The library splits its codebase into consensus-critical modules (opentimestamps.core.*) that define timestamp validation semantics, and application-level modules that build on them. You use it to create proofs that data was present at a given moment, and to verify those proofs later, with the guarantee that any change to the original data will invalidate the proof.\n\nThe package depends on pycryptodomex for cryptographic operations and python-bitcoinlib for blockchain interaction. It installs as a pure Python wheel with low friction. The project is in Beta status and has aged since its last release in January 2023, though the repository remains unarchived and receives occasional maintenance. No known security vulnerabilities are recorded.","worth_installing":"Yes, with conditions. Install if you need Bitcoin-backed timestamping and can accept that the package is aging (last release over a year old). The low install friction, absence of known vulnerabilities, and active repository make it viable for production use. However, verify that the consensus-critical modules remain compatible with your target Bitcoin protocol version, and test thoroughly on your Python version before deploying.
