Movieschain: avaliação de filmes com blockchain

Abstract

Current film review platforms face several challenges related to manipulation, lack of transparency, and targeted hate practices such as review bombing, which undermine the credibility of these systems. In response to this scenario, the development of Movi- esChain is proposed — a film review system based on blockchain and smart contracts. The goal is to ensure the uniqueness and transparency of reviews while enabling pu- blic auditing carried out by the users themselves. The research adopts a qualitative and exploratory approach, with theoretical foundations on centralized review platforms, blockchain, and related systems. The development follows software engineering princi- ples, including requirements gathering, use case design, and class modeling. The ap- plication was built with a Java-based back-end, Vue.js front-end, and smart contracts deployed on the Ethereum Sepolia blockchain. The results demonstrate the technical feasibility of a decentralized film review platform, highlight its limitations, and suggest improvements for future work.
