Michael Bradley, Jr 1225cb14e8 build(deps): add core-js@3 as a dep to all pkgs that have @babel/runtime-corejs3 dep When making use of the `useBuiltIns: 'usage'` option for @babel/preset-env (which is the case for all transpiled packages in Embark's monorepo) a package needs to have both @babel/runtime-corejs3 and core-js@3 specified as dependencies.		2019-10-28 11:40:48 -05:00

`embark-snark`

Snark plugin for Embark

Compiles circom circuits and generate solidity proofs in an Embark DApp.

Installation

In your embark dapp directory:

npm install embark-snark --save

Then add embark-snark to the plugins section in embark.json:

"plugins": {
  "embark-snark": {
    "circuits": ["app/circuits/**"],
    "inputs": {
      "multiplier": {
        "a": 3,
        "b": 11
      }
    }
  }
}

You can defined where your circuits will be and what are the inputs.

Now you can create your first circuits, for example, app/circuits/multiplier.circom:

template Multiplier() {
  signal private input a;
  signal private input b;
  signal output c; c <== a*b;
}

component main = Multiplier();

Embark will now compile the circuits and generate a solidity contracts to verify the proof as well as deploy it.

Requirements

Embark 5.0.0-alpha.0 or later
