Gulden is a revolutionary next generation blockchain based currency and payment system.
Gulden takes the blockchain concept to a whole new level; improving on multiple downsides and deficiencies in the earlier implementations of blockchain.

The project is driven at the core by a focus on key concepts like usability and quality which shows through in our software.

All code, binaries and other assets in this repository are subject to The Gulden license except where explicitely stated otherwise.


master branch tracks the current public release; is generally updated only for each release (with accompanying tag) and very occasionally for minor documentation or other commits. If all you want is to build/track the current version of the sofrware than use the master branch.

Each major version of the software gets its own branch e.g. 2.5_development, 2.4_development where if 2.5 were the next major release than both 2.5 and 2.4 may see some activity with 2.4 getting minor backports and updates while 2.5 development continues.

Major features are worked on in temporary feature branches until they can be merged back into one of the development branches. The currently most active branch, where most development that will go into the next major release is taking place is linked in the table at the top of this README as the dev branch and may be updated as development mandates seperate branches, for development changes you will generally want to work on this branch.


If you are thinking about contributing toward the development of Gulden in some capacity whether small or large, code or translating; Please read this guide first for information on how to do so.
