Node Autonomy

Definition ∞ Node autonomy describes the independent operation of individual participant computers within a decentralized network. Each autonomous node maintains a complete or partial copy of the blockchain ledger, independently verifies transactions, and contributes to the network’s consensus mechanism without requiring central coordination. This operational independence is a foundational characteristic ensuring censorship resistance, security, and the overall decentralization of a distributed ledger technology. It minimizes single points of failure and prevents external control over network operations.
Context ∞ Node autonomy is a persistent ideal in blockchain design, with ongoing efforts to reduce hardware requirements and technical barriers to participation, thereby increasing the number of independent nodes. News often covers discussions around the decentralization metrics of various blockchain networks, frequently focusing on the number and distribution of autonomous nodes. Concerns about increasing centralization due to high hardware costs or concentrated staking power are common topics. The pursuit of greater node autonomy is a central theme in protocol upgrades and community discussions aiming to strengthen network resilience and security.
