Thank you for this information.
I forgot that RBF opt-out was hacked on top of `nSequence`, and relative ti=
melocks were also hacked on top of `nSequence`.
In particular coins locked on mainchain for the purpose of staking a sidech=
ain (mainstake) have to be locked with an `OP_CSV`, which immediately enabl=
es this protection.
