What is Starknet??
Starknet is a Permissionless, Valid Compilation, also known as Zero-Knowledge Compilation (ZK Compilation) for Ethereum. It operates as a Layer 2 (L2) blockchain, allowing any dApp to achieve massive scale for its computation without compromising the aggregation and security of Ethereum.
Starknet aims to achieve secure transactions with low cost and high performance using the STARK cryptographic proof system. Starknet contracts and the Starknet Operating System are written in Cairo, a specialized and custom-built programming language.
