Re: Bitfinex owners - stolen funds and ponzi schemes

They no longer operate out of Hong Kong -- it's just a mailing address for their attorney at this point.  Previously, when they did, the name of the company with the Bitfinex licensing in HK was "Renrenbee Limited."

That said, their holding company and major incorporated interests are registered in the British Virgin Islands as offshore companies, their servers are hosted by a datacenter in Italy, and their back office functions moved to Taipei, Taiwan earlier this year.  Their primary bank relationship is in Taiwan, as well (CATHAY UNITED BANK).

You can't simply "call Hong Kong Police hrrr derrrr" to figure this one out. It's a little more complicated than that.

try to dial back you intensity till your hashrate starts to drop
sometimes if you set it too high you will get stale shares
that worked! It seems that sg5 doesn't necessarily work well with all the settings I've used in the past with the older 4.0.1.

thank you!  Smiley

edit: silly question but you are setting your username right?
edit2: err why do you have "failover-only": true, twice and
"extranonce-subscription": true,
"no-extranonce": true,
maybe that is why it doesn't work...
you tell the pool to use extranonce subscription then turn it off?
Alright, I removed both extranonce lines and the second failover-true line.  (they were left in from a copy/paste I did of someone else's working conf).  I then found an error in a username entry...

GOT IT WORKING!  THANK YOU!!  Grin

Those ports may be closed if nist5 is the most profitable, which it has been for the last day or two.

All you have are profitability ports, with no fixed port as a failover.
How do I add a fixed port as failover?  What would I need to add to the above?

EDIT:
I just added this pool to the list:

Code:
{
"name" : "nist5 failover",
"url" : "stratum+tcp://east01.us.trademybit.com:7770",
"user" : "xxx",
"pass" : "x",
"profile" : "nist5"
}

Still get the same URL error for all five. Sad

You can just search for your "lol" address on blockchain.info, just take away the prefex:

https://blockchain.info/address/1BSKaQZ6Bn7fZG8iuViQtMSnN3UPk9LHYM

You've received 2 transactions. The first was from me for 100 lol, and the second was from someone else for 10 lol. To check if amounts are right, just look at how much was sent to your address. For example, I sent you 0.006 BTC, and if each lol is 0.00006 BTC, then I sent you 100 lol.
Cool, I got it.  (It's not often I wake up to extra random coins! LOL)  

thanks for helping me figure out this new toy!

Someone did in fact send you 10 lol-colored coins after the initial 100 that I sent you.

Check out the transactions on blockchain.info - I believe the balance you have is correct.
That would make much more sense!  Noob question: how do you find these CC transactions on blockchain.info?

New build:

Linux 64-bit: http://killerstorm.xen.prgmr.com/alex/chromawallet-linux-x86_64-0.0.5.tbz
Windows (32-bit): http://killerstorm.xen.prgmr.com/alex/chromawallet-win32-0.0.5.zip

Now if your wallet got "corrupted" like mentioned above, you can do "cw-cli full_rescan" to repair it. (It takes about 10 seconds.)

I haven't addressed the root cause yet, though.

alright, your process worked and helped me recover both the GUI and the assets.  However, there is one very interesting NEW problem.

The transaction that initially broke the wallet and the GUI was a SELL order for 10 of my 100 total "LOL" assets I had in my wallet at the time.  Based on the error log I posted earlier, you stated that you couldn't find the TXID it was looking for -- which I assume may have caused part of the problem I was having.

The NEW problem I'm referring to:  My recovered wallet now shows 110 "LOL" instead of the original and expected 100!  Somehow, some way, the broken TX ended up adding 10 of the "LOL" asset to my wallet even though I did NOT place a buy order -OR- the alternative explanation is that someone may have directly sent me 10 more "LOL" since the last time I successfully opened the wallet.  Is there a local log of received TX I can look at?   (speaking of which, a "Transaction History" tab would be great! Wink)

Using the Win32 client, it looks like I somehow broke it already.

Well, it has some loose ends... This happens if you received a transaction server doesn't know about. We need to handle this error without blowing it up.

However, I see that transaction 902a7fb4b56e291b194a1aa5ef87190e1d658a84a4f787edbe7325bf17889719 is being requested, and I can't find it anywhere. Might be transaction malleability issue, I dunno.

Any ideas on how to recover?

