What book is bitcoin
The earliest is a kind of network virtual currency. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals. In 2013, the U.S. government recognized the legal status of bitcoin, making the price of bitcoin soar
< H2 > extended information:bitcoin is e-cash similar to e-mail. Both parties need "bitcoin wallet" similar to e-mail and "bitcoin address" similar to e-mail address. Just like sending and receiving e-mail, the remitter pays bitcoin directly to the other party through a computer or smart phone according to the recipient's address
starting from the essence of bitcoin, the essence of bitcoin is actually a special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique
many websites for technology players have begun to accept bitcoin transactions. Websites such as mtgox and btcchina, as well as some Taobao stores, can even accept services such as bitcoin exchange for us dollars and euro. There is no doubt that bitcoin has become a real currency in circulation, rather than a virtual currency like Tencent Q coin
Dahua blockchain is a book published by Tsinghua University Press in September 2019, written by Zhang Yingping. This book is a blockchain book that comprehensively explains bitcoin, Ethereum, super ledger and EOS, a blockchain development guide from engineer basic skills, development language to smart contract development, and a blockchain engineer guide from technology, project to career development planning
"Dahua blockchain"
"Dahua blockchain" is a blockchain book that pays equal attention to theory and practice, easy to understand and professional.

Through learning, every reader can master the development of blockchain
the future of bitcoin is still uncertain, so it is recommended that you do not set foot in it easily.
de dollarization
de dollarization: the revolution against the dollar and the risk of a new financial world order.
at present, China's economic and social credit environment is still relatively weak, and the credit cost is relatively high. Blockchain technology proposes a set of low-cost "trust" solutions to rece the credit cost of the whole society, which is of great significance to promote the development of China's credit economy. Although this technological innovation in the field of Internet finance is still immature, many big banks in the world have been competing to invest resources in research and development, which should attract the attention of China's banking instry and regulatory authorities
(1) commercial banks should do a good job in technology and talent reserve, and actively participate in the formulation of international standards
in order to guard against the risk of digital currency, China's commercial banks are unable to trade digital currency at present, and the research on technological innovation behind digital currency is lagging behind, which is slightly asymmetric with the upsurge of private research and development on blockchain in China. Nowadays, the development of blockchain technology, P2P and other emerging modes of disintermediation is graally moving from concept to application driven by the joint innovation of global large financial institutions. China's major banks should also pay close attention to the latest innovation trends of international peers, join the ranks of research and development of blockchain procts as soon as possible, and adjust their development strategies in a timely manner, Adapt to the new situation of Internet finance business operation mode. One is to set up R & D laboratories or cooperate with financial technology companies. In addition to the development of different blockchain application scenarios, it can also be combined with Inclusive Finance according to the national conditions, such as studying how to use blockchain technology to achieve low-cost fund transfer payment in economically underdeveloped areas and improve the financial services in these areas. Second, we should actively participate in the formulation of international standard agreements, strive for the right to speak, and avoid being a passive follower
(2) regulatory agencies also need to continue to pay attention to the development of the latest Internet technology and be prepared for it
first, "decentralization" brought by blockchain technology does not mean that centralized organizations are not needed in economic operation. Blockchain technology hopes to break the privilege and human manipulation, and let computer algorithm realize "credit free Notarization". But from the perspective of practice, theoretical dection can not be completely mapped to real life. For example, e to the lack of regulation, digital currency transactions such as bitcoin face high risks of speculation and money laundering. Therefore, if blockchain technology wants to become a new channel of capital circulation, it needs to have the standards of supervision and implementation to protect the interests of all parties in the market. In this regard, the regulatory authorities should formulate relevant standards and norms, especially operational norms, to ensure the rational use of financial innovation procts with strong power; At the same time, we should improve the protection of consumers' rights and interests, strengthen the ecation of financial consumer rights and interests protection, and improve consumers' awareness of risk prevention. In short, even in the "decentralized" business system, it also needs to be standardized and guaranteed by the centralized departments
secondly, the regulatory authorities should be prepared to deal with the possible changes in regulatory methods. At present, new technology has a profound impact on the monetary system of various countries, and the traditional policy framework and means of regulating economy and finance are increasingly unable to keep up with the changes of the situation. Regulatory authorities should keep pace with the times, make full use of the convenience of financial technology to improve the way of supervision and improve the means of supervision. For example, in the future, if securities lending, repurchase and margin trading can all be traded through transparent and open blockchain, the regulatory authorities can consider using the information of the public ledger to monitor the systemic risk in the market, which is not only efficient but also reliable
