L2 Competition

Definition

L2 competition refers to the rivalry among various Layer 2 scaling solutions designed to improve the transaction throughput and reduce fees on a base blockchain, typically Ethereum. These solutions, such as rollups (optimistic and zero-knowledge), sidechains, and state channels, compete to offer the most efficient, secure, and developer-friendly environment. Each solution presents different trade-offs in terms of security assumptions, decentralization, and performance characteristics. This competition drives innovation in blockchain scalability.
