Functions

func Check

func Check(e error)

checks an error if not nil, it breaks the execution

func CompareCommitment

func CompareCommitment(u *Commitment, v *Commitment) bool

CompareCommitment compares two commitments

func DecodeAccount

func DecodeAccount(accStr string) (*PublicKey, *Commitment, error)

DecodeAccount returns the Pk and Commitment reconstructed from hex

func DecodePoints

func DecodePoints(bytes []byte) (*r255.Element, *r255.Element)

DecodePoints returns the underlying Ristretto Points reconstructed from the concatenated byte array

func NewMsgServerImpl

func NewMsgServerImpl(keeper Keeper) types.MsgServer

NewMsgServerImpl returns an implementation of the MsgServer interface for the provided Keeper.

func ScalarFromBytes

func ScalarFromBytes(b [32]byte) (*r255.Scalar, error)
