โฐ 1.0 What's a persistent world?
It is a world that continues to evolve in the absence of players, while other people continue to play.
When the player reconnects he will find what he has built and left, as long as other players have not broken it or stolen it.

โฐ 2.0 Things to know about persistent objects
Persistent objects remain the same after a reboot of the server but deteriorate slowly with each reboot, i.e. they lose life points if they are abandoned, in the same way that the material wears out over time in real life. From time to time think about repairing them and doing maintenance. If they run out of life points after the reboot, they'll disappear.
It takes about ten days for an abandoned object disappear. Note that maintenance and upkeep give them life and you gain experience points at the same time.
