What is Trust Ledger?
A tamper-evident record of every consequential action and the reasoning and approval behind it.
Trust Ledger: definition
As AI takes on more consequential actions, "trust me" is not good enough - you need a durable record of what was decided, why, and who signed off. A trust ledger provides that: an append-only, tamper-evident log where each significant action (by a human or an AI agent) is recorded with its context, rationale, and approval. It turns governance from policy on paper into evidence you can produce.
- Append-only and tamper-evident - entries cannot be quietly altered
- Records the actor (human or AI), the action, the reasoning, and the approver
- Turns governance claims into producible evidence
- The audit substrate for AI action governance and compliance
How Fintra handles it
Fintra maintains a trust ledger across the platform via SentriAI: every consequential action - an AI-drafted journal entry approved by a controller, a payment released, a hiring recommendation accepted - is recorded with its reasoning and the named human who approved it. This ledger is what makes SOC 2, HIPAA, and EU AI Act evidence a query rather than a scramble.

Frequently asked questions
What is the difference between a trust ledger and an audit trail?
An audit trail records what happened; a trust ledger emphasizes tamper-evidence and captures the reasoning and approval behind consequential decisions - including AI actions - so the record can establish trust under scrutiny. A trust ledger is a stronger, governance-oriented form of audit trail.
Why do AI systems need a trust ledger?
Because AI increasingly takes consequential actions, and stakeholders - auditors, regulators, customers - need to verify what was decided, why, and who approved it. A tamper-evident trust ledger converts governance from assertion into evidence.
What makes a ledger tamper-evident?
It is append-only and cryptographically or structurally protected so that altering or deleting past entries is detectable. This means the record you produce for an auditor can be trusted not to have been quietly edited after the fact.
Does Fintra maintain a trust ledger?
Yes. Via SentriAI, Fintra records every consequential action across finance, HR, and security with its reasoning and named approver in a tamper-evident trust ledger - which is what makes compliance evidence a query rather than a manual scramble.
