I'm quite interested in datacoin (I was an early miner of it back in 2013). But with the current difficulty I am interested in solo mining instead of pool mining. Graymines seem to take a very high percentage, or at least have bugs, since I mined over 1400 coins in a day and received only 200. Is there a windows software that I can use for solo GPU mine? (i doubt GPU mining would work with WSL).

It seems to me that this coin is very cool, but the main issue it's hitting is the software that's available. Thank you for fixing the wallet Graham, that was a big step forward. But in order to succeed it would need a lot more libraries for development (Node.JS, PHP, etc..), a lot more wallets. So that it's much easier to setup and run on servers. Projects would be born much faster if DTC had ways to quickly deploy on a web server, to create services, more trading platforms, etc...
I see that Primecoin has a primecoind release and that a lot of libraries use that. Can datacoin just run in command line and accepts an RPC connection? Or does it require a GUI? (just wondering if I can build a JS library and even an API for developers to use).

I think there is a huge potential for data storing on blockchain, even possibly storing data for entire social networks, it's just not that easy for developers to build with the low amount of libraries currently available.
