Functions

func GenerateResultApproval added in v0.26.1

func GenerateResultApproval(
	me module.Local,
	approvalHasher hash.Hasher,
	spockHasher hash.Hasher,
	attestation *flow.Attestation,
	spockSecret []byte,
) (*flow.ResultApproval, error)

GenerateResultApproval generates result approval for specific chunk of an execution receipt.

Types

type Engine

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

Engine (verifier engine) verifies chunks, generates result approvals or raises challenges. as input it accepts verifiable chunks (chunk + all data needed) and perform verification by constructing a partial trie, executing transactions and check the final state commitment and other chunk meta data (e.g. tx count)

func New

New creates and returns a new instance of a verifier engine.

func (*Engine) Done

func (e *Engine) Done() <-chan struct{}

Done returns a channel that is closed when the verifier engine is done.

func (*Engine) Process

func (e *Engine) Process(channel channels.Channel, originID flow.Identifier, event interface{}) error

Process processes the given event from the node with the given origin ID in a blocking manner. It returns the potential processing error when done.

func (*Engine) ProcessLocal

func (e *Engine) ProcessLocal(event interface{}) error

ProcessLocal processes an event originating on the local node.

func (*Engine) Ready

func (e *Engine) Ready() <-chan struct{}

Ready returns a channel that is closed when the verifier engine is ready.

func (*Engine) Submit

func (e *Engine) Submit(channel channels.Channel, originID flow.Identifier, event interface{})

Submit submits the given event from the node with the given origin ID for processing in a non-blocking manner. It returns instantly and logs a potential processing error internally when done.

func (*Engine) SubmitLocal

func (e *Engine) SubmitLocal(event interface{})

SubmitLocal submits an event originating on the local node.
