Jun 1, 2025

June 2025: Worldfnd/provekit — Delivered a comprehensive CI/CD infrastructure for Noir-R1CS benchmarks across ARM and Raspberry Pi 5. The work established a repeatable, scalable benchmarking pipeline with automated scheduling, improved artifact handling, and cross-architecture support. Key capability includes generation of a witness directly from a Prover.toml for Noir-R1CS programs, enabling end-to-end benchmarking from source to witness.

Apr 1, 2025

April 2025 monthly work summary focusing on key accomplishments across two repositories, emphasizing reliability, modern tooling, and deployment readiness. Delivered a Kurtosis devnet upgrade and ERC1967Proxy integration for worldcoin/world-chain, fixing contract deployment and end-to-end tests and updating scripts/config to reflect the new proxy approach. Improved CI workflow and code quality enforcement in worldfnd/provekit, including reordering checks for faster feedback, integrating rustfmt and Clippy, and tuning CI to avoid fail-fast and reduce noise. Stabilized the Rust toolchain and dependency management in provekit by enforcing nightly, pinning dependencies with rev hashes, and standardizing tooling configuration for reproducible builds. Overall, these changes reduce debugging time, accelerate review cycles, and increase reliability of deployments across both repos.

March 2025 monthly summary: Implemented backward-compatible compressed proofs support for PBHPayload validation in worldcoin/world-chain. Compressed proofs are decompressed before verification, enabling reduced bandwidth and storage while remaining compatible with older proof formats. This change improves verification throughput, reduces network costs, and preserves interoperability with legacy proof schemas across clients.
