Pruning refers to the process of removing unnecessary data from the blockchain to improve efficiency and reduce storage requirements. In many blockchain systems, full nodes store the entire transaction history. Over time, this can create significant data bloat.Through pruning, nodes can discard older or less relevant transaction data while keeping essential information needed for operation and security. This helps maintain network speed and reduces the resources required for individuals running nodes, enabling wider participation.Pruning can enhance scalability, making it easier for newer users to join the network without needing high storage capacities. Moreover, it can lead to lower operating costs and a more sustainable ecosystem, as it alleviates the burden on node operators. While pruning significantly benefits node efficiency, it may limit certain functionalities, such as the ability to conduct specific historical queries. Nonetheless, it remains a vital strategy for managing blockchain data effectively.
