# Quadratic voting
|
|
|
|

|
|
|
+Quadratic voting (QV) is a decision-making mechanism that allows voters to pay money or other credits to express their priorities. The more credits a voter applies to a given option, the less each credit counts, according to a quadratic decay function.
|
|
|
+
|
|
|
+The QV proposals involve several mechanisms to adjust for the power of wealth concentrations, such as distributing credits equally or redistributing the proceeds of credit contributions for future ballots.

|
+**Input:** ballot of options, weight (e.g., money or pre-assigned credits)
|
|
|
+
|
|
|
+**Output:** weighted outcome

|
+## Background
|
|
|
+
|
|
|
+Quadratic voting was first proposed by Steven Lalley and E. Glen Weyl in 2012 and has been developed in several publications since. It has been widely discussed especially among people involved in blockchain protocol design. The concept is patented by Weyl and collaborators through the company Collective Decision Engines.

+### Sensitivities
|
|
|
+
|
|
|
+* Reflecting degrees of preference
|
|
|
+* Dampening influence of excessive wealth

|
|
+### Oversights
|
|
|
+
|
|
|
+* Deliberation processes
|
|
|
+* Preferences of less credit-endowed participants, under certain implementations
