Types

type Agent

type Agent interface {
	Work() chan<- *Work
	SetReturnCh(chan<- *Result)
	Stop()
	Start(ctx context.Context)
	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

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

func NewCpuAgent

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

func (*CpuAgent) GetHashRate

func (self *CpuAgent) GetHashRate() int64

func (*CpuAgent) SetReturnCh

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

func (*CpuAgent) Start

func (self *CpuAgent) Start(ctx context.Context)

func (*CpuAgent) Stop

func (self *CpuAgent) Stop()

func (*CpuAgent) Work

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(ctx context.Context, 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) PendingQuery

func (self *Miner) PendingQuery(fn func(*state.StateDB) error) error

PendingQuery calls fn with the pending (ready-only) state.

func (*Miner) Register

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(ctx context.Context, coinbase common.Address)

func (*Miner) Stop

func (self *Miner) Stop()

func (*Miner) Unregister

func (self *Miner) Unregister(agent Agent)

type RemoteAgent

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

func NewRemoteAgent

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

func (*RemoteAgent) GetHashRate

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

GetHashRate returns the accumulated hashrate of all identifier combined

func (*RemoteAgent) GetWork

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

func (*RemoteAgent) SetReturnCh

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

func (*RemoteAgent) Start

func (a *RemoteAgent) Start(ctx context.Context)

func (*RemoteAgent) Stop

func (a *RemoteAgent) Stop()

func (*RemoteAgent) SubmitHashrate

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

func (*RemoteAgent) SubmitWork

func (a *RemoteAgent) SubmitWork(ctx context.Context, 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

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

type Result

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

type Work

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
