01 / What it does

What it does

OpenTimestamps Client creates and verifies timestamp proofs that can be anchored in Bitcoin. A proof shows a data commitment's timing under the protocol, not ownership or authenticity of the original document. Keep the original data and proof file together, and review the verification instructions.
