2101  Bitcoin / Development & Technical Discussion / Re: Bitcoin URI on: July 28, 2012, 02:22:23 AM
The bitcoin URI specifies the following query parameters:

  label: Label for that address (e.g. name of receiver)
  address: bitcoin address
  message: message that shown to the user after scanning the QR code
  size: amount of base bitcoin units (see below)
  send: used to send bitcoin, rather than to request them

It would be nice to add another parameter called singleUse (or something shorter) to indicate to the wallet that the bitcoin address should not be retained for future use.  At bitpay we see a few cases where people accidentally send coins to an old address…it would be nice if the addresses we present aren't retained in the senders wallet to prevent this from occurring.  It would also be nice if wallets didn't automatically remember any address unless explicitly requested.
Bitcoin supports a req- prefix for important fields. Simply add req-singleuse=1 to the URI, and non-conforming clients will ignore the URI. Conforming clients will not retain the address for future use.

The problem will not be solved until the Satoshi client implements singleuse, but this will completely remove the possibility of error.

2103  Economy / Games and rounds / The "RALLY!!!!" or "CRASH!!!!" game (Pilot round) on: July 28, 2012, 02:12:04 AM
This has died.
This is a pilot round, to test a concept. No BTC is collected nor payed out in this round.



Do you know exactly where the price is going to go, but for some reason can't use an exchange? Does leveraged trading make you yawn, but gambling makes you feel like you're twenty? Well, now you can speculate without ever touching an exchange!

I've thought up a simple game that allows people to bet what they want (just like real day-trading), but at a much slower pace, and a much more open environment. Effectively, this game converts the skill of day-trading into mostly luck, while retaining the "speculate right to win" atmosphere. The more BTC bet on a certain outcome, the less that can be won on that. This should wipe out any market influences, but not the choice involved in day-trading.

However, as with many games, these tend not to be popular. They also tend to eat up a lot of the manager's time, looking through blockexplorer for hours on end. So, I've decided to try a (shortened) pilot round without any actual BTC. Just post your bets after reading the rules. Since there's nothing but time to gain and lose, suggest whatever and ask whatever questions you wish in this thread.

If this doesn't work as well as I hope it does, obviously I won't try to manage it when real money is involved. I do have a contingency plan though: this could be moved to Speculation or Off-Topic and be based on fake "market guru" points instead if it doesn't. But first, let's see if it does work.



First, some definitions:

Weighted average price on {date}
The price that bitcoincharts lists for Weight Average in its daily data table for Mt. Gox USD on {date}, in bitcoincharts's UTC time. This is the average of all trade values over the day, weighted by volume. Note that this field is rounded to two decimal places, and those are all the decimal places used for any calculations.

One-day change from {date} to {date+1 day}
The change, expressed in percentage, given by the following formula:

Code:
(Weighted average price on {date+1 day} / Weighted average price on {date}) - 100%

Rally
A one-day change from a date to the next day that is strictly greater than 1.27%.

Crash
A one-day change from a date to the next day that is strictly less than -0.46%.

Sideways movement
A one-day change from a date to the next day that is between, and including the endpoints, -0.46% and 1.27%



Next, the rules. For each day-to-day change over a week (I'm planning on weekly rounds), there are three addresses to send to1: one to bet on Rally, one to bet on Crash, and one to bet on Sideways movement. Any amount greater than 0.0005 BTC can be sent to these addresses (amounts less than 0.0005 BTC will not be returned), and will count as a bet for the amount sent, decreased by 0.0005 BTC (to ensure transaction fees are paid for, and to compensate for my time). Bets will only be accepted if their first confirmation is in a block with a timestamp predating the day without a clear weighted average yet. After the time period has ended, the actual category is computed and all bets are totaled up and distributed among all people who have bet the winning category.

In some occasions, there may not anyone who has bet in the winning category. In these cases, the funds from this betting round roll over to the next date. Funds from the pilot round will not roll over to actual rounds, provided this works well enough to provide actual rounds.



