An Ecosystem Approach to Web3.0: A Systematic Review and Research Agenda

Abstract

Purpose

This paper reviews existing research on Web3.0 published between 2003 and 2022, identifying key themes and future directions from an ecosystem perspective.

Methodology

Using Latent Dirichlet Allocation (LDA) topic modeling, we analyzed 73 studies to uncover seven core research themes and their interconnections.

Findings

The study highlights:

• Decentralization as the foundational principle of Web3.0.
• Blockchain, smart contracts, and DAOs as critical infrastructural components.
• Emerging use cases like the metaverse, NFTs, and DeFi.
• Gaps in governance, user experience, and regulatory frameworks.

Originality

This is the first systematic review integrating Web3.0’s technological, organizational, and socio-economic dimensions into an ecosystem framework.

Keywords

• Web3.0
• Blockchain
• Decentralized Networks
• Smart Contracts
• Metaverse
• NFTs
• Ecosystem

1. Introduction

Web3.0 represents a paradigm shift toward a decentralized internet, leveraging blockchain to empower user ownership and trustless interactions. Key innovations include:

• Token-based economies (e.g., cryptocurrencies, NFTs).
• Autonomous governance (e.g., DAOs).
• Decentralized applications (DApps) disrupting traditional models.

Challenges: Scalability, interoperability, and regulatory uncertainty.

2. Evolution of the Internet

2.1 Web1.0 (1990–2004)

• Static HTML sites with minimal user interaction.

2.2 Web2.0 (2004–Present)

• User-generated content (e.g., social media).
• Centralized platforms dominating data ownership.

2.3 Web3.0 (2021–Present)

• Read-Write-Own: Users control data via blockchain.

• Core Principles:

  • Decentralization
  • Permissionless access
  • Native crypto payments

3. Web3.0 Core Components

3.1 Blockchain

• Public ledgers (e.g., Ethereum) enabling secure, transparent transactions.

3.2 Cryptographic Assets

• Tokens for governance, payments, and staking.

3.3 Smart Contracts & DApps

• Self-executing contracts powering DeFi, gaming, and more.

3.4 Identity Systems

• Decentralized IDs replace traditional logins.

4. Research Themes from LDA Analysis
