Layer One Application

Definition

A Layer One application is a decentralized application (dApp) or protocol that operates directly on the base layer of a blockchain, such as Ethereum or Bitcoin. These applications utilize the native security, consensus mechanism, and transactional capabilities of the underlying blockchain without relying on off-chain solutions for core functionality. They directly interact with the blockchain’s mainnet, inheriting its security properties and processing transactions directly on the distributed ledger. This direct interaction means their operations are fully recorded on the foundational chain.
