This repository uses the dapp.tools toolchain for interacting with Ethereum. Please install it first by running:
$ curl https://dapp.tools/install | sh
or check out https://dapp.tools/ for other installation options
If you want to run a local testnet with geth, the simplest way to do so is to run dapp testnet
$ dapp testnet
...
The following variables are required:
export ETH_PASSWORD=/dev/null
export ETH_GAS=5000000
export ETH_KEYSTORE=~/PATH_TO_KEYSTORE
export ETH_FROM=0x5a65c5e4289c34854f07dbb749ec7e8949a9131d
export ETH_RPC_URL=http://localhost:8545
Running ./setup-env will print the correct values for your local parity node or testnet instance.
For Rinkeby the the quickest setup is to use Infura.
If you run a local instance, you will need to deploy the centrifuge contracts, which is out of scope for this. Alternatively you can deploy an instance of AnchorMock from src/test/zknft.t.sol that will allow you to imitate the behavior of the contract as shown in the zknft.t.sol test file.
Make sure you export the registry address that is printed as the variable NFT_REGISTRY after the dployment is done.
The script test-transaction has a proof and the necessary data embedded to validate the circuit that is included in verifier.sol. You can execute it to see what it does.
This is an proof-of-concept prototype. This implementation is not ready for production use. It does not yet contain all the features, careful code review, tests and integration that are needed for a deployment. Future changes to the cryptographic protocol and data formats are likely.
