people don't mine it so much in part cause of the high n factor (I mean, look at UTC's thread to find prime examples of this...people whining, "why don't you just stay at nf 11 or back or whatever").

with the right promotion the YAC multipool would be a great leap forward! Even people with sha256 or scrypt asics could "mine" YAC and keep PoS minting it. Perception is key here, and even though mining and exchanging yourself might even bring better results at times (or not, depends) people will prefer the easier to setup and operate option.

I posted this in forum.yacoin.org , but I think it is worth sharing here...

30,000 YAC Bounty - YAC Multipool

First, 30,000 is really a low value for this bounty. I hope other large stakeholders pitch in as the investment would be beyond worth it.
Coins won't be touched until bounty is fulfilled per usual: YLNhNhRVspJMZLBN4PcSjkLsVTd3TMaq7R

The multipool must meet a couple important requirements:

-Payout in YACoin ONLY
-Be able to mine top scrypt-N and scrypt-chacha coins on different NFactors

Please bare with me and hear me out...

Some people may view a YAC multipool as just trying to steal from an idea created by BlackCoin, and since BlackCoin is the first to implement the idea, YAC won't garner the same results. The idea of a multipool is obviously not a new one, but using a multipool to pay out in an altcoin is quite a leap. One may think, as I did, there would be a huge incentive for the multipool operator to simply payout in the dominant bitcoin since much more people have already bought into bitcoin--more users, more profits for the multipool operator. But BlackCoin has proven that the huge increase in price, marketcap for such a coin with a good multipool makes it a very promising endeavor. Along that point, BlackCoin makes a lot of sense for a multipool as it became pure POS from POS/POW hybrid. Economically earning interest has a lot of meaning. The perception that one's money is earning money is a big deal, and some form of inflation is important for price stability long term.

So why would a multipool make sense for YAC? I will use a personal anecdote. I have mining rigs with the following cards:  R7 240 2GB, R7 240 4GB, R7 250 2GB, R7 250 4GB, 5770. At one point, YAC was the most profitable coin to mine for every one of these cards. Now, the 4GB cards are the only ones where YAC is the most profitable. Even though I would still make a profit mining YAC directly with the other cards, it would be more cost effective for me to mine other coins, trade for bitcoin, and then buy YAC--which is exactly what I'm doing now. However, this technique is rather tedious and time-consuming. It would be much easier to have a multipool to make this process easy and seamless for me.

What has happened with YACoin and other scrypt-jane coins, and continues to happen (just go to the ultracoin thread), is that the NFactor increases leave miners disenchanted as their cards no longer achieve the same performance. Even though some of this problem is purely perception based (30 khash/s to 12 khash/s after an NFactor change doesn't mean your earning less than half as many coins), a lot of it has to do with, for example, a 5770 performing well at NFactor 12 but poorly at NFactor 14 relative to other cards. One could sell their 5770s and use that money to buy the more optimal cards, or one could use the workaround I do (described above), or one could just sell their stash of coins and move on to a coin that is more suitable for their already setup hardware--which has obviously been the tendency. A multipool would change this reality.

I submit YAC is THE hands-down, absolute best candidate out there for a multipool. Ignore my bias... YAC will be THE first coin to reach NFactor 15 and all subsequent NFactors. YACoin is THE only stake minting coin out there with user-friendly features to include a checkbox to enable stake minting (infinite kudos to Joe_Bauers and Groko). Plus, YAC is reaching a point where proof of stake is accounting for a significant portion of newly created coins. You don't even have to mention YACoin is the first coin ever to incorporate NFactor changes and also has the best community of all crypto.

My apologies for the long dissertation--at least the important part is at the beginning. Please share any thoughts.

YAC is up for votes now on MintPal https://www.mintpal.com/voting

I know this went sooo well with cryptorush... :/

I strongly advise against anyone buying votes. Besides, the idea is that YACoin shouldn't need to buy votes because popular demand should be that high.

haha ok I'll pm you an offer. I was going to ask you about that GPU farm of yours, as I remember seeing some teaser pictures. I can only imagine how impressive it is. Those 1 GB RAM cards may be money for NFactor 13 scrypt-jane coins (just one now... at the moment!). Pump and dump is perfectly ok as long as it's not YAC

Thanks for the recent update to the post. I guess we need clarification on the total supply limit?

