阅读bitcoin白皮书bitcoin-paper （bitcoin-paper(中文版)），学习区块链知识，用JavaScript简单实现了区块链的一些概念(Some concepts of blockchain are simply implemented in JavaScript to learn blockchain knowledge)

功能(Features)

  • 区块链的验证(JavaScript implementation of blockchain to prevent data from being tampered with)
  • 工作量证明机制的简单实现(Simple implementation of proof-of-work mechanism)
  • 转账(Transaction)
  • 挖矿的简单实现(Mine)
  • 生成密钥对(Generate keyPair)

开始(Get Started)

生成密钥对

const ecLib = require("elliptic").ec;
const ec = new ecLib("secp256k1"); // curve name
const sha256 = require("crypto-js/sha256");
// 生成密钥对 
const keyPair = ec.genKeyPair();
// 拿到 hex string 格式的私钥和公钥
console.log("privateKey", keyPair.getPrivate("hex"));
console.log("publicKey", keyPair.getPublic("hex"));

创建区块链(Create Blockchain)

const myCoin = new chain();

转账(Transaction)

const transaction = new Transaction("addrSender1", "addrReceiver1", 10);
myCoin.addTransaction(transaction);

挖矿(Mine)

myCoin.mineTransactionPool('addr3');

待完善(TODO)

  • 交易签名(Sign transactions.)
