Trust your data. Know what's true.

Truestamp commitments attest to the timestamp, integrity, and provenance of your most important data by cryptographically binding it to public blockchains.

Verifiable timestamps

Whether intellectual property, media files, documents, or business critical data, you'll need to prove when it first existed with a timestamp.

By binding your data to multiple public blockchains you can provably link it to on-chain transactions that commit your data to a window in time.

Submit Item user interface

Provably tamper resistant

Truestamp commits a privacy preserving hash, or fingerprint, of your data to on-chain transactions. Even single bit changes to the original data are enough to invalidate the commitment.
