Other day I was thinking, where goes/stay the unconfirmed transactions? It stay on the blockchain too?

Well, maybe we can stop sending btc for 24 hours, one day per year to unstuck this transactions...

And what happens if we got a flood of 1 satoshi transactions without fee?

Unconfirmed transaction are not stored in the Bitcoin blockchain.
They are temporary held in the memory pool of all Bitcoin nodes in the network.
When a miner "finds" a block and "adds" transactions into that block, they are
removed from the memory pools and written into the blockchain.

After a few days, if a tx does not enter a block, those pending txs will be automatically
dropped from the memory pool and "returned" to the original address. Then the tx will
need to be performed again with an appropriate fee.

All txs that have no fee or a very low fee, are usually ignored by a majority of nodes
in the network. During "spam attacks" most nodes are set to ignore those "attack txs".

Thanks, I was thinking that this transactions will stay there on queue forever...

So if you need to send an amount without priority and put a very small fee, it will be back to your address if not confirmed? Have a exactly "days" to this amount return or is something randon?

Technically, the bitcoins never left your address until they are confirmed within a block.
Your wallet software just reduces your amount of bitcoins for appearances and convenience.
So, it never really "returns" to your wallet, since it never left, since it only leaves when you get
into a block. So when most nodes drop your tx, your wallet makes the hidden btc reappear.

But to answer your question, my understanding is that most nodes drop old pending txs after 3 days.

Also, it is important to remember that if you underpaid a fee and want to redo the tx, you can
perform a doublespend with a higher fee and it will cause the nodes to drop invalidate your old tx.

To avoid beeing blocked I don't like to use customised fees, I like to use recommended ones. I have experiences with unconfirmed transactions but at the end everything went well so I haven't experienced the loss of my coins because of fees.

Your post made me think,how about that scenario will happen. Is there a limit that if the transaction is not processed say for 3 days,it will be automatically cancelled? Can we have a blockchain holiday for one day in a year? Cheesy

This is very informative. I currently have a transaction which has been stuck for more than 36 hours. The weird thing is, I used the recommended fees of my wallet to send the coins over. Blockchain.info is saying that it is on medium priority and will confirm within 6 blocks. However, I think there has been more than 6 blocks since I sent it.

I got a few questions, I hope you can answer for me.

1. Can I cancel a pending btc transaction which has been stuck?
2. How do you double spend? Is this possible with every wallet? (I'm currently using bitwallet on ios)

Same here, i usually use Xapo for transaction but whenever i use blockchain then i just use recommended fees for the transaction and i never faced any problems like unconfirmed transactions or transaction getting blocked and never reaching the destination.

The Satoshi block limits makes sense when you see the stupid things being done to sabotage Bitcoin. The problem is, Bitcoin bounce back

every time, and these idiots just lose money. These tactics are part of a desperate group of people, who think this would bring down the

Blockchain. All the more reason to fight back harder than before...  Wink

... and some other nodes resend pending txs after 4 days  Grin

for example, go to https://blockchain.info/rejected
take the link with this comment "The Maximum Very Small Inputs Exceeded. Expected at least (150000) satoshi fee"
[copy] txid for a transaction which was rejected by bc.i today
then go to https://tradeblock.com/bitcoin/
[paste] the txid and get the original date when this transaction first time appeared on the network
have fun.

I think we should not alter the by default fee which is being shown in the wallets, when we send the payment. If the fee is low, it will take a lot of time for the confirmations to happen. And of course if the fee is nil, the transaction will never be confirmed.

Also i think if you want to give zero fee, you can use wallets like coin-base or Xapo, which offers zero tx fee for their customers

Luckily I'm always pay appropiate fee and never use custom fee that risk me many bad things such like slow confirmation.
And after I read this topic, I'm getting learn better and better about a fee

Just pay the fee shown by "estimate fee 25" or higher. Sure, it may look like a lot, sometimes many thousands of satoshis... but, that's one way to get included in a block.

Nodes do not continue to push txs that have already been propagated throughout the network.
They all pass it on until the whole node network is aware of that specific tx.

What you are pointing to are either custom programs that are either broken or being malicious,
and are purposefully pushing txs that are either invalid, too low of a fee, doublespent, or spam.

For the average user, their bitcoins will "return" to their wallets after 3 days.

I experience this happening few days ago that i pay low fee and it takes a long transaction to be confirm and according to electrum wallet that i use you can choose what block and fee you can set low fee within 25 blocks or below so i choose next block can be confirm and my transaction is fast than paying low fee..

Decided to end it with zer0 profit.

Nodes are not obliged to push txs that have already been propagated throughout the network.
But some of them have a patches which push non-confirmed transactions over and over again.
This behaviour is not invalid or misbehaviour.

What would be a legitimate reason to push non-confirmed transactions over and over?
Isn't re-boradcasting it over and over and keeping it in the mempool just adding to the
problem as to why it wasn't confirm the first time?

It is understandable if your tx is good and after a few days you repush it when a bottle
neck is over, but nodes pushing for weeks or months seems like misbehavior.

Do we need a reason to broadcast valid non-confirmed transaction to a peer?

No, it is not understandable.
You have a right to locate all such nodes and punish their owners.
You also have a right to keep forever all tx hashes for the transactions you have deleted and ban
the peers which re-send these transactions.  Grin

The answer to the flood of transaction would interest me very much. No bad idea involved of course Roll Eyes...
