Internet Computer Basics
The Internet Computer (ICP) allows Web3 services to run 100% on-chain, providing the only platform where developers can build and users can enjoy fully decentralized applications. ICP ditches corporate cloud, insecure bridges and expensive oracles.
What makes the Internet Computer Unique?
Smart contracts serve webpages
You can open canister smart contracts directly in your browser just like regular websites.
How it worksUsers don’t need tokens and wallets
The reverse gas model enables free-to-use, truly user-friendly dapps, ready for mass adoption.

Internet Identity
The easy-to-use authentication framework that allows anyone with a WebAuthn enabled device to anonymously authenticate with Web3 services running on the Internet Computer using the WebAuthn standard.
Create Your Internet IdentityBiometric authorization
Unlock authentication with your device via FaceID, fingerprint sensor or use a YubiKey. This provides strong security, as the cryptographic key never leaves your device. No passwords are used to authenticate on ICP.
No tracking
Remain pseudonymous using the Internet Identity authentication framework, which prevents user tracking across dapps and services.
WebAuthn
Internet Identity integrates the widely used secure web2 authentication framework known as WebAuthn for maximum compatibility.

Blockchain operation that's climate friendly
Thanks to the unique architecture and novel cryptography of the Internet Computer blockchain, it can host smart contract software, data, and computation, with levels of efficiency competitive with traditional software that runs on Big Tech's cloud services. Meanwhile, it is currently tens of thousands of times more efficient than the next most efficient blockchain. Web3 projects that incorporate Internet Computer smart contracts can consequently dramatically lower their carbon footprint, and help reduce climate change.
