Additionally this package provides timestamping of PGP signed Git commits, and verification of timestamps for both Git commits as a whole, and individual files within a Git repository. Requirements Python3 While OpenTimestamps can create timestamps without a local Bitcoin node, to verify timestamps you need a local Bitcoin Core node (a pruned node is fine). Installation Either via PyPi: $ pip3 install opentimestamps-client or from source: $ python3 setup.py install On Debian (Stretch) you can install the necessary system dependencies with: sudo apt-get install python3 python3-dev python3-pip python3-setuptools python3-wheel Usage Creating a timestamp: $ ots stamp README.md Submitting to remote calendar https://a.pool.opentimestamps.org Submitting to remote calendar https://b.pool.opentimestamps.org Submitting to remote calendar https://a.pool.eternitywall.com You'll see that README.md.ots has been created with the aid of three remote calendars.
