2021  Bitcoin / Electrum / Re: Sent to address while sychronizing on: February 08, 2016, 07:27:11 AM
Go to addresses tab. Open the "receiving" tree and then the "Used" tree underneath that. See if your address is under "Used".

If it isn't there then tell us if you were viewing some other wallet ? If you were viewing some other wallet then the address may be from that wallet.

If the address is under "Used" then you need to switch to a different electrum server by clicking on the red/green orb icon on the bottom right. This should update your balance.
2022  Bitcoin / Electrum / Re: Is the recovery key one factor access to 2FA or multisig? on: February 03, 2016, 07:51:09 PM
you can use the seed to recover your wallet .

Of course it's good to be able to recover without trustedcoin, but that's the point of 2-of-3 (compared to 2-of-2), and giving another party sole access to the third recovery signature.

Requiring both your private keys be in one place, as Electrum advises, seems to render multisig useless...

Right?


There are two types of multisig wallets in electrum:

A) 2fa with trusted coin
B) multisig. 2 of 2 or 2 of 3. no third party like trustedcoin is involved with this wallet type.

In the case of the type A the wallet mnemonic is indeed displayed at the time of wallet creation but it is not saved to disk. You are advised to start the wallet creation on an offline system and then move the wallet file to an online one to complete the wallet creation.

In the case of B if you use multiple devices you never have all the private keys on one system. I recommend B.

2023  Other / MultiBit / Re: treat me as a newbie for this, idk but, question about HD and the UI on: January 22, 2016, 02:34:25 PM
since HD rotates addresses, looks like this makes it had to maintain a single public address/vanity address?

You can continue to use an address forever if you want to. Addresses don't expire and all addresses derived from your seed can be used to receive payments. It's just bad for privacy and security to reuse addresses but if your not too bothered about that then by all means continue doing it. Better that you switch to HD than hold out because of this one thing.

Vanity addresses are not supported in Multibit HD AFAIK. Generally speaking you should avoid handling private keys directly. You have to let go of those old ways.
2024  Bitcoin / Electrum / Re: Electrum is saying "Server is lagging by 817 blocks". What does that mean? on: January 22, 2016, 02:25:25 PM
Click on the round red/green icon in the bottom right of the window to switch servers.
2025  Bitcoin / Electrum / Re: Difference between sweeping private keys and simply sending btc? on: January 22, 2016, 02:20:16 PM
So I want to send coins from my online wallet to my cold storage wallet.

Should I just send it to the address of my cold storage wallet? Or sweep? What exactly is the difference?

I know sweeping moves the whole balance. But other than that, is it exactly the same?

Thanks

Sweeping is used when you have a private key of a paper wallet and you want to send the bitcoins there to your electrum wallet. Otherwise you just send the bitcoins to a receiving address in the target wallet.

on github release notes the latest version is 2.6 but on the website there is one version older for downloading.
why is that?

Probably because the new version is still under development and testing and isn't stable enough for general release.
2027  Bitcoin / Electrum / Re: Multiple Bip32 accounts/wallets in the GUI or comamnd line on: November 02, 2015, 02:05:45 PM
Only one account is supported. Initially they planned to support multiple accounts but dropped the idea because it was deemed too complicated for most users. After seeing the sort of questions that get asked on this forum I agree with them.

Did you check both change and receive account addresses?

2030  Bitcoin / Electrum / Re: Need help with electrum wallet on: October 16, 2015, 09:52:46 PM
Electrum supports multiple wallets but you can open only one at a time. Use file > new/restore to create a new wallet and file > open to open a wallet.

If you want to create a shortcut that opens a particular wallet use the -w switch

electrum -w C:\\path\to\wallet.file

Location of wallet files:

2031  Bitcoin / Electrum / Re: Sent Money to a change address on: October 16, 2015, 09:51:31 PM
Hi guys,
I sent some money through Coin Loft to an Electrum change address by mistake.
Will I receive them in that wallet? Will my electrum wallet update that wallet?
Thanks guys.


