As a result, it currently unrolls all assembly codes, making it susceptible to exceeding the contract size limit, even with a moderately sized circuit. +- The existing solution involves complex abstractions and APIs for consumers. -So this repo is rebuilt from scratch, with focus also on codesize and readability, and surprisingly the gas cost is similar (even a little bit less) compared to the one generated by `snark-verifier` +This repository is a ground-up rebuild, addressing these concerns while maintaining a focus on code size and readability. Remarkably, the gas cost is comparable, if not slightly lower, than the one generated by `snark-verifier`. ## Acknowledgement
