We had exactly the same needs, and without any opensource solution on the web, we decided to make it ourself. So we start working on a zec proxy this week and we made a nice alpha version (made from scratch, nodeJS, working with EWBF, tested on flypool with several rigs ).
We have now to fix some stuff and add some robustness hacks to allow “production usage” but we’re pretty close to a sherable version. I think we’ll be able to share an initial version next week.
We are also thinking about/adding some other cool features like pool failover system, cool Ascii UI, watchdog system (alerts/miners auto reboot on stuck GPUs), hashrate monitoring, pm2 support, etc… Lot of cool stuff to do
The project will be released on GitHub in Open Source & will be dev-fee free; however donations will be highly appreciated
Keep in touch
