Bitcoin Unlimited how to delete unconfirmed wallet transactions without rescan

So due to a mistake on my part while splitting my BCH and BTC, all my backups of my BCH wallet.dat file have unconfirmed transactions that are on the BTC blockchain. I downloaded the BCH blockchain using Bitcoin Unlimited in prune mode because storage is tight. I assumed that when it got past the BTC transactions it would simply delete them (they're the wrong transaction format and not in any block) but it hasn't.
All the methods of deleting transactions from wallets rely on using -zapwallettxes and -rescan, which I would rather not do (it took quite a while to download the blockchain to begin with).
Is there any way to delete those transactions from the wallet file without a rescan?
Note - the blockchain still has 10 days left to download, but the transactions are older than that.

Unconfirmed transaction locally deleted in mycelium: did i just kill my bitcoin?

hey guys, happy new year. today i had some beers with friends and the mixed alcohol and bitcoin. i've had an unconfirmed tx in the mempool for about a week, and decided to try to cpfp (mycelium) but it didn't work, so i deleted the transaction locally. now on my mycelium wallet i see 0 balance and in the blockchain.info i have an unconfirmed tx that will likely stay there indefinitely. does the tx eventually expire in the mempool and get back in my wallet. i'd rather not lose all i have. fuck that was dumb. please help

I’m just wondering this assuming I own a hardware wallet (ledger per say) if I were to send a transaction of 1 btc to a different address while it’s being confirmed do I still technically have that bitcoin? If not where is it? Cause it’s not at the other persons wallet yet?. Assuming my knowledge is correct, you just shared the control of a specific bit of satoshis. So that means I own it until transaction is verified?

"My transaction is stuck, what to do?" - an explainer [DRAFT]

In the last days we have been experiencing a sharp rise in price, which is historically correlated with many people transacting over the Bitcoin network. Many people transacting over the Bitcoin network implies that the blockspace is in popular demand, meaning that when you send a transaction, it has to compete with other transactions for the inclusion in one of the blocks in the future. Miners are motivated by profits and transactions that pay more than other transactions are preferred when mining a new block. Although the network is working as intended (blockspace is a scarce good, subject to supply/demand dynamics, regulated purely by fees), people who are unfamiliar with it might feel worried that their transaction is “stuck” or otherwise somehow lost or “in limbo”. This post attempts to explain how the mempool works, how to optimize fees and that one does not need to worry about their funds.

TL;DR: Your funds are safe. Just be patient* and it'll be confirmed at some point. A transaction either will be confirmed or it never leaves your wallet, so there is nothing to worry about in regards to the safety of your coins.

You can see how the mempool "ebbs and flows", and lower fee tx's get confirmed in the "ebb" times (weekends, nights): https://jochen-hoenicke.de/queue/#0,30d
* if you are in hurry there are things like RBF (Replace By Fee) and CPFC (Child Pays For Parent), which you can use to boost your transaction fees; you will need an advanced wallet like Bitcoin Core or Electrum for that though. Keep also in mind that this is not possible with any transaction (RBF requires opt in before sending, f.ex). If nothing else works and your transaction really needs a soon confirmation, you can try and contact a mining pool to ask them if they would include your transaction. Some mining pools even offer a web-interface for this: 1, 2.
Here’s how Andreas Antonopoulos describes it:
In bitcoin there is no "in transit". Transactions are atomic meaning they either happen all at once or don't happen at all. There is no situation where they "leave" one wallet and are not simultaneously and instantaneously in the destination address. Either the transaction happened or it didn't. The only time you can't see the funds is if your wallet is hiding them because it is tracking a pending transaction and doesn't want you to try and spend funds that are already being spent in another transaction. It doesn't mean the money is in limbo, it's just your wallet waiting to see the outcome. If that is the case, you just wait. Eventually the transaction will either happen or will be deleted by the network.
tl;dr: your funds are safe

How is the speed of confirmations determined in bitcoin?

