Learn the basics of the currency circle in seconds: Bitcoin
In 2008, a man who called himself Satoshi Nakamoto published an article online, expounding his new concept of electronic currency. Bitcoin was born and became popular worldwide. Bitcoin is a peer-to-peer, decentralized digital currency. So, what is the principle of Bitcoin? Let's explain it in easy-to-understand words.
Suppose there is a small village where people barter and exchange their own items for what they need.
One day, in order to encourage everyone to work actively, the village chief came up with a solution: whoever works hard will be rewarded with points, which can be exchanged for daily necessities, and at the end of the year, they can get more food. The village accountant is responsible for recording everyone's points. After the implementation of this system, everyone worked very actively, and the village chief was also very happy.
But after a while, Xiao Ming found that he worked very hard every day, but Xiao Qiang had more points than him. So Xiao Ming went to the village chief to report the situation.
After investigation, the village chief found that it was the accountant who colluded with Xiao Qiang and secretly added points to Xiao Qiang. The village chief decided to reform the points system: the accountant is no longer responsible for recording points. Everyone has a ledger. Everyone checks the points of the day together every day. Only the points recognized by everyone are valid, and the person who calculates the points first every day can get an extra point reward.
The village chief's new policy conforms to the basic principles of Bitcoin:
1. The accountant is no longer responsible for recording points. Everyone has a ledger, which is decentralization;
2. Everyone can use the points in the ledger to exchange for daily necessities or food, which is digital currency;
3. Everyone can supervise and trade with each other, which is peer-to-peer;
4. The first person to calculate the points can get a reward, which is mining;
5. If someone is afraid of offending others, the ledger submitted is anonymous, which is anonymity;
6. It is not replicable and limited.
Just as the daily necessities and food in the village are limited, the points are also limited.
The same is true for Bitcoin, which has an upper limit of 21 million.
