Product information

Enterprises can digitize high value products through blockchain technology, and provide consumers with a series of blockchain-enabled derivative services, including the transfer of ownership of goods such as auctions and gifts. At this point, you need to use NFT. 

NFT are non-fungible tokens provided by VeChain ToolChain^TM platform for end users to manage non-fungible assets. Each physical product will be associated with an  NFT.
