Decentralized Social Network

Abstract

The work is devoted to the analysis of technologies and the design of a responsive social network application with elements of decentralization. Despite all the positives that social networks bring, we can’t forget the potential problems associated with their use. Some of the problems can be minimized by using decentralization, which has the effect of limiting third-party control.The centralized part is created using the Vue.js and Laravel frameworks, which provide basic functions. In the context of decentralization, is very important the creation of a smart contract that is stored in the Ethereum blockchain. By using the Web3.js library, it is possible with a smart contract and a MetaMask wallet to carry out the transactions necessary for storing data on the blockchain.To increase efficiency, the IPFS distributed file system is used, which offers storage of larger files or texts and generates their content, while it is possible to access this data. By decentralizing these functions, data immutability is achieved, censorship is excluded, and data security is also provided.
