WOW 100 percent jump ! go YAC go !! Cheesy

Followed by an istant drop back to original prices ...  Cry

The spread is insane on YAC. After the last time I logged in I bought 10kYAC @ 0.05mBTC and could have sold them at 0.1mBTC even befor logging in again today. It hasn't been decided yet where it wants to go, but if it wants up it will be damm fast. 25kYAC market buy on cryptsy or bter and we'd quadruple for that moment.

yeap shame.. 
I buy every small dump I have funds for, this is the least thing I can do for YAC, but seems like rarely anybody fallows..

"Followed by an istant drop back to original prices.. "

"problem" is that even at that price YAC is more profitabile then LTC, so miners just dump it.. this prevents price to really rise like somedays..

Paperprofits on high value with no volume are just illusional. The 100million painting that noone would actually buy isn't really worth much (unless you have a good fire insurance).

I rather have a cheap crypro with lot's of miners/PoS dumping than a high valued one without. It is a very good feature of YAC that it has such a huge supply compared to other cryptos. Unless the marketcap isn't ridiculously small it makes it far more useable as currency than most other cryptos.

You have some fair points here, agreed.

Dunno, prolly because of that 2 and something hour period without blocks yesterday (or the day before? i don't remember). it looks ok now, though. haven't analyzed what exactly happened, yet. i plan to look at it sometime later.

I don't know what it was but it resolved itself pretty quickly and by itself from what I can tell. I do not believe it was a ford at all or we would be hearing it more from people affected. Any further ideas? I only noticed it when Cryptsy stopped the trades for a few hours.

The vote for the new logo is at:

https://bitcointalk.org/index.php?topic=288824.0

Actually I thought we had already agreed on Beave162's version, but it seems we're getting a total different one. It looks like most people that voted on the first vote also got to the new thread, but some might not heard about it. Hurry up if you haven't.

I've asked all of the pool operators that I know of to upgrade to the latest stable version which has updated checkpoints.
Everyone else that has the ability to upgrade to the latest version should probably do so as well.

I have no more ideas or possible solutions. You might find fix if you post about the issue on Bitcoin Technical Support part of forum or check for
fix on this forum and elsewhere on Internet. There are programs for wallet management, one of them is called pywallet or something like that.

My version of wallet is v0.4.0.0-g32a928e-yac-wm-alpha, it is sairon's latest Coin Control 32-bit version. Check if it works with your old wallet.dat

https://bitcointalk.org/index.php?topic=276948.0

Actually, it did work, but now it stops ~35000 block and when I tried to rescue some confirmed coins by sending them to the address i got the message: Microsoft Visual C++ Runtime Library "This application has requested the Runtime to terminate it in an unusal way. Please contact the application's support team for more information."

Reinstall Microsoft C++ Runtime for your OS or just export private keys for addresses that have coins on them (use Coin Control to check that),
create new wallet and import private keys in it.

Help > Debug window > Console tab

Code:
dumpprivkey address
importprivkey privatekey addresslabel yes

I made it! Got myself a new address, and now everything works just fine! Thank YOU!

The poll has concluded with C being the chosen logo.

I have to say it again, thank you Mjbmonetarymetals for designing logos C & D. The two together almost have 70% of the votes.  Smiley

Out of curiosity, what is this saying that suggest an attack is going on rather than just people mining? I'm new to cryptocurrencies.

As an attacker you mine on your own chain for a while (without broadcasting it to all the others), then suddenly add your blocks and so overrule the legit chain. All transactions on the legit chain while that period will be reversed so you can buy stuff without actually loosing coins.

Well, this might not have been intentional. Someone could have had a lot of PoS blocks found all at once or some PoS blocks were not broadcast to all nodes (and with PoS having a higher priority than PoW, they easily overtook the chain). Also, this was happening a lot in the early days of YAC (diff = 0 and stuff).

The replacing blocks were AFIK all PoW so this isn't just a minor coincidence. It's either a attacker that wants to harm YAC or a serious bug. None of that should be taken too lightly. We will see.

Can anyone check if there were some reversed transactions?

Nope,
Code:
11.9.2013 16:54:36 REORGANIZE: Connect 1 blocks; 00000007c5835b4968bd..547db4922a8b8e71ff85
was a PoS block that wiped out 34 PoW blocks. (You see it's a PoS by the hash's first bytes - 547db4922a8b8e71ff85 - no leading zeroes = very lwo difficulty = PoS block).

Can anyone check if there were some reversed transactions?
Surely there were some (if not all). I would advise exchanges to wait for at least 60 confirmations (or even 120 to be safe) before crediting funds to accounts as they are the most likely target of these attacks (if they even are attacks). Most likely this was just someone syncing their client while minting PoS blocks (haven't checked the code yet, but it's entirely possible that the PoS minter is enabled even before fully synced - or it might have had believed it was synced while it was 34 blocks behind [which is not a lot, since we have 60 second block target]).

IMHO the blockchain cummulative work calculation formula should be changed to something more sensible, eg. give PoS only a slightly higher priority than PoW. This would massively reduce such reorgs as seen in the posts above.
