just restore it from your electrum seed (if you have it), open your electrum wallet (in desktop) > file > new/restore > click wallet with two-factor authentication > next > click already have a seed > click disable when asking 2fa.

Correct answer.


You should already have backup of your electrum on paper or in digital form, and that can be private key or backup phrase.

I don't think you can set up TrustedCoin 2fa with an imported private key.  It must have been a seed-phrase HD wallet, and I doubt that he backed up individual, funded private keys from and HD wallet.


The electrum wallet 2 factor authenticator type make use 2-of-3 multisig wallet for signing, one signing from you wallet, and the other signing from TrustedCoin. But if you lost your 2fa app and you do not have the backup code, you can still be able to make transactions on your electrum wallet because you are in control of two private keys, all you need to do is to restore you wallet. Use the below guide to restore your wallet.

Restoring your seed from two factor authentication Electrum wallet

Even if TrustedCoin is compromised or taken offline, your coins are secure as long as you still have the seed of your wallet. Your seed contains two master private keys in a 2-of-3 security scheme. In addition, the third master public key can be derived from your seed, ensuring that your wallet addresses can be restored. In order to restore your wallet from seed, select “wallet with two factor authentication”, as this tells Electrum to use this special variety of seed for restoring your wallet.

Your post contradicts the instructions you quoted.  I don't know what you mean by "backup code" but I'm assuming you're talking about the seed phrase.  In order to restore the wallet you need the seed phrase, there's no way to do so otherwise.  And I also don't know what you're talking about when you say "in control of two private keys," but again I'm going to assume you mean seed phrases, which is wrong.  There's only one seed phrase that's needed to make or restore a 2fa wallet.  TrustedCoin doesn't provide a second seed phrase, that would defeat the purpose of having them issue the second signature in the first place.


@OP, I hope you have the seed phrase that was created when you set up your wallet, that's the only way you'll be able to restore your coins.  I also recommend that you don't use TrustedCoin 2fa.  If you're concerned about the security of your coins you should buy a hardware wallet.  The fees charged by TrustedCoin will more than pay for a hardware wallet, which is much more secure, and leaves you and only you in control of your coins.


2062  Bitcoin / Electrum / Re: WALLET ADDRESS, IS IT PERMANENT? on: June 20, 2021, 08:43:46 PM
I think they should hide this behind a check box in the options menu, just like they do for the advanced preview screen.

That would be an improvement.  I agree that the invoice expiration feature is about as useful as tits on a boar, and doesn't really add any value to on-chain transactions.  Anything communicated by that feature could easily be addressed in whatever agreement arrived at by the individuals initiating the exchange.

IIRC the feature showed up in the gui around the time the dev team was implementing Lightning features, which have legitimate uses for request expiration.  Maybe it was just as easy to add the subscripts to on-chain requests, and here we are.

In actuality I find the whole Receive tab to somewhat useless.  I just use the Addresses tab to keep track of my used, labeled, and unused addresses.
2063  Bitcoin / Electrum / Re: How can I create an OP_RETURN TX with the Electrum console? on: June 20, 2021, 08:22:53 PM
Outputs are scripts, addresses are scripts as well.

Thanks for the clarification, makes perfect sense.  Nevertheless, I don't think that the blockchain should be used as someone's personal notepad.  Seems like a dick-move...

Or perhaps a bit more accurately, a cunt-move.
2064  Bitcoin / Electrum / Re: Electrum 4.1.3 released on: June 20, 2021, 08:11:36 PM
Recently the Electrum team started providing 2 sets of signatures from 2 of their developers, I suppose to make things safer and more decentralized.

I suspect you're correct.  That would make things more decentralized, and it's a good plan going forward to keep things transparent.  If (god forbid) anything happened to ThomasV and suddenly the team had to use someone else's key to sign releases it would raise a lot of questions.  Especially if that someone (like Ghost43/SomberNight) was an anonymous figure.

Anyway, I browed to the Electrum download page today and noticed the following, for some reason the MacOS releases are still signed only by ThomasV:



I also noticed that two sets of signatures are available now.  I don't believe that was the case when I downloaded version 4.1.2.

Going to another country might not be necessary.  Check for communities in your country and state that operate their own power infrastructure.  

