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.
