An Explanation of Unconfirmed Bitcoin Transactions : Coin ...

20 day old unconfirmed transaction (Bitcoin Core)

Edit: Issue resolved. The transaction was mined after my last comment below and when I got home from work.
So I have talked about this a few times in the past few weeks, where I created a 0 fee transaction, which was confirmed and now has 2830 confirmations, and 6 minutes later I created a low fee transaction, which has not been confirmed in 20 days.
I have no problem allowing the transaction sit in the mempool for another month or so, but how do I know it is still in the mempool? (I am using Bitcoin Unlimited 1.0.3.0). This unconfirmed transaction also means that more then .5 Bitcoin (Core) is being held up and I cannot send it to an exchange so as to divest myself of it.
Thoughts?

Where can I see the total number of unconfirmed transactions? Bitcoin is at 50,000 currently.

Is there a website like https://tradeblock.com/blockchain/ that shows the transactions in the mempool, waiting to be confirmed?
I'm also wondering why there are so many blocks with just 1 transaction.

How to Pay with Bitcoin With Very Low Fees

If you pay with Bitcoin, and want to pay with very low fees, you can, as long as you time your transaction correctly.
How can you do this? Very simply, the mempool flows between a lot of unconfirmed transactions and very low numbers of transactions waiting in the queue to be processed by the miners.
Time your payment correctly when there are few transactions waiting to be confirmed and you will only have to pay a few cents to get included in the next block!
Alternatively, if your payment does not need to recipient in a hurry, just pay the lowest fee your wallet allows, which is normally 1 sat/byte, and it will confirm in the next trough of low numbers of unconfirmed transactions.
Bitcoin is capable of handling 100s tx/s, when you take layer 2, Lightning transactions into account. Lightning is the best way to do instant transactions for almost free!

HELP ! Unconfirmed Bitcoin Transaction ... 0 confirmation, "STUCK" ... how to recover ?

Here's the story I wanted to transfer all my BTC from Ledger to an exchange (CDC) I never touch fees, I let the Ledger put the best for me, even if it's high, I'm sure around 100% the transaction will go well.
EXCEPT TONIGHT.
Althoug fees around 9 dollars, my BTC are stuck in the blockchain ...
"UNCONFIRMED"
"0 CONFIRMATION"
and it's now hours (maybe 5 hours from now)
I have read this https://coincentral.com/cancel-unconfirmed-bitcoin-transaction/
I don't understand, but the question is : is this trick compatible with Ledger BTC Wallet ?
In other words : is BTC Ledger wallet compatible with RBF ? (WTF is that, seriously ...)
I want to cry right now, because it was all my BTC bought during 3 years, and ... there are in same time somewhere and nowhere, my heart is hard pumping.
Thanks for your help :(

Double-spending unconfirmed transactions is a lot easier than most people realise

Example: tx1 double-spent by tx2
How did I do that? Simple: I took advantage of the fact that not all miners have the exact same mempool policies. In the case of the above two transactions due to the fee drop introduced by 0.9 only a minority of miners actually will accept tx1, which pays 0.1mBTC/KB, even though the network and most wallet software will accept it. (e.g. Android wallet) Equally I could have taken advantage of the fact that some of the hashing power blocks payments to Satoshidice, the "correct horse battery staple" address, OP_RETURN, bare multisig addresses etc.
Fact is, unconfirmed transactions aren't safe. BitUndo has gotten a lot of press lately, but they're just the latest in a long line of ways to double-spend unconfirmed transactions; Bitcoin would be much better off if we stopped trying to make them safe, and focused on implementing technologies with real security like escrow, micropayment channels, off-chain transactions, replace-by-fee scorched earth, etc.
Try it out for yourself: https://github.com/petertodd/replace-by-fee-tools
EDIT: Managed to double-spend with a tx fee valid under the pre v0.9 rules: tx1 double-spent by tx2. The double-spent tx has a few addresseses that are commonly blocked by miners, so it may have been rejected by the miner initially, or they may be using even higher fee rules. Or of course, they've adopted replace-by-fee.

Core Does Not Control Bitcoin. Run a Bitcoin Unlimited Node.

I’ve been told several times by Bitcoin Core developers, specifically Greg Maxwell, but also many others, that they do not “control” Bitcoin. That they merely write the code they want and people can choose to run it or to run something else. “That’s how it works”, they say.
They claim to not be in control, yet they viciously attack other Bitcoin development teams and those supporting them. They also actively Back the bitcoin censorship of any code or ideas not produced by them while allowing attacks and name calling of those opposing their settlement layer direction.
I believe it is this, “we can do whatever we want” attitude that led them to ignore users and businesses in the first place.
We’ve seen transactions approach the blocksize limit for two years. Gavin Andresen wrote elegantly about why we should increase the blocksize in 2015, rather than waiting until it became a problem. Well, Core didn’t listen and now it is a big, big problem.
Some core supporters even have the nerve to say, “a hard fork would take a year to prepare and it’s too late for that now, just run Segwit”.
Expert developers know better. Segwit is a road to a settlement-only Bitcoin: A very narrow sliver of Satoshi’s original vision of peer-to-peer electronic cash that we all signed up for.
Everyone is excited about an ETF, but when that hits later today there will be massive movements either up or down depending on what happens. This is sure to cause excessive fees and new levels of unconfirmed transactions.
Bitcoin Unlimited and Bitcoin Classic are actively listening to users. They’ve solved the blocksize issue once and for all by taking it out of the reference protocol and putting it in the hands of the miners who secure the network. This is safe because miners both want the network to function while also having some revenue from fees. Blocksize increases can happen gradually over time with consensus rather than requiring hard forks every 5 years. It is the best solution moving forward that anyone has proposed.
We have seen that Core cannot be trusted.
We have seen them act negligently towards basic network functionality.
We have seen them ignoring users and only developing for “sexy” second-layer vaporware off-chain projects.
We must do as Greg Maxwell suggested and run something other than core’s code.
We must fight the fear-driven propaganda and biased censorship from bitcoin.
We must call out the minority attacks on the network whether it’s threats from a user-activated soft fork or any other malleability attack
In order for Bitcoin to succeed long-term, we must give control back to the users.

Can we talk about these transaction fees now?

At time of posting, the number of unconfirmed transactions is over 220,000:
https://blockchain.info/unconfirmed-transactions
Bitcoin's current throughput is simply not sustainable and it is scaring the shit out of me. Right now there is a lot of ignorant new money entering bitcoin, with the intention to make quick gains. So while the scaling issue may not be largely impacting the price today, you can bet your bottom-satoshi that shit is going to get ugly soon enough.
What is bitcoin doing for scaling at the moment? What is the roadmap; is this going to be sorted out next week for next year? Let's talk about the future of this technology.

Does Trezor Wallet allow you to create a transaction with unconfirmed bitcoins?

Basically, I want to know if you can easily create a CPFP transaction on the Trezor. For example, you have 10 BTC in one of your Trezor accounts. You send someone 8 and let's say you set a super low fee of 1 sat/byte. The transaction sits unconfirmed for 1 day.
But since you know there is change coming back to you. Can you make another transaction from that account and select to send the 'MAX' amount of bitcoins (hoping the bitcoin in the change address will be included) and this time you set a super high fee so that the miner will pickup both the first low-fee transaction and also the second one?
I know this can be done in theory but I am wondering if the Trezor wallet will even allow you to try to 'spend' the change since it is unconfirmed? In other words, when you select to send 'MAX' on the Trezor will it select only confirmed bitcoins and ignore the BTC that are going into the change address from the previous transaction?
