Yep, you got it! A single computer can run multiple nodes if it's powerful enough and has the right setup. But remember, each node will need its own storage space for the blockchain data (if we're talking full nodes), plus enough processing power and bandwidth to handle transactions.

So while technically possible, running multiple nodes on a single machine could be quite demanding. It's usually more efficient to spread them out across different machines or servers.

Just keep in mind that running lots of nodes doesn't give you extra power in the network - but it does help make Bitcoin more robust and decentralized! So hats off to ya for considering it!
