Topic: [ANN][GRA] Graincoin - New PoW/PoS coin | Fast, secure | Version 1.5 Released! - page 102. (Read 177070 times)

more fud, the thread you listed is from the original giveaway, no one has posted in 8 days in that thread, the message reflects the attack/fork.

the coin is not PoS only, no more fud plz.

Considering the circumstances, I have every right to raise alarm bells.

And now that I've seen this ..  https://bitcointalk.org/index.php?topic=361887


Please explain how a PoS only coin is good for the community.

Was there anyone else involved with GRA's code ?

i hope its not gonna be anytime  soon cuz it  will not get dumped like other alts

How long will it take before this currency potentially shows at some crypto exchange?

Going to friends place to join the New Years party.

May this (GRA) be the success story of the new year 2014!

And happy New Year to everyone on the grain train!
Love you all!  

Hi, Bosian

How are you ?
I have capature a screen to explain what is happening now.

1. I am living in NJ, USA : EST TIME ZONE
    so, Please, just compare the minutes and seconds only (not hours)

2. in BFGMiner Screen
    The network speed is going up, and hit Diff 4
    and, keep couple of hours,
    and than, it is going down to Diff 1
    and, this process is keep doing again
    This kind of pattern is happen always, my means, each block will have the difference Diff,
    and, It affect on reject (?, maybe, I am not sure, just guess)
    and, it affect on stale (my means, the keep chaing of time... anyway, sorry for too stupid idea)

3. The networkhashs from Grain-QT 1.2 (actually, 1.1 also same)
    at block #60327,
    at block #60328,
    The hash rate has been decreased dramatically, and Diff also have been changed.
    Technically, something wrong
    it is hard to believe the actual network speed is changed like this

4. Check the time between Grain-QT 1.2 and Minder
    * I have used 1s scan time, and 1s logging time for miner
    * I have put, getminerinfo every 10 seconds, to find the changing point
    -> Actually, Miner Detect the change of diffculty much earler than QT
    -> The changing point from 4 to 1
         (in Miner)  xx:08:08
         (in QT)      xx:08:53
    -> I have thought, need one more block to update the current hashrate in QT, yes, it is right,
         but, sometime, it is happen over couple of blocks (After couple of new block detected on network message)
      
Anyway, I am not sure, what is the problem,
maybe, It is just my computer problem,
or maybe, it is just my network problem,
But, only happen in GrainCoin
I have tried to with QT1.1/1.2, Actually, when blockchain explorer has recovered, I have tracked block chains,
and, I found it is matched

and, I feel, there are too many PoS blocks via PoW
(the diff on screen and actual diff is too much difference and growing more and more)
I know it is a technical choice, but,
it makes less attactive for this coin for mining.
In fact, it is why there is not many miners interest on mining PoW/PoS type even it is much more advanced but too early to accepted in this area
(just my person opinion)




p/s : sorry for bothering you again, I like graincoin too much ~ that is why I have too many stupid question, please forgive me.

There is no any offer to sell GRA. 
Let's start.
WTS 500000 GRA, PM offers

^ this, and if still problem, search this thread for "addnode" and try repairwallet command in console.

Remove everything from your User\Appdata\Roaming\Grain folder except wallet.dat and grain.conf if you have a conf file there. Then start 1.2 and it should start working. Make sure you make a copy of wallet.dat so you wont lose it incase something goes wrong.

One of the nicer looking logos.

hi all,

i hope someone wants to help me.
i would like to get mining grain again but my wallet cant sync. i have enough connections and the green bar in the bottom shows up with approx. 16000 blocks to go. but it stays at that number and when i start up later i have more blocks to go.
i do not know this problem from any other wallet.

i run the old version of the wallet, the new one says ''unable to load block.dat'' or something like that.

so maybee i need the new wallet? but do not know how to get it working,
or is there something else i could be doing wrong?



thanks for the help.

Looks like a nice active community here. Maybe Ill give some grain a shot.

this what I been saying!! diff going super high!!

I think that the thing counting time since last block is having a max value or size of PoS blocks it can ignore. ie

after x PoS blocks in a row it starts believing they are PoW

or perhaps it is confused when there are PoS and PoW in the same blocks.?

either there is a variable somewhere which is entered wrong or there is an overflow error occurring during PoS generation.

it may be that certain PoS blocks are not being read as valid data and are being treated as PoW by default,

ie code says "check for PoS or PoW" returns "hmm this doesn't look like PoS, must be a PoW block"

The diff seems behave strangely for a few blocks (pretty high), then return to normal. Now the diff seems right. I don't know why it jumped so high at one point. Will keep watching it.

Seriously,
i have got the similar thought before,
If make averaging some days, it should be saturated on the target block time.
But, it is keep shaking periodically with high amplitude,
Anyway, it will disturbing the miner and efficiency,

Thank you for your answers
And sorry for so much bothering ~
