Follow up development of blockchain Technology
1. Germination stage: the real germination stage of blockchain was from 2007 to 2009. In 2008, a Japanese American with the pseudonym of Nakamoto first expounded a new fantasy report on electronic money in the form of a synonym on the cryptography discussion group, and bitcoin came out. As early as 2007, Nakamoto began to explore a series of new technologies to create a new currency. On October 31, 2008, bitcoin white paper was released, and on January 3, 2009, bitcoin system officially began to operate
the main technologies supporting bitcoin system include hash function, distributed ledger, blockchain and asymmetric encryption; It can be seen that these technologies build the initial version of the blockchain, and it can also be said that the blockchain is the underlying technology of bitcoin. During the three years from 2007 to 2009, bitcoin was an experimental stage in which a very small number of people participated, and the real commercial activities had not really started
2. "Geek" niche stage: here, "geek" refers to people who are crazy about Internet technology and take technological innovation as fashion and life. On February 6, 2010, the first exchange of bitcoin appeared. On May 22 of the same year, someone bought two hamburgers with 10000 bitcoins. On July 17 of the same year, the exchange Mt. GOx was established, marking the official inflow of bitcoin into the market. Nevertheless, the only people who can really understand and enter the market to participate in bitcoin trading are geeks who are keen on Internet technology. They discuss bitcoin technology on the forum, mine for bitcoin on their own computers, and then buy and sell bitcoin on Mt. GOx. Now these geeks have become billionaires
3. Market brewing stage: the price of bitcoin was $13 at the beginning of 2013, but on March 18 of the same year, the government of Cyprus closed the bank and stock market e to the financial crisis, which made the price of bitcoin soar, and the highest price rose to $266 in April. On August 20 of the same year, the German government confirmed the currency status of bitcoin. On October 14, China network announced the opening of bitcoin payment channel. In November, the US Senate hearing also confirmed the legitimacy of bitcoin. On November 19, the price of bitcoin rose to US $1242, forming a new high. Nevertheless, the foundation for blockchain to enter the mainstream social economy is not yet available, and the soaring price of bitcoin is only e to over optimistic expectations. The containment of China's banking system, the collapse of Mt. GOx and other events made the price of bitcoin continue to fall. At the beginning of 2015, the price of bitcoin has dropped below $200. From 2013 to the beginning of 2015, the public began to understand bitcoin and blockchain
4. The mainstream period of blockchain: on June 23, 2016, the United Kingdom left the European Union, the fifth nuclear test of North Korea in September, Trump's election in November and other events, the uncertainty of the world's mainstream economy led to the recovery of bitcoin with the function of risk aversion. The market demand was large, and the increase of trading volume made the price of bitcoin soar from $400 in 2016 to $20000 in 2017, The wealth effect of bitcoin and the transaction overflow caused by network congestion of bitcoin have led to the outbreak of other series of virtual currencies, as well as a variety of blockchain applications, resulting in the emergence of a large number of blockchain assets that are 100 times, even 1000 times and 10000 times, which has aroused the crazy pursuit of the world, Subsequently, the Chicago Mercantile Exchange launched bitcoin futures trading, marking that bitcoin has officially entered the mainstream investment proct series, and bitcoin and blockchain have entered the global attention
5. Instry landing stage: after the market frenzy in 2017, the virtual currency and blockchain have been adjusted in terms of market, supervision, cognition, etc. in 2018, returning to rationality. In 2017, many blockchain projects that follow the blockchain technology will graally die out with the cooling of the market, and the projects with real blockchain applications will be initially implemented. 2018 is not only the first year of the blockchain, but also a gold rush period for the blockchain. After the waves wash away the sand, what remains is relatively good gold
from the perspective of the history of blockchain development, blockchain technology is not yet mature and is currently in the growth period. The specific practical application of blockchain is only used in the financial field. It still needs a long way to go to apply blockchain from other instries. However, we should grasp the trend of blockchain and actively learn from the new field of blockchain.
