61  Bitcoin / Bitcoin Technical Support / How to sign existing transaction? on: May 08, 2013, 11:49:07 AM
How can I sign an existing transaction with zero confirmations with a different input easily?
62  Bitcoin / Bitcoin Technical Support / Did someone just double spend? on: May 07, 2013, 01:12:41 AM
I have a txid that I can get with gettransaction but get an "No information available about transaction (code -5)" if I use getrawtransaction, also the transaction has zero fees and doesn't show up on even though it was sent 4 days ago.

I had already spent it and have multiple stuck transaction on zero conf, I figured it's a little weird since I would at least have the key the transaction got signed with.
63  Economy / Service Discussion / How will 0.8.2 affect S.Dice? on: May 06, 2013, 12:26:31 AM
Wouldn't they still be able to notify players whether they lost or won simply by broadcasting the transactions without it actually being included in a block? (zero conf style)
64  Bitcoin / Bitcoin Discussion / ITT: Rate great ideas on: May 04, 2013, 07:23:21 PM
I am not the kind of person who likes to speak about things or people those are really useless conversations from my perspective I'm more of a person who likes to brainstorm and come up with new ideas to make money etc etc, most of the time the aim isn't even to make money but to contribute from a set of skills I am really well developed at.

I thought I can open a topic where we can all share our great ideas and give each other feedback on the ideas, hopefully playing fair and not stealing from each other.

My idea: a free iPhone/Android top-down survival zombie MMO(TDS?), basically you would be thrown into a sandboxed postapocalyptic world where BTC is used as the main currency and all the gov backed currencies are nothing more than a less convenient form of toilet paper, the unforgiving nature of the world would force players to form their own "cities" in order to defend themselves. The world is automatically economically balanced so every player can both deposit and withdraw BTC from the game. The balance is so thin that you would count bullets and salvage food in order not to die of hunger and start all over again.
65  Bitcoin / Development & Technical Discussion / Listunspent error on: May 03, 2013, 10:59:20 PM
Is there any way an "out" transaction could have gotten to listunspent?
66  Bitcoin / Bitcoin Discussion / IDEA: Bitcoin in Ultima Online on: April 23, 2013, 08:38:15 PM
It amazes me how no one has done this yet, it would be pretty cool if games had a dynamically adjusting economy, an economy so balanced that the "gold" within that MMORPG would become fractions of Bitcoins. This would give the Bitcoin economy a good backing as well as introduce a system where it is easy to purchase new items and no one needs to process the transactions manually, e.g. the whole global economy of that MMORPG would start at 20BTC, so when you kill a deer it drops 0.00000002BTC such as the economy is perfectly adjusted. If anyone here is a member on RunUO or played games like Ultima Online previously this should be enough to get your imagination rolling.

The whole system will be dynamically adjusted as captain Britain has originally intended to, same way Bitcoin adjusts itself.

  $arr = GetTx($client,$myAddress);
  $RawTx = $client->getrawtransaction($arr,1);
  $pieces = explode(" ", $RawTx["vin"][0]["scriptSig"]["asm"]);
  $myHash = hash('ripemd160',hash('sha256',$pieces[1]));
  $myHashStr = chr(0x00).$myHash;
  $myHash2 = hash('sha256',hash('sha256',$myHashStr));
  echo "Hash:".$myHashStr."<br>";
  echo "Base58:".base58_encode($myHashStr)."<br>";

function base58_encode($num) {
    $alphabet = '123456789abcdefghijkmnopqrstuvwxyzABCDEFGHJKLMNPQRSTUVWXYZ';
    $base_count = strlen($alphabet);
    $encoded = '';
    while ($num >= $base_count) {
        $div = $num / $base_count;
        $mod = ($num - ($base_count * intval($div)));
        $encoded = $alphabet[$mod] . $encoded;
        $num = intval($div);
    if ($num) {$encoded = $alphabet[$num] . $encoded;}
    return $encoded;

What is wrong with this code?
68  Bitcoin / Development & Technical Discussion / PHP connecting to Bitcoin (Solved) on: April 20, 2013, 04:23:44 PM
I am using:


require_once 'jsonRPCClient.php';
$client = new jsonRPCClient('http://user:pass@ip:8334/');

And getting the error Incorrect response id (request id: 1, response id: ) even though I can connect through my own ip using Google Chrome.

