So, you're asking for "just" 0.08 BTC. At current preev rate, you're begging for a measily $650, just to identify an account that cannot be identified by this method... But you give your word you'll return the $650  I think what he is saying is that he senT bitcoin to that address, but his English is difficult to parse completely. And then is asking for help to figure out what web site it belongs to. Hmmm... Indeed, after reading your reply, i can conclude i might have misinterpreted the OP. I apologise to the OP. His problem seems pretty hard tough... The address looks like it's part of a very large wallet... The op can try out services like https://www.walletexplorer.com/address/14V6pKw3AaPcyRpqvff26B2eLdiNRJSz8b in order to identify the wallet... Following the above link, we can conclude following addresses are part of the receiving wallet: https://www.walletexplorer.com/wallet/0000fe51ae40e7cb/addressesIf you manage to identify one of these 237.000 addresses, you'll find the owner of the wallet... You can use google, or the searchfunction of this forum... with so many addresses, there is a big chance of finding a match. Good luck OP! |

AFAIK, even mod's don't have the privilege to look at the ip logs... Only Theymos and Cyrus can look at those (AFAIK).
However, if a sig campaign manager suspects you and your wife are alt's, and he/she asks Theymos to look at the ip logs (altough i seriously doubt Theymos has enough time to honour such requests to begin with), chances are you'll be kicked from the campaign and end up on the SMAS blacklist.

I don't know where they get this number: https://bitcoinfees.earn.com/At the time of writing, the optimal transaction fee for a 95% chance of getting into the next 3 blocks is 270 sat/byte. An average transaction is still 226 bytes. This comes to an optimal transaction fee of 61k satoshi's, that's 0.0006 BTC = about $5 at the current preev rate. If you use a segwit wallet, the fee is a lot less, if you're willing to wait longer than 30 minutes (on average), the necessary fee also drops. The only way to reach a $70 transaction fee is by using a massive amount of inputs/outputs, not using a segwit transaction and overpaying your fee Anyways, 5 USD is not the acceptable level either. And the rise of bitcoin price is no excuse here - with higher price, the miners should be happy to get equivalent USD fees, i.e. transaction fees should be accepted even in lower in BTC I do have to agree with you that $5 is to much... But miners are running a business. They make about 2,5 BTC/block in fees (at least, that's what i calculated a couple weeks ago). If they have sufficient high-fee transactions, there is no incentive for them to pick low-fee transactions and lose out on these fees. You have to realise nowadays, most miners are no longer idealists who mine to decentralise the network... Nowadays, the bulk of the miners are big companies that invested millions in ASIC's, and they want to make a profit (since this is their job, they do it to support their families, and the families of their employees). Even if the miners would pick, let's say, transactions with a 10 sat/byte fee, while there are 270 sat/byte transactions sitting in their mempools... Do you think the people that payed 270 sat/byte would be happy? They payed a lot of money to have a decent shot at getting a fast confirmation, i guess they would be pissed off if they saw block after block being broadcasted filled with low fee transactions while they were still waiting to see their high fee transaction end up in a block... |

