Think about how much the internet has changed since it kicked off in 1983. What started as a primary way to share information has become a super complex platform that powers automated applications.
Sounds interesting, right? So, let’s take a quick trip through the history of Web3 to see how it evolved and what makes each version unique.
History of Web3
The internet has evolved from a basic, unchanging space into a more interactive and decentralized system. Understanding this change is important to see why Web3 matters and how it could shape the future of the online world.
Web1
To better understand how the internet has changed, imagine it as a library. In the early days, Web1 was like a quiet library with just a handful of big publishers filling the shelves with books. You could read those books, but that was it — no adding, no changing. It was all one-way communication: from them to you.
Web2
Then, Web2 came along and shook things up. Suddenly, that library became a lively social hub where anyone could contribute their books — think websites, blogs, you name it. It became a bustling space where readers and writers were both actively involved. But here’s the catch: A few big players, like Google or Facebook, still controlled the library. They decided which books stayed, the rules and how everything was organized.
Web3
Now, Web3 is taking things to a whole new level. Picture a decentralized library made up of independent book clubs. No one’s in charge, and everyone can join in and share their knowledge. It’s more like a public square where anyone can join the conversation.
Thanks to blockchain, books are safely stored on a distributed network, so no one can mess with them. Plus, you own what you contribute — and might even be rewarded for it. This makes the whole process of organizing information way more democratic and fair.
Web3 is all about putting control back in the hands of users rather than a central authority. It aims to make the internet more transparent, open and where everyone’s voice matters.
Understanding Web3 is essential because it’s where the internet is headed. Understanding it will help you stay ahead of the curve and be ready for all the exciting changes and opportunities.
Web3 explained
So, the next big thing in the internet world is Web3, or the decentralized web. It’s a game-changer because it uses blockchain technology to shift control from big companies back to the users — people like you.
With Web3, there’s no need for those central entities because everything runs on decentralized apps that work on peer-to-peer (P2P) networks. This means more openness and better data privacy, and it’s way harder for anyone to censor information.
Let’s break down the characteristics of Web3:
- Decentralization: This is all about spreading power and decision-making across a network rather than letting one person or big company call the shots. It gives you more control over your online experience and reduces the influence of those big players.
- Permissionless and trustless communication: On Web3, you don’t need a bank or intermediary to handle transactions. You can just do it yourself. Anyone can join the system without asking for permission, which means it’s open and inclusive.
- Improved security and privacy: Web3 increases privacy by giving you more control over who can access your data and how it’s used. Plus, it uses cryptographic techniques that make it hard for bad actors to mess with your information.
- Interoperability: One of the coolest things about Web3 is how it seamlessly integrates different platforms and systems. You can easily transfer data and assets between various apps, making your online experience smoother and more convenient.
- Ownership and control of data: In Web3, you’re the boss of your data. You get to decide how it’s used and shared. Want to monetize your data? Go for it. Prefer to keep it private? That’s your call.
So, Web3 gives you more control, security and freedom online. It’s something to watch as it continues to evolve!
Did you know? In 2021, Twitter (now X) took a big step into Web3 by allowing users to link their cryptocurrency wallets to their Twitter accounts. This allowed them to use verified non-fungible tokens (NFTs) as their profile pictures, making Web3 technology more accessible and popular.
Core components of Web3
Here are the core components that make Web3 possible:
Blockchain
First, we’ve got blockchains — the backbone of Web3. Imagine a digital ledger that records transactions and data across a network of computers or nodes. The cool thing about blockchain is that it stores information in a way that makes it nearly impossible to change anything without altering all the connected data blocks. This keeps everything super secure.
Each block in the blockchain has a list of transactions, and these blockchains can be public, private or somewhere in between, called consortium blockchains. Public blockchains are open to everyone, whereas private ones are restricted to specific users.
The consortium kind of blends the best of both worlds. By ditching centralized authorities, blockchain gives more control to the network members, making it a key player in the Web3 world.
Cryptocurrencies
Next, let’s talk about cryptocurrencies. These digital currencies are crucial to the decentralized internet, giving you control over your finances without a bank or government. They’re like digital cash, using cryptography to keep transactions secure.
Cryptocurrencies are the economic backbone of Web3, powering decentralized apps and networks. Bitcoin (BTC) is the oldest and still the top player, holding around 56% of the crypto market as of Aug. 15, 2024. On the same date, Ether (ETH) was placed as the second-largest with about 15% market share.
These currencies let you send money across borders, support blockchain projects and more, all without the need for intermediaries. It’s a new way of handling money central to how Web3 operates.
Smart contracts
Now, imagine contracts that don’t need a lawyer or an intermediary to enforce them — that’s what smart contracts are. They’re automated contracts that run on blockchain networks and execute actions automatically when certain conditions are met.
For instance, say you’ve got an insurance claim; a smart contract could automatically release your payment once your claim is verified, without human interference. Smart contracts are used in finance, supply chains and more, streamlining processes and reducing the chance of disputes. They’re a big part of how Web3 keeps everything decentralized and efficient.
Decentralized applications (DApps)
Finally, let’s talk about decentralized applications (DApps). Unlike regular apps on a centralized server, DApps operate on a blockchain. They’re usually open-source, meaning anyone can check or contribute to the code. This open approach encourages innovation and collaboration among developers.
You’ll find DApps in finance, gaming, social media and supply chains offering new and innovative ways to interact and trade. DApps are about giving users more control, privacy and transparency, sticking closely to Web3’s principles of creating a more decentralized and fair internet. Many DApps also use tokens to encourage user participation and reward contributions to the network.
