Decentralized Storage for Educational Resources

Abstract

The growth of blockchain over the last ten years has been astounding: from bitcoin to over 2,000 altcoins, and from decentralized electronic payments to programmable transactions, by complicated tokens and smart contracts controlled by autonomous entities. The technological aspects of blockchain are developing at the same time as the new generation of blockchain applications are also developing. This paper considers one such sphere, to develop a decentralized solution for accessing Educational Resources which will alleviate the issues due to the single point of failure of centralized systems, democratize access to educational content and provide a facile experience for users who are not exposed to web3 technologies. This platform was developed by implementing Smart Contracts using Solidity and deploying them on the Ethereum blockchain to store educational resource metadata and files on the Inter Planetary File System (IPFS). Interfacing of blockchain and the frontend is done using the web3.js. The platform is more tenacious and fault-tolerant than systems using a centralized architecture and provides a better user experience by incorporating a search mechanism for the files uploaded to the platform. This paper proposes a decentralized platform that allows users to upload educational resources that can be accessed by others and implemented a file meta-data-based search feature to remove the need for users to remember the IPFS hash of a file.
