Hi so I am having an issue with my account.

I tried logging in but it was not working. I tried logging in and still didn't work so I went ahead and did a password reset and answered my secret question. I changed my password.

Once the password was changed I tried logging in and it still didn't work so I changed it again. After that happened it says my account is locked and to email themos.

I have emailed him but I don't think his mail provider accepted protonmail.ch? It has been a week now just want to check up if themos is there here to read these request.
PM and email theymos every week. He is a busy man and sometimes requests like these are lost under all of the other stuff.

Also, resetting via the secret question was what got you locked out. Due to the forum hack in May, the secret question locks accounts because they could have been more easily compromised from the hack.

Another member of this forum has been granted a name change: Blazedout419 has his name changed to Blazed .
For reference
how did that happen? I thought only staff and donators could change their names.
8943  Other / Meta / Re: Is there a way to be notified when you get a reply to a post? on: October 06, 2015, 12:03:18 AM
The watchlist and show new replies links will take you to the watchlist and unread replies respectively. They update every time someone posts a thread in a thread that you have watched (watchlist, default is watch a thread when post) or a thread that you have previously posted in.

There is also the notify option which can be set to send you email notifications for new replies in topics. Check the settings under profile.

contact their support. There is nothing we can do to help you.

You should probably stop using blockchain.info's wallet. They have had many issues in the past and recently.

I used to know 0.0001 BTC per 1000 byte. This site is showing 90 satoshis/byte. Which one is correct ? Any standard documentation available ?
There is no set fee. The recommended fee changes based on the market. If there aren't a lot of transactions, the fees will tend to go down. If there is a lot of transactions, the fees will tend to go up.
8946  Bitcoin / Bitcoin Discussion / Re: I successfully double spended $400 of Bitcoin today on: October 05, 2015, 10:12:44 PM
Have you reported this to blockchain yet? They should probably know that there is a problem with their system that allows spending unconfirmed transactions and creating double spends. Maybe someone should also write a fix and submit a pull request to their github repository https://github.com/blockchain/My-Wallet-V3

Edit: sent them an email to their security email. Hopefully the see it.

Hi.  You are telling me its not safe if i send laptop to repair shop then they see my electrum wallet?  Thus they could get my bitcoins if they wanted to?
It is probably safe if you have a password on the wallet. But they would be able to see how much you have. If you don't have a password on the wallet or if you have unencrypted backups, they could steal the bitcoin.

I am fairly certain foxpup is partially correct, and I think I found the problem. The issue is solving it. What I think happens is that the times are not synced. Google Authenticator uses Google's time servers, and btc-e (and every other site that uses google authenticator) must also use Google's time servers in order to generate the correct codes and have their time synced. The problem is that Google's timeservers are actually different from real time. They have slight changes (e.g. fix for leap second problem) that makes google time different from real time. The other issue is that your computer is not using Google time. The various chrome apps are all using computer time, not google time, so they are not synced and not generating the right codes. The solution is to find or write an app that uses google time for the time instead of computer time.

There are ways to track addresses, but it is a little difficult. Even harder is tracing it back to an identity although the address might have been posted somewhere like on this forum.

Possibly.
I'm guessing it's a company/business. I do not know many end users/members that deal with large volume of BTC.

There was mention of some txid tests/changes on the network a couple days ago.
Could this have anything to do with it??

Thanks Smiley
No, transaction malleability will not affect those transactions to change where they are going.

It looks like everyone's activity is back to normal now.

What happened to this taking a few hours?

On the plus side, I significantly improved the efficiency of the activity calculator which was previously sometimes locking up the whole forum for a few minutes.

Is there any way to view the progress of the recalculation?

I'm seeing it too. Reporting this to mods. Please move this to meta.
8956  Bitcoin / Bitcoin Technical Support / Re: Conflicted , Repeated Transaction in QT on: October 05, 2015, 01:35:13 AM
So it's just an attack on the bitcoin network to exploit a redundant and insignificant "security" flaw?
Meaning, there's no benefit or negative other than weird looking transactions temporarily?
Pretty much.

