We should be able to add fees after the transaction

[VolanicEruptor]

This would be good for everybody if it was possible.  You make a transaction, only to realize "oh shit, my transaction fee was too low".
Wouldn't it be nice if you could add the fee afterwards?  This way you could push your transaction through faster and give it higher priority.  I bet if this were possible, transaction fees would instantly double just from people being impatient.  Miners would be very happy..

Unfortunately with the way bitcoin works, this seems impossible to actually implement.

But it would be too hard to implement. You will have to edit existing transaction during time of waiting for confirmations...

Just add some more fee while sending at first and that's it.
And no change needed

[odolvlobo]

You can already do that. Send the transaction again using the the same outputs and add a bigger fee. One of them will be confirmed and the other will be rejected as a double-spend.

This is assuming you have 2x the amount to begin with.  If 1x is all you have, you won't be able to send the transaction again.

Please show me link to time machine.  How do I do this..
If I came in here with an idea for bandaids, you would be the first idiot to jump in and say "well dont get hurt in the first place and you wont ever need one!"..

i am using multibit to send BTC
they always give proper fee for transaction, never happen too low fee conditions
but when i use blockchain and custom send, i usually give too low fee, making it slow confirmation by the network

You can already do that. Send the transaction again using the the same outputs and add a bigger fee. One of them will be confirmed and the other will be rejected as a double-spend.

never try something like this
i wanna try send to my own BTC to test

Wrong.

Read again, it says "send the transaction again using the the same outputs".

If a transaction isn't confirmed (yet), no coins have been sent,
if no coins have been sent, you don't need 2x the amount to begin with, 1x is enough. 

[VolanicEruptor]

The transaction can be unconfirmed but still show up on most of the network, in which case the client wont let you send the same amount again.  No?

[grifferz]

if no coins have been sent, you don't need 2x the amount to begin with, 1x is enough. 

Of course you probably need access to some sort of debug console for your wallet to send a raw transaction to do this, but then again, you probably needed to do something out of the ordinary to send a transaction with not enough fees to begin with.

IMHO the wallet should prevent you from doing that in its default user interface and only allow something like that in a more advanced / debug mode.

[VolanicEruptor]

Wrong.

And what's with people who respond with "Wrong" as a stand alone sentence. Is this a game show?   Do I get to try again??

[DobZombie]

It would be GREAT to just have a button under TRANSACTIONS that would allow the addition of a fee.

or even another tab called FEES. Under this you could input the transaction number so you could add a fee after the fact.

This transaction wouldn't have to be a transaction of our own even!

How many time have you guys been expecting a transaction that never arrives ( or takes days?) Wouldn't it be great if you could add a fee to make it quicker?

I know a lot of people whinge about this sorta thing, but couldn't we just do it?  I mean if we can waste code on transaction mailability, why can't we make something useful like this happen?

Also, in before "why don't you do it yourself, bitcoin is open source blah blah blah"
I can't code for shit

blocks are only on average 10% filled. we should NOT be changing the protocol to feed greedy miners.

they are already denying transactions to force fee's. we should STOP that practice.

miners jobs are to process transactions. the REWARD is their wage. miners should not deny transactions because that should NOT be their job, and they should definitely NOT be given a bonus ( a fee ) as a prize for their practices.

Yes this i believe is true.

This is pretty much the only response so far that sounds intelligent.
I agree 100%.  It's like a waiter/waitress refusing to serve you because you are a bad tipper.  This would be okay, except
that this isn't the food industry.  Transactions should all have equal priority.

It's capitalism at work.

If bitcoin actually grew big, you can bet your ass there'd be visa/mastercards of the bitcoin world charging a % transaction fee or they'll reject it.

Miners jobs are to make money for themselves. Nobody invested millions into mining hardware to process transactions for free for other people. Get your facts straight. I understand you're one of the delusional ones who doesn't see the realities of the world, but this is it.

Maybe all future blocks should meet the following conditions ( as well as current protocols) to be a valid block...
if there are >250kb worth of unconfirmed transactions
    then block size must (roughly) equal 250kb

it's as simple as that. Why aren't we enforcing that? The miner's fee was meant to reward miners once the network got really popular and busy.
As opposed to the miners sending small blocks so they get in there first with the valid block.

The block reward is what miners get paid to process transactions.  fees are just icing on the cake.

How could you possibly say that it would miners would be doing this "for free"?  Most of their profit comes from the block rewards, not the fees.

You can easily fill up a block with 250 KB worth of your own transactions rather then accept feeless transactions from other people.

A lot of people are also making assumptions that may apply if mining is decentralized, but fact is, there's 4 major players who control the majority of the hash power of the network.

Yes, and to claim the block reward you don't need to include any transactions. Including feeless transactions is working for free.

Mine on a pool that supports the fee structure you like.  There are pools that allow more free transactions and ones that allow less.

The point of fees is to reduce transaction SPAM.  It does work as intended and (non required) fees are now well under 1/10 of one percent for most transactions.  

[FeedbackLoop]

Do take into consideration that space itself in the blockchain is also a limited resource and fees contribute to keep it civil while storage and bandwidth catch up. Miners have an incentive to keep block size sane as big blocks have a higher chance of being orphaned.

Make sure to re-use the same outputs when resending that transaction with fees otherwise the old tx might get confirmed later and then you sent double the amount. (I don't know how as I never ended up in that situation :p).
