A registry of trust for provenance on the Internet

The internet forgot who made things.We wrote it down.

Every image travels farther than its author's name. IPFN exists to fix exactly that — a public protocol that binds a work to the person who made it, in a record anyone can check and no one can quietly change. Not a marketplace, not a broker. A registrar.

The claim is deliberately narrow: authorship, on the record, from this date. The mechanics are deliberately boring: IPFS for the file, SHA-256 for the fingerprint, one committed ledger per day anchored to Base. Boring is what lasting looks like.

How a work gets on the record.

01

Upload your work

Submit the digital file itself — the exact bytes are what get certified.

02

Fingerprint

A SHA-256 hash of the exact file — a fingerprint no other file can share.

03

Pin

The record is pinned to IPFS under a content-derived Content ID (CID) — the address is the file’s own fingerprint.

04

The number

An International Pinned File Number — the work’s stable public address.
