Layer 0

Definition ∞ Layer 0 refers to the foundational infrastructure that underpins various blockchain networks, providing the essential components for their operation and interoperability. This layer typically includes the internet protocols, hardware, and peer-to-peer connectivity that enable data transmission and communication between different blockchains. It is not a blockchain itself but the underlying technology stack upon which layer 1 blockchains are built and communicate. Without Layer 0, higher-level blockchain protocols could not function.
Context ∞ The concept of Layer 0 is gaining recognition as critical for the future scalability and interconnectedness of the blockchain ecosystem. A key discussion involves developing robust and efficient inter-blockchain communication protocols that operate at this foundational level. Future developments include advanced networking solutions, cross-chain messaging standards, and secure bridging technologies that will facilitate seamless asset and data transfer across disparate blockchain networks.
