Judicial recognition of blockchain-based copyright registration, such as Po.et, is emerging. In China, the Hangzhou Internet Court (2018) recognized blockchain-stored electronic evidence as admissible, affirming its authenticity and integrity in a copyright dispute (Huatai Yimei v. Daotong). The court established a procedural test for blockchain evidence, leveraging its immutability. Similarly, Chinese courts have explored Po.et-like systems for digital copyright, ensuring reliable data across generation and verification stages. Despite challenges like legal lag and platform credibility, these cases highlight blockchain’s potential for transparent, tamper-proof copyright registration. Globally, jurisdictions are cautiously embracing blockchain evidence, with Po.et’s decentralized approach promising enhanced judicial credibility for copyright protection, though regulatory frameworks remain in development.
