Cryptographically Verifiable
Software History

Prove — in zero knowledge — that your code, builds, and artifacts come from exactly the source you claim. No trust in CI providers. No source disclosure. Just math.

The Software Supply Chain Is a Trust Problem

Current systems rely on process rather than cryptographic proof, leaving critical gaps in verification.

  • Git hashes verify history, but not the integrity of builds or artifacts

  • CI pipelines require blind trust in operators and infrastructure

  • Closed-source components break transparency while open-source risks exposure

  • Audits rely on manual processes rather than cryptographic proof

Zero-Knowledge Proofs for Version Control

Cryptographic guarantees without compromising privacy or security.

  • Maintains standard Git workflows (SHA-256) while adding cryptographic proofs

  • ZK proofs cryptographically link commit → history → build → artifact

  • Proofs reveal nothing about private code or build internals

Commit → Proof → Artifact

How VeriSource Works

Cryptographic verification at each stage of the software lifecycle.

1. Commit Anchoring

Commits are verified as belonging to a known repository history with cryptographic proofs.

2. Deterministic Build Proofs

Prove the artifact was built from that commit with specific constraints and dependencies.

3. Test Verification

Prove tests executed and passed — without exposing tests or logs.

4. Verifiable Artifact

Ship binaries with cryptographic proofs anyone can verify independently.

Built for High-Assurance Software

Where cryptographic verification matters most.

Supply-Chain Security

Prevent CI compromise and malicious injection with cryptographic proofs.

Hybrid Open/Closed Source

Prove open-source inclusion while protecting proprietary IP.

Regulated Industries

Replace audits and attestations with cryptographic proofs for compliance.

On-Chain & Critical Deployments

Prove deployed code matches reviewed source without disclosure.

Trust the Proof, Not the Process

Zero-knowledge cryptography provides verifiable trust without compromise.

No CI Trust

Eliminate reliance on CI operators and infrastructure.

Source Protection

No source code disclosure required for verification.

No Secret Leakage

Proofs contain zero knowledge about sensitive data.

Verifiable Forever

Proofs remain valid indefinitely with no ongoing trust.

Proof-First Software

"Signatures prove identity. Logs prove nothing. Proofs prove correctness. We believe the future of software trust is cryptographic, not procedural."
