# Overview

The Gensyn Public Testnet was launched in March 2025.  

It brings persistent identity to decentralized AI systems and provides a network to track participation, maintain attribution, make payments, coordinate remote execution, verify untrusted operations, log decentralized training runs, crowdfund large-scale training efforts, and more. 

## What's Live Now

The Testnet is in its final phase ahead of Mainnet. 

The current focus is on [Delphi](https://docs.gensyn.ai/intelligence-market/what-is-delphi), a permissionless prediction market platform where anyone can create markets on any topic, settled by AI. Delphi is the first application launching on Gensyn Mainnet.

#### Previous Phases

Earlier phases of the Testnet included:

* **RL Swarm:** Collaborative post-training via reinforcement learning reasoning over the internet. RL Swarm demonstrated decentralized model improvement through swarm participation. RL Swarm & all Gensyn-hosted nodes have been paused. 
* **BlockAssist & CodeAssist:** Applications that demonstrated how ML models can train directly on human interactions to create personalized, privacy-preserving models. Both have been sunset as focus consolidates around Delphi. All historical data remains on chain.

### Get Involved

| **Community Members**  | Stay up to date on progress, provide feedback, and discuss future developments in the [Discord. ](https://discord.com/invite/gensyn)                                                                                          |
| ---------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Swarm Participants** | Run a node, improve the overall intelligence of the swarm, track your participation, and train your own local model to use as you wish.                                                                                       |
| **Developers**         | Train a local model by participating in the swarm, deploy in local applications without being beholden to an external company, and continually update its parameters in a living, decentralised system.                       |
| **ML Researchers**     | Deploy your own swarm 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. |

### Architecture

The network is a custom Ethereum Rollup dedicated to machine learning and integrated with off-chain execution, verification, and communication frameworks. 

#### Roadmap

The Testnet will follow a phased rollout, with each phase introducing new features derived from the infrastructure that Gensyn builds. 

This gives the community a chance 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 to inference. The final phase will culminate in the **Mainnet** launch, *with real economic value transacted via the chain.*
