Series: Let’s create a routing LND node

Supporting this series

If you want to support this series, you can:

  • Use tippin.me to send me a tip.
  • Use Tootmoney to ask for a Lightning invoice. On Mastodon, just send a toot like ‘@OpinionatedGeek #TootMoney #send 10000’ to have it reply with an invoice QR code.
  • Send bitcoin to this address: bc1qsaampnjm5ykcpd40pstcewt75xrtfy5cxpnpdf

Not much to report. Waited for Loop to sort itself out and the forced-close channels to close and I think both have resolved themselves.

No new routing, but there are no pending channel closes and none of the channels seem to have any huge pending payments like yesterday.

I’m wondering about separating out popular channels in the report. I could maybe summarise activity at the top the same way I separate out Pending. I like the idea of the report being prioritised with the more important information at the start.

Loop problems

Some Loop Outs were still sitting at ‘INITIATED’ this morning, and I was seeing some odd behaviour in some channels:

A local balance of 489,395 sats and a remote balance of 0 sats, but with a capacity of 1,000,000 sats? Hmm. The logs showed the outgoing prepayment had failed (with an UnknownPaymentHash error...) but the main transfer seemed to be stuck in limbo.

I restarted the Loop server, and when I next ran loop monitor some of the INITIATEDs had changed to FAILED. I’d hoped this would unfreeze things and allow the main payment to roll back too but no - now the channel was force-closing!

I really don’t know what’s going on there.

If it was just this channel I’d think it might just be the other party forcing the channel closed, but I have two channels force-closing now and another one with the frozen balance like the above.

So I raised an issue about this on Github. There’s lots of log details there if you’re interested. I’d love to know what was going on.

Part of the problem is it’s hard to trace what has happened. I just don’t have enough experience tracing such things yet, but also it is awkward for the uninitiated. For instance, when you loop out you specify a channel ID like 632050960802447360. The logs don’t show this though. Logs show the hex ID like 0xc00050b4d0 (or sometimes the channel point) so searching for the channel ID you used is useless.

The logs show the full payments that were sent, so you can decode them. But they don’t appear in the list of payments (at least as far as I can tell). Should they be there? Well, one has failed, so maybe not. The other has not yet succeeded or failed (I think), so maybe not. But I don’t know for sure that they shouldn’t appear here, and if they don’t appear here I’m not sure where else I can look for them.

I need more practice at this.

So I did spend some of today trying, and I learned where more things were. But not enough to help me figure out what’s going on.

I’m reluctant to do too much else with my channels right now. I’m not sure what’s happening with some of the Loop Outs and I don’t want to confuse things further.

I did update the lntoolkit report command to retrieve and show the forwards each channel has done that month/week/day. I like the idea of this but I don’t think I’ve got the formatting right yet.

Here’s the latest report:

Series: Let’s create a routing LND node

Supporting this series

If you want to support this series, you can:

  • Use tippin.me to send me a tip.
  • Use Tootmoney to ask for a Lightning invoice. On Mastodon, just send a toot like ‘@OpinionatedGeek #TootMoney #send 10000’ to have it reply with an invoice QR code.
  • Send bitcoin to this address: bc1qsaampnjm5ykcpd40pstcewt75xrtfy5cxpnpdf

Just a short update today. Some more routing happened - 11 payments routed, but they all used the same in and out channels. Interesting to watch.

I still have too many unbalanced channels, and they tend to have cascading problems. Because they’re unbalanced in my channel, this increases the likelihood they’re unbalanced with their other channels, which means rebalancing or loop payments are more likely to fail too. So they’re unbalanced and they tend to remain unbalanced.

On one hand, I’m minded to close channels that consistently fail like this.

On the other hand, these nodes may be the ones most in need of the inbound liquidity my unbalanced channel provides.

On the gripping hand, if there’s no evidence they’re using that inbound liquidity it might be better applied elsewhere.

I still haven’t closed any channels, and Loop Out did succeed with a couple of channels today where it failed yesterday. But I am actively considering closing some channels.

Here’s the latest report:

More failures

Talking about docker and attack surfaces yesterday spurred me to remove python from some of my servers. It did not go well.

I thought removing python would remove python. I did not think it would remove the entire networking subsystem, leaving the server disconnected - and with no way to reinstall networking without access to the network. Oh well.

I had my channel backup safely stored on a different machine so it wasn’t catastrophic, but fixing it all required a bit of work. Copying the data off the (un-networked) server was the hard bit. Once I got that done - thanks Vultr! - setting up a new instance was straightforward because nearly everything was using docker. I’m glad docker made it easy to recover, but I’m still surprised that some important networking stuff has a dependency on python (somehow).

