Quick Start

Become a “World Computer” developer who builds sovereign social media, games, enterprise apps, AI, Web3, DeFi and _
The Internet Computer (ICP) provides a 100% decentralized platform where devs can build without Big Tech and traditional IT.
End-to-end decentralization makes services immune to cyber attack, unstoppable, censorship-resistant, and optionally tokenized and autonomous.
