9761  Bitcoin / Bitcoin Technical Support / Re: [Urgent] Need help about Sending Transaction (Stucked) D: on: July 23, 2015, 02:05:37 AM
i have noticed that hash160 of both address are the same on blockchain (if anyone can explain me why): d8fafc8c4d94a2f46298fea7e8709e6f317a34da
I believe that is the case because the address is most likely a p2sh address with only one public key used and required.

3MUJYpyYTcsQAwSjjkA9tT5ByuwBuCZWXH - hash160 = 62a3ffb763b79b97352887bbba63c3f3de49f76f
1LnHdHV6uiZ25mkJceVZTpiFqPeUQvRiNY - hash160 = d8fafc8c4d94a2f46298fea7e8709e6f317a34da
Where did you get the 62a... hash 160? It doesn't match.

When my output is...

    "out": [
        {
            "value": "0.00180000",
            "scriptPubKey": "OP_DUP OP_HASH160 d8fafc8c4d94a2f46298fea7e8709e6f317a34da OP_EQUALVERIFY OP_CHECKSIG"
        }
    ]

it send to 1LnHdHV6uiZ25mkJceVZTpiFqPeUQvRiNY

...

Actually i want to send to 3MUJYpyYTcsQAwSjjkA9tT5ByuwBuCZWXH address... anyone know how can i do it?

Quote
something like

    "out": [
        {
            "value": "0.00180000",
            "scriptPubKey": "OP_DUP Huh 3MUJYpyYTcsQAwSjjkA9tT5ByuwBuCZWXH OP_EQUALVERIFY OP_CHECKSIG"
        }
    ]

Actually i have tried to send to another address like this one directly from blockchain.info, and it went fine...

D:
Do the same thing as the first transaction but instead of OP_DUP OP_HASH160 d8fafc8c4d94a2f46298fea7e8709e6f317a34da OP_EQUALVERIFY OP_CHECKSIG, do OP_HASH160 d8fafc8c4d94a2f46298fea7e8709e6f317a34da OP_EQUAL. That should work.
9762  Bitcoin / Bitcoin Discussion / Re: What Multi-signature really means & are they less safe ?? on: July 23, 2015, 01:24:09 AM
A multi-signature address is a special address in which you need 2 out of 3 priv keys before you can create a transaction with that address. With that said, any user who has control of a single key wouldn't be able to spend the balance on that certain address--that user needs another private keys to create a transaction. A multi-signature address is a safe way of keeping your balance. Just make sure that the private keys are separated so in case an attack occurs, you are able to still keep those precious btc's intact if ever the attacker only acquired one out of three keys.

So what I said is true about the Hardware wallets ? I gave an example with "Case" Hardware wallet and Iquoted since they control one key . and they got hacked and all private keys gets removed from their Database or wherever they store the private keys on their server .. does that means that we will lose our funds forever ? since they can't get our funds without us and we can't get our funds with them . Multi signature isn't really safe as I thought then ...
You are misunderstanding them and multisig. The multisig address needs 2 OUT OF 3 keys. THERE ARE 3 KEYS, NOT JUST 2!!! Case only has 1 of those keys. If they are like other companies that do this kind of stuff, then YOU WILL RECEIVE THE REMAINING 2 KEYS!!! You keep one key safe in a separate location while the other key is one that you use normally. That way, if their key is no longer safe or accessible, you can still spend your Bitcoin with the 2 keys that they gave you.
9763  Bitcoin / Bitcoin Discussion / Re: What Multi-signature really means & are they less safe ?? on: July 22, 2015, 06:32:40 PM
I never used any kind of those transactions of adresses , only on Bit-x.com and on BlockTrail.com and as most of you know ,those adresses starts with a 3 instead of 1 .

If basically Multi signature adress means having one private key with me and another with a friend or family member ... then how come we don't have control on a "part" of our private keys on Bit-x.com (this topic isn't about them , just giving an example)
basically what hacker need to do is steal the database and connect to our accounts (I know they have 2FA , just assuming)

I reading some articles on CoinTelegraph and jumping from a topic to another till I found my self on "The world's most secure and easy-to-use bitcoin wallet" which seems like it's this : https://choosecase.com/

when I checked their website I found this :
Quote

 We're building the world's most secure wallet platform. Case is a multi-signature, multi-factor wallet that requires 2-of-3 keys for a  transaction to take place. Each key is generated and stored in a different location and protected by a different authentication factor so there’s no single point of failure.
  • Dedicated hardware that's malware/virus proof
  • Case servers only control one key so we don't have possession of funds
  • Open source firmware and third party security audits of all systems
  • Designed to meet CryptoCurrency Security Standard Level III