in the Internet era, there is a database behind every system. This database can be regarded as a large account book. In the past, the person who maintained the system was responsible for managing the database and recording the user's behavior, that is, bookkeeping. However, the blockchain is "decentralized", which allows every member of the system to participate in it, not only everyone bookkeeping, but also through links, Everyone can have a complete account book
"blockchain is essentially a collective recording mode. What's special is that it adopts a set of techniques in an ingenious way to realize the authenticity and credibility of the recorded results, which is difficult to destroy and tamper with. " Zhang Xiaorong said, "first, everyone has the right to record and authenticate with each other to distinguish the true from the false, which is called consensus mechanism; Second, no one can tamper with the records, because there are cryptographic signatures; Third, everyone has a , so even if some account books are damaged, the whole will not be affected. This is called distributed storage. The information recorded in this way is presented in block mode according to the time chain, so it is called blockchain. "
various cryptocurrencies represented by bitcoin are originally an application of blockchain technology, which can be described as blockchain version 1.0. However, around 2014, the instry began to realize the important value of blockchain technology. Blockchain graally separated from digital currency and applied to various economic and social fields other than digital currency
it has broad application prospects
blockchain technology is considered as a disruptive innovation after steam engine, electric power and Internet. If the steam engine and electricity liberate the proctivity, and the Internet has changed the way of information transmission, the blockchain, as a machine for building trust, may change the way of value transmission
for example, in the financial field, the cost of reconciliation, clearing and settlement between financial institutions, especially cross-border financial institutions, has always been very high, and there are complex manual processes. The application of blockchain technology can help rece the cost of reconciliation and dispute resolution between financial institutions, and significantly improve the processing speed and efficiency of payment business, It also makes small cross-border payments possible. In December 2017, China Merchants Bank completed the RMB position transfer business from Hongkong Wing Lung Bank to Shenzhen Branch of Wing Lung Bank. This is the world's first interbank cross-border RMB clearing business based on blockchain technology
in addition, according to the white paper 2016 on China's blockchain technology and application development issued by the Ministry of instry and information technology of China, the application of blockchain has been extended to medical and health, ecation, charity, social management and other fields. Taking the cultural instry as an example, the low cost of reproction, the high cost of safeguarding rights, and the difficulty of providing evidence make the protection of intellectual property rights a pain point for the instry. With blockchain, the proction, dissemination and transaction records of cultural procts are true, transparent and reliable, and the problem can be solved
Zhang Xiaorong said that blockchain technology has solved two major problems in the era of Digital Economy: one is the visible flow direction, and the other is zero trust cost. In the past, the circulation of physical paper money was invisible, but the flow of all digital assets had a "chain" to check. Yang Yanchao, a researcher at the intellectual property center of the Chinese Academy of Social Sciences, also believes that the biggest advantage of blockchain is that it has truly completed the credit construction in an anonymous society, bringing new opportunities to many fields, thus making various innovative applications possible
there is a long way to go in the future development
in terms of technology promotion, there is no big barrier to blockchain, which has been confirmed in the global practice of bitcoin, and its main resistance comes from the obstacles in concept and implementation
"on the one hand, the society may be very concerned about the" naked "state in the blockchain. Blockchain has built a "Skynet" for the commercial society. The company's economic activities are all recorded, so there is no secret to speak of. In this way, some business strategies may not be implemented under the blockchain. "
"on the other hand, the current legal system lags behind the development of information technology, so how to put the emerging blockchain technology under the legal supervision needs to be studied." Duan Yongchao said
the core of blockchain is decentralization, which will have an impact on the long-standing central management model. In addition to the law, how to establish a regulatory environment that can promote the application of blockchain technology, so that the technology can benefit the society and not be used to do evil, is also an urgent problem to be solved.
By the end of 2019, the number of blockchain research institutions in China has reached 97. In addition, domestic colleges and universities have arranged blockchain technology research, strengthened theoretical knowledge innovation of blockchain technology, and improved their blockchain technology R & D capability. By the end of 2019, there are 24 colleges and universities in China participating in strengthening blockchain technology R & D. The core technologies are mainly distributed in consensus algorithm, cross chain, underlying architecture and multi chain
in 2020, the blockchain instry will be further standardized
in 2020, China's blockchain policy will continue to be favorable, the standards and specifications will be more perfect, the instrial scale will continue to grow, the technology will continue to innovate and develop, and the application demonstration effect in key fields will accelerate. At the same time, according to the problems existing in the development of China's blockchain in 2019, CCID blockchain Research Institute puts forward six suggestions: accelerating the formulation of top-level design, establishing and improving the regulatory system, accelerating the innovation and development of core technologies, promoting the third-party evaluation and certification, strengthening the cultivation of professional talents, and accelerating the implementation of applications in various fields
- the above data comes from the analysis report of China's blockchain instry market outlook and investment strategic planning of foresight Instry Research Institute
Renren blockchain technology services
blockchain has the ability to innovate trade, transaction and business processes
the two basic concepts supporting blockchain are "business network" and "account book" -- it is thanks to these two concepts that blockchain can become a wise and unchangeable way of trade, transaction and business process execution
network members exchange various assets through an account book that can be accessed by all members. When the network synchronizes the account book, all members need to confirm the transaction of tangible or intangible assets. This shared view helps to establish legitimacy and transparency, even when the parties are not familiar with each other
blockchain can improve visibility and trust in business
by providing visibility to all participants, blockchain can rece transaction settlement time from days or weeks to seconds. The technology can also eliminate the intermediate third party that is usually needed to verify transactions in the past, so as to rece the excessive cost
because blockchain is built on the concept of trust, it can help enterprises rece the risk of illegal behavior on the payment network, thus helping to rece fraud and cyber crime
speed, cost, efficiency and transparency are the most important advantages of blockchain within enterprises and in the company ecosystem where trade activities are carried out. It is precisely because of such advantages that far sighted enterprises are more looking forward to using blockchain technology to innovate infrastructure and better carry out business
the value of blockchain development lies in the growth of the ecosystem
as a business network, blockchain can accommodate a variety of different types of participants. According to the number of participants in the blockchain network, the value of the assets exchanged, and the need to authorize members with different credentials, the adopters of blockchain technology should pay attention to the differences between "licensed" and "unlicensed" blockchain networks
when these business networks continue to expand, the real value of blockchain will be realized. With a strong ecosystem, business networks can reach critical scale more easily, enabling users to build new business models and innovate transaction processes.
