Ethereum Layer

Definition

An Ethereum layer refers to a distinct component or network built upon or alongside the main Ethereum blockchain to enhance its capabilities. This typically differentiates between Layer 1, which is the foundational Ethereum blockchain itself, and Layer 2 solutions, which operate off-chain to process transactions more efficiently before settling them on Layer 1. Layer 2 technologies, such as rollups or sidechains, aim to improve scalability, reduce transaction costs, and increase transaction throughput without compromising the security or decentralization of the underlying Ethereum network. These layers are crucial for supporting the growing demand for decentralized applications and smart contract functionality. They represent a modular approach to blockchain architecture.
