Title: Help me relay a double-spend transaction Post by: yakuza699 on September 13, 2014, 10:41:52 AM Now before everyone's going to say double-spending is impossible i want to say that i want to make a double-spend attempt means one transaction will confirm and one will drop.
I had a success on double-spending these tx's f34a12f0c153055ef8d9ca4c917861de9130651495c21b9eba792050a07bfa71 (https://blockchain.info/tx/f34a12f0c153055ef8d9ca4c917861de9130651495c21b9eba792050a07bfa71),604ff6cb6b605420139adfbf91fd31266cdafcb7ccd163cfbdbdf5a4fa7a1881 (https://blockchain.info/tx/604ff6cb6b605420139adfbf91fd31266cdafcb7ccd163cfbdbdf5a4fa7a1881) but that was mostly a poor luck because Eligius and BTC Guild have forgotten about my first transaction which had 0 fee. What i want to make is either push two transactions at exactly same time that will both get relayed and get on the network but in the end only one will confirm or either discover a node which relays double-spend tx's and will allow me to double-spend that transaction at any time.I haven't yet tried Petter Todd's Replace-by-Fee Tools, Double Spend feature but that is just because as far as i can tell it creates two transactions one with low fee and one with big and i want to create two transactions which both has low fee. P.S What happened to https://blockchain.info/create-double-spend (https://blockchain.info/create-double-spend) Title: Re: Help me relay a double-spend transaction Post by: shorena on September 13, 2014, 10:53:40 AM uhm thats not a double spend. They use different inputs.
Title: Re: Help me relay a double-spend transaction Post by: yakuza699 on September 13, 2014, 11:04:12 AM uhm thats not a double spend. They use different inputs. You miss understood me https://blockchain.info (https://blockchain.info) doesn't show their double-spend tx's any more but those two separate transactions had their double-spend transactions and it was listed on their site the thing is that my double-spends were successful there was no reason for https://blockchain.info (https://blockchain.info) to list those other transaction anymore as they would have never confirmed.Title: Re: Help me relay a double-spend transaction Post by: shorena on September 13, 2014, 11:11:08 AM Maybe I dont understand, but what I see is:
TXa[1] that uses the output (0.06 BTC) form TXb[2] as an input and TXc [3] that uses the output of TXa (0.059 BTC) as an input and generates an output (0.058 BTC) that is spend in TXd [4] creating two new outputs of 0.057 and 0.0001, both currently unspend. A double spend would be if two TX had the same inputs, which makes it impossible that both will confirm. And frankly I would take anything bc.i shows with a grain of salt. I tends to be wrong on a regular basis. Most recent example would be the 6 orphaned blocks in a row. What exactly are you trying to do?

Right.Double-spending is impossible Double-spend attempts are possible and sometimes network confirmes second transaction, not the first one Quote but that was mostly a poor luck because Eligius and BTC Guild have forgotten about my first transaction which had 0 fee. Every node cleans its memory-pool from old unconfirmed transactions (usually small transfers with zero-fees).The difference is that some nodes keep such transactions for several days, Eligius does not keep zero-fee low-priority transactions at all. Quote What i want to make is either push two transactions at exactly same time that will both get relayed and get on the network but in the end only one will confirm or either discover a node which relays double-spend tx's Every node which does not keep transactions in memory pool relays the transactions which you call "double-spend".Quote and will allow me to double-spend that transaction at any time. You have to find not a relaying node, but a miner which uses "replace-by-fee" patch. I do not know about such miners, but this is allowed by bitcoin network and bitcoin protocol. As far as I know, biggest mining pools do not use this techinque.

Not true at all. Miners will confirm the transaction with higher fee. Or i can spend the change of that transaction(one of the double-spend tx's) and both tx's will get confirmed.What exactly are you trying to do? I'm trying to spend same inputs in two transactions.Title: Re: Help me relay a double-spend transaction Post by: amaclin on September 13, 2014, 12:52:32 PM Quote Miners will confirm the transaction with higher fee. Wrong.Today no one miner with significant hash-power does not use replace-by-fee patch. Miner either [accepts transaction and rejects all next double-spending attempts] or [drops low-fee transaction] In second case such miner will accept your "second" transaction Title: Re: Help me relay a double-spend transaction Post by: yakuza699 on September 13, 2014, 12:56:53 PM Every node cleans its memory-pool from old unconfirmed transactions (usually small transfers with zero-fees). OK than but why when i tried to push one of those transactions eligius rejected them (int -22) But this time it was a success i got this but why it rejected it before if you say that they don't keep this kind of transactions at all The difference is that some nodes keep such transactions for several days, Eligius does not keep zero-fee low-priority transactions at all.

