It is not clear who or by whom this puzzle was created, but there are many "Satoshi Nakamato" rumors around. That's why we need to know what its real purpose is, not who created it.

The main purpose of the puzzle is to prove the cryptographic and technological power of Bitcoin. Because in fact, each puzzle only allows us to search in certain small areas. As of today (April 23, 2024), Puzzle 66 has not been found yet. With today's technology, we cannot find a specific key in a small area with a certain area. This proves to us how impossible it is to decipher an ordinary Bitcoin private key.

Any ordinary Bitcoin private key is just a 256 Bit number. So the total number of keys is actually 2^256 (2 to the 256th power). The hardest puzzle is only 2^160. The easiest puzzle currently waiting to be solved is 2^68 and has not been found yet as of March 31, 2025.

Description

In 2015, a cryptographic puzzle was created to demonstrate the vastness of the private key space. The creator sent increasing amounts of Bitcoin to addresses with keys in specific ranges:

• 20 ≤ random key < 21 — 0.001 BTC
• 21 ≤ random key < 22 — 0.002 BTC
• 22 ≤ random key < 23 — 0.003 BTC

Currently, private keys #1–67 and every 5th key up to #125 have been cracked.

Timeline

• 2015-01-15: Initial transaction created with 256 Bitcoin addresses.
• 2017-07-11: Funds from addresses #161-256 moved to lower range addresses, increasing their value.
• 2019-05-31: Creator adds 1000 satoshi transactions to select addresses for comparison.
• 2023-04-16: Unsolved puzzle prizes increased by 10x. Puzzle #160 now worth 16 BTC.
• 2024-09-12: Puzzle #66 (6.60126013 BTC) solved, with funds partially transferred.
   

Now today with the power of a standard computer, you can solve the first 40 puzzles in under a day.

Today, and with more modern methods, the amount possible has increased exponentially. This puzzle was to serve more of a timer then a proof of security. When quantum computers can do 256 cubits there will be no security in this any longer. 

There was also another element to this and that was time combined efforts and memory capacity. 

I will be going over this and many other things in this guide. I am hoping to show the public how this all actually works. Bitcoin's original purpose will always be rock solid. An Anonymous transfer service beyond prying eyes and overreach. It was made in response to Violations of Privacy of everyday people by Governments and those that regulate and try to control. It was never meant to be a store of value.

This was due to the fundamental flaws of the key-space size vs our exponential growth with technology. 

256-bit encryption is only secure because people do not feel comfortable with the large numbers. Many cannot actually count past a trillion, quadrillion, ...... to a google. Yes, Google is a number. Many forgot that back in 2010 when miners got 4 bitcoin every 10 min on normal machines, that we all had to do this ourselves. We did not have apps or programs to do any of this. Anyone that dealt with Bitcoin back then were required to understand basic coding and some of the basics of Bitcoin itself. 

Many have forgotten these things. 

This is to teach people the basics and most up to date methods of solving puzzle and much, much more.

Programming basics: Most Programming languages are different syntax, nothing more. The programs and algorithms are just math. using different equations from different libraries and passing info along. I will be showing all examples in python. Python is simple and easy to use for a way to show how the programs work. For those that do not want to download Unknown software you will have opportunity to see the script and libraries being used and how to edit and verify all results. For those that run these puzzle sites these things can be used to increase speeds for their searches by a factor of 10-100 x current benchmarks.

Understand this is meant to teach and inform the public of what is to come. I do not endorse hyping or promoting these things for get quick rich. The bitcoin price is what it is in the current market and the prizes are what they are. This is is to show that solely based on computing power the clock is running out. All investors will lose in end. This does not take away from original purpose only as a way to manipulate market trends and as a source of get rich quick.

I will also show how anyone can Start to Finish Process Billions of Keys every few seconds. I will be adding videos and test cases based off known variables and standard store-bought midrange PC. Since Certain Parts will require a lot of data as we go along, I will be updating this in sections. 

From there, I will be moving onto to more advanced methods and many other things not considered or tracked. Many of the vulnerabilities will be gone over from early days with Android Fiasco to Current. To understand the flaws, all of them have to be examined and discussed. 

I will be updating this over the Month of April 2025. 

As I go through, I will be adding instructions on how all can use very simply. Hopefully it helps everyone understand and allow people to understand this will come to end as a store of value.
