CityCoins / Miami Voice (legacy but instructive)
Token tied to a city: 30% of mining yield went to the city government's wallet; holders could signal local priorities via the Miami Voice app. NYC briefly launched a NYCCoin variant. Real money flowed to Miami's treasury before the program lost momentum.
Miami vs. NYC: the two cities' tokens publicly competed on mining yield, price, and treasury inflows. An early experiment in city-vs-city token rivalry.
Within Miami, holders voted on which local issues to highlight via Miami Voice; the wallet was held by the city to be spent on Miami-only initiatives.
Even though CityCoins fizzled, the mechanic of (a) city-vs-city token competition and (b) holders voting on local spending is a clean template. Worth cataloging on BelongHub as a 'what tried, what failed, why' case.

Pingo Doce 'Escola Feliz' (Happy School)
Pingo Doce supermarket program: shoppers earn 'cromos' (tokens) per €20 spent via the loyalty app, with bonus cromos for fruit/veg purchases. Cromos are donated to schools, which exchange accumulated points for tech/sports/art equipment (tablets, robotics kits, projectors). Covers 1,000+ schools across Lisbon district.
Cabin. Neighborhoods, Outposts & ₡ABIN votes
Cabin built a directory where coliving properties register as Outposts (informal listings) and can be promoted to official 'Neighborhoods' once they meet criteria (≥4 bedrooms, 20mbps) and accumulate 1,000 ₡ABIN votes from the community. The token treasury was distributed when the DAO wound down in 2025, but the directory and the Neighborhood/Outpost framework remain.
+Colonia (Más Colonia). Uruguay city DAO
Spanish-language city-DAO project in Colonia, Uruguay. Property purchase grants a governance token; residents vote on district-level decisions (budgets, public works) using a token-weighted system. Pitched as a hybrid of physical real-estate ownership and on-chain neighborhood governance.
