Abstract
A method and system for linking a physical artifact to a non-fungible token (NFT) with a digital certificate and/or a digital certificate of authenticity (COA) are disclosed herein. The method and system use multiple attestations along with digital ledger technology to provide a digital certificate of authenticity for an object such as a work of art, collectible, or a non-fungible token (NFT) when the NFT is minted. An extended physical backed token (EPBT) is also generated for the physical artifact.
