RubySpire

RubySpire is a lifesteal survival server where the economy is run by the players. Every player kill moves a heart: the killer gains one and the victim loses one.
You start with 10 hearts and can reach 20, by winning fights or by buying hearts with money you earn in game. Run out and you're sent to the Death Realm until you or a friend pays to bring you back. New players are protected for their first 2 hours, so you get time to set up before anyone can come after your hearts.
Most of the money comes from what you farm, mine and sell. The auction house is where players buy and sell with each other, and you earn Rubies just for playing and voting, which you can spend on crates, spawners and more. Play solo or make a group with your friends. Raiding and griefing are allowed, so build carefully.
If you'd rather settle things one on one, the hub has an arena for wager duels. Both players put money in, pick a kit and fight for the pot. Losing a duel doesn't cost you any hearts.
The world is 100,000 by 100,000 blocks with random teleport, so there's always fresh land to claim. Java and Bedrock players are on the same server, so you can join from PC, phone or tablet.
No pay-to-win: nothing is sold for real money. Hacking, x-ray and duping will get you banned.
