On November 1, 2008, a person who called himself Satoshi Nakamoto posted a research statement on a secret cryptography review group, stating his new idea of electronic currency bitcoin came out, and the first transaction of bitcoin was completed. Bitcoin has got rid of the constraints of third-party institutions with the help of information technology, which Nakamoto calls "regional chain". Users are willing to dedicate the computing power of CPU and run a special software to be a "digger", which will form a network to maintain the "regional chain". In the process, they also generate new money. Trading also extends on this network. The computer running this software can solve the problem of irreversible code, which contains several trading data. The first miner to deal with the problem will get a 50 bitcoin reward, and the relevant trading area will join the chain. As the number of "miners" increases, the difficulty of each puzzle also increases, which keeps the proctivity of bitcoin in each trading area at about 10 minutes
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
according to foreign media reports, computer scientist Ted Nelson released a video on the Internet on Sunday saying that he had determined that the founder of bitcoin was Shinichi Mochizuki, a professor of mathematics at Kyoto University. The founder of bitcoin has always used the pseudonym of Satoshi Nakamoto, and there has been a lot of speculation about its true identity in the Internet field. Nelson released a video saying that he has determined that wangyuexinyi is the real founder of bitcoin
in 2013, Wangyue Xinyi became famous for proving ABC conjecture. He attended Philip Exeter college in high school, one of the most prestigious high schools in the United States, and graated just two years later. Wangyue Xinyi entered Princeton University at the age of 16, left school as a doctor at the age of 22, and became a full professor at the age of 33. It is extremely rare in the academic world to obtain the title of full professor at such a young age. This mathematical superstar may have solved one of the most important problems in the field
Mr Nakamoto has left few personal data on the Internet, especially in recent years, he has almost disappeared, so his life experience has become a mystery. On March 7, 2014, when the news that Dorian P. Nakamoto, the founder of bitcoin, was found came out, it quickly became the most attractive news on the Internet
different from the outside speculation that it may be a fictional name, "Nakamoto" is a real name. He is a 64 year old Japanese American who likes to collect train models. He used to work in large enterprises and the U.S. military and engaged in confidential work. In the past 40 years, Nakamoto has never used his real name in his life. According to a 1973 Los Angeles District Court file, when he graated from Caltech at the age of 23, he changed his name to Dorian prentice Satoshi Nakamoto. From then on, he no longer used the name "cong", but used Dorians Nakamoto as his signature
11. No voice in the world is louder than silence. If one can understand your silence, he will never misunderstand your language
12. Be sure to make yourself excellent, both physically and internally. At the same time, tell yourself, I change well, not to meet the right person; But let others know: it's not single that chooses me, but I choose to be single
13. I don't want to run today, so I go running. This is the way of thinking of long distance runners
14. Don't be depressed. Life is like an electrocardiogram. Plain sailing proves that you are dead
15. Before everything gets better, we always have to go through some unhappy days, which may be very long or just wake up. Sometimes, it takes courage to choose happiness
16. Before everything gets better, we always have to go through some unhappy days, which may be very long or just wake up. Sometimes, it takes courage to choose happiness
17. In life, there should be something to do and something not to do. Life is a kind of pursuit and continuation. Life is an endless relay race. Don't regret when you are alive, just like you can't let yesterday come back. Thank you for yesterday. All kinds of yesterday are experiences. Experience is not about success and failure, experience is not worth it or not
18. Occasionally I want to be alone without any interruption. I just want to empty myself and feel the beauty of life
19. All the surprises and good luck in the world are your accumulated character and kindness
20. More and more clear four words: human words are formidable. But more to understand the five words: people say what to fear
21. Life will get better when it is bad to a certain extent, because it can't be worse. After working hard, I know a lot of things. I stick to it and come here.