Title: Re: Help me relay a double-spend transaction Post by: shorena on September 13, 2014, 03:02:06 PM A double spend would be if two TX had the same inputs, which makes it impossible that both will confirm. Not true at all. Miners will confirm the transaction with higher fee. Or i can spend the change of that transaction(one of the double-spend tx's) and both tx's will get confirmed.There cant be two with higher fee now can there? See the thing is every node that allready has a TX that spends input A will not accept another TX that spends the exact same input A. I have a feeling that you think "input" means "comes from this address" but that not true. Would a single input be accepted in more than one transaction you would be able to create bitcoin out of thin air. The protocoll is designed to make this impossible. Yet the term "double spend" is used in so many different ways. Maybe you explain exactly what your plan is. What amaclin suggest is IMHO not double spend as only one of those two TX will confirm.

See the thing is every node that allready has a TX that spends input A will not accept another TX that spends the exact same input A. Nodes do not relay "spam" transactions. Different node versions define the term "spam" differently.So, there are nodes which have tx1 and there are nodes which do not have it. The point is to locate these nodes and push tx2 to them. Quote Yet the term "double spend" is used in so many different ways. Maybe you explain exactly what your plan is. What amaclin suggest is IMHO not double spend as only one of those two TX will confirm. Of course. As I said earlier, double-spend is impossible in bitcoin. There is a probability to deceive the recipient of first transaction by sending another transaction which spends the same inputs. This attack is successful if the recipient accepts 0-confirmed transactions Title: Re: Help me relay a double-spend transaction Post by: DannyHamilton on September 13, 2014, 03:40:42 PM Yet the term "double spend" is used in so many different ways. Maybe you explain exactly what your plan is. Didn't he already explain that? Now before everyone's going to say double-spending is impossible i want to say that i want to make a double-spend attempt means one transaction will confirm and one will drop. He wants to broadcast 2 different transactions that are both similar size (in bytes), include similar fees, and spend at least 1 identical input. Then he wants just 1 of those transactions to confirm. From this description: What I want to make is either:
Edited by me for grammar and clarity. It sounds to me like OP would be satisfied if he could find software that would connect to multiple peers, and allow him to set up 2 different transactions that spend the same output, then broadcast one of those transactions to half of the connected peers while simultaneously broadcasting the competing transaction to the other half of the connected peers. (blockchain.info used to have a web page that would allow this. They seem to have gotten rid of it) It also sounds to me like he would be satisfied if he could find a mining pool that would accept "most recently received" transaction instead of "first received transaction", and if there were a way to send a competing transaction directly to that pool. (I don't think there are any such pools) It isn't clear to me if he would be satisfied if he could find a mining pool that would accept "highest fee transaction" instead of "first received transaction". If so, then he could try BitUndo (http://www.bitundo.com/). (although I don't think BitUndo has very much hashing power, so the likelihood that your replacement transaction would be confirmed is pretty slim). What amaclin suggest is IMHO not double spend as only one of those two TX will confirm. Correct, but OP only wants one transaction to confirm. He just seems to want at least a chance of getting a replacement transaction confirmed instead of its competing transaction. NOTE: Bitcoin is designed to make it VERY difficult to do what the OP is attempting. As a technical exercise, it is possible to write software that will broadcast competing transactions simultaneously to multiple peers, but I'm not aware of any such software that is available and safe to download and run. Aside from simultaneous broadcast, the other things that the OP wants to do would generally require waiting several days for the first transaction to be dropped from most nodes on the network.

Take two modern computers, connect them to internet, install Bitcoin-Core on both of them. Configure their .conf file to use many different peers (use -addnode and -maxconnections options), open console in both clients, paste raw transactions... ...place your right hand thumb on Enter key of first computer... ...place your left hand thumb...

Ok but how do i add that node? should i just Code: bitcoind -connect=respends.thinklink.com Or may be you are talking about any node? Yes i was talking about it, is it possible? I don't think it is.Let us connect our first instance to nodes running bitcoin v0.8.x (use -connect option) Is there a command like -connect=0.8.6 or should i just pick a random node?In the bitcoin network of course. Where else? Explain how to do that?

Ok but how do i add that node? should i just Code: bitcoind -connect=respends.thinklink.com I don't think that is the node itself, just a database, as it says in the description. Let us connect our first instance to nodes running bitcoin v0.8.x (use -connect option) Is there a command like -connect=0.8.6 or should i just pick a random node?Try

