Re: Blockchain ?

No. A majority of miners can rewrite the chain. This was done, for instance, in response to the Etherium hack. For an internal blockchain, a rewrite is more-or-less trivial.

Deleting data would be very similar, I believe, to purging proprietary data out of a git repo.

Hard, but finite.
