Can Quadratic Voting Be Applied to Decisions beyond Funding, Such as Protocol Upgrades?

Yes, quadratic voting can be applied to any governance decision, including protocol upgrades, parameter changes, and strategic direction. While its most famous application is funding public goods, the core principle of non-linear cost to influence can be used to make any collective decision more representative.

For example, voters could allocate their fixed budget of "influence points" across a set of competing protocol upgrade proposals.
