Ethereum Merge architect Justin Drake informed Cointelegraph that it might be cheaper to launch a 51% attack on Bitcoin than on Ethereum.
Drake mentioned it might be “less expensive to 51% attack Bitcoin” and that it might price “on the order of $10 billion.”
Drake led work on Ethereum’s proof-of-stake (PoS) implementation and was a principal architect within the Merge (the total PoS transition occasion). His remarks echo a Might 14 X post by Grant Hummer, the co-founder of Ethereum-focused advertising and marketing and product firm Etherealize.
Within the put up, Hummer mentioned that Bitcoin “is totally screwed due to its safety price range.”
Hummer claimed it might price $8 billion to run a profitable 51% attack, and mentioned a profitable attack is “nearly sure” when the fee slips to $2 billion. A 51% attack happens when a single entity or group controls over 50% of a blockchain community’s mining or staking energy, gaining energy over the community. Hummer added:
“This may grow to be blindingly apparent over the following decade. ETH is the one really decentralized crypto-asset that may grow to be the web’s [store of value].“

Ethereum attack would price a lot more
Drake mentioned that “to have 100% management of the chain, you want 50% + 1 of stake.” He mentioned that it might be extraordinarily difficult and costly, however removed from not possible:
“A wealthy nation state can most likely pull it off.“
On the time of writing, there have been 34,168,987 staked Ether (ETH) value almost $89.6 billion. Consequently, half of all ETH has a present worth of just about $44.8 billion.
Nonetheless, a a lot greater funding would possible be wanted. Ether has a present market cap of $316 billion and a 24-hour buying and selling quantity of $25 billion (simply over 8% of the market cap).
The ETH wanted for an attack is value almost 14.2% of the market cap and 180% of the 24-hour buying and selling quantity. An endeavor of that measurement would possible trigger a major ETH value appreciation, additional rising the price of the attack.

Ethereum’s final line of protection
Matan Sitbon, the founder and CEO of blockchain interoperability developer Lightblocks, informed Cointelegraph that Ethereum has an extra function to defend in opposition to such assaults.
“Ethereum’s final safety lies not solely in cryptography or protocol guidelines, however locally’s highly effective social and financial coordination mechanisms,“ he mentioned.
Drake additionally highlighted one other benefit that he claims Ethereum has over Bitcoin. He defined that “if there’s a 51% attack, the social layer can establish the attacker and socially slash it.”
“This can be a superpower of PoS that isn’t obtainable with PoW,“ he added.
Drake’s assertion refers back to the social layer, that means the community’s human supermajority, which decides which software program to run. Bitcoin’s easier proof-of-work (PoW) consensus mechanism has a smaller attack floor and longer reliability observe report, however it lacks this function.
Pavel Yashin, Researcher at P2P.org, informed Cointelegraph that “if the centralization is detected,” the neighborhood may resolve it with a brand new fork. The previous token would find yourself being delisted, and the compromised chain would fall into irrelevancy.
Hassan Khan, CEO at Bitcoin liquidity protocol Ordeez, informed Cointelegraph that “the talk across the feasibility of a 51% attack stays open-ended — largely as a result of whereas theoretically attainable, in follow the boundaries are extraordinarily excessive.”
He mentioned that for Bitcoin, the required quantity of computing energy and power “makes a sustained attack extremely inconceivable,” whereas for Ethereum, “PoS introduces further financial and governance deterrents.”
