Mining Pools
Reward types & explanation/Methods
常见的几种:PPLNS、PPS、DGM、P2Pool。
CPPSRB - Capped Pay Per Share with Recent Backpay.
DGM - Double Geometric Method. A hybrid between PPLNS and Geometric reward types that enables to operator to absorb some of the variance risk. Operator receives portion of payout on short rounds and returns it on longer rounds to normalize payments.
Double Geometric Method. 双几何制。 结合了 PPLNS 和几何奖励类型,使得矿池运营者能规避一部分风险。矿池运营者在短期内收取部分挖出的货币,然后在之后以正规化过的值返还给矿工,像电容充放电,运气好每 block 少给你点,运气差多给你点。
ESMPPS - Equalized Shared Maximum Pay Per Share. Like SMPPS, but equalizes payments fairly among all those who are owed.
POT - Pay On Target. A high variance PPS variant that pays on the difficulty of work returned to pool rather than the difficulty of work served by pool.
PPLNS - Pay Per Last N Shares. Similar to proportional, but instead of looking at the number of shares in the round, instead looks at the last N shares, regardless of round boundaries.
(最纯正的组队挖矿)全称Pay Per Last N Shares,意思是说“根据过去的N个股份来支付收益”,这意味着,所有的矿工一旦发现了一个区块,大家将根据每个人自己贡献的股份数量占比来分配区块中的货币。(share就是股份的意思)举个例子:假设,张三、李四、王五,这三个人在同一个PPLNS矿池中挖矿,在过去的一段时间里,张三贡献了10个股份,李四贡献3个,王五贡献12个,加起来是25个股份,这时矿池发现了一个区块,区块中含有25个比特币,那么,张三就会分到10/25个区块的奖励,也就是10个比特币,而李四获得3个,王五获得12个。
在PPLNS模式下,运气成份非常重要,如果矿池一天能够发现很多个区块,那么大家的分红也会非常多,如果矿池一天下来都没有能够发现区块,那么大家也就没有任何收益。同时,由于PPLNS下,具有一定的滞后惯性,你的挖矿收益会有一定的延迟,比如说,你加入到一个新的PPLNS矿池,这个时候你会发现前面几个小时的收益比较低,那是因为别人在这个矿池里已经贡献了很多个share了,你是新来的,你的贡献还很少,所以分红时你的收益都是比较低的。随着时间的推移,该结算的也结算了,大家又开始进行了新一轮的运算时,你就回到和别人一样的水平了。同样道理,若你离开了PPLNS矿池不再挖矿,你贡献的share还在,在此后的一段时间里,你依然会得到分红收益,直到你的share被结算完毕。
PPLNSG - Pay Per Last N Groups (or shifts). Similar to PPLNS, but shares are grouped into "shifts" which are paid as a whole.
PPS - Pay Per Share. Each submitted share is worth certain amoutripnt of BC. Since finding a block requires <current difficulty> shares on average, a PPS method with 0% fee would be 12.5 BTC divided by <current difficulty>. It is risky for pool operators, hence the fee is highest.
Pay-Per-Share方式—该方式为立即为每一个share支付报酬。该支出来源于矿池现有的比特币资金,因此可以立即取现,而不用等待区块生成完毕或者确认。这样可以避免矿池运营者幕后操纵。这中方法减少了矿工的风险,但将风险转移给了矿池的运营者。运营者可以收取手续费来弥补这些风险可能造成的损失。 为了解决PPLNS那种有时候收益很高,有时候没有收益的情况,PPS采用了新的算法。PPS根据你的算力在矿池中的占比,并估算了矿池每天可以获得的矿产,给你每天基本固定的收益。
这么举例就很好理解:假设你的算力是100M,而整个矿池的算力是10000M,那么你就占据了矿池算力的1%,然后,假设矿池根据当前的难度和全球总算力,估算出矿池一天大约能够挖到4个区块,也就是100个比特币,那么,矿池会为你每天支付全矿池1%,也就是1个比特币的报酬,这样,即使矿池今天只挖到了1个区块,你也是获得1个比特币(矿池亏本),如果矿池超额发挥,挖到了10个区块,你还是只有1个比特币的收益(矿池大赚)。
怎么样,有没有感觉这就是一个稳定的工作?实际上,PPS模式的矿池为了避免亏本风险,往往会收取7%-8%的高额手续费。
Prop. - Proportional. When block is found, the reward is distributed among all workers proportionally to how much shares each of them has found.
