About IPFN

Building trust and provenance for the open Internet.

Create. Certify. Connect.

Our Mission

The International Pinned File Number (IPFN) is an open, transparent system for digital authorship verification. It provides a decentralized, immutable record of provenance for digital works, ensuring authenticity and trust in the digital realm.

We believe in an open Internet where creators are empowered with tools to prove authorship, protect their work, and connect with trusted communities.
