# 1. Abstract

CLEBUS' worldview is a hyper-connected metaverse platform utilizing blockchain technology. This plays a positive role in lowering the entry barrier so that users can easily experience virtual reality and metaverse through the advanced technology developed in-house. Furthermore, various companies, developers, users, etc. build a Metaverse ecosystem that leads to a smooth virtuous cycle among each ecosystem member provided by CLEBUS. The metaverse industry is expected to expand further in the future. According to an analysis by Strategy Analytics, a global market research company, the global Metaverse market size is expected to reach $280 billion (approximately 315 trillion won) by 2025. Metaverse is distributed through the virtual world. It is emerging as a new market where social activities can be carried out as in reality. In other words, it is a more advanced concept than simple virtual reality. It is possible to create value and exchange that occurs in the real world by directly participating in the virtual world beyond just viewing virtual reality on a screen. Meanwhile, behind the spectacular growth of the metaverse market, there is no proof of ownership, lack of an integrated platform for virtual reality and metaverse, and an unreasonable content profit structure. In other words, as the metaverse market grows and the value of goods traded within the market increases, proof of ownership of the item is required. In addition, a proper integrated platform that can bring together virtual reality users and metaverse content is still lacking. In addition, developers can seek profits by utilizing the economic ecosystem formed in the metaverse in addition to profits from content sales, so there must be an abundant supply of attractive content in the market. The CLEBUS team proposes an NFT asset-based Metaverse platform using blockchain technology to address these requirements.