Yes
2032  Bitcoin / Electrum / Re: Lost bitcoin on electrum wallet on: October 16, 2015, 09:50:09 PM
Electrum hands out a different address each time you ask it to on the 'receive' tab. So it's natural that the address there will change. I suggest looking on the 'addresses' tab to see if the address you sent bitcoin to is listed there. That tab lists all the addresses in your wallet. Be sure to look under 'used' as well on that tab.
2033  Bitcoin / Bitcoin Technical Support / Re: Blockchain Download on: October 10, 2015, 12:50:10 PM
That sound borderline illegal. It's open source, if you sell it for profit you're breaking the license. Its also available for free, downloadable for free and the bootstrapped downloadable for free, all under the same open source license.

This is bullshit. You can sell the blockchain because it is public database and there is no license attached to it. You can also sell most bitcoin wallet software including bitcoin core because they are released under the GPL and the GPL allows you to sell software. That's how redhat became a billion dollar company.

Edit: actually bitcoin core is released under mit license which is even more permissive:

2034  Bitcoin / Electrum / Re: Electrum Kali linux on: October 10, 2015, 12:44:59 PM
Just another question if you don't mind , how safe is the Electrum wallet that comes with tails ? and there is something that I can't seem to understand really ... which is Live using USB if I use the wallet which is by default on tails then reboot my PC and run the USB once again , will I find the bitcoins gone (if I don't save the seed) ? which means Live USB dosen't save anything ? so whats the point

It is for people who believe their computer might be:

Quote
I'am guessting *paranoid*  that my PC is infected or something

So they do their business using tails instead of the OS installed on their computer hard drive.

What do you not understand about the following sentence:

Quote
Tails is designed to leave no trace on the computer you're using unless you ask it explicitly.

Perhaps a brief history of linux live CDs will explain things to you. Linux live CDs were first created in order to make it easier for people new to linux to try it out without changing anything on their computers. So you downloaded and burned this CD and then booted off it and it allowed you to play with Linux for a while.

Tails does all of the above plus it allows you to use Tor and it is designed for activist people who want a secure environment that they can get just by booting off this DVD/USB drive. They don't want governments tracking them. They don't want to worry about the software already installed on the PC hard drive i.e. they will be using arbitrary public PCs. Stuff like that.

shorena 0.0002 is a bit too high. I suggest starting with 0.00005 like the article on bitcoin.org suggests and then increasing it from there if it's not enough.
2036  Bitcoin / Electrum / Re: Lost my password & cant restor on: October 08, 2015, 12:24:21 PM
When restoring you need to select the type of wallet. 2fa wallet in your case.
2037  Bitcoin / Electrum / Re: Electrum + Keylogger + TrustedCoin on: October 08, 2015, 12:22:44 PM
If your computer has malware when you create your electrum wallet then its possible the malware will just steal your seed. But if it doesn't have malware at the time of wallet creation then you are definitely protected with a 2FA wallet from future malware infections. The 25 word seed is not written to the wallet file so any future malware infection will not be able to spend your bitcoin all by itself. Any transaction will have to be signed by trusted coin and they require you enter the 2FA code first and of course in the process you review the transaction.

I have another question since you are here Grin what if I create my wallet offline ? I mean if I (by order) download the Electrum wallet , turn off modem , install it , setup the wallet , write down the seed and whatever and then boot the modem once again ?
But I remmeber that Electrum connect to servers not sure if I can get the seed without having internet connections or not ?

Any malware will just wait until you go online before it communicates the seed to the malware's author so no point in disconnecting from the net like that.

You can do cold storage with electrum on a permanently offline computer together with a separate computer that goes online:

http://docs.electrum.org/en/latest/coldstorage.html

Apart from that if you need a "sterile" environment you can boot of a linux live CD and use that to create an electrum wallet.

2038  Bitcoin / Electrum / Re: Exporting private keys from multisig wallet? on: October 08, 2015, 12:19:17 PM
The order of the keys on coinbin matters. Try a different order and you'll get a different multisig address.
2039  Bitcoin / Bitcoin Technical Support / Re: Problem on Ubuntu on: October 08, 2015, 12:13:42 PM
If you can't install from source just download the binaries from bitcoin.org. They work out of the box. Just extract the tarball and run.

See the part about transaction flooding:

https://bitcoin.org/en/release/v0.11.0

On reddit someone set minrelaytxfee to 0.0001 (double what is suggested above) and his node is using very little RAM.
