NovaBlock, The Most Profitable Mining Pool

Shows their blocks.

Looks like so far in October:

1st - 1 block
2nd - 0 blocks
3rd - 0 blocks
4th - 2 blocks
5th - 1 block

Looking at the period where diff was 11.891T, 9/13 to 9/26, the site shows that they found 37 blocks. 700PH for this period should average 1.18 blocks per day, or about 15.4 blocks for the 13 day period. If I did my calculation correct, it would be about 1 in 500,000 chance of hitting 37 blocks in that period when you'd expect 15.4 on average. So it definitely looks like something is wrong. The hashrate would need to be closer to 1700PH to get this number.

I looked through a bunch of those blocks and the block rewards all go to the same address, 3Bmb9Jig8A5kHdDSxvDZ6eryj3AXd3swuJ. So It appears the blocks were mined by the same pool.

Maybe they have ~1000PH of their own that they are not showing in their stats.

Yeah that is the most likely explanation.  Which would mean  they are very well funded. So they should pay out consistently. Time will tell.

so seems my dashboard is stuck on 9-29 , and wont switch over to oct ,  anyone else have this

activity, i would like to see the profitability graphs showing some details , but its stuck on  9-29 

NOVABLOCK prob needs to look into the css or code on the site and make sure its correct in keeping

up with the current time ect .


Thanks

Hi Freemine-001010,

I will have the technical team look into it. I apologize for the delays as we are preparing to head to Germany for the WDMS Conference. Any lost hashrate or rewards we will make up to you if we can verify the issue was on our end, so don't worry.

I'll take note of your suggestion and tell the technical team so this does not occur again.

What is your roadmap for fees after 2000PH? Also, would you consider adding a PPLNS payout at a lower fee?

Hi wndsnb,

We expect that our fees will go back to 3.5% after the initial 2000 PH has been reached. Everyone that joins the pool prior to the 2000 PH mark will keep the 2.5% fee.

At the current moment we are not thinking of adding a PPLNS payout option but I will discuss with the team to see if it would be valuable to add.

also could you introduce a auto refresh feature on the workers dashboard page, as i have to refresh it manually to see the current hash rate of my workers...

Mine auto-refreshes in what seems like 30 second increments.

and a request on the pool stats could you put a marker on the graph / timeline to denote when blocks are found...

I second this.

Thank you for your suggestions, we will look into adding the marker on the graph as soon as possible for further clarity to our clients

Hi all,

All of the hashrate shown on the pool is accurate. While I cannot comment on how lucky we were during this period to find a large amount of blocks, I can confirm that we do not have any hidden hashrate shown. I do know that during the initial stages of release, we have always kept steady around 700 PH and that when we were initially put onto btc.com list (2 - 3 weeks after our start date) we found more blocks than expected and that showed our hashrate to be around 1500 - 1700 PH. This number has since been coming down to accurately represent our hashrate.

We need to provide accurate stats so our investors understand how well we are doing and how much hashrate we have accurately. The goal of 2000 PH is one set by our investor and so by hiding 1000 PH it provides us with no benefit and makes us look like we are further from our actual goal. In addition to this, it also makes us look bad to our investors and clients that are on the pool. I can say that the majority of the hashrate is not ours.

For clarity sake, we are adding another 100 PH to the pool around the end of October,.

Thank you all for your concerns and if you have any questions please don't hesitate to ask. We'll try to answer all enquiries in a timely manner.

Please note that there may be a small delay in responses due to us attending the Germany conference.

Any probability/Possion distribution gurus want to verify my #s?

It gets way way way less likely looking further back.

For the time when difficulty was 10.772T the pool found 47 blocks when 16.9 were expected, and during the 10.183T difficulty period it found 44 blocks when the expected was 19.2. So include the 11.891T diff period where the pool found 37 blocks when the expected was 15.4 and you end up with a total of 128 blocks found when the average expected blocks found should have been 51.5. The probability of finding 128 or more blocks when the expected on average is 51.5 is 1.998E-19, so basically 0.

I wasn't suggesting there would have been anything shady about having your own 1000PH that wasn't being reported on the website. It would have made sense if your goal was to get 2000PH of external hashrate.

