DApps (Decentralized Applications) are the backbone of Web3. Unlike traditional web services (like Twitter or YouTube) run by corporations, DApps run autonomously on decentralized blockchain networks. We explain their mechanisms.

Core Features of DApps

1. Absence of Central Control

Codebases and smart contracts are open-source. Apps cannot be shut down arbitrarily due to corporate insolvency.

2. No Sign-up / Login Friction

Instead of registering emails and personal data, users unlock services simply by connecting a Web3 wallet.

3. Censorship Resistance

User transaction logs are recorded on decentralised chains, shielding data from arbitrary corporate moderation or deletes.

Notable DApps

• Uniswap: A decentralized exchange allowing token swaps mediated purely by automated smart contracts.
• OpenSea: A global bazaar for minting, listing, and trading NFTs directly between users.
• Axie Infinity: A pioneer Play-to-Earn gaming title that popularized digital asset rewards.
