An Introduction to Web3 Basics

The Internet has never been neutral. The platforms you use, the data you give, and the content you create have been under someone else's control.

You scroll Instagram, but Meta owns your profile. You post on Twitter, but X decides if you get banned. You send money through PayPal, and they can freeze your account.

Web3 changed that. It introduced a shift in how the Internet works, changing who owns, controls, and earns from it.

Instead of big companies running the show, Web3 gives control back to the people who use the Internet. You keep your data and own your identity. You can even help run the platforms you use.

That’s why it matters. It’s not about trends. It’s about power.

‍

Quick Recap: Web1 and Web2

To understand Web3, you need to know what came before it.

Web1 (roughly 1990–2005)

This was the read-only Internet.

You could browse static websites, read articles, and maybe sign up for email newsletters. But you couldn’t post, comment, or upload. It was like a one-way digital newspaper controlled by developers.

Web2 (2005–today)

This is the social Internet, you know.

You can post, share, comment, like, upload videos, and build audiences. But here’s the trade-off: You don’t own any of it. Your data, your content, your reach they all live on platforms that can change the rules overnight.

Web2 gave you access. It also took control.

‍

So, What is Web3?

Web3 is the next version of the Internet built on blockchains, run by users, and designed for ownership.

• Instead of platforms owning your content, data, or identity, you do.
• Instead of needing permission to participate, you don’t.
• Instead of trusting companies, you trust code.

Let’s break that down:

• Web3 uses blockchain — a public system that records data so no one can change it behind the scenes.
• You log in with wallets, not passwords. Your identity is yours, portable across apps.
• You can own digital assets — NFTs, tokens, usernames, memberships, and game items. These are not just files; they’re absolute values you control.
• You can help govern platforms — with tokens that let you vote on decisions no more closed-door policy changes.

Web3 isn’t just about technology. It’s about removing gatekeepers. It’s not just “crypto”. It includes social networks, games, finance tools, DAOs, and more.

What Makes Web3 Different?

‍

In Web2, you are the product. In Web3, you become the owner. That’s the core shift not just decentralization or crypto wallets. It’s about flipping control from corporations to communities.

Why Are People Excited About Web3?

Web3 promises absolute control and new opportunities. You decide what happens with your data and identity: no more hidden rules or surprise bans.

Creators earn directly from their work without intermediaries taking significant cuts. Imagine musicians, artists, or writers getting paid fairly every time someone uses their content.

Communities govern themselves. Token holders, not distant CEOs, vote on platform changes. This creates systems built around users, not profits alone.

Web3 also opens up new business models, like decentralized finance (DeFi), in which people can borrow or earn interest without banks.

However, it’s still early. Not everything works perfectly. Some projects fail, scams exist, and the tech can be confusing.

However, the potential is clear: Web3 offers a more transparent, fair, and user-owned internet.

‍

How Does Web3 Work?

Web3 removes intermediaries. Instead of relying on companies to store data or approve transactions, it uses blockchains, decentralized networks of computers that agree on the truth.

At the center is the blockchain, a public ledger. Every transaction or record is stored there, visible to everyone, and hard to change.

You don’t use a username and password. You connect through a wallet like MetaMask or Coinbase Wallet, which stores your digital identity and assets.

Web3 apps (called dApps) run on smart contracts. These are programs stored on the blockchain that execute actions when conditions are met. Once deployed, no company can stop or alter them.

Many Web3 platforms use decentralized storage like IPFS (InterPlanetary File System) or Arweave instead of hosting on centralized servers. This makes data harder to censor or delete.

Tokens power Web3. You might earn tokens to contribute to a platform, vote with them on decisions, or use them to access services.

In short, Web3 replaces platforms with protocols. It replaces CEOs with code. These components work together to give users control, security, and transparency.

What Challenges Does Web3 Face?

Web3 is promising, but it’s far from perfect. Most people don’t understand how it works. Wallets, private keys, gas fees, it’s overwhelming. Onboarding is slow, and mistakes are irreversible.

