Quebecoin Core integration/staging tree

Build Status

What is Quebecoin?

Quebecoin is an experimental digital currency that enables instant payments to anyone, anywhere in the world. Quebecoin uses peer-to-peer technology to operate with no central authority: managing transactions and issuing money are carried out collectively by the network. Quebecoin Core is the name of open source software which enables the use of this currency.

For more information, as well as an immediately usable, binary version of the Quebecoin Core software, see, or read the original Bitcoin whitepaper.

Quebecoin is distinct from Bitcoin in that it pioneered the use of multiple independent PoW algorithms on the same chain.


Quebecoin is a fork of Bitcoin Core and inherits the terms of the MIT license. See COPYING for more information or see

Development Process

The master branch is occasionally built and tested, but is not guaranteed to be completely stable. Tags are created regularly to indicate new official, stable release versions of Quebecoin Core.

The contribution workflow is described in

The developer subreddit should be used to discuss complicated or controversial changes before working on a patch set.

Developer IRC can be found on Freenode at ##quebecoin.


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.

Automated Testing

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/

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/

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

Manual Quality Assurance (QA) Testing

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.


Changes to translations as well as new translations are typically handled upstream, see bitcoin github.

Translators should also visit the quebecoin subreddit.
