Title: Bitcoin Transaction with decent fee stuck without confirmations
Post by: Get-Paid.com on February 17, 2019, 09:48:36 AM
The following Bitcoin transaction doesn't seem to get confirmed:

https://www.blockchain.com/btc/tx/40a076cced744360d130652ab146ab85d45028315657dea8c5c76b8593db892d

We have tried submitting it using the "ViaBTC" website to accelerate it - and the message says "Transaction has been confirmed"

But it has 0 confirmations and it doesn't seem to get any confirmations so far.

Does anyone have any idea what's wrong with this one?!

The last mined block was at 8:38 and your transaction was at 8:44....

So its normal. No blocks mined for over an hour, it happens sometimes. Nothing wrong with your transaction.

Last mined block: https://www.blockchain.com/nl/btc/block/0000000000000000001c08a03f45739692fa9e32e4b3684b7d8d97a405e7f23d

Your transaction: https://www.blockchain.com/btc/tx/40a076cced744360d130652ab146ab85d45028315657dea8c5c76b8593db892d

Look at the time received.

So why viaBTC says "Transaction has been confirmed" ?

No idea... could be because unconfirmed btc has been spend here: https://www.blockchain.com/btc/tx/c27c106a1ac754380b6f28396a8a8347cf35bf207a4ab4cd4ae902ddad34aead

Maybe they're wrong.

Recommended fees (https://coinb.in/#fees) dropped to 1 sat/byte after the last block was found, if the next block doesn't take too long, your transaction should be included.

There is a new block now, your tx was not included. I guess it will be in the next one though.

Could there be any technical fault with this?
Have you experienced something like this before?
Any feedback is appreciated, thanks.

It's normal. In the last block, this (https://www.blockchain.com/btc/tx/30c558171d742252947fc3e7eddef799cb41df41e8305d76de12b6092d4467e9) was the transaction with the lowest fee. It's still double your fee.

Since many wallets are trying to set "the best fee", fees tend to spiral upwards when the next block takes a long time to be mined.

I have exprienced this before, same problem and same reason: only 2 - 3 blocks / hour mined so confirmations are slow. Nothing you can do about it and nothing wrong, it just happens sometimes.

Look at the last mined blocks:

Quote
23 minutes - 2706 - Bitcoin.com
1 hour - 2887 - BTC.com

It's just slow... that's all.

If you're paranoid, you can keep track of blocks here :

https://www.blockchain.com/btc/blocks

You can see there's a 1h30min gap between the last block and the one after it, the network is having a hard time finding them.

Every time a new block is found, see if it included your tx.

Doesn't seem reasonable.

Quoted from user "franky1" in this post: https://bitcointalk.org/index.php?topic=5081853.msg48528029#msg48528029

Quote
blockchain rules are not 1 block every 10 minutes

its 2016 blocks every 2 weeks. coded
which only in the human brain but not in code calculates to AVERAGE 1 block ~10min

this means there are times a block can arrive in 2 minutes and another block can arrive in 18 minutes and on average thats 2 blocks in 20minutes thus still being ~10mins each

in the last 24 hours ~144 blocks should have been produced.
24 hours ago block 552871 was made
at time of posting 552994
123 block mined
=5.125 blocks an hour = less than 12minute average

if you check th other blocks before 552994(current block at time of this post)
552994    51 minutes ago
552993    1 hour 2 minutes ago (11 minutes before ..994)
552992    1 hour 6 minutes ago (4 minutes before ..993)
552991    1 hour 16 minutes ago (10 minutes before ..992)

so ask yourself before panicing.. why were you not screaming celebrations of the 4minute block?

infact lets look at a few more blocks. knowing 6 blocks are average an hour... yet an hour before ..94
552994 2018-12-08 06:50:47
552984 2018-12-08 05:50:52

means 10 blocks were made in an hour. thus the previous hour before ..94 blocks were being made in ~ 6 minutes


So yeah, it's kinda normal.
I have a 20 sat/b transaction also waiting to be confirmed. Just wait it out, when the blocks are found faster, the fees will drop and it will get confirmed.

Lol, what did you even mean by that? :D Sometimes the network is just having a hard time finding that new block, if you're mad about it invest millions into mining rigs and help the network out!

More miners won't change a thing, it'll only increase the difficulty so that the average is still 10 minutes per block.

Honestly I hear that statement a lot, but I would totally want someone to actually get the statistics for that. Is it really 10 minutes? For weeks now I'd say the average was more on 1 block per 20 - 30 minutes at best.

I know the difficulty scales with the network, but how that translates to 10 minute blocks is really doubtable..

I know the difficulty scales with the network, but how that translates to 10 minute blocks is really doubtable..

The algorithm works to make sure that, at every difficulty adjustment, the current difficulty rating would result in 2016 blocks every 2 weeks (as pointed out above), which works to an average of about one block for every 10 minutes IN THAT 2016-block period of 2 weeks.

But of course, as soon as the new difficulty setting is done, hashpower will increase or decrease. So if hashpower goes up, you'll find the average is > 10 blocks. If it goes down, it is <10 blocks.

Because this is so reliable, one can always calculate certain things, dates for like block heights and halving times. Dates will be approximate but accurate enough.

That's easy:
Block #563452 (https://www.blockchain.com/btc/block/00000000000000000020ecf3991ec380260bda6b05e4c78012d173b88e8a80ff) was mined at 2019-02-17 14:40:04.
2016 blocks earlier:
Block 561436 (https://www.blockchain.com/btc/block-height/561436) was mined at 2019-02-04 02:38:33.
That's less than 14 days ago, so it's less than 10 minutes on average.

Hey guys,

let me use this thread with an example of my own:

This transaction:

https://live.blockcypher.com/btc/tx/6368a3cbeb511ee63a01903169fb7654a21cbaedc96b87b4a2a77bb3951749dd/

Has a good fee but it is still with zero confirmations after 3 hours.

How can I investigate and check if this there is something wrong with it?

Thanks.

Immediatelly, after I posted, I got 1 confirmation.

It seems it is going. Slowly but going.

Thanks!

What a coincidence. (lol)

If you're in a hurry, you can use free Transaction accelerators like: ViaBTC-TxAccelerator (https://pool.viabtc.com/tools/txaccelerator/) as long as the fee is greater than 10sat/byte like yours exactly (24sat/byte).
If it was SegWit, the tx fee you've set might be different than what blockexplorers or accelerators can read; so if you want it to be >10sat/byte to be eligible, increase it to at least 20 sat/byte.
