you guys can shit on TED all you want

I hope this wasn't because of me.  There is some really interesting stuff that shows up in TED talks, and it can be a great way to get interesting new ideas, like bitcoin, out there and in front of a fairly big audience.

But it is also and at the same time, a support group for narcissists.  That shouldn't surprise anyone, because it is essentially a generational evolution of the other big narcissism support group, TV news.

This is most easily seen by watching a few talks that are outside of your area of interest.  Since you won't be focused on the subject, you'll be able to see the other clues more easily.
2722  Bitcoin / Bitcoin Discussion / Re: Where will stop, the size of the database bitcoin. 1GB+ on: September 02, 2011, 03:45:27 PM
There isn't any real need for a large number of nodes that keep a full copy of the blockchain.  There probably isn't any real need for any node to keep a full copy of the blockchain unpruned at all.  Pruning of transaction data that 1) is older than a certain period of time, say three months or15K blocks or so and 2) has been referenced (spent) and the referencing transaction has been referenced (i.e. the transaction is at least two transactions long spent) will eventually result in a fairly stable blockchain size that mostly varies by transaction volumes over those three months.  Some clients won't keep spent transactions unpruned at all, and will thus have a much smaller data footprint, growing only by the size of the block headers; which amounts to about 4 megs per year.

That said, some nodes will keep full copies of the blockchain, if only for archival reasons.  It's not neccessary that these nodes have high bandwidth or super powerful machines either.  I have a VPS that can keep up with the blockchain just fine, that I direct my other client(s) to bootstrap and update from, since I don't keep clients running either on my home machine nor my android phone and I don't want either to announce to the network or to the bootstrapping IRC channel that they exist.

The hash of a pruned block will not match the hash in the header, and thus a pruned block cannot be verified.  Checkpoints will help this a bit, in that you'll have a verification chain (by a signature on the source code or binary) that says that someone "trustworthy" claims to have verified up to a certain point.  But you won't be able to prove it unless you have, or can get, the full chain, but you don't need to have all of it at once.

Can I ask why you don't want to use your own code to manage balances and transactions?  It seems to me that you need to do those things anyway, at least in most scenarios that I'm familiar with.
2724  Bitcoin / Bitcoin Discussion / Re: bitcoin vs solidcoin on: September 02, 2011, 03:27:11 PM
hmm could you not quickly mine a lot of coins and spend them repeatedly to buy bitcoins? what about creating the longest chain and not allowing any transactions? what about restarting the whole chain from the beginning or from a while ago and making it longer than the current one thus deleting all transactions that happened? ok, I have to read up on possible attacks  Roll Eyes

Ever watch the debug.log while a new chain was starting?  The churn is amazing.  Just having a pool up with long polling means that you will be mining as if you had many times your actual hashing power, because you'll be the only entity not wasting 99.9% of your work.

During the early hours, I'd bet that a LP-enabled pool with like 10% of the hashing power and a client hacked to ignore incoming blocks could completely dominate 100% of the chain for at least a few difficulty cycles.
2725  Bitcoin / Bitcoin Discussion / Re: TED discussion - Bitcoin - Commerce without Borders on: September 02, 2011, 02:04:31 PM
In my opinion, the most important contribution (by far) of bitcoin is that it enables true 2 party transactions to occur over the internet.  That has profound social implications and might be something that the TED crowd would would be interested in hearing about.  The fact that bitcoin isn't issued by a central authority is of secondary importance.

This is TED.  The problem isn't "promotion", it is that you are trying to promote the wrong thing.

Try rewriting it in the language of self-promotion.  You explain the social implications, but the subtext needs to be that you are totally awesome because you understand this cool new thing, and by extension the audience will be much cooler than all of the dumb proles out there because now they know it too.

And before anyone flames me, go watch a few talks.

The non-aggression principle can be applied or ignored by both atheists and religious people. There is no monopoly on rationality and life is simply to complex to claim that you are rational on all fronts. Remember one of the least rational and most destructive systems ever was sold as "rational" and run by atheists, unless I've just misread this whole thing about the soviets and they were all closet Catholics.

Currently the truest and most consistent libertarian with any political power is a Christian named Ron Paul.

The problem that I see with most secularists is that they don't see that secularism is just as much a religion as any other.

