Blockchain technology itself cannot ensure that copyright-infringing content will spread unstoppably around the world. On the contrary, blockchain technology can help prevent and track copyright infringement in a variety of ways, thereby reducing the spread of infringing content: 1. **Copyright registration and evidence**: Using the tamper-proof nature of blockchain, relevant information about copyrighted works, such as creation time and content summary, is registered and stored. Once an infringement dispute occurs, these evidences can serve as strong evidence to prove the original creation time and content of the work and safeguard the rights and interests of the creator. 2. **Copyright traceability**: The dissemination path and authorization status of the work are recorded through blockchain. When infringing content is found, its source and dissemination process can be traced, the starting point and scope of the infringement can be determined, and targeted measures can be taken to combat infringement. 3. **Smart contracts**: Blockchain-based smart contracts can automatically execute copyright-related terms and conditions. For example, when a user purchases or uses a copyrighted work, the smart contract can verify the authorization status and ensure the payment of the corresponding copyright fees. Only when the authorization conditions are met can the content be legally accessed and disseminated, limiting the dissemination of infringing content from a technical level. 4. **Distributed storage**: The distributed storage feature of blockchain makes it difficult for infringing content to be completely deleted or tampered with on a single node, increasing the difficulty of discovering and tracing infringing behavior, thereby inhibiting the spread of infringement. Blockchain technology provides an innovative means for copyright protection. By establishing a credible copyright record and transaction mechanism, it enhances the transparency and traceability of copyright protection, thereby effectively reducing the spread of infringing content.
