Jet Cash this has more to do with permissions you have on the phone. I had all kinds of garbage wanting to upgrade that where connected to google and did not want. It took a well to cancel them but worth it. Only issue is when you need to use any google product it wants you to upgrade everything.
You know updates are not bad for you, right? Its the way developers close vulnerabilities, among other things. |

I recently rebooted my computer in the hope that it will solve my GPU problem. I was wondering if, when I'll have entered my seed in Electrum in order to have my coins back, I'll retrieve all my previous addresses. Since I conduct a loan service, this could be really problematic. Anyone could help me  ? Yes, you will have the same addresses as before. The only difference is that you can set a new password. A simple reboot should not remove your wallet though. A reboot, as the way I intend it, will erase everything from my computer. I think that it was not the correct word. Maybe I should have written "reset". Is your answer still the same ? Hmm, reinstall maybe? But its does not change anything. You can throw a nuclear bomb on your computer as long as you have the seed you will be able to restore every one of your addresses. On a different computer though. You can test if you dont want to trust my word. Create a new wallet file from your seed. |

signature campaign, selling digital good, especially account
doing some load, here or on btcjam, selling stuff you don't need to, and do it here instead of ebay or wait for open bazar
another way would be to buy with discount on purse io and sell it with the original price etc...
Do you mean Bitcointlalk account? I do not see many trading of BitcoinTalk account in this forum. Are they sold secretly? No, bct accounts are sold openly in the digital goods section. |

1.2 Satoshi per byte looks really bad IMHO. According to "cointape"[1] you are among ~10000 other unconfirmed TX and with 1.2 you are on the low end. The picture is similar on my own node.  [1] they have a new url https://bitcoinfees.21.co/ |

I've created my wallet on Blockchain site...but now I have only 100k satoshis, so I think I can't make a double spend without money  The only thing I can do is wait  Blockchain site? Blockchain.info? If so get used to refering to them as blockchain.info, because they are not the blockchain. They will return your coins after 2-3 days, double spend makes no sense in this case. Just wait. |

You should always keep backups of your private keys, whatever happens to your wallet provider/computer/house you can always access your coins again.
ah ok so its the private keys that make the bitcoin uniquely mine? The private keys are whats required to spend bitcoin and what wallets manage and hide for you. Nothing on a private key is tied to you as a person. If you show it to me, I can control your bitcoins same as you. So lets say electrum disappeared (unlikely but who knows) as long as i have my private keys i could access them?
How would i go about doing that?
thanks
Yes, you can right click on an address in electrum, select "private key" and enter your password to let it show you. It will be shown unencrypted and in very common format (WIF = wallet import format) that is understood by almost all wallets. |

There is nothing official with bitcoin so its impossible to have an official facebook page for bitcoin. If you or anyone else want to make one, feel free to do so.

Ah ok, so my input is made by all the small transactions that I received!!! I didn't know this...so I only have to wait before someone includes this transaction in a block...  Then is better to receive one bigger transaction than a lot of small transaction! Thanks for the reply! Which wallet are you using? We might be able to tell you how to double spend your TX with a higher fee or if its better to wait to get your coins back. |

I'm very, very interested in one thing. I have already asked that and nobody gave me a distinct answer: how do transaction fees and mining correlate? Why is everyone saying that fees go to reward miners? Mining is a process of supporting and simultaneous generation of Bitcoins. Where on earth did fees appear in this scheme?
Who pays them and to whom exactly? And how they decide who deserves most?
Please answer me, because everyone who is talking about that is like implying this is something obvious.
A transaction has inputs (formerly received coins you now use) and outputs (coins you send to someone else or yourself). The fee is the sum of all inputs minus the sum of all outputs. Let assume you have 1 BTC you received via 2 transactions for 0.5. You want to send 0.9 to Alice and pay a 0.01 BTC fee. You would use both your inputs, create one output for 0.9 to alice's address and one output for 0.09 for one of your change addresses. Sum of inputs = 0.5 + 0.5 Sum of outputs = 0.9 + 0.09 inputs - outputs = 0.01 (the fee you pay) When your transaction is confirmed the "missing" 0.01 btc becomes available in the coinbase transaction for the miner (or pool) that found that block which includes your transaction into the blockchain. Miners can not cheat here, because it would make the block invalid and you cant cheat because it would make your transaction invalid. Edit: changed the fee to 0.01 because I constantly messed up the number of 0's |

In case of electrum the seed and a working copy of electrum software to easily extract the private keys should there be no more electrum servers. |

