I dont know if this is the right place to ask, but the way i understand it is, that we always transmit raw data at the limit (With error correcting, formating etc) and that the technical problem is to reduce the effect of error correcting to increase efficiency and to come closer to the capacity. Is this correct?
I've got a pretty cheap budget laptop (Lenovo Ideapad 3 14are05) and it has a relatively decent CPU (Ryzen 4300u) but only 4gb of 2666mhz ram soldered to the board. There is a sodimm slot for upgrade. I'm pretty sure I could use more ram for daily tasks and for my university work, but I'm not sure if I shud make it 8gb or 12gb.
If I upgrade it to 8gb (4+4) it'll be dual channel right, but in 12gb (4+8) it will only be single channel?
Will there be a noticeable benefit for having dual channel on such a budget laptop? Or is more capacity better?
My main tasks are general everyday multitasking, chrome, and compiling c++ code for uni.
Thoughts?
Thanks

I often have Channels where the only calls to send that occur are the last step of a coroutine, with the coroutines receiving from the Channel running in the same CoroutineScope.
In this case, the capacity of the channel doesn't matter.
If it is UNLIMITED, send always succeeds and the sending coroutine immediately completes.
If the capacity is RENDEZVOUS (0) with onBufferOverflow = SUSPEND (the default), then the sending coroutine waits for a matching receive but this doesn't make a difference since nothing happens in that coroutine after the send and nothing is waiting for it to complete.
So should I use RENDEZVOUS or UNLIMITED in this case? Which will incur the least overhead?
This is a tutorial showing how to deploy 12M sats of liquidity on your brand new LN node, using only one onchain transaction that will lead to the creation of 10 channels with 20M sats capacity and a good anount of inbound liquidity. Of course, these numbers are just used as an example.
Warning: This tutorial is using advanced features of Electrum Desktop and balanceofsatoshi (bos), make sure you feel very comfortable with and understand each step before doing it with your sats, as some mistakes might lead to a loss of funds.
Ingredients:
- LND node
- balanceofsatoshi
- Electrum Desktop (edit: or also Sparrow Wallet, tutorial here)
- 12M sats in your cold wallet (as an example here, could be anything of course)
- Lots of love, always needed
Receipe:
- Do not send sats to your LND wallet on your node! (you're saving one onchain transaction). (Edit: except if you want to open anchor channels, in that case you need at least 1 UTXO with a minimum of 100k sats in your LND on-chain wallet for the anchor channel opening process to succeed).
- Negotiate to be part of four 2M sats triangle on this sub. Make sure you let your peer know of your plan as they might be worried that you are a new node with no channels yet!
- Four triangles will link you to 8 'routing' peers, try to make sure that at least a couple of them are 'good node' on Terminal Web. The goal is to have at least 3 good peers, but you'll get some in the next step.
- Find 2 big 'merchant' node (e.g. exhange, merchant, wallet etc). Try to read Reddit or TG LN threads to find good nodes that will probably be quite active. Note that some of them have minimum channel size so they might not be suitable for a 2M sats channel. Take your time to read and get information to try selecting good merchants. But in the hand, it's also a question of luck! Try to get merchants that are 'good nodes' with 5 green ticks in Web Terminal.
- In in text file, make a list of the pubkeys of all the nodes you will open to (i.e. 4 peers as part of the triangles and 2 merchant peers = 6 pubkeys)
- *Batch open transaction with balanceo
I'd like to build a strong node that maximizes earnings for the future. Say I have 1BTC that I'd like to invest into my node.
Should I aim for 100 channels of 1m capacity each, or 30 channels of ~3.33m capacity each?
I open a channel/triangle the capacity is 5M sats each, it gets rebalanced, and then we do a lot of traffic. Where do the fees show for the channel? Is it possible for the channel to grow its capacity due to fees? Is it possible to increase the channel capacity without closing it?
Thanks in advance,
If you had 3 BTC to add to the network, would it be best to open 3, 30, or 300 channels? I don't want to spend millions of dollars on on-chain channel-opening fees.
Is there any benefit (to the network as a whole) to create 3x 1+ BTC channels? Or theoretically, a 3 BTC channel?
Secondary question: LN in Electrum has a "Max" button on the channel-open dialog. If you click that, it prefills the previous maximum (0.16... BTC), however it will still let you manually type something more, like 0.5 BTC. Anyone here use Electrum for their LN wallet?
Is it possible to increase the capacity of existing channels? Would I have to close and reopen the channel? Obviously that is not desirable because of fees.
