Types

type MerkleProof

type MerkleProof struct {

	// RootHash root of the Merkle tree
	RootHash frontend.Variable

	// Path path of the Merkle proof
	Path []frontend.Variable
}

MerkleProof stores the path, the root hash and an helper for the Merkle proof.

func (*MerkleProof) VerifyProof

func (mp *MerkleProof) VerifyProof(api frontend.API, h hash.Hash, leaf frontend.Variable)

VerifyProof takes a Merkle root, a proofSet, and a proofIndex and returns true if the first element of the proof set is a leaf of data in the Merkle root. False is returned if the proof set or Merkle root is nil, and if 'numLeaves' equals 0.
