[ANN][YAC] YACoin ongoing development

[feeleep]

Hi,

As promised I opened 2 new LP ports on http://yac.coinmine.pl pool to handle the load:

8088 - not recommended - heavily used
8080 - not recommended - heavily used
8881 - recommended - new
8882 - recommended - new

Stratum Port: 9088 - recommended

umm... are you sure you're not just running into the default "socket max conn" limit? the default in linux is set to 128, which limits the number of incoming connections per one socket (one pool port) to 128, which is absurdly low. you can check this with

Code:

cat /proc/sys/net/core/somaxconn

or, if this is not the case, you must be getting some errors in the kernel log (dmesg) - if so, what are they? it's also possible you've reached max number of file handles per process (can be increased, too).

it is a problem with pushpool itself as it somehow keeps connections established instead of closing it (and yes - I am using block notify scripts ). After few days it is so overloaded (EDIT: sometimes there is 200000 established connections to yac port!) that there are more and more rejects - the only solution is to restart pushpool daemon.

There is no such problems with stratum server so thats why this is important (no only for me but also for miners)

IMHO that should be fairly easy to fix.
I can take a look after wrapping up the YAC client. BTW, already achieved massive speedup on startup - need more donations!
YAC price will surely spike after we release it, haha!

Yac price is recovering nicely...usd value has increased afaik.

Now I need to get a proper wallet, mine isn't updating the blockchain after a certain point

We have a working prototype of a new wallet ready. Not sure if it's bug-free, though. However, works for me so far.
You can get the latest windows binaries here: https://www.dropbox.com/s/pwa2lymjl6igh6q/yacoin-cc-latest.zip

NOTE: you NEED to move/rename (backup) everything except wallet.dat and peers.dat in the yacoin data directory and then run yacoin with -loadblock=C:\blk0001.dat (assuming you put the blk0001.dat file in C:\). This is needed because we had to change the way blocks are indexed and now the wallet starts in LESS THAN 30 SECONDS (down from more than 30 minutes). However, this initial load will take somewhere around 2 hours (still faster than downloading it through the p2p network).

If you don't mind redownloading all the blocks, you can just remove the unneeded files and start yacoin normally (less hassle, but takes more time).

I downloaded the new client and ran it using the switch but yacoin still hasn't opened after 15 minutes.

[ivanlabrie]

Thanks Sairon! I'll try it out now...  

EDIT: wow! 30 sec indeed...downloading blocks now. Thanks man!

Well, it should take a long time at first, read the note carefully.

Glad it also works for you.


Tips for me and my friend who helped me write this appreciated!

after the client came up I closed it and opened it again.  This time it opened quickly and some coins went to stake properly.  Previously I'd had an orphan stake.  This looks good.

Nice, thanks for the feedback!

This was posted in the other thread, but figured it might have been missed. Certainly sounds like something we should be in the running for!

Hello there,

Reddit ALTcointip bot has just announced its 2nd round of signups for a list of supported cryptocurrencies.

Please see the announcement for details. Thanks!

This is great stuff!  I'll have to download and send a donation when I get home.  This is going to save so much time!

CPU Miner supporting scrypt-chacha on stratum

I was able to use the stratum version of CPU miner from pooler, and found the optimizations in the scrypt-jane library that mikaelh made, and I fixed the bug that prevented shares from being found and was able to compile them all into a series of x64 binaries for Windows.

These binaries should be as fast as the ones that you've been using, and also support stratum.  I kept the "scrypt-jane" command line option - apparently changing it to "yacoin" just confused people (even though it's, well, wrong).

Please, post any feedback or any problems.  PM me as an option.

Latest release will always be here - https://mega.co.nz/#!mwZTnTJD!M6V3Vnmj2Kxz1fhDP8K2LUFXjrtjM-OIcAoJS0S5afw

Source is available as well: http://github.com/Thirtybird/cpuminer

I saw yacoin got a healthy upturn but because I can't mine yet are there any nice sites or faucets I can earn my first yacoin? I am going to buy some also on crypsy tomorrow too but wanted to earn my first yacoin.

Cracked it!!!

Hi

It works perfect! So here is the message:

Please use Thirtybird's cpuminer to mine on http://yac.coinmine.pl pool to get 5% less stales

Code:

minerd-avx -a scrypt-jane -q -o stratum+tcp://yac.coinmine.pl:9088 -O worker:worker_pass

PS. I will send some donation later

Yes, there are many ways to get your first YAC:

Buying at excanges: (I think this is the best way)
bter.com
cryptsy.com

Mining:
Simple: A new (not official I think?) version of yacoin-qt that supports single CPU-mining)
Standard mining

If you want to work for it:

https://bitcointalk.org/index.php?topic=311379.20 (Impossible, but as example what can be earned, already done by sairon)
Sairon made some serious YAC by bounties and I'd like to see some competition here.

or one of the many giveaway threads:

https://bitcointalk.org/index.php?topic=211053.0;topicseen(not mine, not sure if still working)
there is also one at yacointalk.tk

There are currently no faucets working, but I have planes to lauch on in a few weeks or so.

Updated the logo on my block explorer and also on yacoin wikipedia page. https://en.wikipedia.org/wiki/Yacoin
Also, windows binaries available with the new logo https://www.dropbox.com/s/pwa2lymjl6igh6q/yacoin-cc-latest.zip

Sites that need to change the logo:
yacoinwiki.tk
yacoin.org

At least let's be consistent.

*grumble* I still like the old logo more.

Nice.. Logo looks a bit low res. Is that the best quality version we have of it?

I'm sure someone has an SVG version of it. I just uploaded the biggest PNG I found.
