What is IPFN?

Published 2025-01-10

The International Pinned File Number (IPFN) is an open, transparent system for digital authorship verification.

How It Works

When you certify a work with IPFN, we:

  • Compute a cryptographic hash (SHA-256) of your file
  • Pin metadata to IPFS, creating an immutable Content ID (CID)
  • Assign a unique IPFN identifier
  • Publish a verifiable certificate

Why IPFN?

IPFN provides a decentralized, immutable record of provenance for digital works, ensuring authenticity and trust in the digital realm.
