ParallelEVM: Operation-Level Concurrent Transaction Execution for EVM-Compatible Blockchains

Blockchain systems, especially EVM-compatible ones that serially execute transactions, face a significant limitation in throughput. One promising solution is concurrent transaction execution, which accelerates transaction processing and increases the overall throughput. However, existing concurrency control algorithms fail to obtain adequate speedups in high-contention blockchain workloads, primarily due to their transaction-level conflict resolution strategies.
