Introduction To Blockchain And Web3

Web 2.0, the latest iteration of the internet, is generally characterized as interactive and socially oriented, marking a significant shift from the “read-only” Web 1.0. Web 3.0, also known as Web3 in the virtual asset industry, is the next generation of the internet, and its implementation is now underway. The promise of Web3 lies in its potential to provide users with more control over their personal information and digital possessions and facilitate frictionless online transactions. Products in the blockchain and cryptocurrency ecosystems are already functional and will be used in Web3. Cryptocurrency wallets allow users to conduct P2P payments and store digital assets. Numerous blockchain-based initiatives are open and decentralized for anybody to join.

What Is Blockchain Technology?

When it comes to decentralization, blockchain networks are the next big thing. With blockchain, an app or a website may “exist” on several servers, each separately owned and maintained. This ensures that no one entity has a monopoly over the network. Thanks to blockchain technology, the new Web3 architecture is feasible.

A blockchain is a network of servers or computers that are physically dispersed but work together to keep a single, immutable copy of a ledger of transactions or other data. People often refer to this shared record as a “ledger” since it serves a similar purpose to a standard accounting ledger. Although the information recorded on these distributed ledgers is not limited to bitcoin transactions, that is where most of the data is often found.

Each piece of information is organized into a “block” and linked to the next linearly. Processing adds additional data blocks to the chain’s final block. If one piece of information were to “break,” it would have a devastating effect on the rest of the chain.

What Is Web3?

Web3 is a new internet that aims to fix problems with the present internet, such as the abuse of users’ personal information and the centralization of power within several social media platforms. Digital assets may become an integral element of Web3. Blockchains’ ability to operate without requiring authorization from any third party is a significant step toward decentralizing communication power and away from centralizing it in the hands of governments.

While digital assets are mostly used as tokens in digital economic systems, they may also be used for making native digital payments on Web3. Moreover, by using DAOs, autonomous organizations powered by blockchain technology, Web3 might become more community-oriented (DAOs).

Blockchain and digital currencies aren’t just a sidenote of the Web3 trend. They play a crucial role in the distributed nature of Web3, making it a viable technology. You couldn’t have the system without them.

Blockchains cannot encourage user engagement in the network without cryptocurrency. Users would need crypto wallets to keep their crypto. Furthermore, Web3 is only possible with the infrastructure provided by blockchain networks.

All of these technologies work together to make possible Web3, the next generation of the internet, that is not governed by a central authority. With its integrated cryptocurrency wallet and direct support for the Basic Attention Token (BAT), the Brave browser provides a quick and safe method to access Web3.

How Do Blockchain And Crypto Fit Into Web3?


The concentration of data and power in the hands of just a few key businesses is a significant issue in the Web2 ecosystem. By allowing for more equitable sharing of data and resources, blockchain and cryptocurrencies may help decentralize Web3. In addition, Web3 may use blockchain-powered public distributed ledgers to facilitate more openness and democratization.


Open-source blockchain initiatives use public ledgers to replace proprietary systems used by conventional businesses. Since blockchain apps are permissionless, they may be accessed and used by anybody, anywhere in the world.


Using blockchain and cryptocurrency removes the need to rely on a central authority, such as banks or an individual middleman. As a result, users of Web3 may do business without placing their faith in a third party.

🔹Payment rails

Cryptocurrencies have the potential to become Web3’s native digital payment system. Because they are genuinely borderless and don’t need intermediaries, digital assets can streamline the cumbersome and costly Web2 payment infrastructure.


Self-custodial crypto wallets enable users to hold cash independently of any third parties and are one example of the solutions now available in the crypto space. Wallets may be linked to decentralized applications so that users can spend or display their digital assets in several ways. In addition, a public ledger makes it possible for anybody to confirm the ownership of these assets.

🔹Censorship resistance

Blockchains are created to avoid censorship by ensuring that a single entity cannot alter the ledger of transactions. Therefore, it is very difficult to delete a block from the blockchain after it has been added. Because of this function, it may be possible to protect all forms of expression against governmental and corporate restrictions.

Is blockchain essential for Web3?

Web3 may use technology unrelated to blockchain or cryptocurrencies. Virtual reality (VR), Augmented reality (AR), the metaverse, and the internet of things (IoT) are examples of technologies that might play a pivotal role in the next generation of the internet. While blockchain may play a larger role in Web3’s underlying architecture, the technologies above and solutions have the potential to make the web more interactive and grounded in the real world.

The Internet of Things (IoT) has the potential to link disparate devices together through a network. At the same time, augmented reality (AR) may insert computer-generated visual components into the actual world. Virtual reality (VR) can create artificial worlds with goods depicted as digital assets. Scaling and integrating these technologies may make a single metaverse a reality in Web3.

Cryptocurrency has the potential to provide several advantages, including the development of digital payment infrastructure. Utility tokens may enable a wide variety of Web3 applications. Non-fungible tokens (NFTs) also validate digital identity and ownership without compromising users’ privacy.


As you can see, blockchain is an innovative method of reaching agreement amongst users on a network without needing a central authority. However, Web3 is a distributed network where no one entity (such as a bank) is required to provide services online. So in what ways do they cooperate? In a nutshell, blockchain technology provides the necessary decentralization for Web3.
