Types

type Blake3pow 

type Blake3pow struct {
	// contains filtered or unexported fields
}

Blake3pow is a proof-of-work consensus engine using the blake3 hash algorithm

func New 

func New(config Config, notify []string, noverify bool, logger *log.Logger) *Blake3pow

New creates a full sized blake3pow PoW scheme and starts a background thread for remote mining, also optionally notifying a batch of remote services of new work packages.

func NewFakeDelayer 

func NewFakeDelayer(delay time.Duration) *Blake3pow

NewFakeDelayer creates a blake3pow consensus engine with a fake PoW scheme that accepts all blocks as valid, but delays verifications by some time, though they still have to conform to the Quai consensus rules.

func NewFakeFailer 

func NewFakeFailer(fail uint64) *Blake3pow

NewFakeFailer creates a blake3pow consensus engine with a fake PoW scheme that accepts all blocks as valid apart from the single one specified, though they still have to conform to the Quai consensus rules.

func NewFaker 

func NewFaker() *Blake3pow

NewFaker creates a blake3pow consensus engine with a fake PoW scheme that accepts all blocks' seal as valid, though they still have to conform to the Quai consensus rules.

func NewFullFaker 

func NewFullFaker() *Blake3pow

NewFullFaker creates an blake3pow consensus engine with a full fake scheme that accepts all blocks as valid, without checking any consensus rules whatsoever.

func NewShared 

func NewShared() *Blake3pow

NewShared creates a full sized blake3pow PoW shared between all requesters running in the same process.

func NewTester 

func NewTester(notify []string, noverify bool) *Blake3pow

NewTester creates a small sized blake3pow PoW scheme useful only for testing purposes.

func (blake3pow *Blake3pow) Author(header *types.WorkObject) (common.Address, error)

Author implements consensus.Engine, returning the header's coinbase as the proof-of-work verified author of the block.

func (*Blake3pow) CalcDifficulty 

func (blake3pow *Blake3pow) CalcDifficulty(chain consensus.ChainHeaderReader, parent *types.WorkObjectHeader, expansionNum uint8) *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 (*Blake3pow) CalcOrder 

func (blake3pow *Blake3pow) CalcOrder(header *types.WorkObject) (*big.Int, int, error)

CalcOrder returns the order of the block within the hierarchy of chains

func (*Blake3pow) CalcRank added in v0.29.0 

func (blake3pow *Blake3pow) CalcRank(chain consensus.GenesisReader, header *types.WorkObject) (int, error)

CalcRank returns the rank of the block within the hierarchy of chains, this determines the level of the interlink

func (*Blake3pow) CheckIfValidWorkShare added in v0.29.0 

func (blake3pow *Blake3pow) CheckIfValidWorkShare(workShare *types.WorkObjectHeader) bool

func (blake3pow *Blake3pow) ComputePowLight(header *types.WorkObjectHeader) (common.Hash, common.Hash)

func (*Blake3pow) DeltaLogS 

func (blake3pow *Blake3pow) DeltaLogS(chain consensus.GenesisReader, header *types.WorkObject) *big.Int

func (*Blake3pow) Finalize 

func (blake3pow *Blake3pow) Finalize(chain consensus.ChainHeaderReader, header *types.WorkObject, state *state.StateDB)

Finalize implements consensus.Engine, accumulating the block and uncle rewards, setting the final state on the header

func (*Blake3pow) FinalizeAndAssemble 

func (blake3pow *Blake3pow) FinalizeAndAssemble(chain consensus.ChainHeaderReader, header *types.WorkObject, state *state.StateDB, txs []*types.Transaction, uncles []*types.WorkObjectHeader, etxs []*types.Transaction, subManifest types.BlockManifest, receipts []*types.Receipt) (*types.WorkObject, error)

FinalizeAndAssemble implements consensus.Engine, accumulating the block and uncle rewards, setting the final state and assembling the block.

func (*Blake3pow) IntrinsicLogS 

func (blake3pow *Blake3pow) IntrinsicLogS(powHash common.Hash) *big.Int

IntrinsicLogS returns the logarithm of the intrinsic entropy reduction of a PoW hash

func (*Blake3pow) IsDomCoincident 

func (blake3pow *Blake3pow) IsDomCoincident(chain consensus.ChainHeaderReader, header *types.WorkObject) bool

func (*Blake3pow) NodeLocation added in v0.29.0 

func (blake3pow *Blake3pow) NodeLocation() common.Location

NodeLocation returns the location of the node

func (*Blake3pow) Prepare 

func (blake3pow *Blake3pow) Prepare(chain consensus.ChainHeaderReader, header *types.WorkObject, parent *types.WorkObject) error

Prepare implements consensus.Engine, initializing the difficulty field of a header to conform to the blake3pow protocol. The changes are done inline.

func (*Blake3pow) Seal 

func (blake3pow *Blake3pow) Seal(header *types.WorkObject, results chan<- *types.WorkObject, stop <-chan struct{}) error

Seal implements consensus.Engine, attempting to find a nonce that satisfies the header's difficulty requirements.

func (*Blake3pow) SetThreads 

func (blake3pow *Blake3pow) SetThreads(threads int)

SetThreads updates the number of mining threads currently enabled. Calling this method does not start mining, only sets the thread count. If zero is specified, the miner will use all cores of the machine. Setting a thread count below zero is allowed and will cause the miner to idle, without any work being done.

func (*Blake3pow) Threads 

func (blake3pow *Blake3pow) Threads() int

Threads returns the number of mining threads currently enabled. This doesn't necessarily mean that mining is running!

func (*Blake3pow) TotalLogPhS

VerifyHeader checks whether a header conforms to the consensus rules of the stock Quai blake3pow engine.

func (*Blake3pow) VerifyHeaders 

func (blake3pow *Blake3pow) VerifyHeaders(chain consensus.ChainHeaderReader, headers []*types.WorkObject) (chan<- struct{}, <-chan error)

func (blake3pow *Blake3pow) VerifySeal(header *types.WorkObjectHeader) (common.Hash, error)

VerifySeal returns the PowHash and the verifySeal output

func (*Blake3pow) VerifyUncles 

func (blake3pow *Blake3pow) VerifyUncles(chain consensus.ChainReader, block *types.WorkObject) error

VerifyUncles verifies that the given block's uncles conform to the consensus rules of the stock Quai blake3pow engine.
