I don't think it's possible to do revocation in a stateless manner. The token that you are revoking was once valid, and when you decide to invalidate it, this change of state needs to be persisted somewhere. But yeah, if revocation is rare and only few tokens are invalid at any given time (which can be easy by adding an expiry field to tokens), keeping a revocation list is the way to go.