RSMPPS - Recent Shared Maximum Pay Per Share. Like SMPPS, but system aims to prioritize the most recent miners first.
Score - Score based system: a proportional reward, but weighed by time submitted. Each submitted share is worth more in the function of time t since start of current round. For each share score is updated by: score += exp(t/C). This makes later shares worth much more than earlier shares, thus the miner's score quickly diminishes when they stop mining on the pool. Rewards are calculated proportionally to scores (and not to shares). (at slush's pool C=300 seconds, and every hour scores are normalized)
SMPPS - Shared Maximum Pay Per Share. Like Pay Per Share, but never pays more than the pool earns.
FPPS - Full Pay Per Share. Similar to PPS,but not only divide regular block reward (12.5 BTC for now) but also the transaction fee. Calculate a standard transaction fee within a certain period and distribute it to miners according to their hash power contributions in the pool. It will increase the miners' earnings by 7%-11%.
P2Pool - P2Pool的挖矿节点工作在类似比特币区块链的一种shares链上。由于没有中心,所以也不会受到DoS攻击。和其他现有的矿池技术都不一样—每个节点工作的区块,都包括支付给前期shares的所有者以及该节点自己的比特币。99%的奖励(50BTC+交易费用)会平均分给矿工,另外0.5%会奖励给生成区块的人。

幸运值
每个区块的幸运值是矿池实际工作量与挖矿难度之比。如果工作量小于难度,说明运气比较好,幸运值就越高。挖矿的运气成分很大,幸运值发生波动也很常见,但挖矿时间越久,总幸运值越接近 100%。
拒绝率
矿池统计 矿池首页 结算方式根据矿池的工作原理,矿池不断给矿机下发新的计算任务,矿机将计算结果提交给矿池。但是由于矿机与矿池的网络连接是有延迟的,从矿池下发新的挖矿高度的任务给矿机,到矿机接收到任务,在这段时间提交的结果已经过时,将不被矿池承认。拒绝率即无效提交与总提交结果之比。

结算模式
为了更好地让利于矿工,BTC矿池于2月17日推出首创的 FPPS结算模式,即Full PPS(完全PPS),对包括交易费在内的全部区块收益进行分配。 相比传统的PPS结算模式(不分配交易费)可提升 5%-9% 左右收益。
什么是幸运值?
矿池爆块存在一定概率因素,爆块速度时快时慢;幸运值在理论值100%上下浮动,当幸运值高时,矿池的收益会增大,反之减小,但这只会影响选择PPLNS的用户。
什么是拒绝数?拒绝率?
拒绝数是指矿机提交的算力不符合服务器要求,被服务器拒绝的工作量。拒绝率是指拒绝数占总提交数的比例,数值越小,矿机的工作效率就越高。
为什么矿机的算力会波动?
所有矿机都存在这样的正常现象,矿机芯片的计算并不是一个稳定输出的过程,只要平均算力和日收益是稳定的即可。除此之外,矿机算力还会因为矿机状态、工作环境、网络不稳定等因素存在波动,矿场管理人员需要注意排查所有相关因素,保护收益的稳定。
什么是爆块/报块?
比特币协议规定全网每10分钟会产生1个区块,矿工完成计算任务,发现新的区块后,会获得约12.5个比特币的奖励,发现新区块又被称为爆块或者报块。
