One of the reasons why Bitcoin is so brilliant is that FRB (Fractional Reserve Banking) is actually much more difficult than with any other monetary system. Even with gold it's very much possible even though the base money (gold) can't be expanded. In a fiat money system even the base money can be expanded forever and ever, which is exactly what the central banks do.

With Bitcoin there is a radical difference. The base money is essentially as fixed as gold but the big difference is that it's independent of centralized institutions. With Bitcoin there is a very limited need or advantage to deposit your money anywhere. This is why a large portion of Bitcoin transactions will always move outside the banks and this will make it impossible to practise fractional reserve lending in any major capacity.

It will of course be possible and even likely, but instead of banks having 10% reserves, Bitcoin banks will have much larger reserves. This is of course a VERY GOOD thing, don't let anyone tell you otherwise. Tell that "economist" to read something else for a change. Recommend Schlichter's "Paper Money Collapse".

Fair point.  Smiley  But for Bitcoin to be successful, it should be widely accepted.  The point being contested is whether the gov'ts would even allow Bitcoin to grow given they control the nations' laws and armies.  Just like bitTorrent exists but cannot/have not eliminated copyrights.

Bitcoin can be lent, but cannot create credit in the way that fiat currencies can.  Currently, large economies are making up (creating from thin air) huge amounts of currency to buy debt and other assets, manipulating the economy.  This is not possible with BTC which is one of the major advantages of it.  However, this is not the way the economy currently works.  BTC will give users a guarentee that it will not be devalued by a central bank printing more BTC, BUT it does make it less flexible for those central banks and will therefore never be adopted by them.  This is a currency of the people for the poeple!

Bitcoin can be used to create credit as long as two parties agree on terms with Bitcoin amount as notional.
23  Economy / Economics / Re: Doubt about Bitcoin's growth potential on: September 06, 2012, 05:20:47 PM
Ehh, firstly, it's the easiest thing in the world to create bitcoin-denominated credit. This is being done all the time on this forum. Of course because of the limited nature of the resource, no sane person wants to owe anyone huge amounts of bitcoins.

Bitcoin is not even supposed to replace inflationary currencies, but complement them. It is not clear if bitcoin can ever be technically scaled up enough to be the sole exchange medium in the world. On the other hand, sovereign nations need to be able to issue their own inflationary currencies through their central banks just to continue functioning, at least in the current environment.

I could see Bitcoin eventually replacing some "specialty" pseudocurrencies, like the SDR, if it really takes off. It won't ever replace fiat.

I and my friend agree... but what does that mean for it's growth potential?  So (he asks) why even have a new currency, if Bitcoin was supposed to get rid of the current hyper-inflationary system.  It is not really fulfilling its purpose, it is just staying there.  Right?
24  Economy / Economics / Re: Doubt about Bitcoin's growth potential on: September 06, 2012, 05:17:38 PM
The unpayable debts will be defaulted, either outright via repudiation and/or dissolution of governments, or via inflation. The consequences of these defaults are not avoidable but Bitcoin represents a way to prevent the situation from happening again.

How do you see that happening, how do you see Bitcoin forcing all the debt that is currently in the system to get defaulted?

The idea that Bitcoin will force the "repudiation and/or dissolution of governments" is a far-fetched notion.  They still have the ability to "make laws" at will, and to their own preservation.

This may be a bit "back to basics" for this thread, but I am going to give it a shot,and see what responses I get:

I am trying to TEST/SHOW bitZino to be Provably Fair to myself and a friend.

So, without programming, and using available third-party (online) tools, how can I CHECK the sequence of shuffles, and how they get manipulated by the player's secret re-hashing (cutting) of the deck.

Is this even possible?

-----------------------

I hope this is not too complicated.  I just want to be able to walk-through, and VERIFY that which you claim is "Provably Fair"

This is a great idea! As you mentioned, Dooglus did write a python script which verifies the secret and outputs the final shuffle of the deck given the Hash(secret), secret and the client_seed. Additionally, we have a javascript hand verifier located at https://bitzino.com/about/fair. If you are inclined to take a deeper look at the code for our verifier, you can view the source of that page and see the javascript verifier - it's just 100 lines of well-commented code.

However, I understand that you may want to verify on your own without relying on having coding expertise or relying on code that is hosted on our own website. To that end, I've outlined the steps to do this below: (unfortunately, there will be just a little bit of "coding", but it's really just copying and pasting certain commands into a javascript console. This is necessary because there isn't an online implementation that I could find of the Fisher-Yates shuffle algorithm)

Step 1: Verify the Hash(secret) is derived from the secret

After playing a hand of any game at bitzino, go to http://www.movable-type.co.uk/scripts/sha256.html, and copy and paste the Secret in to the box. Click on the "Generate Hash" button, and verify that the hash generated on that website matches the Hash(secret) you see on bitzino.