Open this site: https://jochen-hoenicke.de/queue/#0,2w
Here you see how many transactions are currently (and were historically) waiting to be confirmed, i.e how many transactions are currently competing with your transaction for blockspace (=confirmation).
You can see two important things: the differently coloured layers, each layer representing a different fee (higher layer = higher fees). You can point at a layer and see which fees (expressed in sat/byte) are represented in this layer. You can then deduct which layer your own transaction is currently at, and how far away from the top your position is (miners work through the mempool always from the top, simply because the tx's on top pay them more). You can estimate that each newly mined block removes roughly 1.xMB from the top (see the third graph which shows the mempool size in MB). On average, a new block is produced every ten minutes. But keep in mind that over time more transactions come into the mempool, so there can be periods where transactions are coming faster than transactions being “processed” by miners.
The second important observation is that the mempool "ebbs and flows", so even the lower paid transactions are periodically being confirmed at some point.
In short: what determines the speed of a confirmation is A) how high you set the fees (in sat/byte), B) how many other transactions with same or higher fees are currently competing with yours and C) how many transactions with higher paid fees will be broadcast after yours.
A) you can influence directly, B) you can observe in real time, but C) is difficult to predict. So it's always a little tricky to tell when the first confirmation happens if you set your fees low. But it's quite certain that at some point even the cheap transactions will come through.

So what happens if my transaction stays unconfirmed for days or even weeks?

Transactions are being broadcast by the full nodes on the network. Each node can adjust their settings for how long they keep unconfirmed transactions in their mempool. That’s why there is not a fixed amount of time after which a transaction is dropped from the mempool, but most nodes drop unconfirmed tx’s after two weeks [IS THIS CORRECT?]. This means that in the absolute worst case the unconfirmed transaction will simply disappear from the network, as if it never happened. Keep in mind that in those two weeks the coins never actually leave your wallet. It’s just that your wallet doesn’t show them as “available”, but you still have options like RBF and CPFP to get your transaction confirmed with higher fees, or to “cancel” your transaction by spending the same coins onto another address with a higher fee.

Helpful tools to estimate fees for future transactions:

Here are some resources that can help you estimate fees when sending a bitcoin transaction, so you don't end up overpaying (or underpaying) unnecessarily. Keep in mind that in order to take advantage of this, you need a proper bitcoin wallet which allows for custom fee setting. A selection of such wallets you can find here or here.
The order here is roughly from advanced to easy.
1) https://jochen-hoenicke.de/queue/#0,24h
Here you can see a visualization of how many unconfirmed transactions are currently on the network, as well as how many were there in the past. Each coloured layer represents a different fee amount. F.ex the deep blue (lowest layer) are the 1sat/byte transactions, slightly brighter level above are the 2sat/byte transactions and so on.
The most interesting graph is the third one, which shows you the size of the current mempool in MB and the amount of transactions with different fee levels, which would compete with your transaction if you were to send it right now. This should help you estimating how high you need to set the fee (in sat/byte) in order to have it confirmed "soon". But this also should help you to see that even the 1sat/byte transactions get confirmed very regularly, especially on weekends and in the night periods, and that the spikes in the mempool are always temporary. For that you can switch to higher timeframes in the upper right corner, f.ex here is a 30 days view: https://jochen-hoenicke.de/queue/#0,30d. You clearly can see that the mempool is cyclical and you can set a very low fee if you are not in hurry.
2) https://mempool.space
This is also an overview of the current mempool status, although less visual than the previous one. It shows you some important stats, like the mempool size, some basic stats of the recent blocks (tx fees, size etc). Most importantly, it makes a projection of how large you need to set your fees in sat/byte if you want your transaction to be included in the next block, or within the next two/three/four blocks. You can see this projection in the left upper corner (the blocks coloured in brown).
3) https://whatthefee.io
This is a simple estimation tool. It shows you the likelihood (in %) of a particular fee size (in sat/byte) to be confirmed within a particular timeframe (measured in hours). It is very simple to use, but the disadvantage is that it shows you estimates only for the next 24 hours. You probably will overpay by this method if your transaction is less time sensitive than that.
4) https://twitter.com/CoreFeeHelper
This is a very simple bot that tweets out fees projections every hour or so. It tells you how you need to set the fees in order to be confirmed within 1hou6hours/12hours/1day/3days/1week. Very simple to use.
Hopefully one of these tools will help you save fees for your next bitcoin transaction. Or at least help you understand that even with a very low fee setting your transaction will be confirmed sooner or later. Furthermore, I hope it makes you understand how important it is to use a wallet that allows you to set your own fees.

Failed transaction from 10 days ago ... re-broadcast?

I understand the mempool is jammed and transaction fees are up.
About 10 days ago I tried to self-transfer bitcoin from a hot wallet (wasabi) to hardware (using electrum). I used 1 sat/byte fee. At the time the fees had just started rising and I was ok waiting several days/weeks for it to confirm. For the first week, I could see the unconfirmed tx in both wallets.
Yesterday I noticed that wasabi put the funds back into my wallet, and the transaction was deleted from my history completely. I still see the unconfirmed inbound tx in electrum, but it says "Local". Both wallets are pointed at my own Node.
Since electrum saw the inbound transaction, is there any way to push this tx through? It seems like in wasabi I can "double spend" these funds.

