Worked on performance and data-management enhancements for ChainSafe/lodestar, focusing on the Ethereum beacon node ecosystem. Developed offload-enabled blob APIs and improved data retention policies, introducing features like engine_getBlobsV2 and engine_getPayloadV5 to optimize blob publishing and offload cell proof computation. Implemented pruning of expired data column sidecars and aligned retention policies to improve storage efficiency. Addressed custody enforcement by fixing sequence tracking and enforcing custody requirements, adding safeguards for metadata changes. Utilized TypeScript, Node.js, and SSZ serialization to deliver these improvements, resulting in reduced compute load, enhanced data integrity, and greater scalability for the Lodestar codebase.
