An app made to compute tasks from other nodes in the network using your CPU and you earn money for that.

How it works

This app works with webassembly files. These files are executed in a sandboxed environment (because uwp apps are sandboxed by default). You have the ability to execute a webassembly file on many nodes. To differentiate the node on which the webassembly file is executed, a numeric parameter is passed."

What's the story with WebAssembly and sockets/API calls?

I assume that WebAssembly prevents whatever it is running from opening sockets and making API calls...

If it doesn't -- then how will you prevent Black Hats / ill-intentioned people -- from creating Bot and DDoS networks, and other mayhem?
