Shares are (supposed to be) recorded as their value at the time they were found - but that value needs to be measured in fraction-of-block-reward. That means every 4 years, it effectively halves like the rest of Bitcoin.

I didn't expect there to be any argument with this, so I just told wizkid057 to go ahead with fixing it before we accidentally overpaid any more (IIRC, there was 2-5 BTC overpaid at the time we noticed the problem). In theory, it's also in theory easier to reverse this fix, than it would be to fix it later after having overpaid shares. If there's a concern this might not be the right decision, we should have time to discuss it (I suggest a dedicated thread started by someone opposed to the fix).

Seeding, if you can get to me.
Thanks!

Could you redo a new torrent with pruned index up to block 210000 (checkpoint)? A torrent with only 39% of the blockchain is becoming less useful to get new users started.
These only work because they're right at 2 GB boundaries. blk0002 might be possible if I get the time...

FWIW, I just came across a remote buffer overflow exploit in both cgminer and BFGMiner. It's unlikely that it can be used for anything other than a pool crashing the miner program, and I will have it fixed in the next BFGMiner release. Just in case (I'm no security expert), details are only available privately to persons with a good reason to know (like Con) until the fix is released.

Protecting the network is very easy: don't include non-standard transactions in blocks.
An attack like this just requires a hostile party to mine 1 block.
That's still within reach of most people, even after ASIC hits on full.
Blocking out "non-standard" transactions in general just harms potential innovation.
2526  Bitcoin / Development & Technical Discussion / Re: New Bitcoin vulnerability: A transaction that takes at least 3 minutes to verify on: January 31, 2013, 11:00:39 PM
And since this attack requires non-standard transactions, mining a block is the only way an attacker will be able to pull off this attack.

There is at least one mining pool that accepts direct connections to be used to send non-standard transactions. So the attack could in theory be done by anyone willing to pay some fees (that, right now, are very cheap).
I presume you're referring to Eligius here. We can just disable non-standard transactions until I come up with a good long-term solution...

Wouldn't this also be fixed by simply caching the transaction hash for the first OP_CHECKSIG ?
2527  Bitcoin / Mining software (miners) / Re: FPGA project assistance with old source code on: January 31, 2013, 03:36:30 PM
Reading anything luke-jr has to say just aggravates me because of many of his claims, including things like saying cgminer is "deprecated" while it is clearly still being actively maintained, and writing that it has some kind of substandard FPGA support when he ends up copying code from cgminer's FPGA code implementation.
cgminer is pretty much deprecated - as a GPU miner, in a world that has moved on from GPUs. cgminer's FPGA code, which came from and was maintained mostly by myself until you cut it off from its main development branch, is horribly outdated and mostly only grown worse as Kano incompetently tried to "improve" it - so your choice of "substandard" here is pretty accurate!
ROFL didn't you just say a few days ago that the GPU code in CGMiner and BFGminer are almost exactly the same? So why are you calling his GPU code "deprecated" and your isn't? And as much as you don't like Kano, or you don't like the changes he's making to FGPA, USB, or ASIC code, you simply just can't call his software "deprecated" if it's still being actively maintained and worked on.
I'm calling GPU mining in general deprecated. BFGMiner had FPGAs as the focus from the start; OpenCL support is there mainly because it doesn't hurt anything. BFGMiner also supports CPU mining. Both CPU and GPU mining are deprecated.

i hate ppl who do lie
It's not healthy to hate yourself.

BTW, I don't lie.

To a casual observer, many of your posts appear to be more than a little bit misleading. If your statement is true (considering that, statistically, liars say it more often), then it is so only by technicality.
Care to elaborate? While I don't hestitate to put mental reservation into use for good reason (such as keeping others' secrets) and sometimes leave out technical details that are irrelevant and I cannot easily explain to the audience, and sometimes I may even be mistaken, nothing I say is known by me to be false at the time.



