Layer 1 blockchains are the foundation of the entire crypto ecosystem, representing the core innovation and competitive focus of blockchain technology. As Ethereum successfully transitions to proof of stake, eco-friendly public chains emerge, and Layer 2/Layer 3 solutions develop in parallel, the Layer 1 space is undergoing a profound reshuffle. This article highlights 15 noteworthy Layer 1 projects, evaluated based on their ecosystem popularity, market capitalization, on-chain activity, and native token performance.
What is Layer 1 Blockchain?
Layer 1 (base layer) is the underlying network of a blockchain, where all transaction finality and recording are completed. Unlike Layer 2 solutions built on existing blockchains, Layer 1 protocols are independent networks with their own consensus mechanisms and security models. These networks are crucial for achieving decentralization, security, and transparency.
