One of the reasons I joined the live peer community was as a traditional cryptocurrency miner Live peer has the ability to run in parallel with traditional Proof-of-Work (PoW) with minimal impact to each service.
I think the obvious choice for PoW + Live Peer is Eth as the fees required to make reward calls are presented in eth. The basis for my research is the following paper:
What we can tell you is that we have experienced in stability in the configuration to the point of the hardware platform requiring a complete hard power down and restart. Lets us present the hardware components, versions of software, added/modified configuration files.
Triple AMD Radeon Sapphire RX470 8GB - Stock Firmware
1000w EVGA power supply
Built on a custom open airframe
OS: Ubuntu 18.04.2 LTS
Live Peer: v0.3.3
Mining Software: Ethminer 0.17.1
As part of our optimization we limit the max power draw of the GPUs and spin the fans faster than the factory setting to keep heat at a reasonable level ( < 60c )

Mining Command Line
#!/bin/bash ./ethminer --tstop 60 --tstart 50 --farm-recheck 200 --HWMON 1 -R -G stratum://0x71d832098Ae580c25733d20429Ac58E1960551c5.email@example.com:4444
This configuration is currently running @ 74Mh/s
We have seen issues with system stability. We believe it’s due to the mining software or the mining software in conjunction with LP. When the system runs LP solo we have not seen any issues.
One we see these errors the system becomes close to non-responsive. The time to get into this state is around 3 weeks.
The next step is to cycle the mining software on given intervals to give the operating system a chance perform garbage collection and perform a reset of system resources. This will be performed with a combination of timeout and cron.
