HORNET is a lightweight alternative to IOTA's fullnode software “IRI”

HORNET - The IOTA community node

HORNET is a lightweight alternative to IOTA's fullnode software “IRI”. The main advantage is that it compiles to native code and does not need a Java Virtual Machine, which considerably decreases the amount of needed resources while significantly increasing the performance. This way, HORNET is easier to install and runs on low-end devices.

Available plugins

TangleMonitor

• Download the latest TangleMonitor source code

git clone https://github.com/unioproject/tanglemonitor.git

• Modify the config.json to fit your needs
  • "tanglemonitorpath" has to point to the frontend folder of the TangleMonitor source code
  • Add "Monitor" to "enableplugins"
  • Change "host" to "0.0.0.0" if you want to access TangleMonitor from anywhere
  • Only change the "port" and the "apiPort" if you redirect them back to the default ports, because they are hardcoded in the frontend

  "monitor": {
    "tanglemonitorpath": "tanglemonitor/frontend",
    "domain": "",
    "host": "127.0.0.1",
    "port": 4434,
