They want to avoid algebraic attacks

And addition is very cheap way to get high multiplicative complexity on commodity hardware.

Don't they have rotates for that?

Cheap in software, free in hardware.

And this is a question from someone with bitslicing experience? Wink

Smolen... that's called lazyness Cheesy

reorder was making a joke about some hashes using addition without really caring about the additional properties of addition comparing it to XORs because a hardware adder is just an XNOR with some ORs looky here http://en.wikipedia.org/wiki/Adder_(electronics)

Oh, damn, those "additional properties" almost drove me mad

Could easily help with some ranting about how academia hash designers choose addition over xor for no reason, making life harder for hardware implementors.

Dat carry you have to carry around.. By the way Gielbier is missing you on the IRC.

...

I'm offering a 10k skc bounty on an opensource FPGA implementation of the skein algo.

I am an FPGA dude and stumbled upon SkeinCoin. I just happen to have working Verilog code for Skein512 and SHA256D from other projects. It seems like I could put together an FPGA miner in short order if I was inclined to do so. Should I consider mining SkeinCoins? I can't tell if folks here would like this or not. It may swamp the network hashrate and frustrate CPU/GPU miners. However, if I make it open source and it becomes widely adopted it will likely drive the price up so anyone who's been mining for a while will see their previously mined coins run up in value. It could breath new life into SkeinCoin which may be welcome with it's latest woes.

So, SkeinCoin FPGA solution ... Good thing ... bad thing?

To quote a large sportsbrand:
Just Do it.

Skein FPGA solution, is progress. I would appreciate it as it would strengthen the network. Now most ppl are just bulk selling their GPU's and buy Gridseeds, which took at hit at the network hashrate for Skeinbased Coins.

(ps: Reorder the CGminer/POCLBM dev from SKC, is most of the time in #skeincoin on freenode. If someone could help you, it would be him)

Hey, I am subscribed to this thread too

But but... hardware adders are there for a reason... i dunno... y.. u... no...

Yeah, and take more transistors, power and latency than XORs, let alone XNORs. Not reusable for reverse operation too.
