Can you point me to the place where they created mutability in
notSafecoin?

It was block 236,000 for Komodo if that's what you want to call a rollback.
Komodo block 23600 is a valid
immutable block with 528,795 confirmations, which has exactly nothing to do with a fork coin (like
notSafecoin) that started
a year after the block you posted and some centralized cliche on some random 3rd-party chat site introduced mutability into a non-Komodo chain (making it
notSafecoin), so I'm not sure what you're on about (and I'm guessing you don't know what you're on about either).
Kind of strange like trying to explain something like human behaviour to some authistic kid.
