㈠ Mining Pools
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.
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.
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.
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。

Stats
Pool DIstribution : Historical Distribution, Pool Distribution (calulate by blocks)
Block Size : Median daily block size, Average daily block size, Number of daily transactions, Sum of daily block size, etc.
Block Version : Version Trend, BIP109(Classic), SegWit, Bitcoin Unlimited.
Unconfirmed Transactions : Mempool Size, Distribution of Transaction Fees.
Difficulty : Next Difficulty Estimated, Date to Next Difficulty.
Transaction Fees : Tx fees per day, Tx fees % of block reward, Tx fees per KB (Tx fees/block size).
Address Rich List : Address Distribution, Balance Distribution
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。

㈡ 什么是区块链扩容
扩容,是当某个容器或承载物不足以支撑或承载现有事物需求时,我们通过扩大容器的容量或承载物的体积来满足日益增长的需求,从而缓解当前容器或承载物所受压力的一种手段。
在比特币诞生之初比特币创始人中本聪并没有特意限制区块的大小,区块最大可以达到32MB,当时平均每个区块大小为1~2KB。
时比特币用户少,交易量也没有那么大,并不会造成区块拥堵,然而2013年至今随着比特币价格的直线上升,用户越来越多因此造成比特币网络拥堵,用户交易费用上升的问题逐渐涌现出来。
到现在,比特币区块链上最高时有几十万笔交易积压,比特币的平均交易费用比 2010 年 9 月上涨了 376 倍,每秒 7 笔交易的处理速度已经明显无法满足用户需求,比特币社区开始探索如何给比特币“扩容”。
通过修改比特币底层代码,从而达到提高交易处理能力的目的。
比特币扩容本身发展和设计方案有两种,即第一层和第二层扩容技术。
· 第一层扩容技术即改进区块链自身,把区块链自身变得更快、容量变得更大,总的来说就是改变区块链共识部分的内容。
· 第二层扩容技术目的是把计算移到链下,即通过侧链的技术加以解决问题。
扩容协议及结局
扩容协议一般需要矿工们的支持,大致可以分为修改区块大小、软分叉、硬分叉、隔离见证等方式。
以比特币举例:
比特币现在分裂成为大区块Bitcoin Cash(BCH)和隔离见证。隔离见证现在是市场上公认的比特币,而大区块币被冠名为比特现金。可以预见的往后的发展方向,比特币将会以链下交易为主。包括闪电网络、侧链。这两个新东西目前不成熟,但是被很多人寄予厚望的。
比特币将会大量发展隔离见证交易,并在隔离见证的基础上做更多的衍生技术。最有可能是以技术推动比特币往前发展。
比特现金将会以链上交易为主,重点发展货币功能,以降低交易摩擦为主要方式,以获利更广泛的链上用户量为主要发展方向。