Check the one on bold , What does that means exactly ? If they control one key and we control one key ... Let's say we are safe ,what if they get hacked I know funds won't be moved because it need our confirmation but we can't spend our Bitcoins either can we ? if the private keys on the Server-side was damaged or lost  Huh please explain and tell me if im missing something maybe
    
Since the multisig address only requires 2 out of 3 keys to sign the transaction, then if they were to say go out of business or get hacked, the only have 1 key so the attacker will be unable to spend the funds. However, they will give you the remaining two keys. That way, should they be compromised, you can still spend the funds. If someone is able to hack you, then they could spend the funds too. In that case, you should keep the keys separate. One key that you generally use, the other for backup on paper somewhere safe. That second key is only if the service is unable to sign the transaction.

Guys check this: https://bitcointalk.org/index.php?topic=1131135.0

Op is a scammer, do not engage in any business with him, i just found out this as well.
Interesting. Would he be able to scam Bitcoin from me with this group? I thought that this group would be using our own accounts and posting our own trades and such, so our Bitcoin is never at risk except from the trades that we do. Is this correct? If my money is not at risk of being stolen by funtotry, then I will remain in this group.

Why would you remain in a group with someone that is a scammer? The group was pretty useless anyways, whats the point of having a pump and dump group with, what? 5 bitcoins in total, what the heck are you going to pump with that, who knows what op's real intentions were.
True. Wouldn't want to be associated with a scammer. I was hoping that the group would be able to make some profits, but yeah, it doesn't really make sense to pump and dump with only a few Bitcoin.

Also, I just realized that since he would be dictating the coins, he could buy the coins before hand, tell everyone to buy that coin and he sells the coins that he has to the group, without the rest of the group knowing. Then he would have made some Bitcoin and he could run with it.


I will be leaving this pump and dump group.

Now on ssh starting the bitcoin daemon it shows:

Bitcoin server starting
$ Error: To use bitcoind, or the -server option to bitcoin-qt, you must set an
rpcpassword in the configuration file:
/var/www/.bitcoin/bitcoin.conf
It is recommended you use the following random password:
....

So I should put a bitcoin.conf in the /var/www/ directory, right?
You should actually move the .bitcoin folder from its current location to that folder. It should be in /root use chown to change the owner of the entire directory to be www-data. Use -R so that it does it for all files and directories in the folder.
9767  Bitcoin / Bitcoin Technical Support / Re: Having trouble with wallet.dat when generating with walletupdate over json-rpc on: July 22, 2015, 04:07:01 AM
That would be the simplest way, but the user www-data was created by installation of apache I think, so I donīt know where to find the password for www-data - and if I change the password over ssh I donīt know if the apache works well. Maybe you have a idea if thereīll be any trouble when changing/setting the password.
You can't sign in as www-data. Instead, login as root and type the following command:
Code:
su - www-data
That should change your user to www-data. Then just run bitcoind normally.
9768  Bitcoin / Mining / Re: Generate power from thermoelectric generator on a miner on: July 22, 2015, 03:56:20 AM
A lot of you guys are doubters, say that its not worth it. Screw the haters. I just placed an order for sidehack's usb miner, and I just placed an order for a fucking peltier device. Cost me 2 bucks on aliexpress.

Game plan:
  • Take off the heatsink
  • Duct tape on a peltier module
  • Let the magic happen

I have no idea what I'm doing when it comes to electronics, but next month I will come back to this thread, and I will fucking deliver. With pictures of the miner I probably just destroyed.
That is a cooling device right? It is similar, but not what I was talking about. I don't think that it is able to convert the heat to electricity, which is what a Thermoelectric Generator does.

How about a stationary bike that generates energy as you exercise?  This helps you lose weight and generating energy at the same time?
You can mount a bike onto a device that makes it stationary and is a generator. One of my friends has one. It can power a light bulb and provides exercise.
9769  Bitcoin / Project Development / Re: Need investor in BTC faucet on: July 22, 2015, 03:53:40 AM
I would be willing to invest, but I need more details. What website is this? Can you prove that you are the owner? How can I guarantee that you repay me?
9770  Bitcoin / Bitcoin Technical Support / Re: Having trouble with wallet.dat when generating with walletupdate over json-rpc on: July 22, 2015, 03:47:50 AM
@knightdk - Yes thats the manual way, but I donīt want to do this over ssh every time when I make a backup -  so the controlling should be only over the local webserver.