I guess they are the world's luckiest pool

[Freemine-001010]

Pool Name   NovaBlock
Hashrate   606.66 PH/s
Network Share   0.67%
    Last 6 Months   All Time
Block Count   81   81
Rank   19 / 27   65 / 93
Share of Blocks   81 / 27,242 = 0.30 %   81 / 598,031 = 0.01 %

btc.com has us at 81 blocks total

looks like their block explorer is off

[philipma1957]

81 vs 150 is a big error and drops the luck down to simply good vs unreal.

[MoparMiningLLC]

So the block history and btc earned reflected on novablocks history page is wrong? Who found the blocks listed on the site then?

anyone compare where the payments went that btc.com shows for the pool vs the ones that btc.com shows as not novablocks? I may do this when I get home.

Hard to do much of a review or in depth comparison if the data being provided is inaccurate.

Yeah you can show the diff and what a 100% payout of 12.5 coins is.
You can show viabtc payouts
You can show nova payouts.

But if block reporting is wrong is is hard to show what is lost in trans actions. Oh well

[Freemine-001010]

yea now that im using the setup, i can see some inconsistency's  

after i commented on the block explorer @novapool it started updating with the 2 blocks found oct-4  

Also @novapool my weekly report is still not updating , so what ever you did to the explorer code needs to be
applied to the area or module that controls the current time relative to the graphs .
Lett's get this stuff worked out-

Thanks

Have you tried looking at some of these stats through the App? I'm away and can't check against the website to confirm any issues. I would be interested to see if you have the same errors across both platforms.
In regards to the reviews they are only a snapshot in time. With the payout structure of Novapps+ the blocks they find and transactions do not matter, as they stated it's a set estimated transaction reward based applied based on the amount of blocks expected, not actual found.

I did inquire as to how often it adjusts, if ever. If it does adjust could be based on average of last "x" blocks found or something similar. This would  then affect payouts.

I do agree though accurate pool stats are much more proffesional. That is why they have people reviewing and are actually responding and working to fix issues which is nice.

[Freemine-001010]

yea , i just wanted to chance to review it for the 0% , but alas im not worthy 

but ill do my best help out, REALLY WANT A USA POOL IN THE TOP 3 , China shouldn't have all the fun 

[wndsnb]

... btc.com has us at 81 blocks total

looks like their block explorer is off.

btc.com only started monitoring them on 9/6, but the history on novablock.com goes back to 8/14. The period when diff was 10.183T started on 8/18.

https://novablock.com/space/block

The blocks also seem to match up with rewards going into their btc address starting on 8/15, https://www.blockchain.com/btc/address/3Bmb9Jig8A5kHdDSxvDZ6eryj3AXd3swuJ?offset=250&filter=6.

[MoparMiningLLC]

but my point is this - how many blocks of they actually found? 50? 60? 150? if it really is 150, the set amount should be going up, not down. its dropped almost 6% in two weeks. If they are doing this well, I would think it would be higher but I do understand that with PPS it is just the set amount

According to their site they've found a total of 154 blocks since 8/14. The rewards for the last 151 of those blocks go into the same btc address.

I have no idea how they calculate their payouts, but the point of PPS is that pool luck does not affect you. So I'd expect that if the pool got super lucky it would not have an impact on your earnings, the same is true if they are super unlucky. I'm not really sure what the meaning of "fee" is for PPS, and it is probably different for every PPS pool.

[MoparMiningLLC]

exactly, I get the whole PPS thing - but how they hell can their average be what it is? 154 blocks with a 700 ph/s pool is astronomical good luck - as everyone else is also pointing out.

Pay Per Share payouts are calculated per each difficulty period.  So PPS Pools payout less each difficulty period when difficulty increases or more if difficulty decreases, which is very rare.  PPS does not change each day.

So if the last difficulty period increased by 6% then that would account for the 6% decrease in payout.  Difficulty gets recalculated approximately every two weeks.

correct - was trying to be sarcastic, it failed - i will remove it.

By the way, I thought the first rule of BTC was to never share how much BTC you own
...

If you want to run a public pool, then hiding information from your members that determines if the pool will fail or not, means they shouldn't mine here ...


As for block numbers and people making random calculations ... the calculation to determine the probability of the pool results is calculated using the Erlang CDF
https://en.wikipedia.org/wiki/Erlang_distribution#Cumulative_distribution_function_(CDF)

That's something I of course show on my site for block histories and ranges

No other pool seems to have anyone with much of an understanding of the statistics of the Poisson Distribution that governs block finding
