Functions ¶

func BuildSha254Memtree ¶

func BuildSha254Memtree(rawIn io.Reader, size abi.UnpaddedPieceSize) ([]byte, error)

BuildSha254Memtree builds a sha256 memtree from the input data Returned slice should be released to the pool after use

func ComputeBinShaParent ¶

func ComputeBinShaParent(left, right [NODE_SIZE]byte) [NODE_SIZE]byte

func NodeLevel ¶

func NodeLevel(leaves, arity int64) int

Types ¶

type RawMerkleProof ¶

type RawMerkleProof struct {
	Leaf  [32]byte
	Proof [][32]byte
	Root  [32]byte
}

func MemtreeProof ¶

func MemtreeProof(memtree []byte, leafIndex int64) (*RawMerkleProof, error)

MemtreeProof generates a Merkle proof for the given leaf index from the memtree. The memtree is a byte slice containing all the nodes of the Merkle tree, including leaves and internal nodes.
