The betrayal who performed 'Mining of Bitcoin' with the computer used for the Apollo project appeared
The Apollo computer , used to control the spacecraft's navigation functions automatically by the US Apollo program , which achieved the world's first lunar manned landing, and for astronauts to confirm and correct flight information, is a modern computer and It is surprisingly low spec in comparison. However, with this low-spec machine, a virtuous man has appeared to be at the forefront of the business, “cipher assets (virtual currency), mining of Bitcoin ”.

The Apollo induction computer, developed at the MIT Institute of Instrumental Engineering (now Charles Stark Draper Research Institute) in the 1960s, played an important role in the Apollo project, but it is now at a level of antiques. Software engineer Ken Schliff has successfully repaired the broken Apollo computer and got it up and running again. According to Schiff, the Apollo induction computer is the only working Apollo induction computer in the world.
Using such an Apollo induction computer, Schiff thought about using the retro computer for 'Bitcoin mining', a very modern task. Bitcoin mining is now a state-of-the-art business using a large amount of computers, and the world's largest Bitcoin miner buys more silicon semiconductors than NVIDIA and builds Bitcoin's dedicated machines.

While implementing the mining algorithm for Bitcoin on a 15-bit computer developed in the 1960's was a bit harder, Schriff made it possible to mine Bitcoin with the Apollo induction computer.
Bitcoin mining uses the SHA-256 algorithm, which provides the energy needed to calculate the values called the hash values that make up the block chain, allowing Bitcoin minors to earn Bitcoin for compensation. . As a matter of course, the Apollo induction computer can not compete with the modern computer in terms of specs, and it took 10.3 seconds of computation time per hash. By the way, it is likely to be able to calculate 130 billion hashes per second with the USB stick type Bitcoin mining machine which can be purchased for about 13,000 yen.
According to the calculation, it seems that it takes 400 Zeta (4000 秒) seconds for the Apollo induction computer to dig the first Bitcoin, and Schriff said, 'It takes a billion times the age of the universe to mine the Bitcoin. It will take, 'comments.
Schriff is a person who once tried 'Bitcoin mining' with 'Manual calculation using paper and pencil'. The calculation speed that Mr. Schiff started out at that time was 0.67 hash per day, and it turns out that the calculation speed of the Apollo induction computer is beyond human speed although it is a retro computer.

In addition, Schiff also performed Bitcoin mining using IBM 1401 , a computer announced by IBM in 1959, at this time using a punch card to perform hash calculations. The calculation speed at this time was 80 seconds per hash, and Apollo induction computer can perform Bitcoin mining about eight times faster than IBM 1401.

You can see in the following movie how Bitsoin mining is actually performed by Apollo induction computer. You can see the numbers on the display to show that you are doing calculations for mining.
