Weekly Report #5 – 2017.08.07

City of Zion (CoZ) is a global community of open source enthusiasts, with the shared goal of helping NEO achieve its full potential. CoZ primarily operates through the community Slack and CoZ Github, central places where the community shares knowledge and contributes to projects.

CoZ is neither a corporation, nor a consulting firm or a devshop / for-hire group.

There is no formal process in joining CoZ. Interested individuals will have to do the work first, where the submitted code will have to be licensed under the MIT License. Consistent contributors will become eligible to join the CoZ organization, and begin collaborating on projects. The governance process of this organization can be found here.

Since its inception, CoZ has been in close contact with the NEO Core Team. The NEO Core Team provides support to the community in the form of NEO rewards, which CoZ redistributes weekly. This week, 951 NEO were awarded for following contributions to the NEO ecosystem:


We need experienced Stack Exchange users (with more than 200 reputation) that want to be active in our community, to commit to the proposal. You can do so here.
