Getting Started

Running a node is the best way to use IOTA. By doing so, you have direct access to the Tangle instead of having to connect to and trust someone else's node. Additionally, you help the IOTA network to become more distributed and resilient.

The node software is the backbone of the IOTA network. For an overview of tasks a node is responsible for, please see Node 101.

To make sure that your device meets the minimum security requirements for running a node, please see Security 101.


Make sure you install Hornet version 0.6.0+ since it is the minimum version that targets IOTA 1.5 (Chrysalis) network. Versions below 0.6.0 (such as 0.5.x) target the legacy IOTA network which is not the focus of this documentation.

To handle a potential high rate of messages per second, nodes need enough computational power to run reliably, and should have following minimum specs:

  • 4 cores or 4 vCPU
  • 8 GB RAM
  • SSD storage
  • A public IP address

The amount of storage you need will depend on whether and how often you plan on pruning old data from your local database.

Hornet exposes different functionality on different ports:

  • 15600 TCP - Gossip protocol port
  • 14626 UDP - Autopeering port (optional)
  • 14265 TCP - REST HTTP API port (optional)
  • 8081 TCP - Dashboard (optional)
  • 8091 TCP - Faucet website (optional)
  • 1883 TCP - MQTT (optional)

The mentioned ports are important for flawless node operation. The REST HTTP API port is optional and is only needed if you want to offer access to your node's API. All ports can be customized inside the config.json file.

The default dashboard only listens on localhost:8081 per default. If you want to make it accessible from the Internet, you will need to change the default configuration (though we recommend using a reverse proxy).

Operating System

Hornet is written in Go and can be deployed on all major platforms using several installation methods.

Hornet ships as a single executable binary (hornet or hornet.exe) and some JSON configuration files; no further dependencies are needed.

Linux (and Raspberry Pi)

Hornet uses several JSON configuration files that can be adjusted based on your deployment and use cases:

  • config.json: includes all core configuration parameters
  • peering.json: includes connection details to node neighbors (peers)

See more details regarding the configuration in the post installation chapter.
