type DAGReader 

type DAGReader interface {
	// NextWord return next data chunk of the DAG dataset. First 8 bytes must
	// be ignored.
	NextWord() ([]byte, error)
}

DAGReader provides a way for smartpool to retrieve DAG dataset. How the DAG is retrieve is upto structs implementing the interface.

type NetworkClient 

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

func NewNetworkClient 

func NewNetworkClient(rpc RPCClient, workpool *WorkPool) *NetworkClient

func (nc *NetworkClient) SubmitSolution(s smartpool.Solution) bool

type RPCClient 

type RPCClient interface {
	ClientVersion() (string, error)
	GetWork() *Work
	SubmitHashrate(hashrate hexutil.Uint64, id common.Hash) bool

	SetExtradata(extradata string) error
}

type Share 

type Share struct {
	SolutionState int
	// contains filtered or unexported fields
}

func (*Share) BlockHeader 

func (s *Share) BlockHeader() *types.Header

func (*Share) Counter 

func (s *Share) Counter() *big.Int

We use concatenation of timestamp and nonce as share counter Nonce in ethereum is 8 bytes so counter = timestamp << 64 + nonce

func (s *Share) HashNoNonce() common.Hash

func (*Share) MixDigest 

func (s *Share) MixDigest() common.Hash

func (*Share) Nonce 

func (s *Share) Nonce() uint64

func (*Share) NonceBig 

func (s *Share) NonceBig() *big.Int

func (*Share) NumberU64 

func (s *Share) NumberU64() uint64

func (*Share) RlpHeaderWithoutNonce 

func (s *Share) RlpHeaderWithoutNonce() ([]byte, error)

	Hash      common.Hash
	MixDigest common.Hash
}

func (*Solution) WorkID 

func (s *Solution) WorkID() string

type TimestampClaimRepo added in v0.2.0 

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

TimestampClaimRepo only select shares that don't have most recent timestamp in order to make sure coming shares' counters are greater than selected shares

type Work 

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

Work represents Ethereum pow work

workpool keeps track of pending works to ensure that each submitted solution can actually be accepted by a real pow work. workpool also implements ShareReceiver interface.

func (WorkPool) AcceptSolution 

func (wp WorkPool) AcceptSolution(s smartpool.Solution) smartpool.Share

AcceptSolution takes solution and find corresponding work and return associated share. It returns nil if the work is not found.
