- From node A, I have opened a channel with 1ML in testnet. (electrum node) - From node B, I have opened another channel with 1ML in testnet. (c-lightning node)
- From node A, I can send about 0.02 and receive about 0.001. - From node B, I can send about 0.03, and receive about a 0.001.
- I create an invoice of 1000 sat from node B. - I attempt to pay the invoice from node A and receive "No path found". The log says: "electrum.lnutil.ConnStringFormatError: Don't know any addresses for node: [NODE_PUBLIC_KEY]".
I can pay node A from node B, but not the other way around. Isn't it odd?
It is. Are you certain that the channels are open? Do you have a link on 1ML where I can see the channels? Node B is CLN and node A is LND? Perhaps it is the common issue when having 2 nodes with different implementations. The routing algorithm differs and sometimes it fails. I am searching the web to find a relevant post and I will guide you to it.

With a transaction fee of $50, I presume the miner is part of the club.
Or perhaps Foxpup is the miner. Don't forget foxes dig mine a lot. Like this one for exampleEDIT: Let's not derail the conversation once again. Sorry Loyce, for continuously telling bad jokes on your thread.

Hi, the setup is as follows: 1) laptop with portable HDD, never connects to the internet 2) laptop2 with portable SSD, signs transactions, keeps an updated blockchain, normal internet usage on internal drive on a separate OS
If you need to run because there's a fire, thieves, or gov becomes north korea, you can put your 2 drives in a bag and gtfo, without worrying about no laptop.
If you need to wipe 100% your keys, you can do it because it's an HDD. SD cards or usb sticks or SSD drives would make you paranoid that there was a way to recover keys. Unlikely if you use FDE but still. Since you don't need to sync the blockchain on your HDD, it doesn't matter that it's slower, it's just to store keys and sign tx's, so an HDD is good to go, that is why im asking, what would be a good one to buy. Also, if you use Bitcoin Core as wallet, you need the actual file.
The signing must be done on the offline computer, not the online one, since signing requires private keys and therefore if you have the private keys on the online device, then essentially all your wallets are hot wallets. I would do the following if I wanted to maintain the 2 computers logic: 1. Online device - A small pc (NUC or Raspberry) with a portable SSD, that would act as a bitcoin node. All the data would be installed on the SSD so in case of fire I would take it and go away. In fact I could also take the small PC with me. But even if I didn't take it, no big deal, I guess. Note: Using an NUC, you can use internal NVME and then just take the whole PC and run. 2. Offline device - Cheap laptop with the cheapest internal disk. This would be used only for key generation and signing and it would be connected to the node on device (1). I would setup Linux and install Electrum on this device. I would make sure to fully encrypt the disk with a strong password that I would copy in 2 physical media stored in separate places. Of course, for any wallet that I generated I would keep the seed phrase in physical media too and anytime I created a wallet, I would erase the memory after backing it up, so If I needed to sign I would have to type the seed phrase again and then re-erase it. Imagine something like a temporary signer. In case of fire, there is nothing inside the laptop, and even if the stole it, they wouldn't be able to access it, because: Linux with full disk encryption. Final Note: Running is unnecessary. The only thing you really need is the backups of the seed phrases and to make it difficult for the thieves (or anyone you worry about) to read the disks if the computers are compromised.

Hello.
I don't understand from the post what kind of problem you face.
Is the funding transaction slow? Is the channel opening transaction slow?
Both these operations require an on-chain transaction so you must make sure the fee that is set is high enough.
Also take into consideration that in order for the channel to open, it requires 3 confirmations.
I am not aware of the services you have used, but I have tried LND and CLN and in both occasions it took approximately 1hr for the channels to open.

Software level airgap - you have turned off your WiFi in your OS.
Hardware level airgap - you have physically removed your WiFi card (or never had one to begin with).
I think both are very secure, but software airgap has 2 possible flaws: 1. software malware like the one you mentioned in the answers above. 2. it's just one click away from becoming "non-airgapped". I think this has also been mentioned somewhere above. In any case, yes, hardware level airgap is not so prone to errors.

I don't argue with you, hardware lever airgap is much safer without a doubt but my point was that software level airgap isn't very dangerous for average computer user who lives in average neighborhood. There are people who don't know how to disassemble Laptop.What if I am that person and live in a village in a big house, in masonry walls and I have password set on my Wi-Fi? So if I don't type Wi-Fi's password in computer, computer won't be able to log in. To be honest, I don't argue with you because your advice is the most correct one, I am just stating, I don't feel like software airgap is dangerous in some cases. Overall, I suggest everyone to follow your advice for better security.
I wouldn't call it dangerous, per se, but just less secure than a hardware airgap. As I've said above, a software airgap is still much more preferable to a standard hot wallet.
What is considered a software airgap? I don't understand how software could help being airgaped? Like a software that blocks WiFi or one that blocks Bluetooth?

Hi.
Perhaps I don't understand the question so I need to verify. What do you want to store on the external drives? In most cases, you can just run the wallet on the laptop and in case of an emergency you can use the seed backups. That's for the hot wallet.
In case of cold storage you can generate it on the air gapped laptop using electric and store the backups on physical media, produce the xpub so you can generate a view only wallet and then you can delete it from the air gapped laptop
Do you mean you want to run your own node (Bitcoin core most likely) so the Blockchain needs to be downloaded to the HDD?

