ChainCatcher news, the liquid staking protocol Persistence tweeted that on November 6th, at block height 8647535, the Persistence Core-1 chain was interrupted for 4.5 hours. Currently, the Core-1 chain team and validators have resolved the issue and resumed block production.Regarding this downtime incident, Persistence stated that it was due to different versions of Golang used by the validators, leading to node uncertainty and a chain interruption. This event occurred after the v4 upgrade and was triggered by the staking epoch of the Epoch module. The LS module of pSTAKE is functioning normally and is unaffected; however, the ICA channel between Core-1 chain and CosmosHub has been closed. They are working with the pSTAKE team to rebuild the ICA channel and are proceeding with the v5 upgrade to launch pSTAKE on the Core-1 chain. (Source link)
