What does a blockchain offer in this case that submitting a line to some sort of B2B logging API where the logs are made public (like certificate transparency) doesn't?

There was that one time when /pol/ gathered information that lead to a russian airstrike on some faction in syria.

Yeah, the seccomp limitation that it can't deref pointer arguments makes things a lot less elegant than pledge.

But at least unveil can be implemented via mount namespaces.
