[ANN][XCN] Cryptonite | 1st mini-blockchain coin | M7 PoW | No Premine

[dunchy]

This shit is going down the drain as soon as someone forks it and make a fair release with gpu miner at very launch. This is DRK all over again..Price after only  4 days passed is just ridiculous. Anyone still dumb enough to buy will just be a bagholder.

Just fork it and use a different PoW.

If you want people to be able to mine at all on CPUs while also having GPU miners, use Cryptonight (from Monero), otherwise just use whateever X-blah variant is popular now or even Scrypt or SHA. If the mini-blockchain is the thing that makes this valuable then there is no legitimate reason to concoct a brand new PoW.

I'd also suggest the slow-start reward thing I mentioned several pages back. Ramp up the rewards over the first week or two so whatever initial launch issues there might be (bad builds, not enough seeds, etc.) get fixed before the full reward kick in.

That's the way to do it! Looking forward for Cryptonite's monero !

well, I decided to give this coin a shot, found out there's no pools, boo, so i set up a wallet to solo mine on 4 different i7 computers, been almost 24 hours now and one of them did find one block, so i guess that's good? hurray? can't really see how fast it's mining in the wallet, used to seeing my hashrate and accepts flying by on the GPUs i mine with. all i can say is that in task manager the wallet's cpu performance is at %90+ so it seems to be working.

my concern is the price, it seems incredibly inflated. there's over 300,000 new coins meing mined a day, so in 10 days this will have as much coins as cloakcoin for example (of which the price seems appropriately compared to) but after that it's just going to get diluded. in 20 days it will be worth half as much. to me this seems unsustainable.

i've never heard of a coin with 1.84 billion coins that's been worth 8000 satoshis. that on it's own is just very impressive, but I gotta say, as an investor, i'd be looking to short this right now, no way this is a sustainable price unless you want to valuate this being worth as much as 100x doge right out of the gate. 10x maybe i'd believe, but not 100. this is silly.

I'm rather a fan of the PoW, seeing as how i wrote it and all. I think nobody has really sat down to think about how hard that "silly multiplication" is for GPU's and ASIC, and there is no evidence that a GPU miner has been created. I'm working on one in spare time to prove how much it will suck. I mean it will work, but won't be massively faster than CPU. Especially if someone sits down to optimize CPU for AVX. The ultimate combination is probably GPU for hashing and CPU for multiply. Might get somewhere doing that but it's a whole new kind of rig to have that kind of balance.

Lemme give you some numbers:

750ti = 160 32x32 bit multipliers @ 1gz = 160B 32bit per second
4770k = 16 64x64 bit multiplication per clock @ 3.6ghz = 57.6B 64bit muls ~= 330.4B 32bit per second

Theres no fighting that. It is raw ALU power.

Have you actually profiled it? I have, and most of the time is currently being spent in the hash functions, not the multiply. Granted that is CPU not GPU, but I'm skeptical that multiply will be a major bottleneck. Someone may prove me wrong, we'll see.

AMD GCN, for instance, performs any VALU operation in 4 clocks. mul_hi and mul_lo are two disctinct operations though, so it takes 8 clock to multiply two 32-bit ints in all running threads. An addition or bitwise operations take 4. Multiplication is obviously not the bottleneck in this design.

Seeding works pretty well, actually. Here are a few running now, just in case: 216.51.224.242, 210.64.51.11, 58.220.3.208, 71.8.128.127

On CPU multiplication is highly optimized, for GPU even the oh so hard to do methods will have big time problems. I'm willing to believe that most of time is spent in hashes on CPU, but that can change if somebody optimizes the difficult hash functions, and is only true because the CPU is so efficient at multiplication.  Like I said I think doing the hashes on GPU and multiplying it on CPU will turn out to be the setup. How much that buys you I don't know. Maybe you triple performance of a 4770k by adding a 750ti? Whatever it is won't be any sempron with 1x pcie. Maybe a 750ti goes same speed as 4770k by itself. These are all possibilities that don't seem highly advantageous to me.  Still going to get mopped up by a dual xeon on EC2 without the capital costs.

Pretty sure nobody has it, although Wolf has been quiet for the past day. I'm working on it.

AMD GCN, for instance, performs any VALU operation in 4 clocks. mul_hi and mul_lo are two disctinct operations though, so it takes 8 clock to multiply two 32-bit ints in all running threads. An addition or bitwise operations take 4. Multiplication is obviously not the bottleneck in this design.

This is true but it depends on what you think of as threads. thing is a barrel processor and a "clock" really takes as many cycles as it takes to get through the barrel. Really you have to figure instruction issuance rates which is the SIMD width * number of cores * clock rate. The number of resident threads in the barrel does not increase issuance, only the probability and instruction is able to issue on every clock.

Also GCN has only 24bit multiplier and there are some extra instruction for combining even 32bit multiplies into 64. You need 4 mul + some adds. And then you have mul_hi mul_lo. So it's a whole mess of instructions. Not to mention amount of memory required. Probably to big for lmem so you have lots of load/store traffic going on.

The hash implementations looked reasonably decent to me. Perhaps that is not the case, I haven't looked carefully, but it is at least trying to be fast. See Tuning at http://www.saphir2.com/sphlib/

There might be some advantage on the 512 hashes to dump the upper bits of output since I think they are not used. I'm not sure how far back into the hash algorithm this is effective, but my guess is not that far.

[mmmaybe]

I'm still getting many rejects on http://xcn.1gh.com, accept rate is pending between 72-85% on 5 different boxes.

Any ideas, reorder? Anything miners can do?

Reorder is working on something with midstate on 1GH. Can be improved further I believe. Can also prepad the hashes. Bunch of things can be done. sph is not bad just doing things that don't need to be done repeatedly.

All bits of the hashes are used. The product is some nearly 3000 bit number which is hashed into sha256

Okay I agree midstate will have some benefit here. I don't know how much. It is a long way to go before the multiply becomes a bottleneck.

Thank you for the correction on the multiply output being fully used. That does help.

I agree, this coin isn't a speculator's coin. Not sure why he chose this structure.

If you run several workers, please try using different wallet addresses to get a lower share difficulty for each. Cryptonite has important block bits updated with every transaction appearing on the network so we have to update miners tasks frequently too.

New Mining Pool  1% Fees!

http://pool.minichain.info pays out once a day proportional to the number of shares (share difficulty = 512)
Also check out the blockexplorer at http://minichain.info It might be down sporadically over the next few days if I'm working on it more

If I get enough interest, I'll release the source code for both
