hi Abdussamad!
If I see balance, etc..... at online wallet, So I have to backup the appdata of online electrum?
I ask this because if i try to restore my seed just from offline wallet there is no funds, no money, any tip about it?
thanks in advance n' best regards!
No you don't have to backup the online wallet. The seed is all you need to restore your wallet. But to see the transactions and balance you need to be online and that is what the watch only wallet is for. When you say you restore from seed are you doing that on the online system or the offline system? If you are doing it on the offline system you won't see the balance or transactions. But you will see the same addresses as before. Are the addresses the same? IMO you might want to shelve this plan of using offline wallets for now. It is not something that newbies should be doing. Use online electrum for now and when you become familiar with it you can go for an offline setup. Otherwise the risk is that you make a mistake and loose your coins. |

Using the deseed command you can use a deseeded version of the wallet file to move it to the online computer, make transaction and then bring it back to the offline machine and seed it again.
Thank you for your answer. I couldn't find any documentation on this procedure, so I would ask you to clarify it please. So in the bash console of the offline computer I type $ electrum -o -w wallet1 deseed Then take the deseeded wallet file (wallet1) and copy it to the online computer, from the online electrum open the wallet1 file and make a transaction, close electrum. Then take the wallet1 file and copy it back to the offline computer, open it in electrum... and how do I reseed it ? Please correct me if I'm wrong, I'm trying to figure this stuff out but can't since there is no documentation. Thanks in advance. This isn't how it is done. When you run the deseed command it creates a new watch only copy of the wallet called wallet1.seedless. You copy that to the online computer and create a transaction. Then you save the TRANSACTION for signing on the offline computer. Then you carry the signed transaction to the online system and broadcast it. edit: Looks like I completely missed the point. You want to see the transaction on the offline system. The only way to do that is to bring it online. I think that's harmless unless you are using windows. A mostly offline wallet is not bad. You have to bring it online to update the OS anyway. |

Hi guys, I'm brand new (here), so, sorry if its a dumb question
using portable version in offline machine windows
using normal version in online machine windows
version 1.9.6
about de master key;
I go to the offline electrum menu> wallet> Master public key
copy the code
put the code in the field of start screen of the electrum online, so electrum create a wallet watching only
is that steps right?
Yes. another question;
How can I see my funds, balance and receive my bitcoins at electrum offline wallet? all my funds is at online, I need help with this, I read 6 pages already/gooogle and nothing hhuhaauahuahau
You can see the transactions and balance on the online system. To receive funds just copy an address from the watch only wallet on the online system and send it to whoever needs to pay you. Bitcoin transactions are not stored in wallets. They are stored in the blockchain. The wallet just stores the private keys necessary for spending the coins. In your case it is the offline wallet that has the private keys. You will only ever need to use the offline wallet when spending the coins not when receiving them. |

Long story short, Don't use propriatary garbage.
Use TrueCrypt or another open source encryption software instead.
The algo in question *is* open source. The problem is not open source or closed source. It is that the NSA has the best minds in crypto and no one else comes close. I wouldn't be surprised to learn that even bitcoin is an NSA invention. It's right up their alley. |

Some options:
bitaddress.org has some tools to change the format
blockchain.info import
you may use the converter provided at brainwallet.org
The address for a compressed key is different from that of an uncompressed key. So you have to import the compressed key or you won't be able to access your coins. |

What?! Are you talking about gox or stamp? 'Stamp takes 2-3 days at most.
How many times have you verified at Bitstamp to be able to make such a claim? I have verified 3 times with Bitstamp, it can take much longer. Last verification took 7 working days, that's a life time in Bitcoin. Why 3 times? There are 3 of you? |

I am trying to download multibit.org but its need Java as I try to download Java its not working on my computer again and again error and ask for re download I have Windows XP any suggestion for this
You can also try electrum. No need to muck about with java and you can restore your entire wallet from a single seed so backups are easy. I know you've had problems remembering passwords in the past and this will help you avoid losses if you forget your password. |

bah! its been like 18 business days for me.. still nothing.. over it

Those are compressed keys and you can import them as is using Electrum 1.9 or higher. You can't use them at all with older versions of electrum.

