A local node is a computer or device that connects to a blockchain network and stores a copy of the entire blockchain. By running a local node, users can participate actively in maintaining the network, verifying transactions, and sharing data with other nodes.Local nodes help enhance network security and decentralization. When more individuals run local nodes, it becomes harder for any single entity to exert control over the network or manipulate information.Running a local node usually requires some technical knowledge and sufficient storage space, as the full blockchain can be quite large. Users benefit from having direct access to real-time data without relying on third parties, thus increasing privacy and control over their transactions.In addition to providing security, local nodes contribute to the overall health of the blockchain network by relaying information and ensuring efficient communication between connected nodes. This collaboration among nodes helps sustain a stable and reliable network environment.
