Proof of Human

    Trust, but verify.

    Agentic AI does the work. A qualified human stands behind it, and SanctifAI Trust seals that into a tamper-evident, on-chain Proof of Human. Every review, approval, and escalation, independently verifiable.

    Chain of Custody: Agentic work to accountable proof

    Agent acts

    Executes the workflow, calls tools, drafts the output.

    Threshold hit

    A control point fires a cryptographic challenge for a human.

    Human verifies

    A licensed reviewer is bound to the act, not just a login.

    Sealed on-chain

    A portable proof no party (not even us) can edit.

    Why SanctifAI

    Machines can do the work. Only a human can be accountable for it.

    The audit trail your regulator already trusts

    Binding law

    EU AI Act · Article 14

    Requires high-risk systems be “effectively overseen by natural persons.” Trust supplies the cryptographic evidence that oversight actually occurred.

    National framework

    NIST AI RMF 1.0

    The Manage function calls for traceability wherever human judgment mitigates risk. Trust attestations are the immutable, independently verifiable trace.

    International standard

    ISO/IEC 42001

    Expects documented oversight and retained evidence it operates as designed, supplied as a continuous, tamper-evident artifact.
