eer-to-peer connections over other, faster peer-to-peer overlay networks, not the Tor network. The Onion Service can function as the "rendezvous" server for making peer-to-peer connection outside of Tor. Tor's Onion Services can be used to exchange IP:port information for making direct connections over the internet without using Tor. No need to use commercial third parties. Ngrok, Tailscale, etc. all require use of servers run by a commercial third party. Tor does not. There is ample free software that can establish peer-to-peer connections over the internet but in every case it requires some reachable server running this software on the internet, and for most users that means they have to run a server and pay a commercial third party for hosting. Tor has no such requirement. Imagine being able to share content with family, friends, colleagues without the need for so-called "tech" companies^1 acting as intermediaries ("middlemen"). With a reachable IPv4 address this becomes possible. It would be nice if every home internet access subscriber received a reachable IPv4 address from their ISP. No doubt, some do. But on today's internet most do not. The so-called "tech" companies all have reachable IPv4 addresses. Hence they assume the roles of middlemen and use this position to exploit internet subscribers for profit. Something like Tor provides a solution. Again, it is not always necessary to route all traffic over Tor. Tor can have other uses. When the goal is simply peer-to-peer connections, Onion Services can be used to bootstrap peer-to-peer overlay connections using the user's choice of software by providing a secure, reliable way to exchange IP:port information. Goal here when using Tor is not anonymity nor censorship evasion, it's reachability. Similarly, goal of peer-to-peer is not necessarily anonymity nor evading censorship either, it's bypassing commercially-motivated, eavesdropping middlemen known as "tech" companies, and avoiding the annoyances of advertising. A possible additional benefot of using Tor in this way is elevated privacy. Google, for example, cannot easily discover Onion Services. No one can discover Onion Services using ICANN DNS. 1. The term "tech" as in "tech company" means a company, usually a website, that collects data from and about people to support the sale of advertising services because advertising services are the only services the company can sell on a scale large enough to sustain a profitable business.

It can also be used to expose individual files and allow you to request them from another computer. Why not just use ngrok? ngrok is nice. But it requires everything to go through a central authority (a potential security issue), and imposes artificial restrictions, such as a limit of one TCP tunnel per user. It also doesn't allow you to expose files easily (you have to set it up yourself)." https://github.com/ethan2-0/onion-expose As another Github contributor put it: "With onionpipe, that service doesn't need a public IPv4 or IPv6 ingress. You can publish services with a globally-unique persistent onion address, and share access securely and privately to your own allowlist of authorized keys. You don't need to rely on, and share your personal data with for-profit services (like Tailscale, ZeroTier, etc.) to get to it." https://github.com/cmars/onionpipe https://news.ycombinator.com/item?id=36734956 https://news.ycombinator.com/item?id=30445421 https://news.ycombinator.com/item?id=29929399 "Finally, onion services are private by default, meaning that users must discover these sites organically, rather than with a search engine."
