Nakamoto has published "Bitcoin: A Peer-to-Peer E-Cash System", telling everyone about the principle and rules of the game, and then making the Bitcoin software code public:
1. Anyone can download software to participate, and can get Bitcoin rewards by participating in the tasks;
2, the obtained bitcoin can be safely and quickly paid to other people without any third party institutions (such as banks);
3. The total amount of bitcoin is 21 million;
4, this game can not be cheated by anyone, the more people participate, the more powerful the system, even any hacker or government agency can not shut down or kill it;
Yes, this is a fair "game" that has money, rights and can't do whatever it wants;
Decentralization, non-tamperable, open and transparent, international, anti-inflation
Halved in four years:
1. Initially generate 50 bitcoins every 10 minutes (the interval of 10 minutes is guaranteed by the algorithm to be stable);
2. After every 210,000 times, the single production of Bitcoin is halved, from 50, 25, 12.5... and so on, until the total amount reaches 21 million.
According to the above rules, we only need to list the calculations to get the time required to halve (210,000 times) each time:
Note: Because it is produced every 10 minutes, the number of times per year is 365*24*6
The answer is exactly 4 (years), which is the origin of the "half of four years."
Bitcoin is halved in four years to give Bitcoin more value.