Step 2: Generate the seed from the client_seed and the server_seed

While still on the same website, copy and paste the client_seed into the box, followed directly by the server_seed (the server_seed is part of the Secret). E.g, if the client_seed is "ABC", and the server seed is "123", the box should have "ABC123" in it. (Also, make sure you're copying the client_seed from "Last hand" on bitZino, not from the "Next hand"). Click on the "Generate Hash" button. Now, keep this page open, because we will be using this Hash later.

Step 3: Set up a javascript console with the Mersenne Twister function

Go to http://jsconsole.com. This is a javascript console, and it's where we'll be completing all of the following steps.

Copy and paste all of the code from https://bitzino.com/static/MersenneTwister19937.js into the javascript console. This will initialize the Mersenne Twister function which will be used later on.

If you'd like to verify that the above code is indeed a pristine copy of the Mersenne Twister, you can download the original zip file from http://www.math.sci.hiroshima-u.ac.jp/~m-mat/MT/VERSIONS/JAVASCRIPT/java-script.html

Step 4: Seed the random number generator

Type the following commands into the jsconsole:

Code:
var seedString = "<hash value from step 2>";
var seed = parseInt(seedString.substring(seedString.length - 8), 16);
var mt = new MersenneTwister19937();
mt.init_genrand(seed);

Note that the first line of code isn't actually <hash value from step 2>, you should replace that part with the value you got from step 2.

Step 5: Set up the initial_shuffle

Create a variable in the jsconsole that is equal to the initial_shuffle from bitzino. (The initial_shuffle is part of the Secret).

Code:
var initialShuffle = "<initial_shuffle>";

Step 6: Reshuffle the deck using the Mersenne Twister RNG, and the Fisher-Yates shuffling algorithm

Copy this code into the jsconsole:

Code:
function shuffle(deck_string, mt) {
    var tmp, new_deck = deck_string.split('');
    for(var i = new_deck.length - 1; i > 0; i--) {
      r = mt.genrand_int32() % (i + 1);
      tmp = new_deck[r];
      new_deck[r] = new_deck[i];
      new_deck[i] = tmp;
    }
    return new_deck.join('');
 }

shuffle(initialShuffle, mt);

At this point, the jsconsole will spit out a value that should be identical to bitZino's final_shuffle.

Final thoughts

I really wish there were an online Fisher-Yates/Mersenne Twister card shuffler, so that every step in this process would be as easy as step 1. If anyone

does know of one, please let me know so that I can make this process easier! I also recognize that you are still depending on a lot of code that is just copied directly from me, but I think the fact that it
's posted here publicly should show that it is honest, and does what it says it does.

I hope this helps!

Thanks  so much, this is EXACTLY   what I/we were  looking for!

You have officially SILENCED  my sceptic friend!  Peace and quiet at last!! Good Luck making great   waves in the gambling word...and please do be careful with your  COLD STORED COINS!!!

---------------------
I saw the python script, but I cannot run that

I am thinking along the lines of taking your first shuffle, hashing it somewhere like:

http://www.movable-type.co.uk/scripts/sha256.html

getting a hash result which I (myself) manually or using some other tool like excel or something to do whatever it is that you do to "cut" the deck... and then finding the sequence of cards that you dealt, and had the same SHA256 hash as what is shown as "proof"

And then, I would like to hash the final sequence using the above site, or some other one that is not connected to you, but I can easily access without programming.

-----------------------

I hope this is not too complicated.  I just want to be able to walk-through, and VERIFY that which you claim is "Provably Fair"

-----------------------
I do believe you, but can you also show me how I can do the checking MYSELF!? Thanks.  Smiley

27  Economy / Economics / Doubt about Bitcoin's growth potential on: September 04, 2012, 06:32:38 PM
Please help me understand/explain to an economist friend of mine...

He argues that Bitcoins have no chance in global success because a this system be used to create credit.

Bitcoins cannot be used to leverage. --> You cannot use Bitcoins to create credit.  ---> It can't replace existing credit already created by the current system.

For Bitcoins to be successful, it has to be able to replace the existing debt!


Please help me:

Where is he right/wrong?
28  Economy / Services / Re: Beijing on Bitcoin (a new holiday experience) on: July 18, 2012, 02:00:28 AM
This is to EVERYONE who is thinking about visiting Beijing!

CIYAM helped us out in Beijing!  They are a super team, and very VERY RELIABLE!

I hope that people will have a chance to meet/contact you while in Beijing because I cannot think of a better BITCOIN-FRIENDLY BASE for people to start their exploration of Beijing! 

