Abstract
Despite the ambitious vision of re-decentralizing the Web as we know it, the Web3 movement is facing many hurdles of centralization which seem insurmountable in the near future, and the security implications of centralization remain largely unexplored. Using non-fungible tokens (NFTs) as a case study, we conduct a systematic analysis of the threats posed by centralized entities in the current Web3 ecosystem. Our findings are concerning: almost every interaction between a user and a centralized entity can be exploited to hijack NFTs or cryptocurrencies from the user, through network attacks practical today. We show that many big players in the ecosystem are vulnerable to such attacks, placing large financial investments at risk. Our study is a starting point to study the pervasive centralization issues in the shifting Web3 landscape. © 2024, International Financial Cryptography Association.
