using either the Console in GUI, or the bitcoin-cli... You can use the dumpwallet or dumpprivkey commands (If you have a passphrase for the wallet, you'll probably need to unlock the wallet first) walletpassphrase "passphrase" timeout
dumpwallet "filename"
dumpprivkey "address"
"Passphrase" is pretty obvious  The timeout is the number of seconds to unlock the wallet for (ie. 600 = 10 minutes) "filename" is the filename to dump the ENTIRE wallet to "Address" is the specific bitcoin address you want to dump the private key for examples: walletpassphrase Th1s1sMy5uper5ecretPassPhrase 600
dumpwallet c:\dumped_wallet.txt
walletlock
walletpassphrase Th1s1sMy5uper5ecretPassPhrase 600
dumpprivkey 1BvBMSEYstWetqTFn5Au4m4GFg7xJaNVN2

creating a raspberry pi 3 bitcoin full node
but bitcoin core is now 140gb and usb i already have are each 128gb (256gb are $70.00 +)
how to add 2 usb each 128gb because when using both of them rasbian refuse to download entire core 140gb
any have a solution for this ?
Go and buy a 1TB External USB Drive... Get the Portable USB3.0 ones that don't require external power... or maybe even one of the desktop ones that comes with it's own power adapter if your Pi is power limited. I think that is a much more cost effective solution than attempting to use thumbdrives... Externals start at around US$55 on Newegg and Amazon... and will last for quite a while before you start running out of space for blocks. Trying to "pool" USB thumbdrives in some sort of RAID array does not appear to be a robust or easy solution and seems to require the use of slightly less common file systems... especially given the requirement for your pooled storage space to effectively be in the same directory (as all the blockchain files need to be in the same directory). |

Do you have any source of step by step how to merging bitcoin addresses into one address i got read some post the 1 input can decrease the transaction fee and would like to test and hope you can give some blog post or you can share step by step merging bitcoin addresses.
You don't "merge" bitcoin addresses. That is impossible. What you do is consolidate all your "Unspent Transaction Outputs" (or UTXOs) into a single UTXO... which is a complicated way of saying "Send all your coins to an address that you own in one transaction". A step by step for Electrum would go something like this: Step 1. Click on "Receive" Tab Step 2. Copy the "Receiving Address (TIP: you can click the icon at the end of the box to copy it to the clipboard)  Step 3. Click on the "Coins" Tab (TIP: if you can't see a coins tab, click "Wallet -> Coins") Step 4. Select all the UTXOs (Click the top one, then hold SHIFT and click the bottom one). Then right click and select "Spend"  Step 5. Enter (or Paste) the Address from Step 2. into the "Pay to" box Step 6. (Optional - For Experts Only) To reduce fees for this transaction, set the fee to 10 sats/byte (0.0001 BTC/kB). You'll need to disable Dynamic Fees and set "Max Static Fee" to "0.0001". Step 7. Set the fee slider as appropriate (if you did Step 6, set the slider all the way to the right so you can see the tooltip says "Fixed Rate: 0.00010000 BTC/kB") Step 8. Click "MAX" and make sure "Replaceable" is ticked.  Step 9. Click Preview to make sure ALL your coins are included, that there is only ONE output and that your fee has been calculated correctly. (NOTE: If your fee is too low, you won't be able to use the accelerator.) Step 10. Click "Sign" and enter your password as required.  Step 11. After the transaction is signed... RECHECK the transaction size and fee to make sure your fee is still AT LEAST 0.00010000 BTC/kB.  Step 12. If everything looks good, "Broadcast" the transaction. Step 13. (Optional - For Experts Only) If you set the fee manually to 10 sats/byte, go and use the ViaBTC TX Accelerator to push your transaction or you could be waiting a while for your transaction to confirm. NOTES/WARNINGS:- I will not be held liable if you attempt to use this method to consolidate your coins and you make a mistake and/or your coins get stuck.
- If you set the fees manually, make sure you calculate the fee correctly... otherwise your transaction and ALL your coins could get stuck for a while
- TRIPLE check the address you're sending to. You're sending ALL your coins, so you want to make sure they're going to the right place
- The ViaBTC TX Accelerator can be difficult to use as it is always busy, if you don't want to rely on it, then calculate and use "proper" fees based on network load or use Dynamic Fees and accept the cost

