B. dydx能長期持有嗎

時間上,由於該策略風險較低,即使是行情波動時,也有足夠的時間增加保證金,因此可以長期持有該頭寸。也就是可以在整個Epoch的28天內維持不變。
最佳挖礦策略

隨著Epoch1臨近結束,dYdX的交易量激增。截至9月28日下午3點,根據CoinMarketCap的數據,過去24小時dYdX的交易量超過95億美元,是第二名Uniswap V3的8.5倍。類似的情況在Epoch0結束前也發生過,當時dYdX的24小時交易量超過10億美元,小幅超過Uniswap V3,短暫的位列第一。在Epoch0結束後,dYdX的交易量又再次被其它DEX超越。因此,當前大多數用戶都是為了交易挖礦而交易。

根據上述公式可以得知,交易分數由兩部分決定,一個是當前Epoch支付的手續費,一個是平均未平倉量。那麼,以交易挖礦為目的的用戶也可以拆解這兩部分,分別准備,從而最大效率地參與交易挖礦。

平均未平倉量

dYdX中要求的平均未平倉量也就是在這個Epoch中的平均持倉,比如某用戶僅在1天中以1萬美元為保證金,以2.8倍杠桿持有2.8萬美元的ETH多頭頭存,在24小時過去後平倉。那麼,在整個這個Epoch中,該用戶的平均未平倉量約為1000美元。可見,在資金量一定的情況下,交易挖礦應保證盡可能大的持倉量和持倉時間。

如何保證盡最佳的持倉量?我們知道,持倉量越大,意味著杠桿倍數越高,則更可能隨著市場的波動而爆倉。在dYdX的挖礦策略中,我們可以在賬戶中持有兩個方向相反的頭寸,比如以3倍杠桿做多BTC,同時以3倍杠桿做空ETH,總體上可以達到6倍杠桿。即使ETH/BTC匯率上漲20%,也不會爆倉。能夠及時補充保證金的用戶還可以在此基礎上增加杠桿。

雖然ETH相對於BTC的波動較小,該策略已經避免了爆倉風險,但仍然有本金虧損的風險。為了對沖ETH與BTC相對波動產生的風險,我們可以在另一個賬戶中持有和上述賬戶相反方向的頭寸。在這個例子中,另一個賬戶只需以同等本金,持有3倍BTC空頭頭寸和3倍ETH多頭頭寸。這樣可以完全避免價格波動和資金費率的影響。

C. ETH2.0出塊機制筆記

記錄一下自己的學習情況,可能有不對的地方,歡迎指正。

以太坊2.0中有兩個時間概念:時隙槽slot 和 時段(周期)epoch。其中一個slot為12秒,而每個 epoch 由 32 個 slots 組成,所以每個epoch共384秒,也就是 6.4 分鍾。

對於每個epoch,使用RANDAO偽隨機演算法將全部的驗證節點分成多個委員會(committee),這些委員會的職責主要包括出塊、LMD GHOST投票和Casper FFG投票。

每個委員會至少包括128個驗證節點,負責驗證一個slot。其中會隨機選擇一個驗證者作為區塊提議者,其餘驗證者負責LMD GHOST投票和Casper FFG投票。區塊提議者根據LMD-GHOST 分叉選擇規則構建下一個區塊,有4秒的時間去提議一個新區塊。

在區塊提議的過程中,可能出現分叉。當出現分叉時,要根據LMD GHOST投票結果確定主鏈。

檢查點(checkpoints)與區塊的最終確認(finalized)是區塊確認的關鍵步驟。檢查點是epoch中第一個slot的區塊,每個epoch必定有一個檢查點塊。當一個周期結束時,如果某檢查點獲得了所有活躍驗證者總有效余額 2/3 的投票支持,則該檢查點被認為是justified狀態。如果A被證明是justified,並且緊接的下一個epoch中的檢查點B也被證明是 justified 的,那麼A將被最終確認,變為finalized狀態。