Looping

Many of my channels are still unbalanced and refuse to route anything to rebalance them. So I figured I’d try Loop Out on them.

None worked. I tried 12 Loop Outs, and all 12 failed.

Well, it’s instructive! I’m doing this experiment (in public) to try to find out what works and what doesn’t, and it certainly seems that some channels aren’t worth the effort. I’m not going to close any channels today, but I do want to think about what kind of tests I can do to determine whether channels are worthwhile or not.

Probing

One of the things I want to try is probing routes more. I’ve mentioned probing before, but it allows me to use a fake invoice to see where payments would fail if they were real.

Here’s the result of a probe to Yalls.org:

$ lntoolkit probe-routes --amount 10000 --max-routes 1 --from 632050960761552897 --to 626559999681888257 --to-pub-key 03d06758583bb5154774a6eb221b1276c9e82d65bbaceca806d90e20c108f4b1c7 --probe-all-hops

Probe failed at hop 3 with Final Incorrect CLTV Expiry

2019/05/11 14:38:23 📄 No tip to send. That's OK, I still love you! 🥰

So the payment got as far as Solidus but then failed with the error ‘Final Incorrect CLTV Expiry’. That could be a bug in my code or it could just be my graph hasn’t received an update. In any case, it shows that my channel with ACINQ works as expected, and also that ACINQ can, in turn, forward that fairly small payment.

Trying to route through a bigger payment through a different channel shows a more common problem:

Probe failed at hop 2 with Temporary Channel Failure

2019/05/11 15:55:58 📄 No tip to send. That's OK, I still love you! 🥰

‘Temporary Channel Failure’ can mean anything, but one common cause is that there isn’t enough balance at the right end of the channel to allow forwarding of funds. It looks like the channel between ‘ln.taborsky.cz’ and ‘blue 🐘’ has a capacity of 1600000 but it doesn’t have at least 100000 on the ‘ln.taborsky.cz’ side.

Or it could just be a transient error.

I’m wondering how useful it would be to use probes to various destination sites, and to do it methodically. Every night try routing a fake payment to a bunch of ‘destination’ nodes, and see which consistently succeed, which consistently fail. And try different payment sizes to get a better feel for the actual routable capacity of a channel.

Or would sending that many probes be a problem for other sites? It’s not just that I might get blacklisted (there are no blacklisting mechanisms in LND yet, but I can see the need) - I also want to be a ‘good citizen’ of the Lightning network. I don’t want to put undue stress on other nodes. But I do want to use tools to get a better idea of the actual topology of the network from my node’s perspective.

If you’ve any thoughts on this, please do let me know.

Here’s the current report - not much change from before, apart from a complete reinstall of the OS...

Docker

I mentioned docker on the LND Slack earlier today and figured I should expand on it here. Some hilarious(?) server issues mean I can’t do much else.

I use docker to run things on my ‘real’ servers - servers that are on testnet or mainnet 24 hours a day. I like the idea of it. It does take a bit of knowledge to get up and running with it, and it takes a bit more to see the point and think it’s worth doing, but it does help.

For me it makes a bunch of things easier:

  • Encapsulation of services.
  • Build-time versus run-time requirements.
  • Server maintenance and ease of migration

I’ll try to explain each of these.

Encapsulation of services

When you run your program inside a docker ‘container’, what it can do is quite limited. It looks to the program like it has the whole machine to itself - it has the OS kernel, the whole filesystem, all the network ports and so on, all to itself. It doesn’t really though - it’s all just contained in a special ‘box’. It looks like it has a filesystem, and it can read and write however it likes - but those changes don’t make it to your actual machine unless they’re in an area you have specifically mapped for that container. And it can listen on any port it likes, but they’re not your machine’s ports - if you want to actually expose one of the container’s ports to the world, you have to explicitly choose to do that.

You limit how your program can read, save and listen by running it in a container. By limiting it this way, you make it more predictable and easier to manage. (It doesn’t matter if your program accidentally or maliciously decides to listen on port 12345 - if you haven’t declared your container is to listen on that port, no traffic will get to your program.)

By looking at how the container is configured you can easily see which files or directories it can access, and which ports is uses.

Build-time versus run-time requirements

There are a lot of great tools out there for LND. But if I’m running a ‘production’ server, I want to limit its attach surface by having as little on it as possible. I don’t want to install dev tools like the ‘go’ compiler if I don’t have to. I can reduce my exposure to problems here by using containers, either ones I build myself or - better - ones validated by the projects who own the containers.

