StarkNet is a Zero-Knowledge Rollup (ZK-Rollup) that is decentralized, permissionless, and censorship-resistant. It supports general computation over Ethereum.  Developers create applications on StarkNet allowing users to send transactions the same way they do with Ethereum today. All StarkNet transactions are periodically batched, and their validity is proven on a stark proof, which is then verified on the Ethereum Blockchain.