Ok but how do i add that node? should i just Code: bitcoind -connect=respends.thinklink.com Let us connect our first instance to nodes running bitcoin v0.8.x (use -connect option) Is there a command like -connect=0.8.6 or should i just pick a random node?Try https://getaddr.bitnodes.io/nodes/?q=/Satoshi:0.8.6/ Yeah that is basically picking a random node, but still thanks.Title: Re: Help me relay a double-spend transaction Post by: amaclin on September 19, 2014, 07:22:32 PM Quote I tried it many times before(with different transactions) i get the hash but i doesn't get on blockchain explorers such as blockchain.info, blockr.io and so on. You Quote So does it mean that my transaction will be mined? May be.Quote I guess only after nodes will drop the first one. There is no fixed time which nodes keep your transactions. Some transactions live monthes and years :) Especially on such stable pool as Eliguis ;DQuote Ops sorry forgot that it is above 3k bytes so now i put 0.0006 on it here It will not help. Remember rules: 1) Eligius rejects double-spend attempt transactions (this means also: Eligius does not have replace-by-fee-patch) 2) Eliguis relays all transactions which passed rule (1) 3) Eliguis keeps in its memory pool all transactions (+rule 1, 2) with fee > 0.0001 (and may be some with old coins and high volume) 4) Eliguis mines transactions (+rule 1,2,3) for 0.0001 btc per kb Now Eliguis already has either 65de3c6742428edf285aac19dda405bcd70d9b9ffa21f9755fe7c2d4440f77bf (you mentioned it, i do not know its contents) or 7a0b66873d85df5e14a5d67c46eb4de9a828dcef72f4b61399384f5f1ad7963c Update #3: Confirmed in block http://webbtc.com/tx/7a0b66873d85df5e14a5d67c46eb4de9a828dcef72f4b61399384f5f1ad7963c Thats all, folks!

Title: Re: Help me relay a double-spend transaction Post by: yakuza699 on September 20, 2014, 01:17:56 PM Alright this time i tried to double-spend this transaction https://blockchain.info/tx/93ea867e014898d17d9d2de9399b031cb16761b76627913fd075c2ab16034846 (https://blockchain.info/tx/93ea867e014898d17d9d2de9399b031cb16761b76627913fd075c2ab16034846) i put a generous 0.0005 fee on a 3006 bytes tx and pushed it on eligius i got this

Title: Re: Help me relay a double-spend transaction Post by: deepceleron on September 21, 2014, 12:51:23 PM Double-spending 0-confirmations is accepted as possible. Satoshi Dice was the first large player to experience the error of their ways in accepting 0-confirmation transactions - a player could immediately see that their bet (a transaction with low fees) lost, and then double-spend a much more favorable transaction that might be mined instead. Even a 2% success rate beat the house.
Bitcoin accepts the first spend of a UXTO that it sees, accepting it into the memory pool, and rejects later transactions outright. Miners are free to alter this behavior in their own software, perhaps accepting later double-spends that have more fee. It is not documented that any prominent miners have done so, because it against the interest of Bitcoin. The 0 confirmation "attack" (it's not really an attack, because you were warned) canonically takes the form: 1. Find a stupid merchant that will give you something irrevocable for a 0-confirmation transaction. 2. Discover something about network topology that allows you to narrowcast a payment to just the merchant or nodes around him, 3. simultaneously broadcast a double-spend transaction directly to mining nodes and their backbone. This may cause the merchant's Bitcoin to show the bad transaction and reject the later one more likely to be mined. Techniques to mitigate such an attack and still have some confidence in taking a 0-confirmation transaction within ~10 seconds of receipt involve employing many nodes and many connections to diverse nodes throughout the network which listen for any double-spend attempts and block the purchase if such an attempt is made. Merchant software should also know about fees and be less trusting of transactions without an adequate fee for immediate mining.

Up to you. It is certainly your right to do it on not.Quote as an attacker can read this topic learn how to double-spend Attackers do not read these topic! They do write it ;DQuote and attack those "stupid merchant's" which i don't really want as bitcoin will get a bad name for it. I think that the real attacker is much more clever than you and me.So, the real tools against them are truth, knowledge and publicity Title: Re: Help me relay a double-spend transaction Post by: yakuza699 on September 22, 2014, 05:37:40 PM Attackers do not read these topic!

So I created this transaction https://blockchain.info/tx/0c9b97eabf40271ef4f5061903e9731ac95d0bbe6bc9fb9e93fc9a18e16af2f2 (https://blockchain.info/tx/0c9b97eabf40271ef4f5061903e9731ac95d0bbe6bc9fb9e93fc9a18e16af2f2) I tried to double-spend it and pushed it on my bitcoin-qt debug console and got this 5d7a1d6a648fc1944c750e48c65e3204b09a2e93bdd4370c7666398e14b25508 but apparently it didn't got here http://respends.thinlink.com/ (http://respends.thinlink.com/) even though I left my client running for like 2 hours. So I fault maybe you guys could help me(and him) to return those coins by double-spending.
P.S I guess I haven't learned how to double-spend properly.

OK, you have got it.Do not just wait. Connect to as many nodes as you can. And rebroadcast tx manually.
