blockuncle以太坊
以太坊，Ethereum，簡稱ETH。2013年底，Vitalik發布以太坊白皮書，2014年7月，開始以太幣的預售。那時候圈內人稱這種代幣發行叫「幣眾籌」。通過為期42天的預售，以太坊團隊通過預售60102216個以太幣，募集了3萬多個比特幣；另外還對預售之前參與開發的早期貢獻者、長期從事項目研究的開發者分別按照當時以太幣發售總量的9.9%進行分配。所以以太坊正式發行時有 7200多萬個以太幣。以太坊預售結束後，採用工作量證明機制PoW進行挖礦，每年按照當時發行總量的26%獎勵礦工。2014年10月，以太坊將區塊的出塊時間從60秒縮減到了12秒，目前基本穩定在15秒，每個區塊獎勵5個以太幣。
雖然都是採用PoW挖礦機制，但是以太坊的出塊機制和比特幣還是有所區別。由於以太坊的出塊時間短，導致以太坊很容易形成孤塊，孤塊是指不在最長鏈上的區塊。比特幣的孤塊沒有任何區塊獎勵，但是在以太坊中，孤塊可以被引用，被引用的孤塊被稱為「叔塊」(uncle block)，它們打包的數據也會記錄在區塊鏈中。和比特幣不一樣，以太坊的叔塊有獎勵，每個叔塊最多可以獲得4.375個以太幣的獎勵。
以太坊是一個可編程的、圖靈完備的區塊鏈開發平台，相當於一個去中心化的全球計算機。在一個編程系統之上，通常會有一些編譯和執行的虛擬機來去做支撐。JAVA有JVM，在以太坊里，也有以太坊的虛擬機EVM，可以執行任意復雜的演算法代碼。開發者可以使用現有的JavaScript 或Python等編程語言，在以太坊上創造出自己想要的應用。通過以太坊的虛擬機，你可以很簡便地發行數字資產，編寫智能合約，建立和運行去中心化的應用，成立去中心化自治組織等。
以太幣（ETH）又被稱為以太坊內部的燃料。和幣類數字資產不同，以太坊除了用於轉賬，還用於支付智能合約的費用。
為了避免以太坊區塊鏈上充斥垃圾合約和垃圾應用，在以太坊上建立和運行智能合約，你必須用ETH支付智能合約費用。舉個例子，在以太坊區塊鏈上轉賬你新創造的數字資產，需要用ETH支付手續費，而不是你新創造的數字資產。

You know how people

That get you down. Like Bernie.
Bernie like to chew gum.
No, not chew. POP.
So I came home this one day
And I am really irritated, and I'm
looking for a bit of sympathy
and there's Bernie layin'
on the couch, drinkin' a beer
and chewin'. No, not chewin'.
Poppin'. So, I said to him,
I said, "you pop that
gum one more time..."
and he did.
So I took the shotgun off the wall
and I fired two warning shots...
...into his head.

[ANNIE (Spoken)]
I met Ezekiel Young from
Salt Lake city about two years ago
and he told me he was single
and we hit it off right away.
So, we started living together.
He'd go to work, he'd come home, I'd
fix him a drink, We'd have dinner.
And then I found out,
"Single" he told me?
Single, my ass. Not only
was he married
...oh, no, he had six wives.
One of those Mormons, you know. So that
night, when he came home, I fixed him
his drink as usual.
You know, some guys just can't hold
their arsenic.
[LIZ,ANNIE,JUNE,MONA]
Hah! He had it coming
He had it coming
He took a flower

It was a murder

My sister, Veronica and
I had this double act
and my husband, Charlie,
traveled around with us.
Now, for the last number in
our act, we did 20 acrobatic tricks
one two three four,five...splits, spread eagles,
back flips,flip flops,
one right after the other.
Well, this one night we were in the hotel Cicero,
the three of us,
boozin' and
havin' a few laughs
when we run out of ice.
So I went out to get some.
I come back, open the door
and there's Veronica and
Charlie doing Number Seventeen-
the spread eagle.
Well, I was in such a state of shock,
I completely blacked out.I can't remember a thing.
It wasn't until later,
when I was washing the blood off my hands
I even knew they were dead.
They had it coming
They had it coming
They had it coming all along
I didn't do it
But if I'd done it
How could you tell me that I was wrong?

