[YAC]: YaCoin Information Thread

[rbdrbd]

I wanted to put together this info thread on YaCoin to help others learn about it and centralize all info on it in one place. Please feel free to reply to it and suggest anything that could be added or modified. I've modeled this page after the LiteCoin information thread here.

If this list if helpful to you, please consider sending a donation to Y2e1VP9ZpwYCbVMk7RRhGDLwRKyuQwjzGQ. Thanks!

The [YAC] YaCoin Information Thread



What Makes YaCoin different than other AltCoins?

* Currently the only CPUMined coin (with all other altcoins, CPUMining has become unprofitable as GPUs, FPGAs and/or ASICs can do it much more efficiently.
  * Means that anyone can get involved with mining YAcoins. You don't need a fancy AMD video card, and a complex miner program with a lot of technical know-how
  * This may also mean that the YaCoin coin distribution is and/or will be more widespread, and thus more democratic (this is speculation at this point)
  * Also means that YaCoin could see a larger, more sustainable network hashrate, as miners can co-mine it along with GPU-based coins
* PoS and PoW (long-term power efficiency)
* Ultra-fast confirmations
* A reasonably good developer (pacopaco) and an enthusiastic community

The creator of yacoin (pocopoco) states the following about any potential move of GPUs over to mine YaCoin:
"it is possible to develop OpenCl or cuda miner for scrypt(N, 1, 1). But the CPU / GPU hashrate difference will be less than 10 times and will decrease over time. So GPU's contribution into miner's total hashrate (even in case somebody will implement this) will be like one or two additional CPU cores. This is because scrypt will need more and more fast random access memory with N increased." (Source)

Does anyone know how to enable PoS mining with YaCoin?

[kalgecin]

yeah.... i was also wondering.....

[Adamlm]

very nice summary of YAC related info, I will be watching
PS. The logo is awesome

[Boba]

I thought yacoin.com is being worked on by pocopoco, perhaps he wanted it to be finished before launch, and thats why the launch got delayed. But this is just speculation on my part.

[barrywu2013]

[xibeijan]

As more an more people actually try out YaCoin, it will become clear how fast (and robust) transacting in YAC really is.  At this point, early on, it must be a little unclear.

As more and more folks give mining a go (as N increases), it will start to become clear whether even CPUs can mine blocks throughout time.

Hopefully YaCoin will attract more developers and also sites will start to accept YaCoin.  I think there was already a gambling site that is accepting it.  Saw a forum topic.

Sucks that pacopaco is only reasonably good.

We just don't know yet.  We have to see if he keeps the YaCoin software stable and continues to develop and fix bugs.

His idea is genius, so I've got faith in him.

We should probably change the text on those pages from saying "reasonable" to something like "totally amazin'"

[xibeijan]

Sucks that pacopaco is only reasonably good.

Well to be fair, he did commit some huge changesets all within something like 36 hours.  There have not been that many bugs.  The idea seems solid.

Perhaps it's unfair to say "reasonably".  Perhaps we should say "awesome".

Let the plebs decide.

The proposed proof-of-work algorithm doesn't sound at all like a good idea to me - I suspect it would prove to be even worse than Litecoin's scrypt.

Are there details on your proof-of-stake implementation?

Time will tell.  So far so good.

[xibeijan]

Some folks should organise together and see about getting some online shops to accept YaCoin for payment.

Perhaps a bounty is required?

[bitdwarf]

Are there details on your proof-of-stake implementation?

I don't think it's changed from NVC. In my view the problem some PoW + PoS coins had is that PoW would just not die, which defeats the energy saving purpose of PoS. If YAC's PoW stops working at some point that may be good and solve that problem.

[Luke-Jr]

I was under the impression PPCoin's PoS was not really working yet, and that nobody else had done any development on it...

Update after reading some code:

• Nfactor is only used for memory allocation size - so it has no actual effect on the implementation; in other words, N is not dynamic
• The code is quite messy, and even something as simple as the memory allocator is broken (it pretty much ignores the size of the allocation request)

I think this one gets a "scamcoin" classification...

I've written a throttling script for Linux to tune down yacoin-qt when core temperature is too high:

Thread: http://yacointalk.com/index.php/topic,34.0.html

Code:

Code:

#!/bin/bash
while true
do
	t=$(sensors|grep Core|awk '{print $3}'|cut -b2,3|awk '{if (NR==1) print $1}');
	brake=$(ps -e|grep cpulimit);
	if [[ $t > 65 && ! $brake ]]; then
		cpulimit -e yacoin-qt -l 99 -b > /dev/null 2>&1;
		echo "Temperature is $t. Throttling down...";
		sleep 15;
	elif [[ $t < 65 && $brake ]]; then
		killall cpulimit;
		echo "Temperature is $t. Throttling up...";
		sleep 5;
	else
		sleep 3;
	fi
done

You may need to install first cpulimit.

