Types

type Agent added in v0.9.39

type Agent interface {
	Work() chan<- *Work
	SetReturnCh(chan<- *Result)
	Stop()
	Start()
	GetHashRate() int64
}

Agent can register themself with the worker

type Backend

type Backend interface {
	AccountManager() *accounts.Manager
	BlockChain() *core.BlockChain
	TxPool() *core.TxPool
	ChainDb() ethdb.Database
}

Backend wraps all methods required for mining.

type CpuAgent added in v0.9.39

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

func NewCpuAgent added in v0.9.39

func NewCpuAgent(chain consensus.ChainReader, engine consensus.Engine) *CpuAgent

func (*CpuAgent) GetHashRate added in v0.9.39

func (self *CpuAgent) GetHashRate() int64

func (*CpuAgent) SetReturnCh added in v0.9.39

func (self *CpuAgent) SetReturnCh(ch chan<- *Result)

func (*CpuAgent) Start added in v0.9.39

func (self *CpuAgent) Start()

func (*CpuAgent) Stop added in v0.9.39

func (self *CpuAgent) Stop()

func (*CpuAgent) Work added in v0.9.39

func (self *CpuAgent) Work() chan<- *Work

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 *params.ChainConfig, mux *event.TypeMux, engine consensus.Engine) *Miner

func (*Miner) HashRate

func (self *Miner) HashRate() (tot int64)

func (*Miner) Mining

func (self *Miner) Mining() bool

func (*Miner) Pending

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

Pending returns the currently pending block and associated state.

func (*Miner) PendingBlock

func (self *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) Register added in v0.9.39

func (self *Miner) Register(agent Agent)

func (*Miner) SetEtherbase

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

func (*Miner) SetExtra

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

func (*Miner) Start

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

func (*Miner) Stop

func (self *Miner) Stop()

func (*Miner) Unregister added in v1.3.1

func (self *Miner) Unregister(agent Agent)

type RemoteAgent added in v0.9.39

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

func NewRemoteAgent added in v0.9.39

func NewRemoteAgent(chain consensus.ChainReader, engine consensus.Engine) *RemoteAgent

func (*RemoteAgent) GetHashRate added in v0.9.39

func (a *RemoteAgent) GetHashRate() (tot int64)

GetHashRate returns the accumulated hashrate of all identifier combined

func (*RemoteAgent) GetWork added in v0.9.39

func (a *RemoteAgent) GetWork() ([3]string, error)

func (*RemoteAgent) SetReturnCh added in v0.9.39

func (a *RemoteAgent) SetReturnCh(returnCh chan<- *Result)

func (*RemoteAgent) Start added in v0.9.39

func (a *RemoteAgent) Start()

func (*RemoteAgent) Stop added in v0.9.39

func (a *RemoteAgent) Stop()

func (*RemoteAgent) SubmitHashrate added in v1.1.0

func (a *RemoteAgent) SubmitHashrate(id common.Hash, rate uint64)

func (*RemoteAgent) SubmitWork added in v0.9.39

func (a *RemoteAgent) SubmitWork(nonce types.BlockNonce, mixDigest, hash common.Hash) bool

SubmitWork tries to inject a pow solution into the remote agent, returning whether the solution was accepted or not (not can be both a bad pow as well as any other error, like no work pending).

func (*RemoteAgent) Work added in v0.9.39

func (a *RemoteAgent) Work() chan<- *Work

type Result added in v0.9.39

type Result struct {
	Work  *Work
	Block *types.Block
}

type Work added in v0.9.39

type Work struct {
	Block *types.Block // the new block
	// contains filtered or unexported fields
}

Work is the workers current environment and holds all of the current state information
