Git and QLDB both use the Merkle tree concept to prove that history hasn't been edited. The GPG signing proves new events are coming from a trusted person or computer.
Thanks. (I'm actually aware of the mechanisms involved and have implemented something similar in the past, although with a rather different set of tradeoffs.)
My main interested was in use cases and the details of the integration with git.
