Hi
How encrypt backup of Bitcoin Classic?
Sorry for my question, I suppose there should already be a discussion about this but I cannot found some specific information.
Same as with bitcoin core, set a password for the wallet and it will also be used for the backup file. Keep in mind though that the wallet is only encrypting the private keys. If you worry about someone getting your addresses from the backup you should put it in encrypted container (e.g. using VeraCrypt). |

Hello all
I read that post, but i dont really understand that. I didnt linked my btc address to the user, nor posted it anywhere. What else can i do ?
When was the last time that you had access to this account? In most cases, if you can't sign a message, there is nothing that we can do. Who is "someone from DT" ? Please mark zombie007 as hacked, if you read this message.
There exactly isn't much proof to go by for now, I've left a neutral rating. Hello ! As i said i have some other proofs that i own that account. -Login ip-s i used my account in past 3-4 years -ALL the email history about private messages going up and down - i can make new photos with a paper with actual date of this air handler stuff i posted here: https://bitcointalk.org/index.php?topic=7216.msg11720493#msg11720493- i had some deals on the site, for example with JohnDow1968, he can help me prove that i own the account, i can talk to him via skype. ( https://bitcointalk.org/index.php?topic=1407373.msg14288708#msg14288708) -The last post i wrote: https://bitcointalk.org/index.php?topic=1559587.msg15680077#msg15680077 Now i cant login, and some fucking jerk using my account... -I sent my last PM to eliovp, asking him about nanos for sale, he answered me with the price, on 21th of august. PLEASE help. Send me a pic like this and Ill drop a negative rating on the account. I cant tell whether or not any of the above will be enough (or not too much) for an admin, but it can help the account not getting misused. Quoted just in case: Just finished my air handler, only 2TH, but expanding  The miners blow the hot air right into that metal air handler stuff, and a big mofo exhaust fan pulls out the heat. There are 9 "slots" on the air handler merger unit, 2 in use now. I will user 1 for each miner, probably for S5-s.

I suggest you talk to them, might get your account back faster than via admins. |

Is there any auto online sevice that rebroadcast my tx automatically every 6 hours?
Not that I'm aware of. any script?
I'm certain that people have written such scripts. I don't know if any of them are publicly available. Windows batch: @echo off
:start
echo ---
"c:\Program Files\Bitcoin\daemon\bitcoin-cli.exe" sendrawtransaction rawtxhere
echo ---
echo Time: %time% waiting 30 minutes
timeout /t 1800 /nobreak > NUL
echo ---
goto start
Ruby (can handle multiple if needed): require bitcoin_rpc.rb #https://en.bitcoin.it/wiki/API_reference_(JSON-RPC)
btc = BitcoinRPC.new("http://#{user}:#{pass}@#{ip_addr}:#{port}")
txs = Array.new
txs << "raw tx here"
txs.each do | raw_tx |
answer = btc.sendrawtransaction(raw_tx)
p answer #puts out tx id or error
end

That is why some scammer out there are doing it.. i just heard it in other forum.now i understand why we have double spend.. honesty when i was newbie last year never heard about double spending
This year starting on january i heard about double spending but i do not understand what it is actually..
Now i am confused because someone are not the same answer or different anser about double spending.. and main topic from other forum..
Now i asking that if i am receive the double spending which means the 2nd transaction win and i receive it but not deducted from sender?
If the 1st transaction is failed and the 2 transaction is win it will still be deducted in their bitcoin balance or there is no effect?
Hmm, there is no balance in bitcoin. Only inputs. Lets say your address is 1Abcdef... and someone sends you 0.1 BTC. You now have 1 input worth 0.1 btc. Lets say 9 more people send you 0.1 each. You have now 10 inputs worth 0.1 btc each. If you have another address 1Bcefg... and you received 1 BTC on that address with a single address you have 1 input worth 1 btc. Your total balance as your wallet would show you is 2 BTC, but when you create a transaction for a double spend its important to use the same inputs, because only then its the same coins. Thats why only one of the transactions can be valid. Balance is only shown to you so its easier to handle. Thats why we have wallets. |

