type Engine 

type Engine interface {
	EngineReader
	EngineWriter
}

Engine is an algorithm agnostic consensus engine.

type EngineReader 

type EngineReader interface {
	// Author retrieves the Ethereum address of the account that minted the given
	// block, which may be different from the header's coinbase if a consensus
	// engine is based on signatures.

	//
	// Note, the method returns immediately and will send the result async. More
	// than one result may also be returned depending on the consensus algorithm.
	Seal(chain ChainHeaderReader, block *types.BlockWithReceipts, results chan<- *types.BlockWithReceipts, stop <-chan struct{}) error

	// SealHash returns the hash of a block prior to it being sealed.
