Jan 1, 2025Summary for 2025-01 Mezo Mezod: Key features delivered: - Versioning endpoints and clientVersion across net, sidecar, and web3: added and fixed web3_clientVersion; instantiated connect client in net namespace and called Version to verify connection; return version as JSON payload; exposed version endpoint on sidecar grpc via net_sidecar. Commits: fixes and wiring across 3e2b970, 6a4dbb6, 21fa16b5, b12e56da. - Localnet scripts enhancement: integrated sidecars into localnet scripts, moved sidecar startup to its own script, and added docs; added localnet-sidecars-start makefile command. Commits: bf7a099, 46532d80, f3d4f32f. - Environment handling and configuration hygiene: scripts tolerate missing .env, added .env to gitignore, restored docker build environment docs to improve deploy hygiene. Commits: eb1b22c0, 92071bd1, b769ce550. - Mezod CLI enhancements: added --keyring-dir flag to mezod start and mezod init for better security and configuration isolation. Commit: eca40e9c7390ad77. - Bridge Genesis and storage hygiene: added initial_btx_supply parameter in bridge genesis to initialize BTX supply; split storage for BTC and ERC assets in x/bridge keeper to improve data management. Commits: a44dad47, d0b1d6d822ce0e41. Major bugs fixed: - Connect oracle initialization and defaults: fixed initialization of connect oracle parameters and net_sidecar payload; set default time interval for connect oracle. Commits: 7625bac28e, e7103572973d172a93e9e83dd60858a8c50ffa54. - Address linter errors: fixed linter issues surfaced in address-related code. Commit: ac636b4826f686245cfd6419874984d7cd7021cb. - Prevent unsafe/default values from oracle configuration: blocked bad defaults from being used.

Commit: a15e1f9a2cbee4a3eac285d5f2dff7c415b95660. - Tests updated for bridge assertions: updated tests to account for bridge-related assertions. Commit: 3d06465aba3ae181cca2a30010c3479a3cd540e2. Overall impact and accomplishments: - Increased reliability and developer efficiency through standardized versioning checks, safer configuration practices, and easier localnet testing with sidecars. New bridge genesis parameters and asset storage separation improve auditability and asset accounting. CLI enhancements streamline scripts and security practices. Environment hygiene improvements reduce setup friction and deployment risk, supporting faster onboarding and more predictable deployments. Technologies and skills demonstrated: - Go, protobuf linting and formatting, and protobuf tooling (proto-all) to enforce code quality. - gRPC/sidecar integration and REST-like JSON endpoints for versioning. - Shell scripting, localnet automation, and Makefile-based workflow improvements. - Docker build environment documentation and Git hygiene (env handling, ignore rules). - Code review application and static analysis to address lints and test robustness.
