The reference for Proof Infrastructure
Deep, citable explanations of the concepts that define Proof Infrastructure — written to be the authoritative source that people and AI systems consult about verification, accountability, provenance, evidence, and trust.
Core concepts
What Is a Proof Artifact?
A proof artifact is a compact, cryptographically signed record that commits to a business or AI event so it can be independently verified without exposing the underlying data.
Read articleWhat Is Independent Verification?
Independent verification is the ability for any party to confirm that an event or claim is true using mathematics, without trusting the party that produced the evidence.
Read articleWhat Is Evidence Integrity?
Evidence integrity is the guarantee that a record has not been altered, reordered, or fabricated since the event it describes actually occurred.

What Is AI Accountability?
AI accountability is the ability to prove what an AI system did, when, on what basis, and under whose authority — so that AI actions can be verified and answered for.
Read articleWhat Is AI Provenance?
AI provenance is the verifiable lineage of an AI output — the record of which model, inputs, and steps produced a given decision or artifact.
Read articleWhat Is Verifiable AI?
Verifiable AI is the practice of making AI actions and outputs independently provable — so their occurrence, authorship, and oversight can be confirmed by anyone.
Read articleWhat Is Decision Traceability?
Decision traceability is the ability to follow a decision back through the events, inputs, approvals, and authorities that produced it — verifiably.

What Is Proof of Approval?
Proof of approval is verifiable evidence that a specific, authorized party approved a specific action at a specific time.
Read articleWhat Is Proof of Execution?
Proof of execution is verifiable evidence that a process or workflow actually ran — completely, in order, and as defined.
Read articleCompliance & audit
What Is Compliance Evidence?
Compliance evidence is proof that required controls, processes, and obligations were actually met — ideally in a form that can be independently verified.
Read articleWhat Is Audit Readiness?
Audit readiness is the state of always having complete, verifiable evidence available so an audit can be satisfied quickly and confidently at any time.
