Groko's been doing some work on the POS miner through the YACoin client. Looks like he found a world around to some of the long-term concerns. I thought I would share the link here to increase awareness. I believe he recently made a pull request to have this items added to the sourcecode.

More excellent additions by Groko! Well need some community consensus on this, so everyone that can, please provide your opinion.

I certainly prefer seeing coins combined than split. Since it doesn't fork the blockchain, if some unforeseen problems arise, it should be relatively easy to go back.

Hmmm, see, everyone has their own opinion on what to call it. I refer to Windmaster's post on the matter as my argument for name

https://bitcointalksearch.org/topic/m.2332885

regarding the N-Factor schedule - it's in use by no less than a dozen coins..

P.S. Sairon - any word on when the wiki will be back?

YACoin is on the list, but I need info.

What is the total supply? That is blank in first post.

What exactly is the PoW algo? One part says Scrypt-N SHA-3, another says just Scrypt-N and in the next sentence talks about SHA-3 Keccak. Finally the miner uses Scrypt-chacha. I know the SHA-3 winner is Keccak but how does it fit into YACoin?

See this for PoW algorithm:
http://forum.yacoin.org/index.php?topic=322.msg1495#msg1495

...

According to above post post, the library is Scrypt Jane and Scrypt Chacha is one of the mix functions. The hash is Scrypt-Keccak512 with N increasing over time

I will call it whatever you want, but I think Scrypt Jane or ChaCha are incorrect.

call it scrypt-yac, it's got its own Nfactor schedule anyway

Done.

If someone would write up a quick description, I will make a new page for Scrypt-YAC and make an entry here: http://cpucoinlist.com/cryptocurrency-algorithms/

Regarding the total supply - this is from sairon :

Quote from: sairon link=http://forum.yacoin.org/index.php?topic=514.msg2282#msg2282

That's ~~theoretically unlimited~~ capped at 2,000,000,000 coins. However, transaction fees are destroyed instead of distributed to miners and proof-of-work block reward decreases with increasing difficulty. So IMHO it will find its equilibrium somewhere lower.

not true, there's no coin supply limit. the 2 bil limitation applies only to a single input.
that said, the equilibrium part still holds. it all depends on how the tx volume, pow supply and pos supply balance out.

I am going to use one word to describe coin supply. Would you like infinite or unlimited?

unlimited describes it much better than infinite

Thank you very much btc-mike. Is "no set limit" acceptable? Like with PPC, YACoin supply could eventually decrease due to transaction fees being destroyed.

I would have to go look at some other posts on the total supply question.

YACoin uses Scrypt-Chacha (aka scrypt-jane) with increasing NFactor as the mixing algorithm and SHA-3 (Keccak 512) as the hashing algorithm.

to contrast with Litecoin, Litecoin uses Scrypt (salsa 20/8) as the mixing algorithm and SHA-2 (SHA256) as the hashing algorithm.

edit: duh, mix, hash backwards...

This is current data:

yacoind getinfo { ... "moneysupply" : 24557303.97361400, ... }

With current difficulty some 80K new coins get generated every day:

yacoind getmininginfo { "blocks" : 606896, ... "difficulty" : 0.00710212, ... "Nfactor" : 15, "N" : 65536, "powreward" : 57.02000000 }

The GPU Advantage scores are based on R9 280x and an AMD FX-8320. I chose these two because the R9 280X is fairly common and has been easy to find published numbers. CPU hash-rate numbers are more elusive so I test on my desktop.

Of course, there are a few problems with this approach. Some coins have faster ATI GPU hash rates. The FX-8320 is slower than the new Haswell chips. Some CPU mining apps take advantage of the Haswell's AVX3 instruction set.

I can test the CPU and get a number, but I still need published GPU numbers.

That's going to put YACoin on the CPU friendly coin list for certain

Please make sure you use the CPU miner optimized for YACoin. I've got published source and binaries on github at http://github.com/Thirtybird/CPUMiner

I don't recall seeing anyone publish 280x numbers, but as a 3GB card I would guess it's going to be in the neighborhood of 1.5 KH/sec. If anyone has one and is willing, I'll work with them on settings and we'll see what it can do.

I was thinking about this more, I will put YACoin back on with the GPU Advantage shown as "researching". I do that with most coins when they get a new GPU miner.

I can do the CPU testing tomorrow.

A few people told me to check YACoin again to add to CPU Coin List since the difficulty made GPU mining much harder. Is that true?

I tried to check the HW stats on wiki but wiki is dead.

Is there an up-to-date list of GPU has rates?

I've got some insight for you:

Radeon R7 240 4GB - 1.1 KH/sec
Radeon R7 250 2GB - 0.8 KH/sec

Core i7 3610 laptop - 0.31 KH/sec

No GPU with 2GB of memory or less has shown to hit over ~1.2 KH/sec (750Ti). I don't have solid numbers on the higher end AMD cards with 4GB, but none of them can utilize all of the available shaders without lookup-gap going to the moon which really kills performance. If they hit much higher than 2.5 KH/sec I would be surprised.

so, the GPU advantage is likely less than 10x depending on what hardware you choose for GPU and CPU.

And I'm getting 410 hash/s on an I7-3770S which equates to 22 cents per day before electrical costs --> www.whattomine.com

I'm wondering how that matches up with other CPU coins on the list regardless of the 'GPU advantage'...

It can net 270h/s mining monero, so: http://www.whatmine.com/

While I have been further researching possibilities of improvement I have come up to rather lengthy discussion, after which a proposal has been put just a few days ago:

http://eprint.iacr.org/2014/452.pdf

Could yacoin be upgraded with this in order to help solve checkpointing problem (perhaps even chaintrust?).

It's a lot of material, if you are curious just check "3 Protocol" section in the document and first post of originating thread:
