sealed trait PartialMerkleTree extends AnyRef

Created by chris on 8/7/16. Represents a subset of known txids inside of a Block in a way that allows recovery of the txids & merkle root without having to store them all explicitly. See BIP37 for more details

Encoding procedure: "Bitcoin.org: creating a merkleblock message" "Bitcoin Core: merkleblock.cpp" Traverse the tree in depth first order, storing a bit for each traversal. This bit signifies if the node is a parent of at least one matched leaf txid (or a matched leaf txid) itself. In case we are the leaf level, or this bit is 0, it's merkle node hash is stored and it's children are not explored any further. Otherwise no hash is stored, but we recurse all of this node's child branches.

Decoding procedure: "Bitcoin.org: parsing a merkleblock message" "Bitcoin Core: merkleblock.cpp" The same depth first decoding procedure is performed, but we consume the bits and hashes that we used during encoding
