Topic: Bitcoin network very slow (Read 2186 times)

No.  There is no "official" website for viewing blockchain data.  blockchain.info is just a popular one.

Blockchain.info is just a company that has created their own custom bitcoin node software.  They parse the blockchain as it is created by miners and load the results into their own database.  Then they provide a website interface into their own database.

They have a reputation for having errors in how they parse the blockchain, for giving erroneous impressions about how bitcoin works from the way they choose to display the data, and for frequently getting out of sync with the blockchain that most full nodes recognize due to issues with their implementation.

There are other block explorers that are just as "official" (for example blockr.io and blockexplorer.com)

Real? Isnt the blockchain.info the official one?

and now, no fees ... is a problem with 2 transactions per seconde ...

use a real block reader : http://btc.blockr.io/
blockchain.info indicate somes problems ... sometimes (like thing that don't exist ... now).

Ok, then as far as I can tell, you have several addresses in your wallet (although some of them may be "change addresses" so you might not even know about them).

At least one of those addresses is the following:
14yp9sBcm4hTC8URqVbpaYhGoor2UQQsn5

That address has received transactions on 6 occasions:

Most recently, it received a transaction for 1.5 BTC from 1DfoamoFfKWXPvaCe2mBqRRU8qTXofZosr at 2015-02-27 04:46:09 UTC.

Those 1.5 BTC where spent in a transaction at 2015-02-27 06:07:45 UTC 55edfb4a8d4d1b74419a8d6a63fe1627d7f7ce586d6708ad4fbc4abd2ded2995).  In that transaction 1 BTC was sent to 13LHLzt7kppJibSUSMYV1MMVLrLXBek6DB and 0.4998823 BTC were sent to 1Lv6YSqxYrmZPrRU1N9uUTzBpwPLoJizPF (with the remaining  0.0001177 BTC being used to pay the transaction fee).  That transaction has over 500 confirmations.

This is NOT the transaction that you have posted here.

The transaction that you posted here (773b59bf596ffbfed0b84a04c739e4f23f390ec9dafb166e737c85234832a2ac) was sent at 2015-03-02 20:13:50 UTC.  It spent 0.08043999 BTC that were received in the following 3 transactions:

• 346b28808cbfd0e1e61485324ac48a398f814a76ecde85da113f4c0b39f0e350 (0.03967664 BTC received 2015-03-01 23:12:41)
• aabdcf499363e6b3d70bf06874297fb8d0417a9edf20a9f65899083137d56a15 (0.01972301 BTC recieved 2015-03-02 19:57:36)
• 3bdfe1621dd30511c0716984222cc943c4f7c68b417340c7dcdb819757f39e8f (0.02104034 BTC received 2015-02-27 04:59:57)

It paid a 0.00027225 BTC transaction fee, and sent 0.08 BTC to 1Hozfu5LLybgxvrEoaRDLo1YKcjiG4xhbh and 0.00016774 BTC to 1M3Tg9T1KSUw1RqPgoZmAgE9CgU9WTi2n6.

Since the 0.03967664 BTC from transaction 346b28808cbfd0e1e61485324ac48a398f814a76ecde85da113f4c0b39f0e350 are not yet confirmed, this transaction can not be confirmed.  That transaction (346b28808cbfd0e1e61485324ac48a398f814a76ecde85da113f4c0b39f0e350) did not include a transaction fee, therefore it is likely to take a very long time for the transaction to confirm.

If you are not the person that sent transaction 346b28808cbfd0e1e61485324ac48a398f814a76ecde85da113f4c0b39f0e350, then there is potential that the person that did send it could broadcast a competing transaction in the future before this one confirms.  If they do, and if that competing transaction becomes confirmed, then your transaction will become invalid and will never confirm.

If you are the person that sent transaction 346b28808cbfd0e1e61485324ac48a398f814a76ecde85da113f4c0b39f0e350, then your wallet will continue to re-broadcast that transaction indefinitely until it confirms.  This could be hours, days, weeks, or months from now.

This txn included no fee.  Miners only devote a small portion of the block space to free transactions so if there are other higher priority txn then you txn will wait.  Until this txn confirms, nothing 'downstream' of it will confirm either.  Once this txn confirms the downstream txns will confirm quickly if they have included a fee.  If you are using a client older than v0.10 I would recommend either upgrading to v0.10 or set a minimum fee for all txns.   Older clients will send high priority txns without a fee and nodes will relays those.  The issue is that each miner decides which txns to include and most only allow a small number of free txns per block.  Today txn volume is high enough that the number of free txn waiting greatly exceeds the amount of space set aside by most miners for free txns so it can take a very long time for free txns to confirm.  It is also unpredictable depending on your priority relative to other txns, the amount of space devoted to the miners who solves the next couple blocks and the number of txns waiting you could have free txns confirm quickly but you shouldn't count on it.  Most miners only devote ~50KB to high priority txns and the rest of the block to paying txns.  Right now the size of the free txns waiting for blockspace is more like ~560KB (or enough to fill 10x the amount set aside).

