PROFILE
Mykhailo Lohachov
Over seven months, Andrey Lohachov contributed to the hyperledger-iroha/iroha repository by building and refining core backend and DevOps systems. He unified multiple CLI tools into a single Kagami binary, streamlined WASM build and deployment pipelines, and enhanced smart contract execution with dynamic fuel management. Using Rust, Python, and shell scripting, he improved CI/CD reliability, hardened dependency management, and introduced automated link checking for documentation. His work addressed network resilience, role management validation, and test flakiness, resulting in more predictable releases and maintainable code. Lohachov’s engineering demonstrated depth in asynchronous programming, system programming, and continuous integration for blockchain infrastructure.

May 1, 2025May 2025 monthly summary for hyperledger-iroha/iroha. Key accomplishments: 1) Delivered Dynamic Fuel Management for the WASM executor, enabling smart contracts to consume and add fuel and to query the current fuel level for improved execution control and observability. Commit: 588036272015b96400b04abd72a98652d55921c9. 2) Fixed Expired Transaction Events Handling: removed redundant expiration reporting after commits, refined the transaction removal logic to correctly handle expired and already-committed transactions, and added a regression test to validate behavior for expired transactions already present in the blockchain. Commit: 3ab964ce29370c5e9fb32fefc08b7b56e433c42d. Overall impact: more predictable WASM contract execution, correctness of transaction lifecycle, and enhanced regression coverage. Technologies/skills demonstrated: WASM runtime enhancement, Rust-based code changes, testing and regression verification, and maintainability.
