SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Uploading files to the 0G storage network is complex because it requires chunking data, generating Merkle trees, coordinating wallet-backed RPC calls, and never losing the root hash, so this Skill provides a repeatable workflow that enforces those safeguards while closing file handles correctly.

Core Features & Use Cases

  • Merkle-first workflow: orchestrates ZgFile creation, Merkle tree generation, and root hash capture before any upload attempt.
  • Controlled indexer upload: wraps Indexer.upload in try/finally with wallet authentication, RPC URL validation, and error logging so transactions do not leak resources.
  • Use Case: store a verified machine-learning dataset or critical documents, return the root hash for future retrieval, and keep credentials out of source code.

Quick Start

Upload the latest dataset to 0G Storage through the configured Indexer and report the root hash.

FAQPage Schema
How do I upload files to 0G decentralized storage using Node.js and ethers?▼

To upload files to 0G decentralized storage, this skill chunks data, generates Merkle tree root hashes via ZgFile, and coordinates wallet-backed RPC calls with ethers. It requires setting environment variables for authentication and indexer routing to execute the secure transfer.

Why does uploading to 0G storage require generating a Merkle tree root hash?▼

Generating a Merkle tree root hash verifies data integrity before the 0G storage network accepts the upload. This process structures file chunks cryptographically, ensuring the decentralized indexer can validate that your uploaded dataset remains uncorrupted.

What environment variables do I need to configure for 0G storage uploads?▼

Configuring 0G storage uploads requires the environment variables PRIVATE_KEY, RPC_URL, and STORAGE_INDEXER. These credentials authenticate wallet-based RPC interactions and route the Merkle-verified file chunks to the correct indexer.

Can I use the 0g-ts-sdk to store machine learning datasets on 0G storage?▼

Yes, you can use the 0g-ts-sdk to store machine learning datasets on 0G storage. The workflow handles large files by preparing data chunks and capturing the Merkle root hash, allowing you to securely store critical datasets and return the hash for future retrieval.

What is the best way to prevent resource leaks during 0G indexer uploads?▼

The best way to prevent resource leaks during 0G indexer uploads is wrapping the Indexer.upload call in a try/finally block. This controlled approach ensures file handles close correctly even if wallet authentication or RPC interactions fail.
