Py-EVM is a new implementation of the Ethereum Virtual Machine written in python. It is currently in active development but is quickly progressing through the test suite provided by ethereum/tests. I have Vitalik, and the existing PyEthereum code to thank for the quick progress I’ve made as many design decisions were inspired, or even directly ported from the PyEthereum codebase.
Py-EVM aims to eventually become the defacto python implementation of the EVM, enabling a wide array of use cases for both public and private chains. Development will focus on creating an EVM with a well defined API, friendly and easy to digest documentation which can be run as a fully functional mainnet node.
The plan is to begin with an MVP, alpha-level release that is suitable for testing purposes. We’ll be looking for early adopters to provide feedback on our architecture and API choices as well as general feedback and bug finding.
pip install -e . -r requirements-dev.txt
You can run the tests with:
py.test tests
Or you can install tox
to run the full test suite.
Pandoc is required for transforming the markdown README to the proper format to render correctly on pypi.
For Debian-like systems:
apt install pandoc
Or on OSX:
brew install pandoc
To release a new version:
bumpversion $$VERSION_PART_TO_BUMP$$
git push && git push --tags
make release
The version format for this repo is {major}.{minor}.{patch}
for stable, and
{major}.{minor}.{patch}-{stage}.{devnum}
for unstable (stage
can be alpha or beta).
To issue the next version in line, use bumpversion and specify which part to bump,
like bumpversion minor
or bumpversion devnum
.
If you are in a beta version, bumpversion stage
will switch to a stable.
To issue an unstable version when the current version is stable, specify the
new version explicitly, like bumpversion --new-version 4.0.0-alpha.1 devnum
