    The ledger for AI and human work.

    Veratrace converts AI and human actions into cryptographically sealed, auditable work units across systems. Engineering, compliance, and finance operate from the same source of truth.

    Foundations of AI Work Verification

    What is Veratrace

    Veratrace is an AI governance platform that records work performed by humans, software systems, and AI agents as cryptographically verifiable records. These records allow organizations to audit automation, attribute work across systems, and produce reliable evidence for compliance and operational oversight.

    What is a Trusted Work Unit

    A Trusted Work Unit (TWU) is a tamper-evident record of a completed task. Each TWU captures the actor that performed the work, the systems involved, the inputs and outputs of the task, and a cryptographic signature verifying the integrity of the record.

    TWU Attributes

    • Actor (human, automation, or AI agent)
    • Systems involved
    • Inputs and outputs
    • Timestamp and execution context
    • Cryptographic verification

    Accountability Gap

    If you can't replay it, you can't defend it.

    AI actions, human overrides, billing events, and compliance flags — without a unified record, accountability breaks.

    One system of record for AI work.

    Step 01

    Normalize

    Transform fragmented AI and human activity into deterministic Work Units capturing actor identity, inputs, outputs, artifacts, and execution context across systems.

    Step 02

    Seal

    Cryptographically sign and hash-chain each Work Unit to prevent tampering, retroactive edits, or repudiation.

    Step 03

    Persist

    Write sealed Work Units to immutable storage with indexed retrieval and full lineage for replay and audit.

    Step 04

    Reconcile

    Programmatically match invoices, vendor claims, and internal logs against sealed Work Units to surface discrepancies automatically.

    Core Concept

    Trusted Work Units

    A Trusted Work Unit is a structured, sealed record of activity across AI and human systems. It captures inputs, outputs, decisions, and attribution — in a format engineering, compliance, and finance can rely on.

    Each record is integrity-verified at creation. No retroactive edits. No silent amendments.

    Why Veratrace Exists

    Vendors invoice for work they claim happened. We verify what did.

    Every AI vendor audit reveals the same pattern: tickets marked resolved, invoices submitted, and no structured way to verify who or what performed the work.

    As AI agents scale, the attribution gap widens. Veratrace closes it with structured, cryptographically sealed work records.

    What This Enables

    Deterministic records create operational, financial, and audit clarity.

    Financial Control

    Vendor invoices are reconciled against sealed Work Units. Discrepancies surface automatically before payment.

    Audit Readiness

    Any decision can be replayed with full execution context, actor attribution, and cryptographic integrity.

    Operational Accountability

    Every action is attributable to a human or AI agent across systems. No unverified claims. No undocumented work.
