Running a bitcoin node isn’t directly profitable like mining, instead it keeps everyone on the same set of rules. Running a node is easy and can be done on as little as a raspberry pi, an old computer (laptop or desktop), and represents—freedom, security, and decentralization.
Running a Bitcoin node offers multiple benefits, both to you as an individual and to the broader Bitcoin network. A node is essentially a computer that stores the entire Bitcoin blockchain and helps validate transactions and blocks. A node sets the rules as to what is a valid block or invalid block and acts like ‘the bank’ when verfying the blockchain discovering and ignoring counterfit blocks while accepting valid new blocks. Unlike a wallet, which is primarily for managing funds, a node plays a more integral role in maintaining the integrity and decentralization of the Bitcoin network.
Operating a node helps support the Bitcoin network’s decentralization and security. The more nodes that are distributed around the world, the harder it becomes for any single entity to censor, manipulate, or attack the network. Your participation as a node operator contributes to this decentralized structure. For example, when users in remote or censored areas have access to nodes, they gain access to the Bitcoin network without relying on central authorities.
