unconfirmedbalance shows fake amount (50.xxxxx btcs)

BitcoinUser2016 commented at 1:14 am on March 15, 2016: none

Hi,

I run a bitcoin server which have acting strange the latest 3-4 days. For some reason the unconfirmed balance when running bitcoin-cli getunconfirmedbalance shows up as 50.589243 BTC which of course isn’t true.

How do I reset this? Why did this occur? Tried both v0.12 and v0.12.99, same problem.

Thanks in advance, Nori

Are you sure the value is wrong? What sort of result are you expecting?

Did you try listunspent 0 to see if there is anything suspicious.

BitcoinUser2016 commented at 12:30 pm on March 15, 2016: none

Yes. I’ve never had this problem before. The volume is exactly the same. It’s been stuck at 50+ bitcoins for about 5 days now. There is no way 50 bitcoins have been sent to my wallet.

For example: When someone sends 1 bitcoins getunconfirmedbalance will show as 51 BTC and then go down to 5 BTC again once its confirmed.

Yes. Iv’e tried listunspent. Lists lots of transactions saying “confirmations: 0” which already have thousands of confirmations. Some dated 2015 with over 25.000+ confirmations and still says “confirmations: 0”. Like this one: https://www.blocktrail.com/BTC/address/16F4Bzkk6xaFktqSopACKn18rCRWCWgdW3/transactions “txid”: “a34a18358937a5b9a9fff8281491de57a9c7942217d43bb469eef5d5113d50fc”, “vout”: 1, “address”: “16F4Bzkk6xaFktqSopACKn18rCRWCWgdW3”, “account”: “usedaddress”, “scriptPubKey”: “76a91439811d6af01a4337137356cb88488f9f1b6348ed88ac”, “amount”: 0.23509566, “confirmations”: 0, “spendable”: true

It all started around 3 days after I’ve upgraded from 0.11 to 0.12. My wallet is around 20 MB. Should I rescan?

Conflicted transactions count toward the unconfirmed balance, IIRC.

sipa commented at 12:41 pm on March 15, 2016: member

That transaction is a double spend that did not make it into the block chain. 0.12 deals differently with those; see the release notes for more information.

Running with -rescan once will fix the problem, by explicitly marking it as conflicting with the block chain. After that, you can choose to remove such transactions from the wallet with abandontransaction.

BitcoinUser2016 commented at 12:47 pm on March 15, 2016: none

How and why does a transraction become conflicted? Will do a rescan then. Any idea how long this can take?

sipa commented at 12:56 pm on March 15, 2016: member

You always had these conflicting transactions in your wallet. Up to 0.11 they were just not counted towards your balance, as a heuristic was determining they couldn’t be accepted (they were not accepted into your own mempool). Due to the large changes that the mempool underwent in 0.12, that heuristic is no longer usable, so the wallet now tracks conflicts by itself. A rescan will let your wallet go through history and gather that information.

Closing this issue as it seems resolved (and you changed the title to something weird). Let me know if this is a mistake.

I recognise this is closed, but we have the same issue here and abandontransaction doesn’t seem to work. Here’s my command output

The transaction remains in listunspent, and the balance of ‘getbalance “*” 0’ remains the same. I confirm that I have run -rescan already on this wallet.

Any ideas what could be going on here? It’s remained in this state at least for 8 hours so far.

@morcos ^ Abandontransaction returns nothing, but still it seems that the transaction is not abandoned, any idea how to further troubleshoot this?

morcos commented at 3:38 pm on March 17, 2016: member

issue identified, working on a fix

morcos commented at 2:55 pm on March 18, 2016: member

@bittylicious #7715 should fix your issue. getbalance "" 0 and getbalance "*" 0 are unreliable and are not fixed. But you can use getbalance and getunconfirmedbalance. listunspent should also be fixed.

@morcos Wow, I am truly impressed by your commitment. Ever since I created this thread (and the weeks before that) I had to accept that I will always see a buggy unconfirmedbalance for some reason. Nor did a rescan or reindex work which was a pity since it took quite some time to redownload the blockchain. So, by coincidence I read the changelog for the latest version 0.12.1 and I saw this thread embedded.

Haha TL;DR: Thanks for solving this!!! I now have 0.000000 as unconfirmed balance because of your fix :D Finally!!! Keep up the good work guys. What you do for this community is truly amazing. Much love to you all. Take care!

You had better be sure you can prove that that balance was fake.I happen to no that it wasn’t and why would someone question someone else’s information without consulting with the owner first makes sense doesn’t it yes it does.

Please I’m in need of a fake generator . That can send coins to your block chain and it will show up and later disappear