Well, you can delete coin_data entries in wallet, but it's probably easier to wait for a fix.
What exactly am I deleting with those entries?  Would those affect the assets I had, or would those remain intact?

I have the file backed up (post crash), so I guess it's worth a shot.  If it doesn't work, I'll wait for the fix.

Thanks for your efforts!

PS:  trying to create a new receive address on the receive tab doesn't appear to work either.  Nothing happens when you try to do so.

I tried it from a fresh install and it works great; but, as soon as I copy the mainnet.wallet file over from the broken install, it fails to load the GUI and puts out the above errors in the terminal window.

The GUI first broke when I tried to place a SELL order on the P2P Trade tab.

Any ideas on how to recover?

Re: Bitcoin Security Standards Audit [BSSA]
by

on 05/03/2014, 06:21:45 UTC
There may need to be a hybrid approach, or perhaps an entirely new compliance organization started with Bitcoin developers and security experts.  As an example of such an individual, Andreas Antonopoulos recently did security checks for companies like Coinbase and Mt. Gox.
I tweeted Andreas the other day with a similar idea following his audit of Coinbase.  Unfortunately, he never responded (I definitely respect that he's a busy guy, so I won't hold that against him... lol).

My idea is to solicit the community for experts to step forward, be vetted by the community itself, and then get selected at random to participate in such audits.  I haven't fleshed out the entire concept, but it seems to me that this type of voluntary self-regulation would be a perfect fit for the bitcoin ecosystem.

I'd gladly throw my hat (and my resume) into the ring if this idea gains reaction.

I apologize if I didn't give credit where credit was due.  I actually don't know who first noticed Willy nor do I know who named him.  The only place I've read about him is in the Wall Observer thread, so yes I was too quick in assuming that fellow Wall Observers were the first to notice him.

But your Reddit posts says its from "about a month ago."  Weren't we talking about Willy in December on the Wall Observer thread?  Does anyone remember when exactly the web and API interface went down and we watched Willy execute trades all alone?  Wasn't that November or December?  Were we calling him "Willy" at that point?
The discovery of the bot actually happened in December, yes.  I had briefly described it during a live broadcast as a guest on Bonavest's trading show.  It was also during a later broadcast that I took suggestions for a name.  One of the other guests listed "Willy" as an option, so I later chose that one as the best of the bunch.  From that point on, the name stuck. (It's kinda cool that it spread to everyone, LOL)

Check out the reddit thread I linked and you'll also see that I'm the one who captured and shared the screenshots the night the trading API went down.  That was when I decided that it was highly likely that Willy was owned and operated by Gox itself.  (A fact that I also shared on another live Bonavest trading show, as well as other places like tradingview.com)

Interestingly enough, I confronted neotufur (sp?) in the #mtgox channel on IRC about the bot a few weeks later, and he (or she?) adamantly denied the fact that the bot belonged to Gox.  His explanation for how the bot could trade when nobody else could was something to the effect of: "if you have enough money, you can buy a direct privileged connection to our servers, so that's probably how the bot kept going when nobody else can trade."  He then called me crazy for believing it belonged to Gox and almost banned me from the channel!  (I'll try to dig up the IRC log for ya... it was amusing as hell!)

Whatever the case, I meant it when I said that it's no big deal.  I really do like how you summarized the role that Willy might have had in this mess, and it's definitely plausible!

Edit:  Here's some of my screenshots from when the trading API went down on January 7, 2013, but Willy was still making trades for the next 90 minutes while it was down for everyone else: http://imgur.com/Ub46sWE
and another: http://imgur.com/wyW1g4p

Regarding the discovery of Willy, it wasn't "Wall Observers," whoever that is...

I discovered and named him. My original thread here:
http://www.reddit.com/r/BitcoinMarkets/comments/1uhjrb/intriguing_bot_activity_on_gox_for_the_last_2

Not a big deal, but kinda rude to take away what might be my only contribution to the upcoming Mount Gox movie... Smiley

First thing don't worry your coins are not lost.

I had half a billion in limbo for a week and only got them back yesterday after i filled out a ticket.

Fill out a ticket and have the transaction id ready with the address you were sending it too, amount of coins too.

Don't worry, we have all been there. and i don't have a working block chain link.
Thanks for that encouragement!  but, does that mean that there isn't a working blockchain explorer for this coin?  that ain't good... lol
