StarkWare develops scaling solutions for the Ethereum blockchain based on STARK Validity Proofs. It has launched StarkEx – a SaaS scaling engine, and Starknet, a Layer 2 Validity Rollup. It has also developed Cairo, a Turing-Complete Programming Language.

Starknet is a permissionless Validity-Rollup (also known as a “ZK-Rollup”) that operates as an L2 network over Ethereum. It enables any dApp to achieve scale for its computation without compromising Ethereum’s composability and security, thanks to Starknet’s reliance on a state-of-the-art cryptographic proof system - STARK.
