Web3 · 17 min read
The Evolution of the Web
Web1 (1991–2004) was the read-only internet. Static web pages served from decentralized servers. Users consumed content but couldn’t easily create it. The infrastructure was surprisingly decentralized — anyone could run a website from their own server, and the architecture had no central choke points.
Web2 (2004–present) is the read-write internet — social media, user-generated content, streaming, e-commerce. The user experience improved dramatically. But this era is defined by platform concentration: the data you create on Facebook, the audience you build on YouTube, the followers you accumulate on Twitter — none of it is truly yours. Platforms can delete your account without explanation, change their algorithms to reduce your reach, and monetize your data and attention at whatever rate the market allows. A handful of companies — Meta, Google, Amazon, Apple, Microsoft — control the digital infrastructure that hundreds of millions of people depend on daily.
Web3 is the proposed read-write-own internet — a version where users own their digital assets and identity, enforced not by platform promises or legal agreements, but by mathematics and public blockchains. The core insight is that blockchains enable digital ownership and digital scarcity for the first time: a digital item can genuinely belong to you in a way that no company can revoke.
Core Properties of Web3
Decentralization — Applications run on distributed blockchain infrastructure. No single entity controls the network, can censor participation, or can unilaterally change the rules. Self-Sovereign Identity — Your identity is represented by a wallet address — a cryptographic key pair you control. You log into Web3 applications by signing a message with your private key (proving you control the address), without handing any credentials to any company. No Google login, no Facebook login, no risk of your identity being revoked by a third party. True Digital Ownership — NFTs and blockchain tokens enable genuine digital ownership; if you earn an in-game item on a blockchain game, the game company cannot delete it — it exists on the blockchain. You can sell it, transfer it, or use it in other compatible games. Composability — Web3 protocols are open source at the infrastructure level. Any developer can read, audit, and build on top of any existing protocol. Uniswap’s smart contracts can be used by any application that wants swap functionality.
What Has Been Built
DeFi — The most mature Web3 category. Trillions in cumulative transaction volume across lending, borrowing, trading, and asset management protocols. NFT-Based Ownership — Digital art, gaming items, music rights, event tickets, and real estate representations as genuinely owned assets with provable scarcity. Decentralized Social Media — Lens Protocol allows users to own their social graph (followers, content history) and move it to any compatible application. Farcaster is a sufficiently decentralized social network protocol used by thousands of developers. Nostr enables censorship-resistant publishing. DAOs (Decentralized Autonomous Organizations) — Organizations governed by smart contracts and token-holder votes. Uniswap DAO controls over $3 billion in its treasury, governed by UNI token holders. MakerDAO governs the DAI stablecoin. Nouns DAO collectively purchases and manages assets. DePIN (Decentralized Physical Infrastructure Networks) — Helium uses token incentives to build a global wireless network funded by community participants. Hivemapper uses dashcam-equipped drivers to create a global street map. Render Network distributes GPU compute for 3D rendering.
Web3 Identity: ENS Domains and Wallet-Based Login
The Ethereum Name Service (ENS) allows users to register human-readable names (yourname.eth) that map to blockchain addresses, IPFS content hashes, and other records. Instead of sharing a 42-character hex address, you can say “send ETH to alice.eth.” ENS names can function as a Web3 identity layer: your ENS name aggregates your NFT profile picture, your on-chain activity, your linked social accounts, and your crypto address. Combined with Sign-In with Ethereum (EIP-4361), users can authenticate to Web3 applications using their wallet — no passwords, no data stored on servers, no breach risk for a centralized credential database.
DAOs: How Decentralized Governance Works
A Decentralized Autonomous Organization operates through a governance token and smart contracts. Token holders can propose and vote on protocol changes, treasury allocation, and organizational decisions. Votes are weighted by token holdings. Approved proposals are executed automatically by smart contracts without requiring any individual to “push the button.” This creates organizations that can operate globally, transparently, and without traditional corporate hierarchy. Real-world challenges: low voter participation (most token holders don’t vote), plutocracy concerns (large token holders dominate), and coordination difficulties at scale. Despite limitations, DAOs have proven capable of governing billions in assets and making consequential protocol decisions.
Criticisms and Limitations: The Honest Assessment
The UX Gap — Managing private keys, gas fees, and seed phrases is far more complex than using a Web2 application. The onboarding friction is significant, and most people will not accept this complexity for everyday applications until it’s abstracted away significantly. Account abstraction (ERC-4337) and smart wallets are making progress here. Centralization Creep — Much of “Web3” relies on centralized infrastructure: most dApps read blockchain state from Infura’s or Alchemy’s centralized nodes, most NFT metadata is stored on AWS or traditional CDNs, most DeFi front-ends are hosted on Cloudflare or AWS. The underlying smart contracts are decentralized, but the access layer often isn’t. Speculation vs. Utility — The majority of Web3 economic activity has been speculation — buying tokens hoping others will pay more — rather than genuine productive use. This creates financial instability and attracts bad actors. Environmental Concerns — Most relevant to Proof of Work chains; Proof of Stake networks like Ethereum have addressed this substantially.
Getting Started in Web3
The best entry point is setting up a MetaMask wallet, getting some ETH (for gas), and exploring a few protocols on a Layer 2 like Base or Arbitrum where gas fees are minimal. Try swapping tokens on Uniswap, depositing stablecoins in Aave, or minting a free NFT. Participating in a DAO discussion on Snapshot (gasless voting) gives a sense of decentralized governance without risk. Start with small amounts you’re comfortable losing entirely as you learn.
