while full nineties Network backbone Bitcoin provide, lite nodes or in the term light nodes are
made for the convenience of users in using full nodes.
These nodes, in order to apply basic activities, to the network Blockchain Bitcoins are connected. Such nodes do not download the entire blockchain to verify transactions, but only a field called Block Header. This field is only 80 bytes in size, so at the time of writing this article, when 546,412 blocks have been created in the Bitcoin blockchain network, the size of one Lite node is about 40 megabytes.
Full nodes support Lite nodes; The full node downloads the entire blockchain and measures them against the established rules of the network. Although light nodes may confirm a faulty transaction due to their limited range, full nodes do not.
Security and privacy
When you create a transaction or other service Bitcoin wallet You are using a lite node. You are connected to a third party server that connects to the full node. This third party server can access your balance information and your previous transactions! But when you use a full node directly, you don’t have to deal with these problems anymore.
Also, the use of Litenodes for transactions may cause a security breach and, as a result, damage to users; Because lightnodes do not store the entire blockchain data. For this reason, they must get their information from a third party server, which they call themselves Full Node; The creator of Bitcoin, Satoshi Nakamoto, used to avoid this method for making transactions and recommended to use full node to make transactions directly.
