Ethereum Merge architect Justin Drake instructed Cointelegraph that he believes it could be cheaper to launch a 51% attack on Bitcoin than on Ethereum.
Drake stated it could be “less expensive to 51% attack Bitcoin” and that it could value “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 May 14 X post by Grant Hummer, the co-founder of Ethereum-focused advertising and product firm Etherealize.
In the put up, Hummer stated that Bitcoin “is totally screwed due to its safety funds.”
Hummer claimed it could value $8 billion to run a profitable 51% attack, and he expects a profitable attack to be “nearly sure” when the price 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 will grow to be blindingly apparent over the subsequent decade. ETH is the one really decentralized crypto-asset that may grow to be the web’s [store of value].“

Ethereum attack would value a lot more
Drake defined that “to have 100% management of the chain, you want 50% + 1 of stake.” He stated that it could be extraordinarily difficult and costly, however removed from unattainable:
“A wealthy nation state can in all probability pull it off.“
At the time of writing, there was 34,168,987 staked Ether (ETH) price almost $89.6 billion. Consequently, half of all ETH has a present worth of just about $44.8 billion.
Still, a a lot larger funding would seemingly 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 price almost 14.2% of the market cap and 180% of the 24-hour buying and selling quantity. An enterprise of that measurement would seemingly trigger a major ETH value appreciation, additional growing the price of the attack.

Ethereum’s final line of protection
Matan Sitbon, the founder and CEO of blockchain interoperability developer Lightblocks, instructed 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 in the neighborhood’s highly effective social and financial coordination mechanisms,“ he stated.
Drake additionally highlighted one other benefit that he believes 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 is a superpower of PoS that isn’t out there with PoW,“ he added.
Drake’s assertion refers back to the social layer, which 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 monitor file, nevertheless it lacks this function.
Pavel Yashin, Researcher at P2P.org, instructed Cointelegraph that “if the centralization is detected,” the group might 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, instructed Cointelegraph that “the controversy across the feasibility of a 51% attack stays open-ended — largely as a result of whereas theoretically potential, in apply the boundaries are extraordinarily excessive.”
He stated that for Bitcoin, the required quantity of computing energy and vitality “makes a sustained attack extremely inconceivable,” whereas for Ethereum, “PoS introduces further financial and governance deterrents.”
