ethereum-merkle-patricia-trie 0.0.3

In order to understand Ethereum's core functionalities, I am implementing parts of it for myself. Here I am implementing the Merkle Patricia Trie (MPT) purely in Python 3.

Install

pip install ethereum-merkle-patricia-trie

Requirements

In order to use the package, you need to install LevelDb on your system.

Tests

In order to run the tests, execute the following command:

$ python -m unittest

Usage

Here an example on how to use the package:

from mpt.trie import Trie

t = Trie('./testdb')
t.update(b'abcd', b'hello world')

print(t.get_value(b'abcd'))

print(t.get_root_hash())

t.delete(b'abcd')

Upload to Pypi

Uploading and testing using test Pypi

python -m build
python -m twine upload --repository testpypi dist/*
pip install --index-url https://test.pypi.org/simple/ --no-deps merklePatriciaTrie

Uploading to Pypi

python -m build
python -m twine upload dist/*

Contributions

python3 -m virtualenv --python /path/to/python3 venv
source ./venv/bin/activate
pip install -r requirements.txt

Install the pre-commit hooks using the following command:
