Quoted. Just to prove for future use (forum allows to edit messages, so the date of message does not prove anything)
Here is another hash (this time XT/BIP101 related):

The date of a message becomes underlined if it is ever edited. If you don't edit a message, the timestamp is quite reliable. Someone with direct database access could have edited the message, but not a regular account owner.

"Addresses", afterall, are nothing more than a cryptographic public key; despite the community commonly calling them otherwise.
These public keys are assigned to specific users and could be considered much the same as an after-hours drop box.

Unless an exchange specifically enumerated otherwise in their Terms-Of-Service, I think it is reasonable to assume that a customer might have a legal expectation that assets arriving at a cryptographic key assigned to them, be attributed to them.

I don't see it that way.

Consider this example:

You owe me money, so I give you my address to send payment to. You send the money, it arrives at my address. If someone else eavesdrops on our transaction and sends another payment to my address for fun, that's free money for me. You have no claim on that payment. It went to my address after all, and is nothing to do with you.

I think the confusion comes when people think in terms of "my deposit address" at an exchange. The deposit address is nothing but a hash of a public key in the exchange's wallet. It's owned by the exchange, not the user, since the exchange are the ones in sole control of the corresponding private key.

You can argue that it's good PR for the exchange to share the free CLAMs that you gave them, but I really don't think you can make a good legal (or even ethical) argument that they have a duty to do so.

I can't say for sure, i do know i made a direct auto withdraw to an exchange (dogecoin is in question) so it could be any of them , since they all changed deposit addresses.
I mostly used cryptsy bittrex and poloniex . If i find more info on it, ill post it here, but i definitely consider the issue unmoral from exchange sites who did cash in on clams.

I expect it was poloniex then. They dug up all their CLAMs early on and held a giveaway to distribute the CLAMs to their users.

Check the timestamps when the CLAMs first moved. That will be a good way of telling whether it was poloniex or not, because I'm sure someone will know when they did their digging.

Be careful with this site, they store balances in satoshis and do not account for smaller units.

This means that if you bet 10satoshis at 1.05x, you will profit 0satoshis if you win, while you were supposed to profit 0.5 satoshis.

This may not seem like a big deal, but it goes to show how unprofessional the site is and how the owners have not clue what they are doing. No other bitcoin gambling site (PRC, PD, JD, etc...) stores balances in satoshis, they all have smaller units, because with small amounts you often need to work with fractions of satoshi in order for things to balance out.

I don't know about the others, but JD definitely rounds down. If you bet 1 satoshi at 50% and win, you won't win anything. Your profit is calculated to be slightly less than 1 satoshi and rounded down to zero. There's a warning up the top telling you that the profit is zero:

I know dooglus had been known to look ahead from time to time but stopped when he accidentally gave up information to a better.

I don't think I ever accidentally leaked any information. One time I told a player that I had looked ahead while he was playing at very low chance of winning, so see when he was due to hit. And he freaked out on me. He told me that just by knowing his future I was changing the future, via quantum effects. So I promised I wouldn't do it any more.

Not looking makes it much easier to be in the chat. Sometimes people on long losing streaks try "fishing" for information from me. "I'm bound to hit soon, right doog?" - if I knew the answer to that question it would be difficult to know how to answer. It becomes a game of poker - do I bluff, double-bluff? And so I don't know - then I can't accidentally leak information.

On the other hand, if PD had changed the server seed of hufflepuff/robinhood they wouldn't have lost a few hundred bitcoins. Wink

I don't think so. HufflePuff had a way of discovering his server seed. If PD had changed it, he would have just made a new account and continued cheating on that one.

yeah i should have doog from just dice stop in and he can let you know really how big of a deal it was when he had to reset the server seed and what he did to make sure the EVERYONE new that they werent using the same seed...

I found the thread accidentally all by myself.

Us dice site operators all get a little 'spooked' sometimes, and I think it's good to err on the side of caution. It's not a good idea to accuse people of cheating though, as BTC seems to be doing in that chat log. If the player isn't cheating, there's a good chance you'll offend him enough that he stops playing and so never loses his winnings back to you. And if he is, he'll just deny it anyway.

