 Limitless, abundant productivity and creativity brought by AGI will free humanity to pursue our highest potential. AGI is poised to contribute [trillions](https://www.mckinsey.com/capabilities/mckinsey-digital/our-insights/the-economic-potential-of-generative-ai-the-next-productivity-frontier#key-insights) to the global economy annually, transform industries by driving the marginal cost of intelligence toward zero, and morph society by accompanying us as thought partner and companion. This global-scale change could uplift all of humanity.

-A global-scale technology revolution requires both a global-scale technological infrastructure and a global-scale alignment mechanism. A world AI infrastructure could frogleap the confines of data-centers and support exponential scaling towards AGI so that humanity could benefit from unlimited intelligence. A global scale coordination and alignment mechanism ensure that the benefits of AI can be widely, fairly, and safely distributed.

 - **Transparency**: Centralized AI systems operate as black boxes, with opaque decision-making processes and no clear data provenance. Users who provide training data rarely receive adequate rewards for their contributions, and the system lacks transparency in how value is distributed. _Decentralized AI fosters transparency by providing open, auditable decision-making processes and verifiable data sources, ensuring accountability at every step._ **0G’s modular architecture enables transparent data traceability and verifiable AI models, making every decision and data source traceable.**

 The validator selection process described here applies **only to the testnet**. Mainnet will have a different selection mechanism.
 While it's possible to run nodes (ex: DA node vs Validator Node) independently, your chances of being selected as a _validator_ increases if you run multiple node types.
