How Is Quadratic Funding Different from Quadratic Voting?

Quadratic funding (QF) is a mechanism for allocating public goods funding, where the total grant to a project is a function of the square of the sum of the square roots of individual contributions. It aims to match small donations from many people with a large pool of funds, maximizing the influence of the number of unique contributors over the amount contributed.

Quadratic voting (QV) is for making governance decisions, where the cost of a vote is the square of the votes cast.
