Development Process

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

Developers work on their own forks and submit pull requests in order to merge changes with master. Due to the relatively small size of the development team, developers also commit directly to the repo often. Anyone is allowed to contribute though and useful pull requests will almost always be accepted given various obvious stipulations regarding stability etc.

The Fujicoin slack or subreddit should be used to discuss complicated or controversial changes with the developers before working on a patch set.


Fujicoin currently relies on Bitcoin Core for its testcases, and few of them are known to work, though the software is based on fully test conforming upstream Bitcoin Core versions. We would be grateful to those who can help port the existing Bitcoin Core test cases to Fujicoin such that they can be used to assure correctness.


Changes to translations as well as new translations can be submitted to Fujicoin Core's Transifex page.

Translations are periodically pulled from Transifex and merged into the git repository. See the translation process for details on how this works.

Important: We do not accept translation changes as GitHub pull requests because the next pull from Transifex would automatically overwrite them again.

Translators should also subscribe to the mailing list.
