Functions ¶
func CalcDifficulty ¶
CalcDifficulty is the difficulty adjustment algorithm. It returns the difficulty that a new block should have when created at time given the parent block's time and difficulty.
func DeleteTester ¶
func DeleteTester()
Types ¶
type API ¶
type API struct {
// contains filtered or unexported fields
}
API exposes cuckoo related methods for the RPC interface.
func (*API) GetHashrate ¶
GetHashrate returns the current hashrate for local CPU miner and remote miner.
func (*API) GetWork ¶
GetWork returns a work package for external miner.
The work package consists of 3 strings:
result[0] - 32 bytes hex encoded current block header pow-hash result[1] - 32 bytes hex encoded seed hash used for DAG result[2] - 32 bytes hex encoded boundary condition ("target"), 2^256/difficulty
func (*API) SubmitHashRate ¶
SubmitHashrate can be used for remote miners to submit their hash rate. This enables the node to report the combined hash rate of all miners which submit work through this node.
It accepts the miner hash rate and an identifier which must be unique between nodes.
func (*API) SubmitWork ¶
SubmitWork can be used by external miner to submit their POW solution. It returns an indication if the work was accepted. Note either an invalid solution, a stale work a non-existent work will return false.
type Config ¶
type Config struct { CacheDir string CachesInMem int CachesOnDisk int DatasetDir string DatasetsInMem int DatasetsOnDisk int PowMode Mode UseCuda bool //UseOpenCL bool StrDeviceIds string Threads int Algorithm string Mine bool }
compatiable with cuckoo interface
type Cuckoo ¶
type Cuckoo struct {
// contains filtered or unexported fields
}
func NewFakeDelayer ¶ added in v1.0.0
func NewFakeFailer ¶ added in v1.0.0
func NewFullFaker ¶
func NewFullFaker() *Cuckoo
func (*Cuckoo) Author ¶
Author implements consensus.Engine, returning the header's coinbase as the proof-of-work verified author of the block.
func (*Cuckoo) CalcDifficulty ¶
func (cuckoo *Cuckoo) CalcDifficulty(chain consensus.ChainHeaderReader, time uint64, parent *types.Header) *big.Int
CalcDifficulty is the difficulty adjustment algorithm. It returns the difficulty that a new block should have when created at time given the parent block's time and difficulty.
func (*Cuckoo) CuckooVerifyHeader ¶ added in v1.0.0
func (*Cuckoo) Finalize ¶
func (cuckoo *Cuckoo) Finalize(chain consensus.ChainHeaderReader, header *types.Header, state *state.StateDB, txs []*types.Transaction, uncles []*types.Header) error
Finalize implements consensus.Engine, accumulating the block and uncle rewards, setting the final state on the header
func (*Cuckoo) FinalizeAndAssemble ¶ added in v1.10.14
func (cuckoo *Cuckoo) FinalizeAndAssemble(chain consensus.ChainHeaderReader, header *types.Header, state *state.StateDB, txs []*types.Transaction, uncles []*types.Header, receipts []*types.Receipt) (*types.Block, error)
Finalize implements consensus.Engine, accumulating the block and uncle rewards, setting the final state and assembling the block.
func (*Cuckoo) FinalizeWithoutParent ¶ added in v1.10.3
func (cuckoo *Cuckoo) FinalizeWithoutParent(chain consensus.ChainHeaderReader, header *types.Header, state *state.StateDB, txs []*types.Transaction, uncles []*types.Header, receipts []*types.Receipt) (*types.Block, error)
FinalizeAndAssemble implements consensus.Engine, accumulating the block and uncle rewards, setting the final state and assembling the block.
func (*Cuckoo) Prepare ¶
Prepare implements consensus.Engine, initializing the difficulty field of a header to conform to the cuckoo protocol. The changes are done inline.

func (*Cuckoo) VerifyHeaders ¶
func (cuckoo *Cuckoo) VerifyHeaders(chain consensus.ChainHeaderReader, headers []*types.Header, seals []bool) (chan<- struct{}, <-chan error)
VerifyHeaders is similar to VerifyHeader, but verifies a batch of headers concurrently. The method returns a quit channel to abort the operations and a results channel to retrieve the async verifications.
func (*Cuckoo) VerifySeal ¶
func (*Cuckoo) VerifySolution ¶