I can connect a network of 2 Laptops, 3 Antminers and a cellphone and I mined 3-5 blocks / day. It's not the hardware that finds the bitcoins it's knowing where and how to mine. I hope I get my BTC though... Setup only 48 hours in. When should I get BTC in my wallet?
You just private messaged the person who wrote the mining software that has mined virtually all the bitcoin into existence over the last 6 years and told him he was wrong. I did and what's your reply.? Btw, a cellphone is marvelous at coding and deciding QR codes which communicate between computers far more like thought patterns, neuronal imaging. But the brutish, long form c++ you try to code after these things. It's like knowing how to talk but writing everything out with a dull piece of coal your commands. The computer wastes more time trying to solve how to find nothing from nowhere. What are bitcoins? 1mb?? 1.1mb? Hardly something anything with eyes in the deep web needs 100+ antminers to code out and connect with the long chain. But tell me, since you failed to reply to the private message. You found this thread pretty fast. Almost as if a solo miner had broken the record several times over using your network. You admitted the blocks were bitcoins, meaning I believe they generated in your network. I know I did the work, I believe I understand why I'm more proficient. Are you telling me now after... "That's a bitcoin block in the world...". - why because it generated the blocks in your address for the CK pool I was solo mining with? Or, you just found this thread immediately and got very emotional about it because... I used you network and no blocks have generated from the multiple detections my mining made? Again a bit coin is 1mb? A computer can solve that type of equation in seconds. It's locating them in the timeless and chaotic cloud that burns chips and melts hardware. So, you're saying absolutely nothing generated? BecUae I'm getting mixed messages by the fact you did confirm they were bitcoins, rather than the other guy suggesting I had made my own crypto, which I was quite sure wasn't the case. But try to understand my position, I've been working on network security and intercultural communication and language for a decade. I have some very big visions about solving some very serious problems humanity faces and it's not about adding a few zeros to my bank account. So, I fully believe in the capabilities and I of the power I am in service to. Being of service often gives one the ability to do things others cannot. If there is a creator, he cares more for those who serve. Now can you please clarify yourself, the CK pool receives or did not receive any of the blocks it told me I detected while mining through your network? BTW... How were temps with the hardware today? In order to mine bitcoin, you create a block header, composing of a version, the previous block header's hash, a merkle root hash of all transactions in your block, a timestamp, a target and a nonce. You then create a sha256 hash of the sha256 hash of this header. If the hash is under the target, you solved a block, you can now broadcast the valid block. If the endresult of your hashing function is bigger than the target, you have to increment the nonce and retry. There is no "magic". Unless you found a way to make a cellphone more power efficient at generating sha256d hashes than a device that has been designed for the sole purpose of generating sha256d hashes, it just cannot be done... It's "simple" mathematics. It can actually be proven that this is how it works (albeit not by myself). I fail to see what QR codes have to do with generating hashes. In my previous post, i did not know you were mining on ck's pool... Since you said you mined 3-5 blocks a day, the only reasonable explanation was that you were either mining on your own network, or you were mining an other low-diff altcoin. Now that you tell use you're mining on ck's pool, i have to agree with -ck: i can only assume you're missing some background information and you're assuming something wrong. That's no problem, everybody makes mistakes from time to time... But i personally wouldn't tell -ck he's wrong, since he knows much more about this stuff than 99,999% of the people on this forum, so when he tries to correct me, i'd personally give you the advice to listen to him... If you feel strongly that you have actually found a weakness in the sha256d algorithm, please post proof, and prepare yourself to get a free doctorate grant from several of the best universities in the world. |

Thanks Mocacinno
Nice piece of software.
Why do you state: "consider your hardware wallet as compromised..."
Greetz
Roland
Well, once you export even a single private key and store it unencrypted on a device that's online, there is a very remote possibility it was/is compromised. An attacker that steals this private key, and gets his hands on your xpub, can (theoretically, so i'm told) work back to calculate your xprv... It's basically just being paranoid, but i wouldn't want a single private key derived from my xprv from my hardware wallet ever to touch an online device... Odds are extremely small something bad will happen, but still, there is a very remote possibility. |

This transaction is indeed confirmed.
I assume 1L8CvwLjmGQfHqrAN3ez5tRArQxwqJPawi is the deposit address you got from the exchange, and i also assume you were using some kind of web wallet or exchange to send the BTC from?
If these two assumptions are correct, you need to double check that 1L8CvwLjmGQfHqrAN3ez5tRArQxwqJPawi is indeed your deposit address, and if it is, contact ucoincash, since the problem is located on their end.

