If you freeze an address its balance is NOT deducted from the total you see on the bottom left. Also there is a visual cue in a frozen address i.e. its colour turns to light-blue/cyan.

It sounds to me like you have a really old version of electrum. Usually it creates 5 addresses by default and more each time you receive money. So if you have just 2 addresses and no freeze option in the right click context menu then it sounds like an older version. What version of electrum are you using? The version number usually shows up in the window title bar but if it's not there you can find it under help menu > about

Another question. You say one of your addresses has a balance of 1BTC. How did you come by that information? Does it says so in the electrum window or did you look up the address on a site like blockchain.info?

Ask to speak to whoever is in charge of IT. There must be someone there who is in charge of that?

It won't cancel out the first wallet. You will be asked to set a password which can be the same as the one on the original wallet if you so choose.

If you don't want to restore from seed you can also copy the wallet file over to your backup system:

You can use blockchain.info's APIs. There are a bunch of different ones so take a look at all of them to see what's possible:

There is some advice and some scripts here:

Of course you should be very careful to read the code before you run it on your system.

They've probably got some group in their vast orgs working on it just in case. I bet for both sha256 and scrypt. They'll never let on though. Big companies usually have people working on all sorts of stuff in secret that outsiders never hear about. Some of these pan out. Most are discarded.

For example we now know that Nokia was working an Android version for years. They have now released it. Google's famous floating datacenter has been outed. Stuff like that.

the powers that be.

So the wiki's SSL cert is throwing these errors. Can TPTB please look into it?

Maybe Andreas just wants to meet the creator of bitcoin in prison. I'm sure he must be a fan

Why use them as fertilizer then? Eat them instead and ingest all that nutritious protein. Would you like that?

Python uses the OS libs. And Thomas is right about the version number not being a good indicator. I get 1.01e on opensuse too even though its been updated with the fix.


The built line seems more indicative

Say this individual you are dealing with wants to prove they sent you bitcoins. You copy paste the address from a block explorer like blockchain.info or your wallet's transaction history. The sig you get from him. If they match you know it's good.

If you just have the sig, and the UI doesn't force you to enter an address, then you have to verify the address in the sig with the one from bc.i manually. So, if the attacker has used a similar address, with say the same first few characters, you might be fooled.


Double click selects this which I think is base64:

This requires a triple click:

Hardly. They lend you money. You spend it on buying goods from China. Their economy grows.

If they turn to BTC they will still be sending you money. But it'll be going to a handful of early adopters and its deflationary so you won't spend as much.

The Chinese are focused on raising the profile of their own currency the renminbi. They've already done that to a large degree. It's climbing up the table of most widely used trade currencies.

My dyson sphere is bigger than yours!

If I were to stretch things a little I could say that a deterministic wallet is an example of unlimited addresses derived from a single private key. That private key is called a seed. Examples of deterministic wallets are electrum and armory. Try them out if you want to see it in action.

Be the first to spend the bitcoins sent there.

So many people justifying this. What next? Use decomposing corpses as fertilizer?

Start here:

Look at the historical difficulty increase numbers. Basically its rising 20% every two weeks and will continue to rise at that pace. For example recently 1TH/s miners were released. If you buy a mining contract at these prices you will loose money.

To install slowaes on a system with pip >= 1.4 you have to use the --pre flag. So as root:


You only need to do this for slowaes not for ecdsa.

Of course you should verify the sigs etc. before installing Electrum:

Usually this means that the wallet was not unlocked because you entered the wrong password. My suggestion is to run bitcoin-qt (the GUI version), pick an address and try to sign a message with that address. You will be asked to unlock the wallet then and at that point if you manage to unlock it and sign a message you know you have the right password. Then you can try to dump the priv key in the console.
