Sep 1, 2025

September 2025 performance for starcoin (starcoinorg/starcoin) focused on delivering two major feature tracks and stabilizing the deployment/test surface, with a clear emphasis on business value: more predictable block production, stronger RPC readiness for external integrations, and scalable CI for faster iteration. Key features delivered include DAG Consensus Enhancements, delivering a DAG-based block time target with red (conflicting) and blue (uncle) blocks, improved DAG difficulty adjustment with a larger adjustment limit, genesis/config alignment, and API readiness (BlockHeader) for RPC compatibility, along with the unification of the BlockHeader API and exposure of DAG fields to RPC for external integrations. Network and CI Infrastructure Improvements were also shipped to improve peer discovery, fix build/test workflow issues, and introduce Kubernetes-based CI runner support for scalable build/test pipelines, enabling faster, more reliable validation. Major bugs fixed include prune handling improvements and network-p2p initialization/build workflow fixes, reducing failure modes and improving developer experience and reliability. Overall impact: increased block-time stability and RPC readiness enable smoother validator operations and wider external integrations, while Kubernetes-based CI runners and CI workflow improvements significantly enhance engineering velocity and scalability. Demonstrated technologies/skills include DAG-based consensus logic, RPC API design and integration, Kubernetes-based CI/CD, and robust Git/GitHub workflow hygiene.

August 2025

35 Commits • 3 Features

Aug 1, 2025

In August 2025, delivered a major DAG and multi-VM integration across Starcoin core and VM layers, consolidating DAG support across core types, VM types, open-block, BlockTemplate, chain execution, miner, and related services. Integrated DAG consensus and multi-VM transaction support, and unified BlockMetadata handling between VM1 and VM2. The work advances throughput, correctness, and maintainability by aligning DAG workflows across components and stabilizing the build and test surface.
