Types

type Backend

type Backend interface {
	BlockChain() *core.BlockChain
	TxPool() *core.TxPool
}

Backend wraps all methods required for mining.

type Config

type Config struct {
	Etherbase    common.Address `toml:",omitempty"` // Public address for block mining rewards (default = first account)
	Notify       []string       `toml:",omitempty"` // HTTP URL list to be notified of new work packages(only useful in ethash).
	ExtraData    hexutil.Bytes  `toml:",omitempty"` // Block extra data set by the miner
	GasFloor     uint64         // Target gas floor for mined blocks.
	GasCeil      uint64         // Target gas ceiling for mined blocks.
	GasPrice     *big.Int       // Minimum gas price for mining a transaction
	Recommit     time.Duration  // The time interval for miner to re-create mining work.
	Noverify     bool           // Disable remote mining solution verification(only useful in ethash).
	ManualMining bool
	ManualUncle  bool
	DisableUncle bool
}

Config is the configuration parameters of mining.

type Miner

type Miner struct {
	// contains filtered or unexported fields
