A copyright trade and protection portal using blockchain technology went online in Shanghai, the first of its kind in China, people.cn reported on May 26.

The online platform can give each item publicized on it a "digital DNA", which records the information of its creator, owner and release time, in addition to the content itself. Content authenticated with the technology can be promoted for commercial use or free sharing. The data cannot be damaged or falsified, according to its operator, a local IT startup company called Yuanben.
