How would one get Ethereum to run on a raspberry pi zero?
The Raspberry Pi Zero might not have enough resources (memory/disk/cpu) to download the entire blockchain and be used as a full node. If you just want to use it for generating accounts (maybe as part of a cold wallet), you could:
Go to the go-ethereum v1.3.3 release page (or whatever is currently stable)
Download "geth-ARM-20160105140454-1.3.3-c541b38.tar.bz2" on your Raspberry Pi Zero
tar -xvf geth-ARM-20160105140454-1.3.3-c541b38.tar.bz2
gethas you would normally at the console. (
geth account newfor instance.)
If this doesn't work (I'm not sure on the compatibility between ARM architectures with various rPIs), you may need to custom compile it.
