Many Web3 applications run their smart contracts on-chain but host frontends, databases and storage on centralized cloud providers, which reintroduces single points of failure.
The Internet Computer Protocol (ICP), developed by the DFINITY Foundation, lets canister smart contracts run general-purpose compute, keep state and serve web content directly to browsers, with compute paid in cycles by the canister.
Building on ICP requires understanding new concepts: asynchronous inter-canister messaging, reentrancy risks across await points, stable memory across upgrades and chain-key cryptography. Early-stage teams benefit from architectural guidance to avoid security and reliability issues.
