A lightweight node, often referred to as a light client, is a type of node in a blockchain network that does not store the entire blockchain. Instead, it only keeps a small portion of the blockchain data, typically the block headers. This allows it to operate with significantly lower storage and resource requirements.Lightweight nodes connect to full nodes to retrieve transaction data and confirm the validity of transactions. They rely on these full nodes to provide accurate information, making them less independent but more accessible for users with limited hardware capabilities, such as smartphones or basic computers.This setup makes lightweight nodes ideal for users who want to participate in a network, send or receive transactions, and access services without needing to maintain a full copy of the entire blockchain. Consequently, lightweight nodes contribute to faster syncing times and reduced latency, enhancing the overall user experience while still providing essential functionality.