I search for a way to do this without write a program. Whats about a chronjob?
You could use a cronjob to execute a script. It could run periodically to both backup the wallet and change the owner.

Actually, why don't you just restart the bitcoind as user www-data? Then the back up file will also be owned by www-data. You would only need to change the owner of all of the files in the datadir to be www-data.
9771  Bitcoin / Bitcoin Technical Support / Re: Having trouble with wallet.dat when generating with walletupdate over json-rpc on: July 22, 2015, 01:29:46 AM
ssh into your server and use the chown command to change the owner of the wallet.dat to be www-data. In the /www folder, the command should be run as root, since root is the owner, and it should look like this
Code:
chown www-data:www-data wallet.dat

Now I really hope your wallet is encrypted because anyone who can access that webserver can download your wallet file.
9772  Bitcoin / Bitcoin Discussion / Re: Your first bitcoins came from.. (faucets aside) on: July 21, 2015, 07:37:59 PM
My first Bitcoin came from a sig campaign and doing stuff for people on this forum.
9773  Bitcoin / Bitcoin Technical Support / Re: Changing file name wallet.dat on: July 21, 2015, 07:32:48 PM
You can change the name of the wallet by using the -wallet flag every time you start the program. Something like this:
Code:
bitcoin-qt -wallet=newwallet.dat
Thanks, where can I type
Code:
bitcoin-qt -wallet=newwallet.dat
? Guess it's not in de debug console? Or is it via bitcoin-cli?
You do that when you start up the program. MZ posted above where to do that. In Windows, right click the shortcut for Bitcoin Core. and click properties. In the box where it says target, add
Code:
-wallet=<walletname>
at the end of the what is already there. Make sure there is a space before the dash. <walletname> is whatever you want to call the wallet. Click OK and then double click the shortcut to start Bitcoin Core.
9774  Bitcoin / Electrum / Re: HELP!!! BTC LOST after transfer from Electrum on: July 21, 2015, 05:24:40 PM
Are you sure that you had entered the right address? Where was the Bitcoin supposed to go? Looking at that transaction, it has been confirmed for a while, so whoever received has already received it and you should no longer see the amount you sent in your wallet.
9775  Bitcoin / Bitcoin Discussion / Re: Safety awareness of bitcoin users on: July 21, 2015, 03:38:49 PM
Will we get to see the results? There are many surveys and research things that go on in this forum and not many share the results. Please share the results with us.
9776  Economy / Service Discussion / Re: Stolen Bitcoin on: July 21, 2015, 02:24:13 PM
You probably got infected with some virus that either made the transaction for you or logged the password and the attacker stole some Bitcoin. I wonder why they didn't take all 14 BTC and only took 1?
9777  Bitcoin / Bitcoin Technical Support / Re: Need someone to build me a qt from github files with some changes I made. on: July 21, 2015, 02:07:53 PM
I can do it for a fee. PM me if you want.

Is that link the official source link? Do you have the link to a github or source repository? I would prefer to download the source from the source, not a third party.
9778  Bitcoin / Bitcoin Technical Support / Re: Bitcoin RPC command to export CSV file on: July 21, 2015, 01:58:53 PM

9779  Bitcoin / Bitcoin Technical Support / Re: Changing file name wallet.dat on: July 21, 2015, 01:53:06 PM
You can change the name of the wallet by using the -wallet flag every time you start the program. Something like this:
Code:
bitcoin-qt -wallet=newwallet.dat
It changes the name of the wallet but also needs to have that every time you run Bitcoin Core so that it doesn't create another wallet.dat file.
9780  Alternate cryptocurrencies / Altcoin Discussion / Re: Bitcoin WILL die. What is the best alternative? on: July 21, 2015, 04:42:37 AM
In reality, the entity would need 80, 90% or higher in order to successfully pull off such an attack. In the network's current state, that would be prohibitively expensive.

A flash jump in a fiat currency could enable the (more than less) trivial purchase of a substantial quantity of coins. These coins, alongside others acquired via (perhaps, "illegal") seizure and other, governmental mechanisms, could enable a governmental body to maintain instability in the exchange rate of the coin relative to the given fiat currency. This volatility could motivate a wider userbase of the given fiat currency to forsake any break therewith that said coin might, otherwise, facilitate.
I wasn't talking about the number of coins, I was talking about the hash rate. They would most likely need 80 to 90%or higher of the hash rate in order to successfully pull off such an attack that could stop Bitcoin. To get that much mining equipment and to maintain it all and to continuously mine to shut down bitcoin would be prohibitively expensive. The costs of running such a large mining operation would be too much.