So, these components — blockchain, cryptocurrencies, smart contracts and DApps — make Web3 tick. Together, they’re building a new kind of internet that’s secure, fair and user-focused.
Key features and applications of Web3
Let’s dive into how Web3 is changing the game with some cool features and applications:
Decentralized finance (DeFi)
Imagine handling all your financial transactions without needing a bank or any intermediary. That’s what decentralized finance is all about. It uses blockchain technology to let you lend, borrow, trade and invest directly with others. No matter where you are or your financial situation, DeFi gives you easy access to financial services.
And because there are no intermediaries, transactions are usually faster and cheaper. Plus, you’re in full control of your money. With just a crypto wallet, you can dive into advanced financial activities such as insurance or trading derivatives, all in a decentralized way.
Did you know? In 2023, a whopping $100 billion+ got poured into DeFi lending, highlighting the increasing popularity of decentralized lending options.
Non-fungible tokens (NFTs)
You’ve probably heard of non-fungible tokens, or NFTs, by now. Unlike regular cryptocurrencies, which are all the same and can be swapped easily, NFTs are unique digital assets on a blockchain. This uniqueness makes them perfect for owning virtual real estate, music, movies, collectibles and digital art.
For example, artists can sell their work directly to fans using NFTs and get paid fairly. NFTs also allow for cool experiences like virtual art exhibitions. Each NFT has a clear, verifiable ownership history, making it a secure way to prove ownership of digital goods.
Decentralized autonomous organizations (DAOs)
Decentralized autonomous organizations (DAOs) are like organizations run by their members using blockchain technology, with no need for a central authority. Everyone in a DAO can participate in decision-making through smart contracts, and because everything is on the blockchain, it’s all transparent and publicly visible.
DAOs make it easy for people to collaborate and make decisions that benefit the group. They can be used for various things, like managing projects, building communities and more.
Decentralized social media
Imagine social media where you’re in control — not some big company. That’s the idea behind decentralized social media. Instead of being run by a single entity like Facebook or X, it’s spread across a network of computers. This means no one controls your data or decides what you see in your feed.
On decentralized social media, you have more control over your posts and privacy. You can even communicate directly with others without needing an intermediary. While it’s still early, decentralized social media could change how we connect and communicate online.
Decentralized identity management
Managing your data online can be tricky, but decentralized identity management is here to help. Instead of storing your data on centralized servers like in traditional systems, it’s distributed across a network of computers. This gives you more control over who can access and use your information.
With a decentralized identity, you decide what information you share with different websites and services, helping to keep your privacy safe in this digital world.
So, Web3 is bringing some amazing innovations — from financial freedom with DeFi and owning digital art with NFTs to transparent organizations with DAOs and more private and secure online interactions. It’s an exciting time to see how these changes will shape our digital future!
Web1 vs. Web2 vs. Web3
Here is how Web1, Web2, and Web3 compare with one another:
Challenges and limitations of Web3
While Web3 offers exciting possibilities, there are also many obstacles to it:
Scalability
Think of a busy freeway. In Web3, getting more users is like adding more automobiles to the already congested freeway. After a threshold, Web3, like a freeway, will struggle to accommodate heavy traffic. In other words, as users grow in Web3, transactions may grow costly and slow down.
Web3 developers have consistently worked to overcome this problem. The Polkadot network, for instance, can process more than 1,000 transactions per second, which is significantly more than seven for Bitcoin and 30 for Ethereum. Yet it is much lower than the processing speed of VisaNet, a global processing network that can handle more than 65,000 transactions a second.
Pace of adoption
You could compare Web3 with a brand-new eatery with delicious food but with few tables and employees. Though the eatery isn’t well-known, it holds a lot of promise. Lack of awareness has slowed down its adoption.
As a restaurant requires more patrons to expand, Web3, too, requires more users to increase its acceptance. Many still feel apprehensive about Web3 because of the lack of regulatory clarity and complex sign-up processes. Things are improving, and this should accelerate the acceptance of Web3.
Complex security mechanism
Web3 security can be difficult to understand for beginners. If you forget your private key or recovery password when using a decentralized exchange or any other app, you risk losing access to your assets. In self-custody systems, there is no provision for regenerating passwords and regaining access to funds.
Individuals who aren’t used to such a system might find it challenging. You need to be more informed and accountable for your own security. As user-friendly security features develop in Web3, it will become even simpler for you.
Regulatory concerns
Regulators worldwide are concerned about possible illegal activities in Web3, such as money laundering and fraud. Conventionally, regulations have been drafted because of proprietorships and large businesses with centralized authority. After the emergence of Web3, regulators have been working to catch up.
In general, the objective of regulators has been to safeguard users without blocking innovation. They’ve been working to bring clarity to regulation to foster confidence in the users of Web3.
How Web3 may further evolve
With exciting possibilities in the future, Web3 is still evolving. You can expect the following developments:
- Interoperability: As blockchain networks grow increasingly integrated, data and assets may easily move between platforms.
- AI integration: Processes will be automated; the user experience will get smoother; and new possibilities for DApps will come to life.
- Integration with real-world assets and services: It’s likely to become more intertwined with real-world assets and services. It could revolutionize supply chains, identity verification and even voting systems.
- New governance models: You could see DAOs evolve into even more inclusive and complex governance models.
The future of Web3 is looking incredibly bright. It can potentially revolutionize not just the internet but society as a whole. As technology advances, we can expect to see innovative applications that transform how we interact online. The possibilities are endless, and seeing how Web3 shapes our digital lives in the coming years will be exciting.