The "reason" luke-jr created the fork to cgminer was that he contributed code to cgminer that was rejected by me based on evidence provided by Kanoi that it was buggy, but he just wanted the code out despite the issues with the code which I refused to accept as the concerns were valid.
Really? What evidence was that? When did you ever show any interest in FPGAs before you got upset over the ASIC announcement, for that matter?

No, you intentionally-blindly accepted Kano's revert of all the improvements and bugfixes I had made to the Icarus driver on Kano's whim.
Furthermore, the Windows compatibility Kano pointed out was broken, was not ignored, but easily fixed without reverting any of the improvements or bugfixes.
Do you junk your new car just because someone finds one of the fuses is popped, or do you just fix the problem and move forward?

One unfortunate thing is that the git source control management system tells you who committed code to a source tree (such as bfgminer), but not who actually wrote the code. Follow the parent of the code tree on github on bfgminer and you'll see it was basically mostly code pulled from cgminer that I and kanoi have written.
No, git handles attribution just fine - when used correctly. While you and Kano regularly misattribute your commits based on code from others, I make good use of the --author option to give credit to the person who wrote the code.
Considering you've claimed you never look at BFGMiner code, it's ironic you claim it's mostly code pulled from cgminer. I encourage anyone who knows his way around git (even github's web interface isn't too bad) and has any doubts about this, to look at the code themselves and see plainly where BFGMiner code came from or didn't.

I even went to the extent of developing my own GBT implementation, which is the communication protocol invented by luke-jr (that I dislike immensely compared to stratum) from scratch rather than use his already existing "reference implementation" because his code was python and it would be more efficient coded by myself in c instead.
That's called the not-invented-here syndrome. Also, libblkmaker is and always has been standard C.

Whenever questioned about something he either simply says "it's not true" or "I don't lie" or doesn't respond, or appeals to a forum moderator to have the post deleted as a troll.
No, that's how I handle trolls and claims with no basis in the truth (usually repeated from a troll). These are pretty standard recommended ways of dealing with trolls.
That I let any posts like this one of yours trick me into wasting time responding, I guess is my own fault.

He has also never been known to back down on an argument, say he's wrong or accept any form of leadership, constantly trying to take charge - so far as leading to a huge battle between the lead bitcoin maintainer, Gavin Andresen, and himself on one of the BIP issues.
While I don't generally abandon functionality I need (or else I wouldn't have taken the time to write it in the frist place!), I regularly act to make them more compatible with others' objections. It's not unheard of for others to convince me that I'm wrong either, though that takes actual logic, not mere trolling like you and Kano enjoy doing. Even while BIP 16 is the P2SH solution adopted by Bitcoin, it doesn't take a rocket scientist to see that BIP 17 was the superior solution - but that's all ancient history now.

Reading anything luke-jr has to say just aggravates me because of many of his claims, including things like saying cgminer is "deprecated" while it is clearly still being actively maintained, and writing that it has some kind of substandard FPGA support when he ends up copying code from cgminer's FPGA code implementation.

I have observed very strange behavior of some miners using BFGminer 2.10.2. When new block is solved by network pool creates new block template and emits it to all subscribed miners using mining.notify rpc.

The issue is: very often those BFGminer miners keep submitting shares for previous block (stales) for quite a long time (several seconds)

In example below Client 52 asks for transactions after he received mining.notify number 946, and almost 3 seconds later submits work belonging to previous block (945). 2 sec later the same situation occurs.
I'm sure that miner received mining.notify 946 message because 150ms later he asks for transactions for block template 946

Can you please look into it?
Can you provide a test stratum URI that I can reproduce this with?
2530  Bitcoin / Hardware / Re: [Announcement] Avalon ASIC Ships on: January 29, 2013, 01:02:44 PM
It was interesting to see in the #btcfpga IRC channel, Luke-Jr saying he had images of the inside of the Avalon.

