The Future of Digital Authentication: Blockchain-driven Decentralized Authentication in Web 3.0

This paper presents an innovative Web 3.0 authentication technique, designed for a user-centric internet environment. Addressing the rising demand for authentication techniques suitable for Web 3.0, it defines the essential features of such systems and introduces a new approach using smart contracts. This approach utilizes mother and child tokens in conjunction with the lock smart contract to ensure secure authentication. The approach is thoroughly tested against various security threats, including man-in-the-middle, replay, and brute-force attacks, and its practicality is evaluated on Ethereum-based networks.
