Blockchain enabled timestamps for media files. Proof of ownership, proof of integrity, and proof of existence on mobile devices.
BlockNotary Timestamp notarizes any media file, generating publicly verifiable receipt of its origin, date, authenticity, and integrity, without exposing its contents. Its uses include digital attribution, proof of existence, prior knowledge, integrity, and authenticity. Timestamp creates 100% distributed proofs using OTS (OpenTimestamps), IPFS (InterPlanetary File System) and public Bitcoin or Ethereum blockchains. Generated receipts are independently verifiable and machine-readable.
