Introduction
This is a fun-only project, just to do something fun while drinking amazing cold Nescafe-Shake.
So how it works? SecureRandom create 32bits random hex string. This string is used by Money-Tree gem to make Master Node of Bip32 HD wallet. I could just let money-tree to create random seed, but where's my fun then?
Let's start!
You can add gems into Gemfile, then use it for luckybastard, but most of ruby devs have this gems installed. In case you don't have:
# install gems localy with: gem install money-tree colorize or # create Gemfile and add gems # run `bundle install` to install them gem 'money-tree' gem 'colorize' Now create file called luckybastard.rb and open it. Write shebang (because I guess you're on linux, if you are on windows, go install linux), and require needed dependencies.
#!/usr/bin/env ruby require 'securerandom' require 'money-tree' require 'open-uri' require 'colorize' require 'net/http' MoneyTree and Colorize are gems we need to install, and other dependencies need to require.
Let's create our class LuckyBastard
# class LuckyBastard - code is part of this # max-time to sleep if request fail SLEEP = 2 # default type of checking address TYPE = :sent def initialize( max_sleep = SLEEP, type = TYPE ) # count all requests (generated seeds) @counter = 0 # this counter reset on 10, to show in terminal @count = 0 # type of address-check @type = type # is loop paused @work = false # max_sleep between fail requests @pause = max_sleep # start time @start = Time.now.to_i end After initializing variables, it's time to make methods to get/set/use them.
# set max_pause time def pause=(max_sleep) @pause = max_sleep end # get max_pause time def pause @pause end # check is paused or not def pause? @work == true end # start or stop loop def pause! if pause? then start else stop end end # stop loop def stop @loop = false end # start loop if paused (or not) def start pause! if pause? until pause? do execute end end # from check(address) def success? @balance > 0.0 end That's all for public methods. Now we need LuckyBastard#execute (used in #start). That method will use another to generate seed and check for address balance. This methods should be private.
Private methods you can't call directly. You put them inside public method to run.
# ... public code private # called from #start def execute # generate random keys random_private_key! # check address balance check @address @count += 1 # if balance is more then 0.0 if success? @end = Time.now.to_i - @start # write valid data to file and print them write_to_file(@address, @balance, @hex_seed) puts "[*] Valid seed found in #{(@end / 60)} minutes".yellow puts "[!] Enter 'Q' to quit, or any key to continue (q/Q):".yellow # get answer from input, exit if include q/Q answer = STDIN.gets.chomp %w[q Q].include?(answer) ? exit(1) : start # when fail, print data if 10 seeds generated elsif @count >= 10 # add previous seeds to total counter @counter += @count # clean screen and print number of generated seeds system 'clear' or system 'cls' print "\n >> Looking for [".green + "#{@type.to_s.upcase}".yellow + "]".green puts " coins on random address".green puts "\n " +" #{@counter} ".black.on_yellow + " random seeds checked...".yellow puts "" # print fail address data, do not save write_to_file(@address, @balance, @hex_seed, save: false) # reset count, so we can count next 10 seeds @count = 0 # sleep random time, we defined maximum sleep rand(pause) end end def random_private_key! # generate random 32bit hex string @hex_seed = SecureRandom.hex 32 # make new master node, and get address @address = MoneyTree::Master.new(seed_hex: @hex_seed).to_address end def check(address) # define to check for `received/sent` by address type = @type.to_s url = "https://blockchain.info/q/get#{type}byaddress/#{address}" data = Net::HTTP.get URI url # get balance in float return @balance = data.to_f # if request fail, sleep 1 min and repeat rescue puts 'request timeout, repeating process in 60 seconds...' sleep(60) and start end def write_to_file(address, balance, seed, opt = {}) @data = " #{Time.now.to_s}" + "\n" @data += "\n Address: #{address}\n Balance: #{balance}\n HexSeed: #{seed}" # do not save if option save is true (for invalid seed) File.write("#{address}.txt", @data) unless opt[:save] == false # print red for fail, green for success (balance > 0) clr = success? ? :green : :red puts @data.colorize(clr) end After you put this code inside LuckyBastard class, you can write one more method as a shortcut to run loop
class LuckyBastard # all previous code here def self.start!(max_sleep = 2, type = :sent) LuckyBastard.new(max_sleep, type).start end end You need a way to run it from terminal. Without arguments print help instructions, which tell us to run with --start, and to add --sent if we want.
# check for received coins unless args include `--sent` type = ARGV.include?('--sent') ? :sent : :received # start if args include start, or print help if ARGV.include?('--start') system 'clear' puts "\n Starting random seed generation..." LuckyBastard.start! 2, type else puts "\n Are You Lucky Bastard?".green.bold puts " Generate random hex seed and find out!".green.bold print ' ' 50.times { print '='.green } and puts puts " Get received by address:".white puts " $ ruby luckybastard.rb --start".light_green puts " Get sent by address:".white puts " $ ruby luckybastard.rb --start --sent\n".light_green end
