Worked on the availproject/avail repository to deliver Polynomial Multiproof integration, focusing on enhancing data availability and proof verification efficiency. Leveraged Rust and cryptography expertise to refactor block-length and data-availability ratio logic, improving both performance and maintainability. Introduced new RPC methods that enable faster querying and verification of multiproofs, directly supporting scalable proof workflows for clients. Updated dependencies to ensure compatibility and stability within the codebase. The work addressed core blockchain challenges around data availability and zero-knowledge proofs, laying a technical foundation for future scalability. No bugs were fixed during this period, with efforts concentrated on feature development and architectural improvements.
