Functions ¶
func Factory ¶
func Factory(ctx context.Context, config *consensus.Config, privateKey *ecdsa.PrivateKey, db storage.Storage, logger hclog.Logger) (consensus.Consensus, error)
Factory is the factory method to create an Ethash consensus
func FrontierDifficulty ¶
FrontierDifficulty is the difficulty calculation for the frontier fork
func HomesteadDifficulty ¶
HomesteadDifficulty is the difficulty calculation for the homestead fork
Types ¶
type Cache ¶
type Cache struct {
// contains filtered or unexported fields
}
Cache is a 16 MB pseudorandom cache.
type Ethash ¶
type Ethash struct {
// contains filtered or unexported fields
}
Ethash is the ethash consensus algorithm
func (*Ethash) CalcDifficulty ¶
CalcDifficulty calculates the difficulty at a given time.
func (*Ethash) Prepare ¶
Prepare initializes the consensus fields of a block header according to the rules of a particular engine. The changes are executed inline.
func (*Ethash) Seal ¶
func (e *Ethash) Seal(chain consensus.ChainReader, block *types.Block, ctx context.Context) (*types.Block, error)
Seal seals the block
func (*Ethash) SetDAOBlock ¶
SetDAOBlock sets the dao block, only to be used during tests
func (*Ethash) SetFakePow ¶
func (e *Ethash) SetFakePow()
SetFakePow sets the fakePow flag to true, only used on tests.
func (*Ethash) VerifyHeader ¶
func (e *Ethash) VerifyHeader(chain consensus.ChainReader, header *types.Header, uncle, seal bool) error
VerifyHeader verifies the header is correct