Have you reported this to ucoincash if not Plz go and tell them about this.....
I just did, do you think it's a problem on their side? hard to say without a txid, but yes, it sounds like it's a problem on their side wouldn't be the first time an exchange's node was lagging... |

cupronickel is correct, i only wanted to add following remark:
There is no law that says the difficulty HAS to rise, nor that the cost of mining HAS to increase. As a matter of fact, the difficulty has dropped in the past (altough the general trend seems to be upward).
Also, when new ASIC's hit the market, they're usually a lot more performant (they produce a higher hashrate with the same power draw), so they difficulty can actually stay status quo while the hashrate (and difficulty) keeps rising, while in the same time the power use drops (so the average cost drops).

I need to export private keys for a pre-fork sweep of BTC to BTG. I use Electrum 2.9.3 with Nano S. Electrum menu does not show the option of Wallet/Private keys/Export.
How can this be arranged?
Greetz!
you can always use this tool, if nothing else works: https://www.ledgerwallet.com/support/bip39-standalone.html1) download the sourcecode of this app (look at the "Offline Usage" section) 2) disconnect your pc from the interwebs 3) run the tool (open the main html file you downloaded in step 1) 4) enter your seed (mnemonic) 5) look at the derived addresses/private keys, copy the ones you need on a CLEAN drive 6) reboot, reconnect to the internet, import the private keys 7) consider your hardware wallet as compromised... |

I guess I'm not understanding exactly how it works.
So where are the transactions stored? Nodes?
I was studying the mining rigs and noticed there aren't any hard drives on them.
So the mining is just computing the mathematical algorithms, and fills up nodes.
So where are the nodes stored?
Correct, Transactions are generated by anybody, then broadcasted. The nodes store unconfirmed transactions in their mempool. Once a transaction is stored in a block, it gets removed from the mempool (it's now a part of the blockchain, so there is no need to keep it in memory). The mining rigs = ASIC's => you are allmost correct on this one to, modern asic's have a "driver" (basically a small rpi), this driver has a small SD card to hold the driver's os, drivers for the ASIC, mining software and a small user GUI... This disk does not store any transactions on it tough, that's why your statement is still pretty good. You're supposed to either run your ASIC on a pool, or set up your own mining node and connect your ASIC to your own node. As for your last question: decentralised  Everybody can run a node (and many people actually do this). If you want to solo mine, or if you operate a pool, you'll have to run a node for sure... I see, and apparently there is sufficient redundancy should any individual node fail or fall off the system. I'll answer that question by posting a link  https://bitnodes.earn.com/Looks like there are almost 11.000 nodes at the moment... So indeed, if one goes down, it would not really matter. |

I'm unsure what you are doing... But it lt looks like you setup your own private network, and you're mining on your own private chain... If you pulled this off, you're probably having a really low network difficulty (since you're the only miner). This is why you assume the hardware doesn't matter (while it does matter). The blocks you'd find this way would not be valid on the main network. You have a short chain, and you're defenatly not going to pass any checkpoints that are hardcoded in bitcoin's sourcecode... But once again, i'm not sure what you're doing, it can be something completely different... The only thing i know is that with 3 antminers, the odds of finding 3-5 blocks in a day are astronomically small... Can you tell us a bit more about your setup (which client, which command you used to start your nodes, which peers, which ports, blockheight, network hashrate, difficulty,...) |

Hello. 6 days ago i send ETC from Myetherwallet to yobit.net exchange with 0.1 gas price. ETC didnt come to exchange but spend from wallet - http://prntscr.com/hblr01But Gastracker.io shows that the coins are still in the wallet and didnt show transaction to exchange - http://prntscr.com/hblxwfCan i rescue my ETC? Would be easier to help you if you provided the transaction id. Are you sure you sent to ETH wallet on yobit? I send ETC to ETC exchange adress. Problem is i dont have transaction id because gastracker.io didnt show this transaction. I am confused. you should be able to get the transactionid from myetherewallet* I agree with kahc, those screenshots are completely insufficient for us to get a grasp on your situation... They just show your balance, so we have no idear what happened EDIT * log in to myetherewallet * look for this text on the right: Transaction History * Click the link marked "ETH ( https://etherscan.io)" |

