July 2026 monthly work summary for the Neo projects. Delivered key network upgrade capability and safety improvements across two repositories, plus CI tooling upgrades. Highlights include HF_Huyao support and Notary Deposit safety enhancements in neo, and CI tooling upgrade in neofs-node, with tests and improved stability.

June 2026: Delivered key RC V2 refactor and Neo VM upgrade for the Neo Smart Contract Framework, focused on maintainability, compatibility, and runtime efficiency. The work aligns external reference counting with RC V2 across core stack and serialization paths, reducing embedded state and simplifying stack operations, while preparing for future RC V2 enhancements. Upgraded Neo.VM to 3.10.1-CI00378 to leverage latest fixes and features, ensuring better VM correctness and performance. Included test cleanup and CI/build alignment to reflect RC V2 changes, with preserved interoperability behavior for SmartContract event args. Result: stronger code hygiene, safer reference management, and a smoother upgrade path for RC V2 adoption across the runtime and tooling.

April 2026 monthly summary for neo-project/neo. Focused on hardfork safety and correctness for the Neo VM and on precise activation gating for native methods/events. Implemented safer SHL/SHR handling in SmartContract and moved the fix to the Gorgon hardfork, reducing the risk of state divergence during fork transitions. Reworked activation logic so native methods/events activate only when ActiveIn is active and DeprecatedIn is not active. Added unit tests to validate hardfork-related safety and activation behavior, improving test coverage and release confidence. These changes collectively reduce upgrade risk, improve security, and strengthen core reliability for production deployments.

Concise monthly summary for 2026-03 focusing on key features delivered, major bugs fixed, overall impact, and technologies demonstrated across neo-project/neo and nspcc-dev/neofs-node. Emphasizes business value, reliability improvements, and execution efficiency.

February 2026 monthly summary for nspcc-dev/neofs-node: Focused on reliability and developer velocity through notary event parsing improvements, AppCall parsing modernization using NeoGo scparser, and broad codebase maintenance. Demonstrated Go expertise, improved error handling, and streamlined tooling to reduce bugs and accelerate future changes. Key outcomes include cleaner parsing workflows, clearer errors, and upgraded dependencies and build tooling.

January 2026 monthly summary for the neo-project/neo repository. Delivered policy-driven contract enhancements and a critical build fix, improving contract reliability, fund recovery capabilities, and deployment stability.

December 2025 monthly summary for neo-project/neo focused on governance upgrade readiness and NEP-30 standardization across native contracts. Delivered hardfork-aware governance enhancements by updating PolicyContract callflags to align with NEO.VoteInternal changes and Faun hardfork behavior switch. Introduced NEP-30 support across native Treasury, Notary, and Oracle contracts with configurable active hardforks to enable contract updates without disrupting existing functionality, improving upgradeability and ecosystem robustness.

Summary for 2025-05: Delivered a strategic code refactor across neo's native contracts to unify hardfork enablement checks, reducing fork risk and improving maintainability. The change centralizes hardfork logic via ApplicationEngine.IsHardforkEnabled, removing redundant block index retrieval and ensuring backward-compatible behavior. While this month focused on consolidation and risk reduction, it lays the foundation for simpler future enhancements and consistent behavior across native contracts.

Month: 2025-04 — The Neo project delivered core policy and consensus improvements, reinforcing reliability, security, and business value. Initiatives focused on migrating critical timing and policy settings to the native Policy contract, enabling precise governance of block timing, fee attributes, and hardfork alignment; introducing native Notary capabilities for Notary-Assisted transactions; refining consensus timing for accurate block interval validation; and updating testnet configuration to ensure current NeoFS settings in the CLI.

March 2025 monthly summary for neo-project/neo focusing on value delivered, reliability, and developer experience. Highlights include the introduction of Notary Assisted Transaction Attribute with verification logic and integration into network fee calculation, along with a stub for the notary contract hash to enable future notary contract deployments. A SmartContract Notification Rate Limiting mechanism was added to cap notifications per application execution (MaxNotificationCount) and is enforced after the HF_Echidna hardfork to protect performance under load. A CryptoLib Ed25519 naming consistency refactor unified argument naming with verifyWithECDsa, improving manifest readability and cross-module consistency. These changes establish groundwork for compliant notary workflows, stabilize performance, and enhance developer experience.

Month: 2024-12 – Focused on stabilizing core networking paths and reducing technical debt across two critical repositories. Key outcomes include SDK initialization cleanup in neofs-node and P2P capability enhancements in neo, delivering tangible business value through improved reliability, interoperability, and future-proofing for unknown capabilities.

In Oct 2024, focused on strengthening the reliability of the MODPOW opcode in neo-project/neo by extending edge-case test coverage to align with NeoGo VM behavior, reducing risk of regressions and improving cross-VM compatibility. The work reinforces core arithmetic correctness in the VM and supports future feature work with robust tests.
