That is a completely different transaction ID to the ones you had earlier?!?? Did you send this transaction? If so, the fee is very low at ~50 sats/byte... but you can still try the ViaBTC TX Accelerator.

miners have to process every transactions
Actually, they don't... there is no "rule" or obligation that says miner have to include any given transaction in a block... ever. They are free to mine empty blocks if they want and just claim the block reward. That's why you pay a fee... to entice the miner to put your transaction in a block. IMAO all the honest and good mining pools should provide a service similar to this one but each pool with at least 1000 transactions per hour, then after solving the captcha you manually submit your TX.
Given that the average number of transactions going into blocks at the moment is somewhere around 2000, you think miners should have to hand over half of the space available in a block to bitcoin users who are too cheap to pay the proper fees? Have you heard of supply and demand? When Supply is low (1 meg blocks) and Demand is High (110 megs of unconfirmed transactions)... prices go up. Welcome to the "free market"

The words are definitely correct, with spacing and capitals where appropriate.
None of the wallet words should have Uppercase characters... they should all be lowercase. Chances are tho, if you've been hit with the "Password did not unlock the wallet" issue, even if you restore from your wallet words, you'll get the same problem over and over... the issue is fairly well known around here... and the devs know about it: https://github.com/keepkey/multibit-hd/issues/982If you can, I'd recommend switching to a new wallet... if you have an iOS or a relatively new (Marshmallow+) Android device, you can get access to your coins by restoring your wallet words using "Breadwallet" app... There is also "Simple Bitcoin Wallet" for older Androids (from version 4.0.3+). And you can send your coins from there to a new wallet of your choosing... I wouldn't recommend staying with either Breadwallet or Simple Bitcoin Wallet as long term solutions. If you don't have access to an iOS or Android device... there are other ways to get your coins out. I have some python scripts that can extract the private keys from the wallet that have your unspent coins and you can import them to another wallet... or you can do it yourself by putting your wallet words into an offline copy of https://iancoleman.github.io/bip39/ then goto Derivation Path, select BIP32 and then set client to custom and the path to m/0'/0 and then look through all your addresses for coins (you may need to click "show more"), noting down the private keys for addresses with coins. Then set the path to m/0'/1 and look through all your change addresses for coins, noting down the private keys for addresses with coins. Then you can import the keys to another wallet. Good luck.

So how would you be able to tell how much coin you can actually spend? or what you have spent? I don't understand why anyone would want this... it makes no sense.

Sir, how do you understand these levels? The accelerator does not allow to enter the TX, I will wait until tomorrow, the main thing has been confirmed.
Have a look here: https://btc.com/stats/unconfirmed-txFind your fee on the left... on the right you can see the running total amount of bytes at each level under "Size Count" column. Roughly every ~1,000,000 bytes is one block worth of transactions. So, if at your level it says "3,771,244" bytes, then there is just under 4 blocks of transaction at or above your fee level. EDIT: Oh hey... your transaction has been confirmed! YAY!

And now all you have done is create another transaction in the unconfirmed chain, with a low fee... your new transaction only has a fee of 50 sats/byte... the recommended fees at the moment are more like 300 sats/byte. I did warn you to be careful. Plus, because this transaction is spending from an unconfirmed parent, which is spending from an unconfirmed parent... it is not going to confirm for a looooooong time. And you can't try and use the ViaBTC accelerator because it has unconfirmed parent transactions. If you were intending to do a "Child Pays For Parent" transaction, as opposed to a double spend... then you should have used a fee that would have resulted in an average fee across all three transactions being around 300-350 sats/byte... ie. 225 bytes + 226 bytes + 225 bytes * 350 sats = 237300 sats (or 0.00237300 btc). You used 11300 sats or 0.000113 btc. If you're going to continue using Electrum, I highly recommend you go into "Tools -> Preferences -> Fees" and make sure Dynamic Fees is checked.

And you are sure that the IDs of those 2 transactions are definitely: b610d290a43e973ba9bd021ff5d3029491accb01c5f4ec8f0c16286e945dc169 and 6b440075c82470e8a2af90e62688ff0812429190232b1d15e7bdf652b51d8110 If so, then I can only assume that the Electrum server you are connecting to, still has your transactions in it's mempool... so it is sending it back to you when you recreated your wallet.

