...

I think the OP wanted to know how to find out more technical information, not get brainwashed by crackpot conjecture.

What I've learned from this thread is that the OP is so in love with defending Gox, that if you say anything remotely critical, he will insult you personally, delusionally put words in your mouth on the basis of nothing, and gets upset to the point of profanity.

This page will introduce you to the basics of what you're asking:

Difficulty basically sets the probability that any given hash will solve the block.
thanks what about scrypt algo how can i find calculator for it.

What does sCrypt have to do with any of this?

This is not a religion.

The future and value proposition of Bitcoin does not depend on people calling each other "brother" and singing around a goddamn campfire.
506  Bitcoin / Bitcoin Discussion / Re: It is possible to make a ZERO spend with Bitcoin? on: March 02, 2014, 04:27:49 PM
Recent speculation about MtGox has raised the possibility that Karpeles may have spent BTC into wallets for which he had invalid private keys.  Ie, his key generation algorithm may have malfunctioned.

I don't care to speculate about that.  However, it does raise a valid technical question...

Is there a way to test the private key of a Bitcoin wallet without transferring real value?  Ie, can I make a spend of 0.00000000 BTC to another wallet?

Obviously no value would xfer, but the transaction would get recorded in the blockchain.

Tell me, is this possible or practical as a way of doing a simple live test on a new wallet before sending live value to it?

What do you mean by testing an address? Why would you need to "test" it?



The OP doesn't really have an appreciation for how straightforward hashing a random number twice is.
507  Bitcoin / Bitcoin Discussion / Re: It is possible to make a ZERO spend with Bitcoin? on: March 02, 2014, 04:02:51 PM
But what if there is a bug in my internal testing procedure?  Ultimately the only true test that is 100% reliable is to do a live spend.

Testnet.

American regulators need to shut their stupid uneducated sensationalist pandering mouths about drugs, murder for hire, human trafficking, terrorism, etc. and actually talk about consumer protection. Do your stupid job instead of grandstand about bullshit you know nothing about on camera.
509  Bitcoin / Bitcoin Discussion / Re: It is possible to make a ZERO spend with Bitcoin? on: March 02, 2014, 03:57:57 PM
You wouldn't want to actually do something like this live on the blockchain, instead you should develop your own internal testing procedure based on the spec. The reason being that executing a spend puts your public key out there on the blockchain, which is less security for your keypair versus just having the payment address publicly known (which adds RIPEMD-160 to the mix).

If you perform a spend with the intention of keeping a balance in that address, you've basically handed the RIPEMD-160 portion of the attack to anybody who wants to compromise your keypair. Granted it's still a daunting task, but the best security practice is to never reuse an address that has performed a spend.

My exchange still has enough bitcoins to cover 95% of deposits.

What's the big deal?

It's not like 95% of customers are all going to try and withdraw at the same time.

My employees worked really hard and deserved a Christmas bonus. Not to mention, we needed new office furniture.



What you're describing isn't what "going fractional" actually means, what you're describing is just petty theft. Fractional means that you are leveraging deposits to make a return.
511  Economy / Service Discussion / Re: btc-e is also running fractional reserve on: March 01, 2014, 07:02:55 PM
I'm just going to borrow a few coins from the exchange to pay for my mansion filled with prostitutes.

I will repay those coins with the income the exchange makes next year.

Don't worry. 

You can trust me. 

 



Nobody can actually make money doing this unless they've already decided that what they're doing is going to be outright fly-by-night theft. And the risk/reward for doing something like this is irrational in comparison to the reward for actually running the exchange business.

Saying that this could possibly be going on is tantamount to saying that btc-e does not intend to actually operate, and that kind of claim needs a lot more evidence than just cynical bush-league allegations on the basis of 100% conjecture.
512  Economy / Service Discussion / Re: btc-e is also running fractional reserve on: March 01, 2014, 06:54:50 PM
It it were my exchange and I had no over-site, I'd be tempted to do this myself.

Wanting to do that is completely idiotic, because going fractional on Bitcoin does not amount to the same thing as it would with fiat deposits.

The advantage to going fractional on fiat deposits is to maximize profits through leverage, predicated on the assumption that the risk/return on lending out fiat deposits works in the depository's favor on average.

