Ender Chest

Ender Chests are blocks that can store items. Ender Chests function the same as normal Chests, except that their contents are shared across all other Ender Chests placed in the world, including those placed in The Nether and The End.

Ender Chests cannot be made into Double Chests and can be placed adjacent to each other normally. Ender Chests do not drop their contents when broken. Items placed inside will remain persistent even if all Ender Chests are destroyed, and can be accessed from new Ender Chests. Ender Chests have the same blast resistance as Obsidian, making them immune to explosions. They also emit light and a particle effect similar to that of an Enderman and Nether Portal. Ender Chests have an intended drawback: The contents are not player-specific on SMP. All chests share the same contents and can be accessed by anyone, making it very easy for griefers to steal the chests' contents.

History
The Ender Chest was implemented in snapshot 12w21a.

Trivia

 * Since items are persistent even when all Ender Chests are broken, the player can use them to recover items from anywhere safely, even if they destroy the chest.
 * Ender Chests can be very useful in Hardcore if the player is able to obtain the resources required to make one. At the cost of one inventory slot for the chest, the player gains another 27 extra slots, for a net gain of 26, adding up to a total inventory space of 62 different stacks you can carry.
 * Similar to Obsidian and Chests, Ender Chests cannot be moved by Pistons.
 * By default, each server has one persistent Ender Chest inventory. This means that the player can not create or find an Ender Chest utilizing a different inventory of items than another.
 * Ender Chests can potentially be utilized to pass along items to other players in SMP. This can even extend to sending written messages if the players use Written Books, or convey large amounts of inventory from one area to another.
 * The Ender Chest was based off a suggestion thread on Reddit. This idea was previously made into a mod by Ecu and ChickenBones.
 * In response to some users' feelings on the functionality of Ender Chests, Jeb is planning to test a feature he has yet to specify in relation to them.
 * A good tactic for moving large inventories using only one Ender Chest is to place it, place whatever you need inside it, break the chest, and then place it wherever you need to move the items to. The items will not be destroyed or dropped in the process.
 * You cannot duplicate items with 2 ender chests. If you take items out of one, and open another, the items you took will not be there.
 * Despite being made out of obsidian, the Ender Chest can be broken with any kind of pickaxe.