所有最終確認(finalized)的檢查點都成為規范鏈(區塊鏈歷史的一部分),所有忠誠節點都默認接收規范鏈,即「最終檢查點」之後的區塊可以隨意分叉,但之前的區塊不允許分叉。所以,通過Casper FFG保證了ETH2.0的安全性。

信標鏈瀏覽器: beaconscan.com/

讓我們在信標鏈瀏覽器上查看一下epoch191896,可以看到該epoch的slot 6140674為forked,slot 6140676為skipped

對應的,在ETH區塊鏈瀏覽器上,可以看到16967454區塊在slot6140673被提議,16967455區塊在slot6140675被提議,中間正好隔了一個slot 6140674,因為該slot產生的區塊是一個分叉塊,且沒有在LMD Ghost獲得更多的投票weight。

可以看到16967456區塊在slot6140677被提議,與上一個區塊中間正好隔了一個slot 6140676,因為該slot沒有提議區塊,可能因為提議者離線了。

D. 【Discover ETH】什麼是權益證明PoS

本篇作為Discover系列文章的開篇,結合ETH2.0的目標,來談談權益證明PoS是什麼。

在談PoS之前,我們先來了解一下共識。共識,即達成了普遍協議。區塊鏈實質上是一個全球性的狀態機,達成共識意味著網路上至少有超過一半(51%)的節點同意網路的下一個全球狀態。
共識機制 (也稱為共識協議或共識演算法)允許分布式系統(計算機網路)協同工作並保持安全。當前主流的共識機制有兩種,分別是 工作量證明 (Proof of Work,PoW)和 權益證明 (Proof of Stake,PoS)。以太坊在設計之初就希望最終以太坊的共識機制能轉變為PoS,而PoW只作為一個過渡階段。但無論是PoW還是PoS,最終的目的都是相同的,即實現分布式計算機的共識機制。下面先簡單了解工作量證明(PoW)的工作機制。

工作量證明通過礦工們完成,礦工們需要競爭創建最新區塊以處理和完成交易。 獲勝者將與網路中的其他節點分享最新區塊,並且獲得最新的特定代幣區塊獎勵(如以太坊的以太幣)。由於用戶需要擁有超過網路中 51% 的算力才能夠欺騙整條鏈,因此網路安全得以保證。 這將需要巨大的設備和能源投入,所需的開支甚至可能超過收益。
工作量證明是08年在中本聰所創造的比特幣中提出的,至今已經經過了充分的考驗和測試,但隨著越來越多的礦工和礦池的加入,挖掘新的區塊的難度指數爆發式上升,也面臨的如下的問題:

PoS作為ETH2.0關鍵的建設目標,其作用不僅僅只是因為PoW帶來的環境不友好的能源消耗,還有PoS的建設能更有力支持 分片鏈 (以太坊網路擴展的關鍵升級),更強的去中心化特性等等。下面從幾個方面來簡單談談權益證明PoS的工作過程。

在以太坊中,工作量證明的過程參與的角色是礦工/礦池。其目的是通過算力試錯來反復計算,以此生成一個低於目標隨機數的混合哈希。這個計算難度依賴於區塊所聲明的 難度 ,難度越小,有效的哈希值的集合就越小。而在權益證明中,則沒有礦工這一角色,與之對應的是稱之為 驗證者 的角色。
在ETH2.0中,用戶需要質押 32ETH 來獲得作為驗證者的資格。驗證者被 信標鏈 隨機選擇去創建區塊,並且負責檢查和確認那些不是由他們創造的區塊。他們不需要開采區塊,他們只需要在被選中的時候創建區塊並且在沒有被選中的時候驗證他人提交的區塊。此驗證被稱為證明。
驗證者因提出新區塊和證明他們已經看到的區塊而獲得獎勵,對於一些惡意驗證者節點,也會有相應的懲罰機制使之失去質押。驗證者質押的ETH越多,獲得的獎勵也越多。可以這樣說,權益證明是一種用於激勵驗證者接受更多質押的機制。

