Proposta de dissertação do MEI Título: Blockchain-based storage with SGX clients for mobile games Proponente(s): Nuno Preguiça Créditos: 42 ECTS Área científica: Computer Systems and Networks Início preferencial: Qualquer semestre URL: Já estão em curso trabalhos preliminares executados pelo alunos: Breve descrição: In the last few years, some multi-user games with a very large number of users have become popular (e.g. PokemonGo). This massive-scale games are hard to support using a centralized architecture. In this work we will design a solution that allows mobile clients to share information, by communicating directly while enforcing strong guarantees -- e.g. for supporting the wallet of users, allowing them to make transactions with other users. To this end, we intend to design a blockchain-based system, where clients run secure hardware (such as Intel SGX) -- by making stronger assumption on the client, we expect to simplify the core algorithms. Observações: This work may be supported by a scholarship from SAMOA project and it is integrated in LightKone project.