Hello, for example I send to someone some coins and its still unconfirmed, then I send some coins again but now to different address while the previous one is still unconfirmed. Will that affect the the first transaction? What will happen to the both transaction? Thanks in advance for answers It depends. When you spend bitcoin you spend inputs. Inputs are the coins you have received in the past. Lets make two example to make this clear. We assume no fees, because its easier. #1 You have received 1 BTC in a single transaction (1 input) in the past. You now send 0.5 to Bob with TX 1 and send 0.5 back to yourself as change. This is because you only have one input and it larger than what you want to send. The change will confirm when the TX 1 is confirmed. Its not separated. Many wallets will allow you to use unconfirmed change inputs, because they come from yourself and you should be able to trust yourself. Now you send 0.4 to someone else and have to use the change from TX 1 for it, because you have nothing else left. This 2nd TX needs the 1st TX confirmed in the same or earlier block in order to get confirmed. It will also create change. #2 You have received 1 BTC in two separate transactions (2 total inputs of 0.5 BTC each) in the past. You send 0.5 to Bob, there is no change. You later send 0.5 to Chloe, there is no change either. Both TX are independent and can confirm in any order. |

I want to send it to a single signature wallet so I can spend my coin as I dont think a multi sig wallet is what I require it generates a file called unsigned.txn and I don't understand what do with it from there and Im scared my coins are stuck in the wallet I just want to send them on to get spent it says it needs two signatures but I created the wallet myself what would the other signature be and how do I sign it? I don't usually post in forums and dont see how to add attachments of screen shots
You need to take the unsigned.txn and open it with the 1st wallet, sign it, save it as "partially signed tx.txn", open it with the next wallet, etc. until you have the needed number of signatures (commonly 2 for 2-3 multisig). Once you have you can broadcast it. |

mmh so klappts sicher mit Verkäufen ....
Bestimmt son Pausenhof-iPhone-Gangster ^^
ich frage mich halt nur warum solo miner sofort so arrogant mit dem duden kommt :/ wenn ich hier als nicht deutscher nicht posten darf soll er es sagen und gut ist Wo du herkommst ist egal, aber trotz deines edits ist noch immer nicht klar was Du eigentlich verkaufen willst. Was soll "appstore deutschland" sein? Google? Apple? Erdgastankstellen? Darüber hat sich o_solo_miner wohl lustig gemacht, deine Reaktion sind wilde Beschimpfungen. |

Wie wichtig ist so eine Node?
...wofür? Ohne full nodes kein Bitcoin, das heißt aber nicht das jeder einen laufen lassen muss. Ist es dafür gedacht, wenn man keine online Wallet nutzen möchte und seine Coins auf dem eigenen PC verwalten möchte?
Auch, aber es gibt auch andere "SPV" Wallets die kein full node sind. Oder kann Willi damit über seinen Rechner Solo Minen? Ja, lohnt aber vermutlich nicht. Ein full node ist ein vollständiger Knoten im Bitcoin Netzwerk und verifiziert jede Transaktion und jeden Block. Full nodes nehmen von ihren peers Transaktionen und Blöcke an und leiten sie weiter sofern sie den Regeln entsprechen. Miner (bzw. Mining pools) müssen zwangsläufig mindestens einen full node betreiben um über unbestätigte TX und Blöcke anderer Miner informiert zu sein und die eigenen Blöcke zu verbreiten. Ob ein full node auch eine vollständige Kopie der Blockchain haben muss kann man diskutieren. |

Hi All
Apart from monitoring the 'node' or your wallet you are connected to to see when a block s found is there 'log' or somewhere else eg Blockchain where you can view/monitor or even look at the history of found blocks ?
Thanks
Not sure I get what exactly you are looking for, but I think something like this[1]? [1] https://www.blocktrail.com/BTC/blocks/1 |

I believe that you would need to keep the whole history of a Bitcoin in the same chain, this would get difficult if you tried to combine coins from different chains in a new transaction. It's not the storage space that's the problem, and your solution wouldn't reduce that anyway. In fact it would probably increase it as you would need to add a chain identifier to each transaction.
I'm not suggesting keeping the entire history on a single chain. I'm saying the chains are independent, yet identical in terms of technical specs, and joined together in a wallet system. Yeah, but this also means 10 times (plus new overhead) costs for running a full node in terms of storage. |

This is most likely my next step figuring out how the security works. Little worried about it lately due to the amount of people I see on each channel when I check the wifi around me. Tells me that people are either getting stronger signals or there just a ton more people moving to the net around me. I can pick up about 4 households per channel.
If they run wifi on the same channel they are not in your network though. That might cause collisions and lower your bandwith, but its not a security risk. Other reason I was asking is I stopped into a bitcoin/atm type setup and they gave me the password to their personal wifi. Was faster than the cafes and I suddenly thought they could be exploited by allowing this in the future by a savy person no where near my ilk.
Most public wifi is separated from the rest of the network and just a gateway to the internet. If you have a somewhat decent router that can run e.g. OpenWRT (or if it has similar features by default) you can isolate wifi users from your cable network and each other. All that aside though, if you have no services (e.g. shared folders) you expose on your network there is next to no attack surface. |