With Bitcoin, that's the most insane and dangerous proposition ever, because it isn't exactly rocket science to see from past performance that becoming illiquid in Bitcoin can result in a situation where after a large rally, the operator would never ever be able to buy back adequate reserves, because the returns in Bitcoin itself were higher than anything they could've ever done through leverage. This could only ever happen in a situation where you had a robust Bitcoin credit economy where returns themselves were denominated in Bitcoin directly.

Basically there is no way to do this without actually being a straight Ponzi. Trying to operate a plan like this amounts to massively shorting Bitcoin at all times (without customer consent) risking shorting into an enormous rally that ends you.

The notion of forking for reasons that relate to establishing certain balances is the most dangerous idea imaginable and will completely kill Bitcoin dead. Arbitrarily adjudicating the status of certain parties' coins turns the Bitcoin userbase itself into a centralized counterparty and leads down the slippery slope of deciding winners and losers in fork bailouts.
514  Economy / Speculation / Re: Wall Observer BTC/USD - Bitcoin price movement tracking & discussion on: February 26, 2014, 10:58:47 PM
It would be funny if it would turn out that Mark Karpeles is in fact Satoshi and he did create bitcoin just as a simple scheme. 1) Create crypto 2) Create exhange 3) Start buying your own crypto and wait when someone sees that someone is buying and will also join in. Soon more will join.
But the scam just got too big and really out of hand.

 Cheesy Cheesy Cheesy

Sure, except that the original whitepaper reads as though its written by a genius, and this guy is full retard in every imaginable way.

is it a wallet for Machin?

Stop it, you created this yourself without his consent on that website.

517  Bitcoin / Mining / Re: deepbit.net. Pay per share or Proportional? Which is better? on: February 26, 2014, 08:47:34 PM
Normally if they have it structured correctly, proportional should pay more over longer timescales, because pay-per-share ordinarily requires a higher pool fee to compensate for potential bad pool luck.

Another aspect to the story is that if this is a straight proportional, that might be undesirable if you intend to mainly just mine there, because proportional arguably can incentivize pool hopping (i.e. you switch to a pool the moment it solves a block, so that if another block gets solved quicker than you would expect from chance alone, the shares you've contributed to that block are relatively more valuable). If their proportional is a PPLNS then that notion isn't a concern.
518  Bitcoin / Bitcoin Discussion / Re: How do we prevent money laundering and assasinations? on: February 24, 2014, 11:20:07 PM
Whenever regulators shoot their stupid mouths off about drugs, money laundering, assassinations, human trafficking, etc., I feel like they're flushing a tremendous opportunity down the toilet to build real credibility and support from the public by instead talking about consumer protection and prosecuting fraud.
519  Economy / Service Discussion / Re: Here's my gox theory on: February 23, 2014, 05:16:16 PM
Gox is inviting all the wild speculation and innuendo you can possibly imagine by taking forever to resolve a fairly straightforward technical issue, lying about the nature of that technical issue to begin with, and offering zero helpful communications whatsoever.

The market is pricing Gox's credibility right this moment vis-a-vis the spot price, and it doesn't look pretty. There is no way in hell Gox can sustain such a low price unless the overwhelming majority opinion of market participants is that those cheap coins will never materialize.
520  Economy / Speculation / Re: Wall Observer BTC/USD - Bitcoin price movement tracking & discussion on: February 23, 2014, 05:05:08 PM
Observing your charts from a distance makes it look like you are always right (of course hindsight makes that easy). Zooming in, it looks like if you use the indicator at the bottom, you are making the buy/sell very late (most of your arrows are not perpendicular, the bottom indicator lags the actual price movement). Considering trading fees, I can't imagine you are making enough money here to justify the risk for any of these positions. One wrong call will wipe out all of your profits from the previous multiple correct calls (even if you've called them perfectly).

EMA indicators always lag price movement, because the price movement has to happen in order to register in the indicator's arithmetic. That's totally normal, TA is not precognition, it's reacting to what the graph actually does. These indicators are astonishingly accurate against Bitcoin price movements in a way that you don't normally see with other asset classes.
