You can set up and change your commission as a validator.
A validator is entitled to charge any commission rate. The minimum commission would be 0% and the maximum commission would be 100% of the rewards earned.
You are allowed to change the commission rates as many times as you would like.
As a validator, it is one of your responsibilities to inform the community on commission changes. See Validator Responsibilities.
