Minecraft wiki entry for Player_versus_Player, associated text: If the base is being raided, and your hand is forced, activate the self-destruct on your base. It is very important to keep one on hand at all times and also have an escape. The self-destruct must be designed to overwhelmingly destroy all life and loot inside the base and the base itself but also be well-hidden. This is hard and so you should experiment. In times of need, start the lethal countdown and escape. Ender chests are good for these kinds of bases, as they don't drop their content and it can be accessed anywhere as long as you have another one.