-snip- This is the common misconception I think most of us here believe. The higher the fee, the faster the transaction. The next block has room for ~2000-2500 transactions (500-400 byte average), if your fee is high enough to be in the top 2000 its enough. You can pay extra to be top 10, but its still the same block. |

So, I'm not even sure if this is the right section for this, But here goes.
So essentially, I lost the password and seed for my electrum wallet, And am unable to access either of them ever again. The problem is, I've got about 0.2511981 in btc still in the wallet with no way of transferring it to a new wallet. I'm desperate for help here, And from my understanding, This is the only chance i have at ever seeing that btc again. So, I'm offering half of what's in the wallet to anyone who's able to crack the password and restore access. I know they could just take all the btc if they wish, But I sincerely hope that doesn't happen. Anyway, The wallet address is 1NqAUNtaAzKvrcdKWj9rhhc5Dncaefa5KR, And i desperately need access to these funds as soon as possible. I'm almost positive there's no way to restore my wallet considering I don't have the master key either, So this is really my only choice. Let me know if i need to move this topic, Until then, Good luck and thank you.
How much do you know about the password? Its impossible to "hack" a wallet from just the address. If you however know enough about the password, I can help you try a few billion combinations of possible passwords. You can even do it yourself, with tools like btcrecover. -> https://github.com/gurnec/btcrecover |

So it means the double spend if you send mistaken and double the send the only first send will confirm and the 2nd one will not confirm and it can be also possible to confirm?
Sorry i'm confuse i am always reading for some comments there but different answer that is why i didn't search it in our forum..
I heard that there is someone can scam for double spending?
I guess the scam approach is the simplest to understand. Lets say you are selling coffee and you accept bitcoin as payment without confirmation. Its coffee after all who has time to wait 10 minutes to get one. I am a scammer and order a coffee at your place. You show me the QR code with your address and the amount and I send with my phone as requested. The fee I pay you will be a little low, but your wallet will see the transaction, I take my coffee and go. In secret I have prepared another transaction that uses the same bitcoin, sends them to myself and pays a large fee. I send it into the network from my server that has plenty of connections into the network. Now its very likely that my 2nd transaction, the bad one, will reach most parts of the network before the 1st one. Whenever one of the transaction reaches a node the other will be rejected when it arrives. Its like a race through a maze. Each transaction blocks the other. My hope - as the scammer - is that the 2nd transaction will win this race and I get coffee for free. Even though I have only used the bitcoin once, this is called a double spend attack. If you wait for a confirmation you wait for the race to be over. You would know for sure which transaction won. In order to replace a confirmed transaction I would have to replace an entire block and thats very expensive. This attack is commonly called 51% or >50% attack, because it requires (in its simplest form) that the attacker has the majority of hash power. |

we all know that one of the factors that affect the speed of delivery of bitcoin is the amount of the fee we include.
so the larger the fee it will be more easily split the bitcoin block. so that will make financial transactions faster we sent.
No, your fee will not decrease the time miners need to find a valid block. It will only give miners an incentive to put your transaction into the next block. Raising the fee beyond a certain amount is pointless.
It is because that's the feature which makes bitcoin a secure digital currency. People have to wait because every single transaction needs to be confirmed by random people from all around the world. That's how it works.
At the very least this is misguiding, if not plain wrong.
I have not yet made a transaction where there is double spent but it's likely to happen so users should wait for the confirmation before proceeding,sometimes it takes long time to confirm but this is the only drawback but I still prefer to transact using crypto currency than paypal or payza.
If only you are in control of your private keys only you can double spend your transaction. Its always the person receiving bitcoin that has to wait for a confirmation, never the one that sends them. |

