Starknet is an Ethereum Layer 2 scaling network developed by StarkWare that uses STARK (Scalable Transparent ARgument of Knowledge) validity proofs to achieve massive transaction throughput. Unlike EVM-compatible rollups, Starknet uses its own virtual machine (Cairo VM) and the Cairo programming language, offering computational advantages for complex operations. The network supports account abstraction natively, enabling advanced wallet features and flexible transaction signing. Starknet has attracted a significant developer ecosystem building DeFi protocols, gaming applications, and infrastructure tools, with a focus on enabling applications that would be prohibitively expensive on Ethereum mainnet.
