Extend Hyperledger Besu using plugins

You can extend Hyperledger Besu's functionality by creating Java plugins or using existing open source Besu plugins. Use the Plugin API to get data from any public or private Besu network and feed it into an application or system.

For example, you can create a plugin to add more monitoring functionality or to stream event data to a third-party application. The API exposes data about the following components:

  • Blocks
  • Balances
  • Transactions
  • Smart contracts
  • Execution results
  • Logs
  • Syncing state

Get started by creating a simple plugin.

The following diagram outlines the high-level architecture of the Plugin API.
