Worked on transaction validation performance optimization in the cosmos/evm repository, focusing on backend and blockchain development using Go and the Cosmos SDK. Refactored the AnteHandler to eliminate unnecessary Geth EVM instance creation during balance checks, instead fetching balances directly from the EVM keeper. This technical approach reduced memory allocations and garbage collection pressure, resulting in faster transaction validation and improved throughput for validators and end users. The changes enabled higher transactions per second and lower latency across the validation pipeline, contributing to more efficient block processing and resource usage. No major bugs were addressed during this period, emphasizing feature delivery.
