Why is Metaverse Standardization Important? The metaverse, where the digital and real worlds converge, was once considered a realm of imagination confined to science fiction. However, it is now increasingly permeating our daily lives. Despite rapid technological advancements, a significant hurdle must be overcome for the metaverse to evolve into a popular and inclusive platform: the problem of 'fragmentation' caused by a lack of standardization. This issue was also a major agenda item at the 'Metaverse Technology Standardization Expert Roundtable' hosted by the Korean Agency for Technology and Standards (KATS) on April 9, 2026. During the event, experts unanimously pointed out that the current metaverse industry is suffering from fragmentation due to the proliferation of diverse platforms and the absence of technical standards. They emphasized that this fragmentation is a primary cause of degraded user experience and delayed expansion of the industry ecosystem. Standardization and interoperability are considered essential elements for the expansion of the metaverse. Within the metaverse, various elements such as avatars, digital assets, and services must interact. However, current platforms emphasize individual user experiences, creating isolated ecosystems. Consequently, users find it difficult to switch between platforms or exchange data, experts noted. Dr. Park Jun-ho, Chairman of the Digital Convergence Standards Forum under the Ministry of Science and ICT, who participated in the roundtable, emphasized, "Unified technical standards and interoperability are essential for avatars, digital assets, and services to move freely and interact within the metaverse." He added, "Discussions on standardization must be accelerated to keep pace with the rapid development of related technologies such as NFTs and blockchain." His remarks suggest that the metaverse ecosystem cannot grow solely based on technological completeness; unified specifications ensuring seamless connections between different platforms and services are crucial. In particular, NFT and blockchain technologies are emerging as core technologies that enable the proof of ownership and trading of digital assets within the metaverse. However, if these technologies are implemented in different ways, users will face the inconvenience of losing or having to repurchase their digital assets every time they switch platforms. This undermines 'continuous digital identity,' one of the metaverse's greatest attractions. Korea's Strengths: Standardization Experience and Technological Infrastructure Chairman Park Jun-ho specifically mentioned that Korea has significant potential to demonstrate global leadership in metaverse technology standards, leveraging its accumulated standardization experience in the telecommunications and semiconductor sectors. In the past, Korea actively participated in international standardization processes in mobile communications, securing technological leadership. This experience can be a valuable asset in the new technological domain of the metaverse. Standardization experience in the telecommunications sector does not merely signify technological superiority. The standardization process requires coordination among various stakeholders, cooperation with international organizations, and the establishment of a long-term industrial vision. Korea possesses the know-how to successfully navigate these complex processes, which serves as a crucial competitive advantage in leading metaverse standardization discussions. Furthermore, its technological prowess in the semiconductor sector is essential for building metaverse infrastructure. As the metaverse is a technology that demands large-scale data processing and real-time rendering, it cannot be implemented without high-performance semiconductors. Korea's accumulated technological capabilities in this field can contribute to securing a substantial voice in metaverse standardization discussions. Specific Standardization Discussions: What to Standardize? During the roundtable, in-depth discussions were held on the specific targets for metaverse standardization. Experts primarily proposed three areas for priority standardization. First is avatar representation methods. Currently, each metaverse platform implements avatars in different ways, causing users the inconvenience of having to create a new avatar every time they switch platforms. Standardizing avatar appearance, movement, and emotional expressions would allow users to maintain a consistent digital identity across multiple platforms. Second is interaction protocols within virtual spaces. In the metaverse, various interactions occur between users, between users and objects, and between objects themselves. If these interactions are implemented differently across platforms, developers would have to create separate content for each platform, leading to increased development costs and hindered innovation. A unified interaction protocol would offe
