marketplaces such as opensea (opensea.io) or foundation (foundation.app) stores all user details, NFTs and any associated transactions on their platform. Other platforms like wallet providers and exchanges also have 'centralized' control on users. The inefficiencies in the current Web3 architecture is causing the inevitable centralization in the decentralized Web3 world [16]. This can create any of the Web 2.0 related issues such as fraud, ownership issues, and centralized control of users. Moreover, most of the DeFi platforms allow users for decentralized transactions and apply a platform fee and perform their centralized control. While the underlying principles are strongly decentralized, each of these eCommerce initiatives still show a varying degree of centralized control and can be resolved only with platforms with total decentralized user networks being created (that can identify users without the requirement of a centralized agency).
