A Decentralized and Secure Blockchain-IPFS Framework for Efficient Data Storage in Web3

Abstract

In the era of web3, blockchain based technologies that leverage the essence of data security and content distribution are transforming the data storage mechanism by eliminating the reliance on centralized servers. Interplanetary File System (IPFS) is one such technology which provides the mechanism to distribute the data without centralization. Many critical applications are being constructed on the principles of blockchain technology to provide data security, integrity and privacy. They are facing storage challenges owing to the data volume growth of transactions. In this research paper, we propose the paradigm shift towards moving forward a more decentralized, secure and censorship-resistant internet, paving way for the next generation of Web3 applications. Our proposed framework works on the Integrated principles of blockchain and IPFS to ensure data security and eliminate the storage cost and challenges. The blockchain sharing mechanism is build using the concept of real time connection for web (WebRTC) where the connection is established between trusted peers. The block consists of essential information required for file retrieval from the IPFS nodes and the password to decrypt the files. As the files are encrypted before uploading to the IPFS nodes using a strong encryption mechanism AES-256, it makes the framework secure from man in the middle attacks which try to fetch the files from the network while being shared.
