Ethereum Merge architect Justin Drake instructed Cointelegraph that he believes it might be cheaper to launch a 51% assault on Bitcoin than on Ethereum.
Drake stated it might be “less expensive to 51% assault Bitcoin” and that it might 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 Could 14 X submit by Grant Hummer, the co-founder of Ethereum-focused advertising and marketing and product firm Etherealize.
Within the submit, Hummer stated that Bitcoin “is totally screwed due to its safety finances.”
Hummer claimed it might value $8 billion to run a profitable 51% assault, and he expects a profitable assault to be “just about 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:
“It will turn into blindingly apparent over the subsequent decade. ETH is the one really decentralized crypto-asset that may turn into the web’s [store of value].“

Ethereum assault would value far more
Drake defined that “to have 100% management of the chain, you want 50% + 1 of stake.” He stated that it might be extraordinarily troublesome and costly, however removed from unimaginable:
“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 greater 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 endeavor of that measurement would doubtless trigger a major ETH worth appreciation, additional growing the price of the assault.

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 locally’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% assault, the social layer can determine 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, that 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 observe report, nevertheless it lacks this function.
Pavel Yashin, Researcher at P2P.org, instructed 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, instructed 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 obstacles are extraordinarily excessive.”
He stated that for Bitcoin, the mandatory quantity of computing energy and power “makes a sustained assault extremely inconceivable,” whereas for Ethereum, “PoS introduces further financial and governance deterrents.”