And I find individual fundamentalist secularists to be at least as annoying as fundamentalist christians or muslims or jews, maybe a bit more.  In aggregate though, they are much worse because it is apparently socially acceptable to loudly display secularism as a status marker in bars.

Let me get this straight. So everything is a religion? There is no atheism? Gimme a break!

You've never met anyone that had serious faith in their atheism?
2728  Economy / Economics / Re: Question About Supply on: September 01, 2011, 03:09:55 AM
From what I understand, the supply of BTC increases at the same rate no matter how many people are mining. Isn't this unrealistic, since if it were like mining in real life, supply would increase less with fewer miners and more with more miners?

Mining is the least important part of mining.

Pretend that gold was the only money around, and that there was exactly one once of gold in the world, and that it had already been mined.  No one would be employed mining gold, but many people would be employed assaying tiny specs of it.

Bitcoin mining has a lot more to do with assaying than it does with mining.  We are verifying that no fake gold is coming to the market.

Just that in the bitcoin world, we only have access to a third of that ounce of gold, and there is a strange quirk of the assaying process that makes more gold show up whenever we successfully complete a test, and that the amount of new gold will gradually diminish at a fairly regular rate until the whole ounce is here.

Oh, and real gold can only be divided to a finite degree before it stops being divisible (or stops being gold!).  Currently we don't bother dividing bitcoins beyond a certain size because there is no point to values that small.  But there is no limit to how finely we can divide bitcoins if we ever need to.  A few more bits and we could assign a part to each and every atom in the solar system.  A few bits beyond that and we could give a part to every quark, electron and photon in the universe.
2729  Economy / Speculation / Re: Bitcoin growth - The Long View on: September 01, 2011, 02:54:35 AM
Exactly.  If people are offered something they have no interest in buying, then they aren't going to buy it, regardless if it's the greatest payment method known to humankind.

Enter Bitcoins.

Excellent observation, Synoptic. Now for extra credit...

! interested(x) --> ! Buying(x)
Buying(x) --> Interested(x)
x = bitcoin
! Buying( bitcoin ) --> ?

Ooh!  I know this one!

! Buying( bitcoin ) --> ( Interested( bitcoin) | ! Interested( bitcoin ) )

And if I could only remember where I last saw my discrete math textbook, I could prove it!
2730  Economy / Speculation / Re: Gox is Goxxin! on: September 01, 2011, 02:50:48 AM
I'm always curious when I read these threads.  Exactly how would bots be prevented?

Does the existence of things like curl, or various schemes for breaking CAPTCHAs change your plan at all?

Are you at all bothered that banning bots (and enforcing the ban!) would mostly hurt legitimate vendors that need to hedge their exposure so they can continue to operate?  Or that the big traders will have the resources to most easily bypass whatever scheme you suggest?
2731  Bitcoin / Bitcoin Discussion / Re: Two researchers from University College Dublin investigate the the 500K theft. on: September 01, 2011, 02:33:41 AM
1) Active attacks on anonymity, on the bitcion network.
There's some people using mixers.  But how do you know your coins are really mixed?
Lets say you trust the mixer.

But what if your coin is mixed with a bunch of other coins, all of which belong to an adversary?
If I was interested in actively attacking Bitcoin, I'd be flooding mixers all the time.

I could make it appear to another user that their coins were mixed, when in actual fact, I controlled all of the coins they were mixed with, and could tell for sure what the incoming and outgoing coins were.
Obviously, as the mixer takes a fee, there's a cost, in Bitcoins, to doing this.

But, while I've seen a lot of talk on mixers out there, I haven't seen this sort of threat mentioned (maybe I'm missing something - this is something to consider, not something I've thought about in depth.

If the mixer is designed well, and if the operator of the mixer is trustworthy, then it doesn't matter much what coins you get back, the same ones, or different ones.  The crypto community probably already has a pretty good idea of which properties the mixer needs to have.  I bet that the cypherpunks list probably even had detailed discussions on how to create a distributed system that didn't rely on the trustworthiness of any particular subset of mixer operators.  We just don't know which thread to look in, because they didn't know they were talking about bitcoin at the time, they thought they were talking about an email mixer, or how to protect an onion router from traffic analysis attacks, or something.

I liked the paper, by the way.

