Not only between 500 KH & 800 KH, we're also having these issues on Pool42.
We may have a little more blocks per day, but our situation definitely degraded as we used to have between 8 & 15 blocks per day
But 15 blocks of around 0.5 XMG is much less than one block of 40 XMG.
Of course, though back then it used to be in average blocks of 8.
And maybe shall I recall you that it was the maintenance mode where rewards (and therefore benefits) were drastically brought down compared to before.
Now, if we look back, 15 blocks at 8 XMG is worth 120 per day while here we have 80 per day.
We actually expected the income of our miners to be four times above what it used to be during maintenance...
That is true, of course.
But compared to not finding any blocks at all is just burning clouds.
That's right. It sounds like this update weakened small polls pushing people to go to large pools.
There are a few raised concern regarding the new wallet, but I'll keep a rely to all here.
The big rewards does sound coming out the way that appears uncommon. Following my prior post about overhash things, additionally I do need to reassure we're going the right direction. We need a reasonable hashrate estimate, and the PoW / PoS rule has been going the way affecting how difficulty is being adjusted. I'll need a better handling, or put it the way being trivial to the block time.
At this moment I wouldn't agree with the conclusion based on what we thought; there are no special things that rule out the smaller pools except this first thing came out with the big rewards. Anyways, let me give updates on the correct network hashrate calculation and how to take actions on correcting the block reward likely in this weekend (need get my work stuffs sorted out as the first high priority).
Here what we have regarding the mining; the pools with higher hashrate have the higher probability of finding blocks, or can find more blocks than the smaller scale pools; those blocks found include those accepted and rejected (PoW general rule). This means when smaller pool gets blocks rejected; the big pools should get even more blocks rejected; doesn't make sense the other way around.
There are causes like the big miners coming along that would lead to difficulties in finding blocks; this can be reasonable since the block reward gets high, and also we get back on normal functions with more open pools (like zpool is up but not in the maintenance mode).
Edit: Just spotted the block rewards drop down to ~2 XMG; will check on the things anyways. I also suggest pools monitor the blocks to get some average values over days. Feel free to post here what you get.
