[ANN][GRA] Graincoin - New PoW/PoS coin | Fast, secure | Version 1.5 Released!

[mkimid]

I edited the message. please re-read

Thank you for the answers, I am concerning about two issues actually,

First, PoW diff is adjusting while mining PoS blocks,
        From the source codes which has been posted before,
        It can not be happen,
        Maybe the code has been updated, so, I do not have a major issues here
        Because of it is same as before,

Second, Diff looping,
        When small number of PoS blocks between PoW (0 ~ 5.....), Diff is increasing fast,
        and, it is going to 3~5.xxx
        after mining huge PoS blocks such 10, 20,.... some time, more than 40.....
        it is come back to 1~2.xxx
        Actually, it is the old problem, not a new issues,

my guess,

       when mining small number of PoS, it is not have time to adjust Diff to matched on 30 seconds,
       so, it has relatively lower Diff and block time.
       unfotunately, when calcuate Diff of PoW, this block time has applied to changed PoW,
       so, Diff of PoW is keep increasing

       if Diff of PoW is going up to some limit or Unluck situation,
       there are many of PoS is generating again, PoS can have enough time to adjust its Diff to match on the block time.
       when PoW has found, PoS has stabled, and PoW will have good time gap because of the effect from PoS has minimized,
       so, Diff of PoW is returning to the normal level,

       This situation is repeating again and again,


History
    
      Diff looping issues are started long time ago,

      When PoS has disabled, this problem is not happen, becasue of there is no PoS to affect on PoW block time (Diff calcualtion)

      At begining after resolved PoS issues (QT 1.3), this problem, because of there are large number of PoS has generated, and
      It help to stabilize the PoW also,

      Recently, within some time zone, there is not many coin has been mined, and so, lower number of PoS will be generated,
      and, this problem problem is happen again

      When generate large number of PoS is generating, this problem is gone,

      IF QT 1.4 has activated ? chance of PoS will be redueced from 12X to 3X,
      it menas 4X more chance to make this problem,
      I worry about that,


My personal opinion about this issues,

     Whatever blocktime is, Diff of PoW should be stable ~
     and, PoS should be stable also,

     Actually, this kind of issues are happen in PoW/PoS coins (and PoW also, if adjust diff each block)
     (1) in PoW, they are failed to estimated/calcuate Diff for next block (mostly, missing or weak interpolation)
     (2) in PoW/PoS, they are in the recursive calculation

     Whiling writing (22:09), the diff has increased to 9 ~
     5, 6, 6, 7, 7, 9, 9, n, n .....
     (while start PoS, Diff has increaed so much)
     (actually, it is why I have asked the reason why adjust Diff of PoW when PoS has started)

     (if much more miners are mining, and PoS timing is good distributed, this problem will be gone)
     (but, it become a big barrier to growing)

Just found my first PoS-Block 

Congratulations.

First, the sources on github are current. Next, the support from the people to the coin is not big enough yet to make these parameters as stable as Novacoin has, for example. Yes, it might be the diff will not stabilize more or less in the near future. We need to spread the word, push the businesses to accept grain, etc. All of us. And I see that the community does this, so I have a faith that the grain succeeds eventually.

Edited: the support means both PoW ad PoS hashing power

Thank you for your answer,

The good thing is the price of this coin is going up,
and, it will makes the new miner considering to join in grain,
and, will become better and better,

Maybe everybody believe it, so, keep mining (include me),

actually, last 4 hours, I didn't got any blocks with 2.2M hashes,
and, it makes me little bit sad ~

It actually tripled its price: yesterday at this time it was 16. Now it is 50.

Thank you for your answer,

The good thing is the price of this coin is going up,
and, it will makes the new miner considering to join in grain,
and, will become better and better,

Maybe everybody believe it, so, keep mining (include me),

actually, last 4 hours, I didn't got any blocks with 2.2M hashes,
and, it makes me little bit sad ~

As PoW blocks are the main source for coins, hopefully with 3X kicks in the mining (especially the diff) will be much better.

Hi,

We have created a new Grain pool @ gra.cryptochomper.com for anyone who would like to sign up and start chomping....



We are planning to introduce other pools later on so any feedback welcome.

CryptoChomper

Great pool, switched all my miners over.

[kovand11]

I hope, it gets a bit cheaper. I want to buy more.

[infofront]

It seems that even with the increase in price, it's unprofitable to mine.

It is a nice pool... but why you change the link (I fixed it in this quote)? Be careful guys, look at the link before you click on it.

based on current hashrate, GRA price would have to be 0.00000452 to be a top 5 coin.

Hugely undervalued right now. I might have to pull funds from other coins to buy more GRA.

I would say it is profitable to mine grains now than litecoin:

(0.029×50÷3998)÷(2000÷2) = 0.000000363

The 2000 coins a block is an average including bonus blocks (counted through some week period of the chain)

Absolutely, right,

Just simply, I have got 23 blocks for last 24 hours,
But, I am not lucky, because of I just got one 8x block only. ^^

Anyway, 47657 coins are mined, and I have received  115000 coins (thank you so much)


The value of mined coin with 2.2MH/S

        47,657 * 0.00000046 = 0.0219BTC or 0.73LTC
        115,000 * 0.00000046 =  0.0529BTC or 1.76LTC

* I have posted the history of my mined result everyday

        The expected mining with 2.2MH/s : 0.5534LTC (at 3998 diff)

Clearly, even I just consider the number of block which as mined,
much better than LTC mining,
and, Grain coin give to us 5000 free coins, it is an extra breathing,
but, it will be finished soon..  

Anyway, I have to start mining again

(actually, I have mined NEC for 4 hours, to track their block behavior ^^;
it is one difficult to track because of there is no explorer -..-
This coin give me a motivation to learn more and more, )
