Its 2019 and your Raspberry Pi is sitting in the corner. You haven’t used it much since your last project and you are ready to do more with it. Why not mine a CPU only or low difficulty coin? Sure you won’t get rich, but you’ll have some crypto to trade around and learn about compiling miners and how to use exchanges and how to use mining pools. The Pi also uses a very small amount of power.
Allow me to introduce to MagiCoin at https://www.m-core.org/
Magi coin uses a POW/POS system but with a bit of a twist. As they put it “MAGI concentrates on global energy savings when maintaining its blockchain system. MAGI aims at worldwide mining based on, for example, mobile devices. MAGI’s PoW with difficulty dependent mining rewards applies a limit to the total network hashrate, where huge amount of computational power for mining is no longer necessary”
This makes it the perfect target for mining with that old Raspberry Pi you just have lying around.
To get started install Ubuntu or Debian or Raspbian on your Raspberry Pi 2 or 3 and connect to it via ssh.
To begin make sure you have the latest software
sudo apt-get update
sudo apt-get upgrade
Next we need some deps to complete the compile of the Magicoin Miner
sudo apt-get install automake autoconf pkg-config libcurl4-openssl-dev libjansson-dev libssl-dev libgmp-dev make g++ git libgmp-dev screen
Lets make a directory so we know where the miner is to be located
Then clone the Github Repo
git clone https://github.com/magi-project/m-cpuminer-v2.git
Now we just need to compile the miner to get to hashing.
./autogen.sh && ./configure CFLAGS="-O3" CXXFLAGS="-O3" && make
Now that you’re mining away, check out this cooling fan kit we sell to help keep those temps down. Get 5% off with code “hashrate”
This might take a while but when it is done you’ll be ready to earn some Magicoin.
The next step is to find a pool, personally I use https://pom.m-hash.com/ They have a limit of 250K/hs so its great for slow miners
The next step is to start a screen session so that even after we disconnect from SSH the Pi continues mining.
Now its time to hash away! To start mining
./m-minerd -o POOL_URL:PORT -u USERNAME.WORKER -p PASSWORD
To detach from the screen session after verifying its mining,
hit ctr+a d
To reconnect, use
Magi is also POS so if you set up the official wallet you can begin staking coins, if you mine enough, or buy a few extra. If you just want to sell or buy Magicoin you can do that here.
