PROFILE
Konrad Stepniak
Konrad developed core storage and proof-of-spacetime infrastructure for the eigerco/polka-storage repository, focusing on scalable, reliable blockchain-backed storage proofs. He engineered end-to-end PoRep and PoSt workflows, enabling on-chain verification, multi-partition support, and sector sizes up to 1GiB, while tuning parameters for mainnet readiness. Using Rust and Nix, he improved build reproducibility, introduced OpenCL/CUDA acceleration options, and streamlined configuration for cross-platform deployment. Konrad addressed testnet stability, optimized caching and concurrency, and enhanced P2P networking with public endpoint discovery. His work demonstrated depth in backend, cryptography, and distributed systems, delivering robust, maintainable features that improved throughput, reliability, and developer experience.

Mar 1, 2025March 2025 monthly work summary for eigerco/polka-storage: Focused on scalability and configurability enhancements for 1GiB sector proofs and governance of proof parameters. Implemented enabling of 1GiB sector proofs, hardened batch verification, updated verification key handling, and improved randomness procurement for batch verification. Refactored genesis configuration to include market and proofs pallet settings and introduced a download-params command to fetch proof parameters, simplifying testing and deployment. These changes reduce verification costs, improve security, and enhance parameter provisioning for large-scale deployments.

Jan 1, 2025January 2025 — eigerco/polka-storage: concise monthly delivery highlights focused on PoSt scalability, reliability, tooling, and robustness. Key features delivered: - PoSt scalability and reliability improvements: multi-partition PoSt support; generation and verification across partitions; improved storage-prover integration; performance throttling; support for 8MiB sector size. (Commits: verify multiple partitions in pallets; generate multiple proofs; throttle parallel prove commits; add 8MiB sector size; PoSt e2e test refactor.) Major bugs fixed: - ZeroPaddingReader: fixed incomplete reads to ensure correct padding and added test coverage for not-full reads. Tooling and dependency management updates: - Nix channel updates and bumps to polkadot and subxt-cli; flake tooling revisions to align with upstream changes. Overall impact and accomplishments: - Significantly improved PoSt scalability and reliability, enabling larger sector sizes and faster proof generation; better testing coverage and maintenance hygiene through tooling upgrades. Technologies/skills demonstrated: - Rust-based PoSt engineering, performance tuning (throttling), multi-partition proof logic, end-to-end PoSt testing, Nix/flakes tooling, dependency management, and robust test coverage.

Dec 1, 2024December 2024 monthly summary focused on reliability, throughput, and deployability for the eigerco/polka-storage stack. Delivered end-to-end PoSt capability with windowed-post submission, updated deadline handling for the next proving period, live sectors for proving partitions, and robust cancellation handling in the PoSt pipeline, enabling automated proof submission workflows. Improved storage performance through multi-cache directories per sector and cache-path usage in pre-commit and proving operations. Enhanced extrinsic submission reliability by parallelizing submissions with mutex-protected nonce management and robust finalization handling, paired with wait-for-success semantics. Fixed RPC timeout and transaction finalization issues during chain reorganizations by using finalized block hashes with a fixed validity window. Increased asynchronous block production stability with tuning of timestamp and parachain system settings and a polkadot-sdk upgrade. Documented OS support (Ubuntu 24.04) and deployment caveats to streamline onboarding. Overall, these changes boost throughput, reduce operational risk, and improve deployment readiness, aligning technical work with business value by enabling faster, safer proofs, more reliable transactions, and easier deployment."
