Node infrastructure refers to the network of computers, known as nodes, that support the operation of a blockchain. Each node maintains a copy of the entire blockchain, ensuring data consistency and security throughout the network.Nodes perform various functions, including validating transactions, mining new blocks, and propagating data across the network. Full nodes store the complete history of the blockchain, while light nodes keep only a subset of data, relying on full nodes for verification.The robustness of node infrastructure enhances the decentralization of a blockchain. A larger number of nodes can improve security, as it becomes more challenging for any single entity to control the network. This decentralized nature helps to protect against attacks and increases trust among participants.Moreover, different types of nodes, such as validator nodes and relay nodes, play specific roles in maintaining the overall functionality of the blockchain. The effectiveness of node infrastructure is vital for the scalability, reliability, and efficiency of the entire system. A well-maintained node infrastructure contributes to a healthier and more resilient blockchain ecosystem.
