Virtual Box

In order to build a node from source, run it and connect it to the Cardano mainnet, you need a Linux system with at least 4GB RAM and 24GB hard drive space. The RAM is mostly needed for building the node; for running it, 1GB would be sufficient. The hard drive space is necessary if you want to connect to and download the Cardano blockchain.
