以太坊（ETH）合併建築師賈斯汀·德雷克（Justin Drake）表示，對比特幣發動51％的攻擊比以太坊更便宜。

以太坊的實施證明（POS）實施的建築師賈斯汀·德雷克（Justin Drake）告訴Cointelegraph，對比特幣發動51％的攻擊比以太坊更便宜。

It would be cheaper to launch a 51% attack on Bitcoin (BTC) than on Ethereum (ETH), according to Ethereum Merge architect Justin Drake.

根據以太坊合併的建築師賈斯汀·德雷克（Justin Drake）表示，對比特幣（BTC）發動51％的攻擊比以太坊（ETH）便宜。

Speaking to Cointelegraph, Drake said that it would be “much cheaper to 51% attack Bitcoin” and that it would cost “on the order of $10 billion.”

德雷克（Drake）在接受Cointelegraph的講話時說，這將“比51％的攻擊比特幣便宜得多”，並且“按100億美元的訂單付款”。

Drake led work on Ethereum’s proof-of-stake (PoS) implementation and was a principal architect in the Merge (the full PoS transition event). His remarks echo a May 14 X post by Grant Hummer, the co-founder of Ethereum-focused marketing and product company Etherealize.

德雷克（Drake）領導了以太坊（Ethereum）實施（POS）實施的工作，並且是合併中的主要建築師（完整的POS過渡事件）。他的講話回應了5月14日X帖子，由以太坊市場和產品公司Etherealize的共同創始人Grant Hummer的帖子回應。

In the post, Hummer said that Bitcoin “is completely screwed because of its security budget.”

在帖子中，Hummer說，比特幣“由於其安全預算而完全被搞砸了。”

Hummer claimed it would cost $8 billion to run a successful 51% attack and that a successful attack is “virtually certain” when the cost slips to $2 billion. A 51% attack occurs when a single entity or group controls over 50% of a blockchain network’s mining or staking power, gaining power over the network. Hummer added:

悍馬聲稱，成功進行51％的進攻將花費80億美元，而當成本滑到20億美元時，成功的攻擊實際上是“幾乎可以肯定的”。當單個實體或組控制區塊鍊網絡的挖掘或放電功率的50％以上時，就會發生51％的攻擊，從而在網絡上獲得電力。悍馬補充說：

If the cost drops below $1 billion (about half of what they spend yearly on salaries!), they could easily maintain control of the chain for years. At that point, they could steal all the remaining tokens.

如果成本降至10億美元以下（大約是他們每年支付的薪水的一半！），他們可以輕鬆地保持對連鎖店的控制。那時，他們可以偷走所有剩餘的令牌。

Ethereum attack would cost much more

以太坊攻擊將花費更多

Drake said that “to have 100% control of the chain, you need 50% + 1 of stake.” He said that it would be extremely difficult and expensive, but far from impossible:

德雷克說：“要100％控制鏈，您需要50％ + 1的股份。”他說，這將非常困難和昂貴，但遠非不可能：

It would be cheaper to 51% attack Bitcoin.

它比51％的攻擊比特幣便宜。

At the time of writing, there were 34,168,987 staked Ether (ETH) worth nearly $89.6 billion. Consequently, half of all ETH has a current value of almost $44.8 billion.

在撰寫本文時，有34,168,987個固定的Ether（ETH），價值近896億美元。因此，所有ETH的一半的當前價值將近448億美元。

Still, a much higher investment would likely be needed. Ether has a current market cap of $316 billion and a 24-hour trading volume of $25 billion (just over 8% of the market cap).

儘管如此，可能需要更高的投資。 Ether目前的市值為3160億美元，交易量為250億美元（佔市值的8％以上）。

The ETH needed for an attack is worth nearly 14.2% of the market cap and 180% of the 24-hour trading volume. An undertaking of that size would likely cause significant ETH price appreciation, further increasing the cost of the attack.

攻擊所需的ETH價值近14.2％，佔市值的14.2％，佔24小時交易量的180％。該規模的承諾可能會引起大量的ETH價格讚賞，從而進一步增加了攻擊的成本。

Ethereum’s last line of defense

以太坊的最后防線

Matan Sitbon, the founder and CEO of blockchain interoperability developer Lightblocks, told Cointelegraph that Ethereum has an additional feature to defend against such attacks.

區塊鏈互操作性開發人員Lightbrocks的創始人兼首席執行官Matan Sitbon告訴Cointelegraph，以太坊具有額外的功能可以防禦此類攻擊。

“Ethereum’s ultimate security lies not solely in cryptography or protocol rules, but in the community’s powerful social and economic coordination mechanisms,” he said.

他說：“以太坊的最終安全不僅在於密碼學或協議規則，而在於社區強大的社會和經濟協調機制。”

Drake also highlighted another advantage that he claims Ethereum has over Bitcoin. He explained that “if there is a 51% attack, the social layer can identify the attacker and socially slash it.”

德雷克還強調了他聲稱以太坊比特幣的另一個優勢。他解釋說：“如果有51％的攻擊，社會層可以識別攻擊者並在社交上削減它。”

“This is a superpower of PoS that is not available with PoW,” he added.

他補充說：“這是POW無法使用的POS的超級大國。”

Drake’s statement refers to the social layer, meaning the network’s human supermajority, which decides which software to run. Bitcoin’s simpler proof-of-work (PoW) consensus mechanism has a smaller attack surface and longer reliability track record, but it lacks this feature.

Drake的聲明是指社交層，這意味著該網絡的人類超級雜誌決定要運行哪種軟件。比特幣更簡單的工作證明（POW）共識機制具有較小的攻擊表面和更長的可靠性記錄，但缺乏此功能。

Pavel Yashin, Researcher at P2P.org, told Cointelegraph that “if the centralization is detected,” the community could resolve it with a new fork. The old token would end up being delisted, and the compromised chain would fall into irrelevancy.

P2P.org的研究人員Pavel Yashin告訴Cointelegraph，“如果檢測到集中化”，社區可以用新的叉子解決。舊的代幣最終會被淘汰，而被折衷的鏈條將陷入無關緊要。

Hassan Khan, CEO at Bitcoin liquidity protocol Ordeez, told Cointelegraph that “the debate around the feasibility of a 51% attack remains open-ended — largely because while theoretically possible, in practice the barriers are extremely high.”

比特幣流動性協議Ordeez首席執行官Hassan Khan告訴Cointelegraph，“圍繞51％攻擊的可行性的辯論仍然開放，這主要是因為雖然理論上可能有可能，但實際上，障礙非常高。”

He said that for Bitcoin, the necessary amount of computing power and energy “makes a sustained attack highly improbable,” while for Ethereum, “PoS introduces additional economic and governance deterrents.”

他說，對於比特幣而言，必要的計算能力和能源“使持續的攻擊極不可能”，而對於以太坊，“ POS引入了其他經濟和治理威懾”。