Clarifications
1. Sub-satoshi amounts will be rounded to the nearest satoshi.
2. A half-satoshi rounds to the nearest even amount.
3. Winnings will be sent back to one of the inputs. Do not send funds from addresses you do not control.
4. Tainted funds are not given special treatment.
5. If funds (provided that it is more than 0.0005 BTC) are sent to an address after the deadline, but at most two days after, they will be returned minus the transaction fee if applicable. If the transaction fee is zero, they will be returned in full.
6. If less than 0.0005 BTC is sent after the deadline, it will not be returned.
7. If funds are sent to an address more than two days after, they may be returned depending on the mood I am in. Do not expect them to be returned; this is not a money-laundering service.
8. If you win, the winnings you receive are given by (rounded to the nearest satoshi):
Code:
Pool * BetSize / TotalWinningBetSize
9. The Pool is given by:
Code:
TotalBetSize + RolledOverPool
10. A BetSize is given by (provided the amount sent is over 0.0005 BTC):
Code:
AmountSent - 0.0005 BTC



Pilot Round
This round covers this week2. Please check a block-exploring tool for updated bet amounts. As this is a pilot round, instead post the amount of BTC bet.

2012-07-28 to 2012-07-29
Deadline: 00:00:00 UTC 2012-07-29
Code:
RALLY:             -pilot round-
SIDEWAYS MOVEMENT: -pilot round-
CRASH:             -pilot round-

2012-07-29 to 2012-07-30
Deadline: 00:00:00 UTC 2012-07-30
Code:
RALLY:             -pilot round-
SIDEWAYS MOVEMENT: -pilot round-
CRASH:             -pilot round-

2012-07-30 to 2012-07-31
Deadline: 00:00:00 UTC 2012-07-31
Code:
RALLY:             -pilot round-
SIDEWAYS MOVEMENT: -pilot round-
CRASH:             -pilot round-

1: Because this is a pilot round, no actual addresses exist.
2: This round only covers three days because it is a pilot round.

A well regulated market with the government looking over our shoulder to keep everybody in line is the only way to solve this scamming issue.

LOL 

 Roll Eyes

Don't bother with this one. Comes to a forum about a decentralized, pseudonymous currency and suggests that the government taking full control of the block chain and issuing addresses to it's subjects as the best use case scenario.

I'm sorry, since when has the government been a bad thing to the majority of Bitcoin users? Bitcoin is not exempt from government regulation.
2106  Other / Beginners & Help / Re: Membergroups; or: Why do some users get colored coins under their names? on: July 27, 2012, 04:15:26 PM
Nice post.

Could you add information about how the coins turn into other symbols in non-default themes? All standard (non-donator, non-staff) coin symbols turn into stars in the Core theme I am using.
Only the main default theme is supported, the others do not get regular maintenance and may be slightly broken.
I realize that, but there are many people who use other themes. This information might be useful.
2107  Other / Beginners & Help / Re: How did you get your first bitcoin? on: July 27, 2012, 04:13:31 PM
I scammed some sucker by reversing a PayPal transaction after they sent me the coins.
If you are serious, this warrants a scammer tag. Prevention is the key to a solution.
2108  Bitcoin / Bitcoin Discussion / Re: Statement about the suspect of recent Bitcoinica hack on: July 27, 2012, 01:14:04 AM
As pointed out that the owner of ICBC account is "LIU HAIPENG", so how about this clue? Did anyone get something from this guy except that the account is from Mudanjiang ? Did the owner "LIU HAIPENG" and ICBC know the statements in this forum?
Maybe the Chinese government is behind all this.
This is absolutely ridiculous. If no clear suspect is present, blaming "Liu Haipeng" or "the Chinese government" is not a method to find a clear suspect. What happened to logically waiting for the evidence from Mt. Gox's police report?
2109  Bitcoin / Bitcoin Discussion / Re: Statement about the suspect of recent Bitcoinica hack on: July 27, 2012, 12:50:50 AM
Right, "many" people. Yep, solid evidence here.

http://q.3hk.cn/u/zhoutong.html

I fail to see why you're arguing against something that only takes seconds to verify.

http://blockchain.info/address/12c6DSiU4Rq3P4ZxziKxzrL5LmMBrzjrJX

Do you still dispute that that address belongs to satoshi?