Το θέμα με το να τρέχεις το Bitcoin είναι να το τρέχεις σε έναν υπολογιστή που μπορεί να το σηκώσει και με κάποια άνεση. Σε τελείως θεωρητικά πλαίσια ένα Raspberry pi μπορεί να το τρέξει, στην πράξη δεν έχει νόημα γιατί τα specs είναι τόσο χαμηλά που δεν θα μπορεί αν το τρέξει σωστά. Και επίσης με την έλλειψη τσιπ τα raspberry pi είναι δυσεύρετα και πολύ ακριβά ειδικά στην Ελλάδα. Άσε που τα εξαρτήματα στην τοπική αγορά είναι ανύπαρκτα.
Καλησπέρα αλάνι. Έχω RPi 4b με 8 GB ram και τρέχω πάνω του bitcoin core + electrs + sparrow terminal και θα βάλω και monero node σε νέο tutorial. Γενικά νομίζω παίζει άψογα το RPi για αυτή του δουλειά. Παλιά έτρεχα Umbrel πάνω σε ένα ολόιδιο RPi και έπαιζε φανταστικά! Συνολικά δεν είχα δώσει πάνω από 150 ευρώ για Pi 4, case, φορτιστή και 1 TB HDD. Από skroutz μπορείς να το βρεις με 70. Δεν τρέχει γρήγορα, αλλά για σπιτική χρήση είναι ό,τι πρέπει. (Σηκώνει και c-lightning) Επαυξάνω!

Hardware wallets are no longer safe since Ledger claim that they can extract your seed if they want with just an update and even if you didnt update your wallet they may do it without your permission in the moment you connect to internet
Hi. Hardware wallets are perfectly fine if used properly. Ledger wallets are not. But thankfully, they are not the only ones available out there.

I checked it out. It is absolutely essential to have the respective SeedSigner to Monero, but as far as I can see, it's under development. I wouldn't use it to store important amounts there. Instead, I would rather dedicate a spared laptop (which costs less than a RPi zero), airgap it, and install the officially supported Monero GUI wallet from getmonero.org.
Man, I totally agree with you and everyone who says that, but unfortunately I don't have an old laptop or pc or any device like that. But as far as the MoneroSigner is concerned, until it is properly released and tested I wouldn't use it either.

Ok, Electrum, Sparrow and Bitcoin Core are top notch. I really don't see any other option anywhere near them. I have opened this topic in the past, in case it helps, to compare Electrum with Sparrow.

I have been using this address for some years now, so i got some money from Si^D^^ recently but what about those satoshis which i got when i was not in that campaign ? I transferred some satoshi to some other wallets before the campaign too. So all those wallets become suspected Yes, if you have received coins to the same address, then it is obvious that you are the owner of the address. If you gave me the address A to send you money there and you also gave it to another user, then all that money is now blended together and if someone tracked my transactions, they would also see the other user's payments on that address. Having seen that, I strongly recommend using the swap method that I explained above.

The only thing I wish for, having had some difficult times lately, is to be healthy and full of energy.
May you all be blessed with health and positivity.
Merry Christmas!

I thought the same in 2017 I hardly knew about Bitcoin in 2017 60 sats/vB is definetely a lot in absolute terms, but for the current period it isn't that big. I mean, I had a payment I needed to make, so I combined 3 UTXOs setting the fee rate at 60 because I didn't know if I would have this chance again in the near future.

That sounds expensive if you don't need to consolidated funds any time soon.
My current personal strategy is not to jump off the deep end at price higher than 10 sats/vB, sure , everyone makes it on their own regarding the current situation with mempool.
But how do you both know that the fees will drop? I believe high fees are here to stay! Unfortunately. Yeah, it is expensive anyway... But I really don't think fees will drop.

Alternatively, if you don't know what you're doing, buy yourself a signing device like SeedSigner. It requires minimum technical knowledge to setup, and is completely airgapped.
SeedSigner is in fact one of the best projects out there. And unfortunately not a lot of people talk about it. People prefer to use Ledgers... I mean, what the ... Anyway, o_e_l_e_o recently told me about this: https://monerosigner.com/ which is the essentially a SeedSigner fork for monero. I just mention it because, you never know who could be interested.

Fees now have dropped to 80~ sats/Vbyte, if nothing much changes, in a few more hours you may get away with 40 sats transactions, there is a large wall at around and above 40 sat (almost a whole day's worth of transactions) so I think 40~ sats would be a good level to consolidate if you are rushing and don't want to wait, I think we would eventually in a few days get to 10-20 sats, but probably never again see 1-2 sats unless something major happens.
Thanks mikey. Personally I took the chance to consolidate some inputs and also make some pending payments at 63.5 sats/vB.

What OS did you run? Mine is downloading the monero blockchain now and the temp is currently 43.8 celcius. I don't remember exactly with Bitcoin but I can tell you for sure that it never went over 58-60 celcius.
But RAM is very important for this. So 8GB work much better than 4GB.
Raspbian. Mine was above 70 for most of the time, but again your cooling method makes a huge difference. Having the entire casing as a heatsink is undoubtedly better with what I've had on hand. RPi4s were notorious for overheating actually, might've been the issue with the earlier versions. RAM is important, but RPis are pretty expensive so I had to skimp on it back then. RAM shouldn't affect temperature anyways. To be honest I have created a node as a series of tutorials for Bitcointalk here. This node runs Raspbian Lite and to be honest the temperature went close to 65-67 degrees during the IBD. The other node that I have runs Start9 and the IBD went very smoothly and much faster than the other one's. I used to have Umbrel too and I don't remember any issues too. I just switched to Start9 because I loved its simplicity and the fact that it is much easier to customize.

I think I ran it with my RPi 4, 4GB. How were your temps looking during the synchronization? Mine was fairly hot throughout, granted that it was just a heatsink and not a fancy heat dispersing case.
Not to mention, it took weeks.
