Enabling Technologies for Web 3.0: A Comprehensive Survey

TL;DR

This survey analyzes enabling technologies for Web 3.0, outlining a five-layer architecture and the roles of IoT, 5G, blockchain, semantic web, and 3D web in enabling decentralized, privacy-preserving, and intelligent Internet services. It synthesizes current standards (W3C, IPFS, Solid, Polkadot) and industry deployments, and details how DApps, DeFi, DAOs, NFTs, decentralized identity, and the Metaverse can be realized through integrated technologies. The paper surveys recent research on interoperable IoT networks, edge/blockchain paradigms, semantic web trajectories, 3D web frameworks, and security/privacy challenges, highlighting actionable frameworks like Triastore, WoT, RDF/OWL, SPARQL, and WebXR. By identifying open issues and emerging technologies (Wasm, quantum computing, ZKPs, Generative AI), the work outlines practical research directions and potential impact on Web 3.0 adoption and scalability.

Abstract

Web 3.0 represents the next stage of Internet evolution, aiming to empower users with increased autonomy, efficiency, quality, security, and privacy. This evolution can potentially democratize content access by utilizing the latest developments in enabling technologies. In this paper, we conduct an in-depth survey of enabling technologies in the context of Web 3.0, such as blockchain, semantic web, 3D interactive web, Metaverse, Virtual reality/Augmented reality, Internet of Things technology, and their roles in shaping Web 3.0. We commence by providing a comprehensive background of Web 3.0, including its concept, basic architecture, potential applications, and industry adoption. Subsequently, we examine recent breakthroughs in IoT, 5G, and blockchain technologies that are pivotal to Web 3.0 development. Following that, other enabling technologies, including AI, semantic web, and 3D interactive web, are discussed. Utilizing these technologies can effectively address the critical challenges in realizing Web 3.0, such as ensuring decentralized identity, platform interoperability, data transparency, reducing latency, and enhancing the system's scalability. Finally, we highlight significant challenges associated with Web 3.0 implementation, emphasizing potential solutions and providing insights into future research directions in this field.

The data is communicated from the physical layer to the application layer through intermediate layers, i.e., the communication layer, network layer, and semantic layer. Each layer can be realized by corresponding technologies that are IoT, 5G, blockchain, semantic web, and 3D interactive web technologies.

The architecture hinges on key components: Things, encompassing physical and virtual entities, detailed by Thing Descriptions that standardize capabilities and interactions. The Thing Directory facilitates efficient discovery and access to Things through URIs. SPARQL enhances querying capabilities, while the JSON-LD data format ensures interoperability and semantic understanding.
