Who maintains and upgrades bitcoin

1.

The concept of bitcoin was founded by Nakamoto

On December 12, 2010, when bitcoin graally became a hot topic, he quietly left and disappeared from the Internet

As a descendant of samurai, Nakamoto was born in 1949 in Beppu, Japan. His mother, quanzi, was a Buddhist and brought him up in poverty

When his parents divorced in 1959, Nakamoto's mother remarried and immigrated to California with her three sons. Nakamoto and his stepfather don't get along well, but according to his younger brother Arthur, Nakamoto showed his talent in mathematics and science when he was very young, but also showed his "fickle and strange interest"

Nakamoto graated from Caltech, majoring in physics. Upon graation, he joined Hughes Aircraft and worked in defense and electronic communications. Later, Nakamoto worked for the U.S. military, and his experience was classified as a state secret. Now searching his files, his life is a blank

In 2008, in an e-mail group discussing information encryption on the Internet, he published an article outlining the basic framework of the bitcoin system. In 2009, he established an open source project for the system, officially announcing the birth of bitcoin. On December 12, 2010, when bitcoin graally became the climate, he quietly left and disappeared from the Internet

2. Bitcoin is a digital currency with a total amount of 21 million. Like the Internet, bitcoin has the characteristics of decentralization, globalization and anonymity. It is low-cost and has no restrictions. It's not said who controls bitcoin, not even the developers. In terms of operation, bitcoin is actually a decentralized account book on the Internet. Bitcoin network is jointly controlled by global bitcoin users. No one or organization can change or stop the operation of bitcoin unless the vast majority of bitcoin users agree to make a change (such as rule modification or version upgrade). In the bitcoin system, you can really control your money, not through banks. For the first time in human history, bitcoin has used technical means to ensure the sanctity of private property

(the above opinions are all from the Internet)

3. 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
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
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
from 12:00 noon on January 24, 2017, China's three major bitcoin platforms officially began to collect transaction fees
hope to adopt

4. Hanging order is the number of orders waiting to be bought and sold behind the five trading prices transmitted from the exchange ring the market trading period. Together with five trading prices, these ten data constitute the most original public data in the whole trading system

5. Bitcoin is a distributed account book. There is no core server. As long as there are records in six blocks, the transaction records and accounts are legal
uniqueness is that your account is unique. Each user has only a portion of all user account records
those less than 1 bitcoin can also be traded. There is a bitcoin exchange and you can exchange them with any existing currency
the account is anonymous, just a string of codes
the essence of money is a credit certificate. You can understand it as an IOU. Bitcoin itself is not money, but because of its concealment and decentralization, it can act as a credit certificate for cross-border settlement, avoid the supervision of various rights, and facilitate money laundering. Therefore, bitcoin becomes money.

6. Bitcoin is a system that needs the support of many computers. This is how the system is designed. There are only so many coins. As time goes on, less and less coins can be found. Graphics cards are used for mining. In fact, we use a group of numbers to test. If the result is correct, it will be "currency". If the result is incorrect, it will be counted (similar to x-ticket). It's faster to calculate with graphics card than with CPU, so it's better to mine with graphics card
it is people who maintain the platform and want to make money. In fact, bitcoin has no meaning. It is just a string of numbers. It consumes resources and has no value. It is "speculation"—— Someone can buy it.

7. Bitcoin is a digital currency with a total amount of 21 million. Like the Internet, it has the characteristics of decentralization, globalization, anonymity and so on. Transferring bitcoin to the other end of the earth is as simple as sending e-mail. It's very convenient for me to use on the haobtc platform

8. Bitcoin has two kinds of names: broad sense bitcoin and narrow sense bitcoin. Generally speaking, bitcoin refers to broad sense bitcoin. Before August 1, 2016, bitcoin was a complete bitcoin. Now it has been divided into three coins, including bitcoin (SV), bitcoin (core) and bitcoin (cash). Therefore, the broad sense of bitcoin refers to the combination of these three currencies. In a narrow sense, bitcoin refers to the core, because in the process of bifurcation, the price is temporarily the highest, so it inherits the name of the old bitcoin. In the process of future development, who can win is the real bitcoin. At present, the development path of bitcoin (SV) is most in line with the vision of bitcoin.
