Ensuring Resilient Voting: Mitigating Sybil Attacks and Voter Abstention

The core message of this article is to develop voting rules that are resilient to sybil attacks and voter abstention, by using the status-quo as an anchor of resilience. The authors characterize the tradeoff between safety (the inability of sybils or abstentions to change the status quo against the will of the genuine agents) and liveness (the ability of the genuine agents to change the status quo), and show that the Status-Quo Enforcing voting rules are often optimal.
