Long clip bitcoin

1.

Babbitt is an app focusing on blockchain information, not a brand. He is committed to providing users with content information reading and data services. It mainly includes market, information, express and community services

Liu Zhipeng, founder and CEO of Babbitt, is also a researcher of blockchain theory and proposer of the idea of "Impossible Triangle" of blockchain. Changjia is the early preacher of bitcoin, and also the founder of the famous blockchain media Babbitt and the famous public chain Biyuan

Babbitt is a new application mode of blockchain distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. As a decentralized database and the underlying technology of bitcoin, blockchain uses cryptographic methods to generate data blocks. Each data block contains information of a batch of bitcoin network transactions, which is used to verify the effectiveness of its information (anti-counterfeiting) and generate the next block

extended data:

Babbitt was founded in 2011. As one of the earliest blockchain companies in China, with the purpose of popularizing blockchain technology and disseminating blockchain concept, Babbitt, chainnode, matpool and other proct lines have been formed, and developed into a collection of information, community, data, information, information, information, information, etc Business incubation and blockchain technology landing in one of the blockchain comprehensive service platform. In 2019, Babbitt was selected into the "Hangzhou Unicorn & amp; List of quasi Unicorn enterprises

Babbitt runs on different forms of heterogeneous digital assets and atomic assets (including warrants, equity, dividends, bonds, intelligence information, forecast information, etc.) on the original blockchain, which can be registered, exchanged, bet, and more complex interaction and cooperation based on the contract

Babbitt's mission is to connect the bit world and the atomic world, and build a decentralized network for the registration and circulation of diversified assets. The goal of Biyuan chain is to become the world's largest dedicated public chain platform and explore the combination of different types of assets and blockchain

2. [crazy bitcoin, what is it
on January 3, 2009, the first bitcoin was born
bitcoin is a kind of virtual currency proced by open-source P2P technology software. This concept was first proposed by Satoshi Nakamoto (or pseudonym) in 2009. Bitcoin currency system is independent, and its operation does not depend on the support or credit guarantee of central bank, government, large enterprises
at the beginning of its birth, bitcoin was just a geek's toy. Now it is the fastest growing virtual currency
in the past, US $1 = 1300 bitcoins. Now, US $1 = more than US $200. Its value has increased nearly 300000 times
on the 10th of this month, the exchange rate of bitcoin against the US dollar hit a new high of 263, then dropped sharply to US $63 the next day, and now it has returned to the level of US $120. No roller coaster is more exciting than the trajectory of bitcoin's exchange rate against the US dollar over the past ten days
the total amount of bitcoin money graally increased according to the designed rate, and the increase rate graally slowed down, and finally reached the limit of 21 million in 2140. The decentralized design structure of bitcoin ensures that theoretically, no institution can control the total amount of bitcoin or create inflation. In other words, there are only 21 million bitcoins
according to the estimation of the number of simultaneous online transactions of bitcoin, the United States, Germany and Russia are the most widely used countries of bitcoin, which is related to the choice of monetary policy of the three countries
for example, from 2000 to 2013, e to the volatile monetary policy of the Russian central bank, Russia's inflation rate rebounded every few years and is still at a high level of 7%. The continued quantitative easing by the Federal Reserve and the long-standing opposition to the European Central Bank in Germany are all related to the popularity of bitcoin in these countries. In addition, these three countries have relatively advanced computer science level, and have more advantages in accepting and applying bitcoin< In an interview with China business daily, horserider, the moderator of bitcoin English Community Chinese edition, said that he does not think bitcoin is a perfect currency, but can sweep away the uncertainty brought about by monetary policy through strict mathematical logic. On the one hand, the emergence of bitcoin can enrich the variety of currencies, on the other hand, it may also be an impact for countries whose monetary policy is not serious enough

[what are the ways to get bitcoin
first of all, users can buy bitcoin in bitcoin trading markets such as mt.gox. At present, most countries in the world have online or offline markets where they can buy bitcoin with their sovereign currencies
secondly, users can obtain bitcoin by solving the mathematical problems in the transaction information package data block, which is similar to the process of looking for gold in the real world, so it is called mining, and the bitcoin obtained by users is paid as the "capital" for processing transaction information

