March 2026 monthly summary focusing on key accomplishments in two repositories: hiero-improvement-proposals and hiero-consensus-node. Key features delivered include documentation alignment for system architecture references (Token Service -> Account Service) and protobuf changes enabling Crypto Account Delegation and EVM execution context under HIP-1340. No major bugs reported this month; work centered on feature delivery and architectural clarity in preparation for upcoming releases. Overall impact: improved architectural clarity and cross-service interoperability; enables delegated actions and EVM execution within account contexts, laying groundwork for streamlined workflows and improved security posture. Technologies/skills demonstrated: cross-repo HIP-1340 integration, Protobuf schema evolution, documentation updates, and code review/sign-off discipline.

January 2026 (2026-01) Monthly Summary for hiero-improvement-proposals Key features delivered: - EOA Code Delegation: Implemented the ability to set and update code delegation for externally owned accounts (EOAs) using Hiero-specific APIs and EVM transaction types. Introduced a Delegation Indicator for bytecode queries to improve compatibility and flexibility of smart contracts on the Hiero network. This work corresponds to HIP-1340 and is tracked in commit 6083cfe3015742d72c654e4a21c9495dfaf394b4. Major bugs fixed: - No major bugs fixed this month (no reported critical issues related to the features above). Overall impact and accomplishments: - Enables secure, flexible upgrade and delegation patterns for EOAs on the Hiero network, reducing deployment friction for dApps and improving interoperability of smart contracts. The HIP-1340 reference commit formalizes the change and demonstrates cross-team collaboration. Technologies/skills demonstrated: - EVM and Hiero-specific API integration - Bytecode query enhancements and Delegation Indicator design - Protocol design, feature flagging, and release readiness - Cross-functional collaboration and code sign-off across multiple engineers

Summary for 2025-10: The Hedera Services work focused on delivering the EVM module v0.67 with enhanced throttling and gas management, along with targeted bug fixes to improve error handling and synthetic action generation. The changes increased stability and predictability of smart contract execution, enabling better cost control and observability for operators and developers.

In September 2025, the Hedera Services project delivered deterministic operation duration throttling with nominal and brimful capacity management for contract execution. The work refactored throttling to use precise capacity accounting, updated configuration properties and tests to reflect the new logic, and enhanced resource usage control during contract execution. This delivers predictable operation timelines, improved throughput management, and stronger reliability for contract-heavy workloads, aligning with performance and operational goals.
