Abstract:
Improving efficiency and performance is an important topic in the world today. As it is
well-known, cooperative computing is an effective and traditional approach, and it is widely
used in various fields. Inspired by this idea, take E- commerce for example, Security is one
of its important indicators. In E-commerce, the security technology has become a major issue
restricting the rapid development and popularization of E- commerce.With the advent of new
technologies, Blockchain plays a major role in ecommerce sector.With the characteristics of
decentralization, persistency, anonymity and auditability, blockchain technology is a new tool
to solve the product traceability, information security and privacy, payment efficiency and cost
reduction in cross- border e-business.Existing E-commerce models are trapped in a dilemma
between the proof of ownership and privacy protection. To address this issue,We have made a
platform Shoppingverse which is a blockchain based ecommerce.we design a privacy-preserving
business protocol by employing private smart contracts in the negotiation phase. The protocol
allows counterparties make deals without the disclosure of private information such as identities,
addresses, and phone numbers. Moreover, we employ the zero- knowledge proof to guarantee
the ownership.
