以太坊（ETH）社区研究员贾斯汀·德雷克（Justin Drake）建议比特币（BTC）更容易攻击51％

以太坊社区研究人员贾斯汀·德雷克（Justin Drake）认为，在比特币网络上执行51％的攻击比尝试对以太坊的类似攻击要容易得多，而且昂贵。

Ethereum community researcher Justin Drake suggests that executing a 51% attack on the Bitcoin network is much easier and less costly compared to attempting a similar attack on Ethereum.

以太坊社区研究员贾斯汀·德雷克（Justin Drake）认为，与尝试对以太坊的类似攻击相比，对比特币网络进行51％的攻击要容易得多，而且成本较低。

While Drake notes that a 51% attack on Bitcoin would be very expensive, at an estimated cost of around $10 billion, it is still possible. In contrast, he argues that Ethereum would be much harder and more expensive to attack due to its Proof-of-Stake (PoS) security, which would require an attacker to control at least half of the network.

德雷克（Drake）指出，对比特币的51％攻击将非常昂贵，估计成本约为100亿美元，但仍然有可能。相比之下，他认为以太坊由于其验证证明（POS）安全性会更加困难，更昂贵，这将要求攻击者至少控制网络的至少一半。

"It would be harder to attack Ethereum because of PoS. Right now, there are over 34 million ETH being staked, which is about $89.6 billion. So, to get 51% of the stake would require paying about $44.8 billion to take over the majority of the stake."

“由于POS的攻击，很难攻击以太坊。目前，已有超过3400万的ETH被固定在8,96亿美元中。因此，要获得51％的股份，需要支付约448亿美元才能承担大部分股份。”

During an interview with Cointelegraph, Drake, a key figure in the Ethereum Merge that transitioned the network to PoS, further elaborated on the unique challenges an attacker would face when targeting the Ethereum chain.

在接受Cointelegraph的采访中，Drake是以太坊合并中的关键人物，该数字将网络转变为POS，进一步阐述了攻击者在以太坊链为目标时面临的独特挑战。

His remarks align with a May 14 X post by Grant Hummer, co-founder of Ethereum-focused company Etherealize, who estimated the cost of a Bitcoin 51% attack at around $8 billion. Hummer further suggested that if this cost drops to $2 billion, a successful attack on Bitcoin is almost inevitable.

他的讲话与以以太坊公司Etherealize联合创始人Grant Hummer的5月14日X帖子相吻合，他估计比特币51％攻击的成本约为80亿美元。悍马进一步建议，如果这笔成本降至20亿美元，那么对比特币的成功攻击几乎是不可避免的。

1. Respectfully, BTC is completely screwed because of its security budget. It would only cost $8B to 51% attack BTC today. When this gets down to $2B (AKA, BTC's security market cap becomes 0.1% of its asset market cap), a 51% attack is virtually certain to happen. This will… pic.twitter.com/ZtP8gH9y4c

1。谨慎地，由于其安全预算，BTC完全被搞砸了。今天的攻击BTC仅为$ 8B至51％。当这降至$ 2B时（又名BTC的安全市值将占其资产市值的0.1％），实际上肯定会发生51％的攻击。这将…pic.twitter.com/ztp8gh9y4c

Hummer also highlights that the most critical issue for Bitcoin is its “security budget,” which he believes matters more as the mining rewards for maintaining the Bitcoin network are lessened.

悍马还强调，比特币最关键的问题是其“安全预算”，他认为这更重要，因为降低了维持比特币网络的采矿奖励。

With a lowering of these rewards, he suggests it becomes simpler for a single entity to dominate the network, a situation that threatens its decentralized system.

随着这些奖励的降低，他建议单个实体统治网络变得更加简单，这种情况威胁到其分散系统。

In addition to the high cost, Drake points out that an attacker would also need to overcome Ethereum’s “social layer” of defense. This aspect of Ethereum’s security relies on the collective action of the network’s community, which can identify and penalize malicious actors through social slashing, a process unavailable in Bitcoin’s proof-of-work (PoW) framework.

除了高昂的成本外，德雷克还指出，攻击者还需要克服以太坊的“社会层”国防层。以太坊安全的这一方面依赖于网络社区的集体行动，该行动可以通过社会削减来识别和惩罚恶意演员，这是比特币的工作证明（POW）框架中无法使用的过程。

Industry experts have expressed mixed opinions regarding the feasibility of such attacks. According to Matan Sitbon, the CEO of Lightblocks, even though Ethereum is secure through cryptography, it truly relies on the support provided by the community.

行业专家对此类攻击的可行性表达了不同的看法。 LightBlocks首席执行官Matan Sitbon认为，即使以太坊通过密码学是安全的，它确实取决于社区提供的支持。

Meanwhile, Pavel Yashin stated, if the network is detected to be centralized, Ethereum can deal with the threat by forking the network, effectively isolating compromised chains.

同时，Pavel Yashin表示，如果检测到网络是集中式的，以太坊可以通过分叉网络来应对威胁，从而有效地隔离了受损的链条。

Hassan Khan, CEO of Ordeez, a Bitcoin liquidity protocol, admitted to the theoretical risk but stated that the high amount of energy needed makes a sustained 51% attack on Bitcoin unlikely, despite its higher theoretical vulnerability.

比特币流动性协议Ordeez首席执行官Hassan Khan承认了理论风险，但表示所需的大量能量使对比特币的持续51％的攻击不太可能，尽管其理论较高的脆弱性。
