Nov 1, 2025November 2025: Delivered core live-data and reliability improvements for logos-co/nomos across SDP, transaction, and data sampling services. Key outcomes include replacing the SDP mempool mock with a real adapter and cleaning up unused mock backend code, enabling interaction with a live mempool and reducing maintenance overhead; enabling real-time transaction subscriptions from data availability sampling to improve responsiveness; and introducing multi-session historic sampling with session-change fallback and integrity checks to ensure correctness during transitions. These changes jointly reduce maintenance costs, improve event latency and data integrity, and strengthen end-to-end reliability for live transaction processing.

Jul 1, 2025July 2025 monthly summary for logos-co/nomos: Core delivery focused on boosting testability, data reliability, and architectural modularity for the DA network. Implemented a dedicated HTTP testing API server behind a feature flag with new testing endpoints and CI/workflow updates to support robust integration testing of the membership service. Enabled historical membership retrieval for subnetworks and integrated address books into membership storage with API endpoints to fetch DA membership details. Refactored the DA network architecture by rehoming the API adapter to the DA-network layer and separating address book management from membership logic to improve modularity and maintainability. Introduced RocksDB-backed persistence for DA membership information and address books, replacing mocks and ensuring durable storage across blocks. These changes collectively improve test coverage, data reliability, and deployment safety, while providing a scalable foundation for future membership features.

Jun 1, 2025June 2025 monthly summary for logos-co/nomos: Key features delivered and bugs fixed with clear business value and technical outcomes. Key outcomes include Data Availability (DA) network membership management and integration enhancements, data integrity protections, and improved error handling across the SDP subsystem. Notable improvements were achieved through new membership handling with mock adapters and enhanced configuration to support dynamic subnet membership, along with a robust guard against outdated data updates. In addition, SDP backend errors were refactored using thiserror for idiomatic error handling, and the test suite was hardened by aligning panic expectations for polynomial degree validation. These changes collectively reduce operational risk, speed up integration testing, and improve maintainability.
