Functions

func Register

func Register(stack *node.Node, backend *eth.Ethereum) error

Register adds the engine API to the full node.

Types

type ConsensusAPI

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

func NewConsensusAPI

func NewConsensusAPI(eth *eth.Ethereum) *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 beacon.TransitionConfigurationV1) (*beacon.TransitionConfigurationV1, error)

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

func (*ConsensusAPI) ForkchoiceUpdatedV1

func (api *ConsensusAPI) ForkchoiceUpdatedV1(update beacon.ForkchoiceStateV1, payloadAttributes *beacon.PayloadAttributesV1) (beacon.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 engine API 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 try to assemble a block with the payloadAttributes and return its payloadID.

func (*ConsensusAPI) GetPayloadV1

func (api *ConsensusAPI) GetPayloadV1(payloadID beacon.PayloadID) (*beacon.ExecutableDataV1, error)

GetPayloadV1 returns a cached payload by id.

func (*ConsensusAPI) NewPayloadV1

func (api *ConsensusAPI) NewPayloadV1(params beacon.ExecutableDataV1) (beacon.PayloadStatusV1, error)

NewPayloadV1 creates an Eth1 block, inserts it in the chain, and returns the status of the chain.
