The Celeb NFTs service of BerryStore 4.0 was developed to resolve the challenges of the traditional digital goods-oriented NFT market. Due to the nature of digital products, they were nothing but useless products that could not be used in reality other than P2P investment, but BerryStore Celeb NFT is the only real-based service linked to the unique goods of global influencer and blockchain system, including Korean wave celebrities. Therefore, it is a solution that can prove the authenticity of the product and solve problems such as the useless of the product. In addition, our own NFT product is characterized by issuing authentication through real products and minting of cryptocurrency. In the future, owners of authentication and products can easily transfer their rights through authentication confirmation to sell to other users in off-line.
