ChainCatcher reported that according to The Block, the block browser showed that the Cosmos-based Layer1 blockchain Canto was interrupted after the "​​Callisto" upgrade on Saturday UTC time, causing the main network to be paralyzed at about 18:43 UTC time (02:43 Beijing time on August 11). Since the interruption, the blockchain has been unable to process new transactions.

On Sunday afternoon, Canto’s X account acknowledged the outage and attributed the downtime to a “consensus issue.” Canto said an upgrade designed to fix the problem will take place at 12:00 UTC on August 12 (20:00 Beijing time on August 12), and assured users that their funds are safe.
