The decimals generated by the geohashing algorithm can also be used to generate a single point on the globe instead of one for each graticule and this award celebrates those lucky or mad enough to pursue that single point.
To generate this point take W30 decimals for a date (to make it global) and multiply the latitude by 180 and subtract 90, and the longitude by 360 subtracting 180. This will generate a single point on the globe which is today's only globalhash.
Proof is the same as any hash, but at the single day's coordinates. Good luck! The odds of the globalhash falling in your graticule are 1 in 64,800!
Example
On September 5th, the W30 decimals generated were 0.1991464 and 0.9440844 for latitude and longitude respectively.
0.752868489396019 * 180 = 135.5163280912834 - 90 = 45.5163280912834° Latitude 0.767821600853908 * 360 = 276.4157763074069 - 180 = 96.4157763074069° Longitude
Or 45.5163280912834° N, 96.4157763074069° E which is in a mountainous region of Mongolia.
Winners
The following Geohashers have won this award, and have supplied proof.
