㈠ Mining Pools
常見的幾種 :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的挖礦節點工作在類似比特幣區塊鏈的一種shares鏈上。由於沒有中心,所以也不會受到DoS攻擊。和其他現有的礦池技術都不一樣—每個節點工作的區塊,都包括支付給前期shares的所有者以及該節點自己的比特幣。99%的獎勵(50BTC+交易費用)會平均分給礦工,另外0.5%會獎勵給生成區塊的人。

結算模式
為了更好地讓利於礦工,BTC礦池於2月17日推出首創的 FPPS結算模式,即Full PPS(完全PPS),對包括交易費在內的全部區塊收益進行分配。 相比傳統的PPS結算模式(不分配交易費)可提升 5%-9% 左右收益。
什麼是幸運值?
礦池爆塊存在一定概率因素,爆塊速度時快時慢;幸運值在理論值100%上下浮動,當幸運值高時,礦池的收益會增大,反之減小,但這只會影響選擇PPLNS的用戶。
什麼是拒絕數?拒絕率?
拒絕數是指礦機提交的算力不符合伺服器要求,被伺服器拒絕的工作量。拒絕率是指拒絕數占總提交數的比例,數值越小,礦機的工作效率就越高。
為什麼礦機的算力會波動?
所有礦機都存在這樣的正常現象,礦機晶元的計算並不是一個穩定輸出的過程,只要平均算力和日收益是穩定的即可。除此之外,礦機算力還會因為礦機狀態、工作環境、網路不穩定等因素存在波動,礦場管理人員需要注意排查所有相關因素,保護收益的穩定。
什麼是爆塊/報塊?
比特幣協議規定全網每10分鍾會產生1個區塊,礦工完成計算任務,發現新的區塊後,會獲得約12.5個比特幣的獎勵,發現新區塊又被稱為爆塊或者報塊。

㈡ 什麼是區塊鏈擴容
擴容,是當某個容器或承載物不足以支撐或承載現有事物需求時,我們通過擴大容器的容量或承載物的體積來滿足日益增長的需求,從而緩解當前容器或承載物所受壓力的一種手段。
在比特幣誕生之初比特幣創始人中本聰並沒有特意限制區塊的大小,區塊最大可以達到32MB,當時平均每個區塊大小為1~2KB。
時比特幣用戶少,交易量也沒有那麼大,並不會造成區塊擁堵,然而2013年至今隨著比特幣價格的直線上升,用戶越來越多因此造成比特幣網路擁堵,用戶交易費用上升的問題逐漸涌現出來。
到現在,比特幣區塊鏈上最高時有幾十萬筆交易積壓,比特幣的平均交易費用比 2010 年 9 月上漲了 376 倍,每秒 7 筆交易的處理速度已經明顯無法滿足用戶需求,比特幣社區開始探索如何給比特幣「擴容」。
通過修改比特幣底層代碼,從而達到提高交易處理能力的目的。
比特幣擴容本身發展和設計方案有兩種,即第一層和第二層擴容技術。
· 第一層擴容技術即改進區塊鏈自身,把區塊鏈自身變得更快、容量變得更大,總的來說就是改變區塊鏈共識部分的內容。
· 第二層擴容技術目的是把計算移到鏈下,即通過側鏈的技術加以解決問題。
擴容協議及結局
擴容協議一般需要礦工們的支持,大致可以分為修改區塊大小、軟分叉、硬分叉、隔離見證等方式。
以比特幣舉例:
比特幣現在分裂成為大區塊Bitcoin Cash(BCH)和隔離見證。隔離見證現在是市場上公認的比特幣,而大區塊幣被冠名為比特現金。可以預見的往後的發展方向,比特幣將會以鏈下交易為主。包括閃電網路、側鏈。這兩個新東西目前不成熟,但是被很多人寄予厚望的。
比特幣將會大量發展隔離見證交易,並在隔離見證的基礎上做更多的衍生技術。最有可能是以技術推動比特幣往前發展。
比特現金將會以鏈上交易為主,重點發展貨幣功能,以降低交易摩擦為主要方式,以獲利更廣泛的鏈上用戶量為主要發展方向。
