Privacy-Preserving Smart Contracts

  • Ranjit Kumaresan | MIT

Cryptographic technologies such as encryption and authentication provide stability to modern electronic commerce. Recent technologies such as Bitcoin have the potential to further enhance the way we conduct electronic commerce. In this talk, I will describe a recent line of work that develops a robust theory of privacy-preserving contracts that are self-enforcing and do not require third-party intervention. Starting from Bitcoin-inspired abstractions, the theory enables building provably secure and scalable applications on top of cryptocurrencies.
