簡單的比特幣挖掘算法

Question

我想弄清楚簡單的比特幣挖掘算法如何在簡單的c或c＃或一些僞語言中起作用。我在http://pastebin.com/EXDsRbYH找到了一個例子，但不幸的是它不知道它的作用。我無法運行它。

假設我只有一個輸入：一個比特幣錢包「abc ...」，我想用它來開採比特幣。我需要一個簡單易懂的算法，它將在一臺機器上做一個線程上的比特幣挖掘[我知道這需要很長時間才能完成:)]

超級笨拙而無用，但我做了這個演示用途一次：

from hashlib import md5 
from random import random 
import sys 

# what to hash 
data = "Bitcoins!" 

# This is just a first run to init the variables 
h = md5(data.encode('utf-8')) 
v = h.digest() 
best = v 
best_i = data 
best_vhex = h.hexdigest() 

# x ist just a helper to only display 
# a subset of all updates (calculates faster) 
x = 0 
step = 100 

# In reality, this loop stops when the "h" hash 
# is below a certain threshold (called "difficulty") 
while True: 
    i = data + str(random()) 
    h = md5(i.encode('utf-8')) 
    v = h.digest() 
    vhex = h.hexdigest() 

    # log progress 
    if v < best or x > step: 
    msg = "%-25s | %-25s -> %s" % (i, best_i, best_vhex) 
    sys.stdout.write('\r' + msg) 
    x = 0 
    else: 
    x += 1 

    # check if new best one 
    if v < best: 
    best_i, best, best_vhex = i, v, vhex 
    print
