my cpu is at 200% with the gui client and setgenerate true 2 but gethashespersec = 0. wtf?
I think now only the enterprise CPUs are able to mine the Zcoin. With every single block the hashrate drops...

Not yet. You can easily mine with i3/i5/i7 or even with older Core2Quad or Core2Duo CPUs for now. Hashrate will not be big, but decent enough, so you can get few coins per day with few machines. Depending on what they will cost, it could be reasonable.

I wonder where these guys are getting their CPU power from? This is on Suprnova:

Code:
Rank 	Donor 	User Name 	KH/s 	XZC/Day
1 paulscreen 112 9,458.737
2 huber 84 7,057.705
3 iflyplane 55 4,659.601
4 anonymous 34 2,874.489
5 anonymous 32 2,659.563
6 anonymous 26 2,192.228

112 Khash/s? Botnets or GPU miner?
The Supernova numbers are way off. I think the calculations are based on a different coin. ZCoin's entire network hashrate is 88.5 kH/s at the moment.

It's not KH/s but H/s

OC, with all the respect those numbers cannot be hash/s. Just one of my machines shows 17.95 hash/s locally, but all the machines combined show just about 1.2 something/s at Suprnova (in average). That could be KH/s or something else, but it cannot be hash/sec.

Now we have miner with 204 something/sec!!! That should be about 1000 CPU cores working, when estimated compared with my hashrate and shown number! Smiley

Yes, you're right, it's indeed kh/s, i'm a bit confused sorry.

Units are HH (hectohash, 100H) according to my stats,  but the pool reported speed still doesn't match the speed reported by the miner.
Very confusing.

Hey, Zcoin evangelizers!
What you think about CredaCash?

Not on coinmarketcap or any exchange so... I don't think much of it.

If this gain news about trust, then Creda will be only of the best coins to invest in 2016/2017. But really, are very good things to be true.

Matrix size is block height * 24576 bytes per thread. Currently that's 60 MB per thread or 560 MB for an i7 with 8 threads.
At block 1 million its 24.576 GB, at 10 million 240GB. With big Xeons it would be close to 1 TB at 1 million blocks.

I actually like the concept of increasing mining resource requirenents as block height increases because it protects against tech advancements,
faster CPU clocks, more threads, more mem, faster mem, etc.

The problem with the current algo is the curve is too steep. Memory requirements of the algo would probably increase faster than memory tech.
So what we have is an algo that is impeded from graduating to GPU* and ASIC while it's ability to mine on low end systems diminishes over time.
It's squeezed at both ends.

* I'm not familiar with GPU mining specifics but typically they have many more threads than CPUs so I assume greater memory usage.
Someone who knows please correct me.


So its turns out the RAM requirements could be more restricting, than CPU requirements. But from the other hand, with 10 min block target, block 1 million will be after 19 years!! I suppose the RAM size of 24GB+ or even 1TB will not be any problem by then...

Here are some benchmarks from the Height problem.


One of my CPUs on Block 2300 now hashes at 8.3H/s, while at Block 23000 it will hash at 1.35H/s. This doesn't take into account the difficulty changes by then. Every CPU will linearly follow this pattern.



I have a question...

I understand it will be increasingly more complex to produce a single hash. Some people see a problem in that, and expect the chain to stop at some point.
However, if hashes are be produced less often, the blocks will be found less often, the difficulty will decrease, and block will be found again, just with less hashes contributed. Is this correct?

So in short, difficulty decrease will compensate for the increased complexity of producing a hash. Doesn't this mean there is no problem at all?
