Project description


Build Status

A stream that generates a merkle tree based on the incoming data

A hash tree or merkle tree is a tree in which every leaf node is labelled with the hash of a data block and every non-leaf node is labelled with the cryptographic hash of the labels of its child nodes. Merkle trees in Dat are specialized flat trees that contain the content of the archives.


$ pip install merkle-tree-stream


import hashlib

def _leaf(node, roots=None):
    return hashlib.sha256(

def _parent(first, second):
    sha256 = hashlib.sha256()
    return sha256.digest()

merkle = MerkleTreeGenerator(leaf=leaf, parent=parent)


assert len(merkle) == 2 + 1
