Jan 1, 2026January 2026 (Month: 2026-01) – kaiachain/kaia: Delivered API surface stabilization and robust transaction balance validation. Key work includes exposing eth_config as public API types to improve integration, and a comprehensive overhaul of balance verification for transactions to improve error handling, ensure gas sufficiency, support fee delegation, and unify checks for fee payers and senders, with added overflow and value checks. These changes enhance API reliability, reduce failed transactions due to balance errors, and improve maintainability with standardized checks and clearer error signaling (e.g., vm.ErrInsufficientBalance). The work lays groundwork for Osaka-context resilience and easier API consumption.

Dec 1, 2025December 2025 Monthly Summary — kaia/kaia Summary: Delivered a comprehensive blob-centric upgrade to the Kaia stack, driving business value through improved correctness, performance, and observability. The work aligns with Kip-279, EIP-4844, and governance expectations while expanding capabilities for blob-enabled transactions and metrics. The month emphasized delivering tangible features, hardening critical paths, and expanding testing coverage to reduce risk in production. Key features delivered: - Blob transaction size calculation and validations: Added SizeWithoutBlobTxSidecar, fixed duplicate Sidecar calculation of tx.Size, and implemented end-to-end tests/validations for size without blob sidecar (validated via validateBlobTx). - Extended GetTransactionReceipt RPC with blob metrics: Included blobGasUsed and blobGasPrice, with tests covering blobTx receipt scenarios. - BLOBBASEFEE opcode and blob-related parameters: Implemented BLOBBASEFEE, reduced max blobs per block to 1, and adjusted blobBaseFee base value for clearer economic signaling. - CalcBlobFee interface refinement: Changed CalcBlobFee to accept only baseFee, simplifying fee computation and reducing error surfaces. - Kip-279 alignment and gas accounting: Added Kip279 validation and gas charging logic in TransitionDb; introduced related tests. - Exposure of blobBaseFee and related controls: Exposed blobBaseFee in txpool fields to improve visibility and tuning capabilities. - Blob sidecar integration and consensus refinements: Integrated blob sidecars with consensus, refactored sidecar validation/field structures, inline commit flow, and renamed/streamlined sidecar-related functions for clarity and maintainability. - Test coverage and validation improvements: Expanded the Blob Test Suite (state, block, and EIP-related tests) and added tests around Kip279/Gas and blob scenarios; added Go:generate mocks for Message interfaces. - Observability and configuration enhancements: Included blobs in metrics, added BlobScheduleConfig genesis config, and exposed blob-centric parameters for better run-time tuning. Major bugs fixed: - api_eth_test error corrected (stable test suite). - Linter errors addressed to maintain clean CI results. - Corrected VerifyEIP4844Header placement in the validation flow for robust ordering. - Prevented nil panic in CalcBlobFee (stability under edge cases). - Enforced correct fork/validation order (fork check before blob check). - Ensured single error return when applicable to simplify caller handling. - Miscellaneous refactors to improve consistency and reduce flaky test signals. Overall impact and accomplishments: - Increased reliability and predictability of blob-related operations, improving cost accounting, validation, and governance alignment. - Expanded feature surface for blob-enabled transactions, with end-to-end testing and RPC visibility, enabling safer rollout and operator tuning. - Improved performance and maintainability through caching, refactors, and standardized naming/flows across the blob path. Technologies/skills demonstrated: - Go language, RPC development, and blockchain-sidecar integration. - Kip-279 and EIP-4844 standardization and alignment. - Extensive test engineering (unit, integration, EIP coverage) and Go:generate mocks. -Code quality improvements (linter fixes, refactors, clearer naming, and error handling).
