Most new blockchain applications are being built on [Layer 2](/layer-2) chains. Layer 2 is a set of technologies or systems that run on top of Ethereum (Layer 1), inherit security properties from Layer 1, and provide greater transaction processing capacity (throughput), lower transaction fees (operating cost), and faster transaction confirmations than Layer 1. Layer 2 scaling solutions are secured by Layer 1, but they enable blockchain applications to handle many more users or actions or data than Layer 1 could accommodate. Many of them leverage recent advances in cryptography and zero-knowledge (ZK) proofs to maximize performance and security, and some offer an additional level of privacy.
