A geohash encodes geographic location into a short string of letters and digits stored on chain. Images and places are intentionally omitted for others to interpret and incorporate. Geohashes Genesis contain 1,251 of the original 4 character geohashes and represent a block roughly 39.1km × 19.5km. The contract mint is closed. These are all 1:1 and rarity depends on how you value location. They can be mapped to Earth or any coordinate system. For instance u09t is a geohash that contains Paris, France.
