## Install

`pip3 install -U git+https://github.com/jjyr/mmr.py.git`

## Example

``` python 

from mmr import MMR

def test_mmr():

    def serialize(i):

        return i.to_bytes(4, 'little')

    mmr = MMR()

    # push 0..11 into MMR, and record MMR positions

    positions = [mmr.add(serialize(i)) for i in range(0, 11)]

    merkle_root = mmr.get_root()

    # proof

    elem = 5

    pos = positions[elem]

    # generate proof for 5

    proof = mmr.gen_proof(pos)

    # verify proof

    result = proof.verify(root=merkle_root, pos=pos,

                          elem=serialize(elem))

    assert(result)

    print("Ok")

test_mmr()

```
