Functions

func ComputeCompactValue

func ComputeCompactValue(path []byte, payload *ledger.Payload, nodeHeight int) []byte

ComputeCompactValue computes the value for the node considering the sub tree to only include this value and default values.

func GetDefaultHashForHeight

func GetDefaultHashForHeight(height int) []byte

GetDefaultHashForHeight returns the default hashes of the SMT at a specified height.

For each tree level N, there is a default hash equal to the chained hashing of the default value N times.

func GetDefaultHashes

func GetDefaultHashes() [257][]byte

GetDefaultHashes returns the default hashes of the SMT.

For each tree level N, there is a default hash equal to the chained hashing of the default value N times.

func HashInterNode

func HashInterNode(hash1 []byte, hash2 []byte) []byte

HashInterNode generates hash value for intermediate nodes (SHA3-256).

func HashLeaf

func HashLeaf(path []byte, value []byte) []byte

HashLeaf generates hash value for leaf nodes (SHA3-256).

func VerifyTrieBatchProof

func VerifyTrieBatchProof(bp *ledger.TrieBatchProof, expectedState ledger.State) bool

VerifyTrieBatchProof verifies all the proof inside the batchproof

func VerifyTrieProof

func VerifyTrieProof(p *ledger.TrieProof, expectedState ledger.State) bool

VerifyTrieProof verifies the proof, by constructing all the hash from the leaf to the root and comparing the rootHash
