OpenTimestamps: A Tool for Creating and Verifying Timestamps

OpenTimestamps is a versatile tool that empowers users to generate timestamps and subsequently validate them. Timestamps serve as evidence that specific data existed before a certain point in time. While users can create timestamps in permissionless blockchain systems like Bitcoin and Ethereum, doing so typically incurs network fees. OpenTimestamps offers an alternative by employing a calendar server, which can be set up free of charge. To verify timestamps, users can simply drag and drop a file onto the OpenTimestamps website.

OpenTimestamps maintains several open-source repositories on its GitHub page. These repositories encompass libraries for popular programming languages such as Python, Rust, JavaScript, and Java. Notable repositories include the client tool, responsible for stamping files through a calendar server, and the calendar server, which handles timestamping requests from the client. These two repositories collaborate to provide timestamping functionality.

Additionally, users have the option to subscribe to a mailing list to stay informed about announcements. Several companies, including Eternity Wall, Signatura, and Cerved, currently leverage OpenTimestamps. For instance, Eternity Wall's service enables users to create eternal, uncensorable, and timestamped messages, illustrating the practical applications of OpenTimestamps.
