func (*Engine) Address ¶

func (e *Engine) Address() common.Address

func (*Engine) Author ¶

func (e *Engine) Author(header *types.Header) (common.Address, error)

func (*Engine) CalcDifficulty ¶

func (e *Engine) CalcDifficulty(chain consensus.ChainHeaderReader, time uint64, parent *types.Header) *big.Int

func (*Engine) CommitHeader ¶

func (e *Engine) CommitHeader(header *types.Header, seals [][]byte, round *big.Int) error

func (*Engine) ExtractGenesisValidators ¶

func (e *Engine) ExtractGenesisValidators(header *types.Header) ([]common.Address, error)

func (*Engine) Finalize ¶

func (e *Engine) Finalize(chain consensus.ChainHeaderReader, header *types.Header, state *state.StateDB, txs []*types.Transaction, uncles []*types.Header)

Finalize runs any post-transaction state modifications (e.g. block rewards) and assembles the final block.

Note, the block header and state database might be updated to reflect any consensus rules that happen at finalization (e.g. block rewards).

func (*Engine) FinalizeAndAssemble ¶

func (e *Engine) FinalizeAndAssemble(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, ensuring no uncles are set, nor block rewards given, and returns the final block.

func (*Engine) Prepare ¶

func (e *Engine) Prepare(chain consensus.ChainHeaderReader, header *types.Header, validators istanbul.ValidatorSet) error

func (*Engine) ReadVote ¶

func (e *Engine) ReadVote(header *types.Header) (candidate common.Address, authorize bool, err error)

func (*Engine) Seal ¶

func (e *Engine) Seal(chain consensus.ChainHeaderReader, block *types.Block, validators istanbul.ValidatorSet) (*types.Block, error)

Seal generates a new block for the given input block with the local miner's seal place on top.

func (*Engine) SealHash ¶

func (e *Engine) SealHash(header *types.Header) common.Hash

func (*Engine) Signers ¶

func (e *Engine) Signers(header *types.Header) ([]common.Address, error)

func (*Engine) VerifyBlockProposal ¶

func (e *Engine) VerifyBlockProposal(chain consensus.ChainHeaderReader, block *types.Block, validators istanbul.ValidatorSet) (time.Duration, error)

func (*Engine) VerifyHeader ¶

func (e *Engine) VerifyHeader(chain consensus.ChainHeaderReader, header *types.Header, parents []*types.Header, validators istanbul.ValidatorSet) error

func (*Engine) VerifyHeaders ¶

func (e *Engine) VerifyHeaders(chain consensus.ChainHeaderReader, headers []*types.Header, seals []bool, validators istanbul.ValidatorSet) (chan<- struct{}, <-chan error)

func (*Engine) VerifySeal ¶

func (e *Engine) VerifySeal(chain consensus.ChainHeaderReader, header *types.Header, validators istanbul.ValidatorSet) error

VerifySeal checks whether the crypto seal on a header is valid according to the consensus rules of the given engine.

func (*Engine) VerifyUncles ¶

func (e *Engine) VerifyUncles(chain consensus.ChainReader, block *types.Block) error

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

func (*Engine) WriteVote ¶

func (e *Engine) WriteVote(header *types.Header, candidate common.Address, authorize bool) error
