 Adding the `--witness` parameter to the startup command, full node will run as a super representative node. The super representative node supports all the functions of the full node and also supports block production. Before running, make sure you have a super representative account and get votes from others. Once the number of obtained votes ranks in the top 27, your super representative node will participate in block production.
