With the development of the information age, more and more digital contents are released to the internet by creators, and the knowledge contents are shared and created in a free or paid manner. Digital contents such as pictures, articles, audios and videos are easy to copy and copy, so that the copyright of an author and information abuse are difficult to protect well. The traditional centralized e-commerce platform is difficult to carry out compliance detection on commodity data, is easy to have the problem of commodity piracy infringement and is difficult to trace. In addition, the traditional centralized e-commerce platform is often provided by a business. Some private data, such as transaction data, payment data, browsing habits, etc., are also held by the one enterprise, and thus have trust issues. In addition, the traditional centralized e-commerce platform often records the use habits of users, browsing records and the like as recommended purposes. The functions meet the personalized requirements of users, and meanwhile, the risk of personal information leakage exists.
Web3.0 was proposed by Gavin Wood, a co-founder in etherhouses in 2014, represents the next generation of decentralized internet and confers individual value. Web3.0 focuses on the value of the relationship "who created, who owns" formed by decentralized techniques such as blockchains. Web3.0 is based on blockchain implementation and naturally has the property of decentralization. At the same time, the user has full authority control over the value of the created data. Each step of a person's action on the internet, each trace, is recorded, quantified, and added to the data value chain.
The embodiment of the specification realizes a decentralized e-commerce platform through a blockchain on the basis of a Web3.0 technology. The method solves the problems of compliance, trust and the like of the traditional centralized e-commerce platform.
