学不动了，好多都听不懂，而且对端口网络连接的一点办法都没有，乱撞，以太坊学习就到这吧，有了基础再深入学习

?同步回调：会阻塞进程，有顺序保证
?异步回调，序列化：一般web应用都是用异步调用
编译过程：编译sol文件
?--bin生成字节码文件，给以太坊去执行
?--abi生成abi文件，供web3去调用
?node控制台：js的执行环境，编写好的js文件，可以用node直接去运行
?创建一个web3对象（web3是一个名字，随意）
?BigNumber
?s：表示一个符号，表示正负号。整数是1，负数是-1
?e：科学计数法的位数
?c：是一个数组，每14位切割一次，从低位开始切割
web3中：ctrl+L是一键清屏
