It’s a great honor to announce that we are launching the Testnet version of our open-source Java SDK alongside the world’s first blockchain-powered Minecraft Server — EnjinCraft.

The Blockchain SDK for Java: Out Now!

Java developers can now effortlessly create, manage, and integrate blockchain assets into their platforms using the language they know and love.

As a developer, you can use this SDK easily and customize it freely.

We have adopted an open-source codebase as a testament to the collaborative nature of the Java community. We encourage you to recreate this SDK however you wish, build on top of our framework, and build new SDKs that can do things we never even imagined.

Our flexible blockchain development platform provides a structured API that makes it simple for Java developers to communicate with the Ethereum blockchain via the Trusted Cloud.

Minting sophisticated blockchain assets on Ethereum is now easier than ever.

An immensely popular coding language, Java is used to develop:

  • Games: Minecraft, Runescape
  • Web Applications: Gmail, Google Docs
  • Applications: Blu-ray Disc Java, Open Office
  • Android Apps: All native Android apps

Java is widely considered one of the most stable and reliable ways to build large systems and is undeniably one of the most popular programming languages in the world.

It is a robust option for developing game servers, especially those that host intricate multiplayer experiences.

Therefore, our Java SDK provides an easy option for server-side game logic that is also useful for game developers already building with our Platform API, as well as the Unity and Godot SDKs.

Enjin’s Minecraft Plugin: Coming Soon

With the launch of our new demo server, the most popular game in the world, played by 91 million people, now features intuitive blockchain asset integration thanks to our Minecraft Plugin.

But this isn’t our first time releasing tools for Minecraft servers.

Our Minecraft e-Commerce plugin, DonationCraft, boasts over 5 million downloads and has helped server owners earn millions of dollars.

While DonationCraft was a simple plugin that enabled servers to accept PayPal and credit card payments, our Minecraft Plugin will soon enable server owners to integrate a full-fledged blockchain economy — a potentially transformative capability.

If you’re a Minecraft server owner, you will be able to integrate real-world economies of value, provide your players with tangible ownership over the in-game assets and currencies you offer them, and create assets that can spill over into your chat rooms, websites, and the multiverse.

The potential of this is massive, but the concept is completely foreign—which is why we’ve also launched the closed beta version of our very own Minecraft demo server that is built with our plugin: EnjinCraft Server One.

EnjinCraft Server One: Available in Closed Beta

Built with our Minecraft Plugin on Mainnet, the purpose of EnjinCraft Server One is to enable you, as a server owner, to experience how powerful in-game assets become when they run on the Ethereum blockchain.

Blockchain assets are simply amazing—you can distribute them via your server or completely separate games, apps, websites, online stores, chat rooms, and social media platforms. Your players can own them forever, trade them freely, and—of course—jump into your server and use them seamlessly.

The new forms of social gameplay you can create with our tools can spill out of your server and into people’s lives in previously impossible ways.

After 10 years of supporting the Minecraft community by providing tools that enable players to connect on a personal level, our debut Minecraft server features the world’s first peer-to-peer blockchain asset trading, hourly loot drops, and the ability to use your blockchain assets within the server.

Take the scenic route and visit our visionary CTO’s humble abode.

Coming iterations of EnjinCraft Server One will feature extended gameplay and interoperability of assets between Minecraft servers and other games, apps, and websites.

Yes, you heard that correctly: you will be able to receive assets from other games, apps, and websites and use them in our Minecraft server — and vice versa.

If you want to see the world’s most robust blockchain-integrated Minecraft server for yourself, join our community in the hunt for blockchain assets.

The World’s First Blockchain Assets for Minecraft

The Enjin Army has already stumbled upon the treasure trove showcasing the world’s first blockchain-based Minecraft assets.

Now, it’s my pleasure to share even more epic news: the two most unassuming assets in the EnjinCraft collection will become Multiverse items!

Click the images above to view the corresponding assets on the blockchain.

The Wooden Sword and Wooden Shield are now playable on EnjinCraft Server One and will soon also be usable in over 30 other games!

Here is the current list of games and platforms these two humble multiverse items will be usable in, along with a rough estimation of when you will be able to experience playable, blockchain-integrated releases of each:

Each game developer will have complete freedom to redesign these in-game assets to suit their game’s environment, so the Wooden Sword and Shield will provide you with unique inventory in each game.

For example, here’s what you’ll get when you use these two items in Space Misfits, a 3D space sandbox MMO:

Space Misfits will release their blockchain-integrated alpha game on May 25.

What are you waiting for?

Happy Birthday, Minecraft! 🎉

To celebrate the Minecraft community’s decade of unabashed creativity, we’re hosting a giveaway of blockchain assets that can be used in EnjinCraft Server One and beyond.


This unique set of multiverse items will soon be integrated into EnjinCraft Server One and more than 30 different games.

Oindrasdain Axe, Aeonclipse Key, Stormwall Shield. Click the images above to view each of these items on the blockchain.

As an owner of one of these items, you will be able to travel from game to game, using it and reaping benefits and rewards everywhere you go.

These multiverse items are not yet supported by EnjinCraft Server One, but when they are usable in the server, they will appear in your Minecraft inventory.

To claim your item, just scan this QR using the Enjin Wallet. A blockchain asset will automatically be sent to your secure wallet.

If you don’t already have the Enjin Wallet, download it now to start scanning!

What’s Next?

  • Blockchain SDK for Godot: An open-source SDK for Godot developers to use, alter, and recreate based on their specific needs.
  • Binance DEX Integration for Enjin Wallet: Enabling users to post bids to Binance’s decentralized exchange without leaving the secure Enjin Wallet.
  • Blockchain SDK for Unreal Engine: Enabling Unreal developers to integrate decentralized economies into their AAA and indie titles.
  • Website Upgrade: Tailored for adoption, is being rebuilt from the ground up to better communicate the benefits of our technology stack.
