Are there any administrators here? How can I find out in which country the headquarters of this project is located? I can not find this information here.
You can take a look on the official project white papers which is available where you can view the complete information and the roadmap gives you a complete end to end vision with the infrastructure.
This I saw, and read completely the information on the road map. But I would like to know this information from an official source, for example, that would be answered by administrators, who unfortunately do not often write here.
