지식재산권에 있어 블록체인 기술 도입에 관한 법적 연구

The application of blockchain technology to the creation of copyright is also meaningful in that the recorded information cannot be changed due to the nature of blockchain and can be used as immutable evidence. If blockchain technology is adopted instead of the current copyright register, the integrity of the information will be stronger due to the nature of the blockchain, and once the use contract is concluded by a smart contract, the subsequent distribution of profits from the implementation and use of intellectual property rights will be automatic. In the context of NFT issuance of works, NFTs have the utility of securing the scarcity and uniqueness of digital content, ensuring and proving asset ownership, high cash flow, access to NFT marketplaces, and returning consideration to digital content creators in secondary distribution transactions. However, issuing authentic works as NFTs without the author's permission may infringe on the copyright holder's right to reproduce or create derivative works. It is also necessary to apply the first sale theory in the case of users who purchase NFT works in the form of transmission. Fractional investment, which has emerged along with the utilisation of blockchain technology, has raised the need for financial regulation beyond the transaction of works.
