B. dydx能长期持有吗
时间上，由于该策略风险较低，即使是行情波动时，也有足够的时间增加保证金，因此可以长期持有该头寸。也就是可以在整个Epoch的28天内维持不变。
最佳挖矿策略
随着Epoch1临近结束，dYdX的交易量激增。截至9月28日下午3点，根据CoinMarketCap的数据，过去24小时dYdX的交易量超过95亿美元，是第二名Uniswap V3的8.5倍。类似的情况在Epoch0结束前也发生过，当时dYdX的24小时交易量超过10亿美元，小幅超过Uniswap V3，短暂的位列第一。在Epoch0结束后，dYdX的交易量又再次被其它DEX超越。因此，当前大多数用户都是为了交易挖矿而交易。
根据上述公式可以得知，交易分数由两部分决定，一个是当前Epoch支付的手续费，一个是平均未平仓量。那么，以交易挖矿为目的的用户也可以拆解这两部分，分别准备，从而最大效率地参与交易挖矿。
平均未平仓量
dYdX中要求的平均未平仓量也就是在这个Epoch中的平均持仓，比如某用户仅在1天中以1万美元为保证金，以2.8倍杠杆持有2.8万美元的ETH多头头存，在24小时过去后平仓。那么，在整个这个Epoch中，该用户的平均未平仓量约为1000美元。可见，在资金量一定的情况下，交易挖矿应保证尽可能大的持仓量和持仓时间。
如何保证尽最佳的持仓量？我们知道，持仓量越大，意味着杠杆倍数越高，则更可能随着市场的波动而爆仓。在dYdX的挖矿策略中，我们可以在账户中持有两个方向相反的头寸，比如以3倍杠杆做多BTC，同时以3倍杠杆做空ETH，总体上可以达到6倍杠杆。即使ETH/BTC汇率上涨20%，也不会爆仓。能够及时补充保证金的用户还可以在此基础上增加杠杆。
虽然ETH相对于BTC的波动较小，该策略已经避免了爆仓风险，但仍然有本金亏损的风险。为了对冲ETH与BTC相对波动产生的风险，我们可以在另一个账户中持有和上述账户相反方向的头寸。在这个例子中，另一个账户只需以同等本金，持有3倍BTC空头头寸和3倍ETH多头头寸。这样可以完全避免价格波动和资金费率的影响。
C. ETH2.0出块机制笔记
记录一下自己的学习情况，可能有不对的地方，欢迎指正。
以太坊2.0中有两个时间概念：时隙槽slot 和 时段（周期）epoch。其中一个slot为12秒，而每个 epoch 由 32 个 slots 组成，所以每个epoch共384秒，也就是 6.4 分钟。
对于每个epoch，使用RANDAO伪随机算法将全部的验证节点分成多个委员会（committee），这些委员会的职责主要包括出块、LMD GHOST投票和Casper FFG投票。
每个委员会至少包括128个验证节点，负责验证一个slot。其中会随机选择一个验证者作为区块提议者，其余验证者负责LMD GHOST投票和Casper FFG投票。区块提议者根据LMD-GHOST 分叉选择规则构建下一个区块，有4秒的时间去提议一个新区块。
在区块提议的过程中，可能出现分叉。当出现分叉时，要根据LMD GHOST投票结果确定主链。
检查点（checkpoints）与区块的最终确认（finalized）是区块确认的关键步骤。检查点是epoch中第一个slot的区块，每个epoch必定有一个检查点块。当一个周期结束时，如果某检查点获得了所有活跃验证者总有效余额 2/3 的投票支持，则该检查点被认为是justified状态。如果A被证明是justified，并且紧接的下一个epoch中的检查点B也被证明是 justified 的，那么A将被最终确认，变为finalized状态。
所有最终确认（finalized）的检查点都成为规范链（区块链历史的一部分），所有忠诚节点都默认接收规范链，即「最终检查点」之后的区块可以随意分叉，但之前的区块不允许分叉。所以，通过Casper FFG保证了ETH2.0的安全性。
信标链浏览器： beaconscan.com/
让我们在信标链浏览器上查看一下epoch191896，可以看到该epoch的slot 6140674为forked，slot 6140676为skipped
对应的，在ETH区块链浏览器上，可以看到16967454区块在slot6140673被提议，16967455区块在slot6140675被提议，中间正好隔了一个slot 6140674，因为该slot产生的区块是一个分叉块，且没有在LMD Ghost获得更多的投票weight。
可以看到16967456区块在slot6140677被提议，与上一个区块中间正好隔了一个slot 6140676，因为该slot没有提议区块，可能因为提议者离线了。
D. 【Discover ETH】什么是权益证明PoS
本篇作为Discover系列文章的开篇，结合ETH2.0的目标，来谈谈权益证明PoS是什么。
在谈PoS之前，我们先来了解一下共识。共识，即达成了普遍协议。区块链实质上是一个全球性的状态机，达成共识意味着网络上至少有超过一半（51%）的节点同意网络的下一个全球状态。
