Node: A kind of copy of the ledger that people use to track cryptocurrency transactions that occur on the blockchain. The main purpose of the nodes is to maintain the integrity of the blockchain for a given cryptocurrency. Even having a single node on a chain allows you to copy the transaction chain. The more nodes are found in a blockchain, the more secure it becomes. As the number of nodes in the block chain increases, so does the number of copies. Therefore, the blockchain register is expressed as unalterable. It is this distributed ledger technology that makes Blockchain technology much more secure than the internet.