前面提到了 分片鏈 這個名詞, 分片 就是將區塊鏈分成多條鏈。驗證者將會在不同的分片上處理它們的分片數據,以此來提高區塊鏈的工作效率。ETH2.0預計會有64個分片鏈。
驗證者會被隨機洗牌到不同的分片中,以防止驗證者惡意操縱節點並提高鏈的安全性。處理不同分片之間的數據的關鍵角色就是 信標鏈 (Beacon Chain)。
信標鏈 是協調分片信息、管理驗證者的連接不同分片的橋梁。
當用戶在分片上提交交易時, 驗證者 將負責將用戶的交易添加到分片區塊中。 信標鏈 通過演算法選擇驗證器以提出新的塊。如果一個驗證者沒有被選中提出一個新的分塊,它們將會證明另一個驗證者的提議,並確認一切都正常。
至少需要 128 個被稱為 委員會 committee )的驗證者來證明每個分片塊。委員會有一個提出和驗證分片區塊的時限,這個時限被稱為 插槽 Slot ),大約為12秒。 每個插槽只能創建一個有效區塊,一個 周期 Epoch ,大約6.4分鍾)有 32 個插槽。
每個周期過後,委員會都由不同的、隨機的參與者解散與重組,重組過程由一個半隨機演算法 RANDAO 來選擇,以此避免惡意節點的操縱。

ETH2.0使用 Cassper 終局協議來確認一個新的區塊是否得到足夠的證明,即只要2/3的插槽同意(即當前參與計算的2/3的驗證者節點),該區塊就會被最終確定。而推薦此區塊的驗證者將獲得獎勵。因此,在權益證明的機制下,每過6.4分鍾就會創建一個新的區塊。關於Cassper協議的詳細說明後續再進行探索。

權益證明的建設以太坊在15年就已經提出,截止至今也才完成了Phase 0信標鏈的建設。而下一階段的與主網合並,再下一階段的分片鏈建設也一再推遲。雖然PoS的建設非常緩慢,但無論如何,權益證明作為主流的共識機制演算法之一,也是值得我們探討其設計原理。
後續將會針對信標鏈的詳細設計、分片等ETH2.0內容進行探索。

是這個嗎。希望能幫到你

F. 什麼是金屬樂什麼是重金屬

重金屬:LAMB OF GOD
金屬樂:所有金屬類型的總稱:包括重金屬,激流金屬,鞭撻金屬,死亡金屬等;
前衛金屬:並非指打扮,是很有旋律感那種,很多迴旋樂句,新古典成分那種,x japan的長達半小時的歌曲就是了.還有一支很容易聽得出這種風格的叫vasailles.
布魯斯:聽下BB KING就知道了;
朋克:這個比較容易,吉他來來去去不超過四個和弦,多數都狂向下掃弦,聽起來比較有活力,陽光的.
英倫:披頭士;BEYOND
工業:德國戰車,SLIPNOT
獨立搖滾:還沒有公司簽的地下音樂,一般是發表於網路上的,或到處街頭表演的,目標是博得唱片關注.你作了搖滾歌曲,但沒人簽你約,你的歌也就是獨立了.
死亡/黑金:聽起來陰沉,但有強烈的節奏感.樂隊: Nile
日本視覺系:不同於華麗搖滾,華麗搖滾完全是認不出樂手本人的,化裝超厚,看下KISS,聖飢魔2就知道了.
日本視覺系是一定有陰柔的一面的,即使不是樂隊里的每個成員都女性化,但是一個樂隊里至少會有一個成員是女性化的.而華麗搖滾完全沒有女性化,多數是魔鬼化.視覺系不一定是玩搖滾的,也有玩電子等的.視覺只是為了舞台表現.
