# Vigilant Nodes In a blockchain network, vigilant nodes play a crucial role in observing transactions, detecting any malicious activity performed by nodes, and promptly notifying the block proposer about such behaviour. These nodes are incentivized with negligible rewards to discourage the promotion of malicious activities. This content provides an overview of the functions and purpose of vigilant nodes within the blockchain network. 1. **Monitoring Transactions**: Vigilant nodes actively monitor the transactions occurring within the blockchain network. They continuously analyze the transaction flow, observing the behaviour and actions of participating nodes. Through their vigilant stance, these nodes strive to maintain the integrity, security, and fairness of the network. 2. **Detection of Malicious Activity**: With their keen observation, vigilant nodes possess the ability to identify and detect any instances of malicious activity perpetrated by nodes within the network. This includes actions such as double-spending, unauthorized modifications to the blockchain, or any other behaviour that violates the established L1X protocol rules. 3. **Notification to Block Proposer**: Upon detecting malicious activity, vigilant nodes promptly notify the block proposer. By providing timely notifications, vigilant nodes ensure that the block proposer is made aware of the identified malicious behaviour, enabling them to take appropriate actions. 4. **Negligible Rewards**: To discourage the promotion of malicious activities, vigilant nodes receive negligible rewards for their watchful role within the L1X network. The aim is to avoid creating incentives for nodes to engage in or tolerate malicious behaviour. Instead, the focus is on maintaining a trustworthy and secure blockchain environment. The presence of vigilant nodes reinforces the network's integrity and security by actively monitoring transactions, detecting malicious activity, and notifying the block proposer. By incentivizing vigilant behaviour with negligible rewards, the L1X blockchain network strives to create a robust and transparent ecosystem, discouraging nodes from engaging in activities detrimental to the network's health and well-being. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
