Right, but you can have entries in a block chain that indicate previous entries are no longer valid, or have modifications. Calculating a final state by walking through all the blocks in the chain. ( A bit like a CQRS based system can have a particular state at a point in time by replaying all events up to that point)

Doing it in such a way also makes auditing what’s happened much easier since changes are inherently reflected in the chain. You want to know when (or by who if you keep that information) a record changes, it’s right their in the chain.

If you are on Linux locally, you could try using sshfs, to “mount” the remote system to your local one and use your local dev tools. Though I suspect that would be against the spirit of what company is hoping for.
