The one that is most commonly recommended on these forums is Tails.
Got it, thanks a lot. Installed on an USB-Drive, opened it and found - Electrum. Wow. Looks good.


An airgapped device is not one which is currently disconnected from the internet, but rather one which will never connect to the internet again.
But how does this device interact with the Blockchain / Full-Node? Did you mean an (Android)Mobile without sim and without wlan?

don’t have hardware-wallets for the moment, but Your proposal seems interesting even for software-wallets. No one could physically steal / compromise data that don’t exist. But these liveOSes i know are read-only Linux Iso-images on CD / USB-Drive. That mean i use Internet with an outdated system, maybe with a lot of leaks.

Could it done with an ordinary Debian with an external USB3.0 hard-drive? It’s fast enough and maintainable. Plug-off and there is a nice harmless computer without any wallet-software. Disk encryption (without /boot) is also possible. And the wallet is not connected permanently to internet.

@Miau222
I have just noticed you repeated Elektrum in your post, it is Electrum. Be careful of fake sites. You can download the wallet from https://electrum.org and make sure you verify its signature.
You're right and i've edit my posts, even the Subject. Sorry please. And please can someone edit the Subject of other posts? No one should be confused about that and then loading a fake-version.


Exactly. But I am thinking Miau222 wants to create seperate wallet on the same wallet app, but if this is what he meant, like 2 passphrase for one seed phrase wallet, I have not seen a wallet like that before and not possible on Electrum.
This is what i meant. But to create separate wallets with the same seed don't make any sense to me.

So i'm ready to start now ...

Very nice lexicon. And good to hear from an experienced user about the Bitcoin fees.

Creating multiple wallets with 2 or 3 passphrases is a interesting feature for me. Can i do this in Electrum?
The passphrase/extra word is given during creating the wallet. When i open my wallet with the pin, then is there any way to open some hidden child-wallets? Maybe it’s a feature for new versions. Electrum with multiple wallets is welcome, a (wo)man with multiple personalities not.

[@Rath_]
The path to the wallet i found in a hidden folder: /home/miau/.electrum/wallets/
Only 2.7 kByte. Maybe have to put some coins in, then the file will be heavier.

But i hope the Lightning-support will increase in future versions. It will be necessary, if transactions cost 3...50$ (like some guys report) small amount will be useless.

@all
Thank you for your answers!

These are good advises, thanks. i will study them, even the link’s.
Normally the bank take care of this. But here the Person have the totally freedom about the amount but take care of all. I think the potentialities are much greater but the risk also. It is like a “coming of age”.

So every day i end my business with Elektrum Electrum, then i make an backup. And then i can restore everything if needed (File -> Save backup), even the lightning channels, right?

[@Rath_]
move your coins” and “non-chain transaction” is “Lighning”? Or did You mean “copying”?

You can safely recreate your wallet with your seed on some other device at any time, but you won't be able to access coins locked up in your channels.
Is it not possible to transfer the last PC-backup to mobile Elektrum Electrum App and restore and work there? (Same version of Elektrum Electrum)
7  Bitcoin / Electrum / Questions to Electrum on: January 11, 2022, 09:18:06 PM
After reading in some posts here i need some knowledge about your vocabulary. It’s sometimes like Martian.


I’ve read the word “seed / phrase” and “passphrase” and “extra words”and “pin” and “General-pin” and “key” in different context and it seam to me many newbies are a LITTLE BIT confused about that.

Charles-Tim said: But hope you did not include extra word (passphrase)?
So is it not an good advice to use extra words as an passphrase? It an extra security to the wallet, isn’t it?

Some people and shops using Lightning because it’s cheaper and faster. If i have to restore the wallet (maybe lost) with the seed, will everything be restored, even all Lightning-nodes and payments?

If i restore the wallet, can i safely change the seed/pin so that the wallet cannot be compromised from others, someone who found it?


So i want to study the basics before start here. Thanks a lot for your answers!

Ah, thank you very much. Of course an signature file must be much smaller then an gpg-key but has the same fingerprint. So i'm free to use the installer.
9  Bitcoin / Electrum / Problems with verification after downloading Electrum-4.1.5.tar.gz [solved] on: January 10, 2022, 11:12:23 PM
Hey there,

pls allow me to share an problem with the verification after downloading Electrum-4.1.5.tar.gz from the site:
https://electrum.org/#download

Then i downloading and import the file “ThomasV.asc” in gpg (sorry it’s in german):

$ gpg --import ThomasV.asc
gpg: Schlüssel 2BD5824B7F9470E6: Öffentlicher Schlüssel "Thomas Voegtlin (https://electrum.org) <thomasv@electrum.org>" importiert
gpg: Anzahl insgesamt bearbeiteter Schlüssel: 1
gpg:                              importiert: 1



After that i try to verify the archive:

$ gpg --verify ThomasV.asc Electrum-4.1.5.tar.gz                      
gpg: verify signatures failed: Unerwarteter Fehler



So i’ve looked what Thomas wrote on his website and have done this:

$ wget https://download.electrum.org/4.1.5/Electrum-4.1.5.tar.gz.ThomasV.asc
--2022-01-10 21:41:27--  https://download.electrum.org/4.1.5/Electrum-4.1.5.tar.gz.ThomasV.asc

2022-01-10 21:41:27 (10,1 MB/s) - »Electrum-4.1.5.tar.gz.ThomasV.asc« gespeichert [833/833]


Then i’ve been astonished about the small amount: 833 Byte. After that i tried to verify:

$ gpg --verify Electrum-4.1.5.tar.gz.ThomasV.asc Electrum-4.1.5.tar.gz
gpg: Signatur vom Mo 19 Jul 2021 20:22:29 CEST
gpg:                mittels RSA-Schlüssel 6694D8DE7BE8EE5631BED9502BD5824B7F9470E6
gpg: Korrekte Signatur von "Thomas Voegtlin (https://electrum.org) <thomasv@electrum.org>" [vollständig]
gpg:                     alias "ThomasV <thomasv1@gmx.de>" [vollständig]
gpg:                     alias "Thomas Voegtlin <thomasv1@gmx.de>" [vollständig]


So far so good. Then i tried to import the key. First i deleted the other one:

$ gpg -k
pub   rsa4096 2011-06-15 [SC]
     6694D8DE7BE8EE5631BED9502BD5824B7F9470E6

uid        [ unbekannt ] Thomas Voegtlin <thomasv1@gmx.de>
sub   rsa4096 2011-06-15 [E]

$ gpg --delete-keys 6694D8DE7BE8EE5631BED9502BD5824B7F9470E6

Diesen Schlüssel aus dem Schlüsselbund löschen? (j/N) j


And then import the small key:

$ gpg --import Electrum-4.1.5.tar.gz.ThomasV.asc  
gpg: Keine gültigen OpenPGP-Daten gefunden.     [no valid OpenPGP-Data found]
gpg: Anzahl insgesamt bearbeiteter Schlüssel: 0


Wow, what’s happened there? I’ve extract the archive but feel not free to install. Maybe someone can explain?


Thank you in advance
