Specifications
No premine
Proof of Work: Scrypt-N SHA-3
Proof of Stake: 0.05 YAC rewarded per coin*year after 30 days
Stake mining: 30 day wait, enabled with checkbox from wallet
Block time: 60 seconds
Block reward: MIN(100, diff ^ 1/6) or variable 0 to 100 based on difficulty
Total coin supply:
Difficulty adjusts every block
Configuration file: yacoin.conf

How it works
YACoin is the original creator of Scrypt-N Proof of Work. YACoin chose a PoW algoritm SHA-3 KECCAK to further distance itself from other coin creation schemes. YACoin uses Proof of Stake to secure itself from pure PoW attacks.

Proof of Stake is an improved version from Peercoin's implementation. YACoin counts PoS blocks with equal weight as PoW blocks.

[zhaojundong]

thx
i am glad to see it

[forsetifox]

Thanks for doing this Wind. This is the only other than BTC/ LTC that I find interesting.

[aikklond]

so do we update or not?

[larkstongues]

Fantastic! I'm willing to contribute. However I must go to sleep now

[WindMaster]

so do we update or not?

You can if you wish.  There are no functional changes implemented yet, I've just forked the repository a bit ago and started cleaning up the errant NovaCoin / NVC references.  Particularly on Windows, the UPnP and mining performance issues remain at this point, but those are high-priority targets to fix soon.  If you just want your client to say YAC instead of NVC for now, you can update if you wish.  Otherwise if you're running fine on the official YACoin client, wait for now.

[bitdwarf]

Will watch it too. I wish I could contribute actual code. I can get some translations done tho.

[mtrlt]

I'd like to help develop Yacoin further. I have C++ experience from 2005, I've made some GPU miners (notably the first open source LTC GPU miner), but not much anything specifically coin-development-related. Do you use IRC?

[anonynonanony]

glad to see you step it up.

[ny2cafuse]

Good to hear, Wind.  You seem like a sharp guy, so I'm looking forward to the development.  Thanks, mate.

[R_Lem]

I don't have any programming skills but I'd definitely contribute to any bounties collected for whatever might be needed. I'm not rich by any means but I'd contribute. I'll post it over in the bounty thread.

edit: thanks WindMaster.

[seleme]

Good job mate, at some time I've found it strange that you were posting some things considering that you hold lot of coins but I'm glad you stepped up and decided to do stuff to protect your investment (mine too, haha) and you obviously know your stuff.

YAC is definitely most interesting coin from all recently made and as much as original creator disappeared he at least had put some work in it and added some innovation.

I'm shit and complete noob in anything tech related but if you need some hard labour help, just shoot me pm.

Cheers

N is calculated from Nfactor as follows:
N = 1 << ( Nfactor + 1 )

Note on hashrate benchmarks above - Hardware used was an IBM HS21 blade server containing two Xeon E5450 CPU's and 8GB of PC2-5300F RAM (667MHz DDR2), running Debian Linux 6.0, using cpuminer.  4 cores per CPU, so 8 cores total, test run with 8 threads, SSE enabled (AVX not supported on this CPU).  Combined performance of these two Xeon CPU's is in the same ballpark as a typical i7-2600k desktop PC.

really awesome to see someone step up on this!  Really also hoping some of the current YAC pool operators may be willing to share the modifications they made to get YAC working with the standard tools (or perhaps I missed it).  Pools are critical for more widespread adoption, and right now the choices seem somewhat slim.

[Hydroponica]

Hmmmmm, may be hope for this yet...Good thing I bought a shit ton of them, @.0003

Unfortunately for you, you were not that smart (though obviously dying to leave that impression) and spent most of the time being your usual self (prick) on YAC threads.

This one is from few hours ago and it's academic line among all crap you posted :

Why would I waste money on a coin I don't believe in?

But you still have a chance to buy few thousands up to .0005

Nice quote, but that was from a few days ago, actually...And I already bought them, earlier today, at .0003.

No, you haven't as it never went below .00035 and guess who bought it there   (though all sold at that price was not close to shitload)

But again, it's still cheap, sell your dolls and buy few  

PS. sorry windmaster, I know it's not a place for this and I'll stop right now but this one was particularly cuntish these days, was a pleasure to put him on his place.

Thank you for doing this
