If you were to implement a CPU-only coin...

[ZirconiumX]

...How would you do it?

I, personally, would use something like AES as the base cypher, due to AES-NI. But then, AES is pretty easy to implement on a GPU.

I note Quark uses multiple cyphers, but again, those aren't hard to put on a GPU.

make something in it require windows to run if that is possible

if people want to fire up the vps clusters at least it will hopefully cost them a lot more to rape all the coins away.

Memory intensive would prevent GPUs as the transfer rate to/from GPU kills productivity.  On my old project, there were 3 different tests, trial factoring (at which the GPU was 100+x faster), LL tests (at which the GPU was 6-10x faxter) and P-1 (which works in 2 stages, I think they got stage 1 to work at 2x speed, but I don't think they ever got stage 2 to work)

huh? As a linux user i find that statement highly offensive.

I found it highly entertaining. 

In an ideal world, bot nets would be useless for mining coins.  Problem is, you'd have to have something like a captcha that could not be faked.  That way each person would be equal, none of this 'He who has the most cash/bot-net/farm/whatever wins'.

I'm just imagining it now "Congrats, you found a block!  Please enter the following captcha to claim it"   <Bzzzzzz> Sorry, you were too slow and were beaten out by a 12 year old!

Clearly, there's no Windows VPS clusters.

My thoughts exactly.

...How would you do it?

This might be interesting -
http://security.stackexchange.com/questions/15373/hashing-algorithms-on-gpu-32-bit-vs-64-bit

So, lots of 64 bit operations. As mentioned already, memory intensive. I've seen mentioned elsewhere that GPUs are not so good at conditional branching. So lots of that too.

[digitalindustry]

If you were to write a cpu only currency ....

I would pay someone to write a gpu miner for it .  Or anything else.

Because it would be rare enough to justify it .

[SirMintALot]

I would use a combination of bcrypt (uses lots of memory operations) and sha512 or keccak512 (64bit arithmetic).

[Palmdetroit]

The solution to resistant mining to current evils (VPS and botnets).. is to have a coin require insane amounts of RAM.. maybe 8-16 gigs just to start with... 32-128 to mine fast

this would put the above to bed.


hook me up if you use this in a coin

as an internet user I lol'd that you guys found dribble on the internet you found offensive

That deserves a generous *facepalm*.

The bot net would set up a site with naughty pics, for free but surfers must solve a captcha to see them,
then let the surfer solve your captcha. This was a new bot trick in 2007

Wouldn't work. I would just compile a version without the capatcha.

As a windows user I find the statement by going to Start->All Programs->Offensive statements, or by typing in it's name after hitting start.

This is probably the most retarded thing i have read all day.

This would be VPS Heaven.  How many people do you think have that kind of memory in a desktop or laptop?

[crendore]

The only way to block botnets from CPU mining a coin would be to implement some physical access lock into the software.  For example a USB thumb drive that contained a signature of some sort.
