docuProof — Blockchain-Anchored Proof – Timestamped, immutable file verification

Summary: docuProof generates a unique hash of any file and anchors it permanently to the Bitcoin blockchain, providing an immutable timestamp as proof of existence without uploading the file. This ensures files can be verified as unaltered and existing at a specific time.

What it does

It creates a local hash of a file and records that hash on the Bitcoin blockchain, producing a certificate that proves the file’s existence at a precise moment. The file itself never leaves the user’s device.

Who it's for

Users needing verifiable proof that a file, photo, or document existed unchanged at a certain time, such as creatives or legal professionals.

Why it matters

It prevents disputes over file authenticity by providing tamper-proof, math-based timestamps that cannot be altered or backdated.
