Blockchain technology itself has the characteristics of decentralization, immutability, transparency and traceability, but the application of these characteristics in the field of copyright protection is usually to prevent infringement rather than promote infringement. If you try to use blockchain technology to spread infringing content, not only will it violate technical ethics and legal norms, but you will also face serious legal risks and ethical issues. The following is an objective analysis of blockchain technology and copyright protection： --- ###Legal use of Blockchain in copyright Protection**** 1. **Copyright confirmation and certificate** -The blockchain can record the creation time, author information and modification records of the work, generate a unique hash value, and use it as legally recognized electronic evidence (such as Ant Chain, Tencent Zhixin Chain and other platforms). -For example, a photographer can put the hash value of his work on the chain to prove that he is the original author. 2. **Smart contract and authorization management** -Automate the execution of copyright authorization and revenue distribution through smart contracts to reduce disputes in intermediate links. -The music and film industries can track the use of works through the BLOCKCHAIN to ensure that creators receive a reasonable share. 3. **Infringement traceability and evidence collection** -The transparency of the blockchain can help identify the path of dissemination of infringing content and assist in legal accountability. -For example, after the dissemination record of an infringing video is written to the blockchain, the right holder can quickly locate the source. --- ### Why is BLOCKCHAIN** difficult to use to spread infringing content**? 1. **Legal and technical regulatory constraints** -National laws (such as China's "Cyber Security Law" and the EU's "Digital Single Market Copyright Directive") clearly require platforms to delete infringing content, and blockchain node operators may be held accountable for storing infringing data. -Regulatory agencies can restrict access to infringing content through technical means (such as DNS blocking, node IP blocking). 2. **Storage cost and efficiency issues** -Public chains (such as Ethereum) have extremely high storage costs (1MB of data costs more than a thousand US dollars) and cannot carry a large number of infringing content such as videos and pictures. -Even if distributed storage such as IPFS is used, once the hash value of the infringing content is identified, the node can still be required to delete the local copy through legal means. 3. **Technical ethics and community consensus** -Mainstream blockchain communities (such as Bitcoin and Ethereum) follow the principle of legal compliance, and most developers refuse to support infringement scenarios. -Decentralized networks rely on nodes to participate voluntarily, and the dissemination of infringing content may lead to nodes being legally held accountable, thereby losing network support. --- ###Potential risks and countermeasures of Blockchain technology** 1. **Anonymity and Dark Web abuse** -Although the blockchain address can be anonymous, it is still possible to track the true identity through on-chain data analysis (such as transaction patterns and timestamp associations). -Law enforcement agencies have successfully cracked cases of illegal transactions using cryptocurrencies and blockchains many times. 2. **Limitations of forking and content that cannot be deleted** -Even if infringing content is written to the blockchain, network forks (such as the split of Ethereum, ETC and ETH) may cause the old chain to be deprecated and related content to lose its dissemination value. --- ### Conclusion The core value of blockchain technology lies in building a trust mechanism, not breaking through legal constraints. Using it to disseminate infringing content is technically inefficient, legally risky, and contrary to technical ethics. The global judicial system is strengthening supervision through means such as on-chain evidence collection and cross-border law enforcement collaboration (such as the Interpol Cryptocurrency Crime Working Group). For creators, BLOCKCHAIN should be actively used for copyright protection; for communicators, respect for intellectual property rights is a dual requirement of technology and law. Any attempt to abuse technology will eventually face legal sanctions.
