Evolution from Centralization to Decentralization

Web2 is defined by its centralized architecture. Social media, payments, and data storage rely heavily on large platforms. While this offers convenience, it comes at the cost of user sovereignty, as the control over data and value was held by these platforms. Simply put, users generate value but do not own it.

Web3 aims to fundamentally change this paradigm. Through blockchain, smart contracts, and decentralized networks, users gain ownership of their data and assets. However, the gap between vision and execution is large—and the determining factor is “infrastructure”. High gas fees, low throughput, and complex development environments limit blockchain adoption on a large scale. This is the context in which infrastructures like {Gate Layer} emerge—focusing on efficiency and low cost to make decentralized applications usable at scale, dedicated to reconstruct the underlying architecture of Web3, making decentralization not only feasible but also efficient and usable.

Key Insights

In the evolution of infrastructure from Web2 to Web3, several key insights are worth our attention:

• Balance between centralization and efficiency: Web2’s centralized model is efficient, but users and developers have limited control over data and value; Web3 emphasizes decentralization, returning true value to users.
• Infrastructure determines ecosystem scalability: The underlying performance of blockchains directly affects application experience, transaction costs, and ecosystem growth rate.
• Efficiency and low cost are key to popularization: If transactions at the foundational layer are expensive and slow, small transactions and innovative applications will be hindered, and user stickiness and ecosystem vitality will be difficult to maintain.
• Rise of modular thinking: {Gate Layer} redefines underlying efficiency through modular architecture and high-performance design, providing new ideas for Web3 scalability.

Core Concepts Overview

To understand the practical path to efficiency and low cost, we need to grasp several core concepts:

• Monolithic chain vs. Multi-layer architecture
  Monolithic chains handle execution, consensus, and data within a single layer—simple, but limited in scalability. Multi-layer (Layered / Modular) architectures split responsibilities across multiple layers, improving performance and flexibility.

• Settlement layer, Execution layer, Data Availability (DA) layer
  Different layers perform different functions: the settlement layer ensures final consistency, the execution layer processes transaction logic, and the DA layer is responsible for data storage and availability. By separating functions, the complexity and operating costs of each layer can be significantly reduced.

• Why cost is crucial
  High gas fees not only increase the barrier to entry for users but also suppress the development of small transactions and innovative applications. Lowering network costs directly accelerates ecosystem growth.

The real Web3 revolution is not in the application interface, but in the underlying architecture. Understanding the logic of infrastructure revolution is the prerequisite for designing efficient, low-cost ecosystems. This lesson lays a solid foundation for subsequent in-depth discussions on modular, layered architecture, and high-performance networks.
