## Signum Node (Mainnet)

The **Signum Node** is an integral part of the blockchain. It loads and synchronizes the entire blockchain, including wallet functionality and the REST API.

Mainnet is Signum's main public production blockchain, where transactions of real-world value take place on a distributed ledger. When people and exchanges discuss Signum pricing, they talk about Mainnet Signum.

**It would be best to have a Signum node running continuously with a fully synchronized blockchain.**

You can access a quick guide for running a Mainnet node by clicking the following link:

## Signum Node (Testnet)

In addition to the mainnet network, there is also a public test network. They are used by developers or smart contract developers to test updates or smart contracts in a production environment before deploying them to the mainnet network. Think of it as an analogy between a production workstation and a staging server.

Thanks to this type of network, development teams can carry out tests without affecting the operation of the original network.

**It would be best to have a Testnet Signum node running continuously with a fully synchronized blockchain.**
