A rough arch design for a Nano streaming service. I saw that other thread about Nano streaming with paywalls at a browser plugin level. This idea is a bit more focused to live stream only with a lightweight frontend website.
For the payment processor it could probably leverage the IFTTT tool for Nano. Every viewer session would have to have a unique payment though for tracking. I wouldn't want to do the new receiving account for every purchase approach.
For a proof of concept a single Ngnix docker could be used but it could only support around 500 client connections.
