Functions

func CalculateScore added in v0.3.0 

func CalculateScore(baseTarget uint64) (*big.Int, error)

func IsNotFound added in v0.3.0 

func IsNotFound(err error) bool

func IsTxCommitmentError added in v0.8.0 

func IsTxCommitmentError(err error) bool

func ReadMainnetBlocksToHeight added in v0.5.0 

func ReadMainnetBlocksToHeight(height proto.Height) ([]*proto.Block, error)

This function is used for testing in other packages. This is more convenient, because blocks are stored in state's subdir.
