Decentralized Trust Management in Web 3.0: A Comprehensive Approach to Network Security

This paper investigates decentralized trust management as a foundational element of Web 3.0, emphasizing a secure, autonomous, and user-driven approach to online interactions without reliance on centralized authorities. We address key challenges in decentralized environments, including those in Decentralized Finance (DeFi), decentralized identity (DID) systems, and Web 3.0 governance models. Our proposed framework integrates blockchain, Proof of Stake (PoS) consensus, Decentralized Identifiers, Zero-Knowledge Proofs (ZKPs), and smart contracts to create a comprehensive, secure, and scalable trust management solution. This method addresses limitations observed in traditional frameworks like X.509 and PGP, which only cover isolated aspects of trust. The results from our approach demonstrate considerable improvements in transaction security, user privacy, and data autonomy, driven by enhanced policy formulation and validation mechanisms. Through a robust trust scoring system and self-executing smart contracts, our solution ensures effective and transparent trust management across diverse Web 3.0 applications. Experimental results indicate that our integrated approach significantly elevates security and efficiency, positioning it as a scalable model for the evolving needs of decentralized networks. This work provides a solid foundation for future Web 3.0 systems, offering a practical and resilient framework for managing trust in decentralized, user-centric ecosystems.
