Definition ∞ Validator-Less Consensus refers to a class of blockchain protocols that achieve agreement on the state of the ledger without relying on a predefined or permissioned set of validators. Instead, every participant can contribute to the consensus process, often through proof-of-work or similar mechanisms, ensuring broad decentralization. This approach aims to reduce central points of control and enhance network security through widespread participation.
Context ∞ Crypto news often discusses validator-less consensus in the context of truly decentralized networks, contrasting them with proof-of-stake systems that rely on elected or staked validators. Debates frequently concern the scalability, energy consumption, and finality properties of such systems. Understanding this concept is crucial for evaluating the fundamental decentralization and security architecture of various digital asset protocols.
