Proof of originality of intellectual property rights. The original author information, the content information of the work, the creation time information and the original dissemination information of the patent and the cultural product are encrypted and uploaded to the blockchain, and the attribution of the copyright, trademark and patent right is clarified; 2. The intellectual property exchange certificate. Uploading intellectual property creator information, property rights acquirer information, and transfer time and method to the blockchain can effectively reduce IP transaction procedures and reduce transaction costs; 3. Evidence of intellectual property rights protection.
