Maybe we'll stop having a block per second now.

Looking at the information panel of the qt help window, I just counted 10 blocks in 40 seconds Sad

I'm sure it's been looked at already, but I wonder whether the code doesn't even attempt to find primes with chain length of 7 now.  I hope it skips them out otherwise it's doing unccessary work.

I can confim, that both my Windows and my Linux versions show an approximate 30 % decreased PPS rate.

Referring to Sunny King's paper (and hoping that I understood that part Wink ) a difficulty increase from 7-something to >=8 means that the prime chain length has been incremented by 1.

Although I don't know where the PPS rate is derived from, I assume the drop of the rate has to do with the difficulty increase to 8. But I'm not skilled enough in programming to find the place in the source code where the PPS rate is generated and what variables are taken into account...

quite the drop alright.

I think that can only be a good thing.  I'm glad for getting more blocks in the last 12 hours with this version, but the effect on the price is obvious - 30%+ drop

if its across the board its fine nothing really changes... its like we were all running fast now we all run 30-40% slower

I haven't looked at the code but I think that the diff is controlled by the length of the primes.  Since we've just hit a new whole number on the diff, I suspect the code now needs to search a significantly larger number of primes.  I'm actually seeing about 30-40% drop now Sad

URGENT!!!!!

Has anyone else just seen a 25% drop in PPS?  I'm getting this on every single machine/VPS I have running.  Happened in the last 30 mins.  Perhaps due to the >8.0 diff increase?

Yes pps dropped even more than 25% on my rigs.

Jumping to difficulty 8 makes the mining algorithm do more work. That's why PPS numbers are dropping. We'll have to see what happens to block rate.

When difficulty increases from 7 to 8, does it mean no one is going to mine length=7 chains?

hmm both my windows and Linux box primespersec just dropped from ~4000 to ~2500

and my core duo two laptop went from 1000 to 725

ok negative on the new mikaelh2 build it's generating a large # of orphans


The orphan rate on the network is expected to stay relatively high for the next couple of days, while difficulty plays catchup to the growth of mining power on the network.

This phenomenon is a one-off occurrence, could last another week. It likely would not happen again in the future.

His "large # of orphans" probably comes from a wrong chain...

how do you get back no the right chain???

ive got a 4 core at San Francisco, only two orphans on my digital oceans

my local machine has been much more lucky 8 blocks, have been mining for a while though (amd fx 6100) 6 core

I'm also running 5 instances of DigitalOcean VPS' (the cheapest ones), they seem to mine with 300-1000pps.

Each or in total?
Each Smiley

Now found 4 blocks in total with all my miners. This is too awesome

Well that's great, and which location?
Current stats:
1st droplet, San Francisco 1 @ ~960pps
2nd droplet, San Francisco 1 @ ~300pps
3rd droplet, New York 1 @ ~350pps
4th droplet, New York 1 @ ~430pps
5th droplet, New York 1 @ ~550pps

There seems to be a lot of variation, give or take a few hundred pps.
