func ComputeForkDigest ¶

func ComputeForkDigest(version phase0.Version, genesisValidatorsRoot phase0.Root) ([4]byte, error)

ComputeForkDigest returns the fork for the current version and genesis validator root

Spec pseudocode definition:

	def compute_fork_digest(current_version: Version, genesis_validators_root: Root) -> ForkDigest:
   """
   Return the 4-byte fork digest for the ``current_version`` and ``genesis_validators_root``.
   This is a digest primarily used for domain separation on the p2p layer.
   4-bytes suffices for practical separation of forks/chains.
   """
   return ForkDigest(compute_fork_data_root(current_version, genesis_validators_root)[:4])
