Functions

func ProcessBlock

func ProcessBlock(impl BlockProcessor, s abstract.BeaconState, block cltypes.GenericBeaconBlock) error

ProcessBlock processes a block with the block processor

func ProcessOperations

func ProcessOperations(impl BlockOperationProcessor, s abstract.BeaconState, blockBody cltypes.GenericBeaconBody) (signatures [][]byte, messages [][]byte, publicKeys [][]byte, err error)

ProcessOperations is called by ProcessBlock and prcesses the block body operations

func TransitionState

func TransitionState(impl Interface, s abstract.BeaconState, block *cltypes.SignedBeaconBlock) error

TransitionState will call impl..ProcessSlots, then impl.VerifyBlockSignature, then ProcessBlock, then impl.VerifyTransition
