Functions ¶

func StateIndexFinalBlock ¶

func StateIndexFinalBlock(forkName string) uint64

func StateIndexNextSyncCommittee ¶

func StateIndexNextSyncCommittee(forkName string) uint64

func StateIndexSyncCommittee ¶

func StateIndexSyncCommittee(forkName string) uint64

Types ¶

type ChainConfig ¶

type ChainConfig struct {
	GenesisTime           uint64      // Unix timestamp of slot 0
	GenesisValidatorsRoot common.Hash // Root hash of the genesis validator set, used for signature domain calculation
	Forks                 Forks
	Checkpoint            common.Hash
	CheckpointFile        string
}

ChainConfig contains the beacon chain configuration.

func (*ChainConfig) AddFork ¶

func (c *ChainConfig) AddFork(name string, epoch uint64, version []byte) *ChainConfig

AddFork adds a new item to the list of forks.

func (*ChainConfig) ForkAtEpoch ¶

func (c *ChainConfig) ForkAtEpoch(epoch uint64) Fork

ForkAtEpoch returns the latest active fork at the given epoch.

func (*ChainConfig) LoadForks ¶

func (c *ChainConfig) LoadForks(file []byte) error

LoadForks parses the beacon chain configuration file (config.yaml) and extracts the list of forks.

func (*ChainConfig) SaveCheckpointToFile ¶

func (c *ChainConfig) SaveCheckpointToFile(checkpoint common.Hash) (bool, error)

SaveCheckpointToFile saves the given checkpoint to file if a checkpoint import/export file has been specified.

func (*ChainConfig) SetCheckpointFile ¶

func (c *ChainConfig) SetCheckpointFile(checkpointFile string) (bool, error)

SetCheckpointFile sets the checkpoint import/export file name and attempts to read the checkpoint from the file if it already exists. It returns true if a checkpoint has been loaded.

type ClientConfig ¶

type ClientConfig struct {
	ChainConfig
	Apis         []string
	CustomHeader map[string]string
	Threshold    int
	NoFilter     bool
}

ClientConfig contains beacon light client configuration.

type Fork ¶

type Fork struct {
	// Name of the fork in the chain config (config.yaml) file
	Name string

	// Epoch when given fork version is activated
	Epoch uint64

	// Fork version, see https://github.com/ethereum/consensus-specs/blob/dev/specs/phase0/beacon-chain.md#custom-types
	Version []byte
	// contains filtered or unexported fields
}

Fork describes a single beacon chain fork and also stores the calculated signature domain used after this fork.

type Forks ¶

type Forks []*Fork

Forks is the list of all beacon chain forks in the chain configuration.

func (Forks) Len ¶

func (f Forks) Len() int

func (Forks) Less ¶

func (f Forks) Less(i, j int) bool

func (Forks) SigningRoot ¶

func (f Forks) SigningRoot(epoch uint64, root common.Hash) (common.Hash, error)

SigningRoot calculates the signing root of the given header.

func (Forks) Swap ¶

func (f Forks) Swap(i, j int)
