Hey miner! We're Eternal Evolution.

Skyblock:
In our Skyblock server we do not have a currency, we want people to trade with their items, so if you need cobblestone, maybe trade a diamond for some. You can also check out our villager shop where you can buy items with items, something you gotta check out.
Clans:
Apart from our Skyblock server we have currency on this server, located at "the Market". We are trying to be helpful in any manner, and will always take suggestions in for consideration.
Lets talk a bit about the new way of playing called "Clans". Clans is a new way of playing Minecraft, in many ways the same as Factions. We introduce you to the plugin called Precious Stones, which will hook into Clans, so the blocks you own from Precious Stones, will be available for all your clan members too!

Information about both of these plugins can be found here.

Overall information:
We run Spigot enhanced servers to reduce the lag for you, the players. We've also got Bungee Cord to combine all our servers together, enabling you to transfer between them, without having to disconnect from the current server, to add another IP, and then join the new server, simply do /server for a server list and /server to transfer.
Best Regards, Eternal Evolution Staff.