I always consider claims of anonymity to be false until shown true.  And even then I'm still cautious.  I remember well that the first few things I had read about bitcoin made claims about anonymity that (surprise!) later turned out to be less than true.  I tend to blame journalists for bad journalism, but in this case I might be willing to cut them some slack.  Bitcoin is hard.

I would say that by now, most people in the community (at least in the threads that I read) have a fairly good idea of the level of privacy actually available for various types of transactions.  Of course, an attacker with the ability to aggregate data from a lot of places can overcome casual efforts at partitioning and end up knowing a hell of a lot.

Some day, there will be a simple web based tool, like blockexplorer, but much more sinister.  You'll be able to punch in an address, and it will track things forwards, backwards and sideways.  It will magically divine every address in your wallet that you have ever received money from, and if you've ever used or sent to a static address, it will be able to tell you a lot about yourself and what you like to spend your coins on.

The good news is that places that generate new addresses for every transaction will make it much less accurate.  And hopefully a network of decent mixmasters will provide hard edges, or at least plausible ones.

Most people don't know how serious white collar investigations work, so they don't realize just how much effort it will be for someone to keep those edges solid.  Real investigations cast a wide net.  They look at someone, then they look at everyone around that person, and then everyone around all of them, and so forth.  They look for coincidences first, and then patterns, and then evidence.  Honestly, if you let it get to the evidence stage, you've already lost.

I see a lot of people on these forums that say things like "well, they can't prove <this step>".  It doesn't matter.  They don't need to prove that step, they just need to see the pattern, and then find some other step that they can prove.  Where there is a pattern, there will also be evidence of something, something that they can use.  They are professionals, and you are an amateur.  They are much better at finding evidence than you are at hiding it.

For anyone seriously considering hiding some crime behind bitcoins, I offer this advice.  Don't.  And if you ignore that part, try to avoid coincidences, and make damn sure you don't leave patterns.  Be many different people, with different personalities, different habits, different patterns.  And if you must transfer money from a wallet that can be linked to you (and this is any wallet that you haven't taken great pains to keep apart from yourself), to an illicit wallet, make sure it is for something legitimate, with paperwork, and hopefully eyewitnesses that really think that they saw you buy or sell something.  Don't try to launder funds more than once, unless you have a legitimate, documented, witnessed sequence of transactions that will look completely normal and mundane.  And finally, make damn sure that you lose a hell of a lot of money along the way.  If 50,000 bitcoins leaves one side, 50,000 bitcoins had better not pop up on the other side, not even months or years apart and from totally different directions.

Sorry.  This is long, rambling, and I think I veered offtopic a bit.  Fun though.

I'm no shady strategist so I bet I'm missing a lot simpler ideas and also, ones proposed above do not actually work out to a profit mathematically.

I do wonder why you are calling out a hero member as a shady strategist, but I haven't read all of kjj's posts, so he could be I guess.

I didn't read this as him calling me shady.  I just saw him saying that he wasn't shady, not in contrast to anyone, but in general.

My posting history is a mixed bag.  In one post, I'll be a complete jackass.  In the next, I'll be patient and helpful.  In the next, I'll be both.  And so on.

In the spirit of disclosure, I'll say that my join date on these forums was essentially the day that I learned more about bitcoin than just the name.  In that time, I've mined about 100 bitcoins, and I've spent about 25 of them on various things like shirts, tokens, computer parts and dollars.  I wrote and operate my own bot, which is not at all like a traditional trading bot.  It has been far more useful than profitable.  Since it started, it has made a profit of about a half bitcoin (minus the value of my time, which is apparently zero), and hasn't made a trade in several weeks.

My question to Desolator was, and remains, "What about these trades makes them unfair?".

The larger point that was I was getting at was this:  On the exchanges, each party gets to set the exact conditions for the trade.  You tell mtgox, or tradehill, or whatever, that you want to buy or sell, how many bitcoins, and the worst price you'll accept.  You never pay more than you specified when you buy, and you never get less than you asked for when you sell.

In what possible way could anyone consider a trade which happens under the exact conditions that they specify to be unfair?
2733  Economy / Speculation / Re: Here we go again, another major price drop for bitcoins on: August 31, 2011, 11:02:42 PM
We did the dart test over a year in college economics class.  It has been done before in 1988 till 2001 I think it was.  Here is a link, it was monkeys throwing darts to pick the stocks vs the pros

http://www.automaticfinances.com/monkey-stock-picking/

THe numbers were effected by pros choosing riskier stocks, and some inflated winning in the very begining from the announcements. But in the end it came down to this.