It goes beyond just dev tools like the ‘go’ compiler though. If you’ve used ‘node’, you’ll know you can sometimes get into weird versioning issues with files in your node_modules. (It’s better now than it used to be.) But if a project supplies its own docker image, you can be assured that they’ve addressed any versioning issues and supplied the versions that work - all embedded in the container so you don’t need to npm install anything. If you’ve used ‘python’ you’ll know how you have different virtual environments for different situations, but if the project supplies its own docker image it already comes with the right version of python installed and ready to run in its own container. Versioning problems are addressed by those most capable of handling them - the project team - rather than every single person that wants to deploy that project.

And since you’re running the same container as everyone else, you don’t have to worry about particular issues with a particular compiler - you are running the exact same binaries as everyone else running that container, and in exactly the same OS image and environment. The only differences between your setup and someone else’s are due to the docker configuration - usually either the networking or filesystem mappings.

Server maintenance and ease of migration

To use containers, you need to install docker. (Or something else - other container options are available.) But once you have that installed and set up, you don’t have to worry about much else.

If you want to move everything to another server, you just need to get that new server running docker and then copy across any mapped data. You don’t need to go through a litany of dependencies to install every time you want to create a new server.

In practice

How does all this work in practice with LND? Well, Lightning Labs don’t currently provide their own docker images, so you’ll have to build them yourself or use ones others have built (if you trust them). I just build them myself.

It’s pretty easy. Once you’ve got the lnd repo, you just:

cd docker

docker-compose build

Note: if you intend to run Loop with your LND server, you need to update your local file docker/lnd/Dockerfile with the changes in my pull request: Build LND subservers when building docker image.

One really neat thing here - the build itself happens inside the docker image building process, so you don’t have to have ‘go’ installed - a docker image with the right version of go is used to build the binaries, and then discarded once they’re successfully built.

Then you - somehow - push that lnd image to your server. There are a bunch of ways to do this, and the one you choose is up to you. I push to a private docker repository but you might prefer to use docker’s own free hub.

On the server, you can use the normal docker commands to run and manage the container. I usually don’t bother. These days I prefer putting things into a docker-compose.yml file, describing the containers and all their dependencies in one place.

Here’s (most of) my docker-compose.yml file:

version: '2'

services:

lnd:

command: >-

ports:

volumes:

- ./rpc:/rpc

loop:

image: my-private-container-repository/loop:latest

restart: always

command: >-

loopd

--network=mainnet

--rpclisten=0.0.0.0:11010

--lnd.host lnd.opinionatedgeek.com:10009

--lnd.tlspath=/root/.lnd/tls.cert

--lnd.macaroondir=/root/.lnd/data/chain/bitcoin/mainnet

depends_on:

- lnd

links:

- lnd:lnd.opinionatedgeek.com

logging:

options:

max-size: '10m'

max-file: '5'

volumes:

- ./home:/root

From this you can see all the command-line parameters I’m specifying, which saves me having to remember them every time.

And you can see that the only network port I’m allowing it to use is 9735. No public incoming connections to 8080 or 10009 will make it to LND.

And you can see that the only mapped filesystems are the home and rpc directories - anything in those directories is persisted to the real filesystem, anything outside those directories is discarded when the container terminates. If I want to copy this LND server to new hardware, I just need to copy the home and rpc directories.

I use Loop as well, and it requires a way to talk to LND. Launching both from the same docker-compose.yml file means they ‘share’ a network, so Loop can happily talk to LND on port 10009 with none of that traffic ever leaving the machine.

The ‘restart’ settings mean the services will run when I log off, and will restart automatically if the machine reboots. (I’ll still have the problem of unlocking the wallet though.)

Upgrading LND is then a straightforward process of:

  • Building the new docker image.
  • Pushing that docker image to some shared repository.
  • Pulling that image down to every server you want to run it on.
  • Running docker-compose down followed by docker-compose up -d

And finally here’s the latest report:

Connecting to Loop

Since I want to have channels with a few ‘destination’ nodes, I thought about opening a hefty channel with Lightning Lab’s Loop node. I think Loop use is likely to increase in time, and it’ll typically be higher payment sizes than the median. Sure, a bunch of others will likely be connected to it, but it might still be useful.

