IBFT 1.0

Besu nodes can participate (submit transactions and receive blocks) in a Quorum IBFT 1.0 network but cannot be a validator.

To connect to a Quorum IBFT 1.0 network:

  1. In the Quorum IBFT 1.0 genesis file, update the consensus protocol specified in the config property from istanbul to ibft:

        "config": {
         ...
         "ibft": {
         ...
        }
    
  2. Use the --genesis-file option to specify the IBFT 1.0 genesis file.
