[Cardano Experiences Temporary Chain Split on Friday Due to Old Code Vulnerability, CEO Says FBI Has Intervened in Investigation] November 23 news: Due to a 'malformed' delegation transaction, the Cardano network experienced a temporary chain split on Friday. This type of delegation transaction refers to transactions that delegate ADA to staking pools. While valid at the protocol level, such transactions may cause code failures, thereby affecting network functionality. According to an incident report released by Intersect, an organization within the Cardano ecosystem, the 'malformed' transaction exploited an old code vulnerability in the underlying software library of the Cardano blockchain. This caused discrepancies in how nodes processed the transaction, ultimately leading to the network split. The vulnerability was caused by an ADA staking pool operator named Homer J, who used AI-generated code to initiate the transaction and has admitted responsibility for causing the network split. Staking pool operators were instructed to download the latest version of the node software to fix the issue and merge the split chains back into a single, unified blockchain. This temporary split sparked debate within the Cardano community. Some argued that Homer J's actions helped expose critical vulnerabilities, while others, including Cardano founder Charles Hoskinson, described it as an attack on the Cardano network. The FBI has reportedly intervened in the investigation. Meanwhile, one user joked: 'No one noticed Cardano's network partition because no one uses it.'
