One Proof Infrastructure. Every Enterprise System.
Convert authenticated provider events into independently verifiable Proof Artifacts the moment they occur. PFP verifies each event and signs it into portable, privacy-preserving evidence — verifiable by anyone, without exposing the underlying data.

Built on Defensible Innovation
PFP is backed by 22 filed patent applications spanning Proof Infrastructure, cryptographic verification, privacy-preserving evidence technologies, and future platform capabilities.
What it is
Proof Infrastructure — it verifies authenticated provider events and signs the result.
What it produces
Independently verifiable Proof Artifacts — portable, privacy-preserving evidence.
What it proves
That an authenticated event occurred, its payload is intact, and its provenance.
What it does not do
It does not assert business truth, approvals, compliance, or policy decisions.
What is Proof Infrastructure?
Proof Infrastructure is a foundational layer that verifies authenticated provider events and signs each one into an independently verifiable Proof Artifact.
Most systems produce evidence you are asked to trust — logs, exports, and reports controlled by a single party. Proof Infrastructure produces independently verifiable Proof Artifacts that any party can check, mathematically, without trusting the source and without exposing the underlying data. It proves that an authenticated event occurred and was not altered — not whether the underlying decision was correct.
Read the definitive guideA verification layer
Sits alongside your systems and turns their authenticated events into portable, verifiable Proof Artifacts.
Deterministic artifacts
The same authenticated event always produces the same verifiable Proof Artifact — no ambiguity.
Privacy-preserving
Commits to the payload with cryptography; the underlying data is never exposed.
Independently verifiable
Any party can verify a Proof Artifact without contacting or trusting the issuer.
Authenticated event to Proof Artifact to independent verification
Three steps turn an authenticated provider event into portable evidence anyone can independently verify.
Authenticated event
An authenticated provider event occurs
An authenticated event arrives from a provider you already use — a signature completion, a payment, an authentication, an issue transition, or an AI action — carrying a payload PFP can verify.
Proof Artifact
PFP verifies it and signs a Proof Artifact
PFP verifies the authenticated event, commits to its payload, and cryptographically signs the result into a Proof Artifact — capturing what the provider reported and its provenance, without exposing the underlying data.
Independent verification
Anyone can independently verify the artifact
Auditors, regulators, partners, or AI systems verify the Proof Artifact independently — confirming the event occurred, its payload is intact, and its provenance — without trusting any central party.
What PFP does — and what it does not do
Precision is the point. PFP proves the facts of an authenticated event so that other systems, teams, and regulators can make the judgments that depend on them.
What PFP does
- Proves that an authenticated provider event occurred.
- Proves payload integrity — that the event data has not been altered.
- Establishes evidence provenance — where the event came from and who issued it.
- Signs each event into a portable, independently verifiable Proof Artifact.
- Preserves privacy by committing to data rather than exposing it.
What PFP does not do
- It does not assert business truth or that an outcome was “right.”
- It does not decide whether an approval was authorized or valid.
- It does not certify compliance with any regulation or framework.
- It does not judge whether a workflow was correct or complete in business terms.
- It does not make or evaluate policy decisions.
In short: PFP proves what a provider reported and that it is intact — the verifiable foundation your auditors, regulators, and governance teams build their judgments on.
Evidence today is asserted, not verifiable
Across finance, healthcare, government, and AI, critical evidence is produced and controlled by a single party — and cannot be independently checked by anyone who was not there.
Evidence you have to trust
Logs, screenshots, and exported reports can be edited, deleted, or fabricated. Nobody can independently confirm they reflect what a provider actually reported.
Unaccountable AI actions
AI systems act with no verifiable record of what event occurred, when, by which model, or with what payload.
Verification vs. privacy
Proving an event happened often means exposing sensitive data. Redacting it destroys verifiability and provenance.
Trust across parties
When multiple organizations are involved, no single log is authoritative and reconciliation is slow and disputable.
Proof Infrastructure applies wherever evidence must be independently verifiable
Inspect and verify a Proof Artifact
Pick an authenticated event type, inspect its Proof Artifact, and run independent verification — the way an auditor, regulator, partner, or AI system would.
Only a cryptographic commitment to the authenticated event payload is stored. The underlying data is never exposed inside the Proof Artifact.
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
Verify an event. Sign a Proof Artifact. Verify it anywhere.
A simple, deterministic model: pass an authenticated provider event to generate a signed Proof Artifact, then verify it anywhere — no shared secrets, no central authority.
// 1. Sign an authenticated provider event into a Proof Artifact const proof = await pfp.generate({ type: 'proof_of_provider_event', commitment: sha256(event), // payload stays private issuer: 'provider:docusign/org:northbank', }); // 2. Anyone can verify — no trust in the issuer const result = await pfp.verify(proof); console.log(result.verified); // true

Wherever an authenticated event must be independently verifiable to another party, Proof Infrastructure applies.
Evidence an AI decision event occurred
Produce a verifiable Proof Artifact of which model recorded which decision, when, and with what payload — for AI accountability and provenance. It evidences the event, not whether the decision was correct.
Evidence an approval event was recorded
Turn an authenticated sign-off event from a provider into a Proof Artifact regulators and partners can verify independently — proving the event and its integrity, not that the approver was authorized.
Evidence a workflow event ran
Capture authenticated events from each step of a process as independently verifiable Proof Artifacts — evidencing that the steps were reported, without asserting the workflow was business-correct.
Verifiable evidence without exposure
Give auditors independently verifiable Proof Artifacts built on cryptographic commitments instead of raw sensitive data — portable evidence they can check for themselves.
