Functions

func Register

func Register(stack *node.Node, backend *les.LightEthereum) error

Register adds catalyst APIs to the light client.

Types

type ConsensusAPI

type ConsensusAPI struct {
	// contains filtered or unexported fields
}

func NewConsensusAPI

func NewConsensusAPI(les *les.LightEthereum) *ConsensusAPI

NewConsensusAPI creates a new consensus api for the given backend. The underlying blockchain needs to have a valid terminal total difficulty set.

func (*ConsensusAPI) ExchangeTransitionConfigurationV1

func (api *ConsensusAPI) ExchangeTransitionConfigurationV1(config engine.TransitionConfigurationV1) (*engine.TransitionConfigurationV1, error)

ExchangeTransitionConfigurationV1 checks the given configuration against the configuration of the node.

func (*ConsensusAPI) ExecutePayloadV1

func (api *ConsensusAPI) ExecutePayloadV1(params engine.ExecutableData) (engine.PayloadStatusV1, error)

ExecutePayloadV1 creates an Eth1 block, inserts it in the chain, and returns the status of the chain.

func (*ConsensusAPI) ForkchoiceUpdatedV1

func (api *ConsensusAPI) ForkchoiceUpdatedV1(heads engine.ForkchoiceStateV1, payloadAttributes *engine.PayloadAttributes) (engine.ForkChoiceResponse, error)

ForkchoiceUpdatedV1 has several responsibilities:

We try to set our blockchain to the headBlock.

If the method is called with an empty head block: we return success, which can be used to check if the catalyst mode is enabled.

If the total difficulty was not reached: we return INVALID.

If the finalizedBlockHash is set: we check if we have the finalizedBlockHash in our db, if not we start a sync.

If there are payloadAttributes: we return an error since block creation is not supported in les mode.

func (*ConsensusAPI) GetPayloadV1

func (api *ConsensusAPI) GetPayloadV1(payloadID engine.PayloadID) (*engine.ExecutableData, error)

GetPayloadV1 returns a cached payload by id. It's not supported in les mode.
