Thus, node and full nodes are different to each other. A nodes is simply a connection of each transactions that exchanges blockchain on to make it updated everytime. Full node is a device that holds or has a copy of all the transactions on blockchain

A node is basically a copy of the blockchain stored on your system which updates with every new transaction. Nodes are stacked next to each other and are divided into 4 types.

A Node is a network that can be a computer or a device that is attached such as a printer. In Blockchain Nodes are connected to each other by exchanging the latest blockchain data and keeps upto date. A full node can be called when it contains full history copy of blockchain transaction.

To make it simple a node is any system or device connected to a network, computer is a good example. Nodes serves as the connection or the stem where data is transferred from one end to another.

The concept of a node is something that is connected in to an entity. In a network, node mostly refers to the routers, computers, bridge and etc. But it blockchain, nodes are those that stores the data of the blockchain, and constantly exchange the updated data to one another. Nodes, are the home of blockchain.

To explain what nodes are, I will first like to define what a node is.

A node is basically a point. when more than one of these points intersect or connect to each other, it's then called a network. So you can consider networks as points (nodes) connected to each other.

To better understand it, The internet is made up of nodes – a network of millions of other computer connected together for the sole purpose of sharing information.


That said, Nodes in blockchain represents a collection of points or copies of the blockchain that are distributed across everyone using it. Together, these nodes form a network.

This is why people consider more nodes === a stronger network.
