# Commercio.network nodes
Commercio.network blockchain has two different nodes types: full nodes and validator nodes.
Inside this page you will learn the difference between them, which role they play inside the whole blockchain, and how you can create either one of them.
If you have questions or comments, please create an issue (opens new window). This is a community guide any contribute is important! Please help us to improve by opening an issue (opens new window).
# Full nodes
Full nodes are nodes that simply store the whole transactions history. To do so, they connect to the blockchain and each time a new transaction is made, they write it on the hard disk. This means that being a full node you will be able to read the whole chain transaction from its beginning, but you will need to have a large store space if you want to keep it running for a long period of time.
Become a full node
If you are interested in becoming a full node, you can read the full node installation guide
# Validator nodes
Validator nodes are simply full nodes that also have the ability of validating new transactions
that should be added to the chain. In order to do so, they possess a private key with which they sign the transactions
marking them as valid. In exchange of their work, they get back a reward that is given to them each time a new block
Without validator nodes, the whole chain couldn't exist and by becoming one of them, you will contribute to the working of the whole Commercio.network ecosystem.
Become a validator node