[who is holding bitcoin?]
although the core developers of bitcoin have repeatedly emphasized that bitcoin is only an "experimental" project and repeatedly pointed out the risks of investing in bitcoin, this has obviously not dampened the enthusiasm of bitcoin enthusiasts
Chang Jia (pseudonym) is one of the most influential science fiction writers of the new generation in China. In an interview with our reporter, he described the intimate contact with bitcoin as a journey of "science fiction into reality"
from 2010 to 2012, Changjia purchased 2000 bitcoins in succession. He also recently sold ten of his science fiction collections in the bitcoin market at 0.07btc (about 35 yuan), which sold for 23.3 yuan at Jingdong Mall. He also plans to promote this practice to other science fiction writers, because he thinks it is convenient, fast and very safe
it seems that long clip only uses bitcoin as another common electronic currency (for example, q-coin), but in fact, like his partner horserider, his enthusiasm comes from his admiration for the idea that mathematical logic can build a fairer currency world, and bitcoin is just practicing this idea, although the results of this "experiment" are unpredictable for the time being
in June 2011, horserider accidentally saw an article about bitcoin in Google Reader's subscription, "at that time, I fell in love with bitcoin at first sight. In the evening, I began to buy bitcoin, and suggested that my friends also start to buy bitcoin." Horserider, who had been a PE fund manager for two years, described this in an interview with our reporter
it may be a professional relationship. Unlike long clip, horserider doesn't have much bitcoin cash, but holds more bitcoin denominated equity“ The company I invested in is mainly engaged in mining (bitcoin) and server promotion. At present, the P / E ratio is only about 1 or 2 times. Every week and every month, I will receive a certain amount of dividends, but the amount is not much. " Nevertheless, he is very confident in the future earnings of these stocks
in addition, the winklevos brothers used to be one of the "big players" of bitcoin, claiming that they own 1% of the total bitcoin mined
the brothers founded a social networking site called connectu and recruited Mark Zuckerberg. After Zuckerberg left to create Facebook, the brothers sued him, accusing Zuckerberg of stealing their ideas. The case ended with the winclavors brothers receiving $20 million in cash compensation and shares in Facebook

[is it a "Ponzi scheme"
although the developers and users of bitcoin take it seriously, from the very beginning, there has been a controversy around whether bitcoin is a "Ponzi scheme", but in theory, this "accusation" is not tenable< The securities and Exchange Commission (SEC) defines "Ponzi scheme" as "using the funds of new investors to pay for the early investors". In many Ponzi schemes, the initiators usually promise high-yield and low-risk investment to new investors, but in fact, the initiators only ince new investors to enter in order to pay income to early investors and use it for their own consumption, but rarely make real investment
in October 2012, the European Central Bank issued a report called "virtual currency schemes", which pointed out that, at least in theory, bitcoin is not close to the SEC's definition of "Ponzi scheme"
although the saying that "if the holder of bitcoin wants to cash it out, new users are willing to buy bitcoin" sounds like a "Ponzi scheme", there is no organization in the bitcoin community that can control the users' money and then disappear with it
in fact, users of bitcoin trade spontaneously in the community, and there are almost no intermediaries, and no one can directly benefit from the growing number of bitcoin holders
however, the recent drastic exchange rate fluctuation between bitcoin and the US dollar seems to indicate the beginning of a new value feast. No speculators are willing to be absent. Does it mean that the speculative value of bitcoin far exceeds its use value
horserider told our reporter that although many investors try to arbitrage through the exchange rate fluctuation of bitcoin, this is not the purpose of bitcoin design. Bitcoin itself is just a payment system“ Until now, speculation is still only the third level theme in the bitcoin English community. More community members are concerned about the improvement of payment agreement, the development of application software and the popularization of trade. "< However, horserider does not deny the significance of speculators. He believes that speculators are the lubricant of economic activities. The prosperity of American railway network and the rapid penetration of Internet technology are closely related to speculators

[is bitcoin suitable for donation< According to Huo Qingchuan, director of cooperation and Development Department of one foundation, one foundation has received a total of 65 bitcoin donations, with a market price of about 50000 yuan. This is the first time bitcoin has become a donation in China

bitcoin donation is not as simple as expected. China's law stipulates that no one is allowed to operate the transaction between RMB and virtual currency without a special license. But for those "farmers" who are diligent in digging money, their willingness to donate is enough

welcome to discuss~

3. Based on the experience of nearly ten books, I would like to briefly recommend: blockchain from digital currency to credit society, written by Changjia and Han Feng; Technical guide for blockchain, written by Zou Jun et al; Blockchain technology driven Finance: Translated by Lin Hua and Wang Yong. Forget the rest. I want to see the author / (ㄒ o ㄒ) / ~ ~.

