The Bellatrix upgrade was the second scheduled upgrade for the Beacon Chain, preparing the chain for The Merge. It brings validator penalties to their full values for inactivity and slashable offenses. Bellatrix also includes an update to the fork choice rules to prepare the chain for The Merge and the transition from the last proof-of-work block to the first proof-of-stake block. This includes making consensus clients aware of the terminal total difficulty of 58750000000000000000000.
