Ethereum merge makes the network more vulnerable to attacks — security expert

Though the Ethereum merge is touted as a serious improve to the blockchain community, the transfer to proof-of-stake theoretically makes it extra susceptible to exploits.

Talking to Cointelegraph, the safety researcher defined that not like Proof-of-Work (PoW) programs, a Proof-of-Stake (PoS) system informs node validators upfront which blocks they are going to validate, thereby launching assaults can plan.

The safety professional, who needs to stay nameless, is a blockchain developer and safety researcher engaged on a Proof-of-Stake Layer 2 blockchain.

The researcher defined that theoretically there could possibly be an exploit on the post-merge Ethereum blockchain if the validators handle to string collectively two consecutive blocks for validation.

"Should you management two consecutive blocks, you can begin an exploit on block N and finish it on block N+1 with out an arbitrage bot coming in and fixing the value you manipulated in between."

“From the standpoint of financial safety [this vulnerability] makes these assaults comparatively simpler to carry out.”

The professional mentioned that whereas additionally it is attainable for miners to validate consecutive blocks in PoW networks, this quantities to "pure luck" and doesn't give the miner time to plan an assault.

Consequently, the safety researcher argues that Ethereum will sacrifice some safety power when the merger goes into impact:

"As we at the moment are [with] The Ethereum Proof-of-Work in comparison with the Ethereum Proof-of-Stake, the Ethereum Proof-of-Work has larger safety [...] and financial ensures.”

"However that is mentioned [...] Proof of Stake [still] has ample sensible safety [and] It would not matter that it isn't theoretically as safe as proof-of-work. It is nonetheless a really safe system," he added.

The safety professional added: “Ethereum is engaged on the repair [the consecutive block issue].

It is a powerful downside to resolve, however when that is finished, Proof-of-Stake safety will [further] improve [as] You might be shielded from these assault vectors.”

Ethereum validators will probably be trimmed in PoS because the consensus guidelines have been designed to offer validators an financial incentive to validate incoming transactions accurately and any conduct on the contrary would end result of their ETH stake being trimmed.

The Ethereum merge is lastly scheduled to happen round 2:30 UTC on September 15, according to to the Ethereum Merge Countdown by Blocknative. The transition to PoS goals to make the Ethereum community extra scalable and vitality environment friendly.