Hehe, try me.  

I did get one offer from one of the main YAC community members for a small chunk of what I'm after, but I didn't reply for a few days because he typo'd the asking price and left out a zero.  By the time I inquired whether it was a typo, he already offloaded it.  So, anyone still looking to offload a lot of YAC, I'm still in the market for ~100K YAC or so.

I've left a few blade servers chugging along at idle priority with a copy of the CPU miner for the last 6-7 months or so, to soak up idle CPU time on a portion of my render farm that was going to be left running continuously between render jobs anyway.  Looks like it has accumulated about 17K YAC so far, but I'm looking to hold a larger stake than that.  While I have a massive GPU farm (some time back I posted photos of some of our electrical infrastructure in one of the LTC threads, including our 900kW service entrance and power distribution room, but won't post photos of the GPU farm itself until GPU mining is no longer profitable), almost all of the GPU's have 1GB of RAM so are best left mining LTC.  The farm is large enough it would completely whack YAC difficulty, so I probably wouldn't do that even if the GPU's had more RAM.  I did that to Elacoin a few times for entertainment value though.

I'm glad you put "better" in quotes. R7 240 and R7 250 (2GB and 4GB)--these cards are more accessible as they are cheaper and less percentage of your revenue goes to electricity.

Only 270x 4gb, 2gb is a bit mediocre...750 ti 2gb is amazing :p

Crazy. So 270x and nothing "better". Prolly some 750ti love too.

I get 2.7KH/sec out of a 130 KH/sec scrypt card and 2.9 KH/sec out of a 110 KH/sec scrypt card.  Both rigs together with 8 cards would be 1MH/sec scrypt (maybe), but together get 21KH/sec on YACoin.

Speed is not linear...I get 2.5kh/s out of a 80usd gpu with yac.

I ran some numbers and I just cant see it. Even if you get 6khash from 1000khash scrypt equiv.(what I doubt), you are still going to get 0.003 as opposed to 0.005(VTC).

Am I missing something?

Are you running it under FASTCGI ?

https://github.com/lirazsiri/blockexplorer might be another choice.

Various tweaks merged to the first post.

I dont know squat about python, but isnt there any simple way to memoize?

Edit: Seems fast enough for me Will add YAC later today.

Oh how I hate ubuntu... I guess it broke after I updated some packages. Will fix it in a bit.

As far as making the explorer faster goes, well... It's not an easy task as the Abe block exporer source code is a nightmare performance-wise. There's no proper caching, everything is recalculated from raw data on every single page load. Adding caching proved fairly difficult as the code is just not modular enough, so I kinda gave up.

I'm not sure their exact origin. But I suspect they are mostly related to mining (PoS and/or
PoW) where transactions that were supposed to be deleted due to orphanage were not
deleted. I also suspect I had situations where I had two or more clients with copies of the
same wallet making PoS blocks simultaneously. There was also that period of time when
PoS mined blocks would get automatically orphaned because of the new trust rules automatically
orphaning PoS blocks that follow right after other PoS blocks. Whenever a transaction fails to
get deleted it becomes permanently inserted into the wallets cache of transactions. I discovered
you can erase all cached transactions without loosing the important stuff like the wallet keys and
account names. The block chain is after all the real master record of valid transactions.

Looks great. What "bogus transactions " for example ?

I haven't chimed in for a while. This single thread form of communication is ... so ...
how should I put it ... primitive! Hehe.

I've been busy with an exciting enhancement to the QT client I hope will get good reviews!
It started with a "I wonder if would be possible to...." and then boom. I figured out how
to do it. "It" is a new balance column in the transaction view that actually reports the
correct balance! It's running great now, so people with their own builds and good backup
habits please give it a try and let me know your feedback.
