Towards secure quadratic voting

We provide an overview of some of the security issues involved in securely implementing Lalley and Weyl’s “Quadratic Voting” (Lalley and Weyl, Quadratic voting, 2016 ), and suggest some possible implementation architectures. Our proposals blend end-to-end verifiable voting methods with anonymous payments. We also consider new refund rules for quadratic voting, such as a “lottery” method.
