The culture and arts industry for the overall art industry, including music, movies, and dramas, was the first part of the platform. Since then, continuous platform research and development has been carried out, and the entertainment ecosystem has finally been implemented on Metaverse, and the BTSc Metaverse World has been opened under the name JFLEX WORLD. Expanding services that can be implemented through Metaverse from concerts to personal broadcasts are just some of the things that can be done with the entertainment ecosystem established by BTSc. We plan to create a dedicated market where contents generated within the platform can be traded in the form of NFT. The Metaverse platform that is user-led on the Blockchain is called BTSc. We want to get out of the simple business ofCryptocurrencies and systematize the entire culture and arts industry on the basis of this. We will use the NFT market to distribute the value of content. The safest way to protect copyrights is NFT distribution. NFT and Metaverse are not separate businesses. It means building a service that can be implemented on Metaverse.
