1  Bitcoin / Bitcoin Discussion / Re: == Bitcoin challenge transaction: ~100 BTC total bounty to solvers! ==UPDATED== on: July 03, 2022, 04:39:16 AM
Alright, so, heads-up:

I have tried extensively to create a machine learning model for this puzzle. No pattern exists. I'm basically categorically certain now.

I have many3090s if anyone has any more suggestions that might be compute intensive but not brute-force.

BTC FLOAT SCAN #64

another way of scanning..
Code:
import time
import random
import secp256k1 as ice
from time import sleep

t = time.ctime()
print('',t)

print('\n\n * BTC FLOAT SCAN #64 *\n')
print('\n |=========CURRENT===LINE=========||=====CNT====||=FLOAT=||=LOOP=|\n\n')
sleep(1)
print(' scanning...',end='\r')

def range_with_floats(start, stop, step):
    while stop > start:
        yield start
        start += step
       
a=9223372036854775807
b=9223372036854775808
#=========================================     
c = 1000000
d = 3846
group_size = c
#=========================================
e = 0.0000031115691002
f = 1.0000000000000000
g = 0.000001
#=========================================
total=0
loop=0
for x in range_with_floats(e, f, g):
    loop += 1
    for i in range(d):
        x += 0.00026
        xx = x
        x1 = int(a * x + b)
        key_int = x1
        P = ice.scalar_multiplication(key_int)
        current_pvk = key_int + 1
         
        Pv = ice.point_sequential_increment(group_size, P)
             
        for t in range(group_size):
            this_btc = ice.pubkey_to_address(0, True, Pv[t*65:t*65+65])
            total+=1
            if this_btc.startswith('16jY7'): # 16jY7q
                print(' ',hex(current_pvk+t)[2:],(this_btc)[:12] + '... ',str(total).zfill(12),'','{0:.5f}'.format(xx),'',str(loop).zfill(6),end='\r')
               
                if this_btc == '16jY7qLJnxb7CHZyqBP8qca9d51gAjyXQN':
                    file=open(u"BTC.Target.Info.txt","a")
                    file.write('\n ' + this_btc + ' | ' + hex(current_pvk+t))
                    file.close()
                    sleep(1)
                    exit()

        P = Pv[-65:]
        current_pvk += group_size

Sorry, what exactly is happening in this?

Is there a python code that proceeds sequentially with the binary number system and can specify the range, guys?


Why would you want the binary value over hex?

A revised effort to consolidate our compute power by means of a pool:

I know. It's not for anything nefarious. I need the data locally.

I'm looking for a developer to write a script to generate all possible private keys and write them to an SQL database. Payment available
7  Bitcoin / Development & Technical Discussion / Is it possible to obtain the public key from any address? on: November 29, 2021, 02:27:30 PM
Hey,

I need to know if it's possible to obtain the public key from any given BTC address. And if so, how?

I usually get it via the "decodescript" command hash value via the Bitcoin core, but this particular hash doesn't contain the public key, as far as I can tell.
