Such incidents see the chain unintentionally fork or duplicate. <\/p>\n<p>On this occasion, developers believe that the issue is due to circumstance rather than something serious such as a security issue or fundamental flaw, with a \u201cproposer boost fork\u201d being highlighted in particular. This term refers to a method in which specific proposers are given priority for selecting the next block in the blockchain. <\/p>\n<p>Core Ethereum developer Preston Van Loon suggested the reorg was due to a \u201cnon-trivial segmentation\u201d of new and old client node software, and was not necessarily anything malicious.
