The invention of digital currency
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 InternetRuitai currency: it is a digital currency designed with the participation of Sha Qian, a well-known digital currency scholar in China. It is an asset certificate, and credit endorsement is a medical equipment asset and part of the shares of Sha Qian Tong
Yuanbao coin: it was developed by Yuanbao team in China. Yuanbao coin is a relatively successful currency in China, and many related projects have been carried out
Qianjin card: developed by Qianfeng team in China, it is mainly used in Qianfeng mall and overseas luxury purchasing market.
the first country to recognize bitcoin as legal was Germany, which first defined bitcoin as an alternative currency. Of course, in the future, sovereign digital currencies may be popular, and digital cryptocurrencies such as bitcoin, Ruitai coin, Laite coin and vitality coin will become a supplement.
digital currency is a new technology, which is different from the traditional electronic payment tools used by online banking and third-party payment companies. It is developed on the basis of a series of new technologies - they are not tools to transmit money; They are money in themselves. Among them, digital currency based on cryptography is also called cryptocurrency. Bitcoin is a model of this kind of digital currency. After its birth, it inspired many similar systems. Some commercial banks and central banks have also begun to develop their own digital currency. According to the different issuers, we can divide digital currency into three types:
1. Digital currency issued by non-financial institutions
in November 2008, a man named Nakamoto Tsung invented a new technology called blockchain and designed a point-to-point e-cash system, namely bitcoin, for the first time. On January 3, 2009, Nakamoto completed the code development of bitcoin. Due to its point-to-point and electronic nature, bitcoin can be passed directly between two people without the need for a centralized settlement institution. Therefore, it is a fast, low-cost, borderless payment system
2. Digital currency issued by commercial banks
some large international financial institutions have taken a fancy to the low-cost, fast and safe characteristics of digital currency, and began to try to use its underlying technology, namely blockchain technology, to develop their own digital currency. For example, four of the world's largest banks, UBS, Deutsche Bank, Santander bank and New York Mellon bank, are already involved. Their digital currencies are similar to those mentioned above, but their issuers are different. It is particularly noteworthy that financial institutions develop digital currency to meet the needs of their own rapid clearing transactions, rather than challenge the financial situation by replacing the legal currency issued by the central bank. The domestic Puyin group also launched Puyin
3. Digital currency issued by the central bank
some central banks, such as the people's Bank of China and the Bank of England, also plan to launch their own central bank digital currency after some research on digital currency. Technically, CBDC is the same as the above two, but e to its special identity, CBDC will have a greater economic impact, which is the reason why the central bank wants to introce CBDC.
in the case of hanging order transaction, the transaction will be made according to the price you give (if it can be done), and if the real-time price is the best, the real-time price will be used.
Nakamoto invented bitcoin
on November 1, 2008, a person who called himself Nakamoto Tsung published the white paper bitcoin: a peer-to-peer e-cash system on the P2P foundation website, stating his new idea of e-money bitcoin came out
in 2009, Nakamoto designed a digital currency, namely bitcoin. The booming bitcoin market has gone up and down, and the identity of its founder "Nakamoto" has always been a mystery. Rumors about "the father of bitcoin" involve from the US National Security Agency to financial experts, and also give bitcoin a mysterious aura
extended data:
starting from the essence of bitcoin, the essence of bitcoin is actually the special solution generated by a bunch of complex algorithms. A special solution is one of the finite solutions of a system of equations. Every particular solution can solve the equation and is unique
in the metaphor of banknotes, bitcoin is the number of the top word of a banknote. If you know the number of the top word on a banknote, you have the banknote
and the process of mining is to constantly seek the special solutions of the equations through huge amount of calculation. The equations are designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million
