Question

I followed the tutorial of quorum with truffle: https://truffleframework.com/tutorials/building-dapps-for-quorum-private-enterprise-blockchains

Now I want to migrate the SimpleStorage.sol Smart Contract to the blockchain, but I want to make it to add the "PrivateFor" parameter.

This is my Smart Contract:

pragma solidity ^0.4.17;

contract SimpleStorage {
  uint public storedData;

  constructor(uint initVal) public {
    storedData = initVal;
  }

  function set(uint x) public {
    storedData = x;
  }

  function get() view public returns (uint retVal) {
    return storedData;
  }
}

This is my: 2_deploy_simplestorage.js

var SimpleStorage = artifacts.require("SimpleStorage");

module.exports = function(deployer) {
  deployer.deploy(SimpleStorage, 42, {privateFor: ["ROAZBWtSacxXQrOe3FGAqJDyJjFePR5ce4TSIzmJ0Bc="]})
};

But when I do truffle migrate, I get this error:

$ truffle migrate

If you're using an HDWalletProvider, it must be Web3 1.0 enabled or your migration will hang.

When I don't add the "privateFor" parameter, it works:

var SimpleStorage = artifacts.require("SimpleStorage");

module.exports = function(deployer) {
  deployer.deploy(SimpleStorage, 42)
};

But I need this privateFor parameter..

Does someone know how to fix this?

Hey @BlockChainProgrammer. Thanks for guiding me on how to use the Quorum proxy. It worked.

For this error, Try to upgrade/downgrade your truffle version to v4.1.

$ npm install -g truffle@4.1.10

and change the version of solidity to 0.4.24 in your truffle-config.js and the SimpleStorage.sol and add back privateFor in your migration file.

Thanks mate. I will check it out in a few hours – BlockchainProgrammer Jan 24 at 7:34
Hello, so you mean in SimpleStorage.sol this: pragma solidity ^4.1.24; and in the truffle-config.js file this: solc: { version: "4.1.24", } ? Because I get an error – BlockchainProgrammer Jan 24 at 7:45
That's right. In both of them you need the same version. It worked for me. – exploringsincebirth Jan 24 at 7:52
Also try to join this slack group, from the quorum website. – exploringsincebirth Jan 24 at 8:07
Hello, I get this error: SyntaxError: Source file requires different compiler version (current compiler is 0.4.24+commit.e67f0147.Emscripten.clang - note that nightly builds are considered to be strictly less than the released version pragma solidity ^4.1.24; – BlockchainProgrammer Jan 24 at 8:12

Problem solved!

What I had to do is to downgrade truffle to "4.1.10" with:

truffle uninstall -g

and then

npm install -g truffle@4.1.10