for a single (domestic) central bank, bitcoin can be regarded as a "foreign exchange currency", and bitcoin will not be affected by the central bank's monetary policy. From this perspective, bitcoin is bound to bring about the so-called currency competition. When American tourists travel abroad, they will encounter the experience of exchanging foreign currency with unofficial exchange rate. The original intention of local people to exchange dollars may be to avoid the impact of high inflation (inflation tax)
if this kind of exchange can be "carried forward and widely used", the government's way of using inflation tax to increase fiscal revenue will be limited, and the traditional foreign exchange control will lose considerable effect. As long as there is Internet or telephone, people can use digital currency as the exchange medium<
challenge global currency status
although bitcoin is unlikely to replace the world's major currencies in the short term, bitcoin still has the opportunity to play a leading role in some specific occasions. The status of US dollar is obvious in many countries in the world, but the liabilities created by foreign banks under US dollar denominated deposits have brought jurisdiction problems. If the Bank of America further provides bitcoin denominated loans and accepts the redemption of bitcoin, what should the regulatory authorities do? In fact, there are similar signs in the euro dollar market today
in other words, at a time of financial crisis, if the market wants bitcoin deposits instead of US dollar deposits, then the central bank's status as "lender of last resort" in the traditional sense will be completely lost
acting as a safe haven asset
a safe haven asset does not mean a risk-free asset, but refers to the asset that investors are willing to pour in at a time of crisis. In the 1970s, real estate was a safe haven asset; In the 21st century, American debt has become a safe haven asset. Can bitcoin become the next key safe haven asset? The answer may be yes or no. But looking back on the dominant position of CUF in Hungary's mortgage loans in the time of the euro zone crisis, bitcoin obviously has a chance to become famous in the first World War: under the background of dollar inflation and bitcoin deflation, the US dollar / bitcoin exchange rate will plummet because the US Federal Reserve can't expand the supply of bitcoin
play the role of securities
in a perfect macroeconomic model, securities trading should be seamless. However, under the influence of monetary policy, the liquidity of OTC transactions of bonds is very poor. Even the ten-year US bonds with the best liquidity have had liquidity problems. Demand for good quality collateral, usually treasury bonds, has soared. If blockchain technology is mature enough, it is likely to bring billions of dollars of collateral supply to the market. Of course, lower demand for treasury bonds may lead to higher interest rates
maintain the stability of financial market
there is a view that the use of blockchain will lead to the withdrawal of global central banks from the stage of history. This possibility naturally exists, but in the short term, it is not too realistic - the central bank needs a lot of hard assets, such as real estate and human capital, to find liquidity carriers / media to completely retreat from the background
there is also a view that blockchain technology will make the financial market completely transparent, thus bringing a more robust financial system. However, it should be pointed out that the mainstream diamond and davige bank squeeze model does not rely on the opacity of the financial market. In theory, the bank's portfolio is completely transparent. But even so, unexpected large-scale redemptions can still cause problems in the financial system
the central bank's digital currency / cash
the current currency and payment structure were formed before the birth of the Internet. The world has changed dramatically, so people must learn to adapt. There is no reason to refuse the possibility of central banks providing digital currency. Before bitcoin, the U.S. Treasury provided online digital bond accounts. Although this kind of account is not used for payment system, it can be applied in theory
the digital account of the central bank has many advantages. First, depositors no longer need deposit insurance because there is no default risk in the central bank; Second, money managers who hold a lot of money can choose the central bank account as overnight deposit instead of shadow banking; Third, the cost of paper money supply will be completely eliminated; Fourth, it will be very convenient for the central bank to pay depositors' interest to facilitate the transmission of the central bank's monetary policy
practical application
Bubi blockchain has made a number of breakthroughs in the technical platform, which can meet the scenario of tens of millions of users, and has the ability to quickly build the upper application business. Bubi blockchain has been applied in equity, supply chain, points and other fields, and is concting experiments and application tests with exchanges and banks. As an integral application on Bubi blockchain platform, Shubei Hebao has been launched recently. Sunshine insurance, as the first large financial institution in China, issues blockchain integral (yangguangbei) on this platform, which is a good example for the landing application of blockchain technology in various instries
blockchain technology will have a profound impact on the financial instry and have an important impact in a long time. People will witness the profound changes in reality one by one.
