## When this is necessary? ## When this is necessary?
This is only necessary if: This is only necessary if you run a full node and you want to propagate locally-originating transactions over Tor (using `tx-proxy` option, see [monerod reference](/interacting/monerod-reference/#tori2p)). This allows you to mask your IP (as transaction originator) against P2P network surveillence, on top of Monero's built-in Dandelion++.

## What are P2P seed nodes? ## What are P2P seed nodes?
Your monero daemon will discover other p2p nodes but it needs to start somewhere. These starting nodes are known as "seed nodes". For clearnet the seed nodes are hardcoded in the software so no configuration is needed. Your monero daemon will discover other P2P nodes but it needs to start somewhere.

For the Tor network there are no hardcoded seed nodes. You must specify them manually by using the `add-peer` option in `monero.conf`. For the Tor network there are no hardcoded seed nodes. You must specify them manually by using the `add-peer` option in `monero.conf`.

You need Tor daemon installed and running on your laptop. You will also need torsocks command line tool that often comes with Tor. You need Tor daemon installed and running on your laptop. You will also need `torsocks` command line tool that either comes with Tor or needs to be installed separately.
### Test using torsocks and telnet
You need tor, torsocks and telnet installed.
To test speficic onion: To test speficic onion:
torsocks telnet blzchctiibfjfvtukctsydhquucz2oajnxnfc5hh4ix35gyqjhdnaqqd.onion 18080 torsocks telnet moneroxmrxw44lku6qniyarpwgznpcwml4drq7vb24ppatlcg4kmxpqd.onion 18080
