The NPPP v1 Flow
Canonicalize → Commit → Replay
NPPP v1 separates the proof engine from the verification surface. The result is
independent integrity recomputation without relying on mutable flags.
1. Construct Bundle
Artifacts are normalized into deterministic evidence bundles (UTF-8) so identical logical inputs
always produce identical bytes.
2. Compute Commitment
The notarization engine computes a SHA-256 commitment and issues a canonical, pipe-delimited
NPPP v1 proof string.
3. Replay Verify
Verification is derived from recomputation. Any verifier can retrieve the bundle
and confirm the hash matches the proof string independently.

Use Cases
Proof Infrastructure for the AI Era
UserMint is designed for systems that need deterministic proof of integrity without relying on
trust-based validation or centralized verification state.
AI Model Provenance
Prove model artifacts, datasets, and configurations were not altered after generation or release.
Audit & Compliance
Generate replay-verifiable proofs for reports, filings, logs, and internal controls.
Legal & Evidentiary Workflows
digital artifacts with deterministic proof that can be independently verified later.
Supply Chain Integrity
Anchor product records and operational data to proof bundles that support downstream verification.
News & Media Verification
Prove that source artifacts and published records match the committed canonical bundle.
Developer Systems
Integrate deterministic proof generation into CI/CD pipelines, APIs, and internal data flows.
