The Ethereum Beacon Chain network, a critical component for the blockchain network’s transition from PoW to PoS, experienced a seven-block reorganization. 

Ethereum Beacon Chain Crashed

The Beacon Chain, a new blockchain network of Ethereum 2.0, is the main link to transition from PoW to PoS. According to Beacon Scan, the test blockchain saw a seven-block reorganization on May 25. A reorganization, or reorg, replaces already existing blocks in the chain with new ones. Such a process can duplicate or deliberately branch the blockchain, which is a security issue. Experts believe that such actions could have been committed by a miner with a large resource, or there could have been a bug in the network.

Blockchain developer Martin Köppelmann discovered the error and shared the details on Twitter. He criticized the current “attestation strategy of nodes” and noted that the Ethereum network had not faced a reorganization of so many blocks in a long time.   

Blockchain network representatives responded to Köppelmann’s posts. Preston Van Loon, Ethereum Protocol Developer, believes that such a process results from “non-trivial segmentation” of new and old software. And Vitalik Buterin, the creator of the blockchain network, assured that the team is working to find the source of the error and eliminate the problem.

A full-fledged Ethereum blockchain merge with Beacon Chain is expected in Q2 2022. To recap, Ethereum Core Developer Tim Beiko recently asked app developers to check their readiness to switch to Ethereum 2.0. More than 8.5 million ETH are blocked on the Beacon Chain network for validator rights. These funds will be available only after the hard fork is launched.
