Simple Proof

Description

Simple Proof provides a document timestamping and verification service that uses Bitcoin's blockchain to create immutable proof that digital records have not been altered. Its process fingerprints (hashes) documents at the moment they are shared or published, timestamps them using open protocols such as OpenTimestamps, and allows anyone to verify authenticity via Simple Proof verification links or independent open source software. The company integrates with existing document workflows and cloud platforms, including Amazon S3 and Docusign, to embed blockchain timestamping at enterprise scale. Simple Proof has worked with governments and public sector clients, notably partnering with Screven County, Georgia in 2024 to timestamp election results on Bitcoin's Timechain, becoming the first U.S. county to secure election data this way. The company is based in Tysons Corner, Virginia, and also produces documentary content, including the film 'Immutable History,' about blockchain-based record integrity.
