The official node software that runs on the IOTA Mainnet and Devnet
The IRI (IOTA reference implementation) is open-source Java software that runs on the IOTA Mainnet as well as the Devnet. This software defines the current IOTA protocol, which allows nodes to do the following:
- Validate transactions
- Store valid transactions in a ledger
- Allow clients to interact with the them through a an HTTP API
This is beta software, so there may be performance and stability issues. Please report any issues in our issue tracker.
To run IRI, you need the following:
- 4GB RAM
- 64-bit processor
- A public IP address that's either static or connected to a dynamic DNS service such as duckdns.org
- Ports 15600 and 14265 must be open
You can do one of the following:
- Download the pre-built Java file
- Compile the Java file yourself
Or, if you use Docker, you can run the pre-built Docker image
Downloading the pre-built Java file
After every release, we upload a pre-built Java file onto the GitHub Releases page.
You can simply download the latest