No. The BTC address you see is an encoded version of the "public" key that matches the "private" key. The private key (ie. "The Digital Key") is exactly that... private. You don't want that to be shared. You can derive the public key from the private key... but you can't get the private key from the public key. Which is why you can give your BTC address to someone, and they can't steal your bitcoins  AFAIK,Breadwallet does not allow you to export the private keys directly for your addresses. However, Breadwallet is a Heuristically Deterministic (or HD) wallet. This means that with the "seed" (the 12 words you should have written down and safely stored) you can always restore the complete wallet and all addresses it has (and will) ever contain. The seed is essentially the starting point that ALL the private keys in your wallet are generated from. Breadwallet uses "standard" BIP39 seeds... so should you ever need access to a specific private key for a specific address, you can create an offline copy of this website: https://iancoleman.github.io/bip39/Enter your seed where is says "BIP39 Mnemonic", click "BIP32" under "Derivation Path", select "Custom" from the "Client" dropdown box... and enter m/0'/0 in the Derivation Path and all your receive addresses and private keys will be generated below. You would then need to change the Derivation Path to m/0'/1 and see all your change addresses as well. So, to sum up... if you have the "12 word seed" that Breadwallet generated, then you CAN get all the private keys, Breadwallet just tries to keep them all hidden, which is a "Good Thing"™ |

hey hi-tec, I need only to save the seed for that wallet and I'll be safe right and I can restore it and log in it to other computers if I'm out of town? Just for the record... this is a really "Bad Idea"™ from a security stand point. You should never restore your wallet on someone else's computer... You have no way of knowing if the computer is infected with malware or keyloggers etc... and no way of preventing them from using data recovery techniques to recover your wallet file even if you delete it. Don't create multiple copies of your wallet unless you absolutely have to. |

The ByteBall airdrop allows you to just link all your Bitcoin addresses to your ByteBall address... Sure it is a bit of nuisance having to sign the message from all the different addresses you have, but it works.
As ranochigo and Kolloh have indicated, doing a consolidation transaction is possible, but can be costly in fees if the number of UTXOs you're consolidating is substantial. Having said that, at the moment the network load is pretty low... currently less than 5K unconfirmed transactions, so you can probably lowball on fees and still get confirmed... I'd recommend using at least 10 sats/byte (0.0001 BTC/kB) and then using the ViaBTC TX Accelerator to push it through.
Just be aware that as ranochigo pointed out, if you don't unselect the "use change addresses" option... and you create any transactions before the next airdrop, your coins will end up in a non-linked address, so won't be counted in the snapshot.

Is seed can be used to restore bitcoin from my electrum wallet even I will use other's PC?
Just as a side note, you shouldn't restore your wallet on someone else's PC. You have no idea if their PC is infected with malware or keyloggers and even if you delete the wallet file afterwards, there is a chance they could recover it using data recovery programs. Restore should only be used when you actually need to restore your wallet because you've got a new PC or your hard drive died etc... You should never use it to setup a copy of your wallet so you can access your coins when you're away from home etc. If you need access to some of your funds while you are away from home, you should consider getting a hardware wallet like a trezor or a ledger nano-s or possibly keeping a small amount of coins in a wallet on your mobile or something. |

When you create the raw transaction, try and set the sequence number to something less than "4294967295"... ie. less than the MAX_UINT32 value. (0xFFFFFFFF)
Looking at the RBF transactions that my wallet has automatically created via the GUI, they had a "sequence" value of : 4294967293
This seems to be the only requirement to mark your transaction as being "RBF".

Given the multiple instances of: 2017-06-30 06:37:23 LevelDB read failure: Corruption: block checksum mismatch
2017-06-30 06:37:23 Corruption: block checksum mismatch
it would appear that you have some corrupt blocks on your disk... it would appear that this may have occurred during a shutdown: 2017-06-30 01:48:02 Dumped mempool: 0s to copy, 0.312s to dump
2017-06-30 01:48:03 Corruption: block checksum mismatch
2017-06-30 01:48:03 *** System error while flushing: Database corrupted
2017-06-30 01:48:08 Shutdown: done
This seems to be indicative of either disk or memory (RAM) errors... https://github.com/bitcoin/bitcoin/issues/6528If possible, try running MemTest86 on your machine and check that your RAM is OK. |

Is there any way to recover the key?? Theoretically, yes... realistically, No. Given the keyspace is finite, then by trying every combination you would eventually find it. However, given the keyspace is so large, the sun is likely to have died and all life on Earth extinguished before you can test them all. How did you originally generate this "watching only" address? Did you originally have the private key held in a different wallet.dat file that has now been lost? |

All you seem to be achieving, is moving these user actions from your "wallet" to another app... you still need to tell the app to request the address... which is pretty much like being in your wallet and clicking "receive"... Also, personally, I'm not entirely sure I would want other apps to be able to interact programmatically with my wallet... #notParanoid It sounds a bit "edge case" to me, but then I don't have a need to receive a constant flow of payments for anything... you also would run into the issue of the "wallet" needing to run in the background as some kind of service or something listening for requests... which equals battery drain = death as far as mobile apps are concerned. Still, I'm sure if there is a great need for this, then it will happen... I just don't see an overwhelming need for this type of functionality at the present time. But then... I'm not everyone |

If your wallet is already setup, just make sure you have your seed written down and stored safely offline. That way, if anything goes wrong, you'll have your seed to restore your wallet...
It shouldn't make too much difference if you uninstall first or not...

