What is goloop?

Goloop is the client for the ICON network officially supported by the ICON Foundation. Its purpose is to maintain the state of the decentralized blockchain in a robust, failsafe way.


There are 6 main layers to the goloop client:

  • Transaction handler for interaction with users
  • Transaction handler for internal usage
  • Communication with the execution environment
  • Execution environment
  • Data storage
  • Peer-to-peer communication

You can learn more about the transaction-processing system in the section entitled Transaction processing in ICON.

The goloop program is built using the go (opens in a new tab) programming language, which is popular for system-level and cloud-native applications. It is very modular and can be repackaged to modified versions of the existing components, for example to use a different consensus protocol.

The goloop project is open-sourced, and we welcome collaboration. Check it out here on GitHub (opens in a new tab), and contribute something or experiment with it if you would like.
