How many hashes does it take to find a share?

At difficult 1 we need 2^24 hashes approximatly for a block (16777216 Hashes)
So at a diff of around 5160 we need 2^24 * 5160 hashes = 86570434560 =~ 86,5 GHashes

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 ?

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 ?

Really, whatever hashing function you use: As long as there are no reasonable collision attacks and such stuff, its irrelevant of the hashing algorithm used.
Yes of course, have a newer ("more secure") hashing function means, that the point in time when the computer technology is so advanced that this is doable in somehwat reasonable time, that this point in time is later, but really who cares?
Just do a hard fork and replace the hashing algorithms for all blocks newer than block X.

And currently Quark also uses SHA256 for the Merkle Tree...

What are "Transaction Fees" and why are they important to Bitcoin and Litcoin ; Why and how does Quark have no Transaction fees ?

[...]

in contrast:

Quark provides its users and investors with a Fee FREE environment this is because of the EQ reward , this means that if you are a SME or small business ,or a home business ; www.keepitwooden.com/ < (i'm buying some : D) you have no fees to worry about what so ever -

Once again: schmarrn

Please read the code before you are stating such things which are provable wrong.
That is what makes others think about quark as scamcoin

Quarkcoin HAS transaction fees, and follows the same rules about "free transactions" as Bitcoin.
And since these rules were made for bitcoin, but in quark we have a faster block time and most of the time a bigger volume (important for the priority calculations) often the requirements for free transactions where met.
Remember the problems with transactions (mostly from p2pools inputs) hanging in the network. This happend because of that rules.
