check the blocks using block explorer,
it is not generated coin, I am saying about the transaction,

500M has pre-mined/generated by developer
and, 140M has been generated,

the transaction has been made to send 5k~20k coines to somebody,
my question, WHO has 192M coins

Is it transactions from ORIGINAL DEVELOPER ??

Ok, thank you for your kindly advice,
I have. Remove the color and size.
But,  i have so curious about that transaction, because of eventually happen at once after block chain has been recovered. And, that transaction has been relayed thru the addresses on drop action,
Anyway, i feel it is my misunderstand, and I and to say "sorry for making annoy" and "thank you for your kindly advice"

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.

 

How long are they held? How often does it happen and how do I stop it? And what if I need the coins right away?

Mine has only ever taken a couple of minutes and then back to normal. If u encrypt your wallet it will stop pos generating until you unlock for minting

now that there is some data to look at bosian is looking into it.

not sure when we should expect any info on it, as everything seems to be working right now, it appears the problem only happens sometimes. may be difficult to track down the cause, or it may be that everything is functioning right and somehow the diff is sposed to go that high sometimes...? anyways bosian will figure it out and let us know, or later on it will happen again and maybe some cause can be established.

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.

No Jollyburner. This is not a problem, look at my explanation above.





The PoS blocks will be held for the same amount of time as minted PoW blocks, for Grain it is 50 confirmations (i.e. 50 block times). See OP for the coin spec:

How often the PoS blocks generated? It depends on how long you hold your coins. Typically, after 10-15 days holding, the pos blocks will be generated.

If you don't want PoS block (I doubt why you don't want it, as it gives you free coins), the easiest way is to encrypt your wallet with paraphrase (don't forget the paraphrase, or you will lose the wallet), if the wallet is locked, the pos will not be generated.

Another way to avoid pos blocks is to transfer the amount to another wallet, then transfer back. By transferring, you lost all the coin-days you accumulated. You basically reset the coin-day and it will restart from zero.


We welcome all your questions. Please, ask them in a constructive way, so we keep a good environment in this community. We are more than happy to answer all your questions.

My wallet says - 'Minting is suspended due to locked wallet'. What does that mean?

Meaning your wallet is locked so no pos blocks will be generated. You need to unlock the wallet for pos to be generated.

See, for example, here:

The PoW diff adjusting algorithm works on the last real block time, it is the same as PPCoin diff adjusting algorithm (almost all the PoW/PoS coins use the same algorithm). This algorithm limits the max adjustment to about 2 or 1/2 each time (depends on some detailed parameters). So sometimes people (especially those with high hashrate rig) try to profit from it. What they do is to put in all their hashpower (could be close to 50% of the network hash, if not too many people are mining it at that time), get one block quickly (maybe in 10 sec instead of the average 30 sec), push the diff to about X2 for the next block, then move their rig or rigs to another coin, now the diff is high for the rest of the people, it may take say 2-3 mins to get a block, and because 2-3 mins >> 30 sec, the diff will be halved for the following block, then these guys jump back in and get another block, etc. This way, they enjoy 10 sec a block instead of the average 30. Sometimes they do that also intending to jam the coin, but with PPCoin algorithm, they can't jam it (I saw some time ago they jammed infinitecoin this way, then IFC moved to PPCoin algorithm for diff adjusting, and everything is smooth since then).

Only when enough people are mining, that a single or a group of people with big rig can no longer do this, because of the total hashpower is much higher than theirs.
