sorry, my mistake. I thought fees were recurring.  Embarrassed

I mean new fees keep being paid on new tx, but for any one tx there is one fee which is chosen and attached by the sender.

It's on my list to show my balances on the home page, but it's non-trivial to implement

Showing your balances is also a good way to attract hackers to try to break in!

You can figure this out with trial and error anyway. It would just be a convenience for regular people. He doesn't need to show his entire assets, only what is currently available.
5103  Bitcoin / Bitcoin Discussion / Incentives (and an idea) on: March 09, 2011, 06:47:36 PM
I'm constantly amazed by how well built Bitcoin is in terms of providing incentive for right behavior by nodes. Eg. you don't build off a bad block not because you are honest but because others won't build off of yours and you will never get your reward paid. Or how new block finders have incentive to share as quickly as possible.

It occurred to me that when two versions of the same block are found near the same time miners are ambivalent about which to work from and arbitrarily choose to continue to work from the first that they received. But the finder of each version has a large desire for his block to be chosen. If he could offer a small extra reward for building off of his block then this would be in his interest.

I think there is a way to do this, I don't know for sure if it works or if it is the best way.

Make a new address.
Pay desired amount to this address, but do not announce the tx, put it only in your version.
Make a payment from this address that has a fee attached.
This fee can only be collected by a miner if they work off of your block because otherwise the address will be empty.

If this works or if someone knows a way that does I think it has some very exciting implications which I will elaborate on.

Suppose you sell some bitcoins on mtgox and when you go to withdraw the proceeds, he says, no I think I'll keep them. Is your only recourse to eat the loss and take your business elsewhere? Can he really run his business "any way he wants"?


But what you fail to realize is that he can only do that to you because as soon as he robes one person...

I trust him not to, but he'd get us all at once, not one at a time.

I really don't care if you trust him or not. If he does something bad he'll do it only once and then the market will come with ways to guarantee it's far less likely or even impossible to happen again.

Sure, I was just pointing out that it would likely be more than one person. I totally get that we will find ways to solve problems that arise.

5106  Bitcoin / Bitcoin Discussion / Re: Possible to "trade" blocks? on: March 09, 2011, 03:58:45 AM
if block trading was possible in the future, there might be people who buy blocks as an "investment", because they pay a "dividend" (transaction fees)

Maybe you are missing the fact that the transaction fees are completely know when the block is solved? There is no recurring fee or anything.

Maybe you are thinking of paying a miner now for, say, the first block they find after block 220k or something? Essentially making a bet on the fee activity in the future? Probably the best way to make this bet would be to buy or contract for mining equipment.
5107  Bitcoin / Bitcoin Discussion / Re: Possible to "trade" blocks? on: March 09, 2011, 02:19:42 AM
Eh, I guess there are two ways you might try to do this. First the impossible way: You take his valid block and replace his address with yours so you can receive the reward instead of him; this fails because changing that will change the hash of the block and it won't be valid anymore. Second he could send you the private key that goes with the public key that is being assigned the reward. You will not be sure that he doesn't retain a copy of the key so you should spend the coins to a new address of your own. But if you are going to do this then you might as well let him get the coins and send them to your new address himself.

Maybe I'm missing your point, but I don't think there's any reason to try any of this.
5108  Bitcoin / Bitcoin Discussion / Re: List of transactions on: March 08, 2011, 06:29:49 PM
Whenever any coins at an address are used they must all be used. Since you want to be able to send any amount this is handled by sending some of the coins to your intended recipient and some back to a new address of your own. This would mean 1 input and two outputs. But sometimes you don't have enough to make the payment with just one of your addresses so you have to combine 2 or more inputs to make the payment. So really any transaction can have any number of inputs and outputs, but usually only 2 outputs. I think making >2 outputs easier is the goal of the recently implemented sendmany function.
5109  Economy / Marketplace / Re: Gold And Silver Maple Leaf Coins To Sell For Bitcoins on: March 08, 2011, 06:13:57 PM
Maybe you could sell "The right to buy a 1oz GAE for bitcoins at the spot price using MtGox weighted daily price on"

I think this would essentially let people bid on the premium. It is not an 'option' because it isn't the right to buy at some in or out of the money point. It's just the right to get it at whatever that days spot is. It would be silly for someone to win, pay the premium, and not buy the whole coin. And if they do, you still get the premium and can sell the coin again.

That might not be the clearest way to explain, and you would want much clarity since it's an odd thing. You'll probably get people thinking they are getting the coin for just the price of the premium, lol.
5110  Bitcoin / Bitcoin Discussion / Re: Thought Experiment: Is Bitcoin a Ponzi scheme? on: March 08, 2011, 05:44:02 PM
It's kind of silly to say that miners who sell bitcoins aren't giving anything back. When they sell coins they are giving the best version of money I've ever heard of and getting crappy old dollars in return.

Is Bitcoin only a ponzi if it fails? Is every currency system a ponzi or become one after it falls?
5111  Bitcoin / Bitcoin Discussion / Re: If Bitcoins catch on, will people get used to having so few? on: March 08, 2011, 12:55:52 AM
People will not get used to having only a few, they will strenuously try to get more inadvertently providing wide and powerful backing for them.
5112  Bitcoin / Bitcoin Discussion / Re: malicious "gifts" on: March 08, 2011, 12:53:50 AM
I was not thinking of someone eating them. I had remembered news articles involving people would would have severe reactions to simply coming in contact with peanut oil. Something that could happen simply opening a box. However when looking for source to back that up I found that such claims are wildly exaggerated. So that concern is a non-issue. Still there is the issue of more minor harassment with little chance of being caught.