I was once concerned that server seeds may have leaked, and so even though I thought it unlikely I couldn't take that chance, and decided to reset all the server seeds. I made the site act as if all the players had clicked the 'randomize' button, resetting the server seed, revealing the old one, resetting the nonce to 0, etc. And I made the chat tell everyone about the reset each time they logged in, and every 10 minutes thereafter. For a month or two. Until people begged me to remove the notice.

is more time i see this problem to dadice.
i have satoshi to account, click to bet, rollin for xx second, later rollin stop, don't appared a bet in my stat, but i have lose my satoshi. Why ?
i have register a video and add to youtube

https://youtu.be/wzO_-9mWiSQ

Happened to me as well at least two times.
The biggest problem is that you have no betting history and can't look up what happened...
Dadice is just too laggy...

Have these been resolved? It's one thing if a network issue causes a bet to 'hang', but if the player isn't then able to verify the roll to check there was no cheating, that's no good.
2587  Bitcoin / Development & Technical Discussion / Re: Bitcoin private key/wallet.dat data recovery tool! on: September 16, 2015, 05:43:41 AM
So this morning I noticed there was an outgoing transaction in my wallet that hadn't confirmed for a week. I decided I would try to send it again with a bigger fee. So I did a 'dumpprivkey' on the address that funded the unconfirmed transaction, made a new wallet, did an 'importprivkey' to import the address into the new wallet, then re-sent the transaction. There was only a single output on the address, so it used the same one again, effectively double-spending it.

Once the transaction confirmed, which it did quickly, I switched back to my main wallet, and deleted the temporary new wallet, since I was done with it. Right?

I rescanned the old wallet, using the -zapwallettxes argument to delete the old conflicting transaction, and it came up showing that I had made two spends recently, not the one that I expected. Then I remembered: the change from the new spend is only in the new temporary wallet that I just deleted.

Oops.

I looked for 'undelete' programs, but didn't find anything that looked useful. I found this thread, but the git repository seems to have died. So I wrote my own simple "privkey finder":

Code:
#include <stdio.h>

main() {
  int c, i;

  // privkeys are preceeded by: 3081 d302 0101 0420 and are 32 bytes long:
  while ((c = getchar()) != EOF)
    if (c == 0x81 &&
        getchar() == 0xd3 && getchar() == 0x02 && getchar() == 0x01 &&
        getchar() == 0x01 && getchar() == 0x04 && getchar() == 0x20) {
      for (i = 0; i < 32; i++)
        printf("%02x", getchar());
      printf("\n");
    }
}

It's much simpler than the tool this thread is about, but it did the trick. It found the deleted private keys and I was able to get my coins back.

So I figured I'd share it.

I built and ran it like this:

Code:
$ gcc -O4 -o pkgrep pkgrep.c
$ df ~/.bitcoin
Filesystem      Size  Used Avail Use% Mounted on
/dev/dm-1       901G  497G  359G  59% /
$ su
Password:
# ./pkgrep < /dev/dm-1

I was somewhat surprised to find that the private key for the change address was on the drive 5 times. It was a new wallet that I created just to double-spend that single output, then deleted. And somehow the key found itself written to disk 5 times.

Isn't this insanely beneficial for exchanges since they hold vast amount of addresses that their users used to deposit btc/ltc/doge ?
I have skimmed over some of mine, and clam has been claimed on them, which proves this ?!

It's insanely beneficial for exchanges and other services that didn't keep their wallets tidy.

I was running Just-Dice at the time of the snapshot, but regularly swept coins from deposit addresses to a single offsite cold storage address, so the Just-Dice hot wallet received very few CLAMs.

It's kind of a shame that the initial CLAM distribution rewarded those who practiced poor wallet maintenance. But what can you do. Smiley

Probably already asked a lot but can't find it that quick.

Is it safe to import a wallet which is still in use?

Importing a wallet basically makes a copy of it inside the CLAM wallet. So if anyone ever manages to get a copy of your CLAM wallet, they will also have access to any coins in any of the wallets you imported into it. The official version of the CLAM client itself doesn't take advantage of that, but someone managing to get a copy of your CLAM wallet could do, as could a rogue unofficial version of the CLAM client. So recommended standard practice is to empty and retire your wallets before importing them into the CLAM client.

Why is selling account bad? What if you get one as a loan collateral?

I don't lend any money nor do I care about receiving any accounts as collateral. It's an unethical thing to do IMO and people scam using bought accounts. Hence I consider it bad but the forum allows it.

I wouldn't call it unethical. Otherwise every pawnshop owner in the country, who is lets say, taking in a $20,000 Rolex watch for $5,000 and sell it if you default to pay back for $12,000 would act unethical as well. A collateral for a loan is a collateral that can and should be used in case a loan is on default.

