Description: A malicious node is a component within a blockchain network that attempts to disrupt the normal functioning of the network or manipulate transactions for its benefit. These nodes can act in various ways, such as spreading false information, rejecting legitimate transactions, or even trying to alter the network’s consensus. Their existence poses a significant threat to the integrity and security of cryptocurrencies and other blockchain-based systems. Malicious nodes can be operated by external attackers or even by participants within the network seeking to gain unfair advantages. Identifying and mitigating these nodes is crucial to maintaining trust in the network and ensuring that transactions are processed fairly and transparently. In the context of blockchain technology, the presence of malicious nodes can destabilize the system’s balance, affecting the efficiency and security of the network as a whole.
