Dentsu Innovation Initiative (DII), an internal organization of the Dentsu Group Inc., that promotes R&D under the Dentsu Japan Network, which supervises and supports Japan business operations of the Group, has developed an NFT (Non-Fungible Token: digital data with a statement of certification or owner certificate that cannot be falsified) establishment support service for content holders in the entertainment and sports fields in collaboration with Startbahn, Inc., and Dentsu Inc. This service will be available starting from immediately from both Startbahn and Dentsu. Many NFT markets (market places) and related businesses have rapidly been launched because NFT has gotten attention as it allows, by tying NFT and content data, the creation of a mechanism that can certify holders of content of artwork or entertainment work and that can return profits from every secondary or tertiary transaction to copyright holders (producers and artists) in the digital field where copying and falsification are easy because NFT can be constructed on a blockchain and cannot be falsified. However, there are problems, such as the marketplace of one company not compatible with that of another and initial information and setting rules not being handed over. To resolve these problems and to make services using NFT really beneficial for IP holders, creators, and fans of content, especially of entertainment and sports, it is necessary to ensure the uniqueness of digital data and to realize the handover and distribution of information about content, such as the setting of money to be returned, terms of use, and publisher, across operators. To make this come true, this service has been developed in cooperation with the three companies. Startbahn is strong in the NFT base that makes secondary distribution management possible across operators. The blockchain and back-end system the company provides to start the NFT business constitute the core of this service. By combining this with Dentsu s content, expertise in creative and planning that deeply understand fans mentalities, and business network, the services necessary for establishing the NFT business are provided to all content IP holders at once. The services include the formulation of an NFT issuance and sales strategy, UI/UX design, and the planning and development of backend system and an interface necessary for issuance and sale of NFT. This prevents utilities, such as special experiences and rights that can be gained by possessing NFT, from being limited to within the services of a company and realizes new fan experiences that only NFT can bring about.
