区块链开发之确定性算法bip32，bip39，bip44
##引言
随着比特币区块链的发展，人们已经不满足于，只有一个账号的情况，有些人会有好几个账户，但是这就出现一个问题，我有几个账号，就要保存几个私钥，这就特别麻烦和不友好，所以，就出现了bip32确定性算法，该算法可以让你只有同一个种子，就可以生成无数个私钥和地址，这就大大方便了用户的使用。但是这个种子，也不较长，用户使用起来也比较繁琐，这就出现了bip39，它是使用助记词的方式，生成种子的，这样用户只需要记住，12个单词（3,6,9,12，15,18,21，24支持这些单词数，目前使用较广泛的是12和24），这就有大大提高了用户使用的便利性。又随着区块链发展，市面上出现了很多币种，之前的确定性算法只是针对比特币的，也就是说只支持一种币种，用户想用同一个种子，管理不同币种，这就促使了bip39协议的出现，它是基于bip32协议的，它给bip32的路径，赋予了不同的意义，很好的解决了多币种，多地址的问题。

如果想详细的了解这些协议，请查看官方文档（解析的最清楚）

bip44：https://github.com/bitcoin/bips/blob/master/bip-0044.mediawiki

#BIP44简介
##路径级别
bip44给bip32定义了5各级别
m / purpose’ / coin_type’ / account’ / change / address_index
##m是固定的
Purpose也是固定的，值为44（或者 0x8000002C）
##Coin type
这个代表的是币种，0代表比特币，1代表比特币测试链，60代表以太坊
完整的币种列表地址：https://github.com/satoshilabs/slips/blob/master/slip-0044.md
##Account
代表这个币的账户索引，从0开始
##Change
常量0用于外部链，常量1用于内部链（也称为更改地址）。外部链用于在钱包外可见的地址（例如，用于接收付款）。内部链用于在钱包外部不可见的地址，用于返回交易变更。 (所以一般使用0)
##address_index
这就是地址索引，从0开始，代表生成第几个地址，并且官方建议，每个account下的address_index不要超过20
###示例
| coin account | change | address | path |
|---|---|---|---|
| Bitcoin | first | external | first |
| Bitcoin | first | external | second |
| Bitcoin | first | internal | second |
| Bitcoin | Testnet | first | external |
| Bitcoin | Testnet | second | external |
