noun
A node operator is an individual or organization responsible for running and maintaining a node within a blockchain network. This includes ensuring uptime, software updates, security, and compliance with the network’s consensus rules.
Node operators may run different types of nodes—such as full nodes, validator nodes, or archival nodes—depending on the blockchain protocol. Their role is essential for validating transactions, relaying data, and contributing to network health and decentralization.
In some networks, node operators are compensated through rewards, fees, or staking incentives. In others, especially non-monetary networks, they may volunteer to support the ecosystem.
