A Guard Node is a security feature in some cryptocurrency networks that helps protect the system from potential attacks. It is a specific type of node that is responsible for monitoring network activity and ensuring that transactions are valid and secure.
Guard Nodes play a crucial role in maintaining the integrity of the blockchain by verifying transactions and blocks before they are added to the network. They also help prevent malicious actors from attempting to disrupt the network or manipulate transactions.
In some networks, Guard Nodes are selected based on their reputation and reliability, and they are often given additional privileges and responsibilities compared to regular nodes. This can include the ability to veto suspicious transactions or block attempts to launch denial-of-service attacks.
Overall, Guard Nodes are an important component of a secure cryptocurrency network, helping to protect the system from potential threats and ensure that transactions are processed efficiently and safely.