A few rural counties in my home state have their own hydroelectric system that they use to generate power for their community at drastically discounted rates in comparison to the rest of the state.  They often sell surplus power to the big power companies and use that income to amortize the maintenance and operation costs, thus keeping the power rates affordable for the local communities.

There's no rule stating you can't have multiple accounts.  You can have as many as you want, as long as you follow the rules. If someone is proven to have multiple accounts that are being used to mulit-post or bump threads then the rules are enforced as if it was only one account doing that. If one account gets banned for breaking the forum rules, then all remaining accounts are banned as well.  When an account is banned the biological entity behind those accounts is banned.
2067  Bitcoin / Development & Technical Discussion / Re: How can I start Bitcoin Core on Windows without a GUI? on: June 19, 2021, 11:37:55 PM
I've never tried this, but you might be able to use the "Task Scheduler" to set up bitcoind to run as a background service.  The gui isn't very taxing on system resources, and if you setup the gui to minimize itself to the tray on closing, it's essentially the same thing.

The only reason I can imagine someone wanting to do this is for security on a shared computer, ie, you don't want others who are using the PC to know that bitcoin is running on that machine.  If you are doing so just to bolster the network with another node, you can disable wallet rpc functions in the bitcoin.conf file.

I verified your signature, and I've confirmed that it was made with the key belonging to that fingerprint.

Edited the fingerprint to match the format.

You're formatting is still fubar, there are two spaces between these two segments: "24F7  01BA"

It really doesn't matter though, I wouldn't edit your post again.  Anyone who wants to verify a message signed by you will be able to see that the fingerprint is accurate.

Thanks for the link.  Are the releases also signed by ThomasV as has been the case in the past?  Sorry, I'm traveling for business, and don't have the opportunity or time to check.

It may worth also mentioning that SomberNight has started using a new GPG key:

2071  Bitcoin / Electrum / Re: How can I create an OP_RETURN TX with the Electrum console? on: June 18, 2021, 07:58:34 PM
The two commands expects an address and does not parse scripts (OP_return)[1], while the GUI does[2].
Could you not call the same method as is called through the GUI? I have seen other methods that are not GUI commands be called this way and I'm not familiar with python.

That was my initial thought.  I would assume that gui functions are a set of predefined commands that can by manually configured in the console or or cli.  As for requiring an address, wouldn't OP_RETURN require one as well?  I'll admit I've never used it (see below,) but I was under the impression that it required a fee, and some bitcoin to burn.


I hope you know that bitcoin blockchain is not a message storage database.

Yeah, I really don't want to upgrade all my node hard drives any sooner than I have to.  Use ETH for that kind of stupid shit.  It's blockchain is a clusterfuck already.
2072  Bitcoin / Electrum / Re: Can I use a 12 word seed extension and store it separately? on: June 16, 2021, 02:49:34 AM
My main motivation behind this post is to have my backup in two pieces to protect against a physical intrusion. A 24 word seed with higher entropy has no benefit over a 12 word seed if the physical backup is stolen. If I break the 24 word seed with 256 bits into two 12 word parts, can I safely store them in two separate locations like I can with the seed extension?

Of course you can store your extension separately from your seed, regardless of it's length or the origin of the words.  As Leo mentioned above, it's actually recommended.  If you want to, you can generate two 24-word seeds and store them separately.  
2073  Bitcoin / Electrum / Re: Can I use a 12 word seed extension and store it separately? on: June 16, 2021, 02:27:42 AM
@xmready, I've used a 12-word seed as an extension in the past.  When I was a younger bitcoiner I thought that would double my entropy, but I've since learned that it does not.  Take a look at hosseinimr93's post above, he is showing you how to generate an honest-to-goodness 24-word seed with double the entropy of a standard 12-word seed.  I also advise against using the same pool of words (i.e. Bip39 word list) for your extension, just to add an extra level of security.

in Austria there is a 3 G rule, tested, recovered or vaccinated

That's awesome news.  It's good to see some folks apply common sense, it's been far too uncommon the last couple of years.  I've been thinking about booking travel for the Thai or the Malaysian GP, but decided to put it off until next year just in case restrictions don't get lifted.  The dates for American and Argentine races are still pending.  

It's odd the American GP hasn't been scheduled yet.  It's held at the Circuit of the Americas in Texas, and if I'm not mistaken Texas has lifted all restrictions.


