What is Web3 and why are all the crypto people suddenly talking about it? ›

Web3 (also known as Web 3.0) is an idea for a new iteration of the World Wide Web which incorporates concepts such as decentralization, blockchain technologies, and token-based economics.

While blockchain solutions can ensure the integrity of digital data by providing a tamper-proof record of transactions, they cannot verify the authenticity of physical items.

Blockchain can also be used to reduce fraud and other trust-related issues in digital ad buying. Blockchain has a wide range of applications in healthcare, including improving payment processing, electronic medical records, provider directories, and data security and exchange.

Blockchains makes it easy to ascribe ownership to data, thereby facilitating the transfer of rights and royalties based on fair use. This would enable a universal data marketplace that has never been seen before.

Web3 is a term used to describe the next iteration of the internet, one that is built on blockchain technology and is communally controlled by its users. 3D illustration of a human hand and a digital hand reaching through geometric portals and touching finger tips at the center of the frame.

Web3 Internet uses blockchain technology—the same technology that underpins Bitcoin and other cryptocurrencies—to make the decentralized Internet more secure and private. Web3 systems are technology protocols controlled by computer code to facilitate direct and secure communications among users, applications, and data.

Scalability

This makes the validation of transactions very slow and tedious. There is no scope to increase the size of the block on a blockchain. Networks like Polygon have features to upscale the transaction speed of Ethereum, which is quite well-known for its slow network speeds.

No financial system is 100% tamper-proof. Hence, blockchain is no exception. But blockchains are extremely difficult to hack or breach because of their specially-crafted design. There are however two ways to take over the security of a blockchain and its established security mechanism.

It has been argued that blockchain projects are secure, but attacks over the years have demonstrated that this is only partially true. Over $1.7 billion in cryptocurrency was stolen in 2023 ($3.8 billion in 2022), according to blockchain analysis firm Chainalysis.

What is blockchain in simple words? ›

Blockchain is a shared, immutable ledger that facilitates the process of recording transactions and tracking assets in a business network. asset can be tangible (a house, car, cash, land) or intangible (intellectual property, patents, copyrights, branding).

In the simplest terms, a blockchain is formed by stringing together different blocks. Each 'block' is a set of data or some kind of information – most commonly, transactions. Nobody 'owns' blockchain technology.

Blockchain reduces the probability of security breaches by limiting access to information encoded on an immutable ledger, making it easy to identify anyone trying to manipulate data.

Putting it all together. Blockchain ensures data storage and privacy to increase the data integrity, whereas the big data deals with data ensuring the data quantity, velocity, and variety to deliver better predictions. The combination of these technologies is unbeatable.

Scalability:

The ability to manage a large number of users at a single time is still a challenge for the blockchain industry. Blockchain technology involves several complex algorithms to process a single transaction.

With Web3, a decentralized internet can be established, giving consumers more authority over their data and online activities. Blockchain technology makes Peer-to-peer transactions possible, eliminating the need for intermediaries while improving security and anonymity.

Critics of web3 see it as a breeding ground for unregulated crime and get-rich-quick Ponzi schemes that can harm vulnerable consumers. Still, others fervently hope that if they just ignore it — or worse yet, ban it — web3 will just go away. The truth about web3 lies somewhere in between these viewpoints.

Key aspects of Web3 include blockchain, cryptocurrencies, smart contracts and decentralized apps (DApps). Web3 opens up new possibilities in areas like decentralized finance (DeFi), non-fungible tokens (NFTs), decentralized organizations (DAOs), social media and identity management.

Web 3.0 is the next-gen World Wide Web based on advanced technologies and protocols enabling machines to understand and interpret information, which makes the Web more smart and human-like.
