Well thats ok, But i am trying to understand Why Tor node is required ( For Privacy

) thats what all i know about it as First time I'm actually Getting it in a way that how it is used and what are the reasons tha we should use it.
Data sent through the TOR network is obfuscated by the relay nodes (on the TOR network, not the Bitcoin network), to the hidden service - that huge jumble of letters inside an .onion domain name, and in this case points to another Bitcoin node - and then back again to the Tor client, in this case, the Bitcoin node.
When you use IP addresses, the data is sent in plain-text because it's not encrypted with TLS first.
