can you explain the hash function a little bit? and 1 day diff retarget is going to pillage this coin until it reaches block 1440.  
*edit, the retarget is max 400% higher so it may take a few 1440 rounds to stabilize at 1min block time target.  currently 20 minutes produced 800 blocks Cheesy

$MAID & $BTC other than that some short hodls and some long held garbage.

Sure, this is intentional. In our opinion coin launches shall favour early adopters allowing them to mine a lot.

Some of the best coins start this way. No premine is also a great thing! no standalone miner so no botnets yet. Kewl!

Yeah hold on to that standalone miner for at least a week Smiley or don't do one Smiley

Cool, I like, and I'm intrigued that the gpu miner experts put together a non gpu minable coin or rather one that does not favor gpu mining.  +1000

So no one can make a pool until you put out the cpu or gpu miner?

Algorithm details:
Roulettecoin uses custom designed randomized algorithm:
  • first block is hashed with sha2
  • then 16 rounds of hashing are performed, each round with randomly chosen algorithm from the set of 16 hashing algorithms: blake bmw cubehash echo fugue groestl hamsi jh keccak luffa sha2 shabal shavite simd skein whirlpool
  • for each nonce value combination of algorithms is different, there are 16^16 = 18446744073709551616 possible combinations overall. Therefore it's not possible to use SIMD advantage of GPUs, because each GPU core would have to compute different instruction flow.
  • It's possible to optimize GPU miner by computing all algorithms for each round (then GPU can use its SIMD advantage), but resulting miner is still slower than CPU miner.


Did you people read this? How is this innovation not getting any more attention?Cheesy

Or are people just mining it in stealth so they can gain most of the coins for themselves?

Mining with the wallet on the same rig mining another scrypt coin lowers my cgminer hashrate by almost 50%. This doesn't happen with any other coin I mine using a standalone CPU miner.

Thats what I'm doing. I have one wallet on each of my rigs and one on this computer.  Grin To fix the 50% problem just mine with 1 less CPU thread.

How do you change threadcount on the wallet debug window?

setgenerate true 4 or whatever amount of cores you have.

We felt sorry for CPU miners after creating so versatile GPU miner for CPU-only coins, so now we created a (hopefully) true CPU-only coin.

oh please.

Cute idea and it's going to make the GPU fun, but this is a bogus claim.

Process roughly 4096 keys at a time in 16 different workgroups, each working on a specific algorithm, shuffling the keys between them as they switch between rounds.  Requires a little more attention paid to global memory use because the keys are probably too big to fit in local, but there's nothing fundamentally hard about this coin.
