421  Bitcoin / Bitcoin Discussion / Re: I just have the best idea to help people and make BTC even bigger on: May 07, 2013, 07:01:10 AM
That's exactly what Bitcoin100 does.

ok, I get you there you suggest that we can just donate to bitcoin100 ? and this will do it, you are even trolling or missing my point here, i did choose UNICEF for a reason, there you go guess why.

as long you are still thinking inside the box we are not going anywhere, so bitcoin inside bitcoin community wont help that much, maybe you are helping people but you are not doing much for bitcoin

At least look at this list of charities they have already contacted so you don't duplicate effort. https://bitcointalk.org/index.php?topic=55398.msg659165#msg659165

Good Luck!

We need to duplicate the effort! If you think Bitcoin is a viable technology, and if there is a place you'd like to see accept them - please do contact them and suggest they do so.  Don't sound scammy, don't insist - simply make a suggestion.

As for pooling funds together for large donations, bitcoin100 works just fine.

For the time being, since I don't (yet) have a solution for Niko's hack, I appreciate that he's not making it public here. I'm no believer in security through obscurity, but at the same time I figure there's no especially good reason to post instructions for circumventing the tamper-evidence so long as I publicly declare: YES there are definitely ways to reveal the private key without anyone knowing it, and you don't need superconducting quantum NASA laserbeam technology or anything like that. Smiley

1. These wallets aren't designed to be kept in your open space office desk drawer. You should keep it secure and unavailable for others' physical access.
2. More probable attack vector of someone who accessed that wallet physically is to rip it open and withdraw coins. All users should be aware that if someone can access the wallet, they're screwed.

Considering this, I think it's safe to assume that everybody sane will keep their paper wallet secured. And considering this, I think it's better to openly describe the hack, because crowdsourced solution might come much faster.
Good points, Terk. Furthermore, the slight-of-hand attack you described in yor next post is great. BIP38 addresses these kinds of problems, and canton is working on implementing it.

Ok,

I have bitcoin-qt and when I click receive coins I see an address, is that my public key or private key, if it isn't my private key then were can I see that. Also I have an account on mt. gox and I have a different key there, so should I be using the bitcoin-qt address or the mt.gox one?
Welcome to Bitcoinland! Before you start moving money around, I highly recommend spending a day or two reading about the basics of how Bitcoin operates. This will make us all happier.
You can start on the Bitcoin Wiki, stickies in this board, or redd.it/18kt6y

Here is the broad picture:
Private key is a private, random string.
From Priv Key, public key is derived using a one-way function. Practically impossible to do the reverse if you know a public key.
From public key, the address is derived using a different kind of one-way function. Again, impossible to reverse.

You can generate as many key pairs and addresses as you wish. In fact you should have a new one for each transaction. Most wallet programs and online services do this for you.

Happy reading, and come back here soon!

You do realize Bitcoin network is not compatible with space travel due to lag, right? You'd never be able to propagate blocks fast enough, and there would be local forks budding everywhere.
425  Economy / Speculation / Re: Is the MTGox - Coinlab deal in trouble? on: May 03, 2013, 07:08:17 PM
I hope they hired that PR person, he/she could be needed just about right now!  Shocked

If we see mtgox closed price will be single digits.

Why?
The color of his "ignore" button explains why.
426  Economy / Service Discussion / Re: Official Gox / CoinLab Integration and Transition FAQ on: May 03, 2013, 07:05:16 PM
Coinlab don't need 75 mils, they probably can get the same amount by unloading all their coins before filing the lawsuit, and take them back before withdrawing it.  Cool

so No brainer lawsuit, sell coins fud market buy back = Win....

the law suit you had to have
Except- market is not falling for it by any significant measure.
427  Economy / Speculation / Re: CoinLab News = Price collapse on: May 03, 2013, 07:10:41 AM
In case anyone has missed it: this thread was referring to now old news. The latest news imply the opposite: coinlab has filed a lawsuit against Gox.

Am I to take it that the OP prediction is now to be reversed? Cheesy

Necro thread bump. tl:dr, what does all of this mean?
It means eventually somebody was bound to confirm the value of OP by asking the question you asked.

The price influences google trends, not the other way around.
This is correct.
430  Economy / Economics / Re: Bitcoin Hedge Funds Operating Classic Pump and Dump on: May 02, 2013, 09:03:05 PM
Dear minions, I just you must be wondering about the recent dump of the BTC price. Well we've been doing some
analysis overhere on our Cray and it looks like someone big (hedge funds) is operating a pump and dump scheme.
Here's how it works.

1) Fund buys BTC heavily over a period of days/weeks
2) The masses get bullish and start buying
3) Funds stops buying
4) Masses in bull fever continue buying pushing prices to new highs
5) Fund starts selling to masses at new high making profit
6) Masses run out of cash/bull prices start to fall.
7) Fund continues selling pushing prices lower
Cool Masses get bearish and start selling
9) Fund stops selling
10) Masses in bear fever continue selling pushing prices to new lows
11) Fund starts buying from masses at new low making profit
12) return to 1

The free market is a pig sometimes
You forgot 1b, 2b, 3b: spend a little bit to create positive PR, with "news" articles, analyses, empty promises in press releases, etc.
No one should get me wrong - I am an optimist. Bitcoin is a great technology with immense potential. The potential, however, has not been realized. We need more useful tech built on top of it, and less speculation.
431  Economy / Economics / Re: One day, there won't be any bitcoins anywhere on: May 02, 2013, 05:16:58 PM
Nobody sees a problem around here? Well alrighty then, gimme some of that kool-aid already, woohoo yeah!
Read the comments, and think. Also, do the math. How many satoshis are there?

