Story Form

As a BN Developer
I want to keep Hashing consistency with CN
So that we implemeent the latest changes to the way we calculate the BlockRoot Hash

Technical Notes

There are on-going conversations in how to make the Block Root Hash resistant to a certain type of attack that allow a malicious entity to prove things that does not exist by replacing a leaf with another sub-tree, for this, once the changes are approved and implemented by the CN, we need to update BN hashing algorithm to use the same.
