It is almost impossible to share copyrighted content through a distributed network architecture without leaving any digital traces. The distributed network architecture itself cannot change the illegality of copyright infringement and the nature of leaving digital traces. In a network environment, the transmission and interaction of data will leave records in many links, including the logs of network service providers, device information, IP addresses, etc. Even with a distributed network, these related information may be traced. Copyright protection is intended to ensure the legitimate rights and interests of content creators. Unauthorized sharing of copyrighted content is an infringement and will face legal liability. In addition, with the continuous development of technical means, law enforcement agencies and copyright owners have many ways to track and discover infringements, and it is difficult to achieve complete tracelessness.
