Describe Web 3.0. Blockchain-Based Internet Era



No matter what website you visit, the forum you join, or the social media platform you use, Web 3.0 is everywhere. People who do not share the broad enthusiasm for Web 3 refer to it as a “new buzzword” with a hint of contempt. They are unquestionably the minority, though. Everyone talks enthusiastically about it because they can see what is ahead.

Blockchain, cryptocurrencies, non-fungible tokens (NFT), and a host of other terms that, if you are not in the know, will make your head spin, come after Web 3.0. Of course, you also need to be knowledgeable on the subject! We are unsure of Web 3.0’s exact lifespan or whether Web 4.0 will eventually take its place. However, your firm won’t last very long if you don’t understand the fundamentals of technology.

Web3: What is it? Explained: The Decentralized Internet of the Future

The World Wide Web once had a huge impact on the “market” for knowledge available online. Now, thanks to the network, anyone with Internet access can access information from anywhere in the world. The fundamentals of communication have dramatically changed as a result of Web 2.0. Web 3.0 also emphasizes values and meanings more. Web 3 is a backend revolution, while Web 2 is an interface revolution.

In 2014, the phrase “Web 3.0” itself was coined. Gavin Wood, a co-founder of Ethereum, developed it. Simply, Web 3.0 replaces Web 2.0’s centralized storage with a decentralized method of online communication. The level of protection and safety of personal data is thereby greatly raised. And the blockchain system makes it all possible.

Describe Blockchain

Blockchain is a database that differs from other decentralized networks with a similar structure. There isn’t a single owner who has the legal right to utilize the data stored there, whatever he wants. Instead, the blockchain database is managed by all participants collectively and is open to all users. At the same time, it is now far more difficult to take this surface data.

Every action you do, including online buying and social media use, is supposed to be handled by the same safety procedures, increasing both your privacy and openness.

The blockchain system protects data using the cryptography concept; data is kept in blocks that line up in a chain to form a single whole. Thus, the name. Each block has its own timestamp, data, and hash pointing to the content in order to distinguish them somehow.

Those with enough tokens or cryptocurrency can manage these shares. You are eligible to vote on the network if you possess a sufficient number of these tokens. Holders of governance tokens can use their funds to vote on issues like the direction of the decentralized lending protocol.

What does Web3 mean in crypto?

You’ll note that cryptocurrencies are frequently discussed when web3 is brought up. This is because a lot of these systems heavily rely on cryptocurrencies. Additionally, it offers monetary compensation (tokens) to anyone who wishes to design, oversee, support, or enhance one of the projects.

Many services may be provided using these protocols:

  • Calculations
  • Storage
  • Bandwidth
  • Identification
  • Hosting

Similar to today’s cloud service providers, service users often pay to use the protocol.

The market for decentralized finance (Defi), which was made possible by cryptocurrencies, is thriving and steadily expanding. Applications for Web 3 are frequently built using the Ethereum platform, which, like bitcoin, compensates users for the upkeep of the network. The market value of this cryptocurrency, called Ether, is $511 billion.

The apps themselves may also have associated tokens that serve as voting shares that control how the apps are developed, including how much they cost.

A Web3 app: what is it?

Applications developed for Web 3 run either on blockchains or in decentralized networks made up of several peer nodes (servers), or they run in a combination of both, creating a crypto-economic protocol. These applications are distributed.

Distributed apps (or dApps), created on the Ethereum blockchain, are at the core of Web3, and they reward users for maintaining it online. Dapps serve the same purpose for Web 3.0 as the App Store does for the current Apple environment.

On the DappRadar tracker, there are more than 8,700 decentralized applications that are currently operational. Games and various cryptocurrency trading sites are among them. Sometimes there is a blurring of the lines between the two because many games include exchanging non-fungible tokens, or NFTs, virtual characters, or collectables that can fetch exorbitant prices in exchange for winnings.

The majority of decentralized applications are now used for trading NFTs or cryptocurrency exchanges. Only a small portion of dApps are games that may be played for cryptocurrency rewards.

NFT and Web3

In relation to gaming… Gamers in the Web 2.0 era can only dislike how many problems are in the upcoming instalment of their favourite game. With Web 3.0, players can really create the game themselves by using their tokens to vote on the necessary improvements. In the gaming sector, NFT is likewise a rising star. Gamers are shopping for virtual reality-related goods.

Additionally, everything may now be tokenized, be it a piece of music, a painting in a museum, a meme, or even your cat. Therefore, one of the infamous NFT Rare Bored Ape Yacht Club was sold for $3.4 million in 2021!

Anyone can now financially contribute to the development of a game, unlike in the past when venture capitalists used their own funds and dictated to the designers the conditions that would allow profit to be made in the shortest amount of time. The business announces the release of x tokens, distributes 10% to early investors, offers 10% for sale, and reserves the remaining tokens for future contributions and project funding.

This idea will probably be perceived by some as being too similar to a financial pyramid. However, buyers have total transparency about what is happening because all blockchain data is completely public and accessible. Network marketing firms that do not abstain from fraud also keep all of this a secret.

Opportunities, Problems, and Challenges with Web 3.0

A decentralized internet is appealing as a concept. As soon as we think of the “oppression of the capitalists” that controls large portions of our everyday life, we immediately envision freedom. But not everything is as bright as it seems.

Who is now making the largest investments in Web 3.0? Large IT firms, hedge funds with multimillion-dollar funding, and venture capitalists. As a result, the distribution of modern blockchain networks is uneven. In other words, only a small number of powerful investors own the encryption keys for enormous sums of money. The fact that information is now kept in multiple locations makes it much more challenging to manage. However, if you simultaneously choose numerous figureheads who will take part in the decentralization plan, the entire idealistic notion is for nought.

Some analysts go a step further and contend that Web 3.0 is really just the same centralized organization under a different moniker. Elon Musk, who needs no introduction, claims that web3 social media app development is more of a “marketing buzzword” than a true technology.

It’s important to note that certain cybersecurity professionals stress that while it may be harder to hack data in the blockchain format, it is also nearly impossible to avoid such an attack. In the end, the problem is not whether individuals can access it quickly but rather if they are aware of how to manage their data safely. The rampant theft of cryptocurrency is one illustration of such an issue.

Even though many projects enable online chat rooms, they rarely even provide contact information. Money could be gone forever if you transfer it to the wrong account due to a typing error. As if you had called the bank’s customer service, you would not be able to resolve the issue. After all, in Web 3.0, God assists those who help themselves, whereas, in Web 2.0, the bank is responsible for your financial stability. Freedom comes with a burden that not everyone can handle.

Many Web3 needs, like distributed architecture and decentralization, are thought to be better implemented without blockchains, according to sceptics, since nothing is fundamentally altered by creating a decentralized system built on a centralized one.

As a result,

Does Web 3.0 technology, which has not yet cemented its place in modern society, therefore no longer justify itself? As with every novel idea, there will always be fraudsters looking to profit, as well as devotees who will produce truly fantastic things. So, is Web 3.0 a blessing or just Web 2.0 with a few updates? The next ten years will demonstrate this. Whatever the situation, much depends on how the major actor’s act.
