Ethereum Merge makes network more vulnerable to attack — Security expert

Despite the Ethereum Merge being touted as a major upgrade to the blockchain network, its transition to proof-of-stake theoretically makes it more vulnerable to exploit. Speaking to Cointelegraph, the security researcher explained that unlike proof-of-work (PoW) systems, a proof-of-stake (PoS) system informs node validators in advance what blocks they will validate, thus enabling them to plan attacks. The security expert, who asked not to be named, is a blockchain developer and security researcher working on a proof-of-stake layer-2 blockchain. The researcher explained that an exploit could theoretically occur on the post-Merge Ethereum blockchain if validators manage to line up two consecutive blocks to validate. “If you control two consecutive blocks, you can start an exploit on block N and finish it on block N+1 without having any arbitrage bot coming in and fixing the price that you have manipulated in between.” “From an economic security standpoint, [this vulnerability] makes these attacks relatively easier to pull off.”
