[ANN][YAC] YACoin ongoing development

[sairon]

VERSION 0.4.2
I've noticed if wallet unlocked for PoS with

Code:

walletpassphrase <passphrase> <timeout> true

there's no need to confirmation for "Send coins" transaction.

Is it bug or feature!?  

ps: 0.4.0 asks passphrase in that case

Heh, guess we inherited this from the NVC codebase when getting up-to-date with their changes.

That said, it still is just security through obscurity as the private keys have to be decrypted anyway for PoS to work. One just has to extract them from the process memory and then steal the YACs. Tho it could be useful if you have the RPC interface exposed (which you shouldn't anyway ).

EDIT: Now that we're finally on Cryptsy again I wonder how long until the exchange rate of YAC regains its strength. Seeing that YBC is trading for 0.0048 BTC we should see some major up-trend.

2600 satoshi for YAC is horrible!

Seriously. There are a shit ton of exact/almost exact YAC clones out there that have not been updated for months that are trading at way higher prices than YACoin.
YAC needs a meme   

This sounds like a good idea to get things back on track...

Indeed...all those crappy clones trade for way more, like CPR, or YBC, ZCC...now UTC.

Which mobo do you use for 4x r7 240? Are you using extenders x1 to x16 or mobo with 4 x x16 pcie? I want to setup yacoin mining rig so I'm not sure which way is cheaper.

I use my main pc, which had an i7 3820 for yacoin cpu mining :p

X79-UD3 + i7 3820 + 2x4gb samsung 1600mhz cl11 + 850w psu (super overkill)

I'd reccomend a z87x-oc or asrock oc formula for 4 well spaced slots, no need for risers. Cards are single slot but not sure if the cooler fits without a slot in between, mine are spaced.

Was it interited from PPC via NVC and fixed by Sunny King? http://www.peercointalk.org/index.php?topic=1917.msg15070#msg15070

Some after-fork stats:

* latest block as of now

Code:

abe=> select block_height from chain_summary order by block_height desc limit 1;                                                                                                                       
 block_height
--------------
       429967
(1 row)

* number of orphaned blocks before the hard-fork

Code:

abe=> select count(*) from chain_summary where block_height<=420000 and in_longest=0;                                                                                                                 
 count
-------
 11345
(1 row)

* number of orphaned blocks after the hard-fork

Code:

abe=> select count(*) from chain_summary where block_height>=420000 and in_longest=0;                                                                                                                 
 count
-------
   335
(1 row)

* number of orphans in the last 10000 blocks before hard-fork - for comarison with the previous figure (off-by-one, i know )

Code:

abe=> select count(*) from chain_summary where block_height<=420000 and block_height>=410000 and in_longest=0;                                                                                         
 count
-------
   389
(1 row)

* total number of orphans

Code:

abe=> select count(*) from chain_summary where in_longest=0;                                                                                                                                           
 count
-------
 11680
(1 row)

* list of block heights where potentially unwanted forking occured since block #420000 (that is, my server saw the now orphaned block before the block that ended up in the main chain - regardless of the block's timestamp; block_id is the order of blocks as they arrived to my node - imo a much better metric than timestamps)

Code:

abe=> select a.block_height from chain_candidate as a full outer join chain_candidate as b on a.block_height=b.block_height and a.block_id!=b.block_id where a.block_id is not null and b.block_id is not null and a.block_height>=420000 and a.in_longest=1 and b.block_id<a.block_id order by a.block_height asc;

YAC rally on Cryptsy   welcome back cryptsy, we actually missed you 

Someone is about to regret their weak hands.

[xandebnu]

anyone know the command line to Scrypt R9 280x - GV-R928XOC-3GD

[Thirtybird]

Some after-fork stats:
*snip*

Look like good numbers to me.  330 Orphans in a week seems high until you remember it's a 1 minute block time with a relatively low difficulty.  The chances of two miners coming up with a solution at nearly the same time will be somewhat of a regular occurrence.

I'd asked about your block explorer before Sairon, but are you using a stock fork of Abe?  I'd love to have the blockchain info in a SQL database (Which is my native language), just never looked into it, and if you could save me any time, that would be helpful.

Yeah, I was just trying to find out whether my changes caused some unexpected forking behavior or not. So far it looks like it's working +- as intended.

Well... I tweaked Abe quite a lot, tho it's mostly some additional stuff like the graphs page and some new API methods and such. Most of the major changes are in my git repo here https://github.com/saironiq/yacoin-abe and I'll try to push some more when I get to it (sometime, maybe)... I believe the git checkout should work "out-of-the-box".

[00Smurf]

Does anyone have working nodes? I cannot get the wallet to sync at all. Using the new release version.

[Joe_Bauers]

I PM'd you a few. Are you running with the -noirc option? 

[cryptohunter]

where is the very latest official yac windows qt?  any active nodes?

Not the easiest way to communicate but its really popular among bitcoin enthusiasts.

Umm, just noticed I still had MtGox prices in profit calc and donations progress bar.
Fixed now (bitstamp prices).

I poured tons of money into litecoin when I was young and stupid last year, and I pulled out prior to the chinese boom I was banking on gox adding ltc... please, please die and never comeback, Gox. Thankfully, I refused to use it as of a couple months ago. Now we just need bter to disappear as well.

BTW I think there needs to be another YAC/BTC exchange. How about a YAC/BTC ONLY exchange?

Also, completely unrelated, I type walletpassphrase <passphrase> 999999999 true in the console in order to get proof of stake. Is there a different way other than leaving the wallet unencrypted? If not, we desperately need a more user-friendly interface in terms of proof of stake. Also, I can gauge what coins will be staked only by looking at send coins and then inputs, and I then look at time/date all my coins were received. There must be a better way for non-computer-savvy people... And can we interchange the term 'interest' with proof of stake?
