.. _introduction:

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

From `The Dat Protocol`_: 

.. _The Dat Protocol: https://datprotocol.github.io/book/ch01-01-flat-tree.html

    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.

A note on naming
================

For the purposes of uniformity and easy of discovery alongside the reference
implementation, we use the same module name as `merkle-tree-stream`_. However,
there is currently no stream implemented, only a generator is available. This
is because the reference implementation of Hypercore 7 makes use of the
generator only. A `stream`_ implementation may follow.