Lol. I'm going to make brokenbottleofpeanutoilforbitcoins.com and anonymousbuttplugsforpoliticians.com right now.
5113  Bitcoin / Bitcoin Discussion / Re: Thought Experiment: Is Bitcoin a Ponzi scheme? on: March 07, 2011, 11:25:08 PM

Off peak hours are when free/low fee tx will get in.

No-transaction-fee transactions will only get processed when a miner who accepts NTF transactions finds a block. I suspect that all miners will mine 24/7, so I don't think NTF transactions are any more likely to be processed in the middle of the night than they are during peak business hours.

(Plus 'off peak hours' may not mean anything as I suspect Bitcoin will be used all over the world.)

Some miners will probably be programed to fill blocks with tx in order of fee size, and include free tx only if there is extra room. Maybe the backlog will be hours, days, years, infinity, but if it ever gets cleared it will probably be when fewer new tx with fees are coming as opposed to when the most are coming in.
5114  Bitcoin / Bitcoin Discussion / Re: Thought Experiment: Is Bitcoin a Ponzi scheme? on: March 07, 2011, 11:23:17 PM
Because this would reduce the total hashing power, the point about the defense against attacks: I'm not expert enough, but there should be a way to detect an adversary based on "inconsistent" blocks in the chain? There are probably more ways to automate this.

No, "inconsistent" blocks are rejected by all honest blocks no matter how much power an attacker has. What power allows you to do is right a new consistent chain that doesn't contain a payment that you previously made. People will know afterwards, but presumably the attacker will have already gotten his merchandise or whatever.

@FreeMoney
The main point is that payout is proportional to difficulty, i.e. work done.
So it will rise exponentially as long as Moore's-Law holds, and there should be less (no?) incentive to get in early.

I don't understand. Do you think there is too much or too little incentive to get in early as Bitcoin is now?

Any difficulty rise that happens due to Moore's law won't affect miners generally, the will need to do more hashes/payday, but they will also have the advantage of being able to hash faster.
5115  Bitcoin / Bitcoin Discussion / Re: Thought Experiment: Is Bitcoin a Ponzi scheme? on: March 07, 2011, 11:06:29 PM
→ more blocks are generated during peak hours

Bitcoin with no changes will eventually do this.

→ transactions are cheaper during off hours

Off peak hours are when free/low fee tx will get in.

→ electricity is not wasted on security when not neccessary
If there is some way to tell when it is necessary then I'm all ears.

 → defense is payed for in small bursts of inflation

I think it's pretty smooth, but this will end eventually anyway.

edit: Bitcoin is pretty freaking clever imo

I have several hundred random JPEG images of women from various Internet sources, and of varying quality, as I'm sure many people do. I don't think the majority of them are quite what you're looking for though, as only a small percentage of them could be considered "amateur".

I think he's already seen all the porn on the net and wants more :-)
5117  Economy / Economics / Re: Attempting to understand difficulty on: March 07, 2011, 05:59:43 AM
The block finder provides the timestamp? I remember hearing about some rough restrictions on acceptable times relative to other blocks. Is there enough play to allow exploitation by a miner who preferred difficulty to be a little lower.
5118  Economy / Economics / Re: Will deflationary model be a hindrance to general acceptance of Bitcoin? on: March 07, 2011, 12:32:19 AM

Deflationary bitcoin is predicated on the assumption that bitcoin demand will grow faster than bitcoin supply (currently BTC 7200 per day).

Bitcoin has lots of money supply inflation now, but that will slow and then stop. It could have price inflation if new coins were not met by new users or increased use.
5119  Economy / Economics / Re: Will deflationary model be a hindrance to general acceptance of Bitcoin? on: March 06, 2011, 11:37:03 PM
Deflation fear mongering is beyond retarded. OMG I'm going to be richer tomorrow, nooooo. Economies don't grow because people buy and use shit; economies grow because people make more than they use. Jesus, this would be Econ 001 in a sane world. Guess what, people close to the fucking spigot lie to you.  

How the %$&^ could it be better for people who work for money to have their money lose value instead of gain it?
5120  Bitcoin / Bitcoin Discussion / Re: Targeted advertisement - Who would BitCoins appeal the most to? on: March 06, 2011, 10:47:56 PM
Getting paid to do something you love, build beefy computers, hook them up into lans and pretty much sit on it does sound like a good business however I also wonder if all they do with the bitcoins they made is trade them in for USD dollars then eventually those Bitcoin to currency traders are going to have so much Bitcoins that they'll probably close shop. It will end up being like trading furbies. Eventually nobody cares anymore. So my question is why should I take my hard earned money and exchange it for Bitcoins if all I can do with Bitcoins is exchange them back into dollars or maybe I could get another bitcoin client going and trade my bitcoins back and forth...

What am I going to do with all this damn gold! Pfft, I guess I'll just trade it for dollars, lame.
