What is IPFN?

The International Pinned File Number (IPFN) is a decentralized registry that creates an immutable record of digital authorship. By combining IPFS content addressing with SHA-256 fingerprinting, we provide cryptographic proof of when you created something and that you are the original author.

IPFN certificates are permanent, verifiable, and cannot be altered or removed. They serve as a trusted source of provenance for creators, publishers, and anyone who needs to verify the authenticity of digital content.
