See, with NH;  they are trying to solve a block with your transaction;  so a different hash all together.  Theres no way for a renter to withhold blocks like that...   you can see the live submissions/hashrate coming through the solo pool.  I don't see that being faked at all.... unless the hash renter feeds garbage data to the pool (I would assume the pool would invalidate bad work?)


My one recommendation to people going for rented hash:

Its smarter and more statistically probable if you rent as much hash as possible and run it at once.

More workers working on the same block == greater chance of solving _your_ block in a given amount of time.

If you just space out the hash in smaller amounts over time;  you have less hash to find that block in a given time and it is somewhat wasteful.



In the same sense that pointing two antminers at two different BTC payout addresses, will both have the same probability of finding a block;  whereas if they are both mining to the same address, they stand twice the chance as find a block as when they are working independent.

I hope people grasp this idea.....

The more hash you cram in that "10 min" gives you a higher actual probability of finding a block.

We've talked about the dangers of rented hash many times before. The person who sells you the hash makes money whether their hardware solves blocks or not and if they're a big player they stand to gain by holding back diff from rising. The person who rents the hash assumes all the risk. In the earlier days on this pool the odds seemed to suggest that all the PH sized rentals were suspicious in they never found blocks while the hundreds of TH sized rentals did. I gave people warnings about this at regular intervals. However lately the rate at which PH sized rentals are finding blocks is averaging out to 100% luck so I don't see a problem at the moment, and it could well have been bad luck earlier on. This could change at any time though and there is no way to confirm this. And before you ask if there's a way to check whether rental hash is withholding blocks - no there is no way.
The BEST thing that would be helpful is if the rental service (nicehash, MRR etc) was to report the total shares found by each rental and the number of blocks found by that rental to confirm that it is finding blocks. None of them do that as far as I'm aware.

This is 100% incorrect.  A miner can easily submit all found shares except shares that are greater than the network diff.



This is also wrong.  See ck posts above.  The only time working faster matters is to beat a difficulty change.  There is the same probability in finding a valid block with 1000TH for 1 hour as there is with 100TH for 10 hours.

Theoretically - would it be possible for a pool to send a miner the most recently solved blocks template immediately before the block change notification?  In this situation the miner should send back the solved block, then the pool could then discard it and continue sending valid work.  This could be a proof to see if blocks truly are being withheld.

I realize in this scenario some hash time would be wasted on an old block.

I hope you can grasp the idea as it has been pointed out a few times already that you are wrong on just about everything you stated.  Your points are a great summary of the common misconceptions almost all people have about how solving a block works.

Thanks.

We are due for one.

I just found this talk.  I have 55th/s with a pool right now.  Is there a chance that it would be more profitable for me to mine solo rather than with a pool?  I currently make $3700 a month with an electric bill of $1000.  Does solo provide a better income?

Do you know how many blocks you solved during each difficulty?

I do not know how many blocks I solved during each difficulty.  I only know what the overall pool solves and I get a portion based on my Hash rate.
