The Beacon Chain network of Ethereum 2.0 has experienced a reorganization to a depth of seven blocks.
Martin Koppelmann, co-founder of Ethereum-based prediction market platform Gnosis, has said:
“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.”
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 that the failure was due to a “non-trivial segmentation” of new and old client software.
