Construction of an Online Shopping Platform Based on DApp

Shopping platform increases service speed and reduces transaction cost. However, it also leads to issues of information asymmetry. Some sellers fabricate the price of promotional goods prior to promotion, not only affecting the reputation of sellers, but also viciously influencing the goodwill of the shopping websites. On this basis, a shopping decentralized Application (DApp) based on blockchain technology was designed; this research integrates the blockchain and shopping App. The App used the decentralized technology of distributed blockchain tamper resistance and its advantages of distributed ledger, decentralization, traceability, smart contract, and information tamper-proof to reduce the adverse impact of information asymmetry on consumers.
