There are mainly two issues in the recognition process, which is the right of a digital musical work. One is that there is a difficulty in recognizing the right of a work that enjoys copyright, but there is no way to find the copyright subject. The reason is that since most users do not adopt the real-name system on internet platforms, there is no way to know who the real rights holder of the work is after the work has been traded on the Internet several times. Also, due to the huge number of works and complicated sales routes in the digital platform music production transaction process, the phenomenon of the last right holder is not clear. After the copyright registration of works to which the blockchain is applied is completed, the blockchain automatically creates two important data: time and hashtag. Users can track any copyright transaction records on the block chain based on hashtags and the situation at the time, so that the source of copyright is identified and realized. In addition, by using blockchain, it is possible to effectively solve the problem of double payment and reliability improvement in digital copyright transactions. The difficult-to-change data of blockchain technology effectively guarantees the authenticity of blockchain information. However, the blockchain technology platform has no way of determining whether or not it should satisfy the creativity needs when modifying a blockchain work. Also, there is no way to prove that you are the original creator. The blockchain platform can only guarantee the proof power of the blockchain, and there is no way to prove the trust of the creator and the work before the blockchain. For this reason, there is a problem of whether it is appropriate to recognize a work by applying a block chain, and there are limitations in who is the true subject of rights. Since the development of blockchain technology is still in its infancy, there are many technical problems in safety, operation sharing, and transaction efficiency. There is also no detailed explanation on how to improve the evidence validity of the blockchain. There is also a lack of industry technical standards. A detailed analysis is also required on whether the court has adopted the relevant evidence. For this reason, more and more scholars are proposing the implicit accreditation method. They argue that it is desirable to realize a balance between the creation, promotion, broadcasting, and use of digital music works, taking into account the interests of intellectual property rights and income management of the rights holders of digital music copyrights in China. Under the identity privacy protection model, a cell that has not undergone any delegation cannot acquire user identity information through data released by the blockchain. Also, it is not possible to track users and personal identities through IT technologies such as Internet eavesdropping and streaming analysis. That is, a significant failure occurs in reliable operation. The reason why a contract based on blockchain limits the rational use of copyright is that the demand for professional technology is high and the parties autonomy is limited. In addition, there is a lack of professional review and supervision. Regarding the right holder of the work, if there is a violation of rights or a fraudulent circumstance in the formal clause of the smart contract, the right holder faces information asymmetry. Due to the lack of review and supervision by a neutral third party, it will inevitably face serious challenges in how to guarantee equal contract rights.
