The post Charles Hoskinson Lauds Cardano Network’s Design After Surviving A “Poisoned” Transaction Attack ⋆ ZyCrypto appeared com. Charles Hoskinson was full of praise for the Cardano network’s full recovery after an unexpected attack caused a temporary chain split. The project’s engineers swiftly resolved the situation. Cardano Recovers After Chain Split The Cardano (ADA) blockchain suffered a rare chain split, which was caused by a malformed delegation transaction that exploited a software flaw. According to an incident report from Cardano ecosystem’s governance organization Intersect, the attack started after the malformed transaction passed validation on newer node versions, but nodes running older software rejected it. “This exploited a bug in an underlying software library that was not trapped by validation code,” Intersect said. “The execution of this transaction caused a divergence in the blockchain, effectively splitting the network into two distinct chains: one containing the ‘poisoned’ transaction and a ‘healthy’ chain without it.” Developers and engineers coordinated an emergency response, and operators were urged to upgrade nodes to version 10. 5. 3, essentially converging the network back to a single chain.

The FBI has been contacted to investigate the event as a potential cyberattack. “Cardano is a family, and sometimes we fight and sometimes we have bad days and good days. And it’s not lost on me how difficult 2025 has been for us all,” said Cardano founder Charles Hoskinson in a video message. “The network survived. It didn’t stop.” Attacker Issues Public Apology Shortly after the incident, an X user going by the name Homer.
