Functions

func CreateMembershipProof

func CreateMembershipProof(tree *iavl.MutableTree, key []byte) (*ics23.CommitmentProof, error)

CreateMembershipProof will produce a CommitmentProof that the given key (and queries value) exists in the iavl tree. If the key doesn't exist in the tree, this will return an error.

func CreateNonMembershipProof

func CreateNonMembershipProof(tree *iavl.MutableTree, key []byte) (*ics23.CommitmentProof, error)

CreateNonMembershipProof will produce a CommitmentProof that the given key doesn't exist in the iavl tree. If the key exists in the tree, this will return an error.

func GetCommitmentProof

func GetCommitmentProof(proof *crypto.ProofOps, getMultiStoreEp bool) ([]byte, *ics23.ExistenceProof, *ics23.ExistenceProof, error)