Please, respect my right to be skeptical.
2110  Bitcoin / Bitcoin Discussion / Re: Statement about the suspect of recent Bitcoinica hack on: July 27, 2012, 12:38:55 AM
This kind of witch hunt depresses my confidence in the forum. Clearly, people would rather trust some anonymous person who posts "new evidence" without base than rational arguments.

With varying definitions of anonymous and rational, of course:

I am the owner of www.cnbtcnews.com. I introduce bitcoin to chinese people.
The evidence is from one person of my qq group.
zhoutong sell LR, and he buy LR from zhoutong.

How does this person know for sure Zhou Thong was behind U9236056?

He buy LR from zhoutong ,zhoutong show the LR account and the total fund is $23439.57.

How do you know he bought it from "ZT" if it was just over electronic communication?
Many people in China of bitcoin community knows zhoutong's qq account, so that's zhoutong.
Right, "many" people. Yep, solid evidence here.

Quote
Many people in Japan of bitcoin community knows satoshi's satoshidice account, so that's satoshi.

I apologize for my attitude, and apologize in advance if I am wrong (which there is a substantial chance of, I admit). But right now, there is insufficient evidence to convince me that Zhou Tong is guilty.

I've been wrong before, and I won't deny that even I think there is a substantial chance that I will be wrong. But there's no point in accusing people until solid evidence has been posted.

2112  Bitcoin / Bitcoin Discussion / Re: Statement about the suspect of recent Bitcoinica hack on: July 26, 2012, 11:57:20 PM
so in 69 minutes and 32 seconds you called this guy whom you know only little, reached him, explained the situation to him, clarified the hack, convinced him to return the coins, calculated an estimate return and wrote the lengthy statement...

are you kidding me?

You forgot one thing (not sure of its relevance until I see a reply(s)): What was the local time of which both parties were in when this took place? Was contact made my phone? (maybe two things) The millionaire just happened to be available to take your call? (maybe three things) The millionaire really felt threaten by your call? (maybe several more things)

~Bruno~


Zhou made his post saying that he'd identified a suspect and was going to call him at 20:46:19 Australian Eastern Standard Time.  China is behind us timewise, so it would have been late afternoon to early evening there, depending on where in China the call was received.

All of China is in the same timezone.
2113  Bitcoin / Bitcoin Discussion / Re: Statement about the suspect of recent Bitcoinica hack on: July 26, 2012, 11:51:24 PM
That all seems entirely plausible, yes.  There is a reason we replaced this kind of lynch mob justice with a government run conflict resolution system in the courts, they know that people who want to believe someone is guilty will let that color their opinion of the facts in a counter-productive way like what is happening with you right now.

And there is a reason why we find your constant agreements with Zhou and his Tallstory incredibly hilarious.

Oh and isnt it amazing after people commented on Zhou story as complete bullshit he doesnt post any effort to defend himself yet as he did before this amazing story. Yes he thought we were all so gullible that we would hang on every word of his, game over.

See, this is how it is so clear you folks just want to blame Zhou Tong and will use any fact of the matter to condemn him.  When he accomplishes something quickly, tracking down the hacker and talking to him that means he is guilty and is running some massive secret hacking conspiracy.  When he is away for a while, perhaps working further to bring this episode to a conclusion, that too is a sign he is guilty and is running some massive secret hacking conspiracy.  

ZT, you should be spending less time here playing shill and more time getting the money back...
I'll believe Zhou Tong until the side that says it's him actually posts some evidence. Since aurumxchange posted their post, no information has been posted other than "hey look, some of the most reputable people say there is more evidence!".

Bitcoin is not a good digital currency for buying Bitcoin, for obvious reasons.

Maybe. Can you explain your point?

I hope you're not serious.

