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).
