If you are new to Bitcoin and the notion of cryptocurrency and blockchain, you might wonder what is a Bitcoin node, and what it’s used for. This article will explain to you the essentials of bitcoin node, and answer your questions concerning the technology.

This makes it possible to send money around the world without censorship (personal gain) and contributes to the security and strength of the network itself (public gain).
