以太坊（ETH）社區研究員賈斯汀·德雷克（Justin Drake）建議比特幣（BTC）更容易攻擊51％

以太坊社區研究人員賈斯汀·德雷克（Justin Drake）認為，在比特幣網絡上執行51％的攻擊比嘗試對以太坊的類似攻擊要容易得多，而且昂貴。

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.

以太坊社區研究員賈斯汀·德雷克（Justin Drake）認為，與嘗試對以太坊的類似攻擊相比，對比特幣網絡進行51％的攻擊要容易得多，而且成本較低。

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，對比特幣的51％攻擊將非常昂貴，估計成本約為100億美元，但仍然有可能。相比之下，他認為以太坊由於其驗證證明（POS）安全性會更加困難，更昂貴，這將要求攻擊者至少控製網絡的至少一半。

"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."

“由於POS的攻擊，很難攻擊以太坊。目前，已有超過3400萬的ETH被固定在8,96億美元中。因此，要獲得51％的股份，需要支付約448億美元才能承擔大部分股份。”

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的採訪中，Drake是以太坊合併中的關鍵人物，該數字將網絡轉變為POS，進一步闡述了攻擊者在以太坊鍊為目標時面臨的獨特挑戰。

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.

他的講話與以以太坊公司Etherealize聯合創始人Grant Hummer的5月14日X帖子相吻合，他估計比特幣51％攻擊的成本約為80億美元。悍馬進一步建議，如果這筆成本降至20億美元，那麼對比特幣的成功攻擊幾乎是不可避免的。

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。謹慎地，由於其安全預算，BTC完全被搞砸了。今天的攻擊BTC僅為$ 8B至51％。當這降至$ 2B時（又名BTC的安全市值將佔其資產市值的0.1％），實際上肯定會發生51％的攻擊。這將…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.

悍馬還強調，比特幣最關鍵的問題是其“安全預算”，他認為這更重要，因為降低了維持比特幣網絡的採礦獎勵。

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.

隨著這些獎勵的降低，他建議單個實體統治網絡變得更加簡單，這種情況威脅到其分散系統。

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，德雷克還指出，攻擊者還需要克服以太坊的“社會層”國防層。以太坊安全的這一方面依賴於網絡社區的集體行動，該行動可以通過社會削減來識別和懲罰惡意演員，這是比特幣的工作證明（POW）框架中無法使用的過程。

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.

行業專家對此類攻擊的可行性表達了不同的看法。 LightBlocks首席執行官Matan Sitbon認為，即使以太坊通過密碼學是安全的，它確實取決於社區提供的支持。

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.

同時，Pavel Yashin表示，如果檢測到網絡是集中式的，以太坊可以通過分叉網絡來應對威脅，從而有效地隔離了受損的鏈條。

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.

比特幣流動性協議Ordeez首席執行官Hassan Khan承認了理論風險，但表示所需的大量能量使對比特幣的持續51％的攻擊不太可能，儘管其理論較高的脆弱性。
