What does it do?
Simply put, the zero-knowledge dapp is responsible to verify if a user belongs to a certain group, without revealing any more additional information (i.e. who the user is).
git clone https://github.com/kendricktan/hello-world-zk-dapp.git cd hello-world-zk-dapp npm install # Linux/Mac # Note: Only tested on node:12.14.1 # This starts up a ganache-cli process, # compiles the zk-snark circuits, # deploys the smart contracts # and finally generate some proofs to verify # if the user is part of the group or not npm run start # Docker docker build . -t zkdapp docker run zkdapp
