docuProof — Blockchain-Anchored Proof

Your file's alibi. Timestamped proof of any file, forever.

docuProof — Blockchain-Anchored Proof launched on March 3, 2026.

What it does

When someone claims your photo is AI-generated or your contract was edited — how do you prove them wrong? With docuProof. In 60 seconds, docuProof creates a unique hash of your file and permanently anchors it to the blockchain. That timestamp can never be faked, altered, backdated, or destroyed — not by us, not by anyone. Your file never leaves your device. Only the hash is recorded. Proof lives forever. $2.89. Code PRODUCTHUNT for one free.

In an age of AI fakes, create immutable proof your files existed. Blockchain-anchored timestamps in under 60 seconds.

docuProof creates a permanent, blockchain-anchored timestamp for any file in 60 seconds. It can never be faked, altered, or destroyed — not by us, not by anyone. Your file never leaves your device. Only a unique numeric code is recorded. The proof lives forever. $2.89. Anchored to an immutable blockchain. Cryptographic proof that can't be disputed, altered, or faked. Independently verifiable forever. AI can generate fake documents in seconds. Screenshots can be manipulated. Emails can be spoofed. Cloud providers go offline. When disputes arise, "I had it first" means nothing without proof. docuProof gives you cryptographic evidence anchored to the most secure, decentralized ledger ever…from docuproof.io
