Web3 Deep Understanding - Expanded Project Guides
This directory contains comprehensive, deep-dive project guides expanded from the Web3 Deep Understanding project-based learning path. Each project is designed to build fundamental understanding of blockchain and decentralized systems from first principles.
Philosophy
Web3 represents a paradigm shift from centralized to decentralized systems. These projects don’t just teach you how to use Web3 technologies—they teach you why they exist and how each component works at a fundamental level.
The traditional web (Web2) has fundamental problems:
- Trust: You must trust centralized entities (banks, tech companies) not to manipulate data
- Censorship: Single points of control can deny access
- Ownership: You don’t truly own your digital assets; you rent access
- Privacy: Your data is harvested and monetized without consent
Web3 solves these through cryptographic guarantees and decentralized consensus—code that enforces rules without requiring trust in any party.
