Please don't forget to update your wallets to version 1.4. Should you have problems starting it then try the option '-salvagewallet'
Happy mining!

It is a good evidence about PoW/PoS is working well,

245 blocks + 12 x 245 = 3185,   24*3600/3185 = 27.18sec


Possibly, the practical average PoS now 11x : 29.4sec

1.4M, 16 hours solo, 4 blocks, is that normal?

[bee7]

1.4M, 16 hours solo, 4 blocks, is that normal?

5.6M 24h solo 14 blocks. is that different?

Thanks.
Not just GRA, I found that solo mining get less blocks than I found in pool, that's strange.

It really depends on luck. It is possible to find a block with usb stick block erupter (or any small funny device) on bitcoin network in 5 seconds after it is first switched on. But the probability of this event is very low.

Edit: It should be more blocks a day after we reach block #130000

I posted here for discuss how to set the solo parameter, just like I posted ago(in page 107), did I miss any parameter? Thanks.

1.4M, 16 hours solo, 4 blocks, is that normal?

Total number of blocks are 245 last 24hours

And I am pretty sure, the network hash rate is  40~60M only,,

If you have 1.4M, you should have around 3% of chance to find a block,


245 * 3% * 16 / 24 = 4.9 blocks

So, your number of blocks are normal,
But, surely, the number of blocks which can be found is much lower than you expected,

Because of it is PoS/PoW, 12X, practical block time is 360sec not 30sec

If is is just PoW coin, you can expected as 44~60 blocks,

Anyway, This coin developer will adjust the ratio of PoS as 3X,
And, the expected block time will be around 90~120sec,

You can find  12~16 blocks with your hash rate if the network hash is not changed dramatically,

Anyway, i have started the solo mining with 2.2M for verifying,
And, i am expecting  9~12 blocks for 24 hours

[bee7]

Thanks, it's really depend on lucky.

Your wallet conf file is fine. But you said nothing what cards do you have and what parameters you use with cgminer. Just that you set intensity to 17 for all of them does not say much.

5.6M 24h solo 14 blocks. is that different?

Thanks.
Not just GRA, I found that solo mining get less blocks than I found in pool, that's strange.

For the one block, it takes 4 hours with 1.4Mh

It means 17% of error (base on luck/no luck) per day
It means 2.5% of error per week

Anyway,  14 blocks with 5.6M, it is pretty low number, i think, should be around 22~28, i guess
Clearly, something wrong

2 cards, 7850 1G; 2 cards, 7850 2G, total set is as below, I have tested many coin, the same parameter, in pool I got more blocks than I solo, I confused solo mining need any other parameter? Thanks a lot for your reply.

Yes, I know. Unfortunately, I have not very fast connection, so I have many blocks orphaned. But still I find the ratio reasonable. My rig is already paid off earlier so now I spend only electricity. As this coin is young and not having so many problems as cats e.t.c I decided to stick with it and lately even joined bosian in his development efforts as you know.

Unfortunately, I can't be helpful in your case as I have no experience with these. I have a set of 7950, 7970 and one R9-290

In the forkpool, they got 203 blocks in the last 24 hours, more than 4/5, but the pool hashrate not more than 35M(I checked it some times in the last 24 hours), I think solo hashrate is abusolute more than 15M, that's strange, solo mining really got less blocks.

coinmarketcap!

 

Yes nice we are on coinmarketcap, we have plenty space to grow

Graincoin could use a little love on reddit.  Someone was good enough to make http://www.reddit.com/r/Graincoin/ lets use it.

A good pow/pos coin... not many new such coins

I am not sure about that, becasuse of I didn't tracked forkfool, anyway, on the coin reward report from bee7, I guess they have got 168 blocks
anyway, I am mining from 19:00PM EST (USA), and, I have to check tomorrow, and I will post my solo mining report for the review,
