To contribute to BlockChain class and it’s working, you need to know:

• Rust Programming Language.
• Python Programming Language.
• pyo3 crate of rust.
• maturin library of python.

If the requirements are met, fork the repository, clone it and create a new branch:

git clone https://github.com/your-username-here/modstore.git
git checkout -b 'feature-name'

Make sure you add descriptive commit messages. To push them:

git push -u origin 'feature-name'

After that create a pull request and I will look into it.

Requirements to be installed:

Make sure you have python and rust installed.

pip install maturin

The files that you need to be concerned with:

• ‘src/blockchain.rs’ for changing internal blockchain working logic.
• ‘src/lib.rs’ for changing any module specific feature. This file incorporates both BlockChain and DAG inside a binary called _binaries.
• ‘pysrc/_binaries.pyi’ for defining any changed feature’s type declaration. Note that when the library is built using maturin, a binaries.so will be created. The binaries.pyi file is the static type declaration file for the same. The binaries.so file is os-dependent and therefore make sure you don’t push it to git. It is supposed to be built during wheel generation and is not needed as it is a bin file and not source code.
• ‘pysrc/rust/blockchain.py’ for adding the changes in the wrapper class that will be used by the user. This file contains a wrapper class so that the user does not have to interact with the rust binary directly. Instead the user deals with a safely designed structure.
