The unconfirmed transactions will disappear after a few days. The network will "forget" them and you can essentially double spend the transactions. If you look up the transactions in a block explorer, you can see whether your transactions are confirmed or not.

Pretty much all of those transactions are spam and dust transactions created and sent by whoever decided to spam the blockchain yesterday.

'["5K9T8VGcAztUQs5rSRGnf6oEwymY4k8YJV7MBfU5T3LD4H3wK2E"]' what is wrong ? Also tried to use this example 2 of 3 https://gist.github.com/gavinandresen/3966071The error message same 10:42:00  Invalid private key (code -5) What should I change ? BR! You are using the wrong private key. Since this is a testnet transaction, you must sign it using a private key in testnet format. The private key that you posted above is for the mainnet. Testnet private keys start with either '9' or 'c'. BTW, you should never post your private keys online. Also, I don't think you included the scriptpubkey or the redeemscript in the createrawtransaction. Be sure to do that. Follow Gavin's instructions in the link. |

You can enter a label if you like. This helps you keep track of your addresses. You shouldn't be able to type anything into the Address box, so just click "OK" and you will see the address with the label if you had one.
For sending transactions:
1. Go to the send tab
2. in the "Pay To" text box, enter the address of the recipient
3. In the "Amount" box, enter the amount that you wish to send. Bear in mind that you will have to pay a transaction fee, so don't send all of your Bitcoin because you won't be able to send.
4. Click "Send" It will open up another dialog box. Review your transaction and make sure you like it. There will be a transaction fee, usually very small. Click OK to send the transaction.

Is your code for this open source or available for people to download and run themselves? If so, where can I get a copy.

2. Either tradeblock.com or statoshi.info are behind this. They always show by far the largest values (tx/s and mempool size) and thus are always the sites that are referenced during these tests. It is a tremendous publicity for them.
I highly doubt that statoshi.info is behind this because the guy that runs the site probably doesn't have the money or infracstructure to carry out this prolonged spam attack. Possibly tradeblock, but still a stretch. Why would they want to anyways? Also, I think statoshi's data is more reliable than tradeblock's because it reflects the mempool of miners. Tradeblock's seems to be every unconfirmed transaction broadcasted which will include transactions that are dropped by nodes and miners. |

I don't think this is due to the spam transactions since it has been several days that they haven't updated. It might have something to do with their code since it stops at block 358999.

Priority is calculated with this formula priority = sum(input_value_in_base_units * input_age)/size_in_bytes where the base units are satoshis and input age is the number of confirmations. I don't remember what the thresholds are, but the lower the priority number, the more time it will take for a transaction to be confirmed. It may also be taking a long time to confirm because someone is spamming the network and creating thousands of unconfirmed transactions. This creates a backlog. |

Ok,
I just withdrawed Bitcoins from Virwox, it says 1-2 hours until itīs being transferred. Itīs now also listed at Bitcoin Core as pending transaction.
So, what is the usual procedure then?
A) Buy BTC at Virwox. Or any other exchange
B) Let Virwox generate a wallet adress.
C) Start Bitcoin Core, go to transfer, and insert wallet adress, the exact amount of requested money and a distinctive description.
D) Use the generated adress from the following pop-up to withdraw BTC from Virwox to it.
E) Then use Bitcoin Core similar to Paypal to send and receive money?
I modified your quote to what you actually need to do. You don't need to use the receive tab either. You can go to File > Receiving Addresses and see all of your addresses that you have used to receive Bitcoin. You can add another address by clicking the "new" button. It will give you another address that you can use. It is recommended that you use a new address for every time you receive Bitcoin, but there are cases where you can reuse addresses. Bitcoin Core will always use different addresses if you use the receive tab. Also, when you send Bitcoin, you cannot control which addresses the Bitcoin comes from unless you enable Coin Control in the settings. It will also send any left over Bitcoin to a new change address so don't panic when you see in a block explorer that your change went to another address. That address is still in Bitcoin Core and can still be spent from once the transaction is confirmed. |

I had 2 windows that popped up:
Window 1:
URI: ...
Adress: ...
Amount: ...
Description: ...
Message: ...
Window 2:
URI: ...
Adress: ...
Which of them do you mean?
Doesn't matter. As long as there is an Address listed, that is an address from your wallet. Any Bitcoin sent to those addresses will be in your wallet. To receive Bitcoin from Virwox, go to their withdrawal page and enter your Bitcoin address to withdraw Bitcoin from them. |

What transactions does it filter? Why would it filter transactions at all? |
|
|
|
|
What was the address they generated?
Also, as I said earlier, the request payment button DOES NOT ACTUALLY DO ANYTHING. You must copy the address from the dialog that pops up, go to Virwox, enter that address in their Bitcoin withdrawal page. Once that happens the Bitcoin will actually be sent to you.

Someone has to send you Bitcoin. Simply requesting a payment doesn't do anything. There is nothing and no one that will send you Bitcoin when you click request payment. Instead, find somewhere that you can get bitcoin from, such as an exchange. Get some bitcoin into that account and then withdraw the Bitcoin to your bitcoin address. You can get an address from the request payment button. It should show you a qr code and a random string of letters and numbers starting with '1' labeled as address. Copy the address and you have a Bitcoin address you can send bitcoin to and from.

So if mempool dependencies are already taken into account, then what does CPFP do? Best I can tell it adjusts the priority weighting calculate child and parent together. True?
I believe so. you can check the code from the pull request you reference above, it should relatively easy to figure out what CPFP does. To aid you in your search through the code, I recommend that you look at the docs for Bitcoin which can be found here: https://dev.visucore.com/bitcoin/doxygen/. These docs make it much easier to find things in the code. |

While Mandarin is spoken by the most people as a native language, English is most widely used worldwide. Mandarin is relatively concentrated, primarily spoken natively in East Asia. English on the otherhand, is spread out, primarily from the British empire's colonization. Even in places where the British didn't colonize, the rise of the Internet and the US has made English a prized second language. People in China are taught English as a second language while they are young. Go anywhere in the world and you will find almost everywhere people that have basic knowledge of English. While it is not the language with the most native speakers, English is very widespread. It is considered a Lingua Franca, a language used to make communication between persons not sharing a native language or dialect.[1] The word itself is based on French when French was used as a common language. English is typically used around the world between people as a go-to when they don't speak the same language. It is the primary language used internationally for business, politics, etc. Thus, it has in fact beat Mandarin in worldwide use, used as a second language for communication worldwide.

Would a block be valid if one of it's TXs (txid:y, aka "child") is spending outputs that are still in the mempool (txid:x, aka "parent")?
If the block was accepted then the "child" (txid:y), should it be reported as 0 confirms since it's dependent "parent" (txid:x) is still in the mempool?
The idea behind CPFP is that both transactions will go into the same block, thus confirming both transactions at the same time. A transaction cannot be considered confirmed nor added into a block unless its parent is also confirmed, be it previously or in the same block. |

Looks like there are over 11000 Unconfirmed transactions. There is going to be a huge backlog that won't be cleared until whoever is spamming stops.

There is quite a large number of unconfirmed transactions, 11800 and counting. This is creating a large backlog and is possibly why these transactions have not been confirmed yet.