I think the unethical part is if you sell an account with 'trust' intact. The new owner receives an account with positive ratings and may as a result be trusted by people thinking he actually earned those ratings rather than simply having bought them.

Instead of pawning Rolexes, think of pawning diplomas. The new owner looks as if he has worked for something whereas in fact he only bought a piece of paper.

guys how do i -reindex wallet Huh
when i type -reindex on console it says "method not found" ??

Run the client executable with the -reindex flag.

In Windows that probably means either using the command line cmd.txt tool to launch it:

  clam-qt -reindex

Or editing the properties of the shortcut you use to launch it, and adding -reindex to the target.

I just found out i had 13.8 CLAMS, is staking feasible with this amount?...

Move your mouse over the ticket icon on the bottom left corner of the clam client.  It will pop up a message on the expected stake time. 

The network weight is currently showing as 742000.
Divide that by your number of CLAMs to get a number of minutes per stake.
Divide by 60 and 24 to get an expected number of days to stake.

I get 742000 / 13.8 / 60 / 24 = 37.33 days.

So it's "feasible" but probably not worthwhile unless you were going to be leaving the computer on all the time anyway.

I would never reverse transactions to gain a competitive advantage. That would be an abuse of my power. I'm sure you don't really think that I would; there's a huge difference between attempting to prevent you from taking advantage of JD's trollbox to advertise your competing service and using JD's position of majority stakeholder to manipulate the blockchain.

You wouldn't, but the FEDS (or mob or underpants gnomes or whoever) who take over your computer systems will or could (if ever.)  The chain is only as strong as the weakest link and by your power tripped blurred judgement it will result in a lot of people getting fucked I fear.

Your point doesn't make sense. You say I should take a cut of your profits from charging people to dig their CLAMs so I won't be tempted to manipulate the blockchain. I say I'm not tempted to anyway. You say no, but the FEDs would! If so, they would whether or not I'm taking backhanders from you.

Not advertising that your casino digs CLAMS isn't being deceptive.  My sites target is intended for Crypto users of all ages and you have no way of keeping children off your site... I've seen a LARGE number of players recently who have openly claimed to be underage and no one steps in to see them to the door.  Everyone is to busy worried stopping loans and banning faucets.

I ban anyone I see saying that they are underage. The reason we don't like people asking for loans is that more often than not it ends up with the loan never being repaid. And I banned your faucet site because it's basically a giant ad for your overly expensive digging service.

Our fees are clearly labeled... just like yours are on Just-dice.

I have been unable to find any mention of your fees on your site.

Dean you have yourself a nice day and lets not throw rocks in glass houses. I will not be responding further & nothing personal.

I'm unclear as to why you called me Dean. I have a few theories, but can't decide between them:

1) You accidentally mistyped.

2) You think I am Dean from PRC dice; that seems unlikely since in the past you and I have had fights with Dean over various things. It would be weird if I was him.

3) You think I'm acting like Dean in some way. He's pissed you off before by not paying the commission he owed you for referrals for instance. Maybe by not letting you advertise your site in the JD chat you think I'm similarly depriving you of your due.

4) You're trolling.

I guess it's probably 3, but I'm not sure. I don't see how you could reasonably expect that I would let you advertise such an unfair service on JD.

It is not against any rules to sell your account. If the person sponsoring the sold account still trusts the ratings of that account then there would be no reason to remove them.

If I sell my account, not only does my existing feedback stand, but also any future feedback made by the new owner will appear for everyone, as if the new owner is trusted when he shouldn't be.

I don't see why it wouldn't be against the rules for people to trade accounts. The main reason people do it seems to be to buy and sell trust.
2596  Economy / Marketplace / Re: YOU ARE ENTITLED TO A REFUND if you used Quickseller/Panther52 as an escrow on: September 14, 2015, 11:47:29 PM
Is Panthers52 also a Quickseller account? What if we used either for escrow for a goods purchase (not lending)? The above comment was made but no one confirmed that Panther and Panthers are the same...are they?

Quickseller, you're a sneaky one with all these alt accounts! I dealt with Panthers and I think you might have responded from both accounts in the thread, wtf?!

Quickscammer and Panther52 are the same person, along with many other accounts.

If you have a link to the thread where QS and Panther52 were chatting to each other, that is very helpful in determining QS's honesty.

