Multi-party computation (MPC) is a crucial component of decentralized privacy-preserving computational frameworks. It allows for secure sharing of data between parties without leaking any private information. Enigma’s optimized version of secure multi-party computation is one of the promising approaches in this field. It removes the need for a trusted intermediary and offers a more decentralized solution to privacy-preserving computation. The present and future of privacy-preserving computation in fog lies in the development of more advanced and efficient MPC techniques.
