eth_getWork extension fields for BTCPool的疑问 #376

Closed rocqina closed 5 years ago

rocqina commented 5 years ago

原生的eth_getWork没有那么多返回值，这个是btcpool自己修改了全节点有更多返回数据的版本吧。这个和原生eth_getWork的区别是什么，毕竟原生的处理逻辑通过别的接口也可以获取那些数据。还有就是我们ETH现在出现空块的情况比较多，请教有没有一些建议

de1acr0ix commented 5 years ago

我们的处理逻辑里面包含了一些判断需要除去原始 eth_getWork 字段之外的一些内容，比如 gas used/limit 以及叔块数量等等，这些都是待挖区块的参数。虽然确实有其它 RPC 可以获取这些内容并且我们其实是调用了的，但是获取待挖区块参数的 RPC 已经被标记为 deprecated 了，所以我们自行修改了 eth_getWork 接口增加了这些参数。

另外一个方面是，我们自行修改的接口还提供了 RLP 编码的区块头，并且我们自己的 sserver 目前提供了一个功能可以在区块头的 extra data 字段后面为每一个用户添加不同的内容，这样每一个用户的挖矿任务均不相同，这可以防止一些特殊的攻击。

我们修改的 geth 和 parity 代码都是公开的，可以在 https://github.com/btccom/go-ethereum 和 https://github.com/btccom/parity-ethereum 找到（对应分支都带有 btcpool 后缀）。

明白，感谢，geth和pairty两个版本，用你们改的v1.9.2和v2.5.7最新版可以吗？还有就是请教大佬，因为eth是没有办法构建空块的，所以我们挖出来的空块比例高，是不是我们全节点同步消息有些问题，没有拉取到更多的交易进来，所以请求pending的块任务的时候，里面没有交易，导致挖出来的是空块

de1acr0ix commented 5 years ago

这两个版本是可以的，这两个软件还是有一些区别的。

空块任务过多可能是你说的原因，但是这很不常见，你可以 geth attach 进入节点的控制台，然后调用 txpool.status 来查看内存池是否交易量很少来确认。另一个可能的原因则是我们以前版本的代码实际上存在一些 bug 导致空块判断错误，建议你重新构建最新版本的矿池代码进行测试。

rocqina commented 5 years ago

好的，我之前理解是需要两个类型全节点，parity notify走Parity，rpc拉取走geth。如果只有一个geth就没有办法获得新块的推送，但是貌似如果只有parity既可以有新块推送也可以rpc定时拉取到，但是有性能问题。大神上面的回复，是也同时连接2个类型的全节点吗，还是只有一个geth也够了

de1acr0ix commented 5 years ago

Geth 现在也支持新任务通知，可以使用 miner.notify 这个命令行参数指定。

f53e62c731cf3bb3ad0ce4a40820992d3b92d388,我用的是8月21号的版本，代码也算是很新的版本。我检查了全节点的交易池，pending4000多，queue500多，看起来也没什么问题。因为我们也不是每个块都是空块，但是50%出得块是空块，这个很奇怪。

image 空块的概率如图

de1acr0ix commented 5 years ago

我建议你贴一下 gwmaker 和 jobmaker 的日志（去掉最后的 header 字段），以及使用的 geth 和 parity 版本（以及是否是用了我们的 fork 版本）。

用的是原生的geth1.8.23的版本,没用parity。新块通知之前没用起来，打算用--miner.notify='http://xxxx:xxxx/notify' 这个加到geth的启动命令上

其实从日志里就能看出一个比较大的问题了。

"height":8609465,"parent":"0xc33ec6a66a38b52b34a278e3e16be910255bbfef8fe372fdae56205d89a39a7b"

两个不同的块高是不可能有相同的上一区块哈希的，这说明 eth_getBlockByNumber 用参数 pending 获取待挖区块的功能不稳定，有时候会获取到上一个区块的字段。这时矿池获得的任务很可能是一个空任务，但是根据这个 RPC 的返回值我们就会认为它不空，之后获取到填充了交易的任务时也不会立刻下发了。要解决这个问题，换用我们 fork 的 geth/parity 就可以了。

rocqina commented 5 years ago

eth_getBlockByNumber 用参数 pending 获取待挖区块的功能不稳定，这是原生eth的程序bug吗？如果用原生eth岂不是挖矿都是有空块多的问题。btccom fork的geth，是通过什么思路解决这个bug的？

rocqina commented 5 years ago

还有关于不同的高度，父块hash相同，初步推测，是不是eth_getBlockByNumber 和eth_getWork 不同步导致，两边高度不一样，job的高度被eth_getWork 覆盖了，但是数据用的还是eth_getBlockByNumber 的数据，导致了高度不一样，但是父块的hash相同导致的，我看到日志里面block height mis-matched between getBlockByNumber(pending) and getWork()非常多

de1acr0ix commented 5 years ago

矿池调用 eth_getBlockByNumber 和 eth_getWork 是用的同一个 HTTP 请求的批处理调用，但是节点其实会拆分两个调用，它们可能发生在不同的 goroutine 或者线程中，所以确实是存在同步问题的。矿池代码中存在一些任务发送优化逻辑，比如我们判断当前一个任务为空而新任务不空时则立刻发送，这时就无法起作用了（如果完全没有这些逻辑反而是不会有问题了）。矿池 fork 的节点是扩展了 eth_getWork 调用，使其返回更多内容。

rocqina commented 5 years ago

还有一个问题想问一下，如果系统存在多个矿工的sessionid是一样的情况，现在btccom版本的geth，会有什么问题吗？因为原生节点不存在处理sessionid的问题。对于nicehash协议的eth矿工，截取两个字节从3个字节的sessionid作为extranonce，这个extranonce，不同的矿工很容易出现相同的情况。尽管分配id的时候跳间隔，但是还是会有相同的可能。这地方是不是只有结算有影响，fork后的全节点的改动对于爆块下发任务没什么影响，我想确认一下。

这个问题和改版的 geth 并没有什么关系，而是历史遗留问题。Session ID 相同时实际矿工应该是自己用随机值来填充剩下的字节，所以冲突情况并不多，真的出现冲突情况时会在统计模块中剔除。然而，如果 btcpool 决定不再支持原始的 geth 则这种情况反而就可以解决了，我们完全可以使用四个字节的 Session ID 来填充 extra data 字段，从而使每个矿工的任务完全不一样。

好的，感谢

@de1acr0ix 发现一个问题，用了分叉的geth，即使btccom实现的eth_getWork，仍然会在一个块的开始出现transactions:0的任务，过几条才会有交易被填充进来，这个现象是正常的吗？ I0929 06:12:11.329555 10119 GwMakerEth.cc:222] chain: ETH, topic: EthRawGw, parent:

首先 geth 导入区块之后一定会先生成一个空块任务，然后再填充交易生成非空块的任务。这实际上是对于挖矿的一种优化，因为填充交易需要相对不短的时间（数十毫秒到数百毫秒级别）。

这个日志看起来很不正常，是过滤了非空区块任务吗？一般来讲每个块高都会有若干个任务，第一个是空块，然后在几十到几百毫秒的区间出现第二个非空的任务。如果这就是完整的日志，那么需要查看一下 geth 的日志来看看任务生成的情况。

这是我过滤的，正常一两条之后就有填充交易的了。因为我发现还有空块的情况，所以确认一下这个现象

正常情况就是一条空块之后再接着一条已经填充交易的任务，两者间隔一般就是几十毫秒。实际爆块时，空块数量应该少于10%（这是一个粗略估计）。