共识机制 （也称为共识协议或共识算法）允许分布式系统（计算机网络）协同工作并保持安全。当前主流的共识机制有两种，分别是 工作量证明 (Proof of Work，PoW)和 权益证明 (Proof of Stake，PoS)。以太坊在设计之初就希望最终以太坊的共识机制能转变为PoS，而PoW只作为一个过渡阶段。但无论是PoW还是PoS，最终的目的都是相同的，即实现分布式计算机的共识机制。下面先简单了解工作量证明（PoW）的工作机制。
工作量证明通过矿工们完成，矿工们需要竞争创建最新区块以处理和完成交易。 获胜者将与网络中的其他节点分享最新区块，并且获得最新的特定代币区块奖励（如以太坊的以太币）。由于用户需要拥有超过网络中 51% 的算力才能够欺骗整条链，因此网络安全得以保证。 这将需要巨大的设备和能源投入，所需的开支甚至可能超过收益。
工作量证明是08年在中本聪所创造的比特币中提出的，至今已经经过了充分的考验和测试，但随着越来越多的矿工和矿池的加入，挖掘新的区块的难度指数爆发式上升，也面临的如下的问题：
PoS作为ETH2.0关键的建设目标，其作用不仅仅只是因为PoW带来的环境不友好的能源消耗，还有PoS的建设能更有力支持 分片链 （以太坊网络扩展的关键升级），更强的去中心化特性等等。下面从几个方面来简单谈谈权益证明PoS的工作过程。
在以太坊中，工作量证明的过程参与的角色是矿工/矿池。其目的是通过算力试错来反复计算，以此生成一个低于目标随机数的混合哈希。这个计算难度依赖于区块所声明的 难度 ，难度越小，有效的哈希值的集合就越小。而在权益证明中，则没有矿工这一角色，与之对应的是称之为 验证者 的角色。
在ETH2.0中，用户需要质押 32ETH 来获得作为验证者的资格。验证者被 信标链 随机选择去创建区块，并且负责检查和确认那些不是由他们创造的区块。他们不需要开采区块，他们只需要在被选中的时候创建区块并且在没有被选中的时候验证他人提交的区块。此验证被称为证明。
验证者因提出新区块和证明他们已经看到的区块而获得奖励，对于一些恶意验证者节点，也会有相应的惩罚机制使之失去质押。验证者质押的ETH越多，获得的奖励也越多。可以这样说，权益证明是一种用于激励验证者接受更多质押的机制。
前面提到了 分片链 这个名词， 分片 就是将区块链分成多条链。验证者将会在不同的分片上处理它们的分片数据，以此来提高区块链的工作效率。ETH2.0预计会有64个分片链。
验证者会被随机洗牌到不同的分片中，以防止验证者恶意操纵节点并提高链的安全性。处理不同分片之间的数据的关键角色就是 信标链 （Beacon Chain）。
信标链 是协调分片信息、管理验证者的连接不同分片的桥梁。
当用户在分片上提交交易时， 验证者 将负责将用户的交易添加到分片区块中。 信标链 通过算法选择验证器以提出新的块。如果一个验证者没有被选中提出一个新的分块，它们将会证明另一个验证者的提议，并确认一切都正常。
至少需要 128 个被称为 委员会 （ committee ）的验证者来证明每个分片块。委员会有一个提出和验证分片区块的时限，这个时限被称为 插槽 （ Slot ），大约为12秒。 每个插槽只能创建一个有效区块，一个 周期 （ Epoch ，大约6.4分钟）有 32 个插槽。
每个周期过后，委员会都由不同的、随机的参与者解散与重组，重组过程由一个半随机算法 RANDAO 来选择，以此避免恶意节点的操纵。
ETH2.0使用 Cassper 终局协议来确认一个新的区块是否得到足够的证明，即只要2/3的插槽同意（即当前参与计算的2/3的验证者节点），该区块就会被最终确定。而推荐此区块的验证者将获得奖励。因此，在权益证明的机制下，每过6.4分钟就会创建一个新的区块。关于Cassper协议的详细说明后续再进行探索。
权益证明的建设以太坊在15年就已经提出，截止至今也才完成了Phase 0信标链的建设。而下一阶段的与主网合并，再下一阶段的分片链建设也一再推迟。虽然PoS的建设非常缓慢，但无论如何，权益证明作为主流的共识机制算法之一，也是值得我们探讨其设计原理。
后续将会针对信标链的详细设计、分片等ETH2.0内容进行探索。

是这个吗。希望能帮到你
F. 什么是金属乐什么是重金属
重金属:LAMB OF GOD
金属乐:所有金属类型的总称:包括重金属,激流金属,鞭挞金属,死亡金属等;
前卫金属:并非指打扮,是很有旋律感那种,很多回旋乐句,新古典成分那种,x japan的长达半小时的歌曲就是了.还有一支很容易听得出这种风格的叫vasailles.
布鲁斯:听下BB KING就知道了;
朋克:这个比较容易,吉他来来去去不超过四个和弦,多数都狂向下扫弦,听起来比较有活力,阳光的.
英伦:披头士;BEYOND
工业:德国战车,SLIPNOT
独立摇滚:还没有公司签的地下音乐,一般是发表于网络上的,或到处街头表演的,目标是博得唱片关注.你作了摇滚歌曲,但没人签你约,你的歌也就是独立了.
死亡/黑金:听起来阴沉,但有强烈的节奏感.乐队: Nile
日本视觉系:不同于华丽摇滚,华丽摇滚完全是认不出乐手本人的,化装超厚,看下KISS,圣饥魔2就知道了.
日本视觉系是一定有阴柔的一面的,即使不是乐队里的每个成员都女性化,但是一个乐队里至少会有一个成员是女性化的.而华丽摇滚完全没有女性化,多数是魔鬼化.视觉系不一定是玩摇滚的,也有玩电子等的.视觉只是为了舞台表现.
