Functions

func VerifyProof

func VerifyProof(root Digest, index int, value []byte, proof []Digest) (valid bool, more bool)

VerifyProof verifies that the given value maps to the given index in the merkle-tree with the given root. It returns "more" if the value is not the last value in the merkle-tree.

Types

type Digest

type Digest = [32]byte

Digest is a 32-byte hash digest.

func Tree

func Tree(values [][]byte) Digest

Tree returns a the root of the merkle-tree of the given values.

func TreeWithProofs

func TreeWithProofs(values [][]byte) (Digest, [][]Digest)

TreeWithProofs returns a the root of the merkle-tree of the given values, along with merkle-proofs for each leaf.
