-We are going to describe them in the next part of this article. Alice is going to use two external tools [Cricom](https://docs.circom.io/getting-started/installation/) and [SnarkJS](https://github.com/iden3/snarkjs). Circom is a compiler written in Rust for creating circuits. SnarkJS is a npm package, which implements generation and validation of the zk-SNAKRs for the artifacts produced by Circom. For the installation process, please check our [documentation](https://github.com/bright/zk-snarks-with-substrate/blob/main/circom/README.md) in the repository.
