Moreover, our system will certify all artworks on our platform without exception as authentic (Primary and Secondary Market) and will prevent the creation of artworks duplicates, ensuring that the supply issued by the artists is respected, whether on our marketplace or competing marketplaces, thus preserving the value of the works. Our Proof of Authenticity will also protect the digital artwork of NFTs with a tracking system that combats the sale of potential counterfeits on platforms and competing products that would allow the display or sale of illicit works. Our system will make the Opus ecosystem healthy and completely secure, whether for our artists or buyers on our marketplace, and preserve the value of its artworks. The combination of the blockchain and our Proof of Authenticity technology will allow us to authenticate the works of the artists and the NFTs linked to these works, giving us a final product with complete and flawless authenticity. To complete, we needed a third element to enhance our authenticity system. --- # Agent Instructions This documentation is published with GitBook.
