I am trying to write a private ethereum blockchain lab for both the college class I teach and a MeetUp group at the financial services firm where I work during the day. Using ethereum and geth on RPi 3B+. Can mining be performed on a Pi’s running Raspbian. I’ve been working with two date articles that don’t appear to be current with the geth and javascript console commands and options. Does anyone have any good pointers to an ethereum private blockchain on a raspberry pi for running smart contracts?
