There is a village of Bitt, where all the gods are shape-shifting incarnations called “people”, that is to say, people do not know which god they are.

Isolated from the rest of the country, the village’s internal economic system is backward, bartering is chaotic.

The village has an amazing white sand beach, but it is mixed with very rare red sand, and all the people on the beach (whether it is several, 1 or 10,000 people) search for one grain for about 10 minutes.

One day, a man named Satoshi Nakamoto invented a system.

As the inventor of the system, he gave himself $50, which he wrote on a one-page bill and made the first page of the village ledger.

The system rules are as follows:

1. When a transaction occurs, broadcast it to the people around you, and the people around you need to write down the transaction information in their notebooks

For example: Satoshi nakamoto bought an apple from Zhang SAN for $4.5 and told everyone around him. People around know to put in the satoshi to Zhang SAN 4.5 dollars of transaction records in their own book.

2. In order for people around you to record their transactions in their books, the payer may pay a certain handling fee to be recorded by people around him (the handling fee is not immediately given to those who record the transaction, see clause 4).

3. Villagers can record their books on a page of bills and submit them to the village general ledger, but they need to submit a grain of red sand at the same time to be accepted by the village general ledger

4. Villagers who submit a page of bills receive 50 yuan and a handling fee for all transactions recorded on the bills

Here’s a little story

Satoshi spent 4.5 yuan to buy zhang SAN an apple, and the 0.5 as a service fee broadcast out, heard the villagers quickly take a small notebook to write down.

Zhang SAN bought Li Si a cow, spent 1000 yuan, and 50 as a poundage broadcast out, heard the villagers quickly take a small notebook down.

Wang Wu looked at the sea on the beach every day, one day suddenly saw a grain of red sand, quickly recorded in the book on the top of the two records written on a page of the bill, with the red sand submitted to the village general ledger, he received 50 yuan to submit the bill reward plus handling fee 50.5, a total of 100.5 yuan.

Villagers a look, this feeling good, have gone to the beach to find red sand. But as we said before, this is an amazing beach, and no matter how many people are on the beach, it takes about 10 minutes to find one. As more and more people found it impossible to dig alone, they began to group up and set up mines.

By now, you can try to understand blockchain and Bitcoin.

One page bill = Block

Village General Ledger = Block Chain

Money in the village = Bitcoin

Find red sand = compute Block hashing (Block hashing)

Beach (several, 1 or 10,000 people searching for one grain in about 10 minutes) = Dynamic adjustment difficulty (about 10 minutes to dig a block)

Coin circle one day, the world ten years, the rise and fall of bitcoin is common, but also to choose the right way to get bitcoin, presumably the best way is now the cloud computing power mining, what is the cloud computing power mining? Cloud computing power mining is to split the computing capacity of the mining machine to sell, users can subscribe to 10-1000 computing capacity greatly reduces the threshold of mining, and the pain point of mining difficulty!
