Geoyuan Whitepaper
v1.0 · Updated Sep 2026
1. What is Geoyuan
Geoyuan is a cultural digital asset platform that anchors geographic locations to blockchain identities. Each Geoyuan card binds a photograph and a unique geographic coordinate, then anchors to Base mainnet as a globally unique on-chain entity. It is both a digital collectible and a permanent record of your connection to the world.
