Functions

func BeaconNodeOptions

func BeaconNodeOptions(c *cli.Context) (node.Option, error)

BeaconNodeOptions is responsible for determining if the checkpoint sync options have been used, and if so, reading the block and state ssz-serialized values from the filesystem locations specified and preparing a checkpoint.Initializer, which uses the provided io.ReadClosers to initialize the beacon node database.
