Validation and Commit workload throughput

Share validation and commit workload, improving resource utilization and horizontal scalability.

• The validation phase is compute-heavy as it performs multiple signature verifications.

• The commit phase is IO-heavy as it performs synchronous disk IO.

During the commit phase (IO heavy) execution, the validation phase (CPU heavy) does not execute, and vice-versa. The validator cannot validate block (𝑁+1) while block (𝑁) is being committed because the state updates performed during the commit could make the validator read stale or incomplete state.
