Bitcoin Forum

So I sent a payment to Bitmain last night.

This morning, I get an email saying that they never got payment.

Here's what my Bitcoin QT says:

Status: 0/unconfirmed
Date: 12/14/2014 17:46
To: Bitmain 12/14/14 - 18BE1CLw5cjDn7tEGuQssiS2g9GoAMsTBf
Debit: -1.243 BTC
Transaction fee: -0.0005 BTC
Net amount: -1.2435 BTC
Transaction ID: 0c79d295ad4732b416ae8ce5744c20b72f7dab31ec7a528ac06da8d7138cf66b
0c79d295ad4732b416ae8ce5744c20b72f7dab31ec7a528ac06da8d7138cf66b-000

Unconfirmed 0 / 6 confirmations is what it says when I hover over the transaction.

Never had this happen before.

Help!

No such transaction on the Blockchain, are you synced?

Yup

Have you checked your sending address(es)? Are the bitcoin still on there?

The coin is no longer in my wallet and the blockchain / Bitmain sees no transaction.

When "the coin" is no longer in your wallet, it has to be gone somewhere. It's not like "the coin" can just magically disappear.
Do you know, how the blockchain works? When there was Bitcoin send to your address it has to be send to another address to be gone.

Try entering your "sending" address to a blockchain service like blockchain.info and see where they went. I think they might be in a change address inside your wallet.

If you already tried running with the -rescan paramater, then since there are no confirmations...maybe you want to sign a raw transaction to respend these coins?

Here's a [GUIDE]

Or this one.

I do have a lot of addresses... No idea what my sendign address is.

I know a lot more about mining than I do about the blockchain that for sure...

I'll check out that guide...

Ok, so I followed the "open wallet waiting game" approach and left my wallet open and got 1 confirmation so far.

Thank GOD!

I normally wait a minute or so but was in a hurry last night.

I'm a mining veteran but a blockchain baby.

Never knew the wallet had to be left open for some time after a transaction... they're normally nearly instant.

Maybe I forgot to pay the miner fee this time?

Again, hurry last night so it's not impossible.

That's funny. I haven't heard about having to have your client open. It should go to enough nodes instantly.
Was your client synced, when you sent the transaction yesterday?

It isn't about syncing there, (reading the block histories), it is about whether your wallet's broadcast sent to nodes that propagated it out to ultimately be included in a block.  It will re-transmit if not.

To answer everything in one shot...

Not sure if my wallet was sync'ed last night but I closed it once I sent the transaction.

I normally only sync it once or twice a day because it's expensive to do so.

Fatigue took its toll on me and since I pay per bandwidth, didn't want to leave my wallet run all night.

So the network probably never got the query about my payment.

Bitmain has now acknowledged payment.

That was weird though lol

Glad I didn't start downloading stuff and tampering with codes... that's ALWAYS a last ditch effort.

Sometimes, less is more, just goes to show... an old gold mining mantra, again serves me well in Bitcoin.

Thanks to those who helped tho, I do appreciate it :)

Hopefully future readers will do what I did, just wait an hour or so with the client open and fully sync'ed.

Well, that turned out a lot better than I expected.

Wow scary stuff Gigabit!   :-\

Glad to see the confirms finally hit the Blockchain for you.  Personally if I send payments using Bitcoin Core wallet, I'll leave it up and running until I get that first confirmation at least.

Which miner did you spring for, if you don't mind me asking?

One other simple approach is to use something like blockchain.info to see if the tx has been at least picked up (you can right click on the transaction and copy its transaction id - when pasting that into blockchain.info just remove the dash and 3 digits it puts on the clipboard at the end).

Do a rescan on the wallet?

Well I'll be a son of a gun, if it ain't ChuckBuck!

It's one of those things that I needed to have had a bad experience with to remember to do it right in the future, could have been a lot worst.

The miner I went for this time is a C1 because I needed some SPI cables for an S3 and they wouldn't ship just wires without a fight so I gave in.

I also ordered an alternative (Swiftech) pump to try out in case the SysCooling one isn't up to my standards.

Doing an entire revamp in my mine from S's to C's (or such is the plan), that's why I am in the forum a bit more asking questions.

You solved my "networking kryptonite" and dogie solved my "cooling system kryptonite", so I'm that much closer to becoming a mining superhero  8)

Nice to see ya, hope your family's still alive healthy.

It wasn't showing originally in blockchain, that's why I was full of upside down question marks.

What happened is I shut off the wallet right after I made payment, kinda like you would in your online banking.

Too tired and didn't realize I needed to let the transaction propagate inside the network for it to work.

So the Tx was held in my wallet without it having had the time to alert the network of the transaction.

Or it's what makes sense in my mind...

Very possibly it was transmitted only to nodes that never passed it along to a miner for the next block.  This is where p2p is different from client/server.

Imagine if you dropped a song you wrote into a Napster sharing directory, and then turned off Napster.  No one would hear the song even if they wanted to and were already connected to your share.

The blockchain.info suggestion of using their wallet is that it allows the type of behavior that many are accustomed to with online banking.  Their servers will continue to transmit your transactions for 30 hours and only stop after that if it has not been put into a block sooner so you can close it immediately after sending as you did here.

You need to keep your wallet online till the 1 confirmation is done.

Not necessarily need to, but certainly best practice.

you should run bitcoin with the -rescan comnand it should resend the transaction .
also Bitcoin-qt will rebroadcast unconfirmed
transactions every 30 minutes or so. As
long as the sender has his client open,
the transaction will be rebroadcast.

It is not necessary if transaction was correctly broadcasted. All you need is to check your transaction in blockchain (https://blockchain.info) if it is appear.
