ArcBlock is NOT an open source platform, nor it is an open source project. We develop ArcBlock as a commercial software development practices and process. We will open source several critical protocols and their references implementations at the point we reach certain milestones.
Even though ArcBlock is not an open source project, ArcBlock is built with open standards. We’re trying our best not to reinvent the wheel and to build for the application developer’s wants and needs. In addition to open sourcing our core components, we will also actively contribute to a variety of blockchain technology communities.
