Cardano founder Charles Hoskinson has acknowledged the inevitability of zero-day vulnerabilities and chain outages in blockchain systems, including Cardano. Speaking on a podcast, Hoskinson discussed a recent chain split on November 21 that revealed a long-standing vulnerability. He highlighted the complexity of blockchain software, which makes code flaws unavoidable, but commended Cardano's engineering team for their swift response. The chain split temporarily divided the network into 'contaminated' and 'healthy' segments, though no downtime occurred. Major exchanges paused ADA deposits and withdrawals as a precaution. Despite the incident, ADA's price has rebounded, climbing 2.4% to $0.43.
