noname meets Ethereum: Integration with SnarkJS

We're excited to share that our programming language, noname, now supports R1CS, making it easier to write zero-knowledge (ZK) circuits and deploy them on Ethereum using SnarkJS. This update introduces an alternative to the common Circom language, with a simple and intuitive syntax inspired by Rust and Golang. In this post, we illustrate how to deploy a noname-based Sudoku circuit on Ethereum, demonstrating core benefits like proving a solution's correctness without revealing it. Dive in to explore how noname could potentially unify the fragmented zkSNARK ecosystem and simplify your circuit writing process!
