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.