For the next GP in Germany, the difference of 14 points from Zarco seems that Quartararo must appear without errors so that he continues to lead the standings temporary.

There's still a lot of the season left to go, only a third of the races have been run so far.  Anything can happen, but I wouldn't mind seeing Quartararo, Zarco, Miller duke it out all season.
2075  Alternate cryptocurrencies / Altcoin Discussion / Re: Will The Sorrow of BTC Be The Pleasure of Altcoins? on: June 14, 2021, 03:22:55 AM
This silliness was debunked hundreds of years ago:

Quote from: Shakespeare
But soft! What light through yonder window breaks?
It is the blockchain, and bitcoin to the moon.
Arise, fair bitcoin, and kill the envious alts,
Who are already sick and pale with grief,
That thou, their forbearer, art far more fair than they.


All kidding aside, most alts that have been around for a while do have a use case.  Litecoin, is often more affordable to send, and lighter on equipment for hosting a node and mining; Monero has the ability to obfuscate transactions; ETH is good for smart contracts, and therefor tokens.

They all have their various issues whether with security, expensive fees, volatility, regulation, availability, or adoption.  Bitcoin has proven to be secure, resilient, and adaptable.  Segwit, and most recently TapRoot have contributed in keeping fees lower.

The next biggest blockchain, ETH has a host of issues, in my opinion.

Nayib Bukele is the real deal.  The guy has done an amazing job cleaning up street gangs, and locking up extortionists.  But he's not short-sighted either, he knows he needs to do something about El Salvador's economy before something gets done about the US it's immigration problem.  There was a time when El Salvador's largest employers were drug cartels, and nearly 20% of their GDP was remittance.

Promoting his country's natural resources for something that's already being talked about in the news.  This is a great idea and his timing is impeccable.

Why would you use both accounts on Binance when everything can be tracked and connected back to you, it doesn't really matter if you are useing vpn or not.

This is the first thing that I thought when I read the OP.  The OP must have sent his KYC docs to the .com site, and if he were to trigger an AML investigations they would know where to find him, vpn or not.

@OP, don't fuck around with your funds trying to do something the site isn't meant for.  If you're suspicious about the source of some of your funds, send them through a mixer before sending them to an exchange that has your KYC.  Duh!  VPN, .com, .us, non of that matters, they have your KYC!!

There are some highly trusted, reputable mixers out there, and at least one that I know of can be used for free.

Something is very wrong if we see young people having strokes like this.

I agree, there's something weird going on.  I would hear about this type of thing happening in the early 90s when there was a lot doping going on with experimental drugs.  I doubt that's the issue here, but a young, healthy, athletics man suffering cardiac arrest without contributory factors is very rare.

This on the heals of the CDC releasing a study suggesting that the Covid vaccine is causing myocarditis in young men, primarily ages 18-30.


Thankfully the news was broke by UEFA very quickly that he is fine, and there is nothing to worry about, he will be in hospital for a while and rest and he will get back, there is a chance he could play ball in regular season again if he wants to as well.

Can you imagine?  What a scary episode.  I hope they figure out what caused his heart to stop, so he can play again.  If they don't know or they find it's something that can't be cured his career might be over.  Let's hope for the best.


That was some match. 3-2 and it did reflect Ukraine's skill at the front, and a lot of luck on the Dutch side, but really they were helped on by poor goalkeeping from Ukraine I'd say -- now I know why the Dutch aren't favourites ha. Their keeper wasn't really tested either I'd say but he does seem a weak spot as well. So far, no upsets. My first freebet locked in with this win. Til tomorrow;)

That was a good match for the last 25 minutes, lol.  It looked like the Dutch had it in the bag, and it was kind of boring at first.  Very exciting second half though.

2080  Economy / Reputation / Re: Abuse of DT by odolvlobo? on: June 12, 2021, 12:58:05 AM
Agree but I don't think it deserves a negative and if a designer doesn't mention the software they use, doesn't mean they are scammers.

I never said he was a scammer, but it's obvious to any one who's been around for a while that he's not being completely honest.  I also said that I think the red-tag is harsh.  In my opinion a neutral tag would suffice, but that's my opinion not odolvlobo's.  The trust system is meant to be decentralized, and this is why.  Some of us find some things more troubling than others.  If other DT members find his use of the trust system to be abusive, then odolvlobo's tenure on DT2 is likely to be short-lived.
