Nodes receive this information as an incoming connection and acting as intersections, they re-transmit them to other nodes as outcoming connections. In other words, iis are required to get the message propagated in the network. Most importantly, they enforce Bitcoin consensus rules in the network. When a new block is propagated in the Blockchain, the information is thereafter broadcasted from node to node, in order to confirm that consensus rules were followed. If a node validates it, the information will be stored and then relayed to every other node it is connected to; otherwise, it will get rejected. These are called validation nodes, and they are necessary for the completion of transactions in the Blockchain. For example, they confirm that blocks are not larger than 1MB, that the transaction signatures are valid in the correct data format or, see more blocks create the defined number of new Bitcoins.
