SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Combine 0G Storage with 0G Chain smart contracts to create on-chain references to off-chain data. This enables NFT metadata storage, content registries, and verifiable document systems without storing large payloads on-chain.

Core Features & Use Cases

On-chain references to off-chain data via root hashes
NFT metadata storage patterns and content registries
Verifiable document systems with auditable links between chain and storage

Quick Start

Upload data to 0G Storage, deploy or interact with a registry contract on 0G Chain, and store the root hash on-chain to create a verifiable link to off-chain data.

FAQPage Schema

How do I link off-chain NFT metadata to on-chain references using a registry pattern?▼

To link off-chain NFT metadata to on-chain references, you upload the data to 0G Storage, deploy a registry contract on 0G Chain, and store the root hash on-chain to create a verifiable connection to the off-chain payload.

What is the best way to store large verifiable documents on a blockchain without high gas costs?▼

The best way to store verifiable documents without high gas costs is keeping the payload in 0G Storage while storing its root hash on-chain using a registry contract, ensuring the data remains auditable and verifiable across both layers.

Do I need Node.js and the 0G SDK to create on-chain references for off-chain data?▼

Yes, you need a Node.js environment and the 0G SDK installed to upload data to 0G Storage and interact with the 0G Chain registry contract to successfully store the root hashes on-chain.

How does a content registry handle the connection between off-chain storage and on-chain root hashes?▼

A content registry handles the connection by mapping a distinct registry contract on 0G Chain to the off-chain data location, storing the root hash as an on-chain reference to guarantee the integrity and auditability of the 0G Storage payload.

Can I use this registry pattern for deployment pipelines that require auditable off-chain storage?▼

Yes, this registry pattern is specifically applicable to deployment pipelines requiring auditable off-chain storage, allowing systems like NFT metadata and verifiable documents to maintain secure links between 0G Storage and 0G Chain.