Finding that node was tricky though. Here’s one of the paths a Loop Out took:

"path": [

"02ad6fb8d693dc1e4569bcedefadf5f72a931ae027dc0f0c544b34c1c6f3b9a02b",

"02247d9db0dfafea745ef8c9e161eb322f73ac3f8858d8730b6fd97254747ce76b",

"021c97a90a411ff2b10dc2a8e32de2f29d2fa49d41bfbb52bd416e460db0747d0d",

"03fb2a0ca79c005f493f1faa83071d3a937cf220d4051dc48b8fe3a087879cf14a"

]

03fb2a0ca79c005f493f1faa83071d3a937cf220d4051dc48b8fe3a087879cf14a just doesn’t seem to exist on my graph, or 1ml.com’s. Interesting.

021c97a90a411ff2b10dc2a8e32de2f29d2fa49d41bfbb52bd416e460db0747d0d exists, with the alias ‘021c97a90a411ff2b10d’ and 33 channels. 5 of the channels are 0.16BTC - pushing the maximum channel size, and the smallest is 4million sats.

The other two nodes in the path are less interesting - 02247d9db0dfafea745ef8c9e161eb322f73ac3f8858d8730b6fd97254747ce76b is an LNBig node that was used for routing, and 02ad6fb8d693dc1e4569bcedefadf5f72a931ae027dc0f0c544b34c1c6f3b9a02b is the rompert.com node whose channel I was looping out.

So it looks like Loop uses a fronting server 021c97a90a411ff2b10dc2a8e32de2f29d2fa49d41bfbb52bd416e460db0747d0d, along with a private connection to a hidden server. I guess that hidden server is special or has special stuff hooked into it somehow.

I don’t think I’m exposing any big secrets here. Alex Bosworth tweeted about it in March apparently:

You can use the CLI to select the specific channel you want to send out of. The end destination is the Loop service. If you want to help provide liquidity the node is 021c97a90a411ff2b10dc2a8e32de2f29d2fa49d41bfbb52bd416e460db0747d0d@18.224.56.146:9735 but more nodes may be added

Let’s try opening a big channel with 021c97a90a411ff2b10dc2a8e32de2f29d2fa49d41bfbb52bd416e460db0747d0d@18.224.56.146:9735

You know what? Let’s try opening the biggest. (I plan on looping some of this out.) So, what’s the biggest I can open?

$ lncli getnetworkinfo

{

"graph_diameter": 0,

"avg_out_degree": 18.098991320666197,

"max_out_degree": 1361,

"num_nodes": 4263,

"num_channels": 38578,

"total_network_capacity": "109731573840",

"avg_channel_size": 2844408.0522577637,

"min_channel_size": "1100",

"max_channel_size": "16777216",

"median_channel_size_sat": "816675"

}

There we go - maximum channel size is: 16777216 sats.

$ lncli openchannel --node_key 021c97a90a411ff2b10dc2a8e32de2f29d2fa49d41bfbb52bd416e460db0747d0d --connect 18.224.56.146:9735 --local_amt 16777216

[lncli] rpc error: code = Unknown desc = funding amount is too large, the max channel size is: 0.16777215 BTC

Oops. Apparently channels must be less than the maximum, not less than or equal to the maximum. Oh well.

$ lncli openchannel --node_key 021c97a90a411ff2b10dc2a8e32de2f29d2fa49d41bfbb52bd416e460db0747d0d --connect 18.224.56.146:9735 --local_amt 16777215

{

"funding_txid": "8698e55a535347ba23b994c9c21dd3a3be03a744d93a3b052f94af8bb3eabed6"

}

There we go - a maximally-sized channel to provide some liquidity to Loop. I’m curious if this will get used at all. 1 million sats is the maximum Loop Out handles right now, but I don’t have many other channels that can transfer 1 million sats so for this to work I’ll need some more big channels. But small steps. I’m not in a rush.

Loop costs

I thought I’d try and figure out the costs involved in Loop Out. It may be beyond me.

Here’s a Loop Out from my channel with the swap server:

$ loop out --channel 632366520641650689 --amt 1000000

Max swap fees for 1000000 Loop Out: 61893

CONTINUE SWAP? (y/n), expand fee detail (x): x

Max on-chain fee: 29184

Max off-chain swap routing fee: 20010

Max off-chain prepay routing fee: 509

Max swap fee: 12190

Max no show penalty: 24982

And it succeeded. How much did it cost?

