              Functions

              func CreateConsensusEngine

              func CreateConsensusEngine(ctx *node.ServiceContext, config *ethash.Config, chainConfig *params.ChainConfig, db ethdb.Database) consensus.Engine

                CreateConsensusEngine creates the required type of consensus engine instance for an Ethereum service
