## Description

Udhaykumar Balakrishnan presents a hands-on walkthrough of the 0G SDK, showing developers how to integrate decentralized storage and compute into their applications. This tutorial covers both the 0G Storage SDK for uploading and downloading files across a global decentralized network, and the 0G Compute SDK for running AI inference on a decentralized marketplace of models.

The session begins with an introduction to 0G Storage, explaining how it provides fast, secure, horizontally scalable storage designed for AI workloads. Using the TypeScript starter kit, Udhaykumar demonstrates how to set up the SDK, configure RPCs and private keys, upload files with a root hash identifier, and download them from the network. Developers learn how the SDK handles chunking, Merkle trees, and verifiability checks seamlessly.

In the second half, the workshop dives into 0G Compute, a decentralized AI marketplace where providers can list models and users can query them without API keys or subscriptions. Udhaykumar walks through the starter kit, shows how to set up a broker and ledger, list available models like Llama 3.3 and DeepSeek, and run inference queries with verifiable results. The tutorial also demonstrates balance checks, funding, and refunds directly through the SDK.

With clear code examples, live demos, and references to documentation and starter kits, this walkthrough provides everything developers need to start building dApps and AI-powered projects on 0G.