The user experience is sometimes clunky, and signing transactions, switching networks, and debugging failed swaps may be challenging to understand.

Scams and rug pulls are common. In 2024, Web3 platforms experienced substantial financial losses due to various security breaches;

• Total Losses: Over $2.3 billion was lost across 760 security incidents, a 31.6% increase from the previous year.
• Phishing Attacks: Accounted for $1.05 billion in losses, making it the most costly attack vector.
• Private Key Compromises: Resulted in $855.4 million in losses across 65 incidents.
• Rug Pulls: These exit scams caused approximately $122 million in losses in the first half 2024.
• Legal Ambiguity: Uncertainty around the classification and regulation of digital assets can deter mainstream adoption and complicate compliance efforts.
• Global Disparities: Regulatory approaches vary widely across jurisdictions, leading to a fragmented landscape that bad actors can exploit.

Where You See Web3 Today

Crypto (Bitcoin, Ethereum, Solana)

Cryptocurrencies were the entry point. Bitcoin introduced decentralized money. Ethereum expanded this by enabling smart contracts Solana, Polygon, Avalanche, and others now power scalable, programmable economies.

Most tokens are tied to blockchains that allow peer-to-peer transfers, with no bank or intermediary in control.

What it looks like today:

• People use crypto to transfer money globally in minutes.
• Artists get paid directly without PayPal fees.
• Stablecoins like USDC are used for payroll in remote-first teams.

NFTs (Non-Fungible Tokens)

NFTs turned digital files into unique, ownable assets. Each token is recorded on-chain, proving who owns what. While 2021 hyped the art boom, NFTs are now used for digital identity, gaming, ticketing, loyalty programs, and brand engagement.

Real uses:

• Starbucks uses NFTs for its Odyssey rewards program.
• Reddit issued over 20 million NFT avatars without crypto wallets.
• Game developers issue NFT-based skins and collectibles.

DAOs (Decentralized Autonomous Organizations)

DAOs let people pool money and make collective decisions through smart contracts. Think of them as internet-native co-ops or investment clubs with rules enforced by code, not managers.

Examples in action:

• Krause House DAO raised funds to buy an NBA team.
• Gitcoin DAO funds open-source software using community voting
• Cabin DAO builds a network of co-living spaces run by its members.

Defi (Decentralized Finance)

DeFi platforms let users lend, borrow, trade, and earn interest without banks. Protocols like Uniswap, Aave, and MakerDAO run on code. Users interact through wallets; no KYC or approval is needed.

Impact today:

• Over $50 billion is locked in DeFi platforms.
• Some freelancers earn income by staking or providing liquidity.
• Decentralized stablecoins like DAI offer an alternative to inflation-prone currencies.

Web3 Social Media

Instead of giving your data to platforms, Web3 social networks let you own your profile, followers, and content. They’re built on open protocols and portable identities.

Examples live now:

• Farcaster lets users port their social graph across apps.
• Lens Protocol allows creators to monetize content directly.

Pros and Pitfalls of Web3

What’s exciting

• Ownership is real. You don’t rent access; you own assets, content, and identity.
• Transparency by default. Transactions, rules, and codes are all open and verifiable.
• Participation is permissionless. Anyone with a wallet can build, earn, and govern.

For creators, this changes the game. You no longer rely on algorithms or gatekeepers. For users, you have control and choice, not just convenience.

What’s unclear

• Scalability: Can blockchains handle millions of users without breaking? Ethereum gas fees still spike. Layer-2 networks like Arbitrum and Optimism help, but they’re new and fragmented.
• User experience: Wallets are confusing. If you lose your recovery phrase, you lose access forever. Most people aren’t ready to manage private keys.
• Regulation: Governments are still deciding how to treat crypto, DeFi, and DAOs. Some see innovation, and others see risk. The rules are inconsistent, and that scares both builders and users.
