PROFILE

武宮誠

Takemiya contributed to the sora-xor/sora2-network and hyperledger-iroha/iroha repositories, focusing on blockchain infrastructure and SDK enhancements. Over three months, he delivered a feature-rich Eth-bridge upgrade that improved fee control and network reliability, using Rust and Substrate to implement mechanisms for predictable fee application and congestion prevention. He also released a Wasm upgrade aligned with updated chain specifications, enhancing performance and observability through targeted code substitutions and improved test instrumentation. For hyperledger-iroha/iroha, Takemiya performed comprehensive SDK and architectural improvements in Rust and Swift, reducing technical debt and preparing the codebase for future features and more stable releases.

October 2025 summary for sora-xor/sora2-network: Delivered a feature-rich upgrade to Eth-bridge operations, improving fee control, reliability, and maintainability. Key outcomes include a mechanism to reset the fee multiplier at a specific block height for predictable fee application; an operational runbook for clearing stalled outgoing requests in the eth-bridge pallet; a new request queue limit to prevent network congestion; and refined CI configuration with dependency updates. Telemetry was bumped to reflect the new fee control behavior. No major defects were reported this month; the focus was on delivering this feature and improving CI/observability. Overall impact: improved economics predictability, reduced risk of congestion and stalled requests, and faster, safer deployments. Technologies/skills demonstrated: Substrate pallet development, on-chain governance considerations for fee logic, CI/CD optimization, observability/instrumentation, and operational automation.
