EconomicMarket

Players reach the market through a web interface that the server hosts on port 5888. From a browser they can view their backpack items, list them for sale in real time, and buy listings from other players, with emeralds changing hands directly from their inventories. Virtual wallets are part of the system, though the currency model is kept simple rather than layered.

The auction house extends the market with timed auctions that have starting prices and minimum bid increments. Thirty invented companies, carrying Chinese-style names such as NE Traffic, Microsoft Cube and Apple Corp, trade on a stock market where prices shift at random every minute and shares are paid for in real emeralds. A real-time leaderboard ranks players by the emeralds they hold. An auto-bidding mode, called Sky Lantern, bids on a player's behalf until it wins.

Access is protected by online authentication: a player must be logged into the game before the web panel opens. Because the server is built on Java's built-in HttpServer, it needs no external libraries beyond Fabric or Quilt. It runs on dedicated servers, LAN games and singleplayer worlds opened to LAN, and everything is configurable, with data kept in the server's config folder. Custom HTML, CSS and JavaScript files can be placed in a dedicated configuration directory to replace the default web interface. Files are published for 1.20.1 on Fabric and Quilt, and the code is open source under the MIT License.
