Usage

rad delegate add <did> [--to <rid>] [<option>...]
|
|
rad delegate remove <did> [--to <rid>] [<option>...]
|
|
rad delegate list [<rid>] [<option>...]
|

|
|
The `add` and `remove` commands are limited to managing delegates
|
|
where the `threshold` for the quorum is exactly `1`. Otherwise,
|
|
the verification of the document will not be able to gather enough
|
|
signatures to pass the quorum.
