Light Node

Summary

A light node is a type of cryptocurrency node that does not store the entire blockchain but instead downloads only a subset of data, enabling lighter resource usage while maintaining validation capabilities.

Detailed Description

Light nodes, also known as lightweight nodes, play an integral role in blockchain networks by allowing users to participate without the burden of downloading an entire blockchain. These nodes download only the block headers and enough data to verify transactions, relying on full nodes for most of the blockchain's logic. This design allows for quick synchronization and lower storage requirements, making it easier for devices with limited capabilities (like mobile phones) to interact with the blockchain.
