Auto Drive: Autonomys Network's Data Access Layer

Auto Drive is a decentralized content-addressed storage solution built on the Autonomys Network, leveraging its underlying permanent storage layer known as the Autonomys Distributed Storage Network (DSN). It provides users with a secure and efficient way to store, share, and manage digital assets with the assurance of long-term data persistence.

Auto Drive offers a user-friendly interface for uploading and downloading files, as well as an SDK and API for developers to integrate storage capabilities into their applications.

Features

• Data chunking and reassembly
• Metadata management
• Blockchain integration for data storage
• Transaction management
• RESTful API for data operations

Getting Started

Prerequisites

• Node.js (v14 or later)
• Yarn
• Access to an Autonomys Network node

Installation

1. Clone the repository:

   git clone https://github.com/your-username/autonomys-data-storage.git
   cd autonomys-data-storage
   

2. Install dependencies:

   yarn install

• GET /transaction/:cid: Get transaction result for a specific CID
• GET /transactions: Get all transaction results
• GET /fromTransactions/:cid: Retrieve data directly from blockchain transactions

Architecture

The service is built with the following components:

1. Storage Manager: Handles data chunking, reassembly, and metadata management
2. Transaction Manager: Manages blockchain transactions for data storage
3. API Layer: Provides RESTful endpoints for interacting with the service

Testing

Run the test suite:

yarn test
