Abstract: A blockchain method employing a geometry token, a polygon storage method, an electronic device, and a computer-readable storage medium. A blockchain token comprises geometry data. The geometry token is circulated by means of transferring, splitting, and merging. When a geometry is a land parcel in the form of a polygon and represented by geographic location information, the geometry is a blockchain suitable for recording circulation of land rights. Except for a token representing an initial polygon geometry, polygon geometries in all tokens in the blockchain are generated by transferring, splitting, or merging other tokens. Therefore, a polygon in each unused token in the blockchain is unique and exclusive. When the initial polygon of the blockchain used to record land circulation represents the entire surface of the earth, the blockchain can be used to record land circulation around the world.
