可以通过比特币钱包命令导出相关的交易记录,如果你想统计某个地址或者某个用户的交易时,可以解析该文件。
技术很简单,因为导出文件为JSON格式,这里通过alibaba的fastjson来解析。
首先,通过命令导出最近两条交易记录:
1 |
./cli listtransactions '*' 10 0 >>txid.txt
|
将导出的内容写入txid.txt文件,然后下载该文件
单条交易记录:

account,label保护隐私这里屏蔽
address交易的地址
category交易类型,receive为收,send为发
amount交易金额
confirmations区块链确认数
blockhash矿机计算出的hash
blockindex在钱包中的索引
blocktime时间
txid交易凭据
time交易时间
timereceived钱包接收时间
可以根据自己的需要进行解析、判断、统计,示例:

刚打出的币,确认数为0,节点确认后,确认数开始增加,-1代表失败。