the core problem of blockchain solution is not "digital currency", but how to establish a "trust" ecosystem to meet the occurrence and development of economic activities under the environment of information asymmetry and uncertainty. This problem is called "Byzantine general problem", or "Byzantine fault tolerance" or "two armed forces problem". It is a difficult problem in the process of information machine interaction in a distributed system, that is, when any node in the whole network can't trust its counterpart, How to create a consensus basis for secure information interaction without worrying about data tampering
blockchain uses algorithmic proof mechanism to ensure the security of the whole network. With it, all nodes in the whole system can exchange data automatically and safely in a de trusted environment. For details of Byzantine Generals, please refer to relevant papers
the second meaning of blockchain is to realize transnational value transfer. At the beginning of the birth of the Internet, the core problem to be solved is information manufacturing and transmission. We can quickly generate and information to every corner of the world with network through the Internet, but it still can not solve the value transfer and credit transfer. The so-called value transfer here means that everyone in the network can recognize and confirm the way to transfer a certain part of the value accurately from one address to another, and it must be ensured that after the value transfer, the original address reces the transferred part, while the new address increases the transferred value. The value mentioned here can be monetary assets, some physical assets or virtual assets (including securities, financial derivatives, etc.). And the results of this operation must be recognized by all parties, and the results can not be manipulated by any party
in the current Internet, there are various financial systems, and there are many payment systems provided by banks or third parties, but it still relies on centralized solutions. The so-called centralized solution is to place all the value transfer calculations in a central server (cluster) through a certain company as endorsement. Although all the calculations are automatically completed by the program, the centralized person or organization must be trusted. In fact, to solve this problem through centralized credit endorsement can only limit credit to certain institutions, regions or countries. From this we can see that the fundamental problem that must be solved is credit. Therefore, the core issue of value transfer is transnational credit consensus. In such a complex global system, it is very difficult to establish a global credit consensus system out of thin air. Due to the different political, economic and cultural situations of each country, it is almost impossible to achieve complete mutual trust between enterprises and governments of the two countries, which means that whether the endorsement is made with the credit of indivials or enterprises or governments, Even if the value exchange between countries can be completed, it also has huge time and economic costs. But in the long history of mankind, no matter how different the religion, politics and culture of each country is, the only thing that can reach a consensus is mathematics (Basic Science). Therefore, it is no exaggeration to say that mathematics (algorithm) is the greatest common divisor of global civilization, and it is also the basis for human beings to obtain the most consensus. If we take the mathematical algorithm (program) as an endorsement, all the rules are built on an open and transparent mathematical algorithm (program), so that all people with different political and cultural backgrounds can reach a consensus
future development? The Internet will make the global interaction more and more close, accompanied by a huge trust gap. At present, the existing mainstream database technology architecture is private and centralized, which can never solve the problem of value transfer and mutual trust. Therefore, blockchain technology is likely to become the next generation of database architecture. Through decentralization technology, we will be able to complete the great progress of mathematical (algorithm) endorsement and global mutual trust on the basis of big data
As a specific distributed data access technology, blockchain technology participates in data calculation and recording through multiple nodes in the network, and verifies the validity of their information (anti-counterfeiting). From this point, blockchain technology is also a specific database technology. The Internet has just entered the era of big data, but at present, big data is still in a very basic stage. But when we enter the stage of blockchain database, we will enter the era of real big data with strong trust endorsement. All the data in this is of indestructible quality, and no one has the ability or need to question it. Perhaps we are now at a major turning point - the early stage of a major turning point that is almost the same as the profound changes brought about by the instrial revolution. It's not just the exponential, digital and combinatorial progress and change of new technologies, but more surprises may be ahead of us. In the next 24 months, the planet will grow more computing power and record more data than all stages of history combined. In the past 24 months, this value-added may have exceeded 1000 times. These digital data information is still growing faster than Moore's law
blockchain technology will not only be applied in the field of financial payment, but will be extended to all the current applications, such as decentralized microblog, wechat, search, rental, and even taxi software. Because blockchain will allow human beings to conct large-scale cooperation in a way of no geographical restrictions and no trust
Bubi blockchain uses cryptography provable algorithm to build multi center network trust, which is open, transparent, tamper proof and revocable; Multi party participation in information transparent sharing, the establishment of authentic traceability chain path, direct to consumers
our generation is likely to be lucky to experience two of the most amazing events in human history. All people and all machines on the earth have launched unprecedented large-scale collaboration with unprecedented mutual trust through blockchain technology. Secondly, based on this, real artificial intelligence will be created. These two times will profoundly change the economic development mode of the world. Entrepreneurs, entrepreneurs, scientists and all kinds of geeks will use this abundant world to create something that can shock and delight us
unlike all 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 about 21 million.
