Welcome to Cairo
A language for scaling dApps using STARKs
A Turing-complete language making it possible for all blockchain developers to harness the power of STARKs
Cairo is the first Turing-complete language for creating provable programs for general computation.
Builtins and field elements enable efficient generation of proofs.
Cairo-based systems are already in production on Ethereum mainnet
From Hello, World to the beginning
of non-deterministic programming
