FamilyJewels is a server-side plugin designed to be provide a certain level of protectection against X-Ray cheaters. Like other anti xray plugins, FamilyJewels modifies the block information before it is sent to the client. This technique doesn't save any modified block data to your world.
Unlike other anti-xray plugins FamilyJewels strives to provide an anticheat experience that does not impact a legitimate player in any way. Someone who is playing legitimately should never know that FamilyJewels is installed. Since we strive to have no impact on legitimate players, you may find that FamilyJewels is not as effective as other antixray plugins and some ores may still be visible in caves. We feel this is a fair trade off, but you are welcome to compare for yourself:

Any block that is not directly exposed to air will be sent to the client as smooth stone. When a player begins digging, any nearby blocks are updated and sent to the client which will cause them to appear before any blocks are broken. It is possible that some extremely laggy players will see smooth stone turn into ore immediately after digging, but this is rare.

While we personally have been running this plugin for many months, we cannot guarantee that it won't break your world. Please make backups.
