Описание:

This 'Proof of Visit' project invited users to mint Counterparty tokens to represent being at a specific location in the world.

Instead of postcards or souveniers, this idea aimed to timestamp and 'geostamp' a location of an individual digitally on a cryptographic token to prove the user actually was at a specific location.

These tokens, like KEEPSAKE and PROOFOFVISIT could be collected, sent and even traded.
