Turn any business event into verifiable proof
Proof Fabric Protocol generates deterministic, cryptographically verifiable proof artifacts that can be independently validated — without exposing the sensitive underlying data.
What it is
Proof infrastructure — a trust layer for verifiable evidence.

Proof Infrastructure & Independent Verification.
Problem it solves
Business & AI evidence you have to trust, but cannot verify.
Why it matters
Trust should be verifiable — by anyone, without exposing data.
What is Proof Infrastructure?
Proof Infrastructure is a foundational layer that transforms events, decisions, approvals, workflows, transactions, and AI actions into independently verifiable proof.
Most systems produce evidence you are asked to trust — logs, reports, and records controlled by a single party. Proof Infrastructure produces evidence that can be independently verified by anyone, mathematically, without trusting the source and without exposing the sensitive data behind it.
Read the definitive guideA trust layer
Sits alongside your systems and turns their events into portable, verifiable proof.
Deterministic proof
The same event always produces the same verifiable artifact — no ambiguity.
Privacy-preserving
Commits to data with cryptography; the underlying data is never exposed.
Independently verifiable
Any party can validate a proof without contacting or trusting the issuer.
Event to Proof to Verify
Three steps turn something that merely happened into something anyone can independently confirm.
Event
A business event happens
An approval, transaction, workflow step, decision, or AI action occurs inside your systems — exactly as it does today.
Proof
A proof artifact is generated
PFP deterministically produces a cryptographically signed proof artifact that commits to the event — without exposing the underlying sensitive data.
Verify
Anyone can independently verify
Auditors, regulators, partners, or AI systems validate the proof independently — confirming what happened without trusting a central party.
Trust today is asserted, not verified
Across finance, healthcare, government, and AI, critical evidence is produced by the very party that benefits from it — and cannot be independently checked.
Evidence you have to trust
Logs, screenshots, and reports can be edited, deleted, or fabricated. Nobody can independently confirm they reflect reality.
Unaccountable AI actions
AI systems make decisions with no verifiable record of what happened, when, by which model, or under whose authority.
Compliance vs. privacy
Proving compliance often means exposing sensitive data. Redacting it destroys verifiability.
Trust across parties
When multiple organizations are involved, no single log is authoritative and reconciliation is slow and disputable.
Proof Infrastructure applies wherever trust must be verifiable
Inspect and verify a proof artifact
Pick an event type, inspect the proof artifact, and run independent verification — the way an auditor, regulator, partner, or AI system would.
Only a cryptographic commitment to the event is stored. The sensitive underlying data is never exposed inside the proof.
Data commitment integrity
Recompute hash · matches commitment
Cryptographic signature
ed25519 signature is valid
Issuer authorization
Issuer key is authorized & active
Temporal anchor
Timestamp is anchored & consistent
Generate proof. Verify proof.
A simple, deterministic model: commit to an event to generate a signed proof, then verify it anywhere — no shared secrets, no central authority.
// 1. Generate a proof from a business event const proof = await pfp.generate({ type: 'proof_of_approval', commitment: sha256(event), // data stays private issuer: 'org:northbank/treasury', }); // 2. Anyone can verify — no trust in the issuer const result = await pfp.verify(proof); console.log(result.verified); // true

Wherever an event, decision, or process must be provable to another party, Proof Infrastructure applies.
Prove an AI decision occurred
Generate a verifiable record of which model made which decision, when, and under whose oversight — for AI accountability and governance.
Prove an approval happened
Turn sign-offs and authorizations into proof of approval that regulators and partners can verify independently.
Prove a workflow executed
Confirm that every required step in a process ran, in order, without exposing the underlying business data.
Prove compliance without exposure
Demonstrate that controls were followed using cryptographic commitments instead of raw sensitive data.
