May 2025 monthly summary focusing on key business value and technical achievements for 0xPolygonHermez/cdk-erigon. Highlights include throughput-focused txpool optimizations and a Go runtime upgrade with dependency updates, alongside improved test and subscription resilience.

April 2025 monthly progress across okx/xlayer-erigon and 0xPolygonHermez/cdk-erigon focusing on robustness, throughput, and maintainability. Delivered a set of feature enhancements, performance optimizations, and code simplifications that reduce latency, increase transaction throughput, and simplify future maintenance. Key outcomes include improved large-integer handling, faster gas price access, more efficient transaction processing, modernized toolchain, and streamlined database interactions.

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.
