Cosmos Hub announced on X platform at 4:32 this morning that it is experiencing a temporary chain interruption. In subsequent posts, it stated that during the v17 upgrade, Hub validators patched a security vulnerability in the Liquid Staking Module (LSM). After most validators implemented this patch, Cosmos Hub stated a few minutes ago that the previous issue has been resolved and Cosmos Hub is generating blocks again. Informal Systems and Hypha Cosmos will soon release post-mortem analyses containing all details.
