1func EmptyRoot() [32]byte

source

EmptyRoot is keccak256(rlp("")), the root of an empty Ethereum MPT.

1func Verify(root []byte, key []byte, value []byte, proof [][]byte) error

source

Verify verifies an Ethereum Merkle Patricia Trie existence proof. Thin wrapper around verifyProof: go-ethereum has no combined verify+compare function of its own (callers compare inline at each VerifyProof call site).

1func VerifyAbsence(root []byte, key []byte, proof [][]byte) error

source

VerifyAbsence verifies that key is absent from the trie under root. Thin wrapper around verifyProof (see Verify).