thirdly, regulators can actively embrace the new technology of Internet finance. As for the financial structure changed by technology, the central bank can have two kinds of reactions: monitoring and responding to the progress or taking the initiative. Kara Stein, a member of the US Securities Regulatory Commission, believes that regulators need to be in a leading position, make use of the advantages of blockchain technology and quickly respond to its potential weaknesses. The Bank of England's research further indicates that the central bank can consider issuing digital currency based on blockchain in the future, and if properly operated, it can increase financial stability
blockchain was first introced to support the formation and circulation of bitcoin, and has been recognized by people. However, different from the controversial bitcoin, the launch of blockchain technology adapts to the new era of Internet development, such as mobile Internet, Internet of everything, and Internet at any time. A large number of online transactions are in urgent need of party identity verification and transaction confirmation, greatly improving the efficiency of transaction settlement and clearing, and ensuring the security of capital and information, Blockchain technology has been paid more and more attention and attracted more and more people to explore, innovate and apply
by the end of 2015, more than 20 top financial institutions in the world have begun to explore the application of blockchain technology in finance. More and more people believe that the blockchain technology is to use the new encryption authentication technology and decentralized mechanism to maintain a complete distributed and tamper proof continuous ledger database, so that the participants in the blockchain can ensure the security of funds and information through a unified ledger system without mutual recognition and trust. This is of great significance to financial institutions and financial innovation
first, blockchain technology can rece trust risk
blockchain technology has the characteristics of open source and transparency, and system participants can know the operation rules of the system. Under the blockchain technology, because each data node can verify the authenticity and integrity of the account book content and account book construction history, to ensure that the transaction history is reliable and has not been tampered with, which is equivalent to improving the accountability of the system and recing the trust risk of the system
Second, from the perspective of enterprises, Bubi blockchain has been applied to equity, supply chain, points and other fields, and is concting experiments and application tests with exchanges and banks. Bubi blockchain focuses on the innovation of blockchain technology and procts, has a number of core technologies, and has developed its own blockchain service platform. Moreover, many blockchain innovation and entrepreneurship enterprises continue to emerge
thirdly, blockchain can drive the birth of new business models
the characteristics of blockchain technology enable it to achieve some business models that are difficult to achieve in the centralized mode. For example, in the Internet of things instry, some organizations have proposed to use blockchain technology to manage the identity, payment and maintenance tasks of tens of billions of Internet of things devices. Using blockchain technology, IOT equipment manufacturers can greatly extend the life cycle of procts and rece the cost of IOT maintenance
fourthly, blockchain technology has a flexible architecture
according to different application scenarios and user needs, blockchain technology can be divided into public chain, private chain and alliance chain, which can be selected according to the actual use of institutions
fifthly, blockchain technology is a favorable tool for sharing finance
the essence of sharing finance is to achieve the optimal allocation of financial resources by recing the asymmetry of financial information, and to ensure the implementation of the rights and interests of both parties through strict third-party authentication and supervision mechanism, so as to facilitate the transaction. Through the use of blockchain technology, financial information and financial value can be more strictly protected, and more efficient and lower cost flow can be realized, so as to realize the sharing of value and information
sixth, the openness of blockchain technology encourages innovation and collaboration
through the opening and cooperation of source code, blockchain technology can promote the cooperation among different developers, researchers and institutions, and learn from each other, so as to achieve a more efficient and secure solution. In recent years, many overseas financial institutions and commercial institutions have tried to use blockchain technology to improve their business model. In China, although this technology has not been widely recognized and applied, it has begun to attract more and more attention, and its influence is rapidly increasing. Now blockchain technology has been regarded as one of the basic protocols of the next generation of global credit authentication and value Internet, and the importance of blockchain technology to China's financial instry and financial system can not be ignored
of course, we must know that the development of blockchain technology is still at an early stage in the world, and various technical solutions, application scenarios and business models need to be further explored and improved. Especially in China, as a new concept and theory, people's cognition, research and practice of blockchain have just started. In order to overtake, catch up with and lead the world in this field, we need enough attention and more investment. It needs the active investment and positive interaction of theoretical researchers, network technologists, financial practitioners and regulatory authorities, Have the courage to explore and innovate
what is blockchain technology? People will know more and more about this technology, and play a more and more important role in reality, and are supported by many organizations, so that the popularization of blockchain in reality will enter a new application stage.
