A watchdog node is a specialized type of node in a blockchain network that actively monitors and protects the network’s operations. Its primary function is to ensure the integrity and security of transactions and the overall protocol.These nodes often serve as overseers, helping to detect malicious activities or any deviations from expected behavior. When a potential issue is identified, such as double-spending attempts or other fraudulent actions, the watchdog node can alert the network or initiate corrective measures. Additionally, watchdog nodes can contribute to governance by monitoring compliance with network rules and protocols. They may also participate in decision-making processes, ensuring that the network remains decentralized and fair.By maintaining oversight, watchdog nodes enhance the resilience and reliability of the network, providing users with confidence in the system’s security and operational stability.
