Oct 1, 2025Month 2025-10 highlights: Delivered features and fixes that improve reliability, data integrity, and developer productivity across blocksense. Key features implemented include printing predicted contract addresses instead of salts, and substantial docs/spec work to merge ADFSIndexerService3 with unified versioning/topic mapping and version detection. Finality processing was enhanced with concurrent processing support and explicit L1/L2 finality modes, accompanied by improvements to queue policy. A comprehensive DB/schema and indexing refresh was performed to fix ring-buffer field types, align index naming, add optional advisory locks, and strengthen locking/guardrails. Health, retention, and operational visibility were upgraded with a stale-lock runbook, enhanced health endpoints, retention policies for dropped items, and explicit visibility for the ordering buffer. Decoder tooling and tests were also improved to bolster quality and maintainability.

Apr 1, 2025April 2025 focused on strengthening upgradeability, cross‑chain reliability, and time semantics for blocksense-network/blocksense. Key features delivered include an overhaul of the AggregatedDataFeedStore (ADFS) upgradeability architecture with bitwise index optimizations, decoupled deployment from the implementation address, and enhanced read-encoding type safety; a new upgrade task was introduced to streamline proxy upgrades. Deployment tooling was updated to align with the new upgradeable proxy and to improve smoother multichain deployments, including adjustments to the multichain deploy task. Major bug fix: a failing multichain deployment test was corrected by adjusting file paths and configuration reading methods, restoring test stability across chains. Additional improvements include time handling enhancements: CLAdapterLib timestamps are now returned in seconds, and Blocksense lib gained epoch timestamp getters (seconds and milliseconds) with tests; sports data contracts were deprecated and removed, and storage/documentation updated accordingly; Solidity compiler updated to 0.8.28 across relevant contracts for compatibility and security. Overall impact: reduced risk during upgrades, improved deployment reliability across chains, clearer time semantics for analytics and contracts, and lower maintenance burden through deprecation of outdated data feeds and a modernized toolchain. Business value is preserved through faster upgrade cycles, fewer downstream issues during deployments, and stronger security posture.
