ZetaChain: An update rolled out to a minority of validators caused a consensus failure

On November 1, the ZetaChain status page was updated to say that the cause of the network outage had been identified, and that it was due to a consensus failure caused by an update rolled out to some validators. We believe that we have identified the root cause of the consensus failure, and will provide a more detailed root cause update after reproducing the problem on the development network. The top priority now is to restore the normal operation of the network. We have rolled back the managed validators to version v20.0.5 of the node software, and asked community members to do the same. Most members of the community have already completed this operation, and about 60% of validators are using the correct version of the software.
