I decided to go a little deeper into the project and briefly understand the main goals of Hacash. The founder was and disappeared, but someone continues to support the project repository on github and the site. It is supposed to use Hacash by analogy with Bitcoin (as a means of payment), but I do not see any solutions to this issue. Hacash is not traded on cryptocurrency exchanges, there are no trading platforms that accept it as a means of payment. So far, only mining is working from the entire project. Who has any thoughts on this?
Someone uses a full node and mines diamonds?
I've mined full node, pool and diamond. What questions did you have in that regards?
In regards to your other question: You're absolutely right. It is a project with a "good idea" and functioning mining, but the UI for the solutions it promises are yet to be developed (channel chain settlement, tx privacy options, the BTC "Black Hole") as far as I can tell. Developing such tools is beyond my own knowledge so I can't really comment as to the state of the code for such tools.
