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 = "";
};