Well, I tried looking at the ‘Max swap fees’ output from the loop command. Looking at the source code, here are the comments on the breakdown:

  • Max off-chain swap routing fee is the maximum off-chain fee that may be paid for payment to the server. This limit is applied during path finding.
  • Max off-chain prepay routing fee is the maximum off-chain fee that may be paid for payment to the server. This limit is applied during path finding.
  • Max swap fee is the maximum we are willing to pay the server for the swap.
  • Max no show penalty is the maximum amount of the swap fee that may be charged as a prepayment.
  • Max on-chain fee is the maximum in on-chain fees that we are willing to spend.

All figures are output in satoshi, according to answers from the LND Slack chat.

It’s still not entirely clear which fees are paid when. Some of the above fees are paid if the loop is successful, some if it fails badly, and I think the most common failure results in no costs.

In any case, the maximum fee for the swap - the figure given in the initial output - is built from the detail output by:

Max fees := Max on-chain fee + Max swap fee + Max off-chain swap routing feeMax off-chain prepay routing fee

But it’s still a ‘maximum’ threshold figure - if the costs rise above these the transaction is cancelled. This doesn’t give a good picture of the likely costs.

I’m even more confused by the ‘Max off-chain swap routing fee’. In my run above, it’s 20010 sats! That’s a very, very big routing fee for a Lightning payment. When I asked in Slack I was told ‘it’s a hard limit, you won’t pay anywhere near that, but we need a hard limit so we know when to bail out’.

So how much did it actually cost? Well, unless there’s something else going on, I figure I can look at how much was sent out, and how much came back, and the cost will be the difference in those two figures.

So, what went out? Two payments:

How much went out?

= 1010161 sats

What came back? One on-chain transaction:

{

"dest_addresses": [

"bc1qfdszj6ldrenwpd4f4s0a2326snaevwjryedk9j"

]

}

How much came back?

990218 sats

The total cost to me for this loop is the difference between those two figures:

1010161 - 990218 = 19943 sats

19943 sats is a lot less than the 61893 sats quoted as the ‘Max swap fees’ before agreeing to the run, but at $1.22 in today’s terms it’s still hefty.

I do wish I had a better handle on exactly which of the max fees are paid under what circumstances, and how loop arrives at the figures. A ‘Max off-chain swap routing fee’ of 20010 sats is an awful lot higher than the 2 sats actually paid in routing fees. So much so that it has me doubting I know what’s actually going on there.

More channels and rebalancing

I want to open a few channels with smaller nodes as well - they can be the ones most in need of liquidity. I don't know how beneficial this will be for routing, but that's why I'm experimenting in public. If it doesn't work, I can close channels as easily as open them.

I offered to open channels for folks on the LND Developer slack and 'kornpow' and ‘tongokongo’ both replied with connection details, so:

$ lncli openchannel --node_key 03077d02d11d2ade200c7fc5ba4fc66c1c599424fb945e88b3896fee6eedc07147 --connect 64.99.228.35:9735 --local_amt 1000000

{

}

$ lncli openchannel --node_key 03d40870a931fe2e978f01b26117b64d15d68119f2840c30f1b69b59955b1e7846 --connect 157.230.224.221:9735 --local_amt 1000000

{

}

One of the plans I had with my channel with the Swap server was to loop out some of the funds there and allow me to rebalance multiple channels into that new space. Instead of looping out from each channel individually, I could do fewer loops and just pay Lightning routing fees to rebalance channels.

It’s not really working out.

Probes are failing before it even gets to the swap server:

I knew some nodes would have difficulties routing but there are a surprising number of failures like the above.

Probing is handy though! I think the output (above) could use a little work - Hop 3 and Hop 4 didn’t really fail, the payment didn’t reach them because it failed at Hop 2. I think I need to make that clearer. In fact I should maybe probe from the source to the destination instead of back from the destination to the source - that would be faster and I could show Hop 3 and Hop 4 above as ‘untried’ instead of ‘Temporary Channel Failure’.

I’d also like a way to automate this probing, to give an indication of how well a channel can route. Then I could run another (nightly?) report showing which channels were useless and should be culled.

Series: Let’s create a routing LND node

Supporting this series

If you want to support this series, you can:

  • Use tippin.me to send me a tip.
  • Use Tootmoney to ask for a Lightning invoice. On Mastodon, just send a toot like ‘@OpinionatedGeek #TootMoney #send 10000’ to have it reply with an invoice QR code.
  • Send bitcoin to this address: bc1qsaampnjm5ykcpd40pstcewt75xrtfy5cxpnpdf

Fees

Now I want to spend some time looking at the fees I charge for routing. Up to now I haven’t changed any fees from the default.

I want my node to be ‘good value’ but I don’t want to undercharge.

BitMEX have a great article on routing fees.

