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.
Upload your work
Submit the digital file itself — the exact bytes are what get certified.
Fingerprint
A SHA-256 hash of the exact file — a fingerprint no other file can share.
Pin
The record is pinned to IPFS under a content-derived Content ID (CID) — the address is the file’s own fingerprint.
The number
An International Pinned File Number — the work’s stable public address.
