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。

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);
