Why Quadratic Voting Is the Only Democratic Model for Pop-Up Cities

One-person-one-vote fails at scale because it incentivizes Sybil attacks and voter apathy. In a digital city, creating fake identities is trivial, making simple majorities vulnerable to manipulation by well-resourced actors.

Quadratic Voting (QV) is the antidote to plutocracy. It forces participants to express the intensity of their preferences, making it economically prohibitive for a single entity to dominate outcomes, unlike the plutocratic models seen in many DAOs.

The model aligns with network effects. As a city grows, QV's cost-curve ensures governance power decentralizes, preventing the stagnation seen in legacy systems like shareholder votes or token-weighted governance.

Evidence: Gitcoin Grants used QV to allocate over $50M in public goods funding, demonstrating its resilience against whale dominance and its capacity to surface community-preferred outcomes.

One-token-one-vote is plutocracy. This model directly maps financial stake to political power, ensuring the largest token holders control all governance outcomes, from treasury allocations to protocol upgrades.

Quadratic Voting (QV) is the antidote. It prices votes quadratically, making it exponentially expensive for a single entity to dominate. This forces whales to build coalitions and surfaces the true intensity of community preference.

QV prevents Sybil attacks. Unlike simple one-person-one-vote, QV's cost curve makes large-scale vote-buying economically prohibitive. Systems like Gitcoin Grants use QV to fund public goods precisely because it resists manipulation.

Evidence: In a 2023 simulation by Radicle, a QV model for a DAO treasury reduced the voting power of the top 1% of holders from 45% under 1T1V to under 15%, radically flattening the power distribution.

One-dollar-one-vote is plutocracy. Linear voting models, used by most DAOs like Uniswap or Compound, allow capital concentration to dictate outcomes. This creates governance capture, not collective intelligence.

Quadratic voting scales power sub-linearly. The cost to buy n votes scales as n², making vote-buying economically irrational beyond a few units. This protects against Sybil attacks and whale dominance.

The cost-curve is the defense. Unlike reputation-based systems like SourceCred, the mathematical guarantee of quadratic pricing enforces fairness without a central arbiter. It aligns cost with marginal social impact.

Evidence: Gitcoin Grants used quadratic funding to allocate over $50M, demonstrating that small donors collectively outweigh a single large donor. The cost to manipulate outcomes became prohibitive.

Collusion is the primary failure mode. QV's cost function assumes independent actors, but real-world participants form coalitions. Sybil-resistant identity systems like Proof of Personhood (Worldcoin, BrightID) are prerequisites, not optional features.

Complexity creates user friction. Explaining marginal cost to a non-technical user is a UX nightmare. Projects must abstract this via intent-based interfaces, similar to how UniswapX abstracts MEV for swappers.

The cost calibration is brittle. Setting the correct price constant for votes is a governance nightmare. Misconfiguration leads to plutocracy or apathy. This requires continuous on-chain metrics and adaptation, a la MakerDAO's PSM adjustments.

Evidence: Gitcoin Grants' early rounds demonstrated clear collusion rings, forcing a pivot towards more sophisticated sybil detection and a move from pure QV to a curated model.
