Description

Currently, verify_and_charge is responsible for transaction verification using state from tries. We can improve throughput by running this verification step in parallel.

It only need read-only access to those tries, and changes can be applied after joining the threads.

A potential solution would be to "freeze" the memtrie, construct Arc<FrozenArena>, and then "unfreeze" the trie after use.
