Young people using computers used to bring people to the Moon to dig Bitcoin, not knowing which life was 1 BTC


Dream of getting rich doesn't leave anyone. Since listening to digging / investing Bitcoin can get rich quick, people have devised enough ways to make money from precarious cryptocurrency than this stock. Products such as the Tesla Bitcoin digging system, with NES game machines with age of 30, equal to … body temperature shows that human creativity is endless.

And we have not stopped there. There was a guy who tweaked the old Apollo astronaut navigation system into an inefficient bitcoin digger.

Digging Bitcoin in the "old-school" style.

The software engineer Ken Shirriff has a long file set of old electronic revival projects. Seeing the aging IBM 1401 or Xerox Alto machine work by magic from Ken Shirriff, we can feel how old technology is, how fast the technology is growing.

Shirriff's latest project: recreating the 52-year-old machine AGC, short for Apollo Guidance Computer – Apollo Guide, used to assist us in flights to conquer the Moon.

After operating AGC (which according to Shirriff, this is the only GDC machine still active at the present time), he decided to give it a very responsible but extremely heavy responsibility: digging Bitcoin .

The AGC was peeled, with all the wires inside it being "shed".

In order for you to see how hard the AGC work will be, this is a simple version of the "digging Bitcoin" action:

The Bitcoin cryptosystem can be considered a ledger that holds all the information about who owns Bitcoin, and allows two people to transfer Bitcoin to each other. Nobody (or any machine) manages this system, so Bitcoin is very popular because of its security. But the security of Bitcoin assets is far from over: all information about the owner, the stored address is stored on every computer in the network, and no one stands out to handle that data.

Trading takes place through a "dig" process – a process that requires a lot of computing power to solve, so no one can take control of the transaction. Participants "dig" will compete with each other, find the hash value – the result of a hash function, which functions to summarize the data series into a string of numbers and numbers of a certain length.

Whoever finds the hash value will be considered successful digging successfully, successfully executing the transaction between the two and receiving a little reward. In order to find the right value, a machine must constantly test the type, finding a hash value is increasingly difficult, when the workload is calculated more and more.

In digging bitcoin, another concept to keep in mind is that the block – which gathers all the data about the transaction, the time it takes to execute the transaction, and the data that leads to the block immediately before it; Each block can be considered a page of the ledger. In a block there will be a math puzzle, the correct answer will have the right to officially put this block into the string. The speed of forming a block is about 10 minutes, meaning that every 10 minutes, there will be people who successfully solve the puzzle in the block and get bit of Bitcoin.

The blocks merge together into a blockchain chain.

This is the output of bitcoin processing with AGC.

Successfully solving a block will generate Bitcoin; Currently, a successful digger will receive 12.5 Bitcoin (equivalent to USD 157,271 at the time of writing), adding a little money transfer fee. Working 10 minutes can receive up to 3.6 billion, no one likes it.

The old AGC machine doesn't even have a microprocessor, because it was born before the processor was completed. So AGC will never dig for anything.

"The computer takes 10.3 seconds to calculate a hash value, so AGC will take a billion times the life of the Universe to successfully dig a block," Shirriff said. You know what, on Amazon there is a USB digging coin for $ 70, with a calculation speed of 130 billion hash per second.

In its time, AGC was a monster with the power to calculate 40,000 additions per second, slower than today but still enough to bring people to the Universe with the ability to navigate and control the name motor. fire.

"The AGC system owns a hash rate of 10.3 seconds for each Bitcoin hash. Currently, Bitcoin network is operating at 65,000,000,000,000,000 hash / sec"Said Shirriff. At this 65 billion billion hash, "AGC will lose an average of 4×10 ^ 23 seconds to solve a block".

With the age of the Universe at 4,3×10 ^ 17 seconds, according to Shirriff, AGC will take about one billion times the life of the Universe to successfully dig a block. He happily named this project "digging Bitcoin in a ridiculous way."

Perhaps getting rich in this way is a bit difficult. This is also a testament to how powerful the machine you are using to read this article is compared to its "grandfather". The next time the machine has "lag", give it some time to process, while sitting and pondering on how the man got to the Moon with AGC.
