Nostr Game Engine v0.0

A Game Engine with P2P networking and essential Nostr functionalities

For those new to the project: Nostr Game Engine (NGE) is a “nostrified” version of @jmonkeyengine .

Core components are being modernized and progressively replaced with a peer-to-peer, nostr-based implementations.

§In-game Ads

This release brings many bug fixes and improvements, but the standout feature is in-game advertising.

In-game ads have been discussed for decades, yet today’s industry standard still leans on disruptive and annoying formats. With NGE, we’re experimenting with approaches that are immersive, peer-to-peer, and player-friendly.

This system is powered by the nostrads protocol, designed to bring ads to nostr in a privacy-friendly and permissionless way.

From a game developer’s perspective, integration is simple:

• Set up a lightning address for your game
• Mark some surfaces in your 3D models as ad-spaces
• Add a few lines of code to initialize the ads system

And just like that, your game becomes monetizable.

For a deeper dive into nostrads, see the dedicated page.

As with the previous release, this version comes with a purpose-built demo app to show the ad system in action, using fake retro-futuristic ads, but you get the idea.

§Experimental Android Support

The engine now builds and runs on Android. All dependencies have been ported to API level 33.

§Component System Improvements

• Simplified global object access in components
• Deprecated all receiveX methods in favor of a single getGlobalInstance() method

More in the docs

§Other Improvements

As part of the NGE development, several improvements were made to the jMonkeyEngine codebase. These are included in this release and are either in review or merged upstream:

• Improved render parity with Blender
• Faster, more memory-efficient glTF loading
• Global illumination support for local lights
• Improved tonemapping

§Updates to Nostr4j

Nostr4j, the high-performance nostr client library powering NGE, also gets a major update:

• Improved resilience to network issues
• Blossom protocol support
• More flexible fetching strategies
• Wallet abstraction + NWC support (NIP-47)
• Managed event deletion (NIP-09)
• Proof of Work support (NIP-13)
• LNURL resolution

§What’s Next

• Browser port (WebGL + TeaVM)
• Stabilize Android support
• Lay groundwork for future features

There are great things ahead, but first we need to make sure the foundation is solid!

§Funding and Support

A big thank you to @78733...851f2 for supporting this work through the eleventh wave of Nostr grants.

We’d also like to recognize our first four donors, who quietly contributed to our Geyser fund even before it was officially announced. Your support means a lot!

On that note, If you’d like to support the project, contributions via the support page will directly help sustain long-term development.
