• In a data-driven era, the need for secure, efficient, and user-centric
storage solutions has surged.
• Traditional centralized models face significant challenges in
privacy, ownership, and scalability.
• Blockchain technology, with its decentralized, transparent, and
tamper-resistant nature, has emerged as a powerful tool for
creating such decentralized storage systems. By leveraging
blockchain, decentralized file storage ensures data integrity,
enhances security, and provides users with greater control over
their data.

Abstract

4. • Decentralized file storage is a promising solution for ensuring
secure and reliable storage and sharing of digital files without
relying on centralized entities like cloud providers.
• Blockchain technology, with its decentralized, transparent, and
tamper-resistant nature, has emerged as a powerful tool for creating
decentralized file storage systems.
• As data becomes increasingly valuable and sensitive, decentralized
file storage using blockchain technology can provide a reliable and
secure alternative to centralized storage providers

Introduction

5. NAME OF THE INSTITUTE, PARUL UNIVERSITY
PIT , PARUL UNIVERSITY
• In the age of increasing digital data generation, individuals and
organizations face challenges related to centralized file storage
solutions. Traditional cloud storage providers raise concerns about
data security, privacy, ownership, scalability, and reliance on a
single point of control.
• The existing options often lack transparency and can be subject to
censorship, data breaches, and vendor lock-in. This creates a need
for a decentralized file storage system that leverages blockchain,
smart contracts, and distributed storage to address these
challenges.

Problem Statement

6. • Allow users to securely upload, retrieve, and manage their files while
maintaining ownership and control over their data. Should provide a
viable alternative to traditional cloud storage services, offering
increased security, transparency, and data accessibility.
• The project aims to provide a decentralized ecosystem that empowers
users with a self-sovereign approach to data storage, reduces reliance
on centralized entities, and explores the potential of emerging
technologies to reshape the future of data management.

• React.js Frontend: Developing a user-friendly frontend using React.js
to interact with the smart contracts and IPFS.
• Node.js Backend: Node.js is a popular choice for developing
blockchain applications due to its performance, scalability, and
extensive ecosystem.
• Polygon Integration: Polygon provides a bridge to Ethereum, so
smart contracts are deployed to the Polygon network.
• Scalability and Optimization: Polygon offers scalability benefits, but
it's essential to design your system efficiently. Use IPFS for
decentralized storage and leverage Polygon's fast and low-cost
transactions.
• Smart Contract Development (Solidity): Develop smart contracts to
manage file uploads, ownership, and payments on the Polygon
blockchain.

Tools & Technology

11. NAME OF THE INSTITUTE, PARUL UNIVERSITY
PIT , PARUL UNIVERSITY
• MetaMask: is widely used in blockchain applications for several
reasons, especially when building or interacting with decentralized
systems, such as your Decentralized File Storage System using
Blockchain.
• IPFS Integration: Integrate IPFS (InterPlanetary File System) to store
the actual file data. When a user uploads a file, the file's data is stored on
IPFS, and the hash of the data is recorded on the File Storage Contract.
Using IPFS libraries to interact with the IPFS network from smart
contracts and React.js frontend.
• Web3:Web3 itself doesn't inherently provide storage space, but
decentralized file storage systems built on Web3 principles, such as IPFS
(InterPlanetary File System) or Filecoin, can offer scalable storage
solutions.
• UI/UX Design: Design an intuitive user interface that guides users
through the file upload, retrieval, and payment processes.
