Worked on the scroll-tech/ceno repository to redesign the Transcript system, introducing a trait-based architecture in Rust that enables flexible and forkable transcripts for zero-knowledge proof workflows. Developed the BasicTranscript struct and integrated bincode serialization to support compact statistics reporting, allowing end-to-end tests to display and validate ZKVM proof sizes and hash counts. Enhanced benchmarking and metrics collection to guide performance optimization and capacity planning. Addressed a critical integration test bug in the Godilock extension field by refining assertion handling in the from_base method, which improved test reliability and build stability. Focused on cryptography, integration testing, and API design.
