[It's a proof!](https://en.wikipedia.org/wiki/Curry–Howard_correspondence) For each entry returned by the
historian, we can verify that `end_hash` is the result of applying a sha256 hash to the previous `end_hash`
historian, we can verify that `id` is the result of applying a sha256 hash to the previous `id`
exactly `num_hashes` times, and then hashing then event data on top of that. Because the event data is
included in the hash, the events cannot be reordered without regenerating all the hashes.
