Ethereum’s transition to the «green» blockchain will make the cryptocurrency more vulnerable to hacker attacks

A security expert, who preferred to remain anonymous, has named one of the main problems with the transition of Ethereum to the «green» blockchain — The Merge risks increasing the number of cryptocurrency fraudsters and hackers. This became known from the publication of the Cointelegraph, whose journalists talked to the anonymous expert and confirmed the reliability of his statements.

According to the security expert, PoS is less secure than PoW, so the expected update will make the Ethereum blockchain more vulnerable to various cyberattacks. Unlike PoW, the green blockchain informs node validators in advance which blocks will be verified, thus allowing hackers to plan attacks.

It is worth noting that Ethereum developers are aware of the theoretically possible security problems and are already working on solving them. «This problem is difficult to solve, but if it is done, the security of proof-of-stake will be at a high level, as Ethereum will be protected from various attack vectors,» the security expert emphasized.

As for the Ethereum update, it will take place on September 15 at 02:17:03. A few days ago, Ethereum developers confirmed the successful fulfillment of the prerequisites — the quality of the shadow forks required for the long-awaited blockchain update, which is called The Merge. The test network allowed Ethereum developers to practice launching nodes, deploying contracts, and testing infrastructure. As part of the upgrade, the community needs to update its Ethereum nodes, which is currently facing some problems — the community is not keeping up with the developers' actions.
