Over a three-month period, Chen Wang enhanced the okx/xlayer-erigon and 0xPolygonHermez/cdk-erigon repositories with a focus on backend performance, concurrency, and maintainability. He optimized transaction pool logic by introducing RWMutex-based concurrency control and refining transaction sorting, which improved throughput and reduced race conditions. Leveraging Go and Docker, he modernized build systems and upgraded toolchains for better security and compatibility. His work included atomic caching for gas prices, efficient big integer handling using unsafe memory operations, and streamlined database interactions. These contributions resulted in faster transaction processing, lower latency, and a more robust codebase, reflecting deep technical understanding and careful implementation.

March 2025: Performance- and safety-focused enhancements for okx/xlayer-erigon. Delivered two major feature sets with clear business value: (1) Transaction Pool Concurrency and Base Fee Logic Improvements to reduce contention and race conditions, and (2) BigInt Conversion Performance Optimizations for faster data handling. Implementations include a RWMutex-based concurrency model, a read-only bestRead path, a goroutine to prune unsupported transactions, refined base-fee and tip calculations, and unsafe-memory-based optimizations with dedicated benchmarks and tests. These changes collectively improve throughput, reliability under load, and runtime efficiency while maintaining correctness.
