1083  Bitcoin / Development & Technical Discussion / Re: Forked block chain on: April 17, 2013, 08:22:22 PM
So the question is if there is anything that stops me from doing that since I am branching off the original chain.

When you go off on your own fork you can do whatever you want, including changing the rules for the block reward subsidy.  But again, that only exists on your own fork.  It doesn't matter if you start with your own genesis block or extend off of a bitcoin block.  

You would want to configure a node to relay transactions received on port 8333 so that they also get relayed to your fork.   Some of those transactions will be valid even on your fork but over time more and more transactions that are valid Bitcoin transactions will not confirm on your fork because they include an invalid INPUT as far as your fork is concerned.

The real risk is someone using a copy of their Bitcoin wallet.dat (or the private keys from that wallet.dat) with your fork -- the coins pre-fork are still valid spends on the Bitcoin blockchain as well as on your fork.  So it would be way to easy to lose money by accidentally sending valuable pre-fork coins thinking they are only as valuable as the post-fork coins.

Ya, that would get ugly in a hurry.
1084  Bitcoin / Development & Technical Discussion / Re: Forked block chain on: April 17, 2013, 06:48:13 PM
If I want to grow a new private branch of the blockchain, can I do that and change the rules for block rewards? (with a rewritten client)  If this has been discussed previously I'd be thankful to know.

Are you asking about a hard fork that lets all existing bitcoins be spent on nodes running your rewritten client?  Yes, that's possible.  But blocks mined by your clients would not be accepted by any peer nodes running the Bitcoin-Qt/bitcoind client.

If you wanted to communicate among other peers who want to be on the fork with you then you could change the port number, set up your own dnsseed server and have your own little forked chain running, sure.  Knock yourself out ... if you have 400 Ghash/s (equivalent to nearly 7 Avalon ASICs) you'll get one block mined per day, so nearly a week for a transaction to reach six confirmations.  [Though you could edit this revised client to have it manually reset difficulty as-of a certain block]
1085  Economy / Trading Discussion / Re: Exchange legalities on: April 17, 2013, 06:12:48 PM
I mean, you can't just go open your own currency exchange or forex trading business without some sort of various oversight, licensing, etc? There are all sorts of government regulations and agencies above forex sites like Oanda, for instance. And if bitcoin really is a currency, then how is setting up an exchange any different?

I can just go out an open a store that buys and sells baseball cards without some sort of various oversight and licensing. 

Are bitcoins different from baseball cards?

The are not prepaid access ("stored value"), according to FinCEN.

If you are providing exchange to and from fiat, FinCEN recently released guidance on that.

If you are holding other peoples dollars, there are already regulations that address that as well.

If you are seriously thinking of opening an exchange, there are others that have done it that might be able to provide some advice.    At a minimum, you'll need some capital to cover the legal fees in getting started.
1086  Bitcoin / Bitcoin Discussion / Re: Double Spending and Confirmations Myths on: April 17, 2013, 05:34:11 PM
We would know if someone has more than 50% hashpower
Myth.
An attacker with more than 50% hashpower could be mining his own chain and not announcing it to the network (from the last checkpoint in bitcoind). As his chain will be longer, when he announces it will immediately propagate and override the current chain.

There are two approaches, too.  The March 11th hard fork was essentially a friendly 51% attack.  The "attack" (the switch from the longest chain to the other side of the fork) didn't occur until long after transactions had confirmed post-fork.
 - http://www.bitcoinmoney.com/post/47048259653

Then there is the stealth attack where the miner with 51% has been mining and not releasing blocks as they are mined.

1087  Bitcoin / Development & Technical Discussion / Re: Ask about Bitcoin database on: April 17, 2013, 07:46:24 AM
AFAIK Bitcoin version 0.8.1 uses Berkeley Database. How it uses this DB? Bitcoin not need install database from from oracle.com.I hear that new Bitcoin change to Google database, only Wallet stay with Berkeley DB.

With BitcoinQt/bitcoind v0.8.x, the only BDB database is the wallet.dat.   All prior versions used BDB for the blockchain and other databases as well.  The client has statically linked everything so there is no installation of the database.

