Decentralized Cloud Storage

Description

The Decentralized Cloud Storage project aims to provide a secure and decentralized way to storage files using blockchain technology. It allows users to upload files, create blockchain-based assets for each file, and retrieve files based on blockchain records.

Features

  • File Upload: Users can securely upload files through a user-friendly interface.
  • Asset Creation: Each uploaded file generates a unique asset on the blockchain, associated with its IPFS address.
  • File Retrieval: Users can retrieve uploaded files based on the blockchain records.

Smart Contract

The smart contract contains two functions:

  • create_asset: This function creates an asset and returns the hash key.
  • fetch_asset: This function fetches the asset using the hash key.

Smart Contract Code Snippet

#[derive(Default)]
pub struct Contract;

impl Contract {
    pub fn create_asset(&self, asset_data: Vec<u8>) -> H256 {
        let hash_key = keccak256(&asset_data);
        // store asset_data in IPFS and save hash_key on the blockchain
        hash_key
    }

    pub fn fetch_asset(&self, hash_key: H256) -> Vec<u8> {
        // retrieve asset_data from IPFS using hash_key
        asset_data
    }
}
