我们建议使用区块链来实现MPC，它不需要参与方同时在线或相互交互。提供投入但不希望收到产出的缔约方可以在提交一条信息后离线。除了我们的主要结果，我们研究结合通信和状态的复杂性MPC，因为它对我们的主要建设的通信复杂性的影响。最后，我们提供了我们的主协议的一个变体，它还提供了有保证的输出交付。
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 communication complexity of our main construction. Finally, we provide a variation of our main protocol which additionally provides guaranteed output delivery.
