func HasFinality(update interfaces.LightClientUpdate) (bool, error)

func HasRelevantSyncCommittee ¶

func HasRelevantSyncCommittee(update interfaces.LightClientUpdate) (bool, error)

func IsBetterUpdate ¶

func IsBetterUpdate(newUpdate, oldUpdate interfaces.LightClientUpdate) (bool, error)

func NewLightClientBootstrapFromBeaconState ¶

func NewLightClientBootstrapFromBeaconState(
	ctx context.Context,
	currentSlot primitives.Slot,
	state state.BeaconState,
	block interfaces.ReadOnlySignedBeaconBlock,
) (interfaces.LightClientBootstrap, error)

func NewLightClientFinalityUpdateFromBeaconState ¶

func NewLightClientFinalityUpdateFromBeaconState(
	ctx context.Context,
	currentSlot primitives.Slot,
	state state.BeaconState,
	block interfaces.ReadOnlySignedBeaconBlock,
	attestedState state.BeaconState,
	attestedBlock interfaces.ReadOnlySignedBeaconBlock,
	finalizedBlock interfaces.ReadOnlySignedBeaconBlock,
) (interfaces.LightClientFinalityUpdate, error)

func NewLightClientOptimisticUpdateFromBeaconState ¶

func NewLightClientOptimisticUpdateFromBeaconState(
	ctx context.Context,
	currentSlot primitives.Slot,
	state state.BeaconState,
	block interfaces.ReadOnlySignedBeaconBlock,
	attestedState state.BeaconState,
	attestedBlock interfaces.ReadOnlySignedBeaconBlock,
) (interfaces.LightClientOptimisticUpdate, error)

func NewLightClientUpdateFromBeaconState ¶

func NewLightClientUpdateFromBeaconState(
	ctx context.Context,
	currentSlot primitives.Slot,
	state state.BeaconState,
	block interfaces.ReadOnlySignedBeaconBlock,
	attestedState state.BeaconState,
	attestedBlock interfaces.ReadOnlySignedBeaconBlock,
	finalizedBlock interfaces.ReadOnlySignedBeaconBlock) (interfaces.LightClientUpdate, error)

To form a LightClientUpdate, the following historical states and blocks are needed:

state: the post state of any block with a post-Altair parent block
block: the corresponding block
attested_state: the post state of attested_block
attested_block: the block referred to by block.parent_root
finalized_block: the block referred to by attested_state.finalized_checkpoint.root, if locally available (may be unavailable, e.g., when using checkpoint sync, or if it was pruned locally)
