What is authorization card?

IP3 innovatively converts the legal connotation contained in "copyright license" to NFT, creating a new type of NFT "NFT-CD authorization card". The issuance of the authorization card and the authorization to license the derivative will be recorded by the NFT authorization agreement. This record can be viewed on the chain at any time to indicate the authorization and license relationship between the derivative and the original work. Each authorization card here represents a "copyright license", and the license holder has the right of reproduction, exhibition, information network dissemination, adaptation, compilation, etc. In short, it can be used for commercial purposes or for Make derivatives.
