func HashSliceToBytes(hashes []common.Hash) []byte

HashSliceToBytes serializes a []common.Hash into a tightly packed byte array.

func IncrOne added in v0.3.0

func IncrOne(bytes []byte)

IncrOne increments bytes value by one

func IsForkTransition

func IsForkTransition(fork *big.Int, parent *big.Int, current *big.Int) bool

IsForkTransition returns true if [fork] activates during the transition from [parent] to [current]. Note: this works for both block number and timestamp activated forks.

func IsForked

func IsForked(s, head *big.Int) bool
