Me and my friend have reserved rooms in hotels. I want to handle him golden statue. Both me and him have 1 suit case, 1 lock and 1 key each (each one’s key is for his own lock). We are not allowed to leave our rooms but we are allowed to send each other things via the room handlers, which are not trust-worthy. If they see a golden statue, they steal it. If they see a key, they make themselves identical copies of it. Is there someway using some sequence of transactions that I can transfer the statue securely to my friend?
