[ANN][YAC] YACoin ongoing development

[hanzac]

Add this to the list of tasks to simplify in yacoin. Looks like it needs yacoind.exe under windows.

I don't think yacoind is needed, yacoin-qt can also run in server mode. You can check debug.log, and you'll find some log like POS CPUMiner started

How do I get network hash rate with yacoin-qt? That's the main reason I want it.

Everyone is welcomed to mine on my p2p YAC pool

http://31.220.1.53:8335

In order to mine

Code:

minerd.exe -a scrypt-jane -o  http://31.220.1.53:8335 -u Y1dncJeBobRiYiBop6LWsUXq9fm8HbQfsp  

Replace Y1dncJeBobRiYiBop6LWsUXq9fm8HbQfsp with your yac wallet address and mine away.

Pool pays out each time block is found.

No registration needed.

I'm not that knowledgable on bitcoin. however I read this on a different thread:

"51% is real, back in 2011 it was more common on the alts. DoubleC was hit a couple a times on his exchange. Geistgeld 1 and Fairbrix were both 51% hit, so was the original Solidcoin and I belive I0coin several times"

I'm not sure if these 51% attacks were deadly or not. but Is there a worry about a 51% attack on yacoin?

this data from yacoind about 2000 blocks ago, or 30 hours ago:

 "blocks" : 72225, "networkhashps" : 103314719,
 "blocks" : 72419, "networkhashps" : 267124100,
 "blocks" : 72598,  "networkhashps" : 126571030,

Assuming not some error.

someone added 160k kh/s to the network to make up over 60% of the total hashes per second.
shows that someone has a OpenCl implementation of scrypt-jane and a GPU farm at their disposal.

Based on calculations in my head with the current YAC price at 0.0003 it seems more profitable than bitcoin (at least until difficulty adjusted - but maybe still then). why take it offline?

Maybe there could be the Amazon EC2 argument. this is possible but the person had to have an unrestricted account. because if you put up 20 (the limit) of the 88 ECU instances in all three locations. you get 60 instances of 250 kh/sec at n=256, which is only 15k kh/s.

the next closest instance rated at 26 ECU's would give around 60 kh/s. this type of instance I believe is unrestricted. but you would need 3,000 of these to reach 160k kh/s

We are hitting n=512 in a couple hours, by the way.

Interesting, where do you see this 160Mhash ?

He refers to the second row of his sample.

How could anyone have an OpenCL implementation of scypt-jane?

I didn't think that was possible, not even theoretically.

you should go ahead and read a few pages back in this thread. This has been covered multiple times already.

The code I added to yacoind to produce the "networkhashps" info is only an estimate, and is based on spacing between solved blocks over a fairly short period of time.  There isn't a way to directly measure hash rate, the best we can do is estimate it.  Variability is capable of producing the swing you observed above.  From my own data collection process that keeps track of average block spacing, at this time my opinion is that there wasn't a sustained rise in (estimated) hash rate that would be outside the realm of variability.

Now, if the estimated hash rate jumped and then stayed at that level, that would be more interesting and much less likely to be just a variability-induced fluctuation in the way my hash rate estimation code works.

I copied a good portion of the hash rate estimation code from Litecoin.  Our (target) block rate is 2.5x faster than Litecoin.  Perhaps I should tweak the code to average the hash rate estimate across 2.5x more blocks than Litecoin does to try to smooth out some of these swings so we're at least averaging over the same amount of time.  Even Litecoin's hash rate estimate has some pretty wild swings due to variability.

Hashrate for me looks to be around 125MH

$ ./yacoind getnetworkhashps
125940739
(then about a minute later)
$ ./yacoind getnetworkhashps
128083276
(another minute later)
$ ./yacoind getnetworkhashps
127557858

Guys, have you seen bitminter.com? Very neat pool. They do something similar to what we were talking about with bitcoin. Java web start client...relative no-brainer to get started (certainly a LOT better than setting up cgminer). I use cgminer/anubis with my farm, but ran their client on my workstation to try it out. It looks like they have about 8000 miners on their systems, around 2/3 of which are using the bitminter client. Funny thing is, their client does detect the CPU and offer it as a mining device, although I don't think that's used much anymore.



Another option is to create a pushpool client that works like this. A mmcfe fork could be created that offers services like statistics, registration via an API, to allow the user to just download the client and register from it, as well as viewing their statistics. There could be a master pool directory web service that could be used to allow switching between pools possibly. If something like OpenID or Google Accounts OAuth was used, registration could just be off of their google account, for instance, further simplifying things (this is how bitminter works for the initial signin).

p2pool is probably the most "resilent" way to do it, but my thought is that p2pool has a major deficiency currently with their statistics feedback. In short, it really sucks (IMHO). Any user of a tool like this wants to see, at an absolute minimum:
* their current hashrate
* estimated coins per day
* graph of coin yield over the past week or so
* graph of hash rate over the past week or so

This info doesn't necessarily need to be in the tool itself, but has to be available. With bitminter, it's on their site when you're logged in.

If anything, this is food for thought to me at least.

We are hitting n=512 in a couple hours, by the way.

When is that going to be?

How are you getting these relatively high hash rates?

On my W530 laptop (which is no slouch, it has a core i7 w/32 gb) I'm way down around 10 kh/s, which I don't understand.

What are you guys mining with?

Are you using this ? If not do it ! Use the AVX version.
