42 is the original 42-coin client and it builds the backbone of the network. It downloads and, by default, stores the entire history of 42-coin transactions, which requires a few hundred megabytes of disk space.

Depending on the speed of your computer and network connection, the synchronization process can take anywhere from a few minutes to a hour or more.

Development process

Developers work in their own trees, then submit pull requests when they think their feature or bug fix is ready.

The patch will be accepted if there is broad consensus that it is a good thing. Developers should expect to rework and resubmit patches if they don't match the project's coding conventions (see coding.txt) or are controversial.

The master branch is regularly built and tested, but is not guaranteed to be completely stable. Tags are regularly created to indicate new official, stable release versions of 42.

Feature branches are created when there are major new features being worked on by several people.

From time to time a pull request will become outdated. If this occurs, and the pull is no longer automatically mergeable; a comment on the pull will be used to issue a warning of closure. The pull will be closed 15 days after the warning if action is not taken by the author. Pull requests closed in this manner will have their corresponding issue labeled 'stagnant'.

Issues with no commits will be given a similar warning, and closed after 15 days from their last activity. Issues closed in this manner will be labeled 'stale'.
