The technology relates to linking virtual assets and physical assets through non-fungible tokens (NFTs) in a metaverse. As such, the invention anchors a metaverse to the real world. The metaverse can limit ownership or rendering of certain virtual assets in the metaverse to only those who actually own physical assets. For example, the metaverse can limit a virtual representation of a car in the metaverse to those who own the real car. The linkage between the virtual and real assets can be verified in the metaverse based on NFTs stored on a blockchain. As such, only those who actually own a physical asset in the real world are associated with the virtual asset (or related representation) in the metaverse.
