Layer 0 is a term used in the cryptocurrency space to refer to the underlying protocol layer on which blockchain networks are built. It is sometimes referred to as “the base layer” or “the fundamental layer” and serves as the foundation for all other layers of activity related to blockchain technology.
At this level, users can access and interact with blockchains without having any knowledge of coding or programming languages. Layer 0 protocols provide basic functionality such as verifying transactions, creating new blocks, maintaining consensus between nodes and ensuring security. Examples of Layer 0 technologies include Bitcoin Core, Ethereum Virtual Machine (EVM), Hyperledger Fabric and Quorum.
Layer 0 protocols are responsible for providing secure communication between different nodes within a network by using cryptographic algorithms that ensure data integrity and make sure only authorized participants have access to it. In addition, these protocols allow for smart contracts – self-executing code snippets stored on the blockchain – to be executed securely across multiple parties without relying on a third party intermediary such as an exchange or broker.
Finally, Layer 0 technologies also provide ways for developers to easily build applications that run on top of them without needing deep technical knowledge about how these systems work internally at the low levels. This helps speed up adoption times by allowing developers from all backgrounds an entry point into building decentralized applications quickly and efficiently with minimal setup costs compared with traditional software development paradigms like server-client architectures
