Why can't we use a normal computer?
Why there is no Windows version?
The standard for Skywire miners is to use a cluster of ARM boards because this gives better security and efficiency. That being said, Skywire supports Linux and MacOS, and there are instructions for installation available for those platforms as well.

There is currently no official support for Windows, but you might want to try following this guide.

Running a Skywire node will allow you to run the node client app which lets you test out the vpn function of Skywire, connecting to the internet from all over the world.
Since we are still in the testnet phase, there is no whitelisting planned for nonstandard Skywire nodes, so don't expect to gain mining rewards. During the mainnet, any Skywire nodes would be able to receive mining rewards, but serious participants will be using a standard Skyminer setup with ARM boards, either DIY or Official.
Please have a look at the Official Skywire announcement and visit our telegram.
