How does the skill ensure data has not been tampered with?

It enforces the use of Merkle root hashes; when data is downloaded, the skill verifies the content against the on-chain hash to ensure perfect data integrity.

Which SDKs are required for this integration?

This skill utilizes the @0glabs/0g-ts-sdk for storage operations and ethers.js (v6) for interacting with the 0G Chain smart contracts.

What is a cross-layer skill in the 0G ecosystem?

A cross-layer skill connects different functional layers of the 0G ecosystem, specifically linking decentralized file storage (0G Storage) with blockchain smart contracts (0G Chain).

Why shouldn't I store file data directly on the blockchain?

Storing large files on-chain is prohibitively expensive and can lead to network congestion. This skill allows you to store the data in a dedicated storage layer while keeping a tiny cryptographic proof on-chain.

Is there a specific EVM version required for the contracts?

Yes, for 0G Chain compatibility, contracts should be compiled using the 'cancun' evmVersion in your Hardhat or Foundry configuration.

Integrates 0G Storage with 0G Chain smart contracts to create verifiable on-chain references for off-chain data.

This skill provides the architectural patterns and implementation guidance needed to bridge decentralized storage with blockchain execution. It enables developers to upload large datasets to the 0G Storage layer while maintaining lightweight, secure references, such as Merkle root hashes, on the 0G Chain. This approach is ideal for building NFT metadata systems, verifiable document registries, and content management solutions that require the security of a blockchain without the prohibitive costs and technical limitations of storing large files directly on-chain.
