What are your thoughts on this topic. I was wondering what would be a better approach for mass adoption of the NKN project. - Original Topic
You can’t really make a medium size node cluster with Raspberrys unless you posses a class C block of IPv4 (For witch you need to be a bussiness and make a deal through a brokerage to buy a block, with the official documents up to date, a process that can took up to 3 weeks, and lastly convince your ISP to use your purchased ips).
So the option to go with would be VPS, I would recomment to use Vultr or DigitalOcean. As Vultr and Digital Ocean give you 100$ credit to use on VPS. Also Vultr have a limit of 100 VPS by default, so if you want a fast medium size deploy you can have it right in the instant you open the account. DigitalOcean in the other hand, has a limit of 10 VPS when you open the account, but you can ask for an expansion.
