The first thing you will note is that the Bit Coin Core software will advise you it needs 100GB to download the blockchain. I bought a machine specifically for some new experiments including bitcoin and some other things.\
What Is A Full Node?
Bitcoin Core implements a full node. A full node is a program that fully validates transactions and blocks. Almost all full nodes also help the network by accepting transactions and blocks from other full nodes, validating those transactions and blocks, and then relaying them to further full nodes.
