Functions

func BlockLevel

func BlockLevel(header externalapi.BlockHeader, maxBlockLevel int) int

BlockLevel returns the block level of the given header.

func CheckProofOfWorkByBits

func CheckProofOfWorkByBits(header externalapi.MutableBlockHeader) bool

CheckProofOfWorkByBits check's if the block has a valid PoW according to its Bits field it does not check if the difficulty itself is valid or less than the maximum for the appropriate network

Types

type State

type State struct {
	Timestamp int64
	Nonce     uint64
	Target    big.Int
	// contains filtered or unexported fields
}

State is an intermediate data structure with pre-computed values to speed up mining.

func NewState

func NewState(header externalapi.MutableBlockHeader) *State

NewState creates a new state with pre-computed values to speed up mining It takes the target from the Bits field

func (*State) CalculateProofOfWorkValue

func (state *State) CalculateProofOfWorkValue() *big.Int

CalculateProofOfWorkValue hashes the internal header and returns its big.Int value

func (*State) CheckProofOfWork

func (state *State) CheckProofOfWork() bool

CheckProofOfWork check's if the block has a valid PoW according to the provided target it does not check if the difficulty itself is valid or less than the maximum for the appropriate network

func (*State) IncrementNonce

func (state *State) IncrementNonce()

IncrementNonce the nonce in State by 1
