Not sure what is meant by "anonymously" but you would be putting your IP address up in the Directory list (thats just how Tor currently works). For example, @C_Otto shared his Tor relays in the post above #609650

A really cool goal to work towards is to popularize more use of "Tor Hidden Services". Right now its hard to visit a .onion site because the names are not human readable. For example in "Clearnet" if you goto https://google.com it looks up via DNS the ip address 142.250.114.100.

It would be cool to build a similar human readable naming system for "short onion addresses". For example mapping stackers news onion address http://snsnsnya6h3ot563f3p566wuhfoklkg5f62hokdlaqzcaub3gf4xlxyd.onion to something like http://crazyhorse69.onion.

There are several ways to do this, but it would be nice to do it in a decentralized way. Bitcoin is decentralized and we all already own sats. So maybe we could create a deterministic list of words (and maybe a few numbers) to create a "gamer tag" like crazyhorse69.

The deterministic list can be an imaginary overlay, ordinally ordered list, that maps each "gamer tag" to a single satoshi (sort of like the original ordinal theory that Casey pitched) but with more human readable names. We would simply just need to mash up enough words (and a few digits) to make 2.1 quadrillion "gamer tags" that map to each individual satoshi. (sort of like we have a standard list of words that go into your BIP-39 seed phrase https://github.com/bitcoin/bips/blob/master/bip-0039/english.txt)

Then anybody who already owns satoshis already has a basket of "gamer tags" they can choose. They they can simply sign a message with that key for the mapping. Really anything can be mapped. Doesn't just have to be onion addresses
