Definition
Proof of Execution is a Proof Artifact (or linked set of artifacts) capturing the authenticated events emitted as a process runs: each step reports an event, and the linked artifacts establish that those events were recorded, their payloads are intact, and their order. It turns "the workflow says it completed" into "here are independently verifiable Proof Artifacts of the events it reported."
This is especially valuable for regulated and cross-organization processes, where it is not enough to assert that a step ran — you need portable evidence of the events, verifiable by someone who was not there. Whether the process was correct or complete in business terms is a judgment made on top of this evidence.
Why it matters
Processes report events that later get disputed. Proof of Execution makes the reported step events and their order verifiable, rather than a claim you must trust.
- It evidences that each expected step event was recorded, not merely claimed.
- It establishes the order in which step events were reported.
- It gives auditors event-level Proof Artifacts instead of sampled trust.
- It supports SLA and contractual evidence with verifiable events.
Real-world examples
KYC onboarding completed in full
A four-step KYC workflow emits proof of execution confirming all steps ran, so a regulator can verify the process completed without seeing the customer’s documents.
Data deletion request fulfilled
A privacy request pipeline proves each deletion step executed, evidencing that a "right to erasure" request was actually carried out.
Multi-party settlement pipeline
Each stage of a settlement emits a proof; together they prove the pipeline executed end-to-end across organizations.
Visual explanation
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.

Proof of Approval
Proof of Approval is a Proof Artifact providing independently verifiable evidence that an authenticated provider recorded an approval event — establishing the event, its payload integrity, and its provenance, not whether the approver was authorized or the approval valid.
