Anchor any hash on Bitcoin and Ethereum and prove your data existed at a specific point in time. Independently, globally, and forever.
Create and verify tamper-proof timestamps with a single REST API call from your tool of choice. No blockchain expertise required.
Merkle-tree aggregation combines thousands of hashes into a single transaction, so you can timestamp anything from a few files to millions without overhead.
Every timestamp is anchored on public blockchains, so anyone can verify it at any time, even without OriginStamp.
