这样支持BU的矿池就达到了9个而支持SW的矿池是4个网友回复lyf20617：不对，貌似是BTC.com的BUG，现在又显示BIP9了。网友回复bibini：看来BU扩容方案是大势所趋，core还坚持什么呢？网友回复：不错不错，支持一下。！网友回复画一方禁地：core一直在坚持不扩容主链的行为已经得不到大家的支持了

　　【比特币矿池】矿池偷我算力?谈谈挖矿那些门道
　　矿池偷我算力?为什么这矿池算力比全网算力还大?我怎么知道我大概一天能挖多少?
　　这些问题可以说是矿工圈的日经贴，本文将为你指点迷津。
　　全网算力是从何而来?
　　全网算力是根据近一段时间内的爆块速度与难度计算出来的，不是所有矿池加起来的算力。所以当大部分矿池&运气&不好时，矿池算力之和会远高于全网算力，反之亦然。
　　为什么要120个确认，不是只要6个吗?
　　120个确认为区块成熟的时间，与交易确认所需的6个不是一回事
　　我怎么知道我大概一天能挖多少?
　　不少矿工都是简单地从statistics/pool里面的估计值进行判断，举例如下:
　　矿池24小时出块数量*每块奖励/矿池平均算力全网24小时出块数量*每块奖励/全网平均算力
　　这是建立在全网算力波动不大的情况下的公式，矿池过去24小时的出块数量可以在statistics/blocks查询，平均算力有时需要自行估算。另外虽然上面两个公式看上去应该是等价的，但有时并不会这样，原因如何请看下文。
　　矿池&运气&是什么，真的只是运气吗?
　　众所周知，矿池运行挖矿算法进行挖矿，但每次算出来一个数的时间却有着较大的差异。矿池每次出块时间理论上由矿池算力与当前难度两方面决定，平均出块时间应等于：
　　block time * net hashrate/ pool hashrate #此货币出块时间*全网算力/矿池算力
　　但是由于各种原因 - 比如矿池配置差异 ，货币本身平均出块时间与理论不一致等。有时候矿池&运气&会长期不对，这里我们以CPU挖矿高收益币种CRYPLY举例：
　　上图为pool.cryply.io,下图为cryply.frogpool.work，此类信息可以在statistics/blocks中查询。&Shares Est&栏目代表的是预计所需要的share(可以简单理解为算力*时间)，&Shares&栏目代表的是实际花费的share，&Percentage&即为后者除以前者。理论上长期来说Percentage应该接近于100%，但是过去一周内上图矿池实际上多消耗了60%的算力。那么是否是上图矿池主作恶呢?我认为不是这样的，大部分这种情况并不能说明矿池主在&偷算力&，而往往是由于其他原因造成的。有时钱包自身难度计算方式有问题导致出块时间跟理论值差异很大，导致所有矿池&运气&不佳。即使外部条件无问题，显然更高的效率伴随着更大的服务器压力，可是矿工却未必能意识到这其中的差异，那么优化似乎并不能给矿池主带来好处。不过正是由于这种知识差距，靠租算力为生的我利用这种差异之前还能勉强盈利(现在快要破产了&&)。
　　小矿池有什么坏处?
　　小矿池最大的坏处是波动性太大，以yenten矿池yenten.frogpool.work举例：
　　由上图可知此矿池在上周竟然惊人地耗费了2倍的share才挖到块，很显然极少的出块量大大增加了出块的波动性
　　矿池偷我算力?
　　矿池偷算力这一事显然是真实存在的，唯一正确的检验方式是对照实验，实践是检验真理的唯一标准。上文所写的矿池&运气&问题，一样有作假的空间，但是矿池发到你钱包里面的币没法作假。不过一定要实验足够的时间才能够下判断，即使的确有着较大的差异，也可能是上文所说的并非矿池主故意而为，不过矿工自然可以根据自己的实验结果自行判断去哪儿挖矿。

3 / 3相关资讯Q: When will I get paid?
&A: This pool uses the following payout system.
Pay Per Last N Shares (PPLNS) - Block rewards are distributed among the last shares, disregarding round boundaries. In the accurate implementation, the number of shares is deter- mined so that their total will be a specified quantity of score (where the score of a share is the inverse of the difficulty). Most pools use a naive implementation based on a fixed number of shares or a fixed multiple of the difficulty. The share-variance can be reduced at the cost of increased maturity time, but there is no way to decrease the long-term pool-variance.
Q: What is a orphan block?
&A: Coins generated by a block will not be available to you right away. They will take some time to be confirmed by the entire network before you are allowed to transfer them out of the pool. Usually coins have a confirmation set to 120. What that actually means: the network (not the pool) has to discover 120 additional blocks on top of the one found by the pool to confirm it.
Q: What is estimated payout?
&A: Estimated payout is your estimated payout if a block is found at that time. This is an estimate according to your amount of shares submitted for the round(s).
Q: What is pool-variance?
&A: This is the variance caused by the pool being too small. Using a method with high pool-variance does no harm to large pools.
Q: What is a share?
&A: Finding blocks is not an easy task. Since it would take a really long time on some coins, finding a block is broken down into shares. Depending on the server side setting, each share can be a certain difficulty. The more difficult each share is to find by miners, the fewer total shares are required to eventually find a block.
On the server side, each share is checked against the coin daemon (a server side wallet with more features) if it is indeed a valid block solution. Every share computed has the potential to be a block solution. I will not go into details why this is, but rest assured that share estimates for blocks can sometimes be exceeded. In the long run though, shorter round with less shares than required will make up for those taking very long.
Keep in mind: shares are not blocks! Shares are part of a block and will count towards the block payout!
At times, you will see shares being rejected by the pool. This can happen if you try to send an outdated share right after a block was found. Stratum, a protocol used by a miner to request work from a server, is used for share submission and getting new work. It is very solid when it comes to avoiding rejects but they can still happen once in a while.
If you are seeing reject all the time, then something isn’t working right on your end. You may also notice that your hashrate on the pool website is not increasing while your invalid share count keeps climbing up. In that case turn off your miner and check your settings!
Q: I am having problems connecting to the pool.
