To upload files to 0G decentralized storage, the Skill uses the ZgFile API and Indexer to split files into chunks, organize them as a Merkle tree, and distribute them across storage nodes, returning a root hash for verifiable retrieval.

Merkle-tree based file chunking for decentralized storage works by splitting your data into segments, indexing them via ZgFile, and organizing the segments into a cryptographic tree structure distributed across nodes for secure, verifiable retrieval.

Yes, uploading to 0G storage requires a funded wallet. You need to configure environment variables including PRIVATE_KEY, RPC_URL, and STORAGE_INDEXER, along with Node.js >= 18, the 0G TS SDK, and ethers to execute the Merkle-tree upload.

You can use the 0G TS SDK to upload large files by chunking and indexing the data via the ZgFile API. This process handles large file distribution across storage nodes and generates a root hash for later verification.

Required environment variables for 0G storage uploads include PRIVATE_KEY, RPC_URL, and STORAGE_INDEXER. These must be configured alongside the 0G TS SDK and ethers within a Node.js >= 18 environment to process the Merkle-tree upload.

To retrieve documents stored on 0G storage after upload, you use the root hash returned by the Merkle-tree upload process. This root hash serves as a verifiable reference to locate and validate your chunked data across the distributed storage nodes.
