That newfangled Journal thing

I usually agree with what Rainer posts, but I think he has it wrong this time. You periodically save the latest hash, not the first hash. Saving the first hash would provide no security whatsoever.

Of course, there are still complicated questions surrounding how often you save this latest hash, and whether the hashing function is strong enough and fast enough, etc.
