The Cosmos Hub blockchain experienced nearly 4 hours of interruption early in the morning and has now resumed block production

ChainCatcher message, Cosmos Hub stated on the X platform at 4:32 AM today that Cosmos Hub is experiencing a temporary chain interruption. Subsequently, in a follow-up post, it indicated that during the v17 upgrade, Hub validators patched a security vulnerability in the Liquid Staking Module (LSM).

After most validators implemented the patch for the vulnerability, 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 release a post-mortem analysis containing all the details as soon as possible.
