Abstract:

Elections providepeople with the opportunity to express their opinions in the collectivedecision making process. However, the existing (election) voting  systemshave many limitations and often fail to serve the best interest of the people.In this talk, I will introduce a new concept called “statement voting”: insteadof defining a fixed election candidate and determining the vote in the votingphase (as in conventional voting schemes), each voter can define a statement inhis or her ballot in the voting phase, and then the statement will determinethe vote in the tally phase. Statement voting allows us to develop alternativedecision making models to make better use of ``the wisdom of crowds''. As animmediate application, based on statement voting, we design the first efficientliquid democracy e-voting scheme. This is joint work with Bingsheng Zhang.
