The BTSc Platform started as an ecosystem platform for the culture and arts industry, encompassing music, movies, and dramas. Through continuous research and development, the entertainment ecosystem has now been implemented on Metaverse, known as JFLEX WORLD. BTSc has established an entertainment ecosystem within Metaverse, offering a range of services from concerts to personal broadcasts. Additionally, a dedicated market for trading various contents as NFTs will be created. BTSc aims to systematize the entire culture and arts industry on the blockchain, distributing content value through the NFT market. The integration of Metaverse and NFT will make BTSc Metaverse an independent entertainment platform.