4. Picking medicine: you can get it by learning medical skills at level 4 (ranking behind the diagnosis and treatment card, so you still need to learn at level 4. If you continue to learn, you can get the raw medicine, cold medicine and strong medicine)
Mining: you can get the mining tasks automatically when the blacksmith is working (Meinong, Beiqian, Beibei, etc.) Xiangmo town of Izu Three Kingdoms)
then move on the big map (there will be corresponding options near the original landing City, but not on the road and stronghold)
attachment: collecting herbs Mining site
Mining: the place like a canyon between Hino city and Qingzhou City (about 5.5 mining per day)
Mining: between Yitian city and Shanchuan city (about 4 mining per day)

5. What is blockchain technology? The understanding of people in each instry is different, and the relevant explanations are graally emerging because of more and more practical applications. With the popularity of this blockchain technology, the relevant achievements are also growing. If we want to understand this kind of technology, we must have a deep understanding from the reality

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.

6. In fact, the threat of quantum computers to bitcoin is not mining, but trading attacks. We know that the transaction of bitcoin is completed by decentralized cryptography authentication, and the core of this authentication method is hash algorithm. If there is a quantum computer, it can create collisions (Grover algorithm, polynomial acceleration) to forge transactions for profit. Because the core algorithm of bitcoin has been fixed, if the algorithm is not changed, the key length cannot be increased, and this attack cannot be resisted. However, if there is a practical quantum computer, what can we do is better than this kind of attack...

Virtual currency is a hot topic in recent years, and many people have made a lot of money because of it, but the current situation of these people is so sad

some people become famous and realize the freedom of wealth, while some people continue to speculate like gamblers and lose everything

03: besides three sides and three kinds of regret, I know another one that is more interesting

this kind of people all heard that other people made money from it, and then they regretted very much. Why didn't they buy a few bitcoins in those years

then, in order to make up for this regret, these people are crazy, looking for this coin and that coin every day, spending all their savings, but in the end, few of them increase their prices

you should know that scarcity is the most important thing. Now all kinds of virtual currencies have been saturated for a long time. What's the use of joining in this? If you don't say anything else, just bitcoin, a lot of people can't do it, OK

10. As a book, because it is a collective creation similar to "crowdfunding", the logical relationship and organization between the chapters are not very harmonious, some of the contents are repetitive and even have different opinions, which also shows from the side that even within the bitcoin circle, people's understanding is not completely consistent. However, it can not erase the great value of bitcoin as a social experiment. As for bitcoin itself, this book has made it very clear. If you are not a commercial speculator like me and are interested in bitcoin technology and the social impact behind it, it is enough to remember two sentences: computing is power; Money is information. Bitcoin itself can grow into a mature virtual currency. I don't care about it very much, and I don't agree with everyone rushing to grab bitcoin like Xiaomi. There is a very long process from the emergence of a new technology to its maturity. Even if the experiment of bitcoin will fail, in my opinion, virtual currencies similar to or better than bitcoin will reappear in the future. The economic function of bitcoin (or virtual currency that may replace bitcoin in the future) and a series of network changes it brings will truly open a new era of Internet economy and drive social changes. In the past, I didn't understand Amway, which doesn't write science fiction, but has been selling bitcoin everywhere. But when you really understand bitcoin, maybe every geek will feel that participating in bitcoin is really creating the future There are all these important books, maybe not enough. Incidentally, the first science fiction about bitcoin was published in new science fiction on November 2013, and Chen GE's a toss of heaven and earth still has some improvements as a novel, but it describes the author's own understanding of bitcoin more accurately, The future of science fiction will be waiting for us.) of course, people who support bitcoin think that it is right to abandon dirty politics and entrust human beings to pure numbers. To some extent, it is also too optimistic, even without considering the development of technology itself.
