Bitcoin / Project Development / Re: I want to upload all public bitcoin addresses on blockchain to mysql, How?

on: May 07, 2017, 06:01:28 AM

I know it will never work. But I l would like to see if I can build my own bitcoin collider.

I found a python script that generates a public and private key. I modified it to take an input file. I increment the 77 byte exponent by 1. Then put it in a loop. I check for a transaction history using a call to blockchain.info. If a transaction is found (i know, will not happen), I write the private and public key to a file. I update the input file at the end of each run.

I want to run it against my own database, instead of making calls to the blockchain.info. As you can see from my source, I put a 20 second between each call so as not to overwhelm the api. I also run the program with a sleep time between runs.

This is how I run the program from my linux command line.
while sleep 235; do python usethis.py; done;

Would love to get this running with no sleep time.

You need inputfile.txt example input

Bitcoin / Project Development / I want to upload all public bitcoin addresses on blockchain to mysql, How?

on: May 06, 2017, 05:55:27 AM

I want to upload all public bitcoin addresses on blockchain to mysql, How? I guess a csv file of the blockchain would work. I want to use a python program to search the mysql database.

Here is the output if I find a private/public key combo.

I sent some bitcoin to the public address to see if it would work. I didn't actually find one in the wild.

Other / Beginners & Help / working on a bitcoin collider program in python, Am I on the right track?

on: May 02, 2017, 08:45:42 AM

I modified a script I found to take an input file with a 64 byte hex integer (77 integer exponent). I check for any transactions and then increment by 1 and and check again. I put a 12 second delay between calls so I don't overload blockchain.info.

Am I on the right track?

Quote from: Epileptic_Neurosurgeon on July 22, 2015, 11:30:15 AM The world economy is intertwined, the US economy is dependent on the world economy and vice versa. Naturally the world economy would suffer greatly if the US economy failed, but it would eventually recover and other economies would fill the vacuum. This was what I was gonna say. If Europe, China, or the US economy fail the effects will be felt worldwide. But things will recover. This is part of the issue today, Every region is messing with their currencies. Trying to force infinite economic growth every quarter.

Best way to predict the market is to force the market. When you want to buy, spread misinformation and fear. You can do this by using twitter. Or going to a popular forum and telling everyone your autistic brother has predicted a crash.

Mt Gox is at the top of the list. Number 2 is all the ransomware. Looks really bad on the community when bitcoin payments are demanded for extortion.

I am gonna do a garage sale. Post it in the local paper with "bitcoin accepted". You guys gave me an idea too. Maybe make a youtube video of the garage sale and show how easy it is to accept payment.

I have a list of important passwords stored away in a safe for when I die. This includes my coinbase account. I will add my multibit password to the list too. Thanks for bringing this up.

That is pretty cool. I think Bill and Melinda Gates are really into making the world a better place. Opposed to the Bill Gates from Microsoft's early days. This could help Africa become more technologically advanced. I view Bitcoin like NASA. It gets people interested in Technology and creativity takes off.