Unfortunately they’re traders and talk about basis points so I’ll have to try to translate from what they say to the actual values lncli expects.

To help me translate, they say:

Base Fee
This is expressed in thousandths of a Satoshi.

For example a base fee of 1,000 is 1 satoshi per transaction.

and:

Fee Rate
This is expressed in millionths of a Satoshi transferred.

For example a fee rate of 1,000 is, 1,000/1,000,000, which is 0.1% of the value
transferred through the channel. Equivalent to 10bps.

As for optimal values they say:

The base fee was 0 across the period

and:

The daily fee income appears to quickly accelerate as one increases the fee rate from 0 till around 0.1 bps. Once the fee is increased above this rate, average daily fee income appears to gradually decline. Therefore, based on this experiment, it appears as if the revenue maximising fee rate is around 0.1 bps...

To translate that, if 10bps is 1,000 then a fee rate of 0.1bps is 10, i.e. 10/1,000,000. lncli expects this in sats, not millionths-of-sats, so 10/1,000,000 is 0.00001.

A base fee of 0 seems a bit scary to me, given that channels open with a base fee of 1000 by default. I can see why it would simplify the research for BitMEX but is it a good practical idea? I honestly don’t know. (I note that the channel I opened with them has a base fee of 1 though, rather than 0.)

So I’ll give it a go. Let’s try setting a base fee of 0, a fee rate of 10 and no change to CLTV delta, for all my channels:

$ lncli updatechanpolicy --base_fee_msat 0 --fee_rate 0.00001 --time_lock_delta 40

Just to verify things, here’s how my channel with BitMEX looks now:

$ lncli getchaninfo 631655136611991552

{

"channel_id": "631655136611991552",

"chan_point": "c8fbb6e78f26bd5f63419c172384b79a1209478dd30184b68711c6d1f916b1be:0",

"capacity": "1000000",

"node1_policy": {

"time_lock_delta": 40,

"min_htlc": "1000",

"fee_base_msat": "0",

"fee_rate_milli_msat": "10",

"disabled": false,

"max_htlc_msat": "990000000"

},

"node2_policy": {

"time_lock_delta": 40,

"min_htlc": "1000",

"fee_base_msat": "1",

"fee_rate_milli_msat": "10",

"disabled": false,

"max_htlc_msat": "990000000"

}

}

So the settings look as I intended. Whether or not they’re useful remains to be seen.

I intend to have a ‘default’ set of fees for channels, with other fees used to encourage or discourage behaviour. For instance, if I have a large unbalanced channel to a ‘destination’ node, I may lower the fees (or even make it free) in order to encourage its use until it’s more balanced.

Rebalancing

One of the payments I routed unbalanced one of my channels, and that gives me the opportunity to rebalance it from one of my over-full channels.

Here’s the before state - rompert is getting a little low, and Saggitarius is still full from when I opened it:

Too many carrots in rompert, too many kiwis in Sagittarius! (I do love those glyphs!)

Now let’s run this command to move 300,000 from the Sagittarius channel to the rompert channel:

$ lntoolkit move-balance --from 632050960773152769 --to 631590265456623616 --amount 300000

The balance of kiwis to carrots looks a lot healthier now!

Mystery node

Now let’s go back to that mystery node that opened a private channel with me.

I’ve updated lntoolkit to cope with private channels as a source or destination now, although I worry it’s a bit of a hack. Programming question: if I have an actual Channel object, how can I best get a ChannelEdge object. This is what I have but it seems quite hackish:

&lnrpc.ChannelEdge{

Capacity: channel.Capacity,

ChanPoint: channel.ChannelPoint,

ChannelId: channel.ChanId,

LastUpdate: 0,

Node1Pub: cef.MyPubKey,

Node1Policy: &lnrpc.RoutingPolicy{

Disabled: false,

FeeBaseMsat: 0,

FeeRateMilliMsat: 0,

MinHtlc: 0,

TimeLockDelta: 0,

},

Node2Pub: channel.RemotePubkey,

Node2Policy: &lnrpc.RoutingPolicy{

Disabled: false,

FeeBaseMsat: channel.CommitFee,

FeeRateMilliMsat: channel.FeePerKw,

MinHtlc: 1,

TimeLockDelta: channel.CsvDelay,

},

}

Anyone have any better ideas?

Anyway, I thought I’d try running auto-balance on that mystery channel to try to fill it a bit. auto-balance should try to fill the --to channel to 50% from all the currently full channels:

$ lntoolkit auto-balance --to 631605658598703105 --amount 500000cd src/lntoolkit && /Applications/Xcode.app/Contents/Developer/usr/bin/make install

So, it didn’t work. It seems none of my full channels can route anything to it.

