description Starknet Overview

Starknet is a Layer 2 scaling solution for Ethereum that utilizes ZK-Rollups. It uses its own unique programming language, Cairo, which is designed specifically for the constraints of zero-knowledge proofs. Starknet allows developers to build highly complex, scalable applications with high security and low costs, making it a favorite for sophisticated DeFi protocols and large-scale gaming projects.

help Starknet FAQ

What is Starknet used for?

Starknet is an Ethereum Layer 2 network that processes transactions off-chain and submits validity proofs back to Ethereum. It uses STARK-based proofs to increase throughput while retaining Ethereum settlement.

What is Cairo in Starknet development?

Cairo is Starknet's programming language for writing provable smart contracts and applications. It is designed around zero-knowledge proof constraints rather than being a version of Solidity.

Does Starknet use zero-knowledge rollups?

Starknet is more precisely described as a validity rollup that uses STARK proofs. The proofs show that a batch of off-chain transactions was executed correctly before the resulting state is accepted on Ethereum.

How do Starknet contracts communicate with Ethereum?

Starknet supports Layer 1 to Layer 2 messaging between Ethereum and Starknet. Developers can declare and invoke Cairo contracts on Starknet while using Ethereum for settlement and verification.
