디지털 가상세계에서의NFT저작권 쟁점에 관한 검토

With the development of metaverse platforms, non-fungible tokens (NFTs), a new technology that can prove ownership of digital files in the virtual world, are attracting attention. NFTs span gaming, art, and culture, and serve as a new channel for digital creators to reach customers. NFTs permanently store digital file ownership records and transaction records on the blockchain. NFTs have grown rapidly based on their uniqueness, the increase in cryptocurrency trading volume, and the development of blockchain technology. NFTs based on blockchain technology are being utilized in combination with the virtual world of the metaverse in that they facilitate proof of ownership of digital creations due to their non-fungible nature. By enabling users to trade 'assets' in the metaverse using NFT, it is possible to create an independent economic ecosystem, and by enabling the 'cashing' of digital currency according to asset transactions using NFT, the virtual world of the metaverse can be connected to the real world. In this case, there is a possibility that a person other than the creator arbitrarily pre-registers the creation as an NFT and claims the ownership, or the NFT ownership of a secondary work such as a parody work infringes on the rights of the original work, resulting in copyright protection issues. In addition to the above traditional copyright-related issues, new copyright issues that were not previously anticipated due to the nature of NFTs based on blockchain technology are emerging, so it is necessary to examine various copyright law issues raised by NFT. The main content will be whether the concepts that have been applied to the existing copyright law, such as whether the objectivity of NFT can be recognized in traditional jurisprudence, the issue of the distinction between ownership and copyright, digital ownership and the right of subsidy, and whether the principle of exhaustion of rights can be applied in the same way to the metaverse and NFT.
