SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Verifies that files stored and retrieved from 0G Storage have not been tampered with by computing Merkle proofs and comparing root hashes to trusted values.

Core Features & Use Cases

  • Merkle root computation: Build a Merkle tree from a ZgFile to extract the canonical root hash and prove data identity.
  • Integrity verification: Compare computed hashes against expected roots or run the Indexer download with automatic proof checking before trusting a file.
  • Use case: Ensure GPU datasets, model weights, and agent-uploaded artifacts match the hashes recorded on the 0G Registry before processing or payment.

Quick Start

Compute the Merkle root hash of the downloaded file and compare it against the recorded root to ensure integrity before trusting the data.

Frequently Asked Questions about Merkle Verification

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I verify 0G Storage file integrity after downloading?▼

To verify 0G Storage file integrity, compute the Merkle tree root hash of the downloaded ZgFile and compare it against the trusted root hash recorded on the 0G Registry to detect any tampering before processing.

What is Merkle root hash verification used for in 0G Storage?▼

Merkle root hash verification is used to prove data identity and ensure files like GPU datasets and model weights retrieved from 0G Storage have not been tampered with before processing or payment.

Do I need Node.js to compute Merkle proofs for 0G Storage files?▼

Yes, you need Node.js 18+ and the @0glabs/0g-ts-sdk to build Merkle trees from ZgFile objects, compute root hashes, and securely verify file downloads.

Can I run automatic hash verification during an Indexer download?▼

Yes, you can run the Indexer download with automatic proof checking enabled to validate the Merkle root hash on the fly, ensuring the file matches the recorded hash before you trust it.

What are the limitations of using Merkle tree verification for file downloads?▼

You must maintain disciplined file handle closure when generating Merkle trees to ensure secure hash comparison, and verification requires a trusted root hash value to compare against the computed result.

How do I validate agent-shared datasets before processing them?▼

To validate agent-shared datasets, build a Merkle tree from the downloaded ZgFile to extract its canonical root hash, then compare it against the expected hash recorded on the 0G Registry to confirm data integrity.
