Quadratic voting is a funding mechanism that allows voters to spend more on the causes they really care about without giving too much power to whoever has the largest coinpurse.
- seems like a blend between “one person one vote” and “one dollar one vote” (aka most important person most important vote)
- puts diminishing returns on large investment/influence
- pretty much applies a square root function to your ROI
- for quadratic funding, we essentially naturally adjust the cost / outcomes to reflect the utility for all parties
The quadratic funding mechanism adds a subsidy to compensate for this effect, determining how much Alice “would have” contributed if she also took into account the benefit her contribution brings to Bob.
- one issue I can think of is identity resolution / identity fraud. what’s stopping me from making a ton of accounts to take advantage of initial costs? basically smurfing the system
