I do not know how to put it, but if we remove anything that happen behind those activity logs, then all things is an activity log. Same goes with the history I guess, the medical records, the bank transaction records, the employee records, and everything that people do and put on records... they are all just an activity log, that is as I stated, if we remove the thing that happened behind that activity log.
There's a difference between a transaction record and an activity log. In the first you have an asset that is being transferred between people and you write down quantities of that asset. In the second you just write down events that occur. In crypto, these events are changing numbers with wallet applications.
