Starknet is a Layer 2 ZK-rollup network on Ethereum that batches transactions off-chain and submits STARK validity proofs to Ethereum for finalization. The rollup inherits Ethereum security through cryptographic proof verification rather than economic challenge windows, enabling fast withdrawals once a proof is published. The network features native account abstraction, parallel execution, and Cairo as the smart contract language.
