Proof of Working

4 min readDec 22, 2017

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 Discord 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.

Governance

There is no formal process in joining CoZ. Interested individuals will have to do the work first, and the submitted code has 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.

Funding

Since its inception, the CoZ Council has been in close contact with the NEO Council. The NEO Council provides support to the community, in the form of NEO rewards, which CoZ redistributes weekly.

For individuals who are interested in financially supporting CoZ development, our donation address is AXSoNQEKjmqPBNPg5cNrHyWivfjok3Vj9D.

For transparency, CoZ Council members are excluded from weekly NEO rewards, and any CoZ competitions. This week, 319 NEO were awarded for the contributions to the NEO ecosystem.

Week in Review

Announcement

The security research company Red4Sec just concluded a 3 months audit on NEO reference code. Given the success of this endeavor I’m glad to announce that Red4Sec researchers Shargon and Belane will be joining CoZ full time for at least 6 months on the project neo-sharp (formerly NEO2, a rewrite of NEO core) and on continued security review of current code bases. CoZ will write a article about neo-sharp on its medium magazine Proof of Working in near future.

dApp Competition:

Registration for the second CoZ dApp competition opens on 25 January 2018! Learn more on the official website.

Campaigns

Stack Exchange:

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.

Development Updates

Contributions lately been so big and done by so many contributors that we are not able to track and publish a report every week, because of that we are changing the format of our reports to a more technical description done together with the CoZ contributors.
