Topic: Bitcoins not showing up on the blockchain? - page 2. (Read 3096 times)

Electrum is very user friendly, so after knowing the private key(the one you get from dumpprivkey) is pretty simple, I recommend it.

He's gonna open wallet (it doesn't matter if it's synced or not) and then console;
dumpprivkey inputaddress
it will return a string starts with 5
then he'll copy it and import into another wallet.

There're lots of topics about it.

how do we do that ? its actually really important hehe....

is there some guide ?

If you really need that bitcoin your friend can export the tx's input address's private key
and then he can import it into another wallet (electrum, online wallets etc).
Then send the amount to you.

Since the old tx isn't broadcasted yet,(new one) it'll be broadcasted and accepted.

we had to Re-Sync the whole blockchain now when the previous command failed.

If all else fails, simply backup wallet.dat, uninstall the client, delete the folder, reinstall and get a fresh copy of the blockchain. Also be sure to have non corrupted ram, or you'll get a corrupted blockchain often.

Yes, try checkwallet and then repairwallet commands.

This might fix the issue.

Getting worried now... Something like this actually happened before to, for a year ago. 2 BTC never got broadcasted or something

He tried. Client crashed and he had to make a restart... Hehe

Can he run:


In the console of the "Debug Window" in the "Help" menu, and let us know what the output of that command was?

Hey, thanks I will inform him of this, this is the txid he got
fa44f90816a02c4d4f96eb2361f4749a7c83311f8989a68c5172cc6903d64ae3-000

Since they sent the transaction before their wallet was fully synchronized, their wallet wouldn't have known about all the unsynchronized transactions.  Therefore, in the transaction being sent to you, it probably spent outputs that it thought were unspent, but that were actually already spent in the part of the blockchain that it hadn't yet processed. Then later, when it finally processed those other transactions, it likely became "conflicted" since it discovered that it tried to spend the same outputs twice.

If your friend runs their wallet with the -zapwallettxes command line option, it will "forget" all the transactions that it has built, and then it will re-scan the entire blockchain to rebuild the valid list of confirmed transactions that have been sent to and from that wallet.  When the re-scan is complete, they should see the coins are no longer "gone" (or if they are gone, then they should have the transaction history to see where the coins actually went).

If your friend is uncomfortable with running zapwallettxes, can you perhaps get your friend to supply us with the output after running the following command in the console:


Where txid is the transaction hash that their wallet says they sent to you?

That information should be enough to determine what outputs the wallet attempted to spend and why it was unable to do so.

But if so, I should see it with 0 confirmations right ?

Probably is the problem of only 8 connections, nothing to worry I would say.
But since the transaction is recent, just sit down some minutes and watch: your transaction probably got relayed now and a miner soon will put it on a block and it will get it's first confirmation.

Probably chain is not synced properly.
Before deleting all chain your friend should try those commands on bitcoin console;
salvagewallet
repairwallet

One of those will try to correct the wallet. if it doesn't work then it's needed to resync the block chain.

Some news. The wallet is uppdated. Coins are gone but no transaction took place. He said something about that the wallet said it was "conflicted" It was in swedeish so I'm just "hard" translating

This is the adress for those who would like to know

He had the latest version but had to re-update the wallet.

I'm not home yet not is he so we don't know if it's uppdated yet, tho it's been 20 hours something now.

But I'll send a update as soon as I'm home

ah yeah you are right, is this feature coming for the next qt version? would be helpful for certain situation

It's not likely but hope your friend hadn't a very old wallet,cause it could be forked, but don't worry,you have not lost it any way
