Taxation, Yield, and Redistribution

The tax system is where map ownership becomes meaningful.

Harberger-style value basis

Each tile has a self-assessed value.

  • Taxes are due on assessed value (rate is influenced by strategic factors).
  • Owners can lower value to attract challengers.
  • Land can be challenged if a better outside bidder appears.

Tax basis and payment basket

Taxes are paid in resources, with basket requirements influenced by neighboring tiles.

  • base mix: certain number of common/uncommon/rare resources
  • local rarity can give discount
  • remote generic resources always valid as fallback, at premium

Redistribution and treasury flow

USDCx enters through:

  • land auctions
  • army auctions (if enabled)

USDCx leaves via weighted distribution to owners based on aggregate assessed value of land.

This creates:

  • incentive to hold high-value productive land
  • pressure to keep valuations honest
  • incentives for active trade and rebalancing

Anti-stagnation goal

Tax must feel like a recurring pulse, not a tax sink where nothing happens.

  • if no one pays, everyone loses value
  • over-assessment increases vulnerability
  • under-assessment reduces own cash flow
