以太經典升級網絡協議以確保仍可繼續採礦

 

在5月29日，根據ETC Block Explorer的數據，Ethereum Classic (ETC)已經成功地實現了一個協議升級，這將確保將來的挖掘仍然可行。

 

這款名爲「ECIP-1041」的叉子在590萬塊的網絡上移除所謂的「困難炸彈」功能。「炸彈」是最初的以太(ETH)代碼的一個組成部分，它被設計成指數級地增長採礦的難度，從而使其變得很是緩慢，從而觸發了向風險證實(PoS)一致性算法轉換的須要。這個特性一般被稱爲「Ethereum Ice Age」，由於它實際上會「凍結」塊驗證。

 

Ethereum的經典版本是在2016年因爲在如何處理DAO hack上的分歧而從最初的區塊鏈中獲得的。

 

特定於1041的協議升級不會致使空投，也不會產生新的令牌。

 

就其自己而言，在2017年10月，Ethereum採起行動，推遲了一年多來的困難，由於該基金會繼續爲過渡到其混合PoS系統，Casper奠基基礎。

 

一旦Ethereum移動到PoS, ETC的網絡——據報道沒有計劃向PoS轉移——可能但願繼承在其當前表單中使用的挖掘hashpower的重要部分。

 

PoS-PoW的辯論繼續將密碼社區劃分開來。就在本週，一名巴西研究人員計算出，只需55美圓的mln就能夠攻擊Ethereum Classic的網絡，從而得到1美圓的利潤，理由是該網絡的PoW算法比先前假設的攻擊更容易受到51%的攻擊。

Ethereum Classic (ETC) has now successfully implemented a protocol upgrade that will ensure that mining remains viable in future, according to ETC Block Explorer data yesterday, May 29.

 

The fork, dubbed ECIP-1041, has removed the so-called 「Difficulty Bomb」 feature from the ETC network at block 5,900,000. The ‘bomb’ was a component of the original Ethereum (ETH) code that was designed to exponentially increase the difficulty of mining to the point where it would become impractically slow, thereby triggering the need to transition to a Proof-of-Stake (PoS) consensus algorithm. This feature has commonly been referred to as the ‘Ethereum Ice Age,’ because it would essentially ‘freeze’ block validations.

 

Ethereum Classic formed after Ethereum hard-forked from the original blockchain in 2016 over disagreements in how to handle the DAO hack.

 

The ECIP-1041 protocol upgrade will not result in an AirDrop, nor in the creation of a new token.

 

For its part, in October 2017 Ethereum acted to postpone the difficulty bomb by over a year, as the Foundation continues to lay the groundwork for the transition to its hybrid PoS system, Casper.

 

Once Ethereum moves to PoS, ETC’s network – which reportedly has no plans to transition to PoS – could potentially hope to inherit a significant part of the mining hashpower dedicated to ETH in its current form.

 

The PoS-PoW debate continues to divide the crypto community. Just this week, a Brazilian researcher calculated that it could take just $55 mln to hack Ethereum Classic’s network to make $1 bln profit, arguing that the network’s PoW algorithm was more vulnerable to a 51% attack than previously assumed.
