Yes, Beefy is working with Ankr to generate a snapshot for it before the hack. Beefy is a platform that provides snapshotting services for blockchain networks. This includes creating a snapshot of the state of the network at a certain point in time, which can then be used for a variety of purposes, such as restoring the network to a previous state or running analytics on the data. By creating a snapshot of the Ankr network before the hack, Beefy will be able to provide a comprehensive record of the network's state, which can be used to help identify the source of the hack and mitigate the damage.
