I think, working well.

the current diff is moving betwen 0.6~0.9 (just sometime under 0.6 and over 1.0).
so, you will get message "Network diff set to 0"

Block time of this coin is 30 seconds,
so, you will get "New block detected on network" message around every 30 seconds

This coin is adjusting the diff every block and changing diff by every block
so, you will get both messages every time.

I'm on 290Khash/sec.

Worth solo mining? Or just join a pool?

solo for sure, you might hit a 1% block and earn a week or so mining in one block.

Then again I have never hit a 1% block. So better not get his hopes up too much.

Hmmm this does not look right to me, the diff should not set to 0. Are you sure you wallet is sync'ed up?

The network diff reported by cgminer varies depending on the version.  The older ones like 3.6.6 would say the target share difficulty, i.e. 4.5k so that means if we find a share that is higher than 4.5k, it is a solution to the block.  The newer 3.7.2 only reports the network difficulty, i.e. 0 for anything from 0.0000 to 0.9999 - doesn't show it as a share difficulty.  Personally I prefer to know the target share difficulty.

Yo guys.
I'm getting rejected with "this worker was banned temporarily" in cgminer window. Mining on gra.forkpool.com.
Restarted, everything seems fine for now.
What was that?

You were probably generating too many bad shares - the pool would have requested work restarts, and if that didn't help - would have blocked you for a time.  Check the HW: number for hardware errors.  If the number is higher than 0, you are sending out bad shares.  As long as the number is relatively low, you are ok, but if it is a significant proportion of Accepts - then you have problems with your cgminer configuration.

I'm on 290Khash/sec.

Worth solo mining? Or just join a pool?

The network hash rate right now is about 87MH, so you 290kH is only 0.3% of the network.  If all things were random, it means that you have 0.3% chance of solving a block, or 3 blocks in a thousand blocks or 1 in 330 or so.  The current block rate is about 3 per minute so theoretically you could get a block every couple of hours.  In reality though, your hashrate is very low, so you might not get a block even if you mined for 5-6 hours.  I would solo-mine if I can get 10% of the network or more.

The suggestions of joining a pool are great - you will get consistent earnings as opposed to the chance or scoring the big one that might not come.  Again - in the pool you are only getting a percentage of the earnings, but you are getting that percentage.

[Edit]  Also, choice of a pool makes a difference - a pool with very little percentage of the network will also earn very little - I usually go with the second largest pool if there were more than two pools, otherwise go with the largest pool.

In CGMiner 3.7.2, just show the integer part of Diff.
If Diff is 0.9999999.. It will shows as 0, and if 1.000000000001 it will shows as 1
old versions show the network hashrate(via bitcoin). Actually, BFGminer also show similar screen.

[JL0z]

Ok, then perhaps pool mining would be best. Any recommendations of which pool I should use?

There are two pools that I know of

gra.forkpool.com
gra.livechains.net

Basically between the two of them (and a few solo miners) they will get most of the blocks.  The larger pool will get more blocks, but then it is shared amongst the miners.  The smaller pool will get less blocks, but you get more of each block, so in the end - it really balances out more or less.  We don't really want a pool to get too large because then it is harder for smaller pools to get blocks and it can happen that people then end up all in one pool - which we don't want to happen, but it is your choice.  I am with forkpool which was the first pool to go live.  Livechains came along and I understand is doing well and the fee is less.  You can always register with both and look at both pool statistics and decide which one or both you want to mine with.  Most miners do similarly and switch pools from time to time.

Thank you. I'll join one of them tonight and see how I get on. Will compare them and see which pans out best for me. Much appreciated.

Pool estimates based on pool size.

Network hash rate = 100MH

Pool1 = 60MH   Pool2 = 40MH
Block % = 60   Block % = 40

Over 100 Blocks at say 1000 GRA per block

Pool1 = 60,000   Pool2 = 40,000

Your share at 0.3MH

60,000*0.3/60   40,000*0.3/40
=300GRA/100Blk   =300GRA/100Blk

This is just to show what I mean that it balances out in the end.  Your hashrate contributes to the pool and earns a percentage of the pool earnings.  With a larger pool you earn a smaller percentage of more blocks.  The smaller pool earns a larger percentage of less blocks.  So in the end...it is more or less the same.

Even with bonus blocks, the pools generally get a similar proportion.

Now the above is generally when the pools are similar size, not too lopsided.  What can happen if we get say Pool1 = 90%, and pool2 = 10% is that Pool1 gets more than 90% of the blocks, like 92-95%.  It happens because the pool that gets the block starts working on the next block before the other pool knows that the previous block has been found.  I know that this is really only seconds - but seconds count with block times like 30 seconds.  I find that sometimes a pool will get a run of blocks before the other pool catches up and vice-versa.

I'm on 290Khash/sec.

Worth solo mining? Or just join a pool?

solo for sure, you might hit a 1% block and earn a week or so mining in one block.

Then again I have never hit a 1% block. So better not get his hopes up too much. 

Good luck!

[JL0z]

Of course some pools are luckier, in that they seem to get more than their expected proportion.  This is occasionally due to a single large miner, i.e. a miner that is 20MH in a pool where the other pool has a largest miner of 10MH, can sometimes swing the luck more to that pool.  But anyway, for two pools - it really doesn't matter.  For three pools or more - as I mentioned before, I would usually go with the second largest as long as it has a reasonable percentage, >20% of the hashrate.  But that is my opinion.

[cryptomining]

Solo'ing is a waste of time. Join a pool and get paid for all your work.

At these reasonable diffs over time at worst its the same at best solo wins, lots of nodes make a better network, and solo is just more fun when the alert pops up and you hit a block.

I'll leave solo mining until I've upgraded to my new card. Something around 800 K/hash would be more reasonable for solo mining. 

[Lorren]

Oh my goodness did I get lucky! 

I decided to try solo mining a little while ago... just to give it a try.  Since my computer is running around a couple hundred Kh/s, I wasn't expecting to see anything for hours... I didn't even know if I had my miner set up correctly.  I think my account over at otakasamaaa's Graincoin Pool must have been deleted or something; even though I had an account over there, I couldn't log in.  Turns out that reregistering with the same user name and password worked.

So while I was registering at the pool over there... I found a block!  I had to have been mining for only about 10-15 minutes or so.  I think I got more GRA in 15 minutes than I have in the rest of the time that I spent mining... other than giveaways, LOL.

Anyhow... regarding earlier discussions here... I don't mind that GRA isn't on an exchange yet... the longer that this train keeps chugging along at low difficulty, the more of a chance that us little miners have to get some.  I would have very little chance finding a block in one of the highly hyped up coins like MOON or DOGE.  If this coin slowly grows and gains interest, perhaps there is less of a chance of this coin being pumped and dumped.
