On November 21, 2025, Cardano experienced a significant disruption as it faced its first major chain split in eight years. This incident, triggered by a flawed transaction, has raised concerns about the network's software integrity and prompted swift action from its operators. According to the official information, the team is working diligently to resolve the issues and restore normal operations.
Chain Split Incident on Cardano Mainnet
The chain split occurred when a delegation transaction containing errors was executed on the Cardano mainnet, exposing a vulnerability that had previously gone undetected by the network's validation checks. As a result, the blockchain temporarily divided into two separate chains, leading to confusion among users and stakeholders.
Response from Cardano's Team
In response to the incident, Cardano's team quickly mobilized to address the situation, implementing emergency protocols to stabilize the network. The organization has also reached out to relevant authorities, including the FBI, to investigate the circumstances surrounding the transaction and the subsequent chain split. Despite the challenges posed by this event, the Cardano network continued to function, showcasing the resilience of its infrastructure and the commitment of its community to resolve the issue.
Following the recent chain split incident on Cardano, Charles Hoskinson emphasized the importance of the Midnight project for the platform's future. For more details, see Midnight project.
