以太坊（ETH）合并建筑师贾斯汀·德雷克（Justin Drake）表示，对比特币发动51％的攻击比以太坊更便宜。

以太坊的实施证明（POS）实施的建筑师贾斯汀·德雷克（Justin Drake）告诉Cointelegraph，对比特币发动51％的攻击比以太坊更便宜。

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

根据以太坊合并的建筑师贾斯汀·德雷克（Justin Drake）表示，对比特币（BTC）发动51％的攻击比以太坊（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的讲话时说，这将“比51％的攻击比特币便宜得多”，并且“按100亿美元的订单付款”。

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）领导了以太坊（Ethereum）实施（POS）实施的工作，并且是合并中的主要建筑师（完整的POS过渡事件）。他的讲话回应了5月14日X帖子，由以太坊市场和产品公司Etherealize的共同创始人Grant Hummer的帖子回应。

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

在帖子中，Hummer说，比特币“由于其安全预算而完全被搞砸了。”

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:

悍马声称，成功进行51％的进攻将花费80亿美元，而当成本滑到20亿美元时，成功的攻击实际上是“几乎可以肯定的”。当单个实体或组控制区块链网络的挖掘或放电功率的50％以上时，就会发生51％的攻击，从而在网络上获得电力。悍马补充说：

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10亿美元以下（大约是他们每年支付的薪水的一半！），他们可以轻松地保持对连锁店的控制。那时，他们可以偷走所有剩余的令牌。

Ethereum attack would cost much more

以太坊攻击将花费更多

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:

德雷克说：“要100％控制链，您需要50％ + 1的股份。”他说，这将非常困难和昂贵，但远非不可能：

It would be cheaper to 51% attack Bitcoin.

它比51％的攻击比特币便宜。

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.

在撰写本文时，有34,168,987个固定的Ether（ETH），价值近896亿美元。因此，所有ETH的一半的当前价值将近448亿美元。

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).

尽管如此，可能需要更高的投资。 Ether目前的市值为3160亿美元，交易量为250亿美元（占市值的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.

攻击所需的ETH价值近14.2％，占市值的14.2％，占24小时交易量的180％。该规模的承诺可能会引起大量的ETH价格赞赏，从而进一步增加了攻击的成本。

Ethereum’s last line of defense

以太坊的最后防线

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

区块链互操作性开发人员Lightbrocks的创始人兼首席执行官Matan Sitbon告诉Cointelegraph，以太坊具有额外的功能可以防御此类攻击。

“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.

他说：“以太坊的最终安全不仅在于密码学或协议规则，而在于社区强大的社会和经济协调机制。”

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.”

德雷克还强调了他声称以太坊比特币的另一个优势。他解释说：“如果有51％的攻击，社会层可以识别攻击者并在社交上削减它。”

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

他补充说：“这是POW无法使用的POS的超级大国。”

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的声明是指社交层，这意味着该网络的人类超级杂志决定要运行哪种软件。比特币更简单的工作证明（POW）共识机制具有较小的攻击表面和更长的可靠性记录，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的研究人员Pavel Yashin告诉Cointelegraph，“如果检测到集中化”，社区可以用新的叉子解决。旧的代币最终会被淘汰，而被折衷的链条将陷入无关紧要。

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.”

比特币流动性协议Ordeez首席执行官Hassan Khan告诉Cointelegraph，“围绕51％攻击的可行性的辩论仍然开放，这主要是因为虽然理论上可能有可能，但实际上，障碍非常高。”

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.”

他说，对于比特币而言，必要的计算能力和能源“使持续的攻击极不可能”，而对于以太坊，“ POS引入了其他经济和治理威慑”。