You really should consider free txns (even if high priority) to be 'I don't care how long this takes to confirm and I am patient enough to wait days or potentially weeks for this to eventually confirm'.  If that isn't the case I would pay the minimum fee as it is a small amount.  Also keep in mind that any change that results from that txn will also not be confirmed as well.  Your wallet will try to use confirmed change first but if you have only a few number of unspent outputs it may have no choice but to use unconfirmed outputs and then you run into problems like you encountered now.

Thank you

thanks



Try enabling coin control:
Settings -> Options -> Wallet -> check enable coin control features and click ok

If you now click on "Send" and "Inputs..." a window will open which shows you a list of all inputs (formerly received transactions) you can spend. If you set it to list it should show you some addresses labeled as (change), among them should be 15DokRs...

Bitcoin Core is using new, change, addresses on every tx.

Sorry, I am using Bitcoin Core version v0.10.0 (64-bit) at my computer under my control only

Wait!

Made a deposit?

Where?

What wallet are you using?

People here are all answering assuming that you are using a wallet where the private keys are under your control (such as Bitcoin Core, MultiBit, Electrum, or blockchain.info/wallet).

If you are using an "account" somewhere (such as Coinbase, localbitcoins, BitStamp, etc), and are calling your "account" a "wallet", then you are confused and contributing to the confusion.

Then it's your change address.
You sent 0.3 btc, and the change of  0.03967664 btc is returned back to your wallet.

That doesn't make any sense, there is no such transactions coming in to my wallet. I made a deposit of 1.5 BTC the other day and I am spending from that. There are no other incoming transactions.

I dont know, but the transaction in your first post (773...) spends 3 inputs and has 2 outputs. If a transaction has 3 inputs it is usually assumed that they are signed by the same person (in this case you). It is technically possible that several people could sign a transaction together, but in this case you would know about this. Anyway.

The input that was formerly received via 15DokRs... and has a BTC value of 0.03967664 is unconfirmed and thus the transaction (773...) can not be confirmed yet as it tries to spend this input.

I assume 15DokRs is on of your addresses. Either that or you are using something like SharedCoin.

Edit:


Thanks for the link. Its this TX to be exact -> https://blockchain.info/tx/346b28808cbfd0e1e61485324ac48a398f814a76ecde85da113f4c0b39f0e350

One of the inputs is ~2.5 days old (378 confirmations) and valued ~0.2 BTC, worst case would be 2.5 more days.
The other inputs is ~5 days old (756 confirmations) and valued ~0.13 BTC, worst case would be 2.7 more days.

If this estimation is correct the TX you are waiting for should be confirmed in under 3 days.

Edit2: you can see the priority here[1] and according to the wiki[2] it has to reach 57.6 million.

Check your address 15DokRsDh82fnyAt27T3vSVH7pC34qKRs3.
0.03967664 BTC you received there are not confirmed (0 fee, so it has low priority), yet you are trying to spend it.

I'm at a loss here, I have BTC in my wallet (all of which are confirmed) and I send 0.08BTC to an address and pay the maximum fee. So why do I have to wait for some other transaction to confirm???

I have no idea what you want to tell me with this TX, but its 4 outputs are all spend and confirmed. They are however not related to the TX above. I will not try to type the TX ID from your first post maybe you can post it.

Thats not the case because the BTCs I sent comes from this deposit:

Status: 543 confirmations
Date: 27/02/2015 04:46
From: unknown
To: 14yp9sBcm4hTC8URqVbpaYhGoor2UQQsn5 (own address, label: LocalBTC)
Credit: 1.50000000 BTC
Net amount: +1.50000000 BTC
Transaction ID: 111027bf19041b1cdd9a120d0a3d6a06027df04a0f8d2d21f51a2f7744235283-000

All the BTCs I sent have been confirmed as above

See the red U? You are spending an unconfirmed input. Your TX can not confirm unless this input is confirmed.

Whats happening to the Bitcoin network, I have made a transfer and paid the maximum fee and no confirmations for more than 1 hour?
