219 sats \ 7 replies \ @nullcount 21 Nov \ on: How setup a LN node with LND and i2p? lightning
https://github.com/lightningnetwork/lnd/issues/6845
LND team has more interest in adding TapASS shitcoins on LN than supporting alternate anonymity transport layers.
I agree, i2P would be a great fit for LN nodes since both require running an always online server. A big reason Tor has poor performance is that you don't have to run a "Tor node" to use/abuse Tor. You can infinitely abuse other people's nodes on Tor with zero "skin in the game".

Tor has Exit Nodes (i.e. Tor nodes that can "translate" traffic to/from a clearnet-IP address into Tor hidden traffic. However, Tor exit nodes are not used at all in LN routing.
Basically, LN has it's own "exit nodes" (i.e. LN nodes that run BOTH a hidden service address AND a clearnet address). These nodes can "translate" traffic to/from a clearnet-only node to a tor-only node for example.
So the fact that I2P has no exit nodes should not matter.

That's how I understand it. Routing nodes would be incentivized to support all available transport layers as it increases the odds they'll help route a payment between peers which don't have the same transports enabled.
Most LN nodes are Tor-only. So the demand for anonymity layers seems strong. Additionally, clearnet is difficult/expensive to setup (especially if you don't have a dedicated-IP because you're behind the ISP's NAT).
The pleb noderunners deserve a "middleground" transport with some anonymity, easy to setup, and more performant.

idk, would like an answer on that too.

why does i2p require always online, versus tor does not? if you have a link / ref handy.
also iiic, LN doesn't require always online. that's only for receiving, and even in that case I think there are easy workaround. ie: have a high availability bank custody node for when your phone is charging, and drain to phone immediately when phone node comes online.
I suppose another reason you might say LN requires "always online" is if you are trying to generate money by routing fees. You will get a bad reputation if you are flaky connected and no one will want to try to route through you.
any other considerations?

LN doesn't require always online
Technically, you're right. But in practice most LN nodes that process the bulk of payments in the network are online near 24/7
An offline node (with no watchtower) is also vulnerable to being cheated by peers.
why does i2p require always online, versus tor does not?
Similarly, it's not technically required for an i2p relay to always be online. Of course, it will only be usable (by yourself or others) if its online.
The biggest difference between i2p and Tor is that you don't have to run ANY server to access Tor. Just download a browser (run a local SOCKS5 proxy) and you'll be able to route traffic thru the network without helping to route other's traffic yourself. It's easy to get started with Tor, but you're sharing resources (relays) with hundreds/thousands of other users which can lead to poor performance or denial of service.
"require running always online server" -- probably not the best way to phrase it. Rather, using LN and i2p (directly) require running a server and most people will probably run that server 24/7
It is technically possible for hundreds of people to use someone else's i2p relay (instead of each running their own relay). But that's not "the norm" like it is in Tor.
