Cardano experienced a brief chain split on Friday due to an old code vulnerability. The vulnerability was caused by a staking pool operator named Homer J, who used AI-generated code to drive a delegation transaction. Nodes diverged in transaction processing, resulting in a network split. The issue was resolved when the staking pool operator downloaded the latest node software and reintegrated the split chain into a single blockchain. The incident has sparked a debate within the Cardano community, with some calling it a critical flaw exposure and others labeling it an attack on the network.