Here's Panthers saying that he's for sure not QS:

If you want proof of who I am then review this video[NSFW] and you will see for sure that I am not QS and who exactly I am.

Kind Regards
Panthers52

Here's QS referring to Panthers as "someone else":

Just finding out about this now.
 if true, then it should be extended with a small grace period

It is your auction, although this happened to someone else as well at roughly the same time and they ended the auction:

The same happened with me. This means that I am going to have to take the loss, as I took the risk associated with having an auction.

I also found this (in a locked thread so I couldn't quote it) where the two accounts seem happy to let people believe they are different people:

If the wallet has been emptied prior to claiming the risk is no different than importing any other random set of characters.

Also don't use that wallet again afterward. Most wallet.dat files include preallocated keys, so future use could (and likely would) involve private keys that were exposed to the clam importer.

This exactly. We usually recommend that you "empty and retire" your wallet before using it to claim CLAMs.

Doing so protects the CLAM developers as well as yourself. If you use your old BTC wallet to claim CLAMs, then continue to use it with the Bitcoin client afterwards and somehow manage to get your computer compromised and have your coins stolen, you'll never been 100% sure that the CLAM client didn't do something sneaky with the wallet you gave it. If instead you retire your old wallet and switch to a new one, you can't blame the CLAM client when your new wallet gets compromised.

Of course, if you're going to be downloading random executables from the Internet and running them on the same machine you use for your Bitcoin wallet, you're going to end up having your coins stolen anyway. But that's a separate issue, and more about practicing safe computing than anything about the trustworthiness of this particular client.

Vod & dooglus most likely know each other IRL. So, dooglus will never remove Vod.

I've PM'ed him maybe twice - once when I first added him to my network, and again when there was some discussion that he was throwing around negative trust too lightly. But it turned out that the people he was leaving negative trust for almost always turned out to be scammers.

Other than that I don't know him. I certainly never met him in person.

Theymos is more intelligent than most of the people here. He knows Trust system can not ever be perfect. But, he needs to have one to manage the unruly mob. Moreover, he has successfuly created a trust market.

How does a "trust market" benefit Theymos? I don't understand your point.
2599  Other / Meta / Re: QS joins Tradefortress in the realm of the completely discredted, Wardrick next? on: September 14, 2015, 08:15:14 PM
Selling your account is not reason to be removed from DT.

How does that make any sense?

If I sold my account I would absolutely expect it to be removed from DefaultTrust.

The new owner should need to build their reputation rather than being allowed to buy someone else's.

I can see that it makes sense not to remove old negative trust when it appears that an account has been sold, because otherwise faking an account sale is an easy way for people to clear their negatives. But allowing positive feedback to stand after an account sale makes no sense as far as I can see.

There have been other known sold accounts that have been allowed to remain on DT

Again with the "those other guys did it so it must be OK for me to do it" argument? That is faulty logic at best.
2600  Economy / Gambling / Re: MoneyPot.com :: The bitcoin gambling wallet on: September 14, 2015, 07:53:34 PM
thanks again for your input but it looks like that we have a misunderstanding regarding zero risk bet for the app owner and Investors

Yeah, I posted before I had read to the end of the thread. I hadn't considered bets where the player could lose but not win, like betting both red and black on roulette.

please let me ask again my question why should an app owner split 50/50% this 2.7% for this zero risk bet
with the Investors.

Well, the bottom line is "that's how it is; it you don't like it don't use the service".

But note also that the investors are getting a pretty rough deal at moneypot already. Most places they could invest only take 10% of their profits. There's no "app" to pay, only the site which takes a commission. Most places take just 10% of investor profits. In other words the invest gets 90% of the house edge and the site gets just 10%. So I don't see what grounds you really have to be upset when you "only" get 50% at moneypot.

As I understand it there are a few exceptions to the 10% commission rule : bitdice takes 20% and PRCdice takes 25%. But even PRC's 25% is still only half of what moneypot is taking from investors. Here's a chart for comparison. Compare the thick red line (investors at moneypot) with the three horizontal thick lines at the top (JD, BD, PRC) - for all but the biggest bets investors at moneypot do much worse than at the other places:



I suspect that the reason investors get 50% of no-risk bets is because Ryan is aware of how they can do better elsewhere and wants to make moneypot a more attractive proposition for them.

everyone should be allowed to share his opinion.

You are allowed to share your opinion, and so are the people who are telling you that they think you are wrong. What's the problem?
