- def build(hashes: Seq[DoubleSha256Digest]): MerkleTree
Builds a merkle tree from a sequence of hashes
- final def build(subTrees: Seq[MerkleTree], accum: Seq[MerkleTree]): MerkleTree
Builds a MerkleTree from sequence of sub merkle trees.
Builds a MerkleTree from sequence of sub merkle trees. This subTrees can be individual txids (leafs) or full blown subtrees
- subTrees
the trees that need to be hashed
- accum
the accumulated merkle trees, waiting to be hashed next round
- returns
the entire Merkle tree computed from the given merkle trees
