PROFILE

Chanhongming

Chan Mingming contributed to the hyperledger/besu repository by addressing a critical edge case in gas cost computation. Focusing on backend development with Java, Chan refined the gas price validation logic within the getUpfrontGasCost method to prevent returning Wei.ZERO when gasPrice.isZero, thereby improving the accuracy of transaction fee estimation. This fix enhanced the robustness and correctness of upfront gas cost calculations, reducing the risk of incorrect fee assessments during transaction processing. Chan’s work demonstrated careful attention to reliability and correctness, with changes traceable through signed and co-authored commits, and reflected strong collaboration and code review practices within the project.

February 2026 monthly summary for hyperledger/besu focused on reliability and correctness in gas cost calculations. Key feature delivered: Gas Price Validation Fix in Upfront Gas Cost Calculation. Major bug fixed: prevent Wei.ZERO being returned when gasPrice.isZero in getUpfrontGasCost, addressing edge-case correctness and reducing risk of incorrect transaction fee calculations. Impact: improved robustness of upfront gas cost computation, leading to more accurate fee estimation, fewer edge-case failures in transaction processing, and stronger network stability. Traceability through commit: d724db88b5ac6465bbf3f0b119fe466b581cecfd (Update gasPrice check in getUpfrontGasCost method, #9896). Technologies/skills demonstrated: Java code changes in Besu, gas cost computation, code review and collaboration (signed-off and co-authored commits).
