Secure Multiparty Protocols on Blockchain
Secure multiparty computation is a significant field of cryptography. It allows for the creation of a protocol that maintains privacy of the inputs and ensures that violation of the protocol results in no benefit to the violator or detriment to an honest party. These protocols can be used in many fields. We examine these protocols in the context of fair exchange with cryptocurrencies, peer-to-peer lending, healthcare, and electronic voting. In all these areas, honesty of execution and fairness in the outcome should be assured, especially if the other parties are not trusted.
