This paper introduces a user authentication technique that utilizes a dynamic SoulBound Token (SBT) to tackle challenges associated with the oracle problem in decentralized environments. The approach uses dual smart contracts – local and global – along with blockchain tokens, removing the need for intermediary verification processes. The proposed method improves security by allowing users direct control over their authentication data, thus mitigating risks associated with centralized authorities and man-in-the-middle attacks. The feasibility and efficacy of this approach are demonstrated through a location-based prototype, indicating significant potential for application in Web 3.0 ecosystems. This paper also provides a comprehensive security analysis, underscoring the robustness of the proposed system against cyber threats.
