Roshan Rags delivered a major upgrade to the RISC0 verifier within the marlinprotocol/oyster-monorepo, focusing on improving reliability and developer productivity. He updated the risc0 and risc0-zkvm dependencies across both host and guest components, ensuring compatibility with the latest releases. By removing Docker-specific build steps and introducing environment-variable-driven builds, Roshan streamlined the build process and made reproducible builds more accessible. He revised the documentation in Markdown to clarify CUDA disablement and reproducible build options, and updated the expected GUEST_ID. His work demonstrated depth in Rust, build systems, and dependency management, addressing maintainability and workflow efficiency for the team.

September 2025: Delivered a major upgrade of the RISC0 verifier across the oyster-monorepo and streamlined the build process for reproducible builds. Key changes include upgrading the risc0 version and dependencies (host/guest, risc0-zkvm) to align with the latest release, and removing Docker-specific build instructions in verifier-risczero in favor of environment-variable-driven builds. Updated README to explain how to disable CUDA during builds, enable reproducible builds via Docker when needed, and reflect updated GUEST_ID. No critical bugs fixed this month; primary focus was on reliability, compatibility, and developer productivity.
