Title:
Blockchains Enable Non-Interactive MPC
Authors: Vipul Goyal, Elisaweta Masserova, Bryan Parno, Yifan Song
Abstract:We propose to use blockchains to achieve MPC which does not require the participating parties to be online simultaneously or interact with each other. Parties who contribute inputs but do not wish to receive outputs can go offline after submitting a single message. In addition to our main result, we study combined communication- and state-complexity in MPC, as it has implications for the efficiency of our main construction. Finally, we provide a variation of our main protocol which additionally provides guaranteed output delivery.
