Summary of blockchain Technology
Publish: 2021-05-17 04:10:06
1. The following points are the characteristics of the blockchain summarized by jinwowo group:
1 - Decentralization: because the blockchain relies on each node to achieve system maintenance and ensure the authenticity of information transmission, it is based on distributed data storage without centralized management by a certain center, Therefore, the attack and tampering of a node will not affect the healthy operation of the whole network
2-DE Trust: the establishment of a connection between any two nodes does not need to trust each other's identity, and the data exchange between the two sides does not need the basis of mutual trust. Since all nodes in the network can act as "supervisors", there is no need to worry about fraud
3 - extensible: blockchain is an underlying open source technology, on which various kinds of extension, decentralized and distrusted applications can be realized<
4 - anonymization: the two sides of data exchange can be anonymous, and the nodes in the network can exchange data without knowing each other's identity and personal information
5 - Security and reliability: because the activities between any nodes are supervised by the whole network, and the database adopts distributed storage, for hackers, first, they can't disguise and cheat, Second, we can't control the network only by conquering a node.

2. Blockchain has the following characteristics:
decentralization. Blockchain technology does not rely on additional third-party management institutions or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes information self verification, transmission and management through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain
openness. Blockchain technology is based on open source. In addition to the private information of all parties involved in the transaction is encrypted, the data of blockchain is open to everyone. Anyone can query blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent
independence. Based on consensus specifications and Protocols (similar to various mathematical algorithms such as hash algorithm used by bitcoin), the whole blockchain system does not rely on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention

3. I have summarized the following two characteristics:
1. Block chain technology is a decentralized consensus mechanism to maintain a complete, distributed and tamper proof ledger database. It can enable the participants in the blockchain to achieve a unified ledger system without establishing a trust relationship. 2. Renren blockchain technology service platform does not need to develop one click to create its own blockchain system to quickly build blockchain infrastructure; One click to complete the development and deployment of blockchain applications; To provide your customers with open, transparent and credible services.

4. The application of blockchain technology in life has just started, but the changes it brings are very huge. This kind of change comes from all aspects, and will have an important impact on our ordinary people's lives
"now the college entrance examination is a lifetime, but if we use the form of blockchain, we can record all the learning records and extracurricular activities of a child from the age of six to the college entrance examination. So the examiners of the college entrance examination don't need to pass an exam or an interview to decide the selection of talents. They can decide what kind of talents they want through all their records. "
about the application of blockchain technology, Qin Yi, partner of Deloitte global financial services, said when introcing it to Jinping media
as for blockchain, more explanations in China still stay at the conceptual level, and there is no really large-scale popular application in China, so we have to say that blockchain still keeps a certain distance from the public. In this interview, I believe it can help you have a deeper understanding of blockchain
blockchain is disintermediation
blockchain, and many explanations are decentralization. Different from the general explanation. "It's not decentralization, it's disintermediation," says Qin
because data is distributed in a distributed way, there is a strong security mechanism in it. Qin Yi said: "because no matter which server is serving, the entire data storage is not easy to detect. But most importantly, because of the reliability of the data, we don't need an intermediary to prove who you are, but rely on a record that we can trust each other to promote any transaction in our life
in her opinion, blockchain is actually a database, but when storing data, it has its own characteristics, such as security, integrity, authenticity, non tamperability, etc
for this technology, Qin Yi concluded: such technology will bring earth shaking changes to life
how to embody the commercial value
compared with foreign blockchain technology, domestic blockchain technology is still in a stage of popularization and cognition. What kind of business value will the future blockchain bring us? Looking at the progress abroad, maybe you can see some possibilities
"two weeks ago (on April 20), Bank of Ireland and Deloitte jointly issued a statement. Three months ago, Ireland's International Investment Banking Department asked Deloitte to help design and track the investment behavior of its clients. Strengthen the understanding of customers. In order to meet the regulatory requirements of Europe, they have successfully completed the validation model through the efforts of the past three months. "
a Deloitte executive also said that if this technology can be applied, it will greatly rece the transaction costs of the instry
Deloitte also published a report in 2016, saying that 2016 will be the first year for blockchain to move from laboratory to real life. Bubi (Beijing) Network Technology Co., Ltd. (hereinafter referred to as Bubi) is a leading blockchain technology service provider in China. Since its establishment, Bubi has been focusing on the R & D and innovation of blockchain technology and procts. It has a number of core technologies, and has made substantial innovation in many aspects, forming a number of core technology achievements, such as mathematically proven distributed consensus technology, distributed consensus technology, and so on Fast large-scale account book access technology, multi chain general ledger technology supporting business form expansion, interconnection technology between heterogeneous blockchains, etc. We have developed our own blockchain basic service platform, which has been applied in equity, supply chain, credit and other fields. Bubi has been committed to building an open value circulation network with the core of decentralized (polycentric) trust, so that digital assets can flow freely
with the in-depth development of many companies, the effect of blockchain technology on the life of ordinary people is becoming more and more obvious.

5. Blockchain technology has a lot of applications in finance, and many characteristics make the future of the financial instry have a lot of imagination
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.
