What Is a Light Node?
A light node is a type of cryptocurrency wallet that does not store the entire blockchain. Instead, it only stores the most recent blocks and transactions in order to verify new ones. This makes it much faster than full nodes which must download and store every single block since the beginning of time. Light nodes are also more secure because they don’t have access to all of the data on the blockchain, making them less vulnerable to attack or manipulation.
Light nodes are becoming increasingly popular as they allow users to quickly send and receive payments without having to wait for long synchronization times associated with full nodes. They can also be used by developers who want to create applications that interact with a blockchain but don’t need access to its entire history. Additionally, light nodes require fewer resources than their full-node counterparts so they can be run on low-powered devices such as smartphones or tablets.
