I am actually learning smart contract programming on ethereum and I work with truffle. Right now I am making this tutorial here: https://truffleframework.com/tutorials/building-dapps-for-quorum-private-enterprise-blockchains
Where you learn how to create a dapp with quorum. But now I have a problem.
I did everything exactly as described, but when I do:
truffle migrate
I get this error here:
$ truffle migrate
⚠️ Important ⚠️
If you're using an HDWalletProvider, it must be Web3 1.0 enabled or your migration will hang.

Truffle v5.0.1 (core: 5.0.1)
Node v8.11.4
Now I don't know why...
Does anyone have the same problem and can help me out here?
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;
}
}
And my truffle-config.js file:
module.exports = {
networks: {
development: {
host: "127.0.0.1",
port: 22000, // was 8545
network_id: "*", // Match any network id
gasPrice: 0,
gas: 4500000
},
nodefour: {
host: "127.0.0.1",
port: 22003,
network_id: "*", // Match any network id
gasPrice: 0,
gas: 4500000
},
nodeseven: {
host: "127.0.0.1",
port: 22006,
network_id: "*", // Match any network id
gasPrice: 0,
gas: 4500000
}
},
// Set default mocha options here, use special reporters etc.
mocha: {
// timeout: 100000
},
// Configure your compilers
compilers: {
solc: {
version: "0.4.25", // Fetch exact version from solc-bin (default: truffle's version)
}
}
}
And the migration file:
var SimpleStorage = artifacts.require("SimpleStorage");
module.exports = function(deployer) {
// Pass 42 to the contract as the first constructor parameter
deployer.deploy(SimpleStorage, 2, { privateFor: ["ROAZBWtSacxXQrOe3FGAqJDyJjFePR5ce4TSIzmJ0Bc="] })
};
So the problem was that the Block Timestamp was in Nanoseconds.
@edgraaff wrote a Proxy who converts the Timestamp from Nanoseconds to Seconds. You can find the code here -> https://github.com/edgraaff/quorum-rpc-proxy
What I had to do is to clone the proxy and change the config.js file to:
module.exports = {
rpcUrl: 'http://localhost:22000',
port: 7545
};
And in the truffle-config.js file i had to change the port. Here's the code:
module.exports = {
networks: {
development: {
host: "127.0.0.1",
port: 7545, // was 8545
network_id: "*", // Match any network id
gasPrice: 0,
gas: 4500000
},
nodefour: {
host: "127.0.0.1",
port: 22003,
network_id: "*", // Match any network id
gasPrice: 0,
gas: 4500000
},
nodeseven: {
host: "127.0.0.1",
port: 22006,
network_id: "*", // Match any network id
gasPrice: 0,
gas: 4500000
}
},
// Set default mocha options here, use special reporters etc.
mocha: {
// timeout: 100000
},
// Configure your compilers
compilers: {
solc: {
version: "0.4.25", // Fetch exact version from solc-bin (default: truffle's version)
}
}
}
Thanks to @edgraaff
