At pool last block 2394, miner show 2417 Huh

Server is at capacity limit currently, frontend is slow, i'm working on it.

I thought Moneta used ring signatures...  Zcoin is different, yes?

No, Monero uses ring signatures. Moneta was just the name for Zcoin before it was changed to Zcoin (maybe because it sounded too much like Monero).

Too noisy scam accusations... Looks like some haters want to spread FUD badly.

We cannot be sure this is not scam, but we can be pretty sure there are people who badly want us to believe this is scam.
And those people are really active. I would tell they are too active. That's very suspicious Smiley

maybe its scam, maybe its some big thing. Maybe both. Time will show, anyway. Meanwhile... mining this  Grin

Frankly, code is law. If there's no premine, then the only I thing I can say is that it is not a scam.

Crazy. price went to 0.0035.
Today Fud start and price dumped hard to 0.0020.

Someoen's want cheap zcoin?  Grin Grin

I feel that when the new coins with new algo was born we can see many fuds from haters who joined previous projects or they want to buy many coins with cheap price. in my view I will mine some coins for my cold storage and buy some more coins when it is cheap. maybe it could be a second ETH in near future time

^^ Seems like it.

Regarding the "trusted setup" issue: ZCoin uses the RSA 2048 challenge number for its crypto setup. That's a publicly known semiprime number:

Code:
25195908475657893494027183240048398571429282126204032027777137836043662020707595556264018525880784406918290641249515082189298559149176184502808489120072844992687392807287776735971418347270261896375014971824691165077613379859095700097330459748808428401797429100642458691817195118746121515172654632282216869987549182422433637259085141865462043576798423387184774447920739934236584823824281198163815010674810451660377306056201619676256133844143603833904414952634432190114657544454178424020924616515723350778707749817125772467962926386356373289912154831438167899885040445364023527381951378636564391212010397122822120720357

And no one knows the factors, not even the RSA guys. Or even if they do, it's them who have the upper hand, not the ZCoin devs. Wink But seriously they don't, because:

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?

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...

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:

2 huber 84 7,057.705

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?
