Verifiable human participation

We validate where humans participate.

ProofOfProcess.ai creates cryptographically verifiable evidence of human input, review, revision, approval, and decision-making across AI-assisted and digital workflows.

● VERIFIED SESSION
Human + AI Collaboration Record
ML-DSA signed · timestamp anchored
01
Human Input Typed prompt, direction, source material, or decision captured.
02
AI Output Model response or generated artifact hashed and linked.
03
Human Review Edits, revisions, rejections, and approvals become evidence.
04
Tool Actions Tool intent, results, permissions, and effects are recorded.
05
Checkpoint Events are committed into an integrity-preserving Merkle root.
06
Verification Signed evidence can be independently checked without exposing everything.
How it works

Evidence for the process, not just the final file.

ProofOfProcess records the shape of collaboration: who acted, what changed, what was reviewed, what tools were used, and when each checkpoint existed.

01 / CAPTURE

Observe meaningful events

Human prompts, AI outputs, tool calls, approvals, revisions, artifact changes, and delegated actions are normalized into a common event protocol.

Capture-independent
02 / ATTEST

Cryptographically bind the record

Canonicalized events are hashed, sequenced, Merkle-committed, and signed with post-quantum attestation keys.

ML-DSA-65
03 / VERIFY

Prove selectively

Share a signed certificate that anyone can validate independently, against Bitcoin block headers, with no dependency on us.

Selective disclosure
Use cases

One protocol. Many processes.

Wherever human judgment matters, ProofOfProcess can provide a verifiable record of participation.

AI CollaborationShow where people directed, revised, accepted, rejected, or approved AI-generated work.
Software DevelopmentTrace human review of AI-written code, tool use, approvals, and contribution lineage.
Creative WorkDocument the evolution of manuscripts, songs, designs, images, and media.
Scientific ResearchBind datasets, analysis steps, revisions, approvals, and resulting publications.
Legal & ComplianceEvidence review, approval, human intervention, and procedural accountability.
EducationDemonstrate the pattern of student participation without exposing the entire work history.
ManufacturingRecord inspections, process steps, QA decisions, rework, and sign-off.
Agent AccountabilityTrace autonomous actions, permissions, tool execution, and human authorization.
Evidence strength

Participation is not a checkbox.

ProofOfProcess reports measurable evidence and attestation strength instead of pretending a single score can determine authorship.
