Bitcoin distributed database
The total number of bitcoins is 21 million
in 2009, when bitcoin was born, block reward was 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25
when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million

monetary characteristics
1. Decentralization: bitcoin is the first distributed virtual currency, and the whole network is composed of users without a central bank. Decentralization is the guarantee of bitcoin's security and freedom
2. Global circulation: bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin
3. Exclusive ownership: private key is needed to control bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself
4. Low transaction cost: bitcoin can be remitted free of charge, but a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster transaction execution
5, no hidden cost: as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay
6. Cross platform mining: users can explore the computing power of different hardware on many platforms
unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million.
Every other time, the bitcoin system will generate a random code on the system node. All computers in the Internet can search for this code. Whoever finds this code will generate a block and get a bitcoin. This process is often called mining
at present, one bitcoin is divided into eight decimal places based on the current data structure, that is, 0.00000001btc. The smallest unit of bitcoin g by miners is 0.00000001btc
generally speaking, bitcoin is like a gold mountain with a total amount of 21 million gold coins. To get it, players need to use the computing power of the computer to calculate a group of numbers according to the existing algorithms

Why do small enterprises need law and large enterprises need law? Because enterprises need high human cost to improve, supervise and implement the management system. And the department work of small enterprises is not saturated, so the management can not proce benefits, so the boss is unable to support the human cost. If there are too many managers in an enterprise, not only the boss will not make money, but also the enterprise will be in debt. Basically, because the management has the final say, the rule of law management is not effective. For example, foreign employees can leave work without asking about the company. Is Chinese enterprises OK? A lot of boss's private affairs have become employees' work. After work in the evening, maybe the boss will call you back to work overtime. Can the staff not go? Can the boss stop calling? No, because the enterprise is too small, there are too many things, and it's too urgent. The boss is busy, but who doesn't he call you? This is China's national conditions. Foreign employees can shut down after work. Chinese employees can try to shut down. Maybe they will ask you to pack and leave the next day. Therefore, Chinese enterprises should not blindly learn from foreign enterprise management mode, because you are in China, not in foreign countries
Why do small businesses need to be governed by people? Because most small business owners can't afford to pay high wages, most of the talents they recruit are employees who are attracted by their own human relations. People help the boss to work regardless of pay for their emotional relationship. If the boss controls everything and doesn't trust the employees, who else will want to work with you. Therefore, the success of small businesses basically depends on the boss's personality charm in the leaders and influence people, rather than on the system in the managers. Although this kind of management method is unscientific, it is efficient. As a start-up enterprise, the effect is more important than the truth, so the little boss must not superstition what too deep enterprise management, suitable is the best
Why do large enterprises need the rule of law? Because the enterprise is big, there are many people, the boss's personal ability is limited, his language and behavior influence is also limited. If the enterprise does not have an effective management mechanism, then many important documents or important decisions of the enterprise can not be effectively implemented or communicated. There will be a big difference between what the employees do and what the boss thinks. So large enterprises need the rule of law. In addition, the advantage of the rule of law is to solve the unfair phenomenon of enterprises. Let employees compete and grow in a fair, just, open, reasonable and legal market environment. We have the responsibility to bear together, the fault to punish together, the goal to struggle together, the achievement to share together
the problem with most enterprises in China is that the boss does not know under what circumstances the enterprise should be governed by man and under what circumstances the enterprise should be governed by law. Because the development of Chinese enterprises is basically a process from the rule of man to the rule of law. Too early or too late rule of law will be detrimental to the development of enterprises. Therefore, too many enterprises in China either go bankrupt under the rule of man or disappear under the rule of law. Because the rule of man is too loose and the rule of law is too strict and cautious, enterprises often die as soon as they are in charge and mess as soon as they are released. The boss does not know whether the rule of law is good or the rule of man is good. More people lose prestige, less people lose cohesion. If you rule by law too early, you will be alone; If you rule by man too late, you will lose power. Therefore, it is a difficult process for an enterprise to change from rule by man to rule by law. First, the awareness of the boss, second, the determination of the boss, third, the courage of the boss, and at the same time, the opportunity should be grasped. Only in this way can the enterprise effectively transition from the rule of man to the rule of law, so as to make the enterprise develop healthily!
the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system

bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items< On February 26, 2014, Joe Manchin, a Democratic senator from West Virginia, issued an open letter to a number of regulatory authorities of the US federal government, hoping that relevant institutions would pay attention to the status quo of bitcoin's encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency.
