Claim a place. Name it. Defend it.

A live map of contested visual claims.

A public canvas for places: control the name and visual layer of a location until someone values the claim enough to buy it.

Why geography is the medium

Geography is finite. Every square meter of the map sits in one place.

A shared map gives people common coordinates. The protocol makes claims on those coordinates legible.

Flags, monuments, borders, street names — humans have always used geography to make meaning visible. merca.earth makes this mechanism digital, global, and protocol-enforced.

Why contestability matters

This protocol does not model permanent exclusion.

On merca.earth, every parcel backs a claim that stays contestable. The current controller can name the parcel and shape its visual layer, but they cannot lock it forever.

That rule is explicit. It shapes the whole system.
