Blockchain vs. Web3: What's the Difference and Which One Should You Work In?

Date: 11 Apr 2023

Introduction

Blockchain and Web3 are two terms that have been creating a buzz in the tech industry. Both technologies are promising and have the potential to revolutionize the way we live, work and interact with each other. However, there is often confusion about the difference between Blockchain and Web3, and which one to work in. In this article, we will dive deep into the two technologies, explore their differences, advantages and disadvantages, and help you decide which one to work in.

What is Blockchain?

Blockchain is a distributed ledger technology that allows secure, transparent and tamper-proof recording of transactions. It was invented in 2008 by an unknown person or group of people using the pseudonym Satoshi Nakamoto, for the cryptocurrency Bitcoin. Blockchain operates on a decentralized network, where transactions are verified and recorded by a network of nodes, instead of a central authority.

How does Blockchain work?

Blockchain works by creating a block of transactions, which are verified by nodes on the network. Once the block is verified, it is added to the chain of blocks, forming a permanent record of the transaction. This record cannot be altered or deleted, as every block in the chain is linked to the previous one and contains a unique cryptographic hash.

Advantages of Blockchain

Decentralized network - eliminates the need for a central authority
Transparency - all transactions are recorded and can be verified by anyone on the network
Security - transactions are encrypted and tamper-proof, making it difficult to hack or manipulate
Efficiency - eliminates intermediaries, reducing costs and time for transactions

Disadvantages of Blockchain

Slow transaction processing speed
High energy consumption - due to the complex computations required for verification
Complexity - difficult to understand and implement for non-technical users
Limited scalability - current blockchain networks can handle only a limited number of transactions per second

What is Web3?

Web3 is the next generation of the internet, where users have more control over their data and digital identities. It is a decentralized web, where users interact with each other and applications without the need for intermediaries. Web3 is built on top of blockchain technology, but it goes beyond just transactions, enabling a more decentralized and democratic internet.

How does Web3 work?

Web3 works by enabling users to have control over their data and digital identities through the use of decentralized applications (dApps). These dApps run on a decentralized network, where users can interact with each other and the applications directly, without the need for intermediaries. Web3 also uses blockchain technology to provide transparency, security, and immutability.

Advantages of Web3

Decentralized network - eliminates the need for intermediaries and enables more control for users over their data
Democratization - enables a more democratic and fair internet, where power is distributed among users and not just a few tech giants
Transparency - blockchain technology provides transparency and security for transactions and data
Innovation - Web3 enables new forms of decentralized applications and business models, creating opportunities for entrepreneurs and developers

Disadvantages of Web3

Complexity - Web3 is still in its early stages and requires technical knowledge and skills to use and develop dApps
Speed and scalability - current Web3 networks can be slow and have limited scalability
Regulatory challenges - as Web3 enables more decentralized and anonymous interactions, it can pose regulatory challenges for governments and businesses

Blockchain vs. Web3: What's the Difference?

Now that we have explored the basics of blockchain and Web3, let's dive into the key differences between the two technologies:

Centralization vs Decentralization

The biggest difference between blockchain and Web3 is the level of centralization. Blockchain operates on a decentralized network, where transactions are verified and recorded by a network of nodes, instead of a central authority. Web3, on the other hand, aims to create a more decentralized internet, where users have more control over their data and digital identities and interact with each other and applications without intermediaries.

Transactions vs Interactions

Another key difference between blockchain and Web3 is the focus on transactions vs interactions. Blockchain technology was primarily designed for secure and transparent recording of transactions, while Web3 aims to enable more decentralized and democratic interactions between users and applications.

Cryptocurrency vs dApps

Blockchain technology is most commonly associated with cryptocurrencies like Bitcoin and Ethereum, while Web3 enables the development and use of decentralized applications (dApps). While both technologies use blockchain technology, their focus and applications are different.

Which One Should You Work In?

Now that we have explored the differences between blockchain and Web3, the question arises - which one should you work in? The answer depends on your skills, interests and goals.

If you are interested in developing blockchain-based applications or working in the cryptocurrency industry, then blockchain would be a good choice for you. Blockchain technology is still evolving and has enormous potential for disruption in various industries, such as finance, healthcare and supply chain management.

On the other hand, if you are interested in creating decentralized applications and contributing to the development of a more democratic and fair internet, then Web3 would be a good choice for you. Web3 is still in its early stages, but it has the potential to revolutionize the way we interact with each other and the internet.
