Variables

var (
	// ErrCannotCommitTxn signals that the transaction execution failed
	// when attempting to mine a transaction.
	//
	// NOTE: This error is not expected to occur in regular operation of
	// l2geth, rather the actual execution error should be returned to the
	// user.
	ErrCannotCommitTxn = errors.New("Cannot commit transaction in miner")
)

Types

type Backend

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

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).
}

Config is the configuration parameters of mining.

type Miner

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

Miner creates blocks and searches for proof-of-work values.

func New

func New(eth Backend, config *Config, chainConfig *params.ChainConfig, mux *event.TypeMux, engine consensus.Engine, isLocalBlock func(block *types.Block) bool) *Miner

func (*Miner) Close

func (miner *Miner) Close()

func (*Miner) HashRate

func (miner *Miner) HashRate() uint64

func (*Miner) Mining

func (miner *Miner) Mining() bool

func (*Miner) Pending

func (miner *Miner) Pending() (*types.Block, *state.StateDB)

Pending returns the currently pending block and associated state.

func (*Miner) PendingBlock

func (miner *Miner) PendingBlock() *types.Block

PendingBlock returns the currently pending block.

Note, to access both the pending block and the pending state simultaneously, please use Pending(), as the pending state can change between multiple method calls

func (*Miner) SetEtherbase

func (miner *Miner) SetEtherbase(addr common.Address)

func (*Miner) SetExtra

func (miner *Miner) SetExtra(extra []byte) error

func (*Miner) SetRecommitInterval

func (miner *Miner) SetRecommitInterval(interval time.Duration)

SetRecommitInterval sets the interval for sealing work resubmitting.

func (*Miner) Start

func (miner *Miner) Start(coinbase common.Address)

func (*Miner) Stop

func (miner *Miner) Stop()

func (*Miner) SubscribePendingLogs

func (self *Miner) SubscribePendingLogs(ch chan<- []*types.Log) event.Subscription

SubscribePendingLogs starts delivering logs from pending transactions to the given channel.
