What is this?   This is democracy!  |

Wow, I opened my client, got 9 PoS blocks in 15 min. and the PoW difficulty jumps to 6  Its like: What, you wanna PoW mine some Grain? Well f*** you, I am opening my client.  Bosian: Can't you increase the minimum coin-holding time needed to generate PoS blocks? |

Is there a chatbox anywhere for Graincoin?
btw, did the net hashrate just jump to 500MH/s?
Well its at 390mh/s! This is not the work a single miner hashing this power just to stock some GRA! Could it be GRA finally caught Chinese attention? YES? MAYBE? HOW I LOVE THE SPECULATION  There is no 390mh/s hashrate on Grain, the network only sees it due the high amount of PoS blocks in a short time. It is not an issues from PoS And, QT display the wrong network hash rate, Anyway, we need to check after stabled Read this: It's good to see that everyone is waiting for the returning of PoS block generations. I hope everything will be smooth when we pass through the switchover block at 92000 in a day or two (pretty sure it will, as it worked fine in my tests). Now I want to give you an overview of the issues with PoW/PoS so we will have a realistic expectations on the PoS. From my experiences and my observations of many other PoW/PoS coins, the PoW/PoS coins are far less stable than the PoW only coins. The commonly observed problems are: (1). PoW gets jammed (happened to many coins). Many fixed the issue by forking a new blockchain (including GRA), some did not bother to fix (or dev vanished?), like ADT and COL are still in PoS only mode. (2). PoS stopped, like what happened to Grain, this is due to the out of sequence in time stamps. (3). Lots of PoS generation affecting PoW block generation. The issue (3) can be an annoying one. According to current algorithm, the PoW block time can be extended up to 12X the normal time, if there are a lot PoS generated in-between. This is a normal behavior to maintain the overall block time. And we don't expect PoS always generate a lot all the time (it's controlled by its own diff adjusting). Another possible issue with a lot PoS generation is that it might affect PoW diff, and cause orphans (and I still need to check the code to see why - my understanding is that the two diffs are separated). I saw this issue occurred with Lucky7Coin end of last year, it caused a lot of issues in mining (virtually all the mining pools are stopped as 90% are orphans), and most blocks generated were PoS blocks, with some PoW in-between (the PoW generated time increased between 2X to 12X). The problem is gone now after the PoS generation subsides in Lucky7coin.The Grain is based on Lucky7Coin code (mainly to use its superblock generation algorithm), which in turn based on Novacoin/PPCoin. We adjusted many parameters and hopefully the same issue will not occur here. We also have all the fixes from PoW/PoS (like the fix from Balthazar on self-forking). For now we still allow the max PoW generation block time be 12X the normal one if needed. We could change it to less multiples such as 3X used (fixed by a patch in) Novacoin codebase, so it could make the mining of PoW less disruptive. Anyway, just want the community knows the status of PoW/PoS coin in general, and let's hope the Grain will work great |

PPC has also wrong block times.  |

Its a good pool. My miner was very lucky on it and has generated 479,343 coins, but I got only 83642 coins payout, because of the low hashrate of 350 khash/s, |

Can I have a question ?
While mining why the difficulty has been changing continuously from 0 ~ 8, and keep looping, my hash rate is around 650k. But,it has been stabled today.
mkimid, there are two difficulties here: PoW difficulty and PoS difficulty. PoS diff is very low (close to zero - so that everyone can generate PoS blocks from his client), this is by design. PoW diff, is what you see when you mine with cgminer, for example. PoW diff is very consistent, varies from 0.3 to 0.6, or whatever the range. So when you look at the diff, what you care about is the PoW diff. Look at the block explorer, and look only the diffs for the PoW blocks, you will see they are pretty consistent, and varies smoothly according to the real block time of the previous block. http://coinblockchain.com/grain/Thank your for your explaination, Actually, i have experienced last saturday and sunday, If you see the blocks (57814, 57665, 56993, ..) and near by, Relatively, higher number of diff. Started with diff 0 (PoW, cgminer), it is increaed to 6 ~ 8 And than, return to some number such as 3-4 And increased again to 6-7 And than, return to some number ... I just felt kind of something is happen, and it is not smooth .. Anyway, today, it is much better than before,
Maybe some hidden factors are removed/overcomed/fixed
http://coinblockchain.com/grain/block/000000000c1c41158bc88e7e5a3d22c3f6aa4e33a9d716da2c5da69258e27479Similar with before, Block #59289, 59288 :: checked the time stamp Maybe the people wake up and start their Grain coin client and this generates a shitload of PoS block and drives the PoW difficulty so high.  You can't look at one block. You need to look at an interval of 1-2 days and count the average block time for PoW. It should be pretty close to the target block time. Ok, but do you agree, that the amount of PoS blocks affects the difficulty of PoW blocks? |

mkimid, I see some pos coins generated... you better learn what is pos before posting stupid things like this in big red.
Aren't block 58809 and 58808 PoW blocks? |

Hey Bosian, how about you make a new givaway to increase the coins popularity?
|
|
|
|
|
Could this problem be solved by increasing the PoS difficulty?

Jollyburner, I think I would have to agree with you. I had a look at blocks from 56071 onwards to check the addresses that payments were going to:
56071 9RasWHQWcNfcS86uk4pHC3v5KMafFyYUck
56072 9RasWHQWcNfcS86uk4pHC3v5KMafFyYUck
56073 9RasWHQWcNfcS86uk4pHC3v5KMafFyYUck
56074 9RasWHQWcNfcS86uk4pHC3v5KMafFyYUck
56075 9RasWHQWcNfcS86uk4pHC3v5KMafFyYUck
56076 9EcmNqQmiEbo5G4s2e91dzGdL9KRjenrQ9
56077 9AJ5YhCPkTKSXNx9fFobmkayp2cBUqFUNZ
56078 9RasWHQWcNfcS86uk4pHC3v5KMafFyYUck
56079 9RasWHQWcNfcS86uk4pHC3v5KMafFyYUck
56080 9RasWHQWcNfcS86uk4pHC3v5KMafFyYUck
56081 9StWjUHMHt3FfQXMKxtcDNRr3h26cKQKtQ =livechains
56082 9T5EUuj1f24jRUWfbKwrRtWbMVzr5UZF3A
56083 9T5EUuj1f24jRUWfbKwrRtWbMVzr5UZF3A
56084 9RasWHQWcNfcS86uk4pHC3v5KMafFyYUck
56085 97mHyuMsZC3RyU9p3JiX5xyDpYXDZZUFdj =forkpool
56086 9RasWHQWcNfcS86uk4pHC3v5KMafFyYUck
56087 9RasWHQWcNfcS86uk4pHC3v5KMafFyYUck
56088 9RasWHQWcNfcS86uk4pHC3v5KMafFyYUck
56089 9RasWHQWcNfcS86uk4pHC3v5KMafFyYUck

56120 9EX5G97HZMgZaTLdonGzNvs3ANDpBpiV47 =other_miner
Most of the payments are going to 9RasWHQWcNfcS86uk4pHC3v5KMafFyYUck which I guess is a PoS recipient. Only 6 mined blocks in that lot of 50. I gave up recording the addresses and ended up just looking for mined blocks.
Ok, I now understand the low difficulty. It's the PoS difficulty.  |

Who can recommend a nice pool, less reject, thanks~
gra.forkpool.com has been working well. They lowered the pool fee from 5% to 3%. |

I just love Grain.  |

Yey, I just received 20K Grain!
Many thanks!

They are making a Graincoin pool after they have finished making a Moon Coin Pool Very nice! |
