One of the things I'm aiming for is an algo that is more friendly to mobile devices. NF14 is still pretty slow on ARM CPUs just validating blocks on the download. If it were completely up to me I'd go with an even lower, maybe NF12. Having a unique algorithm is protection in itself- I'm doubtful that there's enough reward for someone to go through the cost and effort to develop and produce an ASICs device for just us at this point in time.

Any change is going to disadvantage someone. Why shouldn't those with the higher end cards get a little bit of an advantage? After all they did pay for it. But NF15 or any other Nfactor isn't off the table. Let's hash it out. Do you have any more reasons to choose NF15 other than not to disadvantage those with low-end GPUs? Convince me.

The newer CPUs and GPUs coming out are shifting to higher cache/vram. When new technology comes out, it will definitely help your coin to be the most profitable for those who are willing to spend more capital on new products. Otherwise, people who have had their GPUs for years will just simply mine and dump your coin, and they won't even have to worry about ROI at this point...

Convinced yet?

That's unfortunate that Nfactor14 was chosen as that shifts the mining back in favour of higher end GPUs rather than the unique niche of Nfactor15 that made low end GPUs on par with high end GPUs. N15 is also a sweet spot as 2GB cards (high or low end) are still effective unlike N16+ that really starts to favour 4GB cards.

Nice to see the reduced reward to 10 from 30 though.

+1 on the NF change (heck, I love NF16 though!)

The test pool is up. Nfactor14 folks!

Feel free to abuse it- in fact, I encourage it. If the oscillations continue with the longer smoothing times, we'll tweak it some more. Hopefully 240 blocks will average out the highs and lows better and also lesson the chance of orphans at the lower difficulty swings.

This is what we'll be rolling with moving forward. The sources on Github are updated, please see the may2015 branch from http://github.com/Kracko/ultracoin-2 as that is what is currently running behind the test pool.

Here is the link to the pool: http://test.tumblingblock.com

Kracko, what are the correct settings for R9 280x? Starttime correct at 1388361600? Trying to mine but yacminer shows NF 16 and getting pretty lame results. Less than 1 Kh/s per one 280x.

You'll have to set your nfactor max at 14 (I think it's --nfmax 14) as it strays from the normal calculation from start time.

Set it where? In ATI Settings Calculator calculator? It gives me:
yacminer --scrypt-chacha --worksize 128 -g 1 --lookup-gap 8 --buffer-size 2590 -R 5120 -o stratum+tcp://: -u -p --nfmin 4 --nfmax 30 --starttime 1388361600
With that I'm only getting HW errors and less than 1Kh/s per card.

Edit1: ok, will try to set nfmax 14.
Edit2: it seems to be working. Tnx.

cudaminers use --algo=scrypt-jane:14 instead of --algo=scrypt-jane:UTC for the same reason.

I missed a few posts, but are there any news about the NF rolback?
When will it happen?

It's in progress, along with multiple other changes. For one, we're smoothing out the retarget from 10 blocks to 240. Hopefully that takes care of the oscillation and high orphans at the low difficulties with the increased averaging time. Once I have a working prototype ready I'll throw it up on a test pool and let you all have at it.

We need a proper miner. Whatever is out there is buggy, memory leaking and out-dated.

Can you back up your statement? I've got a miner that works great.

what miner and what GPUs ?

for the life of me can't mine this coin on any of my 6900's 7900's or r9 290's

just driver crashes or zero accepted shares , sigh Sad

Hey guys,

I need a hand here. I have 6 x R9-280X cards and I have had tons of problems getting any miner to launch normally. I've had no issues with my previous minings (SLG, Doge, LTC, MNC, USDE) but now I just can't get this to work.

Can someone tell me what to download and install ? Just one miner ? Do I need something else besides that ? Which miner is the best for me ? What to put to .bat file this time ? I've created account to official pool, tried their beginners guide but that never worked for me.

Chacha is very ram hungry, I dont think you will be able to run 6 cards efficiently on one machine, unless you have 16gb of ram
Mine miner required 8gb of ram for 3 cards to function properly.

Other than that get thirtys yacminer

Think people are missdirecting hate towards amd miners, cause of the poor AMD chacha mining.
On nvidia its much simplier and responsive.

Tumbling reported very high diff for several blocks (like 30+). I assume it was flawed data?
Will clear that from db.

Probably happened during the wallet switching. The external (block explorer and seed) and pool wallets (save the one currently being rebuilt) are in synch and up to date. The numbers have improved considerably already and should continue to get better after the rebuild operation.

I'm blaming latency as the primary reason for orphans on utc.tumblingblock.com. I've taken steps to reduce it and am in the process of rebuilding wallets. This will take some time and the latency will continue for a time. Utc1 is getting a bit long in the tooth as the wallet is already well past the size that caused Thiago's pool to freeze up. It's probably getting close to the time to wipe the database and start with a new wallet. I recommend setting up ultrablockparty.com as a backup pool, or even your primary. It really doesn't matter to me as long as you continue mining and help us on the Proof of Work side of the house.

you can try cudaminer with nvidia cards. Although its out-dated but it provides great performance & profit. I dont have dump everything to recover my costs, i sell only around 30%.
