Simple Proof
Bitcoin-anchored document timestamping and verification for governments and institutions using OpenTimestamps.
Why We Recommend Simple Proof
Simple Proof uses the Bitcoin blockchain as a neutral, uncensorable timestamp authority to prove document immutability. The service is built on the OpenTimestamps open source protocol, ensuring interoperability and avoiding proprietary lock-in. Anyone can verify documents independently using open source software, providing transparency without relying solely on Simple Proof's infrastructure.
The company has demonstrated real-world credibility through high-profile government implementations. Screven County, Georgia became the first U.S. county to secure election results on Bitcoin using Simple Proof's Immutable Proof Service in 2024. The platform was also used in Guatemala's presidential election to preserve official results, and has partnerships with El Salvador's Ministry of Foreign Affairs and National Registry for securing public records.
Simple Proof has received backing from Ego Death Capital in a pre-seed funding round announced in January 2025, signaling institutional investor confidence in the platform's approach to data integrity.
Best For
Simple Proof is ideal for governments, public institutions, and organizations that need to prove the authenticity and timestamp of critical digital records. Election officials can use it to create immutable proof that results have not been tampered with after certification. Government registries can secure birth certificates, property records, and other vital documents against future disputes about authenticity.
The platform serves organizations that require transparent, verifiable proof of document integrity without relying on centralized authorities. Because verification can be performed independently using open source tools, it appeals to institutions that value auditability and want to avoid vendor lock-in. The focus on democratic governments and transparency makes it particularly suited for public sector applications where trust and accountability are paramount.
