The Ethereum (ETH) blockchain had a technical issue on May 12 that caused block completion to be interrupted for over an hour. The incident followed a previous technical problem on May 11, making it the second in 24 hours.
A bug could have attacked Ethereum
The Ethereum Beacon Chain was unable to complete transactions for an unclear reason, raising major security concerns for users. Steven Zheng, Block’s research director, mentioned that people speculate that the reason was errors in clients or MEV infrastructures.
The Ethereum Foundation stated that unfinished blocks could lead to the reordering or removal of pending transactions from the network.
The recent attack was the second in 24 hours, with the same issue on May 11 when finality stopped for about 25 minutes.
According to an Ethereum bets, they encountered a production incident where all four CL+EL sets deployed to their system were rebooted simultaneously, which is a rare phenomenon. It was then discovered that these Prysm BeaconNode suddenly doubled their memory usage, leading to memory limit and triggering OOM.
A self-proclaimed Ethereum Beacon Chain community health consultant, Superphiz.eth, clarified that transactions do not stop due to finality issues like Ethereum’s. In addition, he pointed out that the lack of finality had no impact on the activity in the chain.
As of this writing, the network has fixed the issue and restored the block completion.
The changes must be implemented on the network.
Some services built on Ethereum may need to modify operations due to finality issues. DYdX, for example, temporarily halted deposits due to the incident and continues to investigate and monitor the matter.
Superphiz.eth noted that it expects a third even with the second wave over. In addition, he advised validators on the network to increase their hardware specifications if they can and switch to a minority customer if possible. However, he pointed out that you shouldn’t worry too much about it, even if it looks terrible. The chain continues and will eventually end.
In the meantime, it is clear that doubts remain about the stability of Ethereum and could tarnish its credibility in the eyes of the builder. The reliability of a network is essential for blockchains that want to attract capital and grow users. That’s important because Ethereum is historically considered one of the most stable networks on the market.
