Layer 0 refers to the foundational layer of blockchain architecture that enables different blockchains to communicate and interact with each other. It serves as the base on which Layer 1 blockchains, like Bitcoin and Ethereum, operate. This layer provides essential infrastructure, including networking protocols and resources, to facilitate cross-chain functionality. By supporting various Layer 1s, Layer 0 enhances scalability and efficiency, allowing for more seamless transactions across different networks.One of the main benefits of Layer 0 is its ability to enable interoperability among multiple blockchains, which is crucial for the future of decentralized applications. Projects focused on developing Layer 0 solutions aim to create ecosystems where various blockchain networks can easily share data and functionality, avoiding the limitations of operating in silos.Examples of Layer 0 projects include Polkadot and Cosmos, both designed to connect multiple blockchains, allowing them to work together more effectively. This interconnectedness helps foster innovation and expands the potential use cases for blockchain technologies.
