The word “node” in computer science simply refers to a component in a bigger network. A node is one of the participants that runs the blockchain’s software to validate and preserve the whole history of transactions on the network.
Since the blockchain network consists of thousands of computer nodes dispersed over the globe, crypto is a peer-to-peer, distributed economic system.
A communication channel exists between each blockchain node in the network. There are various types of nodes, each in charge of carrying out a particular set of tasks.
