Maybe a service like SatoshiDICE would need a loan. They've been thousands of coins in the red before. A loan would enable them to raise their max bets and absorb temporary losses.

I sent BTC to SR. One hop to an address provably controlled (via input-combining) by 1Dky. End of story.

I too can provide proof of a 1 hop  SR Deposit Address -> 1DkyB

So, where is the evidence to back up your claims?

It seems my main objection really is the oracle. It just seems to manipulable to me in bitcoin's case way too volatile.

Would some kind of smothing be acceptable for an oracle? I expect gamblers will want the most volatile oracle to be used, but for your serious purpose would a smoother one work? It kind of seems like really a call option would be best for your purpose?

I was thinking back to this thread the other day, and I came up with the solution for the oracle problem. When one party wants to exercise the CFD (or when the CFD expires), both parties try to agree on the price. If they can't, the parties must accept trades up to the value of the CFD for their quoted price (adjusted by some reasonable fraction for fees).

Consider this scenario:
1. Bob and Alice create a CFD for 1 Bitcoin, beginning at $5. Bob takes the short, Alice takes the long.
2. BTC-e trades at $6; MtGox trades at $7.
3. Alice wants to use the MtGox price (obviously). Bob doesn't have access to MtGox.
4. Bob buys 1 Bitcoin at $6 from BTC-e, and sells it for $7 (minus some reasonable percentage agreed upon in step 1) to Alice.
5. Alice accepts payment of $2 and sells Bob's coin at MtGox.

Because Bob profited $1 (minus some reasonable fee) from his arbitrage sale, his payment of $2 is really only a loss of $1. From his net loss, it's like the contract was concluded using BTC-e as the oracle.

Because Alice sold Bob's coin, her profit is still $2. From her net profit, it's like the contract was concluded using MtGox as the oracle.

Does this mean that a large miner or a pool op could timestamp blocks either at the minimum or maximum variance allowed to manipulate the difficulty?

1128  Bitcoin / Development & Technical Discussion / How do bitcoin clients agree on what time it is? on: September 16, 2012, 04:08:52 AM
In order for the difficulty to be changed every 2016 blocks, the clients need to know how long it has been since the last retarget. Clocks aren't perfect, though, and there could be malicious clients. How do nodes agree?

Escrow is a great one:
Alice wants to buy a burger (shipped by priority mail Tongue) from Bob, but they don't trust each other, and neither one wants to send first. They both trust Eugene, though. Alice creates a 1-of-2 transaction which can pay to Bob once signed by either Alice or Eugene. The three scenarios:
1. Alice creates the transaction; Bob sends burger. Alice signs the transaction and Bob gets his money.
2. Alice creates the transaction; Bob doesn't send the burger. Eugene sees that Bob is a scammer and doesn't sign the transaction; no money changes hands.
3. Alice creates the transaction; Bob sends the burger. Alice refuses to pay. Once Eugene is satisfied with Bob's proof that he sent the burger, Eugene signs the transaction. Bob gets paid.

It's possible to do this with a 2-of-2 transaction between buyer and seller.  Then both parties have to find an agreeable resolution before anyone gets the money.  Thus, neither party has any incentive to try scamming the other.  However, there's a risk that the coins are locked forever if there is no resolution, so I had started a thread to discuss how it might be done without a third-party.  It's complicated, but it works if you include "risk deposits."  I think most of the complexity can be hidden under-the-hood, though. 

In most cases, you should just use a third-party.  It's very cheap for third-parties to operate because they never really "handle" the money themselves.  But one of the beauties of Bitcoin is that you can have the bitcoin network itself act as your "trusted third-party" in cases where privacy is critical, or the two parties can't agree on a trustworthy third-party.
There is the oft-quoted idea in cryptography that "anything which can be done with a trusted third party can be done without one." We're getting there Smiley

So I've decompiled it, and this is what the source looks like:


1. Build the GUI
2. Output a random string of characters for the address
3. Output 0 for the balance
4. Repeat

Why even bother piuk Wink
1131  Bitcoin / Bitcoin Discussion / Re: Using percentage of bitcoins instead of number of bitcoins on: September 16, 2012, 03:10:38 AM
It is certainly implementable on the client-side. At the protocol level, there are only satoshis. So any client can take the number of satoshis received in a transaction and display it divided by 21,000,000,000,000 (and tack a percent sign on it).

I actually got a payment today that was a straight shot (after a couple hundred hops) back to this address from the 150k withdrawal on August 31st.
A payment from where? Gox? SR?
Not sure, I'm waiting on a response from the sender.

Keep us posted. I'm very interested in learning more about this address.

Why is it you guys are out of funds SO often? Your service would be quite a lot more useful if payouts were more readily available.

I think our prices are too good.  We should probably raise our fees so there are less sales and thus more funds are available. Wink





Even with your line of credit, you still seem to exhaust funds every day Smiley
Maybe low funds should reduce max payout and increase fees Tongue

friedcat, how does one go about selling the bonds back to you at 0.5?

(Yes, I only ask because there's a couple hundred selling under 0.5)

Also, we need to evaluate this statement:
You say these 1% and 1.25% deposits are insured. Who is insuring them? Do you have a link to where this is explained somewhere? Thanks.

These deposits are guaranteed by me.  Which means no one will lose any money if I make any bad investments.
Again, this brings up the issue of time. However, he was never specific about what he meant by "me". You could argue that he guaranteed the program with his personal assets. Should hashking be required to liquidate all assets that can be forcefully liquidated by law?

Or I was guaranteed by Pirate to return my funds back to me.
I believe pirate falls under "bad investments," as quoted above Roll Eyes

Is it really worth it to buy all 8 slots? (I thought only 8/10 were available)

And no, the little guy does not have a right to the ad slots, if that means that the little guy gets them for less than the fair price. Not unless the ad slots are a charity donated by theymos to the community.
