It's a PR based on #33097
In this PR, the Database interface in
core/statehas been extended with onemore function:
With this additional abstraction layer, the implementation details can be hidden
behind the interface. For example, state traversal can now operate directly on
the flat state for Verkle or binary trees, which do not natively support traversal.
Moreover, state dumping will now prefer using the flat state iterator as the primary
option, offering better efficiency.
