充值处理逻辑文档

对充值操作节点有以下要求：

• 本地区块数据与主网保持同步

通过查看P2P网络上主节点的高度，对比本节点当前区块高度，确保在充值前保持区块与主网的同步：
bigbang> getforkheight
10385

bigbang> listpeer
[
    {
        "address" : "18.182.192.156:9901",
        "services" : "0000000000000003",
        "lastsend" : 1573026263,
        "lastrecv" : 1573026263,
        "conntime" : 1573023035,
        "pingtime" : 238,
        "version" : "0.1.0",
        "subver" : "/Bigbang:0.9.2/Protocol:0.1.0/a94044fce7f1a123f7e9c43633417cb2397e9805:r",
        "inbound" : false,
        "height" : 10385,
        "banscore" : 100
    },
    {
        "address" : "18.138.93.175:9901",
        "services" : "0000000000000003",
        "lastsend" : 1573026262,
        "lastrecv" : 1573026263,
        "conntime" : 1573019633,
        "pingtime" : 432,
        "version" : "0.1.0",
        "subver" : "/Bigbang:0.9.2/Protocol:0.1.0/a94044fce7f1a123f7e9c43633417cb2397e9805:r",
        "inbound" : false,
        "height" : 10383,
        "banscore" : 100
    }
]

• 确保本地节点上的钱包余额足够支付给对方

确保支付地址的锁定和未确认金额部分为0，有效余额部分大小接收金额加交易费用：
bigbang> getbalance
[
    {
        "address" : "181x15vfy56wrhaxqspz8mgaex618t6zk7fchemyaxt7qx5txggt9hprc",
        "avail" : 50.260000,
        "locked" : 0.000000,
        "unconfirmed" : 0.000000
    },
    {
        "address" : "1f9vq3gwbrzw0sb7e8fvy2raqfrc8zvnw8esy7rgk41t9d0zmy78bj48e",
        "avail" : 934999079.772600,
        "locked" : 0.000000,
        "unconfirmed" : 4999970.117400
    },
    {
        "address" : "1965p604xzdrffvg90ax9bk0q3xyqn5zz2vc9zpbe3wdswzazj7d144mm",
        "avail" : 739999957.250000,
        "locked" : 0.000000,
        "unconfirmed" : 0.000000
    }
]

• 确保密钥的密码正确和安全

可以随时修改密钥的密码，下面执行的例子表示将密钥从以前的旧密码123改成新密码321：
bigbang> encryptkey 34845d977e8feeca5317d93bf31b8d82e94e418abecdb7ab88b929feed127a40 -old=123 -new=321
Encrypt key successfully: 34845d977e8feeca5317d93bf31b8d82e94e418abecdb7ab88b929feed127a40

并及时锁定密钥：
bigbang> lockkey "da915f7d9e1b1f6ed99fd816ff977a7d1f17cc95ba0209eef770fb9d00638b49"
Lock key successfully: da915f7d9e1b1f6ed99fd816ff977a7d1f17cc95ba0209eef770fb9d00638b49

使用RPC命令gettransaction查看交易的确认数，3个确认即可保证主链历史数据不可回滚，以下交易的确认数为5004，我们认为这笔交易是有效的不可更改的：

bigbang> gettransaction "5daac19e2c83c782744980b2f01a49cc657b2d61bfdace3be08eb213f43cf899"
{
