641  Alternate cryptocurrencies / Altcoin Discussion / Pi Coin on: August 11, 2013, 01:36:33 AM
A new coin could be created using generation of the digits of pi as measure of computational work.Pi is an irrational number and can be written as generalised continued fraction as --




Recursive function implementing 1st continued fraction for n iterations
Quote
float rec(float x,int n){
        float ret;
        if(x>=n)
        ret=1;
        else
        ret=(1+2*x)+((x+1)*(x+1)/rec(x+1));
       
       
        return(ret);
        }

int main(){
    float x;
       
    x=4/(1+(1/rec(1,8)));     //here n=8
    printf("\npi=%f",x);
   
 
     return(0);
     }

Here 8 iterations produce first 3 correct digits of pi.


It can be seen that as the number of iterations are gradually increased,computational complexity increases exponentially.Block reward could be adjusted accordingly.

Verification of n th digit can be directly found using  Bailey–Borwein–Plouffe formula. The formula can directly calculate the value of any given digit of pi without the need to calculate the preceding digits.

Attempt and result of obtaining 10 Trillion digits of pi

Just pass the parameters in the getnewaddress() call.

Code:
$json = $bitcoin->getnewaddress("Account_Name");

Thanks for help.

One thing is quite obvious bitcoins is powerful financial tool, which will first destroy present system and then used to rebuild and establish new financial system for the whole world. Once bitcoins become dominant everybody will rush to join. In bitcoins I do not means exactly "bitcoins". Some new and more advanced cryptos will be created in near future, little doubts about that.

At the end, if a government regulated/ approved Bitcoin exchange comes into play, it may override all other Bitcoin exchanges and become a larger entry point.

Maybe that is where the government can also see its profits coming in while allowing a free market for Bitcoin. Through taxing/ earning a margin on trades.

Any thoughts on that?

Yaa, people should form bitcoin party in the same way as the pirate party of Europe.Have some legislations in favour of bitcoin or even including bitcoin as an alternate national currency.

@subvolatil What does cryptoanarchy aims to achieve with respect to centralized control of govt. ?
654  Local / Off-Topic (India) / Re: Looks like they are not getting Bitcoin on: May 28, 2013, 06:44:59 PM
Here I have mentioned domestic transaction.

what difference it make, if it domestic or not, how can you prove with bitcoins that it was in fact domestic transaction. If Indian government still ignoring this biz, just because it has no any significant volume. if volume increase they will act 100%.

If bitcoin was mined in India and it can be proved, it means its domestic.

Even if govt. wants to act tough, after significant increase in volume,how will govt. dismantle sites and exchanges on tor and i2p like atlantis and silk road ?

Is there a way we can reclaim our language back (writing as it is spelt) instead of following British orthodoxy ?

For example

Ram ->Rama

Krishan ->Krishana

What are the three broad categories of applications of public key cryptosystems ?

Question asked yesterday in Information Security paper of of Computer Engineering.

"cryptosystem"  reminded me quickly of bitcoin,and I mentioned it,hoping that examiners are familiar with bitcoins  Wink

Bitcoin is a digital commodity.Selling or buying a commodity on peer to peer level is legal,as long as the seller is paying tax for it (if he includes that amount in his income).Registry of a transaction is only needed when the commodity is regulated by govt., like arms,vehicles,immovable property,stocks,bonds etc.

If I want to sell a LED TV to my friend.It will be totally legal,if I pay tax, for the money I got.If my friend smuggles LED TV to other country, he would be held responsible for smuggling not me.

Assumption: Commodity is created in India and trading is done within India.So, no question of money laundering and illegality.

So,If someone proves that certain amount of bitcoin was mined in India, and trade it on above conditions, within India, for rupees,it would be perfectly legal,until the govt. makes it mandatory to register domestic bitcoin transactions.

Full quote (also regarding questioning religious authority)

Quote
"Do not believe in anything simply because you have heard it. Do not believe in anything simply because it is spoken and rumored by many. Do not believe in anything simply because it is found written in your religious books. Do not believe in anything merely on the authority of your teachers and elders. Do not believe in traditions because they have been handed down for many generations. But after observation and analysis, when you find that anything agrees with reason and is conducive to the good and benefit of one and all, then accept it and live up to it."