How secure is bitcoin from inflation attack?

I just found out that in 2010 BTC was hacked and inflated with 92 bilion BTC. Is this true ?
submitted by cenourinha123 to Bitcoin [link] [comments]


I am starting to lose my patience. I am quite sure ALL of us know how bitcoin transaction works, and know that a VAILD TXID will be produced when a bitcoin transaction is made. UNCONFIRMED transaction WILL BE SHOWN in the BLOCKCHAIN. But I can't find my transaction on the network. ITS NOT IN THE MEMPOOL. MEANING the BITCOINS ARE STILL WITH YOU. STOP LYING FFS.
http://prntscr.com/h9u7vp (screenshot from support chat)
here is the video showing that the transaction is not sent to the network or dropped from mempool and needs to be resend.
I am sure I am not the only one. There are many people having the same problem. And Purse.io is giving them the same replies thinking we are idiots. So before this issue is solved for every poor soul out there. I suggest people cancel all buy orders and get their money out before its too late or another wallet "maintainence" happened. Or purse got hacked and stuff....

Almost 48 hours and no confirmation yet. Are my bitcoins lost forever?

I've sent a tx 2 days ago and it STILL hasn't been confirmed. What happens in this scenario? Do my bitcoins go back to my wallet? Can't I rebroadcast the transaction?
EDIT: It's a shame stuff like this is happening when bitcoin was supposed to be the "instant payment, low fee" solution to fiat money.
EDIT 2: It seems like it has already been rejected
Transaction rejected by our node. Reason: Transaction was previously accepted but has been pruned from our database.
EDIT 3: I opened my wallet and it automatically rebroadcasted the tx. It got confirmed within an hour now, same fee.

Bitcoin core - unconfirmed transaction

Last week I posted here about making a transaction from my Bitcoin Core wallet even though the network is over 3 years out of sync, see my post here. Appreciate the advice that I didn't need to wait for the network to fully sync before making the transaction.
I sent the remaining coins to my LBC account, but after 48 hours it still remains unconfirmed. I'm aware these transactions can take a while (says up to 14 days on the LBC website) but I've researched a little bit about unconfirmed transactions and seems it's relatively common.
I'll give it some more time, but if it remains unconfirmed is there anything I can do? I've read on this post that you can "Run bitcoin core with -zapwallettxes -rescan flags" but the unconfirmed transaction will not be gone until the blockchain fully loads. As mentioned mine is out of sync by over 3 years and I don't think my shitty laptop will be able to download all of that, so is there any alternative option? Or have I misunderstood this slightly?
Appreciate any help
edit - forgot to mention I had not included a transaction fee, I didn't recall having to manually input that with transactions in the past (haven't used it in a few years), I wonder whether this is the reason it remains unconfirmed?

Do Bitcoin transactions ever expire?

Transaction expiration is a common myth/misconception. Once a Bitcoin transaction is created, it never automatically expires. In theory, a transaction could be created, get stuck at 0 confirmations for some years, and then all of a sudden confirm.
Several wallets have the behavior of deleting outgoing transactions from their transaction list after a few days of being unconfirmed. This is insane, and could lead to losses. Consider the following example
  1. You send a transaction. It gets stuck due to having a too-low fee.
  2. Your wallet deletes the transaction after a number of days.
  3. You still want to send the transaction, so you create a new transaction with the same value but a higher fee. This confirms.
  4. The recipient uses child-pays-for-parent (CPFP) to get the first transaction to also confirm. You have now paid twice, losing BTC, even though the first transaction "expired".
It is possible to create two transactions that are mutually exclusive. For example, the proper way of increasing the fee in the above example would be to send another transaction that uses exactly the same coins as the first transaction. Since a single coin can't be spent more than once, only one of the transactions will ever confirm. Actual losses due to the insane expiration behavior of certain wallets are rare because wallets often accidentally use the same coins when recreating an "expired" transaction, but it is very reckless to rely on this.
This myth may have been started by Bitcoin Core's default behavior of removing transactions from its memory pool after 72 hours (later changed to 2 weeks). Due to this behavior, it became likely in most cases that a transaction would never confirm after it went 72 hours unconfirmed. However, just because most nodes will forget about a transaction doesn't mean that everyone must or will do so. You have to plan for the worst case, not the typical case.
