btcpool矿池-BlockMaker模块解析

核心机制总结

  • blkmaker可以连多个bitcoind节点
  • blkmaker监听和接收4类消息:RAWGBT、STRATUM_JOB、SOLVED_SHARE和NMC_SOLVED_SHARE
  • 监听RAWGBT目的为获取gbtHash/交易列表,用于构建Block,gbtHash和vtxs写入rawGbtMap_

* rawGbtMap_保存最近100条gbtHash/vtxs对

  • 监听STRATUM_JOB目的为获取jobId_/gbtHash,jobId_和gbtHash写入jobId2GbtHash_

* jobId2GbtHash_保存最近120条jobId_/gbtHash对

  • 监听SOLVED_SHARE目的为获取BlockHeader和coinbaseTx

* BlockHeader+coinbaseTx+vtxs构造Block

  • 构造好的Block会提交连接的所有bitcoind节点
  • 构造好的Block入库,入库字段包括:

* puid、worker_id、worker_full_name、job_id、height、hash
* rewards(即coinbaseValue)、size(即blksize)、prev_hash、bits、version、created_at
* created_at为入库时间非爆块时间

BlockMaker命令使用

BlockMaker用于监听kafka获取新的比特币区块和域名币区块,同时监听kafka获取Gbt消息和Job消息以构造交易列表,最后拼装完整区块提交给比特币节点。

blkmaker -c blkmaker.cfg -l log_dir
#-c指定blkmaker配置文件
#-l指定日志目录

blkmaker.cfg配置文件

//比特币节点
bitcoinds = (
{
rpc_addr = ""; //rpc地址
rpc_userpwd = ""; //rpc权限,格式如username:password
}
);
//kafka集群
kafka = {
brokers = "1.1.1.1:9092,2.2.2.2:9092,3.3.3.3:9092";
};
//mysql配置,用于存储已发现的块
pooldb = {
host = "";
port = 3306;
username = "dbusername";
password = "dbpassword";
dbname = "";
};
