to generate inputs into ____.json, replace signature, msg, and ethAddress in node-ts scripts/generate_input.ts. currently, this file will only generate inputs for OpenAI JWTs and JWTs generated by our dummy JWT generator application(https://get-jwt.vercel.app/), but feel free to add more public keys to support JWTs from different sites.
on the last line of scripts/gen_inputs.ts, edit the json file name.
ts-node scripts/generate_input.ts
These circuits check for (1) valid rsa signature, (2) that the message is a JWT, (3) ownership of a specific email domain, and (4) JWT expiration.
compile circuits in root project directory.
./shell_scripts/1_compile.sh
generate witness
./shell_scripts/2_gen_wtns.sh
make sure to edit the input json file name to the correct input file you generated in the generate inputs step.

deploy blind and verifier contracts
npx hardhat run ./scripts/deploy.js --network goerli
in our code, we have examples of verifying an OpenAI JWT on-chain. however, ./contracts/Blind.sol is not updated with the current state of the circuit, since our proof of concept app, Nozee, does not use on-chain verification.
however, if you are interested in deploying on-chain, ./scripts/deploy.js allows you to do a hardhat deploy, and ./test/blind.test.js are examples of how we tested and deployed our previously working Blind.sol contract.
run hardhat contract tests, first create a secret.json file that has a private key and goerli node provider endpoint.