As much as I hate to admit it... even a b.info wallet is technically "OK" when it comes to a fork... (NOTE: for the record, web wallets are still a really "Bad Idea"™ in general and you should get a "proper" wallet) b.info provides you with a recovery seed... which is a BIP39 compatible seed that uses the BIP44 Derivation Path of m/44'/0'/0'/0... so technically, you DO have access to the private keys for your account... in fact, you can just install Electrum, "Restore" your seed (selecting "Options -> BIP39 seed" during seed input) and you should be able to restore ALL your addresses/transaction history without having to send them. You can also get direct access to the addresses/keys using (an offline copy of) the BIP39 mnemonic code converter: https://iancoleman.github.io/bip39/They also give you access to the private key(s) for any address(es) that you have "imported" to your b.info wallet The result of all this is that leaving your coins in b.info "should" be OK if a fork occurs... just make sure you have your seed safely written down and stored offline... and have exported the keys for any imported addresses. |

Same thing happened to me and the transaction has been stuck, but already has 53,000 confirmations. It is only for $12, but still sucks...
This makes no sense... how can your transaction have 53,000 confirmations but be stuck??  If it has that many confirmations, it IS a confirmed transaction. Can you provide a txid for your transaction? |
|
|
|
|
Can you provide any more context? Like I said, it looks like it is related to VCC's... is the link being sold as some sort of method for converting bitcoins to cash or something? If you can't provide any further info,then I doubt anyone is going to be able to provide any more info.

Definitely upgrade... there have been some bug fixes since 2.7.9... plus the latest version fixes some problems surrounding Dynamic Fees... It is certainly in your best interests to stay updated.

Included In Blocks 473902 ( 2017-07-02 18:34:19 + 40,253 minutes )
40253 minutes = 670.883333333 hours = 27.9534722222 days... That is pretty much 28 days or 4 weeks to get that transaction through.  Looks like the mempool dropping down to under 5K unconfirmed transactions helped get this through... The miners just took what they could get! Hopefully this will serve as a lesson to all, make sure you use appropriate fees... and use a decent wallet that doesn't do stupid things like use unconfirmed outputs that use retardedly low fees!  |

Dude I have tried to accelerate this transaction but it failed in viabtc.com. It shows the pop saying transaction does not exist. I wish to learn about this. Why not be able to accelerate it first and how to transact with any other option.
If you read the miniFAQ on the ViaBTC TX Accelerator website... you would see the answer to your question: Why does it say “Transaction does not exist”?
In the following cases, you may be told that your transaction does not exist:
1) Too low fee: We only provide accelerator services for those with at least 0.0001BTC/KB transaction fees;
2) Node reboot: When a Bitcoin node is rebooted, synchronization of transaction data may be delayed. You can try again later;
3) Previous transaction unconfirmed. Your transaction can’t be confirmed if previous transactions connecting to yours are unconfirmed. You’ll need to wait till all previous transactions are confirmed first. You can also use our accelerator to help with that.
We can’t accelerate confirmation of “Double spent” transactions either.
The transaction I linked to has as fee of 0.00000000 btc. As such, it didn't propogate well... and ViaBTC refuses to relay this transaction, so it doesn't exist in their mempool... hence "Transaction does not exist". The OPs transaction will not show either, because of #3 in that list, it has unconfirmed parents... until all the parent transactions are confirmed, you cannot accelerate the OPs transaction using ViaBTC At this point in time, the OPs only choice is to use a place like BTC.com to push the parent transaction... currently their website is estimating this price as $5.86, which is actually pretty reasonable: Once that 0 fee transaction gets confirmed, the others in the chain should follow as they use OKish fees... the other option is a CPFP... but that will be a bit costly given you need to be paying fees to try and get 5 transactions confirmed! Also, in case it needs to be pushed again, the rawhex of this transaction is: 010000000167788f2160db9cef35b052738595d2f1e8a14f577ef7ceae86716e9f6a483fd5010000006b4830450221008e4743b0fa7d459677fe40674c33c5ba27cb5f01d829470ab4c6690e981979f0022068c4cf3715d262eeb43290608aa44114d29b8c678acabb9717ee1f438d353806012103340779d72a22757039632cc51a0e7ee2f775f6940d36776b8ce1128216c24a0effffffff027e8a0600000000001976a91482b565a53155012f0bc186706fdb2acc2851c6c488ac2fc07000000000001976a914cd2f4f91f8010f9a08c049ba17e983bd4de4b83588ac00000000 |
