Thanks MPH, for clarifying. I did assume it was very unlikely that an operator for many pools would risk it all to skim off the top. Happy to understand it now. You shall continue to receive my hash!
Hi
This is mining pool hub.Sorry for late reply. I didn't notice these discussions until now.
I didn't steal jackpotcoin. I promise, I can say with my name, my parent's name, and my god's name.
I don't understand you guys just saying that I'm a thief, scam thing.Actually, these days my server was suffering with performance issue with jackpotcoin.
I was considering to optimize jackpotcoin wallet.dat, since it has grown upto 200MB.
This big wallet makes my whole pool to get slow, so I was busy with solving this kind of it.
Didn't know even discussing this.
I actually don't know why you got less than you expected.
1. Did you check the block finding stats?http://jackpotcoin.miningpoolhub.com/index.php?page=statistics&action=blocksWe are having 144.18% for Last 24 Hours. It means, 44% hashes were gone to air than ideal expectation.
As jackpotcoin wallet's are increasing, this stat became worse and worse. It was good at launching, 90% or so.
PoS block time is about 20 seconds, we have to reset all work when we receive new block info and spread it to all miners.
This overhead is not small. As p2p network don't guarantee block notification's to be done in few seconds, our pool may get new PoS block even two blocks after.
As you can see at cloudminer, their percentage is high too.
To say about p2p propagation delay, refer
http://drk.poolhash.org/poolhash.html"tsdiff" is the seconds delayed from what they found the block and the time the other nodes get the new block info.
This is not small. 10 to 32, even 112 seconds of delay occurs. It really makes problem with 20 seconds block time.
To compare with Maxcoin, which has 30 seconds block time's stat is about 120%, and other Darkcoin, which has 2.5 minute block time's stats is about 100% for All Time. You get it? Short block time makes PoW not run as ideal.
This is why some solo miners getting many orphaned blocks than other coins. His wallet need to connect to pool or big solo miners.
Even worse thing is, as more individual wallets are running, our pool need to collect new block info from solo mining, solo PoS wallets.
Pool wallets are different than other solo mining wallets, since we increase network connection count much more.
I modify MAX_OUTBOUND_CONNECTION in net.cpp and compile. Do solo miners do this?
It improves transactions, block info propagation faster. I recommend you to change this value for coin environment.
Other coin minings were Pool vs Pool, but this jackpotcoin is somewhat different. Very short block time, Many solo mining wallets.
This is why our percentage stat is getting worse time by time.
I didn't modify percentage values by my own. It shows the real value.
Check this stat with other coins, or other jackpotcoin pools. Last 24 Hours stat number can go up and down like roller coaster, see All Time Percentage.
2. Net hash decreased after jackpot found.As jackpotcoin wallet's net hash doesn't work for PoW only, it shows wrong numbers. I know that dev team aware this problem.
I will tell you how to estimate the net hash in this situation.
http://jackpotcoin.miningpoolhub.com/index.php?page=statistics&action=blocksSee the Last 24 Hours row, last column. Rate Est.
It is just simple calculation that block should be found 720 a day, and this pool found 312 last 24 hours.
It is now 43.47%, so we can estimate the net hash by multiplying about x2.3 to pool hash.
Do you get it? Our pool hash dropped, and whole net hash dropped too.
It increases when jackpot value rises up, and it drops after jackpot.
I can say that this is why you got more coins these days.
3. You can check how many blocks you found and you generated at Block finder page.Calculate it and compare with the Credit you earned in Transaction page.
It can vary very much, but I can say that high hashpower user tend to earn more than they generated coins on PROP rule.
I changed PROP to PPLNS few weeks ago, so this change may affected some high hashpower users.
This estimation is not reliable, since luck, probability needs much more data.
There might some people got more blocks than expected, and less blocks than expected.
I don't control it. Just MPOS distribute it by calculating their shares.
Don't blame me if you got less coins than you generated. It means that your GPU was lucky than other miners.
4. Solo mining don't have overhead of network latency from pool to miners.It may increase performance, but not sure how much it will.
I think this time is about 2~3 seconds to propagate to all miners.
2~3 seconds for 20 block time is 10%. It's not small in this case.
This latency affects "Rejected rate", you would aware that this is rather important.
Again, I'm saying that 20 seconds block time makes weird things comparing to other coins.
You may earn more coins with solo mining time to time. You'd better try solo mining if you have high hash power.
I didn't test or simulate, but just want to say there is overhead on pool and this overhead may be bigger problem than other coins due to 20 seconds block time.
5. Are you sure you didn't calculate PoS mining?They are all written as "mined", so you need to separate them from PoW.
Summary.The right method to compare pooled mining and solo mining is to separate GPU half and half and run it simultaneously at same time.
And it needs more than 3 days, since PPLNS payout needs time to boot up.
I'm running other coins also, didn't get any complain like this before.
Jackpotcoin is not my first coin pool. I had run many coins with providing trust and fast feedback.
I like jackpotcoin, but why do I scam with only jackpotcoin?
I tried my best to offer good service.
I tried to listen to many miners saying and changed jackpot distribution rule to satisfy miners. I even opened poll since I heard many complains about the rule.
What do I have to do then?
Complaints about jackpot rule and blaming as I'm a thief..
Optimization and lowering network latency needs more work to do but don't blame me as I stole coins. I didn't. Really.
