About Certiphy.io

Certiphy gives creators a simple, verifiable proof that their content existed at a given time, and that it is theirs. CERTIFY ANYTHING • Photos, videos, PDFs or any file, straight from your library or the Files app • Plain text: an idea, lyrics, a script • Your Instagram posts: connect your professional account and certify a post in one tap, or right after you publish it HOW IT WORKS Certiphy computes a SHA-256 fingerprint of the exact bytes of your content and records it on the Solana blockchain. Your certificate shows the fingerprint, the on-chain address, the owner and the date. Anyone can check a file against it on certiphy.io: same file, same fingerprint. KEEP YOUR PROOF The document you certified stays available in the app and can be exported to Files at any time, so you always hold the exact file that matches your certificate. PRIVACY Only the fingerprint is written on-chain.…
