Understanding the Architecture of a Web 3.0 Application (DApp)
Understanding a Web 3.0 DApp’s architecture involves replacing the centralized database and backend of a Web 2.0 stack with Ethereum’s immutable blockchain and smart contracts, while the front‑end communicates via providers, uses off‑chain storage like IPFS, queries through events or The Graph, scales with Layer 2 solutions, and leverages tools such as Hardhat, Truffle, and Remix.
