So what happens to the Bitcoins that have been awarded to the miners in the short fork?
They no longer exist, the reward went to another miner. Newly mined coins are considered "immature" for 120 blocks to avoid that they are used for payments that could become nil. |

So what happens to the blocks in the shorter fork? (and the transactions in those blocks)
The blocks are considered orphans and will be forgotten. If your version of bitcoin core was online durring such an event it keeps them AFAIK. The transactions that are not in other blocks are again unconfirmed and usually must be confirmed again by miners or resend by clients. Its more common that transactions are confirmed in both chains. |

I think they are looking for a wallet that is using the same kind of seed than electrum and as such can restore from an electrum seed. I dont think there is such a wallet, unless you know enough to convert the seed -> https://bitcointalk.org/index.php?topic=1000544.0multibit uses high deterministic seeds blockchain.info uses high deterministic seeds and so do hard ware wallets.. Be that is may, Electrums mnemonic is not used by any other wallet. Not even Electrum 2, but its able to work with electrum 1.x seeds. Electrum 2 and Mycelium use the same master private key, but you would need to extract that from the mnemonic first (hence my "know enough to covert the seed"). See the excel sheet in the linked thread. |

I think I understand. There is only one record of the transaction, but because nobody has failed it, all of the subsequent blocks are deemed to have confirmed it.
Subsequent blocks can only confirm it, otherwise they would either be invalid (because its a real double spend) or a competing block for the same spot. It is possible and it just happens that two blocks claim to be number n in line. Simply two miners happen to find it at the same time, both blocks have a different set of transaction they confirm, both can be empty or full. Both are valid and reward the miner with (currently) 25 BTC. Each miner continues with the next block on top of their own block, the rest of the network on the block they learned about first. These two competing chains (called forks) will eventually result in a single winning chain, aka the longest chain with the most work done. Most work done is important in this context due to possible difficulty changes. So just "more blocks" is not enough. It is however incredible expensive to reverse 2600 blocks, as you would have to do all the work (via hashing power) to find 2600 new blocks that are still valid, but use your replacement block as a reference 2599 blocks deep. Keep in mind that the rest of the world will continue to build on the 2600 blocks while you try to exchange them. Only when you replaced all of those block and superseded the rest of the world will your chain be longer and the valid one. |

Thanks for the answers, and sorry to keep asking questions.  So how does my node know that there are 2,600+ confirmations? Each of those must be stored somewhere. Are they all stored in my PC then? 2600 confirmations are: 1 for the block that has the transaction and 2599 for blocks that create a chain of blocks after the first. If you run a full node all those blocks are on your machine. If not, the wallet still keeps track of the number of blocks found. |

I can do the translation, but not pass it around for you.

No wonder the blocks are so large if over two thousand blocks contain details of each transaction.
No only the first has the information about the transaction. The second only holds a reference to the previous block. Thus block chain. |

I'm running the latest version of bitcoin core, and I had an inbound transaction on 26/12/2015. So far it has had 2,636 confirmations. I suspect my understanding of trandsaction recording is flawed. I thought that transactions were verified by full nodes, and flagged if they were faulty for some reason. they were only confirmed when a miner added them to a new block that was added to the blockchain. It seems that this is not correct. If there are 2,636 confirmations recorded, then they have to be in the blockchain somewhere - or do they? So what is the entry in the miner's block that lets him grab the transaction fee? There can't be 2,636 nodes sharing one small fee.
A transaction is put into a block with its first confirmation. This is rewarded. Every following "confirmation" is just another block found on top of the block that has the transaction in it. That is not rewarded. Since the blockchain can fork, its still important (to some degree) to track the number of confirmations. Its really uncommon now that a reorganisation of blocks occurs, but it was more common when the strength of the network (in hash power) was lower than today. Thats also why most wallets count the first 6 confirmations until they visually mark the transaction as fully confirmed. That your transaction is affected by a reorganisation of blocks is less common the deeper it is burried by blocks (the more confirmations it has). |

You need to use electrum. What does "no longer works" mean? |

Negative trust is not moderated. Users are not banned for leaving (possibly fake) reviews. I haven't any exchange with him...He said I scammed him 0,1 BTC ... Its a trust system, not a trade feedback system. To have traded is not a requirement and could not be checked anyway. |

