The Evolution: From Web1 to Web3

Web1: The Static Web (1990s – early 2000s)

The earliest iteration of the internet, often referred to as Web1, was characterized by static, read-only web pages. This era saw the breakthrough contribution of Tim Berners-Lee in 1989, who introduced the World Wide Web as a new layer to the internet. His system, utilizing hyperlinks to connect documents, a shared language (HTML) to structure them, and a protocol (HTTP) to transfer them, provided a crucial way to navigate the nascent internet.

Web2: The Social and Interactive Web (mid-2000s – today)

The mid-2000s ushered in Web2, a phase defined by dynamic, interactive platforms and user-generated content. This era was propelled by key innovations such as widespread mobile internet access and the proliferation of social networks, alongside the near-ubiquity of powerful mobile devices like iPhones and Android-powered smartphones.

However, this period of enhanced connectivity also led to significant centralization. A handful of major tech companies came to control vast amounts of user information, raising considerable concerns about data ownership and privacy. The convenience offered by Web2 platforms often came at the cost of users relinquishing control over their personal data, creating a "user as product" model.

Web3: The Decentralized Web (Emerging Today)

Web3 represents the next evolutionary phase of the internet, driven by blockchain technology to prioritize decentralization, security, and user control. This progression from Web1's "read-only" to Web2's "read/write" and now to Web3's "read/write/own" paradigm signifies a continuous drive towards greater user empowerment and control over digital experiences.

Key Features Of Web3

Decentralization

Instead of relying on centralized servers, Web3 utilizes a distributed network of computers. This approach enhances resilience, reduces single points of failure, and mitigates the risk of censorship. Information is found based on its content, allowing it to be stored in multiple locations simultaneously, dismantling the vast data monopolies held by major internet companies.

Blockchain

This foundational technology ensures security, transparency, and immutability of data. Blockchain serves as a distributed ledger. It records transactions and interactions in a tamper-resistant manner.

Each computer in the blockchain network maintains its own copy of the data. This makes it exceedingly difficult to corrupt or manipulate records.

Smart Contracts

These contracts are critical components of blockchain technology. They're stored on the blockchain layer and leverage its security and transparency.

Smart contracts enable trustless interactions between parties. By eliminating intermediaries, they form the backbone of many Web3 applications. This includes everything from decentralized finance (DeFi) to supply chain management.

DApps (Decentralized Applications)

These applications run on a blockchain network. They primarily interact with smart contracts to execute their core functionality.

Unlike traditional apps, DApps operate without a central authority. They distribute their backend code across the blockchain network. This offers users greater control over their data and interactions.