Pros picked riskier stocks: Case Western Reserve University professor Bing Liang says that, adjusted for risk, the pros' would have lost 3.8% on the market over the six-month period.
The Dartboard stocks continued to do well:

 After the contest ended, the dart stocks continued to perform, while the pros' picks fell from their initial highs after publication.

So it basically showed, and there were more tests done very similar to this, that there is a small very small minority of investors that do really well based on facts, knowledge etc.  When in reality, it has most to do with luck, or insider trading, like knowing the bitcoins were going to jump to 30 bux a coin before they did, now that would have been nice lol

No discussion of stock picking is complete without The Tao of Alpha.

Tiny cosmetic "feature" request:
If the user starts the app once a day, the syncing progress bar hoovers around 99% without any movement for a few minutes.
I think it would be better if the progress bar would always start at 0% and can therefor show some movement.
What I mean: the old (already downloaded) block count is represented by 0% and the up-to-date block count is 100%.
Now the casual user can see some progress bar movement, and all is well Wink

The problem with this is that the chain doesn't have an end.  It doesn't even have a current endpoint.  All it has is the dividing line between blocks that your node knows about, and blocks that it doesn't know about yet.  It seems like a trivial thing, but the misunderstanding can have serious consequences.

But yeah, the progress bar could be better.  But you can't make it too good, or it will confuse users.  There is even a trope about it.

Using the last known block height like you suggest seems like a good way to do it.
2736  Economy / Economics / Re: A Resource Based Economy on: August 31, 2011, 02:52:44 PM
The history of money is more complex than that. Not that I agree with all the opinions expressed in the following links, but just take a look:
http://www.nakedcapitalism.com/2011/08/what-is-debt-%E2%80%93-an-interview-with-economic-anthropologist-david-graeber.html
http://www.webisteme.com/blog/?p=384

The first article is quite good.  But money only had to be invented once, more or less.  That it started out as a way to standardize debt isn't really important, because eventually the gold -> paper -> bloodshed cycle took root.  The obvious examples are Rome, France (revolution era), and everyone on the planet today.

The second link less so.  I don't think that the author realizes that the system he is describing is almost identical to the system we have now.  The main differences that I see are that he proposes rolling back the whole specialization/division-of-labor thing that we've been working on for the last couple thousand years, at least in regards to creditworthiness assessment, and socializing the costs of bad lending decisions.  And shit, we've pretty much done the second part already.

In the baker example, I'm saying that a baker might be better off by letting the bread rot rather than lending it out, whether for interest or not.  Giving it away wasn't even a consideration.

Then we disagree here. If we assume there's no risk in the loan or the risk is properly factored in, the baker is better if he loan his bread instead of letting it perish.

Possibly.  I don't think that the situation could be fully analyzed in advance, it would really depend on a lot of details specific to the time and place.

That last two bits tie together very nicely.  I was going to say that a rational lender and a rational borrower would strike the exact same deal under demurrage as they do under inflation, or even deflation.  Then I went off and read the link that you posted again, and I got the same feeling that I had at the end of my previous post:  Once again, you are so close that you could reach out and touch it, but you still don't see it.

Then you haven't understood my example. Demurrage allows capital yields to drop below the basic interest that you can extract from the liquidity itself. On the other hand, inflation increases the opportunities of making money out of trade and speculation.

Except that inflation and demurrage are different words for the exact same thing.  They both mean "money is worth less tomorrow than today".  The mechanism isn't important, unless you are talking about specific implementations rather than general concepts.  And if you are talking about specific implementations, I will agree that the one we use today sucks, but the sucking is political, and merely changing the name won't prevent the exact same thing from happening after you change the name.

Also, the thing that you call the basic interest rate is the lowest interest rate that people are willing to pay to finance good productive ventures.  Capital yields can't fall below that level by definition.  Or more accurately, if it does, it is an economic loss compared to what it should have been.

And finally, trade and speculation aren't evil.  They help capital find the right places to be.  They only look evil right now because the men with guns (government) are letting their friends abuse the system to do things that sorta look like trade and speculation, but are actually robbery.