I just found it here block chain and check some more info how block chain works.. and now i saw this https://blockchain.info/charts/n-orphaned-blocksorphaned blocks chart. but honestly i don't know why we have orphan blocks.? I hope someone can give me idea about this or simple and easy explaination about this.. It can happen that two miners on different parts of the planet find a block at the same time or shortly after eachother. Both blocks are valid, but only one will continue the blockchain over time. The block that was not build on is the orphan. Do you have any other explanation i searched from google but i found many discussions. but actually i still do not understand. So if the two miners in different pool? Yes or two solo miners if thats easier to understand. How exactly the miner is organised does not matter. mined in the same time both blocks are valid?
Lets say you are a miner and find a block. Once you do, you send it in the network and everyone checks if its valid and if so passes the block along to others in the network. It takes some time until everyone in the networks has the block and has it verified. This is also true for other miners. Thus its possible that two different miners find two blocks. These blocks can be different, but have the same height (e.g. both are the 500,000th block). Both send them in the network and work on block 500,001. According to blockchain i saw this "The total number of blocks mined but ultimately not attached to the main Bitcoin blockchain." So it means if you mined orphaned blocks it is valid blocks but it is not attached in blockchain?
Yes, there can only be one block #500,000, whoever finds block #500,001 first decides which is valid. Every block has a predecessor (identified by block hash). In our case each of the miners would work on top of their own block and all other miners would work on top of whichever block they received first. It can happen twice or more times in a row, but over time eventually one side will win and all other blocks become orphans. |

The sole purpose of confirmation on the transactions I learned here is that for a transaction to go through, you need to be confirmed to see if it really made through. Miners will try to confirm it. It's like validating if the transactions are real and if they really did it. Double spending will be prevented if the wallet has indeed that kind of amount. Depending on the transaction made. For small amounts of transactions, I think 1 - 3 confirmations are okay, but for large amounts, not only that transaction fee is higher, but also the confirmations should be bigger. Patience is a virtue.
For bigger amount I think its the same. Once you see that there are confirmations already, I think its ok, meaning it is already being processed on the system.But of course, we are very cautious , since it is a bigger amount. May I ask @shorena , the transaction size (in bytes) is directly proportional to the amount? tia No, a single input has 148 (compressed pub key) or 180 (uncompressed pub key) byte. An input can be worth any (valid) amount of bitcoin. A transaction spends inputs and creates outputs (~34 bytes each). |

Hi i just found some posted here in other thread and section about double spend but honestly i do not know what it is.
But i have idea that double spend means that you double your send bitcoin but i do not understand someone that why they need to wait for confirmation before accepting and the other said that they want to wait because of double spending..
So if the receiver receive double spending i think it is lucky that he receive double? am i right?
Sorry for noob question.. even i am sr.member i never experience double spending in my life..
No, the term double spend is used in a rather confusing way. A true double spend where coins are used twice is not possible in bitcoin. At least not after one transaction has a confirmation. While two transactions can spend the same bitcoin, only one of them can be confirmed. Whichever is confirmed first is the "correct" one, the other is invalid. Now double spend is commonly used to refer to a second transaction that is in conflict (neither is confirmed) of another one. |

Thats a really confusing sentence, but it sounds like you are trying to say that transactions need a confirmation in order to be check for validity. Thats not true. Every full node (e.g. the bitcoin core wallet) can do this, with or without confirmation. Miners will try to confirm it. It's like validating if the transactions are real and if they really did it. Double spending will be prevented if the wallet has indeed that kind of amount.
A miner cant tell how much bitcoin you have in your wallet. Depending on the transaction made. For small amounts of transactions, I think 1 - 3 confirmations are okay, but for large amounts, not only that transaction fee is higher, but also the confirmations should be bigger. Patience is a virtue.
Thats bullshit. Transaction fees have nothing to do with the amount of bitcoin you transfer. They depend on the size of the transaction in byte. |

Vielen für die zahlreichen und sehr informativen Antworten!
Werde gleich mit den Programmen loslegen und sie testen.
Nur damit du damit nicht auf die Nase fällst... ACHTUNG(!) sowohl bitcoin core als auch Armory brauchen eine vollständige Kopie der Blockchain[1]. Das sind zur Zeit mehr als 90 Gigabyte und die Daten müssen auch lokal verifiziert werden. Mit einem halbwegs aktuellen Rechner und annehmbarer Internetverbindung lässt sich das in ca. 8+ Stunden erledigen. Hab das vor einiger Zeit hier[2] mal Beispielhaft durchgemessen. [1] die muss nicht unbedingt dauerhaft gespeichert werden, das ist aber ohne weitere Einstellungen erstmal so. ist das bei Armory ncht noch immer so dass man den Bitcoin-Core laufen lassen muss mit der gesamten blockchain? Hab jetzt die neuste 0.95 noch nicht getestet, aber bei den älteren war das so das Armory nicht mit pruning im Bitcoin-core zurechtkam. Ob Armory mit nem pruned core zurecht kommt weiß ich nicht, aber selbst wenn runterladen muss man trotzdem erstmal alles. |

