Types

type Backend

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

Backend wraps all methods required for mining.

type Config

type Config struct {
	Validator common.Address `toml:",omitempty"` // Public address for block signing and randomness (default = first account)
	ExtraData hexutil.Bytes  `toml:",omitempty"` // Block extra data set by the miner
}

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, db ethdb.Database) *Miner

func (*Miner) Close

func (miner *Miner) Close()

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) SetExtra

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

func (*Miner) SetTxFeeRecipient

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

SetTxFeeRecipient sets the address where the miner and worker will receive fees

func (*Miner) SetValidator

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

SetValidator sets the miner and worker's address for message and block signing

func (*Miner) Start

func (miner *Miner) Start(validator common.Address, txFeeRecipient common.Address)

func (*Miner) Stop

func (miner *Miner) Stop()

func (*Miner) SubscribePendingLogs

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

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