CryptoNight mining is possible using a CPU-based mining program (such as
cpuminer-multi) on a Pi, and RasPiNews was able to set it up on a Pi 3.
cpuminer-multi does indeed support pools, as required, and can mine many cryptocurrencies, including Bytecoin.
You will need to build
cpuminer-multi yourself, using the instructions given in their README:
- ./autogen.sh # only needed if building from git repo
- ./nomacro.pl # only needed if building on Mac OS X or with Clang
- ./configure CFLAGS="-march=native"
- # Use -march=native if building for a single machine
However, it's unlikely to be terribly economical, and probably costs more in electricity, but it is possible to mine (slowly).
Surprisingly, though, one person reports that mining Monero (which also uses CryptoNight) is profitable with Raspberry Pi units running a CPU miner. Testing your hash rate and power consumption would evidently be wise in this case, as it might turn out to be modestly profitable, or might not.
