Erhan Yildirim refactored the Circom adapter in the lambdaclass/lambdaworks repository to support Groth16 over the BLS12-381 curve, enabling seamless reading of R1CS and witness files and converting them into a QAP format compatible with Lambdaworks. He streamlined the codebase by removing the Metal feature, reducing dependencies and simplifying the build process. Working primarily in Rust and JavaScript, Erhan updated documentation and addressed lint and Clippy issues to improve maintainability and CI reliability. His work demonstrated a strong grasp of cryptography, zero-knowledge proofs, and code refactoring, delivering a focused and technically deep feature within the project’s scope.