Bitcoind has * in the settings for allow ip at the moment
69  Bitcoin / Development & Technical Discussion / Bitcoin json RPC Client on: April 19, 2013, 05:49:06 PM
I am using jsonRPCClient.php, I have allowed the servers IP through the firewall and the config file and get Incorrect response id (request id: 1, response id: ), after doing the same with my ip I can connect through Chrome with the same string I put in jsonRPCClient(), what could be the problem?
70  Bitcoin / Development & Technical Discussion / How to run 2 bitcoin-qts? on: April 16, 2013, 01:04:25 PM
How can I run two separate bitcoin servers that accept json-rcp commands on a single machine?
71  Bitcoin / Development & Technical Discussion / Bitcoin cart on: April 15, 2013, 04:02:41 PM
Are there any PHP scripts that allow to receive and confirm (6 confirmation) without relying on bitcoin-qt running as server?
72  Bitcoin / Bitcoin Discussion / Isn't bitcoin getting greedy if you count the recent price rises? on: April 09, 2013, 05:06:39 AM
With the fees? I mean with bitcoins getting rare lately paying a 0.0015 fee for sending 0.01 btc seems a bit extreme, even if there are 8 inputs, paying 30 cents for a 2 dollar transfer is a bit greedy and even though I understand that this is necessary to decrease the size of the chain wouldn't it be possible to introduce different concepts in order to make the chain smaller? Possibly "timestamping" a certain point in the chain and deleting all the spent transactions before that and then using it as a new start? This could be done automatically every month for example.
73  Economy / Service Discussion / How does determines output? on: April 06, 2013, 06:24:39 AM
Analyzing raw transactions I can only see txid in "vin" but no actual address
74  Bitcoin / Bitcoin Discussion / Looking for freelancer on: April 05, 2013, 08:47:41 PM
I am looking for an independent freelancer to look over my bitcoin related C# code and fix bugs in exchange for funds, without actually having access to any sensitive information.

I am looking for well established members with similar experience who are primarily interested in creating something great rather than the funds.
75  Bitcoin / Development & Technical Discussion / Raw Transaction Tax on: April 02, 2013, 12:12:00 PM
How do you calculate it? I have searched google and on this forum and haven't found a single answer.

Are there any low level functions I'm missing?
76  Bitcoin / Development & Technical Discussion / Satoshidice tax on: April 02, 2013, 08:48:51 AM
How does satoshidice calculate and pay the tax on their transactions?
77  Bitcoin / Development & Technical Discussion / Get raw transaction JSON-RPC on: March 31, 2013, 09:55:55 PM
Doesn't matter if I use verbose or not I cannot get the raw transaction of "aff93d6d1dccb453b52818e931b6435b2ef84b3c386353cd9b027cd7323f5155" even thought it exists in the blockchain and has been included in the block 228966. I am using 0.8.1 and rescanned multiple times. Fork?
78  Other / Beginners & Help / Bitcoin won't show up on: March 31, 2013, 12:09:24 PM says it has been included in block #228673 even though me 0.8.1 bitcoin-qt has downloaded up until 228919 the transaction doesn't seem to show, have I encountered another fork?
79  Bitcoin / Development & Technical Discussion / Detecting incoming payments on: March 24, 2013, 09:19:08 PM
How can you detect every incoming separate payment when using just one address? The moment I hear about this I immediately think of local serialization, comparing them against listunspent etc etc. Is there an easier way?
80  Economy / Trading Discussion / What is the most efficient method of selling large quantities of BTC? on: March 22, 2013, 04:21:32 AM
Basically the subject line, also what are the benefits of using Skrill instead of PayPal with these trusted parties? Is the ol' meet and exchange applicable, how do you protect yourself in such events (sounds like a drug deal lol)?
