Functions

func CalcDifficulty 

func CalcDifficulty(chain consensus.ChainReader, config *params.ChainConfig, 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.

Types

type API 

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

API exposes ethash related methods for the RPC interface.

func (*API) GetHashrate 

func (api *API) GetHashrate() uint64

GetHashrate returns the current hashrate for local CPU miner and remote miner.

func (*API) GetWork 

func (api *API) GetWork() ([5]string, error)

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
result[3] - hex encoded block number

func (*API) SubmitHashRate 

func (api *API) SubmitHashRate(rate hexutil.Uint64, id common.Hash) bool

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 

func (api *API) SubmitWork(hash common.Hash, nonce, plotter, number uint64) [2]string

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 {
	PocMode Mode
}

Config are the configuration parameters of the ethPoc.

type EthPoc 

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

EthPoc is a consensus engine based on proof-of-Capacity implementing the ethpoc algorithm.

func New 

func New(chainConfig *params.ChainConfig, am *accounts.Manager, config Config, notify []string, noverify bool) *EthPoc

New creates a full sized ethPoc 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) *EthPoc

NewFakeDelayer creates a ethPoc 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 Ethereum consensus rules.

func NewFakeFailer 

func NewFakeFailer(fail uint64) *EthPoc

NewFakeFailer creates a ethPoc 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 Ethereum consensus rules.

func NewFaker 

func NewFaker() *EthPoc

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

func NewFullFaker 

func NewFullFaker() *EthPoc

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

func NewTester 

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

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

func (*EthPoc) APIs 

func (ethPoc *EthPoc) APIs(chain consensus.ChainReader) []rpc.API

APIs implements consensus.Engine, returning the user facing RPC APIs.

func (*EthPoc) Author 

func (ethPoc *EthPoc) Author(header *types.Header) (common.Address, error)

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

func (*EthPoc) CalcDifficulty 

func (ethPoc *EthPoc) CalcDifficulty(chain consensus.ChainReader, 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 (*EthPoc) Close 

func (ethPoc *EthPoc) Close() error

Close closes the exit channel to notify all backend threads exiting.

func (*EthPoc) Finalize 

func (ethPoc *EthPoc) Finalize(chain consensus.ChainReader, header *types.Header, state *state.StateDB, txs []*types.Transaction, uncles []*types.Header)

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

func (*EthPoc) FinalizeAndAssemble 

func (ethPoc *EthPoc) FinalizeAndAssemble(chain consensus.ChainReader, 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 (*EthPoc) Prepare 

func (ethPoc *EthPoc) Prepare(chain consensus.ChainReader, header *types.Header) error

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

func (*EthPoc) Seal 

func (ethPoc *EthPoc) Seal(chain consensus.ChainReader, block *types.Block, results chan<- *types.Block, stop <-chan struct{}) error

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

func (*EthPoc) SealHash 

func (ethPoc *EthPoc) SealHash(header *types.Header) (hash common.Hash)

SealHash returns the hash of a block prior to it being sealed.

func (*EthPoc) SetBlockChain 

func (ethPoc *EthPoc) SetBlockChain(blockChain *core.BlockChain)

func (*EthPoc) SetThreads 

func (ethPoc *EthPoc) SetThreads(threads int)

func (*EthPoc) VerifyHeader 

func (ethPoc *EthPoc) VerifyHeader(chain consensus.ChainReader, header *types.Header, seal bool) error

VerifyHeader checks whether a header conforms to the consensus rules of the stock Ethereum EthPoc engine.

func (*EthPoc) VerifyHeaders 

func (ethPoc *EthPoc) VerifyHeaders(chain consensus.ChainReader, 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 (*EthPoc) VerifySeal 

func (ethPoc *EthPoc) VerifySeal(chain consensus.ChainReader, header *types.Header) error

VerifySeal implements consensus.Engine, checking whether the given block satisfies the PoW difficulty requirements.

func (*EthPoc) VerifyUncles 

func (ethPoc *EthPoc) VerifyUncles(chain consensus.ChainReader, block *types.Block) error

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

type Mode uint
const (
	ModeNormal Mode = iota
	ModeShared
	ModeTest
	ModeFake
	ModeFullFake
