Ethereum Merge architect Justin Drake advised Cointelegraph that he believes it could be cheaper to launch a 51% assault on Bitcoin than on Ethereum.
Drake mentioned 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 complete PoS transition occasion). His remarks echo a Might 14 X post by Grant Hummer, the co-founder of Ethereum-focused advertising and product firm Etherealize.
Within the put up, Hummer mentioned that Bitcoin “is totally screwed due to its safety funds.”
Hummer claimed it could value $8 billion to run a profitable 51% assault, and he expects a profitable assault to be “nearly sure” when the fee slips to $2 billion. A 51% assault 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 develop into blindingly apparent over the following decade. ETH is the one really decentralized crypto-asset that may develop into the web’s [store of value].“

Ethereum assault would value way more
Drake defined that “to have 100% management of the chain, you want 50% + 1 of stake.” He mentioned that it could be extraordinarily tough and costly, however removed from unattainable:
“A wealthy nation state can in all probability pull it off.“
On 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.
Nonetheless, a a lot increased funding would doubtless 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 assault is price almost 14.2% of the market cap and 180% of the 24-hour buying and selling quantity. An enterprise of that dimension would doubtless trigger a big ETH value appreciation, additional rising the price of the assault.

Ethereum’s final line of protection
Matan Sitbon, the founder and CEO of blockchain interoperability developer Lightblocks, advised Cointelegraph that Ethereum has an extra function to defend towards 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 believes Ethereum has over Bitcoin. He defined that “if there’s a 51% assault, the social layer can establish the attacker and socially slash it.”
“It is a superpower of PoS that isn’t obtainable 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 less complicated proof-of-work (PoW) consensus mechanism has a smaller assault floor and longer reliability monitor file, nevertheless it lacks this function.
Pavel Yashin, Researcher at P2P.org, advised Cointelegraph that “if the centralization is detected,” the group may resolve it with a brand new fork. The outdated token would find yourself being delisted, and the compromised chain would fall into irrelevancy.
Hassan Khan, CEO at Bitcoin liquidity protocol Ordeez, advised Cointelegraph that “the controversy across the feasibility of a 51% assault stays open-ended — largely as a result of whereas theoretically attainable, in observe the boundaries are extraordinarily excessive.”
He mentioned that for Bitcoin, the mandatory quantity of computing energy and vitality “makes a sustained assault extremely unbelievable,” whereas for Ethereum, “PoS introduces extra financial and governance deterrents.”
