Digital notebooks (Electronic Lab Notebooks --- ELNs) exist, but haven't caught on yet.

Many researchers often need to be able to note down arbitrary diagrams, not just text, in real time, which pretty much means low-latency tablet with stylus. This became feasible in just the last decade or so.

Many ELNs do implement published hashes for verification ("trusted timestamping").

I personally understand better my own ideas (it souds weird i know) when i draw graphics and diagrams, that can be done quickly and easily on paper.
