Download a Powers of Tau file with 2^21 constraints and copy it into the
circuits subdirectory of the project, with the name pot21_final.ptau. We do not provide such a file in this repo due to its large size. You can download and copy Powers of Tau files from the Hermez trusted setup from this repository.
Follow the scripts in /scripts in order to generate chunked zkeys for this circuit. You will need a machine with large RAM and SWAP to perform these operations, we used a r5.4xlarge AWS machine to generate everything.
