Mandact — The Trust Layer of the Agent Economy

Product · OMP/1 — EVIDENCE

Every action provable — for internal audit, supervisors and disputes.

The Evidence Vault chains mandate, verification, action and outcome into a tamper-evident evidence chain — qualified eIDAS timestamps once a trust service is connected.

The problem

An agent operator's logs are one-sided and of little value in a dispute. The Evidence Vault produces evidence both sides can use: hash-chained, exportable — qualified timestamps once a trust service is connected.

Append-only, hash-chained

Every entry references the previous one. Later changes are technically detectable — not merely forbidden by policy.

Qualified timestamps (planned)

Planned: daily anchoring of the root hashes through a qualified trust service provider (after live validation). What evidentiary effect this has in a given case depends on the service, the use and the jurisdiction.

Frequently asked questions

+Who can see the evidence?

Both sides of the respective transaction — principal and verifier — each only for their own transactions.

+Does the vault replace our own logging?

It adds the two-sided evidence layer to it. Internal logs stay with you.