The distortion in the world is clearly not inflation, it is with the specific way that inflation is implemented, first in one place and then flowing out to the rest of the world unevenly.

This is key. Unlike inflation, demurrage affects every money holder equally and instantly.

I don't believe this for a second.  As long as the broken system is allowed to exist, it will seek (and find!) ways around obstacles.  The only way it could work is by taking power away from those that abuse it.  And if you've cured the disease (abuse), why replace one of the symptoms of abuse (inflation) with a synonym (demurrage)?

You clearly dislike inflation, but you are putting all of your efforts into replacing it with inflation-by-another-name (aka, demurrage) when you should instead be thinking about how to change the political structure that hands out favor in one place at the expense of the rest of the world.

My lack of faith in politics is what made me reject Gesell's freigeld for some time. While reading anarcho-capitalist literature, I realized that the money issuance must be taken away from the hands of the government.
I first focused in mutual credit systems like LETS as the only private way to make money without interest. The interest disappear here by removing its scarcity instead of its perfect durability.
Then I discovered bitcoin. And short after that, Ripple, the ultimate mutual credit tool. Unlike LETS, ripple is scalable.
With the block chain, the possibility of scarce money with demurrage out of the hands of the state becomes possible. That's why I advocate freicoin.
Although gold is better than the current system, Gesell convinced me that gold-money is flawed. This is the central point of our disagreement. 
I wrote a little story to show my point against capital-money.

Sure gold money is flawed.  It is just much less flawed than anything else I've ever seen proposed.  Humanity always returns to gold after a bloody revolution because it can't be abused, which is important when the revolution was against those that had been abused the previous paper issue.

You're overstating the importance of bots.  The only inherently bad or unfair part is when they outbid you purely based on speed and get a deal you wanted.  Otherwise bots do precisely what a human tells them to so they can program it to trade fairly or like a jerk.  A human can manually set up unfair trades and scams and that sort of thing, just not as quickly.  So really the bot isn't that important.

Tell me more about these unfair trades.  Start with exactly what about a trade makes it unfair.

Reply to jtimon, not quoting for obvious reasons.

One thing that I don't like about that equation is that it is too simple.  If we ignore other currencies, the left side is fine.  But the right side is nonsense, it should really be:  (P1*Q1+P2*Q2+...+PN*QN)  You can create the quantity P*Q which has the same value, but you are making a huge mistake if you then think of P or Q as having independent meaning outside the product.

I don't use time-preference as defined in a textbook, I just mean "preference for one time over another".  If you are quoting a formal definition widely understood by economists, then the misunderstanding is my fault for not brushing up on the lingo.  Also, if that is the case, economists are even nuttier than I thought.

I gather now the cause of my misunderstanding on the island story.  You did say "money with demurrage", and I totally missed the "with demurrage" part.  The idea of money with rot built in isn't natural to me.  The history of money is a cycle where humanity tries to make money as nearly indestructible as possible, then politicians invent inflation which first rots money, then replaces it with junk, then rots the junk.  Then there is a great unhappiness, and the survivors start the cycle over.

In the baker example, I'm saying that a baker might be better off by letting the bread rot rather than lending it out, whether for interest or not.  Giving it away wasn't even a consideration.

That last two bits tie together very nicely.  I was going to say that a rational lender and a rational borrower would strike the exact same deal under demurrage as they do under inflation, or even deflation.  Then I went off and read the link that you posted again, and I got the same feeling that I had at the end of my previous post:  Once again, you are so close that you could reach out and touch it, but you still don't see it.

Inflation and deflation are neutral concepts.  Neither one has any meaning at all.  If someone added a zero to all physical currency, multiplied all bank accounts by 10, and multiplied all prices by 10, we would hardly notice.  The same would work if they divided everything by 10.  The same works if it happens every night, or every hour, or continuously.

The distortion in the world is clearly not inflation, it is with the specific way that inflation is implemented, first in one place and then flowing out to the rest of the world unevenly.

You clearly dislike inflation, but you are putting all of your efforts into replacing it with inflation-by-another-name (aka, demurrage) when you should instead be thinking about how to change the political structure that hands out favor in one place at the expense of the rest of the world.
