Proof.ink

Proof.ink is a blockchain-based service that enables users to prove the integrity of their files by generating a SHA256 fingerprint (hash) of any file directly in the browser without uploading it. This fingerprint can be publicly stored on the Hive blockchain to guarantee tamperproof, immutable verification of file contents at a given time, enabling anyone to validate the authenticity of files using the blockchain as a trustless public ledger. Proof.ink requires users to have a Hive account to store fingerprints via public transfers, with flexible donation amounts for maintenance.
