Sure, but what I'm curious about is: is that a real problem in practice that organizations have been fighting, or is it just a problem in theory? If I told an organization, "I've built a blockchain based time tracking system that is 100% impossible to be tampered with", would they say, "oh thank goodness this is a huge problem for us!", or would they say, "oh that's sort of neat but our tampering related loss is already within acceptable bounds"? My sense is that it would be the latter.
It is not only about being impossible being tampered with. It is about trusting the system. Since we trust the blockchain with 100 + billion dollars. trusting it for a time sheet system should not be that hard
Sure, but I think you're missing my point. Is this a problem that really needs a solution or is it a solution in search of a problem? Are time tracking systems not trustworthy enough already? Perhaps I'm just ignorant, but I've never heard of this issue, and it just sounds like the sort of thing that sounds like a problem to techies, but isn't really a problem in practice.
