Generating Bitcoins with your video card (OpenCL/CUDA)

Or everyone could do the obvious thing and donate to me to open source it.  Why do you find my work so worthwhile to crack, yet you won't help the community by donating to open source it?  You do realize that you can crack it all you want, but without the source code you'll get stuck with an outdated client very fast.  I'm on the verge of releasing an OpenCL enabled build as well.  Do you really want to be the person who changed my mind about releasing it and providing enhancements to the CUDA version?  I'm sure the community will let you know how they feel about this.

Yes, the community prefers to work with people that have the open source mindset unless there's no expertise in it, or the closed source is amazingly better that all others. But hey, that's just me

Your code may be great, and your heart in the right place when you say "convince me to open source", but the paragraph you just wrote spells out "either you pay me or I'm not releasing the hostages". The pun regarding ransomware is well intended, but in a satirical and well intentioned manner! I told you, I understand perfectly what you are trying to achieve, we are all going for the same thing. It's the route you chose that I'm not comfortable with.

If I will get enough bitcoins, I will fix SendMoney() so users can safe send bitcoins.
But also I will give all donated to me bitcoins if you will agree to open source code.

I am very interested in opensource OpenCL version. I hope you will release it soon.

I won't deal with those who openly attack my work and provide cracks.  Remove your link and promise not to do it again and we'll talk.

Your build is under free MIT license, so I did not do anything wrong/illegal.
I need some time to think about your proposal. I will lose influence on you.

I suggest you reread this portion of the readme.txt:

Code:

This is a Windows 32 bit CUDA enabled build of the bitcoin client, based on SVN
revision 153.  By using this release, you agree to send the author,
1HZNsUqQxKVLmfPfCAzLwrnVDzx8CxwxnM, 5 bitcoins every time you generate a block
while using the CUDA bitcoin miner.  This payment will be automatically sent
when a block is generated.  If you do not agree to this, you must not run the
client or attempt to modify it in any way to circumvent this.

[LZ]

Okay. If I "agree to this" so I have the right to "attempt to modify". Good luck, puddinpop!

[puddinpop]

Okey. If I "agree to this" so I have the right to "attempt to modify". Good luck, puddinpop!

You missed the point that my modifications are not MIT licensed, so you do not have the right to distribute any derivative work.

[LZ]

[Immanuel]

Haha, he should fix that.

[puddinpop]

No matter how hard you try, it doesn't change the fact that my modifications are not MIT licensed, nor do you have the right to alter and redistribute them.

[LZ]

We do not live in parallel universes, do we? But now I am not sure.

His geographic location only has a bearing on his rights under the license, not the license itself.  One license doesn't magically become a different license based on where you are, unless he really is in that parallel universe.

Are we really discussing intelectual property licenses now? I mean, really???

There's this friend of mine, who I greatly admire, that says that "the world is not made of laws, but of people". When we need to hide behind license agreements and we didn't even leave the neighborhood, something is really rotten. While I must say that puddinpop has a point, he can actually licence sw based on MIT core in whatever or whichever way he feels good about, I just think that making a point of it goes to show a bit about his education towards open source and its beliefs.

So, in my mind, we get a 10000 BC bounty for him, he makes us a pretty opencl version and then states he found a way to increase hashing, 10 fold... but now he wants 10 fold the bounty! I'm off this thread now, I hear my conscience calling me.

If there would be a 10000 BTC bounty I would open source it right now.  You understand I spent a considerable amount of time and effort creating this and want a return on my investment.  People cracking it and nit picking about perceived license issues when it is clearly not open source just makes me not want to bother with releasing anything.  Why should I bother if people don't respect it?  Anyway, like I said I'd release all the source given a large bounty, and If I discover some magic way to increase the hashing rate in the future (not likely) I would not want any more.

necessary to achieve the ability to interact independently created computer programs with other programs
and can not be used to develop a computer program, a type essentially comparable to the decompiled

Lzsaver, you are violating puddinpop's copyright at least when you distribute the modified binary. I suggest that you (or a moderator) remove the link to the cracked binary.

Edit: Just to be clear, I don't think anyone should use a closed source Bitcoin client and I would really like GPU generation to be open source. So I will put my money where my mouth is, I will donate 1,000 BTC to whoever releases the source for a GPU (CUDA or OpenCL) client that is cross-platform once the code has been vetted by people smarter then me.

[LZ]

I am not violating puddinpop's copyright because his build is licensed under the MIT.

woot, finally someone steps up! I wish I had the time, as it's a ton of fun to optimize code like this. But to be taken seriously you'll need a trusted wallet keeper to collect all donations, serving as escrow. I could make mine (assuming a CUDA only solution) work for linux and mac in a couple of days, but my employers wouldn't be too happy about it!

Windows? I have no idea, would need to set up a build machine and that I'm not looking forward to :p

But anyone wants to pick up where I left?

[Anonymous]

I can provide a neutral escrow service for you as I dont generate coins so I dont have a dog in this fight, except the need to ensure the network is stable and secure.

I believe developers should be rewarded for their work. What is the target we are shooting for here?

If people agree I will setup a mybitcoin account and post the address.
