Please correct me if i'm wrong, but isn't Quark only as strong as the weakest of its hashing functions ?

you are wrong -

and SHA256 is only one hash function - ?

No, the hashing functions are applied one after the other.

The result of the first hash becomes the input of the second hash, the result of the second hash becomes the input of the third hash and so forth.

So it's more like the layers of onion skin, and NOT like a chain (with a weakest link)

so, in pseudo code:

Quote
hash9(hash8(hash7(hash6(hash5(hash4(hash3(hash2(hash1(...)))))))))

(now correct me if I am wrong)

so we have the EQ reward coming up right

When will this come up, and is this already inspectable at github?

not claiming "the best" mathematics  just claiming as secure as Bitcoin - that's all  -

people have personal differences about the SHA256 being designed by the NSA and registered with NIST - , but personally i don't find this a huge issue -

its a non issue for me -  

i have always had a problem with the centralization - and distribution model =

I agree. Evolution is about surviving, and not about being the best.

So while I think that qrk is interesting at the moment, I hope it will not end up as the Hors d'oeuvre of the upcoming t-rex coin.

And about the NSA thing, to be honest I don't care.

The whole early internet was largely based on US military research... and look what humanity has done with it. Government has created it's own biggest enemy. That's how it goes.

So as long as something is open source and available for everybody to inspect I really don't care if some bad guys participated in it at early times (for whatever reason)


Government bureaucrats never understand the future implications of some research they are doing... ofcourse not, they are not free market enterprises who have to understand something to make a profit.
I see them as very well funded but inneficient goons, who are allowed to do all that because we have this taxation system based on force and coercion.

But that doesn't mean that government mathematics can't be useful for us at a later moment. Science is science.
Math is neither good nor evil,  it's just a tool.

OK thanks for your answer georgem. So if one of the hashing functions was compromised, then the others would do the job anyway...

Now that's interesting. That would make Quark the most secure of all the alt-cryptos out there ?

I agree, it's getting very hard to find untrolled discussions.

Now about these 6 algorithms : blake, bmw, groestl, jh, keccak, skein... I wonder which one is the most secure ? Some of them must have their drawbacks ?

Well, that's what I want to find out too, that's why I asked for some sourcecode.

EQ supposedly is some kind of "fix" that will help create more incentives for miners to mine QRK (and therefore secure transactions) after we leave the 6month initial mining period, and enter the 0.5% per year mining period.

http://forum.qrk.cc/thread/874/quark-secured-after-initial-distribution

If that is something new that will be added soon... I ask myself what is this that we have now??

How is the issuing of 1 million coins per year controlled at the moment, and how will it change once the EQ-Fix will be applied?

Will the EQ-Fix simply add more money per year for the miners? Is that what I am reading between the lines?

The miners have only one incentive: making money, and securing the money they already have.

or maybe I misunderstood this.

Is EQ-Reward simply the name of the 1-million-coins-a-year period ?

Or is this something new that will be added?

For those who don't know yet.
There is a Quark Introducton Video in progress.
People are donating to this project.
If you want to donate or have suggestions for a storyboard for the video, make a post.
It's going to be good.

Also CoinKite seem to be interested in Quark.
http://www.reddit.com/r/QuarkCoin/comments/1tev2y/quarkcoin_on_coinkite/

Help make some noises and get Quark onto Coinkite.
Here is their facebook and twitter.

How many hashes does it take to find a share?
Current Network Hashrate 769.5147 GH/s
Block Interval 30 sec
GigaHashes per Block 23,085.441
16 Quarks per Block (Halving to 8 SOON)
1,442.8400625 Gigahashes per Quark

Is that what you had in mind?

want to make a calculator for MH/s
i have formula and i need hash per share:
Code:
var SecondsPerYear = 365.25 * 24.0 * 3600.0;

var hashTime = difficulty * hashPerShare / (1 * 1000000.0);
var blocksPerYear = SecondsPerYear / hashTime;
var coinsPerYear = coinPerBlock * blocksPerYear * (1-1/100);
var coinsPerDay = Math.round(coinsPerYear / 365.25 * 100000000) / 100000000;

769.5147 GH/s is really a huge number, considering that the hash rate of a single computer is 0.1-1MHash/s. This essentially means there are at least 769,000 computers are connected to the Quark network...
