I have stored some data on the Tangle using MAM in restricted mode. Can this existing stored data be revoked, at any time, in some way? In the MAM API I could not find such an option. Note: I am not talking about changing the sideKey.
Here are my alternative (NOT OPTIMAL) solutions: 1) Add a validity dateTime to the stored data. After this dateTime the stored data should not be used. 2) Add a link to the stored data. The receiver of this data should check this link if the data is revoked.