Beginning with v0.8.0 was LevelDB for the blockchain and everyrthing else other than wallet.dat

try to determine how they are going to spin it before you agree

Good point.    After that Bloomberg $150,000/day in electricity nonsense (which has been refuted, with the real number being more likely under $50K and dropping quickly thanks to ASIC), portraying bitcoin the way bubbleboy sees it is one likely aim:

in this scenario mining of bitcoins would suck a full 5 to 15% percent of the national electricity production, depending on the capital ratio.

I don't want to split hairs, but if the sheer order of magnitude of these numbers don't concern you, then you might suffer from the modern day version of the gold fever. There's just about no chance in hell a democratic society will allow such a behemoth to live (only to be subjected to the feudal whims of the early adopters that happened to be in the right forum 20 years ago, I might add).

Are you a miner? Do you know anyone with an elaborate mining rig in LA or the Bay Area?"

Well, there was a fair amount of GPU mining in the SoCal area but as "halving day" approached nearly all the ones I'm aware of or have heard from have sold off their hardware.   The cost of electricity in SoCal is high enough that almost nobody was expecting GPUs could still be profitable for mining.  I'm not aware of any miners in the area with an ASIC to show off.  

There also seems to be a reluctance to admit to any significant amount of mining capacity.  I get it ...  nobody advertises how much gold and silver they have nor that they have coffee cans of it buried in the back yard either.  

So, ... there might be the requirement that the reporter not name names and pixelize/alter faces and voices.
1091  Bitcoin / Press / Re: 2013-04-15 Jim Rogers: Gold Drop Partially Caused by Bitcoin Drop on: April 17, 2013, 06:07:41 AM
That is crazy!

I'm trying to think of the scenario for this.  Since bitcoin was about $30 at the end of February, a crash to the $50s would only impact those who bought in March and early April.  Those into both bitcoin and gold are probably not the kind to be leveraged much and there aren't many ways to obtain leverage with Bitcoin to begin with. 

So the price of Bitcoin reverses and the person now has less net wealth, sells some gold to raise cash as previous cushion went into bitcoins?    I'm having a hard time seeing that happen to any significant degree.   But if Jim Rogers is talking about this there must be some of it happening that he knows of. 

Now if he instead had said about rotation from gold to bitcoins, then that is something I'ld believe.  Like how some amount of money that used to go into gold is now going into bitcoins instead.  And without that buying of gold there was nothing else to hold the price of gold up against those shorting it.

Also, I'd like to know what is the effect of this act on the market.

Clark Moody has a calculator to tell you the slippage.  Click "Show calculators", and enter the 1,500 BTC value.  At this moment, slippage is about 2%.  In other words, a pretty trivial number.  It can vary greatly moment to moment.

The kinds of things I am talking about include: Chanel, Gucci, Louis Vuitton, Burberry, Jimmy Choo, etc.

Main issue I see with this is the high likelyhood of fakes, even if high quality I'm only after the real deal.

Seems like a natural fit, right?  Certainly any existing sellers have problems with chargebacks / high risk merchant accounts.

Are you doing market research?

It wasn't that long ago that such a day arriving seemed so far off.  With gold dropping the chances of Bitcoin hitting that in the next year or two (or less even) would not be surprising.

What's the best way to make a deposit from Canada to BTC - e? 

You can make an international wire transfer (using USDs) but it probably won't be cheap.

Another method is to open an OKPay account and wire money to them that way.
1100  Bitcoin / Press / Re: 2013-04-16 Forbes - Bitcoin: Whatever It Is, It's Not Money! on: April 16, 2013, 08:40:16 PM
he's too old to understand Bitcoin.

His age has nothing to do with it, but his target market that reads his words certainly does.   He's simply using a tired argument that exchange rate volatility is bad for a currency.  He's not incorrect, but that doesn't mean bitcoin won't succeed as a currency.   There's a difference.  He probably knows that but is describing to his audience what they want to hear.

Now what is surprising is that Steve Forbes isn't making the connection between Bitcoin catching on and that helping his cause of moving to a flat tax.   If bitcoin essentially makes income tax something voluntary (since the state will have a much harder time with enforcement of the tax laws) then a flat tax is about the only solution. 

For some reason, either he hasn't made this connection or doesn't want to share it.
