内容摘要

这一部关于区块链开发及运维的电子书。

为什么会写区块链电子书？因为2018年是区块链年，区块链是一个风口，前几个风口我都错过了。例如web2.0, 云，大数据等等，都从身旁擦肩而过。所以我要抓住这次。

这本电子书是否会出版（纸质图书）？不会，因为互联网技术更迭太快，纸质书籍的内容无法实时更新，一本书动辄百元，很快就成为垃圾，你会发现目前市面的上区块链书籍至少是一年前写的，内容已经过时，很多例子无法正确运行。所以我不会出版，电子书的内容会追逐技术发展，及时跟进软件版本的升级，做到内容最新，至少是主流。

这本电子书与其他区块链书籍有什么不同？市面上大部分区块链书籍都是用2/3去讲区块链原理，只要不到 1/3 的干货，干货不够理论来凑，通篇将理论或是大谈特谈区块链行业，这些内容更多是头脑风暴，展望区块链，均无法落地实施。本书与那些书籍完全不同，不讲理论和原理，面向应用落地，注重例子，均是干货。

写作原则，无法落地的项目作者绝对不会写。凡是写入电子的内容均具备可操作，可落地。

电子书更新频率？每天都会有新内容加入，更新频率最迟不会超过一周，更新内容请关注 https://github.com/netkiller/netkiller.github.io/commits/master

本文采用碎片化写作，原文会不定期更新，请尽量阅读原文。

配置 truffle.js

[ethereum@netkiller truffle]$ cat truffle.js
module.exports = {

8.3.4.2. 控制台检查合约

var contract;
NetkillerAdvancedTokenAirDrop.deployed().then(function(instance){contract=instance;});
contract.symbol.call().then(console.log);
contract.name.call().then(console.log);
contract.totalSupply.call().then(console.log);
contract.balanceOf.call(web3.eth.accounts[0]).then(console.log);

8.3.4.3. 测试转账

contract.transfer(web3.eth.accounts[1],100).then(function(){contract.balanceOf.call(web3.eth.accounts[1]).then(console.log);});

contract.transferFrom(web3.eth.accounts[0],web3.eth.accounts[1],100).then(function(){contract.balanceOf.call(web3.eth.accounts[1]).then(console.log);});

8.3.4.4. 锁仓

contract.setLock(true);
contract.transfer(web3.eth.accounts[2],100).then(function(){contract.balanceOf.call(web3.eth.accounts[2]).then(console.log);});

演示

truffle(development)> contract.setLock(true);
{ tx: '0x6a603ca9456b574224aa97b8bf1d66280fc8509c94253c0037bc5bb71135a667',

解锁后再测试

contract.setLock(false);
contract.transfer(web3.eth.accounts[2],100).then(function(){contract.balanceOf.call(web3.eth.accounts[2]).then(console.log);});

truffle(development)> contract.setLock(false);

undefined
truffle(development)> BigNumber { s: 1, e: 2, c: [ 100 ] }

8.3.4.5. 测试空投

[ethereum@netkiller ~]$ geth account new

contract.mintAirdropToken(1000000);
contract.totalAirdropSupply.call().then(console.log);
contract.totalSupply.call().then(console.log);
contract.setAirdrop(10);
contract.setAirdropLock(true);
