Dapp: setup and run

Setup and run the dapp

With the verification keys generated, you need to configure your local Chromia node to use them.

The generated verification keys must be configured in rell/chromia.yml. The contents of the .json files generated in the previous step must be added into this chromia.yml file manually.

rell/chromia.yml

gtx:
  modules:
    - "net.postchain.zkp.ZKPGTXModule"

zkp:
  plonk:
    verification_keys:
      shield_operation:
        # Copy contents from shield_operation_verification_key.json
      unshield_operation:
        # Copy contents from unshield_operation_verification_key.json  
      private_transfer:
        # Copy contents from verification_key.json

The already generated keys can be used from the example repository.

Next, run a local directory node using Docker:

docker run --rm -it -p 7740:7740/tcp registry.gitlab.com/chromaway/example-projects/directory1-example/managed-single:0.7.1

cd rell

Generate a provider keypair:

chr keygen -f provider-keypair

And deploy the dapp to your local network:

chr deployment create -y -d local --secret provider-keypair

Expected output:

deployments:
  local:
    chains:
      zkp_demo: x"3E339D3D2AB109....EC3CD97681134"
