BlueWallet added support for Lightning Address a few days ago. I don't think that it supports keysend payments so it's a quite surprising turn of events to me.

Proxmox should have a negligible impact on the I/O. I suspect that the USB protocol might be imposing some kind of limitation (like limited IOPS?).


No, I was using that drive with my previous Raspberry Pi build. I reused it so I didn't have to sync from the beginning. My node catches up quickly when I lose my Internet connection so I guess it wouldn't take a long time.


I can't really do that. I have a bunch of other VMs.

That's interesting. I wonder what is the bottleneck in my system then. At first, I thought that the USB SSD was the culprit but it should still be faster than your HDD. Does anyone have any idea what could be wrong with my setup?

That's exactly what it was designed for - instantaneous micro-payments. You don't need to lock up a large amount of coins on the Lightning Network unless you want to earn money off payment routing (which is not as easy as it may sound).

Both of you need to be able to use Lightning Network in some way. You can open a channel to some large node while the other person can use, for example, BlueWallet which takes care of the channel management for the user. If both of you open a direct channel to each other then you won't have to pay any routing fees. They are negligible in most cases anyway.


Yes, the receiver has to provide you a special Lightning invoice which is unique for every payment. The Lightning Network also supports spontaneous (keysend) payments but they are not that common. Also, both of you need to be online to settle the transaction.


Yes, you need a native SegWit (P2WPKH) wallet.

Make sure to check out Electrum Lightning Network walkthrough if you decide to give the Lightning Network a try. BlueWallet might be a better idea for a first-time experience since you won't have to worry about stuff like incoming/outgoing liquidity.

Sure, you can give it a try. Although, you will have to install everything manually rather than use some out-of-the-box solution.


I copied the block data from my computer. I didn't want to waste time so I started the sync while I was waiting for all parts to arrive.


Somewhere around one week. The sync was not even halfway through. It took less than a week on different hardware. See this topic.

Can you see an incoming transaction in the "History" tab?


Don't worry about it. Your transfer won't expire. The expiry time does not have any impact on coins. It is available to make it easier to track payments.

I was running LND on the Pi. I don't think it matters; It would have been hot with c-lightning as well. I don't remember how much CPU LND was using on average. I believe that bitcoind was stressing it the most.


I bought a 1 TB Sandisk Extreme USB SSD. I am still using it in my current build (I didn't want to spend any extra money on another internal drive) and it seems to be working as well as other SATA SSDs.

I also tried running ElectrumX on the Pi but I couldn't stand the noise of the fan which started kicking in even more frequently. The initial sync was taking so long that I eventually gave up.

I have been using c-lightning for quite some time now and I am really satisfied with it. I am not a developer, though. All I care about is stability and some useful features. I really like that you can easily open multiple channels via a single command (unlike LND which I believe requires user to construct a transaction manually using PSBTs). We have been also experimenting with dual-funding here.

I ran into some problems with macaroons while using LND. It's been a long time ago so I can't give you the exact details.


I also used that case (without the m.2 slot) for my build. Nevertheless, the Pi was getting quite hot very often despite the built-in fan and included thermal pads. Also, the fan is a little bit noisy above 50% of its maximum speed. I eventually moved my node from the Pi to a normal server.


Thanks! As you already know, I am working on the update of the first post. I will make sure to include this piece of information.

They are running two nodes - bfx-lnd0 and bfx-lnd1. They even have a dedicated website which shows their nodes' liquidity. Right now, they can receive ~5.4 BTC and send ~25.7 BTC via the Lightning Network.

Make sure to check out Basics of The Lightning Network and The Lightning Network FAQ. The latter one is fairly active; feel free to ask your Lightning related questions there. However, that thread contains slightly out-of-date information. I am currently working on an update. I will probably publish it at the beginning of the next week. You might also find this list useful.

It's been like that for most of the time anyway.


Yes, they are. Relay is actually what you need if you want your node to be able to work with Sphinx Chat.

There is also Sphinx Chat. It's been around for quite a while and anyone with LND node can use it. It works on the same principle as Zion and offers similar features.

Bitfinex supports Lightning Network deposits and withdrawals as well. They also maintain two fairly large and well-connected nodes (bfx-lnd0, bfx-lnd1) so payment failures should not be a real problem.

W skrócie, EIP-3554 ma za zadanie zmuszenie społeczności do jak najszybszego przejścia z PoW na PoS.


Górnicy nadal dostają 2 ETH za wydobycie bloku. EIP-1559 sprawiło, że znaczna część opłat transakcyjnych nie trafia do kieszeni górników, a jest spalana. Po wprowadzeniu EIP-1559 opłata transakcyjna składa się z base fee (które jest spalane) oraz opcjonalnie z priority fee. Aktualizacja jest dosyć skomplikowana. Base fee jest automatycznie zwiększane lub zmniejszane o 12,5% w zależności od obecnego obciążenia sieci. Może warto by było założyć o tym osobny temat, gdzie moglibyśmy to dokładnie przedyskutować?

You might also consider adding Electrum Lightning Network walkthough to your list. If someone is using Electrum as their main wallet then they might give Lightning Network a try if they see that thread. Some people might find All Lightning Network Threads In One Place useful as well.

Take a look at The Lightning Network FAQ and Basics of the Lightning Network.


Bitfinex already supports Lightning deposits and withdrawals. They have two really large nodes (bfx-lnd0, bfx-lnd1) which are well-connected. They charge only 0.000001 BTC (~$0.05) for Lightning withdrawals.

Od dłuższego czasu przypominam sobie o tym projekcie tylko raz na kilka tygodni. Wciąż trzymam to co nakopałem, ale pewnie pozbędę się większości jak cena znowu wzrośnie do okolic $0.20. Przegapiłem każdą taką poprzednią okazję.
