Worked on the ssvlabs/ssv repository to upgrade the go-eth2 library dependency to its latest version, focusing on improving stability, performance, and security. The update involved modifying go.mod and go.sum files using Go’s dependency management tools, ensuring that the project leveraged new features and bug fixes from the upstream library. Emphasis was placed on maintaining reproducible builds by validating all dependencies and updating the lockfile accordingly. This work prepared the codebase for future downstream feature adoption and reduced maintenance risk. The technical approach centered on Go modules and dependency management, with no major bug fixes addressed during this period.