I loved Alvin Lipschitz
more than I can possibly say.
He was a real artistic guy...
sensitive... a painter.
But
He was always trying
to find himself.
He'd go out every night
looking for himself
and on the way
he found Ruth,
Gladys,
Rosemary and Irving.
I guess you can say we broke
up because of artistic differences.
He saw himself as alive
and I saw him dead.

E. 非小號里以太坊jian簡況是什麼
1.在2013年底，有一些開發者開始提出以太坊概念，早期的發明者Vitalik Buterin（V神）提出以太坊應能運行任意形式（圖靈完備）的應用程序。
2.在2015年7月底，以太坊第一階段 Frontier 正式發布，標志著以太坊區塊鏈網路的正式上線。Frontier 版本實現了一些基礎功能，這一階段的用戶以開發者居多。
3.在2016年3月，第二階段 Homestead 開始運行（區塊數 1150000），主要提高了安全性和易用性，並有更多的用戶加入進來了。
4.在2016年6月，DAO（Decentralized Autonomous Organization ，去中心化自治組織） 基於以太坊平台進行眾籌，受到漏洞攻擊，造成價值超過 5000 萬美金的以太幣被凍結。社區最後通過硬分叉（Hard Fork）進行解決。
5.在2017年3月，以太坊成立以太坊企業級聯盟EEA（Enterprise Ethereum Alliance），聯盟成員主要來自摩根大通，微軟，芝加哥大學和部分創業企業等。
目前以太坊在不斷的更新完善，並且越來越多的人加入到了以太坊中。
特點
以太坊跟比特幣技術也類似，但還是有一些區別，以太坊主要有以下特點：
1.支持圖靈完備的智能合約，設計了編程語言 Solidity 和虛擬機 EVM
2.採用賬戶系統和世界狀態，而不是 UTXO，容易支持更復雜的邏輯
3.選用了內存需求較高的哈希函數，避免出現強算力礦機、礦池攻擊
4.叔塊（Uncle Block）激勵機制，降低礦池的優勢，並減少出塊時間（10 分鍾降低到 15 秒左右）
5.通過 Gas 限制代碼執行指令數，避免循環執行攻擊
6.目前是PoW 共識演算法，並計劃支持效率更高的 PoS 演算法
核心概念
跟比特幣相比，以太坊中提出了一些新的概率，包括：智能合約、以太幣、燃料、賬號等。下面將一一介紹。
智能合約
智能合約（Smart Contract）是以太坊中最為重要的一個概念。
以太坊支持通過圖靈完備的高級語言（包括 Solidity、Serpent、Viper）等來開發智能合約。智能合約作為運行在以太坊虛擬機（Ethereum Virual Machine，EVM）中的應用，可以接受來自外部的交易請求和事件，通過觸發運行提前編寫好的代碼邏輯，進一步生成【摘要】
非小號里以太坊jian簡況是什麼【提問】
以太坊的概念建立區塊鏈和密碼學貨幣之上，不熟悉區塊鏈和比特幣的讀者可以先去看看《比特幣的簡介》和《區塊鏈技術的簡介》。【回答】
你說的簡介就是簡況？【提問】
請問就是指的以太坊是吧【回答】
1.在2013年底，有一些開發者開始提出以太坊概念，早期的發明者Vitalik Buterin（V神）提出以太坊應能運行任意形式（圖靈完備）的應用程序。

。點簡況進入區塊站能搜索到一個代幣的轉轉帳記錄嗎【提問】
我想查一個幣種叫BBGO，想核實一下BBGO是不是基於以太坊2.0ERC開發出來的代幣？
【提問】
有人在嗎？【提問】
您好，剛才去查詢了。搜索不到哦【回答】
F. 以太幣是什麼
以太坊Ethereum是一個區塊鏈。它與比特幣相比特點是可以增加智能合約，圖靈完備，網路速度更快。Etherem上有很多區中心化的區塊鏈產品，比如DigixDAO，黃金物聯網等等。
G. 以太坊架構是怎麼樣的
以太坊最上層的是DApp。它通過Web3.js和智能合約層進行交換。所有的智能合約都運行在EVM（以太坊虛擬機）上，並會用到RPC的調用。在EVM和RPC下面是以太坊的四大核心內容，包括：blockChain, 共識演算法，挖礦以及網路層。除了DApp外，其他的所有部分都在以太坊的客戶端里，目前最流行的以太坊客戶端就是Geth（Go-Ethereum）
H. 以太坊能量幣是傳銷嗎
以太坊能量幣不是傳銷。
以太坊是一個開源的有智能合約功能的公共區塊鏈平台。通過其專用加密貨幣以太幣提供去中心化的虛擬機（稱為「以太虛擬機」Ethereum Virtual Machine）來處理點對點合約。
2013年，19歲的Vitalik Buterin在一本主題為「以太坊白皮書：下一代智能連接與去中心化應用平台」的書中首次提到了以太幣的構想。隨後在2014年，以太幣的演算法及協議正式落地，並募集了1.5億美元，系統本身於2015年7月30日最終完成。
作為區塊鏈2.0代表，主流幣種以太幣被視作加密數字貨幣市場風向標。不過，最近一周來，以太幣價格持續下跌。2018年08月14日，以太幣暴跌20%，最低觸到257美元，創今年來歷史新低。相較於今年最高點1295美元，以太幣價格縮水逾八成。受其影響，2018年08月15日數字貨幣市場排名前十的主流幣種無一倖免，全線下跌，多個單日跌幅超10%。

