func New256() hash.Hash

New256 returns a new hash.Hash computing the BLAKE2b-256 checksum.

func Sum256(data []byte) [32]byte

Sum256 returns the BLAKE2b-256 checksum of the data.

func SumLeaf(leaf *[64]byte) [32]byte

SumLeaf computes the Merkle tree leaf hash of a single leaf.

func SumLeaves(outs *[4][32]byte, leaves *[4][64]byte)

SumLeaves computes the Merkle tree leaf hash of four leaves, storing the results in outs.

func SumNodes(outs *[4][32]byte, nodes *[8][32]byte)

SumNodes computes the Merkle roots of four pairs of node hashes, storing the results in outs.

func SumPair(left, right [32]byte) [32]byte

SumPair computes the Merkle root of a pair of node hashes.

type Accumulator struct {
	Trees     [64][32]byte
	NumLeaves uint64
}

An Accumulator is a generic Merkle tree accumulator.

func (acc *Accumulator) AddLeaf(h [32]byte)

AddLeaf incorporates a leaf into the accumulator.

func (acc *Accumulator) Root() [32]byte

Root returns the Merkle root of the accumulator's leaves.
