blockuncle以太坊
以太坊，Ethereum，简称ETH。2013年底，Vitalik发布以太坊白皮书，2014年7月，开始以太币的预售。那时候圈内人称这种代币发行叫“币众筹”。通过为期42天的预售，以太坊团队通过预售60102216个以太币，募集了3万多个比特币；另外还对预售之前参与开发的早期贡献者、长期从事项目研究的开发者分别按照当时以太币发售总量的9.9%进行分配。所以以太坊正式发行时有 7200多万个以太币。以太坊预售结束后，采用工作量证明机制PoW进行挖矿，每年按照当时发行总量的26%奖励矿工。2014年10月，以太坊将区块的出块时间从60秒缩减到了12秒，目前基本稳定在15秒，每个区块奖励5个以太币。
虽然都是采用PoW挖矿机制，但是以太坊的出块机制和比特币还是有所区别。由于以太坊的出块时间短，导致以太坊很容易形成孤块，孤块是指不在最长链上的区块。比特币的孤块没有任何区块奖励，但是在以太坊中，孤块可以被引用，被引用的孤块被称为“叔块”(uncle block)，它们打包的数据也会记录在区块链中。和比特币不一样，以太坊的叔块有奖励，每个叔块最多可以获得4.375个以太币的奖励。
以太坊是一个可编程的、图灵完备的区块链开发平台，相当于一个去中心化的全球计算机。在一个编程系统之上，通常会有一些编译和执行的虚拟机来去做支撑。JAVA有JVM，在以太坊里，也有以太坊的虚拟机EVM，可以执行任意复杂的算法代码。开发者可以使用现有的JavaScript 或Python等编程语言，在以太坊上创造出自己想要的应用。通过以太坊的虚拟机，你可以很简便地发行数字资产，编写智能合约，建立和运行去中心化的应用，成立去中心化自治组织等。
以太币（ETH）又被称为以太坊内部的燃料。和币类数字资产不同，以太坊除了用于转账，还用于支付智能合约的费用。
为了避免以太坊区块链上充斥垃圾合约和垃圾应用，在以太坊上建立和运行智能合约，你必须用ETH支付智能合约费用。举个例子，在以太坊区块链上转账你新创造的数字资产，需要用ETH支付手续费，而不是你新创造的数字资产。

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.

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.

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. 非小号里以太坊jian简况是什么
1.在2013年底，有一些开发者开始提出以太坊概念，早期的发明者Vitalik Buterin（V神）提出以太坊应能运行任意形式（图灵完备）的应用程序。
2.在2015年7月底，以太坊第一阶段 Frontier 正式发布，标志着以太坊区块链网络的正式上线。Frontier 版本实现了一些基础功能，这一阶段的用户以开发者居多。
3.在2016年3月，第二阶段 Homestead 开始运行（区块数 1150000），主要提高了安全性和易用性，并有更多的用户加入进来了。
4.在2016年6月，DAO（Decentralized Autonomous Organization ，去中心化自治组织） 基于以太坊平台进行众筹，受到漏洞攻击，造成价值超过 5000 万美金的以太币被冻结。社区最后通过硬分叉（Hard Fork）进行解决。
5.在2017年3月，以太坊成立以太坊企业级联盟EEA（Enterprise Ethereum Alliance），联盟成员主要来自摩根大通，微软，芝加哥大学和部分创业企业等。
目前以太坊在不断的更新完善，并且越来越多的人加入到了以太坊中。
特点
以太坊跟比特币技术也类似，但还是有一些区别，以太坊主要有以下特点：
1.支持图灵完备的智能合约，设计了编程语言 Solidity 和虚拟机 EVM
2.采用账户系统和世界状态，而不是 UTXO，容易支持更复杂的逻辑
3.选用了内存需求较高的哈希函数，避免出现强算力矿机、矿池攻击
4.叔块（Uncle Block）激励机制，降低矿池的优势，并减少出块时间（10 分钟降低到 15 秒左右）
5.通过 Gas 限制代码执行指令数，避免循环执行攻击
6.目前是PoW 共识算法，并计划支持效率更高的 PoS 算法
核心概念
跟比特币相比，以太坊中提出了一些新的概率，包括：智能合约、以太币、燃料、账号等。下面将一一介绍。
智能合约
智能合约（Smart Contract）是以太坊中最为重要的一个概念。
以太坊支持通过图灵完备的高级语言（包括 Solidity、Serpent、Viper）等来开发智能合约。智能合约作为运行在以太坊虚拟机（Ethereum Virual Machine，EVM）中的应用，可以接受来自外部的交易请求和事件，通过触发运行提前编写好的代码逻辑，进一步生成【摘要】
非小号里以太坊jian简况是什么【提问】
以太坊的概念建立区块链和密码学货币之上，不熟悉区块链和比特币的读者可以先去看看《比特币的简介》和《区块链技术的简介》。【回答】
你说的简介就是简况？【提问】
请问就是指的以太坊是吧【回答】
1.在2013年底，有一些开发者开始提出以太坊概念，早期的发明者Vitalik Buterin（V神）提出以太坊应能运行任意形式（图灵完备）的应用程序。