Although with any poorly written code, it can completely screw with it and in some cases, websites can be tricked that a transaction didn't happen. A scenario would be something like a website that you can withdraw bitcoin from is only checking one particular txid for the withdraw, not the balance of the address. Then if the withdraw transaction is mutated and then confirmed and the original is dropped from the mempool, the website thinks that the withdraw didn't go through and in their database it is canceled. In reality, the withdraw did happen, but the site thinks it didn't so the user can still withdraw the same amount. This is an extremely unlikely scenario, but it could happen with bad code.
8957  Bitcoin / Bitcoin Technical Support / Re: Conflicted , Repeated Transaction in QT on: October 05, 2015, 01:20:47 AM
Someone was doing transaction malleability attacks (thread here: https://bitcointalk.org/index.php?topic=1198032.0). This confuses most clients since the transaction ids are different. The two transactions appear as double spends. Don't worry, your bitcoin is safe. Transaction malleability only changes the txid, not the actual inputs and outputs, so your bitcoin is going to wherever you intended it to go originally. Just don't spend any Bitcoin from either of those transactions because only one will be confirmed and you don't know which one.

I have only ever sent BTC from this wallet to that one specific user, does this mean he specifically targeted me to perform this attack?
How can I prevent this from happening?
What would happen if he was successful, and how to prevent that?
No, anyone can perform a transaction malleability attack. Anyone can retrieve your transaction and modify it in such a way that the txid changes but not the inputs or outputs.

There is no way to prevent this kind of attack. The wallet should automatically clear itself up once one of the transactions becomes confirmed. To protect yourself, don't send any Bitcoin from any unconfirmed transaction (general rule of thumb anyways).

I use electrum and its great and easy to send/receive bitcoin.  There might be a chance I will be resetting my laptop and doing a clean reinstall install of my laptop.  its windows 7.  I believe as long as i have that electrum phrase... then i would be able to recover the bitcoin i currently have?  Thus whether its my computer that gets a clean reinstallation, or new computer or use someone else's computer... that would never be an issue?


So basically I would need the long electrum phrase and my electrum password and that is all?  So basically i would install electrum on laptop after the clean reinstall then put the 20 word phrase and then the electrum password and that is all?  Or is it a long process?
Yes, you only need the seed phrase. I don't think you need the password, but hold onto that anyways.

The other thing I thought about was wouldn't it be a better idea to send the bitcoins to blockchain in the meantime?  Thus send the bitcoin to blockchain and keep the bitcoin there.  Then once i get my computer clean reinstall, then send the bitcoin to my new electrum wallet?  Would it be actually recommended to use the same electrum wallet if doing a clean reinstall of laptop?
You could do that if you want to spend your Bitcoin while the computer is in for repairs. However, blockchain.info has a lot of problems, and I don't really recommend them. But there aren't really many other better alternatives then them.
8960  Bitcoin / Project Development / Re: [BOUNTY] for devloping/writing a script/code/program to dump all publickeys on: October 05, 2015, 12:03:41 AM
I wrote the tool using Java and Bitcoin core rpc. You can download it here: https://drive.google.com/file/d/0Bxw3ip9QfNOUWGZFWFN1alNjSHM/view?usp=sharing

There are 4 versions, linux 32 bit, linux 64 bit, windows 32 bit, and windows 64 bit. It also comes packaged with the proper jre for the program to run.

To run the tool, you need to run Bitcoin core in server mode (with -server flag or have server=1 in bitcoin.conf and have an rpcuser and rpcpassword set in bitcoin.conf) as well as with txindex enabled (-txindex flag in command or have txindex=1 in bitcoin.conf). If you are running it from the command line, you need to have the -reindex flag as well for the first time because txindex requires that Bitcoin Core reindex its databases to include all of the transactions. If you run it with the GUI, there will be a dialog that prompts you. The reindex will take a long time.

The program will work at any time during the reindex, but it will not be able to grab all of the data since the databases won't be up to date until it is done.

The tool works a little slowly, so be patient. You will need to run it for several hours in order to complete.

The usage:
Code:
Tool which scrapes the entire blockchain for all of the pubkeys of all transactions
Requires bitcoind (or Bitcoin Core with daemon enabled) and txindex=1 to be set in Bitcoin.conf
Usage: pubkeyscraper <rpcuser> <rpcpassword> [rpcport] [rpcurl]
<rpcuser>               Required. User of the Bitcoin-RPC server set in bitcoin.conf
<rpcpassword>           Required. Password of the Bitcoin-RPC server set in bitcoin.conf
[rpcport]               Optional. Port of the Bitcoin-RPC server set in bitcoin.conf. Default is 8332
[rpcurl]                Optional. URL or IP address of Bitcoin-RPC server. Default is 127.0.0.1

If this satisfies you, please send the bounty to the address in my profile.
