a single point of trust.

How to verify an anchor independently

You do not need a Veratum account to verify these anchors. You need:

  1. The Bitcoin transaction hash shown in any row above
  2. The OpenTimestamps library (open source)
  3. A Bitcoin node or block explorer
The verification confirms the Merkle root existed at the timestamp shown, independently of Veratum. This is the same mechanism that Certificate Transparency uses to make SSL certificate logs independently verifiable. Veratum uses it to make AI decision evidence independently verifiable.
Terminal
# Install OpenTimestamps
pip install opentimestamps-client

# Verify an anchor
ots verify merkle_root.ots

# Or verify with Veratum CLI
pip install veratum[verify]
veratum-verify --anchor <tx_hash>
