| The Beacon Chain network of the Ethereum 2.0 platform has undergone a reorganization to a depth of seven blocks.
“Unfortunately, this demonstrates that the analysis of Georgios Constantopoulos and Vitalik Buterin was overly optimistic when they argued in the paper that reorganizational stability would improve in Proof-of-Stake versus Proof-of-Work. We haven’t seen a seven block reorganization in Ethereum for many years,” wrote Gnosis co-founder Martin Koppelmann.
As a result of the May 25 incident, blocks #3,887,075 - #3,887,081 were reorganized.
According to developer Preston Van Loon, the team believes the failure was due to a "non-trivial segmentation" of new and old client software.
“We suspect this is due to the fact that the Proposer Boost fork was not fully implemented in the network,” he noted.
Ethereum co-founder Vitalik Buterin called it a “good hypothesis.”
Another lead developer, Terence Cao, confirmed that the reorganization was possible due to different timing of customer software updates. According to his calculations, about 75% of the nodes implemented Proposer Boost, and 25% did not.
“Such an incident had a 0.25% chance of occurring. So this is a big coincidence, ”the expert emphasized.
