祝学习愉快。 Happy Learning. All the demo can be found in bilibiliDemo folder. 所有的视频示例都可以在 bilibiliDemo文件夹里找到
npm install --save
yarn
如果作为依赖安装, it's published to npm, so if you want to install it as an dependency, please use
npm install --save luotuocoin
or
yarn add luotuocoin
npm run test or yarn test
密钥对讲用于发起转账,公钥(public key)会用作你的钱包地址,私钥(private key)会用来生成转账的数字签名。 The keypair will be used for signing transactions(private key) and receving miner rewards/transactions, public key will be your wallet address.
const ecLib = require("elliptic").ec;
const ec = new ecLib("secp256k1"); // curve name
const sha256 = require("crypto-js/sha256");
// 生成我们的密钥对 generate the keypair
const key = ec.genKeyPair();
// 拿到我们的私钥和公钥 希望拿到hex string格式的
console.log("private", key.getPrivate("hex"));
console.log("public", key.getPublic("hex"));
const { chain, transaction } = require("luotuocoin"); const myCoin = new chain();
利用上述步骤生成的keypair object, use the keypair object generated above
// 发起一笔转给to 10块钱的交易
// create a transaction that transfer 10 coin to address 'to'
const transaction = new Transaction(key.getPublic("hex"), "to", 10);
transaction.sign(key);
myCoin.addTransaction(transaction);
同样需要利用之前生成的 key object,将公钥作为参数传入挖矿的方法,如果你最后挖矿成功,区块链会向这个地址发放一个矿工奖励。 Using the same keypair object, passin the public key to receive the minder reward.
myCoin.mineTransactionPool(key.getPublic("hex"));
