Bitcoin Green is a sustainable cryptocurrency modeled after Satoshi Nakamoto’s vision for Bitcoin. It is a decentralized, peer-to-peer transactional currency designed to offer a solution to the problem posed by the exponential increase in energy consumed by Bitcoin and other proof-of-work currencies. Proof-of-work mining is environmentally unsustainable due to the electricity used by high-powered mining hardware. Bitcoin Green utilizes the Green Protocol, an energy efficient proof-of-stake algorithm inspired by peercoin, can be mined on any computer, and will never require specialized mining equipment. The Green Protocol offers a simple solution to Bitcoin sustainability issues and provides a faster, more scalable blockchain that is better suited for daily transactional use.

The master branch is regularly built and tested, but is not guaranteed to be completely stable.

The contribution workflow is described in CONTRIBUTING.md and useful hints for developers can be found in doc/developer-notes.md.

Testing and code review is the bottleneck for development; we get more pull requests than we can review and test on short notice. Please be patient and help out by testing other people's pull requests, and remember this is a security-critical project where any mistake might cost people lots of money.

Developers are strongly encouraged to write unit tests for new code, and to submit new unit tests for old code. Unit tests can be compiled and run (assuming they weren't disabled in configure) with: make check. Further details on running and extending unit tests can be found in /src/test/README.md.

There are also regression and integration tests, written in Python, that are run automatically on the build server. These tests can be run (if the test dependencies are installed) with: test/functional/test_runner.py

The Travis CI system makes sure that every pull request is built for Windows, Linux, and macOS, and that unit/sanity tests are run automatically.

Changes should be tested by somebody other than the developer who wrote the code. This is especially important for large or high-risk changes. It is useful to add a test plan to the pull request description if testing the changes is not straightforward.