Accounts can help with this stuff, saves having multiple wallets for each coin if you really want to handle your accounting on that level: https://en.bitcoin.it/wiki/Accounts_explainedUsing accounts probably makes auditing a bit easier (e.g. you can audit the accounts without needing the database server which maintains website accounts) Accounts are a total joke. See The sendfrom method sends coins and debits the specified account. It does **not** change Bitcoin's algorithm for selecting which coins in the wallet are sent-- you should think of the coins in the wallet as being mixed together when they are received. There is no way to ask Bitcoin to "create a payment transaction using the coins received from these previously received transactions" without using the raw transactions API(which is not part of the account system.)
What does the above mean in practice? It means you can have an account with a negative balance! There is no isolation of the different accounts at all! |

(QT client, Multibit, Electrum, etc...)
These are different wallets with different mechanisms for generating addresses. With deterministic wallets like armory and electrum all past, present and FUTURE addresses are derived from a single seed. If an old backup is stolen they can grab all the coins including ones sent to existing and new addresses in the future. With QT it has 100 unused addresses by default in its pool and coins sent to any of those hundred as well as other used addresses can be stolen. Multibit also creates new addresses non-deterministically but I don't know it well enough to help you. |

I install the bitcoin client on every computer I use (except for my work machines, which don't belong to me), and routinely transfer funds between them. That way, I distribute my risk around multiple points of failure, so I can never lose my BTC. And I always backup the wallets on each machine to both an external storage device and cloud storage, so if one or more machines die for any reason, I can restore the wallet to a different client. Of course, all wallets are encrypted, so if any copy is stolen, the thief will find it worthless.
Are they all encrypted with the same password  ? |

Is dropbox considered a good option, or easily hackable? Let's say that the wallet is encrypted (talking about export feature in bitcoin-qt).
If the wallet is encrypted with a *strong* password, it can be stored anywhere. If its got a weak password, it shouldn't even be on your PC. No. Preventing potential attackers from getting access to the encrypted wallet file is a good thing. It is the main reason desktop wallets are recommended over something like blockchain.info my wallet - the attacker does not have access to the desktop wallet file and therefore cannot attempt to brute force it. If you want to backup your wallet buy a USB flash drive and use that. Or burn a DVD/CD. Don't put it in the cloud. |

You don't have to mess about with the json wallet file. Just type the following in the electrum gui console:
wallet.storage.put( 'gap_limit', 100)
The above command sets it to a 100 but you can, of course, use any number you like. Remember to restart electrum after you do the above!
Yes but I want to get rid of this red color. Then do what I said and increase the gap limit and restart electrum. |

However, I did find that if your add a 'gap_limit': 10 at top level in the wallet file then it does behave correctly and respect new addresses. ie. red addresses become normal.
Doesn't work for me. Where exactly do you have to place it? I placed it immediately before the seed version. eg. 'imported_keys': {}, 'seed_version': 6} becomes, 'imported_keys': {}, 'gap_limit': 10, 'seed_version': 6} You don't have to mess about with the json wallet file. Just type the following in the electrum gui console: wallet.storage.put( 'gap_limit', 100) The above command sets it to a 100 but you can, of course, use any number you like. Remember to restart electrum after you do the above! |

The "deseed" command still gives the message: >> deseed
Traceback (most recent call last):
NameError: name 'deseed' is not defined "deseed" is not available in the python console. it is only available in the terminal. --> How do I use the deseed command with a windows build? Use the command line of course. http://windows.microsoft.com/en-us/windows-vista/open-a-command-prompt-windowBring up the command prompt and run electrum --help for more information. |

Yes, I save the transaction to the removable media or at least I try to. But I don't think it gets signed because usually the suggested name to be saved is "signed..." but the suggested name is still "unsigned..." I hope that made sense.
When you load the unsigned transactions you see various input addresses. Are those input addresses present in your offline wallet? If they are not you should generate them: https://bitcointalk.org/index.php?topic=344115.msg3690179#msg3690179 |

All sorted! Thanks for the help!
Just one thing - if I have Electrum installed on both PC1 and PC2, I can control the wallet from either machine? Correct?
I'm just thinking, backup wise, in case something goes wrong with either one of the computers.
Yes. Backup the working electrum folder now. Then do two things: On PC2 where you have the working wallet view the seed and write it down on a fresh piece of paper. Your old seed backup was incorrect or you would have been able to restore the wallet. So make sure you get it right this time. On PC1 delete everything in the electrum folder except for the wallets directory i.e. do the same thing you did on PC2. See if electrum now runs on PC1. |

Sorry for not getting back sooner.... Anyway, I tried this, and I encounter the exact same problem when I do this. Electrum fails to start up on PC2. I swap back the Electrum folder that PC2 originally has, and Electrum opens - but that doesn't help, as my coins are in my PC1 folder. What's the next step for me to try? Thanks On PC2 locate the electrum folder that you copied over from PC1. Delete everything in that folder except the wallets directory. See if electrum will start up now and you have access to your coins? |
