Despite the Ethereum Merge being linked 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
