I have a quick question about POS and YAC. Recently I think I've held my coins long enough to the point where I should be getting some POS from them, but I've noticed something happening that I don't quite understand. My wallet will make a transaction to a blank address for 0.00 YAC, and move a certain number of YAC to the "Stake" field in the client (right now I'm showing 2520.86 YAC) as "Stake" in the client. A few days ago the same thing happened but it showed 5000 some coins as Stake. After 512 confirmations the Stake balance moved back to my normal balance but I don't see any confirmation anywhere of any coins being minted through POS.

I saw a screenshot the other day of the PPCoin client and it showed in their transaction history the various amounts they minted through staking and I didn't see any of these empty 0.00 YAC blank address transactions like I am getting with YAC. What's up with that?

Once they mature (520 blocks) you can see the YAC received looking at "Show transaction details". Before that it shows 0.0 YAC.

Before maturation, you could substract the Staked amount to the "Net amount" shown in "Show transaction details".

Or you can check the transaction ID on yacexplorer.tk and see the POS Generation value.

Ah, okay. I see now. Thanks!

What is this Proof of Stake... and how is it different from other coins (or is it)?

In a few words - proof of stake increases your balance roughly by 1% yearly if you do not spend your coins.
Can anybody say if there are any chances to see current stakes in daemon?
Since I run my yacoind for a long time, have not spent any coins for last 35-36 days but


does not show anything new and balance remains the same

Whoa, I had no idea about that. I was under the impression when people talked about Proof of Stake they just meant like... proof that the coin works, lol.

Does this mean that we want the coins in our wallet? I have a lot of them on a pool still that I haven't withdrawn yet.

somehow yes. I doubt exchange will add proof of stake to your balance  ;D but this was made not for investment but for chain security

lol, anything helps though! Thanks for the heads-up. I just put in my withdrawal request, :).

In case anyone is wondering, this is what it looks like in the transaction details:

From looking at the source, I think it's 5%/yr with YACoin:

Wait a second though... with what the image shows (the one explaining PoS)... this is only given if *you* generate a block? So mining in a pool means no PoS since the pool would be the one that gets it?

It means the POS block that you generate. If your coins are sitting on a pool you will not get the POS because they will be in the pool's wallet and therefore the pool will get the POS coins if they sit there long enough to generate them. You have to keep them in your local wallet for long enough to begin generating POS blocks to get the rewards.

It's generated independently from Proof of Work mining. You just need to have your wallet up and unlocked for stake mining.

See https://bitcointalk.org/index.php?topic=187714 for more info.

EDIT: And to amytheplanarshift's point, the coins need to be in your wallet, and not moving around for at least 30 days to begin generating stake.

okay, so when your coins go to "stake" to be held for 520 confirmations - do you see it in "listtransactions" output??

Which is weird, because when PPcoin first came out, I bought 2000 coins, and then had 2 PoS blocks with a value of ~900 coins each, then i had a balance of 3800 coins. That didn't seem like 1 percent to me.

This is interesting... are these (PPC's) the same steps we take for YAC as well, or is it different?

My bad. As rbdrbd noticed - it's clearly 5%/year. not as Novacoin 1-100%/yr nor PPcoin

YAC gets it's POS implementation from Novacoin, which got it from PPCoin, so yes, those steps should work with YAC (I got my wallet working that way too).

I got my first 1.7% annual stake block generated somewhere around day 35-40. The PoS generation should become easier and bigger until 90 days when you start losing interest. There's still some luck involved or I'd get 5%/12 every month.

Mmmm, it says to add a bat file where the ppcoind is (or in this case yacoind) but that's not in my QT folder (nor in the zip where YAC is located). Is there something special we have to do here?

yacoin-qt can stake just as well as yacoind. The process is completely automatic.

Ahhh, got ya. Thanks, :). So keeping the client open as much as possible is needed... but the only PC I have running 24/7 is my mining one, and based on what I read elsewhere that wouldn't be a good match since staking needs CPU power?

PoS aims to be as power efficient as possible. It is mining, yes, but it's using FAR LESS cycles than regular mining. Basically, you won't even notice it.

Usually less than 5% CPU from what I have seen.

For stake generation, any flags in the client which need to be set (on windows)?

Based on a bit more reading, it appears you just run the wellet itself and leave it up. Doesn't appear that there's any way to know if you're doing stake mining or anything though...
