Proof Infrastructure: A Category Definition

Defining the category

Proof Infrastructure is the category of technology that verifies authenticated provider events and cryptographically signs each one into an independently verifiable Proof Artifact — portable, privacy-preserving evidence of what a provider reported, with payload integrity and evidence provenance, validatable without exposing the underlying data.

It is not compliance software, audit software, workflow software, or an AI governance platform, though it complements each. Its distinguishing property is the independent verifiability of the artifact: evidence anyone can confirm without trusting the party that produced it. It proves what a provider reported and that it is intact — not whether the underlying business decision was correct.

The primitives

The category rests on three primitives. A commitment binds an event to its data via a cryptographic hash, preserving privacy. A proof artifact packages that commitment with issuer authority and timing, and signs it. Independent verification confirms integrity, authenticity, authority, and timing — mathematically.

Scope and boundaries

Proof Infrastructure proves the facts of what happened; it does not judge whether a decision was correct or a policy was wise. That boundary is deliberate: by focusing on verifiable facts, it provides a neutral foundation that other systems — audit, compliance, governance — can build upon.