I'm thinking and thinking a lot about following thinks, maby you will call me paranoid but i thinking still about it 1) whats happen if tomorrow all BTC is 1$ worth? Thats not realistic. There are many people that would buy as much as they can at 100 USD or even 200 USD. It would if ever take a long time for bitcoin to fall to 1 USD. 2) what if all countries bills do crypto currency here in the mix bitcoins illegal?
Sorry can you rephrase that? I dont get the "in the mix bitcoins" part. 3) I can put my bitcoins in a physical product where I can graders me much better against the volatility that is bitcoin exchange rate?
No, you dont own bitcoin anyway. You just own (or know) a private key that allows you to spend certain coins. You can store the private key on a physical item (e.g. paper), but that does not attach value to the bitcoin. 4) The very best way to protect against a hacker attack or against a steal all your money from your wallet ?, are there any ways to choose a safe solution here?
I am a little worried about it and naturally want to protect myself as best as possible.
For most the safest solution is probably a hardware wallet. |

For one the TX is confirmed. Is it much faster if you run as a full node?
A clear maybe. If your full node is well connected to other nodes, this issue (bad network propagation) should be occur to you. Running a full node however is no guarantee for being well connected. I usually am, but I also read that e.g. people in china have problems keeping up with the blockchain, so a full node is no longer a valid option for them. On top of that if your full node is bitcoin core, it will rebroadcast the TX every 30 minutes. Thus, you can just keep it open and let it do its thing and the TX will propergate eventually. |

Dann hol ich mir jetzt auch mal die neueste Version. Hoffe, dass ich dann nicht auch die Probleme hab wie DS06  edit: Beim HD brauch ich kein Wallet-Backup mehr, sehe ich das richtig? Da reichen die Wörter, die man am Anfang bekommt!? Ich glaube die Wörter reichen... Aber so ein Quatsch hab ich noch nicht gesehn  Wo soll ich denn die Wörter speichern? Dann doch lieber ne Backup Datei. Allein schon die Optik, und die Symbole an sich. Und einfach ach... schlimm echt  Wörter + Zeitstempel reichen, am besten offline (papier o.ä.) speichern. Der Zeitstempel ist nicht kritisch soweit ich weiß muss man aber irgendwas eingeben. |

I have tried what you suggested, and the command returned me a keypoolsize value of "0". What does this mean? Can you explain why is it exactly requesting my password just to create a public account? I would like to not put my password everytime I want to create a public account, the less you need to put your pass the safer you are.
Bitcoin core keeps 100 addresses by default pregenerated for you. You can change this with -keypool[1]. If it would not do that it would require a password every time you clicked the "new" button in the receiving addresses window. This is because you cant have a new address without a private key. Well you can, but you would not be able to spend the bitcoin, so its not what anyone wants. Since bitcoin is not a HD wallet it needs to randomly generate and store every private key it manages for you. To store them safely they are encrypted with your password. Whenever the wallet is unlocked the keypool is refilled with new random private keys and addresses for them. This e.g. happens when you spend bitcoin or sign a message. Since you have used the hidden pool of available private keys (hidden key pool has 0 keys left) and addresses it asks you for the password to generate new addresses and keys. [1] https://en.bitcoin.it/wiki/Running_BitcoinOk so let me see if I understood this. It's asking for my password because it just means I already created 100 keys, so I need to put my password, then I will be able to create 100 more keys, and after I create those 100 more keys, I will be asked to enter password again (because keeypolsize is set to 100). Something like that? Anyway, so Im assuming its normal behavior and there's nothing to worry. Thanks. Correct. |

Disclaimer I didnt read most of the thread, but the amount of "fuck you" and the lack of even a single "thank you" I get makes me wonder if I shouldnt stop with this. Do you have hours to kill every day, for nothing in return besides a "Thanks!" or "Fuck you!". Or just let people decide for themselves?
Dont tag ponzis anymore, find out for yourself. Dont help in scam accusation, get the shit sorted yourself. Dont PM me with your bullshit anymore, get the shit sorted yourself. You wana be grown up? Fine with me, but dont you dare asking me for help. I have had enough of this whining and drama. |

Powerball is 1 in 292,201,338[1] A specific address is 1 in 2 160 = 1,461,501,637,330,902,918,203,684,832,716,283,019,655,932,542,976 Any used address[2] 1 in 2 160/0.5*10 6 ~= 2,923,003,274,661,805,836,407,369,665,432,566,039,311,865 So finding an address with a balance is ~10 34 times less likely than winning the jackpot for the powerball lottery.
