You can still have the extra verifier nodes, but those don't have to be on the critical read/write path. Presumably you can create a config where have your "main" beefy server where all the activity is -- which is backed up, redundant, etc... And a bunch of "client" servers, which just pull and verify the data all the time. And the client servers notify if there are any errors using some out-of-band channel, probably using the same system you use for general server health monitoring. So you are getting same security guarantees as "private blockchain", but with drastically higher performance, and only needing one beefy server. And the downside is that you won't auto-stop all operations on tampering, you'll only get an alert for it.
