Web3 is a concept built on blockchain technology that seeks to shape the internet's future. It describes a new version of the internet under shared user control.
The internet continually grows and evolves. That change affects not just websites and platforms but the underlying code itself. Web3 emerged as a response, emphasizing a structure controlled by its users.
Web3 is based on blockchain: a digitally distributed, decentralized ledger. As transactions and new data are recorded, permanent blocks are created, added to the chain and reflected across the nodes. This collective structure means the system does not depend on a single point of control.
Web3's central principle is to give users greater control online. Rather than relying on a traditional centralized model, people can control their own data and access it more securely. Distributed ledgers support secure, transparent information sharing.
The Rise and Importance of Web3
Web3 has gained significance rapidly in recent years. Equity investment, online searches, patent applications and scientific publications have shown considerable momentum around its components. Financial services have taken a leading role, with daily transaction volumes on decentralized platforms exceeding billions of dollars.
How Web1 and Web2 Led Here
Understanding Web3 begins with Web1 and Web2. Looking at the internet's evolution helps explain today's digital landscape.
Web1: The Internet's Early Steps
Web1 was the internet's first iteration, used from the late 1990s to the early 2000s. Websites generally relied on open protocols and offered ways for anyone to exchange information. People mainly used the internet to read pages and chat with friends or strangers.
Over time, individuals and companies increasingly used Web1 for e-commerce, academic work and scientific research. Its limitations became apparent, however, and users began seeking more control and interaction.
Web2: Centralized Control and Interaction
Web2 evolved from Web1 and represents the prevailing internet model. Transactions, content and data became centralized within technology companies. Large platforms provided interactive services, while the rise of social media increased interaction between individuals.
This centralized model also created concerns about data security, privacy and user control. People began wanting more authority over their own information.
Technologies Behind Web3
Web3 includes several kinds of technology. The most important include:
Blockchain
A blockchain is a digitally distributed, decentralized ledger for recording transactions securely. When data is added to the network, a new block is created and permanently added to the chain. Nodes update to reflect the changes. The structure means the system is not dependent on a single point of control or failure.
Smart Contracts
Smart contracts are software programs that execute automatically when specified conditions between buyer and seller are met. Written as code on an immutable blockchain, they help prevent disputes and make transactions more secure.
Digital Assets and Tokens
Digital assets and tokens are items of value that exist in digital form. They can include cryptocurrencies, stablecoins, central bank digital currencies (CBDCs) and non-fungible tokens (NFTs). Tokenized versions of real-world assets, such as artworks or concert tickets, are also included.
These three elements form the foundations of Web3 and play an important role in shaping the internet's future. Web3 aims to transform online experiences by strengthening trust between users and providing a decentralized, transparent structure.
Key Differences Between Web3 and Web2
Web3 and Web2 differ significantly in how they approach control over transactions and the basis of trust. Their main distinctions are:
Centralized Control Versus User Control
Web2: Transactions, content and data are centralized within technology companies. Users typically receive services through platforms owned by large businesses, which control their information.
Web3: Users gain control over their own information. Distributed ledgers and blockchain replace centralized control, allowing people to manage data more securely.
How Trust Is Established
Web2: Trust depends on information shared between two parties, usually through a central intermediary. During an e-commerce transaction, for example, buyer and seller exchange information through the platform and base their trust on it.
Web3: Trust is established through technology. Users rely on specified conditions being met and data being verified before a transaction occurs. Blockchain and smart contracts provide the means to establish that trust.
