99% of the time (and all 3 times in the blog post), there is only one source of truth for any piece of data, and state transitions are completely arbitrary. Blockchain is almost always the wrong solution.

Especially since in most of the cases where it's not-totally-insane to use, the right solution is the classic distributed database which came first, where the ledger is among predefined/controlled node-membership... as opposed to a bloated mass of workarounds-upon-workarounds to make it survive being ungovernable.

I've seen some boosters pivot to saying "private blockchain", but that's a vapid marketing-lie, a contradiction like selling "single-user Twitter" when really it's just a blog.