Things usually work out much better when you don't try too hard. After officially giving up, and paying up the dues, I could finally have some fun with the sample wallet. I was able to read the key in about two minutes, without any apparent damage.
Canton, I emailed you with the details.
433  Bitcoin / Bitcoin Discussion / Re: Never seen private key trade system/ Virtual Casascius/ self-escrow-coin SEC on: May 01, 2013, 04:23:52 AM

no, not like zero coin...

its more of a virtual Cassius that never has to interact with the blockchain, until opened.

so I send you a private key that I can prove I have never seen and you can verify this, and you can choose to send on or open, then use as normal
Yes. You could prove that it's never been spent, not that it's never been seen. The way to do this is by using a public ledger of digitally signed transactions.

Thinking forward, it may be possible to prove it's never been seen by using quantum cryptography.

A Joule is a Joule, 10 years ago, now, in the future.
No, it is not. You are discussing a value here, and how much I value one Joule of energy changes depending on the efficiency of the available technology, and what situation I am in. So, the value changes. Even the Joule itself may be changing as the universe is expanding. You built your model assuming constants are constant, so no need to get all excited when your model shows that they are constant.

I finally got a couple of hours to play with the early prototype. Here is what I was able to get by simply shining light through the wallet:


Now, as much as I am satisfied that I was able to read most of the letters, the level of satisfaction will not increase significantly if I spend time doing this until I am able to read all of the letters. If it was a 100-coin wallet, maybe.

Furthermore, canton included a sample sticker (that he did not apply to the wallet he sent it with) that would pretty much render my attempts completely futile: the sticker substrate appears to be metallic. No way we'll be able to read through that any more that we can read through Casascius coins.

I give up! Since this private key was inadvertently revealed elsewhere by canton, I will not be sending my dues there; canton, PM me a new address!

This was fun. Again, if you do make your own paper wallets, and you store any significant value in them, do not take tamper-proofness lightly.
437  Bitcoin / Bitcoin Discussion / Re: A bitcoin user group that is open and expresses the will of the community on: April 30, 2013, 12:10:13 AM
Interesting.

The technical issues will keep emerging as Bitcoin grows and evolves, and these issues will be global, nation-blind. The best way to address them is to concentrate resources in one entity, such as Bitcoin Foundation or any similar group. This ensures we don't waste resources by multiplying efforts.

I therefore propose that we keep discussing best ways to organize, but then organize - and incorporate - locally in each region. These groups could then communicate and coordinate as needed. I am currently in Canada, and would most likely join local group with the formalized membership and voting procedures.

Great suggestion on local chapters. I'd like to roll it all up into a global group, but localizing power is always better.

Disagree on not duplicating Foundation. They have vastly different goals and principles from this proposal. While this is not a "bash foundation" proposal, I think it is valuable to look at some of the areas where they are not responsive and fix those as "features" of an alternative organization
For the record, we agree on BF. I just brought them up as an example - granted, not a good one, but the only one. There is definitely plenty of room for people willing to work on addressing issues which are not likely to get attention from the current BF leadership. I also don't see any fundamental reasons for conflict, such as mutually exclusive goals. It's simply a matter of operating in different areas of the Bitcoin ecosystem. Ultimately, everyone involved wants transactions to keep getting verified and secured, and the advantages over other payment systems maintaned and strengthened.

The best way to address them is to concentrate resources in one entity, such as Bitcoin Foundation or any similar group. This ensures we don't waste resources by multiplying efforts.

On the other hand, we have regulatory issues and educational efforts, which are very country-specific due to different legal systems, culture, and political sentiment. It would be silly to attempt to help Bitcoin in these areas with one-size-fits-all solutions from a single, global entity. What is needed are regional groups that coordinate when appropriate. What OP proposes might work best at this level. Based on IPs of nodes, and number of Internet users per country, we can see that highest levels of adoption are seen in Scandinavia, so these countries may be a good testing ground.

I therefore propose that we keep discussing best ways to organize, but then organize - and incorporate - locally in each region. These groups could then communicate and coordinate as needed. I am currently in Canada, and would most likely join local group with the formalized membership and voting procedures.
439  Economy / Speculation / Re: Trading Log on: April 29, 2013, 07:26:26 PM
I suggest you delay the story, so your current positions are not exposed. Only when your order is executed, you come and tell us what it was. Same value for the reader, but more fair to everyone.
440  Economy / Economics / Re: Bitcoin the Bubblecoin on: April 29, 2013, 05:06:16 PM
Simply expanding the user base will not stop people from pumping and dumping and causing panics. If this were true, then small countries would generally have unstable currencies and large countries would have stable currencies.
This is a valid point. No matter what market size is, there will always be players willing and able to move the market for their own benefit. Even more so when players have essentially free fiat available (banks).
