PROFILE
Pawel Polewicz
During a three-month period, Piotr Polewicz enhanced the opentensor/subtensor repository by delivering governance-driven features and improving code quality. He implemented runtime-configurable parameters such as StartCallDelay, enabling dynamic control of network behavior without redeployment. Using Rust and TypeScript, Piotr refactored storage declarations and introduced EMA-based voting power governance, focusing on type safety and deterministic benchmarks. His work included comprehensive testing, migration of configuration to storage, and improvements to localnet tooling with bash scripting. By addressing initialization safety, permission checks, and code maintainability, Piotr demonstrated depth in blockchain development and contributed to the reliability and future scalability of the project.

Jan 1, 2026January 2026 (opentensor/subtensor) delivered substantive improvements across genesis configuration, governance, and code quality, with clear business value in benchmarks, reliability, and maintainability. Key work includes: (1) Start Call Delay: added as an optional GenesisConfig field, removed the redundant getter, and used the config constant directly in storage to simplify access and enable deterministic benchmarks. Commits: 0cb4b8830e89849c5bd89d9f7e887eca0ed548ca; 0bd25dfa4a371372f8baa3219c70c197a42b58bb; bb6495b820d5d266e031a7366965cdfd2f6bb6c6. (2) Voting Power EMA governance: introduced and refined EMA-based governance with alpha adjustments, address/precompile updates, and tests; migrated stake type to AlphaCurrency for type safety. Commits include 834f14cefa209f8a611bc06b58a748ebde2c4158; 61968495f4dd9569bf2080eba7a0061658f8b5b9; 9b43431ba7eae29afdfcfdbbf1e2f98ceecb706d; d5d985f2d61745243585c31cb0294befe1892dd7; 0e1bd21ea9b82319a75d87d2c0943a818dce2dcf; 1526f896e872eb6b6b8483669df084c003146816; c66f7823d91e456798bc249fe59244141e423982. (3) Code quality and test improvements: refactoring, formatting, and lint fixes to improve maintainability and CI reliability.

Dec 1, 2025December 2025 summary for opentensor/subtensor: Enabled governance-driven runtime configurability for StartCallDelay by replacing the hardcoded delay with a storage-backed hyperparameter (InitialStartCallDelay) controlled via sudo_set_start_call_delay. Implemented storage accessors (get_start_call_delay/set_start_call_delay), migration to storage-based config, and genesis initialization. Added end-to-end tests validating permission checks and immediate effect when the delay is reduced to zero, ensuring subnet start-up can be controlled at runtime without upgrades. Localnet was configured to initialize StartCallDelay to 10 blocks to accelerate testing. Also enhanced localnet patch tooling (patch_file function) and applied code quality improvements (cargo fmt) across admin-utils and subtensor pallets. Updated tests and contract references to reflect the new constant and API names for consistency and maintainability.