It seems like some of the posts in this thread are basically beating around the bush, and missing the most obvious point:
Any form of payment can be used to launder money... You can use cash to launder money, you can buy diamonds, gold, silver with illgotten gains to launder your money, you can launder your money by using online bank accounts in the cayman isles, you can buy prepaid cards with stolen money to launder your loot,...
Bitcoin isn't the problem, in most country's bitcoin isn't illegal... It's the act of laundering money that's illegal, it doesn't matter which medium you used to do this illegal act, be it bitcoin, cash, gold, silver or online banks...
So, if you ARE in fact laundering money, you will always have somthing to fear... If you are not laundering money, and you're not living in a country where bitcoin is illegal (and preferably a country with a working juridical system), you have nothing to fear... Sure, they can look into your transactions, but if you did nothing wrong, the worst thing that can happen is that your governement invades your privacy.... for me that's a big deal, but it will certainly not get you thrown into jail.

I will not advice for someone to have two bitcoin wallets on the same PC. Mistakes arise out of complications and it can be complicated when you have more than one wallet on a PC.
It’s is not allowed to make multiple. Account What? There is nobody stopping you from making as many wallets as you want. Sure, if you want to use centralised, insecure online wallet, you'll have to follow their rules, but if you make desktop wallets, there is no limit, unless it's a technical limit built into your wallet of choice. In this case, you can always change to a wallet software that doesn't have these limit in place. |

Hello,
I want to make a platform for a coin and have already the wallet for it and it connected to my website (with rpc).
I would like users to enter their private keys and then be able to send and receive money.
When they do it, I would use the "importprivkey <key>" command.
But with that command, their address/coins also would be saved in my wallet.
How can I remove their address after it from my wallet?
Also what's the difference between accounts and addresses in the wallet (it's in the wallet under "debug window" -> command "help")?
Last question: Is there a developer channel like slack channel or telegram group where I could get help from?
Thank you for answers!
I don't think there is a way to delete private keys using the standard json-rpc commands... At least, i have never read about such a feature. You used to be able to shut down your daemon, edit your wallet.dat with pywallet and then restart the deamon, but i haven't run pywallet in a long time, i have no idear if it would still work, but even if it did it wouldn't solve your problem. Also, do realise that when you import a private key, the standard bitcoin daemon will need to rescan the blockchain in order to calculate the balance, unless you run a patched daemon like bitcore and enable all those indexes. Thank you! Is there a way to run the user input only one time? For example, when you go to MyEtherWallet and enter your Privatekey, it shows your balance etc. for one time. But when you reload the page, it's gone. I don't think that they save my privatekey anywhere (except in a local cookie). How could I do this the same? you can run a patched bitcoin core that has an address index and transaction index option that can be set in bitcoin.conf For example, https://github.com/bitpay/bitcore-node/IIRC, it's forked from core 0.12, which is outdated, but should still be usable. If you run this version, you should be able to set following parameters in your bitcoin.conf: txindex=1 addressindex=1 timestampindex=1 spentindex=1 If you have these indexes, you should be able to immediately see address's balances without the need for reindexing. With these options activated, you should also be able to create raw, unsigned transactions using any unspent output(s) from the UTXO set, then in a second step use the private key to sign them without having to import the private key, and in a thirth step broadcast the signed transactions. Working this way should let you run your service without importing any private keys into your wallet, so you wouldn't have to clean up your wallet afterwards. Sidenote: i haven't tested these steps out lately, this comes purely from memory... It's always possible i made a mistake, or forgot some steps! I'd advise you to test this out on the test network, whose blockchain is a lot smaller, and a tBTC has no monetary value, which is also a big plus when you're fooling around with json-rpc querys |
