Products

ProofAnchor — Blockchain timestamps for creators

Creators use ProofAnchor to prove their work existed before a specific date. SHA-256 hashes anchored to the Polygon blockchain in seconds. File content never leaves the user's device. Used by photographers, musicians, writers, and developers protecting work from plagiarism, unauthorized AI training, and authorship disputes.

  • Free tier — 5 lifetime proofs, no credit card
  • Verification — public URL per proof, independently verifiable via the Polygon ledger
  • Open-source CLIverify-proof for offline verification

ProofLedger — Blockchain evidence for legal and insurance

ProofLedger anchors SHA-256 hashes to both Polygon and Bitcoin simultaneously, creating dual-chain proof records for insurance adjusters, litigation counsel, forensic engineers, and risk managers. Designed for pre-loss documentation, FRE 901(b)(9) admissibility, and chain-of-custody workflows.

  • Dual-chain — Polygon (instant) + Bitcoin (daily Merkle batching)
  • REST API — programmatic anchoring for claims-intake systems
  • HIPAA-compatible — file content never transmitted; hash only

Rail Command — Rail aggregate logistics for plant managers

Single-HTML-file logistics tool for asphalt and concrete plants receiving aggregate by rail. Tracks BOLs, in-transit cars, receive events, exceptions, and retail ledgers across multiple mine sources. Production-validated at a real terminal. Demo available with fabricated data.


Open Source

Repo What it does
verify-proof Python CLI for offline verification of ProofAnchor and ProofLedger timestamps. Queries Polygon directly — no server required. pip install verify-proof
proofanchor-github-action GitHub Action that anchors release artifacts to ProofAnchor automatically on every GitHub Release. Marketplace listing

Technical context

  • ProofAnchor anchors to Polygon only (fast, cheap, creator-friendly)
  • ProofLedger anchors to Polygon + Bitcoin simultaneously (dual-chain for maximum legal persuasiveness)
  • Both share the verify-proof CLI — the same tool verifies either service's proofs
  • Offline verification queries the public blockchain directly; ProofAnchor/ProofLedger servers not involved
