ETH 2.0 PySpec
The Python executable spec is built from the ETH 2.0 specification, complemented with the necessary helper functions for hashing, BLS, and more.
With this executable spec, test-generators can easily create test-vectors for client implementations, and the spec itself can be verified to be consistent and coherent, through sanity tests implemented with pytest.
Building
All the dynamic parts of the spec can be build at once with make pyspec.
Alternatively, you can build a sub-set of the pyspec: make phase0.
Or, to build a single file, specify the path, e.g. make test_libs/pyspec/eth2spec/phase0/spec.py
Contributing
Contributions are welcome, but consider implementing your idea as part of the spec itself first.
The pyspec is not a replacement.
If you see opportunity to include any of the pyspec/eth2spec/utils/ code in the spec,
please submit an issue or PR.
License
Same as the spec itself, see LICENSE file in spec repository root.
