Enigma: Decentralized Computation Platform with Guaranteed Privacy 论文

摘要

A peer-to-peer network, enabling different parties to jointly store and run computations on data while keeping the data completely private.Enigma's computational model is based on a highly optimized version of secure multi-party computation, guaranteed by a verifiable secret-sharing scheme.For storage, we use a modified distributed hashtable for holding secret-shared data.An external blockchain is utilized as the controller of the network, manages access control, identities and serves as a tamper-proof log of events.Security deposits and fees incentivize operation, correctness and fairness of the system.Similar to Bitcoin, Enigma removes the need for a trusted third party, enabling autonomous control of personal data.For the first time, users are able to share their data with cryptographic guarantees regarding their privacy.
