For data availability, anyone could be able to rebuild whole state from the data on chain so account balance and at least matched orders are always exposed.

Because account is somewhat expensive in L2 (so one could not change his account frequently ) I am afraid it is not too difficult to recognize who actually owning a specified account?

So for the most simple way, just use a collision-resistant order id may be enough to protect one's order from being read by other?

my main concern is not the traded orders. but the put-then-cancel orders.
