In python you can name the arguments to make it clearer:

Code:
make_seed(nbits=128, seed_type="standard")
62  Bitcoin / Electrum / Re: How To solved Electrum Signature verifiyed on macOS Monterey version 12.6.2 on: January 12, 2023, 08:12:35 AM
you're supposed to verify electrum before you run it. as for the issue of not connecting to a server the screenshot you posted shows electrum has connected to a server successfully. a green circle icon in the bottom right tells you that the connection was successful.
63  Bitcoin / Electrum / Re: Canceling a transaction on: December 01, 2022, 06:15:05 PM
You can do that as long as your transaction is unconfirmed. Canceling = replacing your old transaction with a new one that sends the funds back to your address.

Confirmed by the system or by the client?
And how long does it take to confirm?
Thank you in advance!

A new block is mined on average once every 10 minutes so that's how long it takes for a transaction to be confirmed
64  Bitcoin / Electrum / Re: Is bip32 safe with electrum? on: November 25, 2022, 09:17:02 PM
bip39 seeds don't include the derivation path and the script type so they are not idiot proof. the onus is on the user to figure out the correct derivation path and the script type. electrum seeds include a version number and electrum can use that to figure out the correct derivation path and script type automatically.
65  Bitcoin / Electrum / Re: Electrum Address keeps repeating on: November 24, 2022, 09:37:29 PM
you should post a bug report on github:

When people say a bad OS can fuck up /dev/urandom what do they mean by that?

idk

Quote
I think i am being ultra paranoid here.
So if i want to generate a strong random seed it doesn't depend on say hardware?
I mean if i have old PC will it generate less random seed compared to new gen PC?
If i use electrum on linux vs windows which is more better to generate random seed?


it doesn't depend on hardware. either windows, linux, android or OSx is fine. electrum uses a cryptographically secure random number generator on all OS.

Please read http://stackoverflow.com/questions/5480131/will-python-systemrandom-os-urandom-always-have-enough-entropy-for-good-crypto

/dev/urandom can indeed run out of entropy if it is called repeatedly.
{snip}



Sorry for bumping the old thread.
So does that mean say i repeatedly generate seeds say 100 seeds one after the other before finally deciding the choose the seed for my wallet. Does that make the seed less secure?

no it doesn't. /dev/urandom can generate unlimited cryptographically secure random numbers. it doesn't run out.

It doesn't run out that's true.
But there's something weird definitely.
I tried it. I created seeds in electrum wizard. After 30,40 seeds the wallet closed. (may be randomness was weakening? ) . I again open and tried. Same happened again.
Also the post i quoted. Electrum developer also confirmed /dev/urandom can run out of entropy if it is called repeatedly.
Found similar concern here as well - https://bitcoin.stackexchange.com/questions/62871/does-my-electrum-wallet-become-less-secure-if-i-keep-generating-seeds-until-i-se

andrew chow's response there is the correct answer to that question. andrew is a bitcoin core contributor and knows what he's talking about:

https://bitcoin.stackexchange.com/a/62894/5273

also  this answer to the stackoverflow question is the correct one:

https://stackoverflow.com/a/5498100

/dev/urandom only needs to be seeded with a small amount of entropy. this happens at bootup. after that its pseudo random number generator can generator unlimited amount of random numbers.
68  Bitcoin / Electrum / Re: is it Safe using console to generate seed? on: November 15, 2022, 02:58:46 PM
only commands that you enter are recorded not the output of those commands. also it'll generate a 12 word seed by default unless you pass in the nbits argument.

70  Bitcoin / Electrum / Re: Wrong tx number and balance for imported address on: November 14, 2022, 02:08:37 PM
you could file a bug report on github issues. they will likely ask for the debug log.

https://github.com/spesmilo/electrum/issues
71  Bitcoin / Electrum / Re: Wrong tx number and balance for imported address on: November 13, 2022, 03:16:44 PM
Yeah that address has too many transactions. i created a watch only wallet with that address and electrum is struggling to synchronize with a server. you will need to use bitcoin core to watch this address.
72  Bitcoin / Electrum / Re: Electrum 4.3.2 - Two-factor authentication that has never been set up (no seed) on: November 13, 2022, 01:12:39 PM
if you have google authenticator on your phone look for an entry title trustedcoin. that's the 2fa code you need.

if you can't find anything like that your only option is to contact trusted coin and ask them to reset the 2fa for you. they say on their site that they won't help but people have gotten them to help in the past:

Thank you. I hadn't been on this forum for the past couple of years, but I remember that in the past you had given me some very valuable information. It was the LN instructor I mentioned that suggested to use only one node and recommended a couple of them in particular. His point was that that some nodes in the crowd might be a bit dodgy, and that using one node only is slightly better in terms of anonimity. I guess I'll follow your advice, but I'd like to hear your comments, if any, on his take.

P.S. I hope this post gets accepted - my previous reply got me a warning from a moderator which I wasn't able to understand for lack of familiarity with the terminology.

Electrum relies on servers for blockchain data but it does not trust them. They are run by random volunteers and cannot be trusted. Getting data from multiple servers and cross checking it is better than relying on any one server. The exception to this rule is if you are running your own server in which case you have a copy of the blockchain locally and don't need to trust anyone else.

sadly local cryptos is shutting down. i hope pakistani traders migrate to hodlhodl.com.


Why is it closed? It will be easier for us to understand if he explains fully. Don't bother me with this little question of mine. If I don't know about something I will learn from you. You will teach us. Don't get mad at us anymore while you're there. Because we don't know everything, we try to learn from you. thanks brother.



They have cited a few reasons on their blog:

https://blog.localcryptos.com/after-5-years-localcryptos-is-saying-goodbye/

personal health of the staff is cited as one reason.

Welcome  Abdus samad bhai. Good to see OP posting here.

Mera khayal ma to binance bhe eik acha option hy agr ap na trading krne hy aur P2P trading is best way to convert your crypto to Pakistan rupee , binance p2p trading ma zero fee hy.

Ma na hodlhodl.com kabhi try nhi ke. Can you share your thoughts on what it is?



hodlhodl is a virtual meeting place like localbitcoins and localcryptos. People can post ads to buy and sell bitcoin and then they can trade via the platform.

Most importantly it does not require kyc measures like uploading id. I find automated ID verification systems buggy and hard to satisfy.

Connecting to just one server reduces your security somewhat. I would be cautious about doing this.
77  Bitcoin / Electrum / Re: Cannot restore BTC addresses on: October 14, 2022, 12:44:56 PM
The other addresses might be in different derivation path if your addresses are legacy I would like to suggest use a tool called xPub analyzer to find those missing addresses and to lead you to the correct derivation path.

Here's the tool https://blockpath.com/wallets/local/101?action=appxpub

Export the master public key from your Electrum wallet and then paste it there then scan.
It would only show used addresses with balances including the right derivation path.

Electrum wouldn't hand out addresses that are not a part of the wallet. It's not a bip39 wallet.



What colour circle icon do you see in the bottom right? If it's not green try changing servers:

78  Bitcoin / Electrum / Re: Electrum Multisig Configuration fails - public general key false on: October 10, 2022, 04:12:12 PM
Electrum works with hardware wallets and has a mac osx version too.

Actually I run the Electrum Mac osx Version. So I add two Ledgers to the Electrum multi sig wallet. Understood. Is there any compatible iOS App, this would come in handy?

Again, your help is highly appreciated!

No there isn't. Electrum doesn't have an iOS version. Only android.

You can't mix and match wallet software like that. If you want to create a multisig setup all persons/devices have to be using electrum software.
