Why? You can do the check after the game (as you would have done in real world). It can be done for example lake this: • Every side makes its sea • Generates a random string • Puts that together and makes a hash • Sends that hash to the other side • The other side does not know your sea, even by trying all seas - it does not have tho random data • After the game, you send the sea and hash • It can be tested if it fits • You can not decide you change your sea in the middle, because your hash would not fit (with a good hash, you could not generate proper "random" data) So it would be the same safety as in real game -- This email has not been checked by an antivirus system.