So any customers hoping to see them - I guess that a complete - "fuck you" from Avalon.
They don't give a shit ... ... ... or they still haven't got the software working and wanted Luke-Jr's help.
I wonder which it is?
Slander, did not send Luke any photos, nor we asked him for help.
FWIW, as BitSyncom said, they didn't send me any photos nor ask for any help. Not sure why kano feels the need to make these speculations.

One that auto-swaps coins with strangers in IRC using this very same flow you've got going here.
I've actually done this manually a few times with a few different people— well, IRC messages are too short for most transactions. Sad but encrypted pastebins work.  I thought it would be fun to get more people involved.

Why bother encrypting it?

Was wondering if anyone had tried eloipool on a windows server?
"Windows" and "server" don't go together. And no, it won't work on Windows. You could possibly port it to use select(), but that's going to run into scaling problems very quickly. Too bad Windows doesn't have any sane socket polling interface - but I guess that's why it isn't a server platform.

Also, which version of the bitcoind is recommended for the best performance.
Eligius and I think some others are running my 0.6.0.eligius branch, based on 0.6.0.x (but does have even better GBT support than mainline).

2534  Bitcoin / Bitcoin Discussion / Re: SERIOUS VULNERABILITY related to accepting zero-confirmation transactions on: January 26, 2013, 09:10:36 PM
I have a requirement that isn't satisfied on the 0.8 series, an effect of the leveldb implementation. I need to be able to read raw tx for non wallet transactions, and these are no longer kept, so for now I can't update.
This will be fixed in 0.8 (though require you to use a new option the first time you start it).

Can someone please post what are the BTC addresses accepted for each ASIC company?

I was looking through one of bASIC's addresses and it shows they only took in 541,000 USD (in BTC).

What are the addresses for BFL and Avalon?
That's not how Bitcoin works.

You should upgrade it to BFGMiner, which is focussed on FPGA/ASIC mining (cgminer's FPGA support originally came from this).

MPBM simply ignores the non working FPGA and runs with the resuming FPGA, can bfgminer do the same ?
Looks doable. Let me see if I can figure out a way to reproduce the crash here...

So... Will there be x6500 support.. or not ?! Smiley
You heard them, they don't want to copy and more updates to the FPGA code because they think not doing so now helps their case for pretending it never happened.

Any chance we can see x6500 support in cgminer ?

I really dont want to use rip-off-scumbag-bfgminer just because of this..
I'm currently running them on MPBM but I'm not happy with it.

You have things backward: cgminer is trying to rip off BFGMiner.
From January until the middle of May (2012), I was the only one who had anything to do with device driver or FPGA support, with exception to Xiangfu who contributed a complete Icarus driver (based on my BitForce driver) in Feburary (which I maintained afterward). While Con was copying these improvements back into cgminer, I had no reason to make a separate release under another name - obviously a mistake that in hindsight has allowed Con & Kano to steal credit for it. It wasn't until April that Kano decided to begin forking the code (in the process reverting numerous bugfixes and improvements since he doesn't know how to use git), and Con backed him up on it because of their long history as friends. Shortly after Con got pissed off at ASICs being announced (since they obsolete the GPUs he had only ever worked with), he threw a fit on the forums making accusations that vendors didn't provide him devices (despite his never having been involved with this up to that point), and stopped accepting even bugfixes to the code he maintained from me, forcing me to effectively fork the rest of the codebase as well just to have the bugs fixed.

BFGMiner continues to advance in both core functionality and FPGA (and soon ASIC) support, as should be obvious by now.

Edit: Forgot to mention, nelisky contributed and maintained the Ztex driver from March until May.

Edit: I should perhaps also mention, there have been at least a couple of significant reorganizations delayed due to the cgminer team's aversion to collaboration and cooperation, but BFGMiner will be getting the result of this work very soon, maybe even before ASICs. It's a shame it took this long, though; Con is a great programmer, I don't know why he can't just work as a team.

Edit: Observe for yourselves, the authors of the code in question the moment before Kano forked it (in cgminer's own repository): BitForce and Icarus

Just add a StratumAddresses to the config.
