PROFILE
Lucas Åström
Worked on the eigerco/polka-storage repository over six months, delivering features and refactoring core components to improve maintainability, reliability, and deployment readiness. Focus areas included modernizing currency handling by migrating to Substrate’s Fungible traits, overhauling balance management, and enhancing benchmarking infrastructure for the storage provider and market pallets. Applied Rust and Substrate extensively, leveraging CI/CD pipelines and Nix for deterministic builds and deployment workflows. Addressed data integrity by fixing genesis balance duplication and streamlined code organization through modularization and trait-based design. The work established a robust foundation for scalable blockchain development and enabled more efficient, testable, and maintainable releases.

Jun 1, 2025June 2025 performance summary for eigerco/polka-storage: Delivered critical deployment and data integrity improvements with an emphasis on business value and long-term maintainability. Key features shipped include Paseo deployment readiness with deterministic runtime builds and chain spec generation, backed by Justfile targets for runtime building (srtool/Podman) and for chain spec creation, plus flake.nix updates to support deployment. Balance management was overhauled to rely on pallet_balances directly, removing custom BalanceTable and related no-ops, reducing code duplication and aligning with the runtime’s balance model. A genesis data fix addressed duplicate balances by adopting a unique data structure (BTreeMap) for endowed accounts and invulnerables, improving reliability of network bootstrapping. These changes collectively reduce deployment risk, improve data integrity, and establish a solid foundation for scalable balance management and future deployments.

May 1, 2025May 2025 monthly summary for eigerco/polka-storage. Focused on improving benchmarking reliability and realism for the storage provisioning stack. Delivered a unified benchmark data framework and testnet alignment across storage provider and market pallets. Core refactors centralized proving period offset logic in primitives, updated benchmarks to reflect runtime testnet constants, and reorganized benchmark data handling. Added PoSt benchmarking data and introduced a PoSt 1GiB sector benchmark scenario to improve realism and reliability of stress tests. These efforts establish a stronger baseline for performance baselining and enable faster iteration with more deterministic results.
