Mar 28, · A node is nothing but a junction or IP address. To put it in simpler words; In distributed peer to peer network like Bitcoin and other crypto currencies, nodes acts as a point of intersection or connection with the network. So why wallet needs these nodes? Nodes added using addnode (or -connect) are protected from DoS disconnection and are not required to be full nodes/support SegWit as other outbound peers are (though such peers will not be synced from).

There are only two things to check that all is working. Onion addresses only route via Tor. Checking the same thing via console or CLI for getnetworkinfo , you should see for each network type the proxy info and, checking with getpeerinfo you should see that the addrlocal info is a remote address for each peer.
Onion peers do not have addrlocal and just have their onion service name for addr. The second thing to check is that your onion service for inbound Tor connections is up and all configuration is in place. Have a look in your debug. In the debug. If you are behind a restrictive firewall it may be necessary to configure outbound connections to allow Tor to connect out to other Tor nodes.

A web-based wallet requires you to trust the central node through which your transactions are broadcasted and even lightweight clients like Electrum require that you trust their servers. Running a full node of the client you support is also an indirect way of voting, which shows miners what rule set the users overwhelmingly support. Using a centralized, lightweight or even SPV wallet will never be as private as running a full node.
This is true both for online wallets and lightweight clients. SPV nodes that rely on bloom filters leak considerable information about the addresses of Bitcoin users. To less than tech-savvy users, running a full node may seem like a challenge. However, running a Bitcoin core full node is nothing more than simply downloading the latest Bitcoin core client version and running it. The Bitcoin blockchain is over GB in size, so it may take a while to synchronize your node initially. If in doubt, you can find instructions that detail the process for multiple operating systems on Bitcoin.