When you finish it with Ctrl+C it may leave cpulimit running, you'll have to kill it afterwards.

Modifications are welcome.

Luke-Jr, interesting comment. I had a brief go at the code as well, but can't confirm your findings. Maybe you were a bit quick shouting "scamcoin", eh?

• Yes, the scrypt codebase is ugly. #define's and #ifdefs everywhere. Is this a copy of the original scrypt?
• The scrypt romix code in scrypt-jane-romix-template.h (function called SCRYPT_ROMIX_FN) does use N (i.e. Nfactor) looping from 1 to N, in addition to increasing the mem size by N. I don't know enough about the underlying crypto, but I believe complexity scales at least by O(N²).
• The allocate and free methods are totally fine. You have tripped over an #ifdef:
  

Code:

#if defined(SCRYPT_TEST_SPEED)
// jomay: I left out the test code - this is the one you've read.
// It works fine in practice as well, but makes the scrypt() function non re-entrant.
#else
// jomay: here goes the real deal - fully functional, no mem leak, fine.

I don't see any problem with pools,

Pools are ways to recentralize a distributed network. Instead of a lot of independent nodes, you have a few of important nodes, easily attackable.

See what happens in BTC with BTCGuild and later with DeepBit.

especially if it's p2pool.

A significative advance of YAC would have been a reward system that internally acts as p2pool does. If p2pool is only an option among others (these eventually more attractive because of less variance), it is no advance towards avoiding recentralization.

[Luke-Jr]

And how would you fix that? There is no way to prevent 3rd parties from pointing hashpower to one node and use that node as miner connected to network.

Something similar to p2pool (but not exactly) could be integrated to Bitcoin in such a way that it makes centralized pooling infeasable.

I follow this subforum, with the hope a new cryptocurrency comes with a solution to this matter, which would be IMHO a major break in crytocurrency development. But no chance...

In fact, I have my own ideas on how design a new CC with PoW where parallelization AND pools are severely discouraged. Perhaps in other thread.

Any sort of pool is centralization point. If I connect to P2Pool, my miner depends on data sent by that pool so I don't see where is the "improved decentralization" part of story.

You didn't catch the idea behind p2pool, did you? p2pool is a network of nodes, not a central server to where you call for getwork and send shares.

is it still feasible to invest 35$/month in a 12 core vps to mine yac ?

[relm9]

is it still feasible to invest 35$/month in a 12 core vps to mine yac ?

I don't think so. I'm estimating, but the average 12-core setup would probably get you around 3-4 coins per day. Let's say 120 coins a month best case. At current market rates that's 0.06 BTC, which isn't going to pay off that VPS.

And how would you fix that? There is no way to prevent 3rd parties from pointing hashpower to one node and use that node as miner connected to network.

Actually, Proof-of-Stake fixes that. When PoS will become active, we will see incredible PoW difficulty jump. This will kill centralized pools in the future, only p2pool-like pools can survive in such situation.

My YAC wallet refuses to start - any idea why?

My YAC wallet refuses to start - any idea why?

Take a look at debug.log file in wallet data directory (~/.yacoin/debug.log under *NIX, dunno about windows).

My YACoin wallet keeps saying "Checkpoint is too old. Wait for block chain to download or notify developers." I keep it running for, like an hour, and it's still showing this message at the bottom.

It's harmless. Get a client from this thread to make it go away: https://bitcointalk.org/index.php?topic=206577.0

Has anyone notice slowdown of transactions in YAC? Sent coins to bter near half an hour ago...still 0 confirmations



EDITED just after this message 4 confirmations in ~3 minutes passed  seems like network lag (or like YAC is afraid of bitcointalk)

Is there a current list of YAC pools?  yac.dontmine.me is gone, yac.ltcoin.net is down too often.  I've been using yacointalk's P2Pool, but I'm a fan of being able to see stats on my workers.  I see the networkhashesps has hit >111MH/sec, so I'm guessing there's another big pool out there.

Iam on coinme.pl too.

I hope there are more then 2 big pools.... (51% attack inc.)

Is there any pool working on port 80 or 8080?

Dontmine.me used to use that port, but now it's down.

My proxy won't let me use a different port  

[xchrix]

Also please update YAC Exchanges, today it's:
https://bter.com
https://vircurex.com
https://www.cryptsy.com

Pool yac.dontmine.me doesn't work anymore.

P2P pools:
http://pool.yacointalk.com:8336/
http://pool.bitcn.org:8336/ and http://yac.procrypto.com:8336/ - looks like the same pool with different DNS names.

http://yacpool.tk:8838/

Thanks.

CoinCasino.cc just added support for YACoin, if we could get that added as a gaming service. They have slots, multi-hand blackjack, and Dice Wars... and it sounds like they are going to be adding more games in the future. I tried it out earlier and it's one of the better crypto casinos I've seen, and just about the only place that does anything with YAC so far. Anyone else tried it out yet?
