Topic: [UPDATE: 2015-05-10] Bitcoin Core soft-fork "No Forced TX Fee" v0.10.1 available - page 12. (Read 59262 times)

OK, never mind. I fixed this myself in all branches.
AllowFree() returns correct values now.

----
Ah, one more thing.


Incorrect.

I just looked at the code and it seems that it only protects against people who don't know programming well enough to change it themselves. And hackers & bad guys usually do, or simply pay somebody who knows.
Basically by changing one line of code in the client, you can do whatever you want (and send whatever transactions you want).

So i don't really understand what was the point of forcing everybody to pay the miners additional fees if it wasn't necessary.
Mining cartel of whatever ?

Ideally the fee-setting algorithm will eventually become a plugin so that people can safely and conveniently experiment with different fee strategies.

Come to think of it, the coin selection algorithm would also benefit from being pluggable.

But this is a good interim measure. Thanks!

Just a friendly reminder that the "Satoshi client" is switching from wxWidgets to Qt4 soon, so it may make sense to wait until that is done before putting effort into new dialogs.

I would personally welcome a fork of the "Satoshi client" with other improvements (such as proper URI support), to shake the monopoly the mainline currently holds.

Yeah, i had the same idea that a while ago, but i was either unnoticed or ignored by main devs.

Also, i cannot create a new dialog box myself, because I am not really a C/C++ programmer (and i don't have a proper C/C++ IDE installed at the moment) so i can only do minor changes & code merges at most.
I programmed several languages in my life and I was thinking many times about learning C, but it always was too time consuming and i never had the time.

But if you know how to implement this, you are welcome to do so yourself.

This was default behavior in 0.3.20 and it worked fine for me.
EDIT: Err i checked in the code and actually it wasn't but if you know how to do it better, you are welcome to try.

0.3.21 and later versions has brought me only problems.

I can't even send 10 BTC i received hour earlier, because dialog says it needs a fee.
So i downgrade to 0.3.20 and poof ! Problem fixed. I can resend the money, and later i get 2-3 confirmations after about an hour.

So this is why i said that the algorithm is broken.

IIRC, fee is the only known mechanism to protect against the "penny flooding" attack.

@OT, Didn't someone point that simply returning true has broader impact that just removing the fee?

Welcome for the change. But I think it would be more useful if you can show calculated fee in the send coin dialogue. When the user input the amount, then it should automatically calculate the minimum fee (COIN * 144 / 250) or when the user click the button. The user can freely adjust the fee as they want in the fee input field.

After they click send, it will give them a warning of the consequence of low fee and then asking whether they want to process payment with low fee. It should send out the transaction no mater what fee they enter. It should give a much higher usability improvement.

Many one should be happy for such change so that you may then ask a pull request then.

Warning: Only use this fork if you know what you are doing.
Otherwise, there is a low probability that some coins sent without a fee will be lost stuck in a limbo and difficult to recover.
Read details below.

2013-03-24 WARNING !!
PLEASE NOTE THAT UNTIL MAX BLOCK SIZE PROBLEM HAS BEEN SOLVED BY DEVELOPERS, SOME FREE (WITHOUT FEE) TRANSACTIONS CREATED BY THIS FORK MAY CONFIRM VERY SLOWLY OR NEVER.
YOU HAVE BEEN WARNED, THANK YOU FOR YOUR ATTENTION.




-------------------

Okay, here we go.

So as I promised, I created the "NFTF" (short of No Forced TX Fee) section on Github.
This isn't going to be anything big & professional, just few lines of code changed comparing to the standard client.

I did it, because i was unsatisfied with standard client forcing people to pay fees, even when they are not necessary at all.
I wrote many complaints about this on multiple topics on this forum, and for unknown reasons the main developers do not want either to remove this broken algorithm, or to improve it. Mining cartel ? CIA-related conspiracy ? Who knows & Who cares. I don't know and I don't care so I am going my own way.

So here you are.

Full list of branches & tags is avaiable here:

Branches contain code of older versions (from 0.3.21 to 0.3.24).
Tags contain newer versions, 0.4.0 and up.

----------------

Warning: Use this fork with following precautions (the same as if you would use mainline client v0.3.20 version):

- Make sure you get at least 7 confirmations first when resending the money without a fee.
- Sending small amounts (< 0.01) without any fee may be risky.
- Include a fee when sending money received from a lot of inputs.

2011-09-22 Update:

Today I have merged back the commit from trunk which fixes an unfairly high fees that have to be paid to the miners sometimes due to a bug re-introduced in 0.3.24.

For details see the discussion here:
https://bitcointalksearch.org/topic/bitcoind-transaction-fees-one-annoying-shit-i-have-stumbled-upon-45259

The patch is/will be already present in 0.4x version of official client, but i have also merged it back into 0.3.21, 0.3.22, 0.3.23 and 0.3.24 versions - for people who like to use older and more tested apps.

https://github.com/ShadowOfHarbringer/bitcoin-nftf/commits/nftf-0.3.21
https://github.com/ShadowOfHarbringer/bitcoin-nftf/commits/nftf-0.3.22
https://github.com/ShadowOfHarbringer/bitcoin-nftf/commits/nftf-0.3.23 (that version already contained the patch)
https://github.com/ShadowOfHarbringer/bitcoin-nftf/commits/nftf-0.3.24

If you have used trunk version, it already contained the patch, merged back from official client.
https://github.com/ShadowOfHarbringer/bitcoin-nftf/

Enjoy your no-unnecessary-fee transactions !
As always, wait for at least 7 confirmations before re-sending money so you lower the risk of transaction not being accepted by the network.


----------------
2011-09-24 Update:

NFTF - version 0.4.0 released.

Also:
- Removed all the messy git tags merged previously from the mailine client
- Created new, clean tag for NFTF-0.4.0
- Minor cosmetic changes in comments

So from now on, code will be organized in tags, not versions - as it should be from the beginning.

0.4.0 code is avaiable in the tag:
https://github.com/ShadowOfHarbringer/bitcoin-nftf/tree/nftf-v0.4.0/

And trunk code is avaiable from the trunk, as always. I usually only update it on major version changes or important features/bugfixes, so don't expect me to keep up with mainstream client developers all the time.

Trunk: https://github.com/ShadowOfHarbringer/bitcoin-nftf/tree/

Also, i have performed few tests, sending back and forth small amounts of BTC (0.01) having only 2 confirmations, and it seems that my fork is stable enough for the payments to get confirmed easily (up to 2 hours) without using any fees.