Is it worth keeping it around if it can’t route? That’s a good question. One of the things I’m trying to do here is put together my own rules of thumb for what to do in these situations (or learn from others!) In absence of anything else, I’ll leave it open a while longer - it has already routed some funds from them, so it’s not the most useless channel I have.

Opening the channels I couldn’t yesterday

}

NSCasa just failed to connect. Oh well. I got a different node from 1ml’s visualiser:

}

A few more payments routed

I routed a few more payments since yesterday. I think. Fees show something but fwdinghistory doesn’t:

lncli fwdinghistory

{

"forwarding_events": [

],

"last_offset_index": 0

}

I’m curious what’s going on here.

Probing routes

I did a bit more work on ‘probing’ - sending a pseudo-invoice to a destination to see if it gets there successfully (if it does, it fails with a particular error that we can look for). This allows us to see if every node on the path can route the payment without us actually having to make the payment.

What’s more, if it fails you can do it using progressively shorter paths to find out exactly which node is failing to route the payment.

I think this is pretty cool!

I’ve been working on a probe-routes command for lntoolkit, and it’s at the sortof-working stage. Here’s the result of probing a path from my node to yalls.org:

$ lntoolkit probe-routes --max-fees 100000 --amount 100000 --max-routes 1 --from 632050960802447360 --to 631722206824824832 --to-pub-key 03e50492eab4107a773141bb419e107bda3de3d55652e6e1a41225f06a0bbf2d56 --quiet

Here’s how it looks when it fails. Let’s try another route, this time to LivingRoomofSatoshi.com:

Probe failed at hop 2 with Unknown Error - FinalIncorrectCltvExpiry

You can see the first failure in the path was ‘FinalIncorrectCltvExpiry’ - this may be due to a change in CLTV on that node that hasn’t propagated to my node yet, or it’s a bug in lntoolkit. In any case, you can see which node is causing the problem and can choose to take that information into account when opening or closing channels.

The pathfinding code I wrote for lntoolkit works with channels, rather than nodes - that’s usually what I want for moving balances around. It doesn’t work so well here - I’d rather not have to specify the channels in the probe-routes command. I’d have to update my pathfinding code for that, but, y’know, not today.

I have put the latest code into the LNToolkit docker image (testnet only) if you want to try it out.

And finally, here’s the latest report:

Series: Let’s create a routing LND node

Supporting this series

If you want to support this series, you can:

  • Use tippin.me to send me a tip.
  • Use Tootmoney to ask for a Lightning invoice. On Mastodon, just send a toot like ‘@OpinionatedGeek #TootMoney #send 10000’ to have it reply with an invoice QR code.
  • Send bitcoin to this address: bc1qsaampnjm5ykcpd40pstcewt75xrtfy5cxpnpdf

More channels

Let’s open some more channels.

I’m still trying to achieve a balance between reach and necessity, but I’m not sure how best to achieve that balance.

I’d like to have some more connections to nodes that will expand my reach - make more nodes available in just a couple of hops. Moneni’s NodeMatch still looks like a good tool to help here.

I’d also like to hook into under-served clusters of nodes. They’re the ones that actually need liquidity and are the ones I most want to help. But I don’t know how to find such groups. I don’t want to just pick random nodes that have few connections - that way seems like it would just end with under-used channels.

So I’m going to open 10 channels at 1million sats each - 5 from Moneni’s NodeMatch list, and 5 underserved clusters.

NodeMatch for my node is dominated by LNBIG nodes. I’ve removed them all from this list because:

  • I think opening a channel with more than one of them would make all the others in the list disappear. (LNBIG’s nodes are all interconnected.)
  • I’m kinda hoping LNBIG will open a channel with me at some point, since they usually open a channel with everyone.

So with LNBIG removed, here are the top 5 NodeMatches:

Rank 1. Sagittarius A (Would add 397 more nodes with two hops , 1508 more nodes with three hops , 2251 more nodes with four hops)
Rank 9. ACINQ (Would add 269 more nodes with two hops , 1218 more nodes with three hops , 2303 more nodes with four hops)
Rank 10. 1ML.com node ALPHA (Would add 254 more nodes with two hops , 1137 more nodes with three hops , 2301 more nodes with four hops)
Rank 17. LightningTo.Me (Would add 231 more nodes with two hops , 1290 more nodes with three hops , 2268 more nodes with four hops)
Rank 21. ln.BitSoapBox.com (Would add 219 more nodes with two hops , 1339 more nodes with three hops , 2213 more nodes with four hops)

I’d love to have an automated way of finding good clusters of nodes to connect with, but the best way I’ve found so far is to load up a Lightning Network visualiser and try to spot them by eye. If you know of a better way, please do let me know!