。点简况进入区块站能搜索到一个代币的转转帐记录吗【提问】
我想查一个币种叫BBGO，想核实一下BBGO是不是基于以太坊2.0ERC开发出来的代币？
【提问】
有人在吗？【提问】
您好，刚才去查询了。搜索不到哦【回答】
F. 以太币是什么
以太坊Ethereum是一个区块链。它与比特币相比特点是可以增加智能合约，图灵完备，网络速度更快。Etherem上有很多区中心化的区块链产品，比如DigixDAO，黄金物联网等等。
G. 以太坊架构是怎么样的
以太坊最上层的是DApp。它通过Web3.js和智能合约层进行交换。所有的智能合约都运行在EVM（以太坊虚拟机）上，并会用到RPC的调用。在EVM和RPC下面是以太坊的四大核心内容，包括：blockChain, 共识算法，挖矿以及网络层。除了DApp外，其他的所有部分都在以太坊的客户端里，目前最流行的以太坊客户端就是Geth（Go-Ethereum）
H. 以太坊能量币是传销吗
以太坊能量币不是传销。
以太坊是一个开源的有智能合约功能的公共区块链平台。通过其专用加密货币以太币提供去中心化的虚拟机（称为“以太虚拟机”Ethereum Virtual Machine）来处理点对点合约。
2013年，19岁的Vitalik Buterin在一本主题为“以太坊白皮书：下一代智能连接与去中心化应用平台”的书中首次提到了以太币的构想。随后在2014年，以太币的算法及协议正式落地，并募集了1.5亿美元，系统本身于2015年7月30日最终完成。
作为区块链2.0代表，主流币种以太币被视作加密数字货币市场风向标。不过，最近一周来，以太币价格持续下跌。2018年08月14日，以太币暴跌20%，最低触到257美元，创今年来历史新低。相较于今年最高点1295美元，以太币价格缩水逾八成。受其影响，2018年08月15日数字货币市场排名前十的主流币种无一幸免，全线下跌，多个单日跌幅超10%。

以太坊差不多在2013年开始规划，到2015年项目开始落地。在此之前，市场上有不少模仿比特币的数字货币，他们在比特币代码的基础上，做的各种修改。这样要开发一个新的区块链应用，要重新部署一个新链，再在这个链上开发应用，开发的难度非常大，单单使用一个POW的共识机制，就是个巨大的维护工作量。这就好比要在手机上开发一个APP，要把安卓系统一起开发出来。
以太坊出来以后，就相当于区块链的底层操作系统，在以太坊上，可以很方便的开发各种DAPP，不用考虑底层的开发，而且还可以共享以太坊的算力和存储。这对程序员来说，瞬间降低了区块链的开发门槛，以太坊的出现，对区块链应用的开发普及起到了非常大的作用。这也是以太坊被称为区块链2.0的原因。
I. eth挖矿是什么原理
凡是涉及到币，就一定离不开挖矿。以太坊网络中，想要获得以太坊，也要通过挖矿来实现。说到挖矿，就一定离不开共识机制。
不知道大家还记得比特币的共识机制是什么吗？比特币的共识机制是 PoW (这是英文 Proof of Work 的缩写，意思是“工作量证明机制”）。简单来说，就是多劳多得，你付出的计算工作越高，那么你就越有可能第一个找到正确的哈希值，就越有可能得到比特币奖励。
但是，比特币的PoW存在着一定的缺陷，就是它处理交易的速度太慢，矿工们需要不断地通过计算来碰撞哈希值，这是劳民伤财且效率低下的。对区块链知识有涉猎的朋友们应该看到这样一种说法：
以太坊为了弥补比特币的不足，提出了新的共识机制，名叫 PoS(这是英文的缩写，意思是“权益证明”，也有翻译成“股权证明”的）。
PoS 简单来讲，其实就跟它的字面意思一样：权益嘛，股权嘛，你持有的币越多相当于你的股权越多，你的权益越高。
以太坊的PoS就是说：你持币越多，你持有币的时间越久，你的计算难度就会降低，挖矿会容易一些。
在以太坊最初的设定中，以太坊希望能够通过阶段性的升级，在前期依旧采用PoW来构建一个相对稳定的系统，之后逐渐采用 PoW+PoS，最后完全过渡到 PoS。所以，说以太坊的共识机制是PoS，没错，但是PoS只是以太坊发布之初的一个计划或者说目标，目前以太坊还没有过渡到 PoS，以太坊采用的共识机制仍是 PoW，就是比特币那个 PoW，但是又和比特币的PoW稍稍不同。
这里的信息量有点大，
第一个信息点是：以太坊目前采用的共识机制也是PoW，但是和比特币的PoW稍稍不同。那么，和比特币的PoW到底有什么不同呢：简单来说，就是以太坊挖矿难度可以调节，比特币挖矿难度不能调节。就好比咱们高考，因为各个省份的教学情况、生源人数都不一样，所以高考分为全国卷和各省自主命题。
以太坊说我赞成这样分地区出题，比特币说：不行，必须全国同一卷，大家难度都一样！
通俗解释，就是，比特币是利用计算机算力做大量的哈希碰撞，列举出各种可能性，来找到一个正确哈希值。而以太坊系统呢，它有一个特殊的公式用来计算之后的每个块的难度。如果某个区块比前一个区块验证的更快，以太坊协议就会增加区块的难度。通过调整区块难度，就可以调整验证区块所需的时间。
以太坊协议规定，难度的动态调整方式是使全网创建新区块的时间间隔为 15 秒，网络用 15 秒时间创建区块链，这样一来，因为时间太快，系统的同步性就大大提升，恶意参与者很难在如此短的时间发动51%（也就是半数以上）的算力去修改历史数据。
第二个信息点是：以太坊最初的设定中，希望通过阶段性升级来最终实现由 PoW 向
PoS过渡的。
时间追溯到 2014 年，在以太坊发布之初，团队宣布将项目的发布分为四个阶段，即 Froniter（前沿）、Homestead（家园）、Metropolis（大都会）和 Serenity（宁静）。前三个阶段共识机制采用 PoW（工作量证明机制），第四个阶段切换到 PoS（权益证明机制）。
2015年7月30号，以太坊第一个阶段“前沿”正式发布，这个阶段只适用于开发者使用，开发人员可于在以太坊网络上编写智能合约和去中心化应用程序 DAPP，矿工开始进入以太坊网络维护网络安全并挖矿得到以太币。前沿版本类似于测试版，证明以太坊网络到底是不是可靠的。
2016年3月14日，以太坊进入到第二个阶段“家园”，这一阶段，以太坊提供了钱包功能，让普通用户也可以方便体验和使用以太坊。其他方面没有什么明显的技术提升，只是表明以太坊网络已经可以平稳运行。
2017 年 9 月，以太坊已经进行到第三个阶段“大都会”。“大都会”由拜占庭和君士坦丁堡两次升级组成，这个阶段的的目标是希望能够引入 PoW 和 PoS 的混合链模式，为 PoW向PoS的顺滑过渡做准备。最近比较热门的“以太坊君士坦丁堡升级”升级的就是这个，在君士坦丁堡升级中呢，以太坊将对底层协议和算法做一些改变，来为实现 PoW 和
PoS奠定良好的基础。
以太坊挖矿会得到对多少奖励呢？赢得区块创建竞争成功的矿工会得到这么几项收入：
1、 静态奖励，5个以太坊；
2、 区块内所花费的燃料成本，也就是Gas，这部分我们上一期内容讲过;
3、 作为区块组成部分，包含“叔区块”的额外奖励，叔就是叔叔的叔，每个叔区块可以得到挖矿报酬的1/32作为奖励，也就是5乘以1/32，等于0.15625 个以太坊。这里我们简单解释一下“叔区块”，“叔区块”这个概念是以太坊提出来的，为什么要引进叔块的概念？这还要从比特币说起。在比特币协议中，最长的链被认为是绝对的正确。如果一个块不是最长链的一部分，那么它被称为是“孤块”。一个孤立的块是一个块，它也是合法的，但是可能发现的稍晚，或者是网络传输稍慢，而没有能成为最长的链的一部分。在比特币中，孤块没有意义，随后将被抛弃掉，发现这个孤块的矿工也拿不到采矿相关的奖励。
但是，以太坊不认为孤块是没有价值的，以太坊系统也会给与发现孤块的矿工回报。在以太坊中，孤块被称为“叔块”(uncle block)，它们可以为主链的安全作出贡献。 以太坊十几秒的出块间隔太快了，会降低安全性，通过鼓励引用叔块，使引用主链获得更多的安全保证(因为孤块本身也是合法的) ，而且，支付报酬给叔块，还能激发矿工积极挖矿，积极引用叔块，所以，以太坊认为，它是有价值的。