If you are, please explain to me how you can purchase BTC for BTC, and who will sell you the BTC. Also make sure to include the current price of BTC, in BTC of course.

Don't be so sure, there could be cases where you buy BTC with BTC

Mixing, Laundry. That's exactly what buying BTC with BTC is. And people do that already.

No, it isn't. Neither is collecting coins, expect in rare situations.

If I need 100 BTC, laundering is not going to help me. Unless I happen to have a block in high demand, neither is selling my block. What will help me is some CAD.

BTC is a useless commodity for buying BTC.
2115  Other / Off-topic / Re: Z got GoXed?! how will this effect the price on: July 26, 2012, 11:38:40 PM
I don't believe Z, sorry.
I think he's more trustworthy than the people at aurumxchange, who are known for baselessly attacking competing businesses before. In fact, a substantial portion of aurumxchange's posts seem to involve blaming other individuals or organizations.

If aurumxchange wishes to clear up their reputation in my eyes and allow their word to be trusted as anything but bullshit, they can post some actual evidence of their accusations.

Disclaimer: I am not involved in any competing business, nor have an interest in Bitcoinica or any of Zhou Tong's endeavors. Neither have I endorsed Zhou's statements. I claim no evidence falsifying aurumxchange's statements, however inconsistent and malignantly motivated they may seem. I am posting this merely as an expression of my own opinion.

You don't have the luxury to pick and choose. Bitcoin exists outside of institutional (legal) control and protection. We cannot have our cake and eat it.

BB.

This is extremely naive.


Exactly. You don't have the luxury to pick and choose. By integrating with society, you are part of the legal system whether you like it or not.
2119  Bitcoin / Bitcoin Discussion / Re: Statement about the suspect of recent Bitcoinica hack on: July 26, 2012, 04:30:41 PM
How convenient! And you know what, it is bullshit!
I would love to be proven wrong but fear that I won't be.

USD was taken as well, authorities are well versed in dealing with USD based crimes. Law enforcement has recovered virtual furniture and goods before so I also challenge the claim they would be incapable of dealing with bitcoins.
I see what you mean but do not believe similar cases are relevant to bitcoin, which has not been subject of any significant court proceedings.

Of course it's bullshit.  Most - if not all - of the countries involved have specialised computer and financial crimes units and police regularly call in civilian experts to assist with their investigations (especially universities).  There are plenty of technology experts they can call on for assistance.
Of course they can, however, legally bitcoin will be dismissed as a criminal money-laundering network for which there are no "victims".

The prosecution is not the financial burden of the victims in criminal cases - the only people who would have to worry about legal fees would be the accused.
Only when the "victims" have won the case will the accussed have to pay their fees and damages. That does not account for being able to financially propel a prosecution for the length of any investigations and court proceedings. Go on, ask a lawyer to work on your behalf for free in lieu of payment after success. Indeed, the accumulated cost of bringing this whole saga to court will cost more than what was originally stolen.

In theory a court case may be possible, but by considering just a few practicalities, it seems highly unlikely.


This is only vaguely related but:

At first everyone's like "Yeah, fuck state government and central authority. We don't need them to run our economy! Let the people take their money into their own hands! Bitcoin FTW!" In fact, this forum is full of slogans like that.

But as soon as people lose their precious coins due to their own carelessness and greed to a dubious enterprise in the East they all go running for law, police and central authority to rescue their asses.

And you know what happens when you ask authority for help: they will place their protective palms on your butts and slowly move their middle finger up your cavities.

I'd rather have a glass of champagne with that Chinese millionaire and take a look at his relic collection (and maybe steal one) than listen to a heard of sheep whining and complaining to authority.

Most of y'all early adopters will lose most of their coins anyway and still end up richer than today. Just you wait!

[/yadda yadda]
This man speaks sense.

Tell me, why are the vast majority of Bitcoin users not allowed to enlist government support because a few people don't like it? Nothing exists outside of institutional control and protection, and I can assure you most Bitcoin users are more than happy with that.
