April 2026 monthly summary for polkadot-fellows/runtimes: Focused on delivering higher Polkadot runtime throughput and stabilizing block production. Delivered a Block Production Throughput Enhancement that enables multiple blocks per slot and updated runtime configuration to increase network capacity. Addressed infrequent block building and collator log issues (e.g., 'Slot must increase') and aligned work with Release 2.2.2. Result: higher throughput, improved network scalability, and more efficient block production across the Polkadot network.

January 2026 monthly summary for paseo-network/runtimes focusing on key accomplishments, business value, and technical achievements. Delivered Relay Chain Block Processing Throughput Enhancement by enabling 12 blocks per relay parent with velocity tuning and new support constants, increasing relay chain throughput and scalability for parachain processing. No major bugs reported this month; changes prepared for rollout and code-reviewed to ensure operational readiness. Skills demonstrated include performance tuning, configuration management, and runtime-level development in a distributed network context.
