# merklecpp

A header-only C++ library for creation and manipulation of Merkle trees. It supports the usual

operations, like hash insertion, root computation, and path extraction, as well as some more

unusual features like flushing, retracting, and tree segment serialisation.

## Usage

    #include 

    merkle::Tree::Hash hash("fa8f44eabb728d4020e7f33d1aa973faaef19de6c06679bccdc5100a3c01f54a");

    merkle::Tree tree;

    tree.insert(hash);

    ...

    auto root = tree.root();

    auto path = tree.path(0);

    assert(path->verify(root));