I loaded 1ml.com’s visualiser and tried to spot nodes away from the centre that had more than 20 channels but fewer than 50. Plenty to choose from, but here’s my selection:

So most of my wallet balance is now tied up as inputs to transactions that haven’t been added to any blocks in the chain yet. Oh well. I guess I’ll pause there for the day.

Autopilots

Rene Pickhardt has implemented autopilot functionality for c-lightning. It can use the following heuristics:

  1. Random: following the Erdoes Renyi model nodes are drawn from a uniform distribution
  2. Central: nodes are sampled from a distribution proportional to the betweeness centrality of nodes
  3. Decrease Diameter: nodes are sampled from distribution of the nodes which favors badly connected nodes
  4. Richness: nodes with high liquidity are taken and it is sampled from a uniform distribution of those

I like the idea of those heuristics!

LND has autopilot functionality but it’s not yet recommended for mainnet. As far as I can tell, it uses ‘BOS scores’ as an opaque scoring mechanism for nodes, where higher numbers are better. I’ve no idea what the BOS score of my node is though (it doesn’t appear on either of the sites that say they’ll tell you your BOS score) or what the BOS scores of other nodes are.

I do worry that everything is trying to do too much though. One of the reasons I’m writing lntoolkit is as a reaction to all the monolithic code that’s appearing. An autopilot for LND is a good idea, but does it really need to be built in to LND? Why not just have a separate program that calls into LND? Keep that program simple, keep LND simple.

Maybe it’s just me that likes the predictability of having an autopilot with specific, configured heuristics and boundaries that runs as a cron job and calls LND’s public API. I think predictability is far too unappreciated these days.

Finally, as usual here'’s the current report:

A successful loop out

Just before I headed out for the day yesterday I tried one more loop out.

I guess any payment that goes through Lightning can be subject to transient problems.

Anyway, getting 500,000sats liquidity on my channel with ln1.satoshilabs.com cost me about a max of $2.29.

First payment routing

I routed a payment!

I wasn’t expecting this to happen quite so soon, given the lack of balancing, but I routed a payment!

$ lncli fwdinghistory

{

"forwarding_events": [

{

"timestamp": "1556970764",

"chan_id_in": "631605658598703105",

"chan_id_out": "631590265456623616",

"amt_in": "96416",

"amt_out": "96415",

"fee": "1",

"fee_msat": "1096"

}

],

"last_offset_index": 1

}

So it came in on channel ID 631605658598703105 (node name: ‘03f175627ecd2b736fdd’) and went out on channel 631590265456623616 (node name: ‘rompert.com🔵‘) and it earned me just over 1 satoshi - or $0.0000572695 at today’s prices. Not much but it’s a start!

Mystery channel

Speaking of my channel with node ‘03f175627ecd2b736fdd’, when I try to move funds to the channel I didn't open, I still get the error:

$ lntoolkit move-balance --from 631655136611991552 --to 631605658598703105 --amount 500000

2019/05/05 11:32:52 🚨 Exiting with error: finding 'To' edge: could not find ChannelEdge with channel ID '631605658598703105'

After much too long, I realised that it’s a private channel (erm, sorry for disclosing it if that’s a problem for whoever opened it here but the cat was out of the bag yesterday and I did say I was going to be transparent...)

So it looks like this is a bug in lntoolkit, that it won’t work with private channels right now. I guess I’d assumed that the channel graph would contain all the edges my node knows about, not just all the public edges. I guess there’s a good reason for the current behaviour though, so I’ll need to find a way for lntoolkit to work around it - it shouldn’t place an unnecessary restriction on the --to or --from channels being public.

More loops

Trying today I had more success with loop. I figured as a starting point I’d try to loop out about 50% of the funds in my filled channels and see how many succeeded. Most did.

Well, there you go. Most channels are now balanced, but there aren’t very many channels yet. And looping out is comparatively expensive (although I’m not sure I’ve fully understood the true costs yet). I don’t plan on doing much looping, but I think it was important to get most channels balanced from the beginning. I hope soon I’ll be able to balance channels people open with me using channels I open myself - if you want me to try this with your node, now’s the time to open a channel!

Here’s the current report - just 2 unbalanced channels now:
