From the "shoddily made flow chart", this algorithm looks like essentially a more complex and simpler (in different ways) version of scrypt, just with very high memory requirements. It is probably just as weak to ASICs, though I can't say for sure without more information. Do actual specifications exist for the algorithm? Also, is anyone interested in doing a BFGMiner port I can merge?
This algo mines via hdd capacity. Only way an asic would be useful is during the plotting process, but that's not a mining process. It doesn't have to be a HD, it could just as well be (a lot of) RAM. This is essentially the same way scrypt works, except scrypt altcoins aren't using as much capacity. It's possible to do RAMDisk, but that's not a very cost effective way of mining. You would need a bunch of TB worth of RAM to mining with as oppose to cheaply doing it with HDDs. You try it out and give the results if it is worth it. Yes, you can do the same thing with scrypt... I didn't say it wasn't possible or not, I was just pointing out that it would not be cost effective. This algo proof of work is done via capacity, the larger the plot, the more efficient the deadline results are. When it comes down to it, all aglo's use storage/memory of some sort of form, may it be System RAM, SSD, HDD, VRAM and/or temporary usage of cpu cache.

Yes, you can do the same thing with scrypt... The key part you may be missing in the "shoddily made flow chart" is that it "Does not include caching plot\[s\] to disk and retrieving them." For $130 plus plotting and optimization time, a 4TB drive can store about 4*(10**12)/(2**18) = 15,258,789 precalculated values corresponding to the boxes in the bottom right-hand corner of the diagram (i.e., "Hash, then hash with the resulting hash, etc.") The other hashes in the mining calculation are fast or only computed once per block, so you can check these 15M values as fast as you can read them off the disk. Even the latest bitcoin mining hardware provides at best 5 orders of magnitude speedup over CPU hashing speeds, so your custom ASIC burning hundreds of watts might just about come within an order of magnitude of the speed achieved with cheap commodity hardware burning less than 10 watts (see figures 11-13). A custom ASIC for shabal hashes would be super useful for the initial plotting, though.

It doesn't have to be a HD, it could just as well be (a lot of) RAM. This is essentially the same way scrypt works, except scrypt altcoins aren't using as much capacity. The flowchart is missing the caching and retrieving from disk parts. Since the account id and nonces are run through the repeat hashing step before any network state is used, the results of the repeat hashing can be saved and reused every block, with the miner only having to do the repeat hashing once ever per nonce. This makes it so the computational expense of that initial repeat hashing can be increased any amount without causing miners to do any extra work after the initial caching process. The more expensive that repeat hashing step becomes, the more efficient using pre-cached work is over computing everything on the fly.

11 Days without a block with 9TB - what is going on with this thing? Was finding a block every day or two at most for the last 50 days until the 8th of October. Everything running as it should.
There's a spot of bad luck and then there's this.

I don't think Java miner is having any problem, I'm on pool but it works great (shouldn't be that different) Maybe a big bad luck timeframe?

I think it's just the fact that you're competing with large pools. It even takes out small-med sized pool a while to find a block... I know that Uray's pools find a lot and so does the dev's v2.

Question: are you just looking at your miner's output, or are you watching what the pool is reporting, too? Because, since 1 week ago (sort of), I have been looking at both at the same time, and this is what I found: - Client (using dcct's, but happens with java client too) reports a deadline of 6/7 digits. - Pools (tried several) report a deadline of hours. I don't know if it's the client's fault, or the pool's fault. But we are paid by the pools, not the clients, so what I see the pool report is what is used to calculate payment. Anyway, there's some serious fail coding somewhere. I've seen so many people talk about the future of this altcoin and focusing on advertising and investors, blah blah, but the blunt truth is that any investor will not want to invest on something that is so broken.

Some of third party tools are incompatible or have known issues, but dev can't be held responsible for other developers code. Did you try dev2 pool? I've checked the shares list and it did register all the shares which were sent to it.
