# btcpool礦池-BlockMaker模組解析

## 核心機制總結

* blkmaker可以連多個bitcoind節點
* blkmaker監聽和接收4類訊息：RAWGBT、STRATUM_JOB、SOLVED_SHARE和NMC_SOLVED_SHARE
* 監聽RAWGBT目的為獲取gbtHash/交易列表，用於構建Block，gbtHash和vtxs寫入rawGbtMap_
  * rawGbtMap_儲存最近100條gbtHash/vtxs對
* 監聽STRATUM_JOB目的為獲取jobId_/gbtHash，jobId_和gbtHash寫入jobId2GbtHash_
  * jobId2GbtHash_儲存最近120條jobId_/gbtHash對
* 監聽SOLVED_SHARE目的為獲取BlockHeader和coinbaseTx
  * BlockHeader+coinbaseTx+vtxs構造Block
* 構造好的Block會提交連線的所有bitcoind節點
* 構造好的Block入庫，入庫欄位包括：
  * puid、worker_id、worker_full_name、job_id、height、hash
  * rewards（即coinbaseValue）、size（即blksize）、prev_hash、bits、version、created_at
  * created_at為入庫時間非爆塊時間

## BlockMaker命令使用

BlockMaker用於監聽kafka獲取新的比特幣區塊和域名幣區塊，同時監聽kafka獲取Gbt訊息和Job訊息以構造交易列表，最後拼裝完整區塊提交給比特幣節點。

```shell
blkmaker -c blkmaker.cfg -l log_dir
#-c指定blkmaker配置檔案
#-l指定日誌目錄
```

## blkmaker.cfg配置檔案

```shell
//比特幣節點
bitcoinds = (
{
rpc_addr = ""; //rpc地址
rpc_userpwd = ""; //rpc許可權，格式如username:password
}
);

//kafka叢集
kafka = {
brokers = "1.1.1.1:9092,2.2.2.2:9092,3.3.3.3:9092";
};

//mysql配置，用於儲存已發現的塊
pooldb = {
host = "";
port = 3306;
username = "dbusername";
password = "dbpassword";
dbname = "";
};
```
