Quorum Ethereum Truffle) Error: Number can only safely store up to 53 bits
Quorum Ethereum Truffle) Error: Number can only safely store up to 53 bits
我实际上正在学习以太坊上的智能合约编程，并且我使用 truffle。现在我正在这里制作这个教程：https://truffleframework.com/tutorials/building-dapps-for-quorum-private-enterprise-blockchains
您可以在其中学习如何创建具有 quorum 的 dapp。但是现在我有一个问题。
我完全按照描述做了所有事情，但是当我这样做时：
truffle migrate
我在这里遇到这个错误：
$ 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
现在我不知道为什么...
有没有人遇到同样的问题可以帮我解决这个问题？
这是我的智能合约：
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;
}
}
还有我的松露-config.js 文件：
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)
}
}
}
以及迁移文件：
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="] })
};
所以问题是块时间戳以纳秒为单位。
@edgraaff 写了一个 Proxy 将时间戳从纳秒转换为秒。
您可以在此处找到代码 -> https://github.com/edgraaff/quorum-rpc-proxy
我必须做的是克隆代理并将 config.js 文件更改为：
module.exports = {
rpcUrl: 'http://localhost:22000',
port: 7545
};
并且在 truffle-config.js 文件中我不得不更改端口。这是代码：
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)
}
}
}
感谢@edgraaff
@QuorumPrivateBlockChain 嗨伙计。
所以这是我的松露-config.js 文件：
module.exports = {
networks: {
development: {
host: "127.0.0.1",
port: 7545,
network_id: "*",
gasPrice: 0,
gas: 4500000
},
nodefour: {
host: "127.0.0.1",
port: 7546,
network_id: "*",
gasPrice: 0,
gas: 4500000
},
nodeseven: {
host: "127.0.0.1",
port: 7547,
network_id: "*",
gasPrice: 0,
gas: 4500000
}
},
compilers: {
solc: {
version: "0.4.25",
}
}
}
这是我来自代理的 config.js 文件：
module.exports = [
{
rpcUrl: 'http://localhost:22000',
port: 7545
},
{
rpcUrl: 'http://localhost:22003',
port: 7546
},
{
rpcUrl: 'http://localhost:22006',
port: 7547
},
];
所以你要做的是，将请求从 truffle 发送到代理，然后代理转换时间戳并将请求进一步发送到节点。
代理本身就是一个程序，您不必从代理代码中复制 config.js 文件。查看 github 如何启动代理。
代理不够用，因为web3.js可以通过ws
获取block in subscribtion
此外，在 quorum 中，按数字获取块已被破坏，它只接受十六进制，但是 web3.js 将十六进制假设为 blockhash
这是我的解决方案
web3.extend({
property: 'eth',
methods: [new web3.extend.Method({
name: 'getBlockByNumber',
call: 'eth_getBlockByNumber',
params: 2,
inputFormatter: [web3.extend.formatters.inputBlockNumberFormatter, v => !!v],
outputFormatter: web3.extend.formatters.outputBlockFormatter
})]
});
web3.utils.hexToNumber = v => {
if (!v) return v;
try {
return numberToBN(v).toNumber();
} catch (e) {
return numberToBN(v).toString();
}
};
注意时间戳现在是字符串
这是 web3.js 回购 https://github.com/ethereum/web3.js/issues/1215
中的相关问题
如果您将 truffle 版本降级到 4.1.15，则无需使用任何代理。如果您这样做，一切都会正常进行。只是不要降级到 4.1.14，因为 truffle init 在那个包里坏了！
简单修复：只需在您的 truffle-config 中添加 type: "quorum"，因为网络应该 运行 法定人数。
目前（2020 年 5 月），基本上您有两种解决方法：
- 在
truffle-config.js或networks.js中添加type: "quorum"，例如：
myLocalQuorum: {
protocol: 'http',
host: 'localhost',
port: 22000,
gas: 5000000,
gasPrice: 0,
networkId: '*',
type: "quorum"
},
- 如果您正在使用
@truffle/hd-wallet-provider，没有简单的解决方法，但您可以将共识切换为 istanbul 而不是 raft，请参阅 oz community更多详情。
When running the default consensus Istanbul BFT, I can deploy and interact with a contract using Truffle and OpenZeppelin SDK.
When I switch to RAFT I wasn’t able to deploy a contract using truffle migrate nor oz create. I didn’t see anything different I needed to do config wise in the Truffle documentation for RAFT. by @abcoathup
