Wow, look at the buy orders at coined up  Shocked
There is like 9 btc demand on price about .0036, highest is buy offer for 2.5 btc at 0.0038.. wow.. investors are buying!! Probably good idea before next diff up Smiley

We promote the vertcoin to little! Just so few people know about this great coin. They see the name in the list and think just a other crap coin.. We need to make them clear this is something different! Then we also will get more votes on cryptsy and it will be on a lot sooner!

I'm tweeting and retweeting at Twitter, use the hashtag #Vertcoin

perfect you cleared the point. but this is still a weakness.

so every N-change we must re-tweak the gpus. hope it won't have a big impact on mining operations, people will have to shut down miners to do this, and i don't see such a huge fluctuation as a good thing (chance of 51%, forks etc.)

so maybe people should set the new thread concurrency BEFORE the N-change.

don't get me wrong, i think this is the future, but we must address all the weakness before the coins become too big... Smiley


I dont think this is necessary..
I was mining also MicroCoin, which is Scrypt Jane, not exactly same as this algo, but simillar and even though n factor changed there and hashrate was like 3x lowered during time I was minting it, I never had to tweak it..
I think there wont be this need as well..

i'd like to address a possible issue.

looking from this table (results for hd6690 on yacoin)
http://explorer.yacointalk.com/graphs.htm#tech

in november 2015 when vertcoin switches to N=8192 there will be a *huge* drop in hash rate. cpus will continue to mine, while gpu will be useless suddenly.
that will cause confirmation times go to the moon, because hashrate will drop thousands of times suddenly.

ok maybe the new cards like r9 290 will be able to mine until N=16384, but this will only postpone the problem.

start thinking about the kimoto gravity well, it will be necessary even without multipools jumping in....

I think N should be also related to or proportional to the difficulty or something else, but do not adjust it artificially such as by hands or according to the timestamps. Too large N kills every hardware.

6990 and r9 290 have the same size of memory, they will be killed at the same large N=8192.


Well, no the 6990 is 2x2Gb cards in one.r9 290 has double memory per gpu chip.
Vertcoin, sure they increase a bit the memory but not exponentially. And we want everybody to mine, not just those who can afford the new high-end cards, otherwise it's useless, and its the same as having asics...
Maybe a silly question, but when VTC hits N-Factor 8192, why is that a problem for GPUs? The chart indicates a memory requirement of 1MB, compared to 512KB at N=4096. If that's per hashing thread, then at N=4096 a card with 3GB (7950, 7970, etc.) could still run TC=6144 while at N=8192 you would have to drop to TC=3072. You certainly won't get the same performance at lower TC values, but tweaking will almost certainly mean it's not going to be half as fast. Newer versions of cgminer and such will likely also play a role. In other words, there's no magical N-Factor at which GPUs are suddenly unable to perform the hashing calculations. In ten years when we're at N=131072 and using 16MB, a 3GB GPU could still run with TC=192. Then again, ten years ago we were looking at GPUs with a whopping maximum 256MB VRAM, so in ten more years we might be running GPUs with 144GB RAM. :-D

you are right.. nice one

Vertcoin has a good promise that is to render asic miner useless.
I hope the devs keep on that promise and make it a GPU mineable coin forever.
No to ASIC miner and No to CPU-miner.
Long live GPU mining.



lol,
this coin was firstly designed as CPU only Cheesy
but I think nobody really minds that it is now GPU mineable..
GPUs are just peoples way as ASICs are in hads of rich early btc adopters and pure cpu coins are controlled by hackers using their botnets on mining.. so GPUs wins Smiley and lets hope it stays this way for long time!

Vertcoin,
An idea to keep hashrate stable during an N-change could be to change the difficulty according to the next N. when N is doubling, difficulty gets halved.
otherwise we need a full retarget every N change (7 days because the hashrate halves with N doubling)

I can be wrong, but it's possible to change diff retarget time. Ain't litecoin did it?

anything way to get more  kh out my cudaminer 550ti

I have GTX 550 Ti and i'm getting around 37kh. So I guess you won't be able to get out much more.

I think this coin will be the next litecoin once scrypt asics hit the market.  Glad to see this one had a fair launch.

Probably even much earlier..
There is big mess in scrypt coins these days.. new launches are comming daily and it seems to me uninnovative alts are kinda loosing its value with every new coin, this is not the case of vert.. value rising hardly even though bitcoin falling, litecoin falling, doge coin falling Cheesy
Viva la Vert!

Is there a trick to CPU mining?  I am using the modified CPUMiner and getting accepted shares in the miner but they are not showing up as accepted or rejected in the pool, I have tried LA.VERTCOIN.ORG and NY.VERTCO.IN.  I am familiar with ALT Coin mining and yes I do have the correct username and password set in my .bat

is it worth mining when only getting 32 kh,cudaminer 550ti

should get you around 5VTC per day, I think. or 0.00175btc at current rates.

but I think is good investment Wink

Well, if anything is worth mining with your card, it is Vertcoin - depends what "worth" mining means, but if you forsee the kind of future I do for VTC, then certainly, I would say mining it is "worth" it.
