Run a node on Concordium#

When you run a node on the Concordium blockchain, you are participating in the Concordium blockchain by validating transactions.

Nodes are required for most things, from using a Concordium wallet to baking. You can choose to run a node yourself or you can have a third-party provider run a node for you. If you choose to run the node yourself, you can choose from four different platforms to run your node: Ubuntu, Windows, MacOS, or Docker/Linux.

System requirements to run a node#

The following are the minimum system requirements for running a node. If your system does not meet or exceed these requirements, you might not be able to run the node properly.

You need a broadband connection to run a node, and Concordium strongly recommends that the node is running around the clock in a reliable place. This is especially important if you’re running a baker node.

If you use a laptop in combination with Docker, sleep mode can cause problems with the Docker container used to run the node.

System requirements#

  • CPU: A quad core CPU or better of a new generation x64 (AMD Ryzen™ 5000 series or Intel® Core™ 11000 series desktop or mobile CPUs or CPU with similar single threaded performance).

  • Minimum 16 GB of RAM.

  • Minimum of 1TB fast SSD disk space available (minimum NVMe PCI Express 3.0 4x SSD).

Platforms#

You can run a node on Ubuntu, Docker, Windows, or MacOS.
