	# TODO: Implement the action on eosio contract to sync the active/inactive status of a specific block producer
	# into the EVM.
	#
	# Then call that action for each producer here, so all producers are synced.
	#
	# Then unregister a producer, sync it and check that the status is updated in the EVM.