以太坊差不多在2013年開始規劃，到2015年項目開始落地。在此之前，市場上有不少模仿比特幣的數字貨幣，他們在比特幣代碼的基礎上，做的各種修改。這樣要開發一個新的區塊鏈應用，要重新部署一個新鏈，再在這個鏈上開發應用，開發的難度非常大，單單使用一個POW的共識機制，就是個巨大的維護工作量。這就好比要在手機上開發一個APP，要把安卓系統一起開發出來。
以太坊出來以後，就相當於區塊鏈的底層操作系統，在以太坊上，可以很方便的開發各種DAPP，不用考慮底層的開發，而且還可以共享以太坊的算力和存儲。這對程序員來說，瞬間降低了區塊鏈的開發門檻，以太坊的出現，對區塊鏈應用的開發普及起到了非常大的作用。這也是以太坊被稱為區塊鏈2.0的原因。
I. eth挖礦是什麼原理
凡是涉及到幣，就一定離不開挖礦。以太坊網路中，想要獲得以太坊，也要通過挖礦來實現。說到挖礦，就一定離不開共識機制。
不知道大家還記得比特幣的共識機制是什麼嗎？比特幣的共識機制是 PoW (這是英文 Proof of Work 的縮寫，意思是「工作量證明機制」）。簡單來說，就是多勞多得，你付出的計算工作越高，那麼你就越有可能第一個找到正確的哈希值，就越有可能得到比特幣獎勵。
但是，比特幣的PoW存在著一定的缺陷，就是它處理交易的速度太慢，礦工們需要不斷地通過計算來碰撞哈希值，這是勞民傷財且效率低下的。對區塊鏈知識有涉獵的朋友們應該看到這樣一種說法：
以太坊為了彌補比特幣的不足，提出了新的共識機制，名叫 PoS(這是英文的縮寫，意思是「權益證明」，也有翻譯成「股權證明」的）。
PoS 簡單來講，其實就跟它的字面意思一樣：權益嘛，股權嘛，你持有的幣越多相當於你的股權越多，你的權益越高。
以太坊的PoS就是說：你持幣越多，你持有幣的時間越久，你的計算難度就會降低，挖礦會容易一些。
在以太坊最初的設定中，以太坊希望能夠通過階段性的升級，在前期依舊採用PoW來構建一個相對穩定的系統，之後逐漸採用 PoW+PoS，最後完全過渡到 PoS。所以，說以太坊的共識機制是PoS，沒錯，但是PoS只是以太坊發布之初的一個計劃或者說目標，目前以太坊還沒有過渡到 PoS，以太坊採用的共識機制仍是 PoW，就是比特幣那個 PoW，但是又和比特幣的PoW稍稍不同。
這里的信息量有點大，
第一個信息點是：以太坊目前採用的共識機制也是PoW，但是和比特幣的PoW稍稍不同。那麼，和比特幣的PoW到底有什麼不同呢：簡單來說，就是以太坊挖礦難度可以調節，比特幣挖礦難度不能調節。就好比咱們高考，因為各個省份的教學情況、生源人數都不一樣，所以高考分為全國卷和各省自主命題。
以太坊說我贊成這樣分地區出題，比特幣說：不行，必須全國同一卷，大家難度都一樣！
通俗解釋，就是，比特幣是利用計算機算力做大量的哈希碰撞，列舉出各種可能性，來找到一個正確哈希值。而以太坊系統呢，它有一個特殊的公式用來計算之後的每個塊的難度。如果某個區塊比前一個區塊驗證的更快，以太坊協議就會增加區塊的難度。通過調整區塊難度，就可以調整驗證區塊所需的時間。
以太坊協議規定，難度的動態調整方式是使全網創建新區塊的時間間隔為 15 秒，網路用 15 秒時間創建區塊鏈，這樣一來，因為時間太快，系統的同步性就大大提升，惡意參與者很難在如此短的時間發動51%（也就是半數以上）的算力去修改歷史數據。
第二個信息點是：以太坊最初的設定中，希望通過階段性升級來最終實現由 PoW 向
PoS過渡的。
時間追溯到 2014 年，在以太坊發布之初，團隊宣布將項目的發布分為四個階段，即 Froniter（前沿）、Homestead（家園）、Metropolis（大都會）和 Serenity（寧靜）。前三個階段共識機制採用 PoW（工作量證明機制），第四個階段切換到 PoS（權益證明機制）。
2015年7月30號，以太坊第一個階段「前沿」正式發布，這個階段只適用於開發者使用，開發人員可於在以太坊網路上編寫智能合約和去中心化應用程序 DAPP，礦工開始進入以太坊網路維護網路安全並挖礦得到以太幣。前沿版本類似於測試版，證明以太坊網路到底是不是可靠的。
2016年3月14日，以太坊進入到第二個階段「家園」，這一階段，以太坊提供了錢包功能，讓普通用戶也可以方便體驗和使用以太坊。其他方面沒有什麼明顯的技術提升，只是表明以太坊網路已經可以平穩運行。
2017 年 9 月，以太坊已經進行到第三個階段「大都會」。「大都會」由拜占庭和君士坦丁堡兩次升級組成，這個階段的的目標是希望能夠引入 PoW 和 PoS 的混合鏈模式，為 PoW向PoS的順滑過渡做准備。最近比較熱門的「以太坊君士坦丁堡升級」升級的就是這個，在君士坦丁堡升級中呢，以太坊將對底層協議和演算法做一些改變，來為實現 PoW 和
PoS奠定良好的基礎。
以太坊挖礦會得到對多少獎勵呢？贏得區塊創建競爭成功的礦工會得到這么幾項收入：
1、 靜態獎勵，5個以太坊；
2、 區塊內所花費的燃料成本，也就是Gas，這部分我們上一期內容講過;
3、 作為區塊組成部分，包含「叔區塊」的額外獎勵，叔就是叔叔的叔，每個叔區塊可以得到挖礦報酬的1/32作為獎勵，也就是5乘以1/32，等於0.15625 個以太坊。這里我們簡單解釋一下「叔區塊」，「叔區塊」這個概念是以太坊提出來的，為什麼要引進叔塊的概念？這還要從比特幣說起。在比特幣協議中，最長的鏈被認為是絕對的正確。如果一個塊不是最長鏈的一部分，那麼它被稱為是「孤塊」。一個孤立的塊是一個塊，它也是合法的，但是可能發現的稍晚，或者是網路傳輸稍慢，而沒有能成為最長的鏈的一部分。在比特幣中，孤塊沒有意義，隨後將被拋棄掉，發現這個孤塊的礦工也拿不到采礦相關的獎勵。
但是，以太坊不認為孤塊是沒有價值的，以太坊系統也會給與發現孤塊的礦工回報。在以太坊中，孤塊被稱為「叔塊」(uncle block)，它們可以為主鏈的安全作出貢獻。 以太坊十幾秒的出塊間隔太快了，會降低安全性，通過鼓勵引用叔塊，使引用主鏈獲得更多的安全保證(因為孤塊本身也是合法的) ，而且，支付報酬給叔塊，還能激發礦工積極挖礦，積極引用叔塊，所以，以太坊認為，它是有價值的。
