2561  Bitcoin / Electrum / Re: [ANNOUNCE] Electrum - Lightweight Bitcoin Client on: April 10, 2014, 12:36:09 AM
Thank you for your help and encouragement.  I was unable to get command prompt working properly in XP.  I now have 8.1 and I can now get command prompt to respond to simple commands.  I just did some searching and all I could find was that command prompts for Electrum were unavailable for windows as of March 2013.  Are they presently available?  I would really like to setup an additional wallet.

Update to the latest version of electrum. The run it and choose file menu > new/restore. Navigate to a suitable location on your hard drive and enter a suitable name for your new wallet. Click save and then follow the on-screen instructions to create a new wallet. In future when you want to open this wallet either create a shortcut, as I mentioned in my last post, or use file > open.

The client does not communicate such data, and only data from the server can leak. Since the server does not know anything about seeds or private keys you don't have to worry about the latter.

Are you sure client memory can't leak to the server? There is this comment on reddit:

Quote
One of the factors of this bug is that vulnerable client applications may leak their memory to servers. As such, an evil server could potentially act as a honeypot, get you to connect via SSL, and then view a 64k window of memory from your client application.

2563  Bitcoin / Electrum / Electrum and openssl hearbeat bug on: April 08, 2014, 08:40:19 PM
So I imagine some of you have already heard about this new bug in openssl that allows you to extract the server's private key remotely:

http://www.reddit.com/r/technology/comments/22h163/critical_crypto_bug_in_openssl_opens_twothirds_of/

I imagine this affects quite a few electrum servers. Their SSL private keys may be compromised and anyone can impersonate them. That is a problem but not a big one because no one expects to trust these servers anyway.

But I understand this bug also allows a malicious server to read the client's memory. By default when you run electrum you connect to a random server via SSL. If you are using Linux on your desktop, running a vulnerable version of openSSL and connecting to a malicious Electrum server could this exploit be used to read your electrum seed or addresses' private keys?
2564  Bitcoin / Electrum / Re: Minimal fee on: April 08, 2014, 12:50:53 AM
I tried several servers by random. None did accept the transaction.

Set the transaction fee in tools > preferences. Then use tools > create transaction > from CSV text to create your transaction. Confirm everything is correct, sign and save the transaction to a file. Then open the file using a text editor, copy the hex portion and broadcast it using bitcoind or blockchain.info's pushtx:

https://blockchain.info/pushtx

Can you explain with example what is the hex portion of file.

It is a plain text file with a json object in it. It will look like this:

https://bitcointalk.org/index.php?topic=517006.msg5738256#msg5738256

You just copy the hexadecimal digits inside the quotes and paste into blockchain.info or eligius' push transaction page. Very simple.
2565  Bitcoin / Electrum / Re: Minimal fee on: April 07, 2014, 03:50:41 PM
Ok, I updatet / downloaded the new client.

Still doesn't work.

Did you try to send a tx with 0.00079 btc?

Try the steps I outlined. The problem is server side not client side.

Thank you again. Do you have a tipp which server I should try?

I don't know. You can try asking in the servers thread or the electrum IRC channel about which servers will relay transactions with 1,000 satoshi fees.
2569  Bitcoin / Electrum / Re: Minimal fee on: April 07, 2014, 01:39:57 PM
You will have to edit the source code to make this change. Edit the MIN_RELAY_TX_FEE line in lib/bitcoin.py. Change it to 1,000 satoshis:

Code:
MIN_RELAY_TX_FEE = 1000

Line: https://github.com/spesmilo/electrum/blob/c24482c21a7df7e7dc9d1027a738acfa49044a7e/lib/bitcoin.py#L680

The reinstall.

thank you
I did try it.
But electrum doesn't propagate a transaction about 0.00079 btc with this fee. It says network can't. With Bitcoin Core (0.9.0) it works

Try connecting to a different electrum server.

The thing is that you need a large portion of the network to be running 0.9.0 for the lower fee to take effect. That means miners but it also means electrum servers for us.

There is also the possibility that ccg is trying to steal from someone's wallet. We don't know him from Adam so how can we be sure? The 4BTC bounty makes me suspicious that he either a) doesn't value the coins because he stole them rather than earned them or b) he has no intention of paying out. Also what kind of person hands over some weird numbers that will unlock his wallet without any sort of explanation as to how to use them?

Seriously? It's not a bounty. It's a donation. Do you wan't me to send you the website remembering my friend. Not all people bad. Let me publicly post information trying to do something wrong. I am sorry you think that. Also, we mine coins currently and I feel that a 4 Bitcoin Donation would draw more interest in trying to help me out. I am more than happy to privately talk to you regarding any information you want.  I never thought of asking him while he was in the hospital to show my how to access them. People have more courtesy than that, or at least I do.  You need to trust people a little more. Yes, when I first jumped into the Bitcoin Community (because of my friend) I was Scammed out of a Big Chunk of money out of China. Am I still upset about this, Yes.  But not all people are bad. If you can help, I would be happy to donate to you.
Thanks for the input.
CCG

Rest assured I will NOT be helping you with this privately or publicly. I've said my peace and will bow out of this thread now.

Escrow is the way to go. There is a list of escrow agents here:

https://bitcointalk.org/index.php?topic=108716.0

Of course you should do your own research into an agent and not rely solely on the list above.

Multi-sig is also an option but it's complicated and not everyone will understand how it works.

Interesting thread. If $650 is the strike price then it'll have to hit $695.19 on the 15th for smooth to break even.

Use a BIP32 wallet for your site. Publish an extended public key. Then you extend that public key with the project ID to derive the public key for that project. Anyone can verify the public key using standard bip32 software and you get unique addresses per project.
