Welcome to HORNET

Hornet Logo

HORNET is a powerful, community driven IOTA node software written in Go. It is easy to install and runs on low-end devices like the Raspberry Pi 4. a group of community developers alongside the IOTA Foundation are responsible for building and maintaining Hornet. Hornet is a full-fledged software providing full node capabilities including full support of the Chrysalis network update.

More information about IOTA network protocol can be found on the IOTA website. Technical information for developers is part of the Chrysalis Developer Documentation.


We have upgraded the IOTA network to version IOTA 1.5, also known as Chrysalis. This documentation focuses on running a node as a part of the Chrysalis network (Hornet version 0.6.0+). It is not valid for previous versions of Hornet, such as 0.5.x and below.

By running your own node you have the following benefits:

  • You have direct access to an IOTA network, instead of having to connect to and trust someone else's node.
  • You help the IOTA network to become more distributed and resilient by validating messages and value transactions in the IOTA network,


We will continue to update Hornet with upcoming changes to the IOTA protocol. You can visit the roadmap for more information.
