        "description": "# Modified Merkle Paticia Trie\n\nMPT is the data structure used in [Ethereum](https://www.ethereum.org/) as a cryptographically authenticated key-value data storage. \n\nThis library is a Python implementation of Modified Merkle Patrica Trie with a very simple interface.\n\n## Example\n\n```python\nstorage = {}\ntrie = MerklePatriciaTrie(storage)\n\ntrie.update(b'do', b'verb')\ntrie.update(b'dog', b'puppy')\ntrie.update(b'doge', b'coin')\ntrie.update(b'horse', b'stallion')\n\nold_root = trie.root()\nold_root_hash = trie.root_hash()\n\nprint(\"Root hash is {}\".format(old_root_hash.hex()))\n\ntrie.delete(b'doge')\n\nprint(\"New root hash is {}\".format(trie.root_hash().hex()))\n\ntrie_from_old_hash = MerklePatriciaTrie(storage, root=old_root)\n\nprint(trie_from_old_hash.get(b'doge'))\n\ntry:\n    print(trie.get(b'doge'))\nexcept KeyError:\n    print('Not accessible in a new trie.')\n```\n\n## Installing\n\nInstall and update using [pip](https://pip.pypa.io/en/stable/quickstart/):\n\n```\npip install -U eth_mpt\n```\n\n## Documentation\n\nDocumentation can be found on [readthedocs](https://merkle-patricia-trie.readthedocs.io/en/latest/).\n\n## Contributing\n\nAll the contributors are welcome. If you can make this library better, don't hesitate to :)\n\n## Testing\n\n```bash\npython -m unittest\n```\n\n\n",