Your last transaction has a 240 sats/byte fee... there is currently around the 8 blocks worth of transactions above that level... if you're lucky, it might get confirmed in the next 24 hours by doing nothing. It is hard to predict exactly what is going to happen... Give the ViaBTC accelerator a go... but I wouldn't stress too much

Isn't this a very similar number of bytes for each transaction? I mean, it's simply adding or removing numbers for public addresses - isn't it?
Not necessarily. When you send bitcoins to an address... it creates an "Unspent Transaction Output"... also know as an UTXO. When you want to create a transaction, you need to start adding UTXOs together until you get enough to add up to the total you're trying to spend (+ miners fee). So... if you have a "big" UTXO, like 1.0 BTC... and you want to send 0.1 BTC someone... that's easy... 1 UTXO in -> 2 UTXOs out (0.1 to the person, 0.8999 back to you as change, + 0.0001 miners fee). A transaction like that (1 in, 2 out) will generally be around 226bytes. However, if you have a whole bunch on little UTXOs in your wallet... like you have 15x 0.01 BTC payments... and now you want to send 0.1 BTC to someone... you're going to need 11 UTXOs as input (remember, you have to cover the miners fee!) So... 11 UTXO in -> 2 UTXO out (0.1 to person, 0.009 to you as change + 0.001 miners fee). The "general" formula for transaction size is: (#Inputs * 148) + (#outputs * 34) + 10 bytes So, the first one: (1 * 148) + (2 * 34) + 10 = 226 bytes and the 2nd one: (11 * 148) + (2 * 34) + 10 = 1706 bytes! This is the reason why you should try as hard as possible to avoid collecting lots of small amounts in your wallet... sooner or later you'll end up needing to use a whole bunch of UTXOs to create a transaction and you'll get slammed on fees Another question in that path: Once I send something bitcoins, where does my transaction goes to for all the miners to grab it from? I understand that all the past data is in the blockchain, but where is the data that is still not in the blockchain?
There is a network of "nodes" who hold and relay unconfirmed transactions... they have what is referred to as a "mempool" or memory pool... your transaction sits in the mempool of various nodes until a miner includes it in a block. If it sits for too long (used to be around 72 hours, but seems to be getting longer these days) nodes will start to drop it from their mempool. Once all nodes drop it, it is like the transaction never existed and your coins should be respendable by your wallet.

Note: You won't be able to do the "Double Spend" from Electrum. It won't (shouldn't) let you... and is quite likely to just spend "different" coins.
Be very careful with Double Spending and make sure you understand exactly what it is you're attempting to do and how to go about doing it. Otherwise, you'll just make things worse.

Bitcoin / Bitcoin Technical Support / Re: Does sending BTC from 3 wallet address roughly triple the transaction size?
|
on: May 25, 2017, 04:58:20 AM

Transaction size in bytes is calculated more or less as:
(#Inputs * 148) + (#outputs * 34) + 10 bytes.
It isn't the number of addresses per se, but the number of inputs... For example, I've seen transactions that have 10 inputs... all from 1 address... but it is still 10 inputs... so 10 * 148 = 1480 bytes, + the output bytes + the 10 fixed bytes...
Also, when you send multiple inputs to an address... it doesn't create one big amount of BTC... they are all still separate chunks...
ie. if you send 1.0 BTC, 0.1 BTC and 0.01 BTC... you don't have a single amount of 1.11 BTC in your wallet... you still have 3 separate UTXOs that you can then spend.

I've had MultiBit HD do something similiar... where it won't activate the "next" button for some reason... I usually just click "previous", reselect that i want to restore and try typing the 12 words in again (NOTE: don't try and copy/paste it in either). You can also double check your 12 words here: (NOTE: Run an offline copy to be safe!) https://iancoleman.github.io/bip39/It even offers suggestions for mispelled words

Who cares what time it is at bitcointalk? Last time I checked, most places in the world are on "whole hour" timezones offset... so +1 UTC, -5 UTC, +12 UTC etc... so it really makes no difference where in the world you are... Just do it at the start of the hour. The only places that use something different are "North Korea, Newfoundland, India, Iran, Afghanistan, Burma, Sri Lanka, the Marquesas"... if you happen to be on a X.5 hr timezone (Like India at +5.5)... then you need to submit at XX:30:00 at your location.

Then you are submitting it too late... you have to submit in like the first 1 minute of a new hour... any later than that and the 100 slots will be full... seriously, sit and watch the clock tick over to XX:00:00 hrs... and click submit