2. The criteria for choosing a global mod should not be who wins a vote (which are virtually meaningless due to the potential for alts), it should be based on who is qualified.....in other words who has the experience in moderating the forum (or other forums). Some of the main reasons why someone will become a non-local board moderator are that someone makes a lot of accurate reports, has a good understanding of the rules, and mostly maintain neutrality in disputes -- the criteria for who becomes a local moderator appears to be much more lenient. After someone has proven themselves to be a competent patroller, they should take responsibility for a few sections, then eventually have responsibility for major sections (including the marketplace and related subs, bitcoin discussion and the altcoin sections) -- until someone has successfully moderated one or more major sections for a "decent" amount of time, they probably should not be considered for a global moderator position for the most part.
I agree and like to add that a vote is mostly a popularity contest. I dont know how active - in terms of moderation - any of the mods are I voted for. My 1st vote went to mprep mainly because they have been around for some time and had - for me - noticable positive impact on the forum. The same is true for mitchell, lauda (lets not open the can whether or not they should be mod in the first place here as well) and achow101, from my perspective. I can say little about other mods, their activity and ableness in this regard. Does that mean they deserve the position less? No. I still voted, but I think it should stay an internal decision and it is my understanding that it still is. Well the majority of what the various moderators do is done 'behind the scenes' and the public does not know which moderator took a specific action. When a mod reports a post to the moderators who have authority to act in a section, no one else knows, when a mod moves a thread, much of the time, no one knows, when a post is deleted no one knows who deleted said thread. Thats exactly why I hope this decision will not be made based upon the outcome of this vote. Let the vote be the decider in case of a draw, but it should not be more. Speaking strictly in terms of what the various mods have done for the forum while wearing their "moderator hat" -- I agree that mprep has done a good job in cleaning up the altcoin sections; I agree that mitchell has used his bot in order to stop much of the 'backlink spam' from impacting most users; I agree that achow101 has used his "staff" title to help users filter out bad advice in the "help" sections, and leverages his expert technical abilities to give very good advice in the "help" sections.
My concern about making mitchell a global mod is that many months ago, he said that he mostly reads a few select sections (I am not sure if this is still true or not), so he might not be interested in reading threads outside of those sections, which would be necessary to handle reports outside of those sections. I would vote that archdow101 be made moderator of the dev & tech section without further consideration, and the bitcoin discussion section if he has an interest in becoming a global mod -- after he gets more experience in moderating a more broad range of boards, I would not doubt that he will become qualified.
I agree that archow101 is a capable mod, they did not get my vote because of the time served. I trust Mitchell that they - since they are willing to do the job - take the time needed to read up on sections they usually do not frequent. I would expect that of any (new) global moderator. |

there's a lot of inputs. probably 20-25. how do i find out how big it actually is? i can't find that anywhere in mycelium.
Mycelium won't tell you, but if you do some math based on the current lowest tx fee to get a transaction confirmed without any delays, you would get ~0.022 for 20 inputs and ~0.0027 for 25 inputs, assuming a single output. You could probably lower that to get it confirmed a little slower. But yeah, I can't see that costing $40 now. I have to guess here, since you didnt include the actual calculation, but your numbers seem off. 148 bytes[1] per input make a 20 input TX, including a 34 byte output, 148*20+20=2980 byte in size. With 25 inputs it would be 3720 byte accordingly. If we assume a reasonable fee of 60 satoshi per byte[2] thats 0.001788 BTC (20 inputs) or 0.002232 BTC (25 inputs) in fee. [1] most public keys are now compressed thus 148 instead of 180 byte. [2] https://bitcoinfees.21.co/ |

would you consider selling it or cold you make me one like that as it make remembering it easy pm me if you ca help.
I could make you one with 1oinkBob (exact case) as prefix for 0.2166. If you prefer a cheaper (shorter) prefix, contact me in my thread[1]. [1] https://bitcointalk.org/index.php?topic=1257817.0 |
