It was only the wind.
With the help of Wolf` and djm34, some problems with PLUCK have been found that break it's cryptographic security (ie, always including a plain sha256 hash), as well as some non-obvious performance optimizations that are not intended.

So, the hashing algorithm has changed some. I think in it's current state on github it should be good, but I'm still working to verify this.  
where is the new algorithm code?
i'd like to check again.

good work.i think this algorithm have no disadvantage.
this algorithm is preferred for CPU mining.how fast is the GPU miner?

There is none yet.
Are you working on one? / Will you claim the bounty?

It feels like you are following me (or maybe i'm following you) everywhere but I guess we're both going to coins with different algos. Smiley

No.

do you wanna build it?
i checked the code,
there are many Modulo calculations, CPUs have division instruction set,will  get better performance.
and many random access to fragment memory,large L2 or L3 cache and low latency memory will take advantage


Nope. GPUs have native division, too.

You should add a better theme to it. Right now it looks too plain.

P.S. I registered Supcoin! Mwahahaha! (before it went down, obviously)

One of the modules screwed up the forum.  So I have to reload.  I am setting it up on another site.  Should be up again soon.  I will also test a couple of themes.   Grin
Aww what! That's unfair! Someone stole The user Supcoin from me.

Can I please be a mod btw?

I noticed the title still has "logo contest" in it.

I thought that ended. It did, right?

I liked your last release, this one should be fun too -- but I need a node to connect to first, the only seed seems to be down!

I am totally watching this, although I am disappointed that the dev wants a GPU miner out asap. I would've liked it to be cpu only. Oh well...

But I am still watching. Smiley

People will make GPU miners whether I give out rewards or not Wink

Anyway, the algorithm is finally I think complete with all bug fixes. The github code has changed (the Windows build published earlier is now invalid) to reflect this and the test network was restarted.

Various properties fixed included:

1. Final sha256 collapsing loop had an off-by-one error that caused it to actually do nothing
2. Mixing is now done using 32 bit instead of 8 bit. This should allow for better mixing and with less shortcuts being possible
3. Because the final collapsing loop didn't actually do anything, it didn't carry over the unmodified sha256 hash from the very end of the hash, meaning PLUCK wasn't carrying over sha256's cryptographic properties theoretically (this also could allow for a number of other theoretical attacks)

Because of these problems, there's of course been some delays. I need to port the CPU miner forward now, and then actually start on all the other stuff. When I get these two things done and confirm testing is good, I'll put out a release date

In order to raise tangible funds to motivate GPU miner devs, I am now hosting a donation address for Bitcoin.

1K6cUbtsn5xinD8XfjnTn7UnsMriLhZaGD

The first GPU miner to be created (AMD or Nvidia) and published under an open source license will receive all the money from this fund.

I'm putting in 0.25 BTC of my own money. I encourage everyone to donate what you can to help make this a lucrative bounty.


cmon guys, we need more donation to help earlz get this GPU miner  Cheesy

Added 0.1 Wink

The logo winner is logocreator! This logo wins!



After launch, I'll PM you for an address and will send you the reward

you have already decided on the start-up time? I would like to be with this coin, I hope the announcement of the launch will be 1-2 days before X

I was waiting on a number of things to get completed before I committed to anything. All the major things are now completed and/or working. This includes:

1. Gitian, for building binary Mac, Linux, and Windows wallets at launch
2. minerd, a CPU miner for pool mining (also is faster than in-wallet mining for solo mining as well)
3. Some testing and difficulty adjustment testing.

The coin itself is looking good and the only thing I really want now is a Windows compile of the CPU miner and a NOMP module for pools. I'm going to look into these two and then will probably set a time and day for launch. Hopefully in a 3-4 days

0.9.3 versions solomines and connects just fine with any miner.
but what has changed with 10.++ versions, those wont get miners connected anymore??

They removed the "getwork" RPC call, in favor of getblocktemplate. This means you must pass into your miner an address as well for solo-mining (if not mining in the wallet itself)

In other news, I just now completed a very raw and barely tested minerd (CPU miner). https://github.com/Earlz/pluckcpuminer (it's 3:30am, I mined 2 testnet blocks with it and called it good lol)
This will be used for CPU mining against a pool.
