5. def calcTreeWidth(leafCount: Int, height: Int): Int

7. def computeRoot(count: Int, height: Int, pos: Int, hashes: Seq[BinaryData], bits: List[Boolean], matched: List[(BinaryData, Int)]): (BinaryData, List[(BinaryData, Int)], Seq[BinaryData], List[Boolean])

   

   compute the root hash of a partial merkle tree: Read a bit from the flag bit list: If it is '0': Read a hash from the hashes list, and return it as this node's hash.

   compute the root hash of a partial merkle tree: Read a bit from the flag bit list: If it is '0': Read a hash from the hashes list, and return it as this node's hash. If it is '1' and this is a leaf node: Read a hash from the hashes list, store it as a matched txid, and return it as this node's hash. If it is '1' and this is an internal node: Descend into its left child tree, and store its computed hash as L. If this node has a right child as well: Descend into its right child, and store its computed hash as R. If L == R, the partial merkle tree object is invalid. Return Hash(L || R). If this node has no right child, return Hash(L || L).

   count

   total number of leaves

   height

   current height (0 == bottom of the tree == leaf nodes)

   pos

   current position at this height, 0 = first node from the left

   hashes

   remaining hashes to read from

   bits

   remaining flag bits to read from

   returns

   a (hash, matched, remaining_hashes, remaining_bits) tuple where:

   • hash is the hash at position (height, pos)
   • matched is a list of matched txids and their position in the original block
   • remaining_hashes and remaining_bits are hashes and bits that have not been used
