[Cardano Experiences Temporary Chain Split on Friday Due to Old Code Vulnerability, CEO Says FBI Has Intervened in Investigation] According to Cointelegraph, the Cardano network experienced a temporary chain split on Friday due to a 'malformed' delegation transaction. Such delegation transactions refer to transactions that delegate ADA to staking pools. While valid at the protocol level, they may cause code malfunctions, thereby affecting network functionality. An incident report released by Intersect, an organization within the Cardano ecosystem, stated that 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 execute the transaction and has admitted responsibility for 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.'