Specifically, with a little bitcoin "deposit" CIYAM helped us go through the gruelling/feared Tourist Visa Extension ordeal with the Public Security Bureau (PSB).  Actually, having our hands held, and also having a cool 21,000 RMB cash ($3000 USD) from CIYAM to deposit/secure/lock into a bank account it actually became a smooth, and dare I say, 'okay', experience, where in the end we had two tourist visa extension applications on the way in only  days of fussing with the beaurocracy  Smiley

THANK YOU SO MUCH!   Cheesy

Oh, and great thanks goes to the Bitcoin technology, which also made securing our deal really easy! 

On a side note, if you are too lazy to research what CIYAM is upto... in a few words, I can say that they are definitely upto A LOT OF GOOD, and hopefully, the genious behind CIYAM will shine some very bright and energizing light onto the Bitcoin community.   (oh, I am not going into any details as it is TOO TECHNICAL, but sure sounds good!)

I can hardly wait to see how all your efforts pan out!  GOOD LUCK!

Cheers everybody Smiley

Here is their page...

I have offered to help them process BTC payments.  It will be about 3 BTC for the event, people will get an e-ticket.

The organizers know about it and will confirm the above! Smiley
31  Economy / Services / Beijing night life meets BITCOIN on: July 04, 2012, 02:03:30 AM
Not sure who to write to, or where in the forum would be appropriate, I convinced a party organizing company who would sell tickets to their next event in Bitcoin for July 14!

Does anyone know how I could best reach the Beijing/Chinese Bitcoin community to let them know about this?  I think it would be a great way to promote Bitcoin, by letting people to have a chance to buy tickets.

The event is a Mud Wrestling Contest (for girls) to promote a new bar.  They do not have the "We accept Bitcoin" logo, yet... but once they see a few sales happen (which I will help them with), they will be even more interested! Smiley

37  Bitcoin / Bitcoin Discussion / Re: Bitcoin in France: first legal decision directly related to Bitcoin? on: September 05, 2011, 09:41:17 AM
I am not qualified to judge what outcome would be best for Bitcoin.  Perhaps it's best to ask ourselves what outcome would be most desirable for those who oppose it?

There are prior examples of informal opinions from the government agencies - here is one:

Quote
HMRC, the UK government's tax-collecting body, says people do not incur a tax liability when trading in bitcoins as long as they do not turn their profits into regular cash. Once conventional money is involved, however, the income could become taxable, HMRC told New Scientist.

source: http://www.newscientist.com/article/mg21028155.600-future-of-money-virtual-cash-gets-real.html


I agree that it may lead everyone on a more clear path if we try and follow the path the opponents may try and take.  But to add a little confusion, it is also nice to see them chasing all the new ground breakers running wild Smiley

All in all this is a great "chase" all around!
38  Other / Beginners & Help / Re: GUIMiner help on: August 30, 2011, 04:20:50 PM
TYDIRocks messaged me that when he restarts GUIminer, the window is again off of the screen.  Here's a couple solutions:

  • After using the above method to get your window back on the screen, menu File -> Save settings
  • Modify the .ini file:
    Close your GUIminer (make sure you close the one in the tray also, don't know how many times I've had two or three instances running before I remembered to close those, too).

    Look here:
    C:\Users\YourUserName\AppData\Roaming\poclbm\

    and double-click: poclbm.ini

    towards the end of that file I found this:
        "window_position": [
            250,
            250,
            448,
            279
        ]


    I'm guessing yours are such that it appears off of the screen.  Change yours, save it, and re-start GUIminer.  Hopefully it will be on your screen now.

HEEEY, THANKS!  I had the same problem.  These were the numbers in my ini file:

"window_position": [
        -32000,
        -32000,
        445,
        314
    ]

so even using the right-click>move made no difference because I couldn't move 32000 over to see the window as I moved the cursor around.

Thanks.  I changed the numbers to what you had, and voila!

40  Alternate cryptocurrencies / Altcoin Discussion / Re: IXcoin -- enough is enough! on: August 19, 2011, 10:32:59 AM
I remember a presentation or podcast (i think it was Gavin's) that they said that in the future they may have bitcoin currencies for different parts of the world... asia, africa, europe etc...

They made a bit of sense, and these new ixcoins et al may just be a good test-bed to see if all that is really worth it.

From a security perspective though, i think this would actually create a whole bunch of weak cousins to Bitcoin and be taken out one at a time by the big guns of whomever doesn't like what is going on here.

It is super interesting to see this starting and seeing where it will end!

I LOVE BITCOINS and all it's cousins too!!! I just hope the family doesn't get taken out by an evil OVERLORD... I don't know this, but from all the cool conspiracy movies out there, it seems to me that these evildoers exist, so security is a concern, and so bitcoin is the toughest nut to crack at the moment.  I just hope that ixcoin will not be used to chip away at bitcoin's hard shell!!!

Gggggrrrrrrrrrrrrrrrrrrrrrrrrrrrrhhhhhhh
