The Gensyn Public Testnet brings persistent identity to decentralised AI systems and provides a network to track participation, maintain attribution, make payments, coordinate remote execution, verify untrusted operations, log decentralised training runs, crowd-fund large-scale training efforts, and more.
The network is a custom Ethereum Rollup dedicated to machine learning and integrated with off-chain execution, verification, and communication frameworks.
Phase 0
The first phase of the Testnet focuses on tracking participation within RL Swarm, our application for collaborative post-training via reinforcement learning reasoning over the internet. Connecting an RL Swarm node to an on-chain identity provides a consistent view of individual node contributions.
*Update 30/04/2025*: The Gensyn Testnet has a new swarm with a more difficult dataset and larger models (up to 72B out-of-the-box). Update your node and run the new swarm using the new release.
*Update 25/06/2025*: RL Swarm has a new backend: GenRL. This is a complete overhaul to the environment, game, and training logic. RL Swarm can now work with any environment and we’ve incorporated the open source Reasoning Gym library to include >100 out-of-the-box. A prebuilt Docker image is also now available for easier deployment.
*Update 06/08/2025*: The Gensyn Testnet has a new application, BlockAssist, the open-source AI assistant that learns by watching you play Minecraft. It trains locally and runs on your device, open source and sovereign.
Get involved
- Participants: Run a node, train models locally and/or collaboratively, take the future of Artificial Intelligence into your own hands, and track your participation on a global decentralised stage.
- Developers: Add passively trained assistance models to your applications, improve them in global swarms across all of your users devices, and remove your reliance on “god models” from external providers.
- ML Researchers: Deploy your own swarms for others to join, train on new datasets, solve new problems, construct new objectives, incentivise participation and explore the space of decentralised AI with an entirely new infrastructure stack.
- Community Members: Stay up to date on progress, provide feedback, and discuss future developments in the Discord.

Roadmap
The Testnet will follow a phased rollout, with each phase introducing new features derived from the infrastructure that Gensyn builds. The Testnet will allow the community to stress test the protocol under real-world conditions and provide feedback on features and direction during the rollout. As phases progress, more applications will become available - covering the full ML lifecycle from pre-training through inference.
The final phase will culminate in the Mainnet launch, with real economic value transacted via the chain.
