Blockchain technology in the world
as a blockchain with decentralized concept and distributed shared accounting technology as the core, it will be embedded in many links in the financial field in the future, such as credit enhancement, right confirmation, equity registration, financial trade, digital assets, etc. Blockchain is still in the primary stage of development, whether it is a large institution or a small company, blockchain is still on the road of exploration. As a distributed shared accounting technology, the latest and most cutting-edge technology in the field of financial technology, blockchain, in a greater sense, enables the parties involved to establish a trust relationship at the technical level. At present, this technology has a lot of imagination in the field of equity registration, right confirmation, clearing and settlement in the financial field, as well as in the field of logistics and proct authenticity traceability. Bubi's blockchain points out that at present, more Bubi's technologies are focused on commercial level blockchain technical support services, which specifically includes three areas. First, the field of digital assets includes other digital assets in addition to common points and check-in cards; The second is trade finance; The third is the field of equity, to improve the convenience of equity trading
the development history of blockchain? Blockchain will bring a new revolution in asset ownership in the future“ The first generation of Internet information solved the free transmission of information, but did not solve the problems of decentralization and asset ownership. " This problem can not be underestimated. At the level of capital market, if any technology can clarify the property rights of things that are uncertain, it will be a huge change for the whole market. In addition, blockchain will also lead the great changes in the field of credit enhancement. It is reported that China has about 700 million Internet users“ If every netizen adds tens of thousands of credit lines through blockchain technology, the amount of credit increase will be trillions nationwide, and it can be proved that all your credit is universal in the world at the level of blockchain. " In the future, three things will happen in Internet finance. First, there will be a good matching mode between asset side and liability side; Second, intelligent investment with two main modes of follow-up investment, suggestion and notification; Third, blockchain
"the blockchain model, as a foundation, rather than a business model, will solve a lot of credit problems. The largest blockchain market in the next three to five years should be in China."
Introction to Bubi blockchain
since its establishment, Bubi blockchain has been focusing on the R & D and innovation of blockchain technology and procts, has a number of core technologies, and has made substantial innovation in many aspects, forming a number of core technology achievements, such as: mathematically verifiable distributed consensus technology, fast large-scale ledger access technology, and so on Multi Chain general ledger technology supporting business form expansion, interconnection technology between heterogeneous blockchains, etc. On April 25, "gege integral" introced the integral system into the concept of blockchain, opened up by multiple parties, issued and exchanged integral, and promoted the circulation of integral. All cooperative institutions can jointly participate in transaction verification, account book storage and real-time settlement; The third-party payment platform of the enterprise points issuer makes the points in and out more flexible. Bubi has developed its own basic blockchain 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
has blockchain solved any problems
the most important thing of blockchain is to solve the problem of intermediary credit. In the past, it was difficult for two people who didn't know and trust each other to reach cooperation, and they had to rely on a third party. For example, in the past, there must be a bank or an institution such as Alipay. However, through the blockchain technology, bitcoin is the first time for human beings to complete the transfer behavior that can be trusted by both parties without the participation of any intermediary. This is a major breakthrough in blockchain
the development of blockchain? The history of blockchain development
blockchain technology is the underlying technology of bitcoin. In the early days, not many people paid attention to the underlying technology of bitcoin. However, bitcoin has been running stably for many years without any centralized organization operation and management, and there have been no problems. So many people have noticed that the underlying technology may have a great mechanism, and it can be used not only in bitcoin, but also in many fields. Therefore, bitcoin technology is abstracted, which is called blockchain technology or distributed ledger technology. So from a certain point of view, bitcoin can be regarded as the first application of blockchain, and blockchain is more similar to the underlying technology such as TCP / IP, which will be extended to more and more instries in the future.
2) blockchain, Internet and artificial intelligence should be regarded as technologies of the same height, and blockchain should formally enter our hard science and technology development category
3) pointed out the development and application direction of our blockchain, including the speech that the technology of blockchain has extended to many fields, such as digital finance, Internet of things, intelligent manufacturing, supply chain management, digital asset trading, and so on. In terms of application, there will inevitably be some regulatory or legal problems in the process of application, What are the instructions in this speech? He mentioned that we should implement the rule of law in the management of blockchain, and promote the safe and orderly development of blockchain
4) in the more important point of application and development, it is mentioned that the blockchain is from virtual to real, enabling entity, improving people's livelihood, obtaining instrial advantages, and better serving the development of the whole instrial economy. In fact, through the study of blockchain technology, from one side or the signal released, we express our attitude towards the innovation and leadership of blockchain. We hope that in the development of blockchain, we can first have our own core technology, and we should be a leader in today's fierce international competition
5) it is to enhance the market confidence of the whole blockchain instry, especially for the application and development of the whole blockchain technology. With a great increase in market confidence, it is bound to attract more people in the next period of time, including the capital market and for example, more talents and research applications will enter this field. More capital, more manpower and more other social related aspects, including the rule of law and legislation, will positively promote the application and landing of the whole blockchain technology. These are my four points of view or summary of blockchain technology learning
if you have been concerned about blockchain for a long time, in fact, from the national level, including the 13th five year plan, blockchain technology has been written into the 13th five year plan, which is developed as a parallel technology with artificial intelligence, big data and cloud computing. It has been introced in the second half of 2018, and the office of network information technology has put the blockchain application service on record, From all aspects, it is actually a positive guidance or protection for the development of the whole blockchain
of course, when it comes to blockchain, you may also say that blockchain always thinks of money speculation and so on. In fact, digital currency is only a relatively narrow field in the field of blockchain. We now include support from the mainstream of modern society or the national level, and more support for the application of blockchain technology in the real instry, The core advantage of blockchain technology is decentralization, which can realize point-to-point transaction, coordination and cooperation based on decentralized credit in the distributed system without mutual trust by means of data encryption, timestamp, distributed consensus and economic incentives, so as to solve the common high cost and low cost problems of centralized institutions Low efficiency and data storage insecurity provide solutions
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.
bitcoin:
is an electronic currency proced by open-source P2P software. Digital currency is a kind of network virtual currency. Bitcoin is also paraphrased as "bitcoin."
bitcoin does not rely on specific currency institutions to issue, it is generated through a large number of calculations of specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. Since bitcoin was born with an algorithm, it was stipulated from the beginning that all bitcoins in the world would not exceed 21 million bitcoins. Because bitcoin is not regulated by the government, it is not subject to inflation constraints and external control
people use the computing power of CPU and CpG to "mine" to unlock the new bitcoin. To put it figuratively: bitcoin is equivalent to a gold mine created by people using computers. The setting of this gold mine is limited. The upper limit is 21 million bitcoin. People dig out bitcoin one by one just like miners using the principle of CPU computing
the principle of bitcoin, the distributed characteristics of P2P and the design without central management mechanism ensure that no institution can control the value of bitcoin or create inflation. This decentralization makes it a more secure and value preserving "virtual currency"
But in fact, netizens, as well as traders and investors of bitcoin, do not see one of the biggest drawbacks of bitcoin: bitcoin is not uniqueWhat do you mean? We think that bitcoin is the only one with a cap of 21 million, which seems to have the function of preserving value. But the principle of bitcoin algorithm is not only applicable to "bitcoin", a kind of currency from Japan. Every computer engineer can develop the corresponding algorithm, make a man-made gold mine, and control its upper limit. In this way, every country, every region and every person can develop countless algorithms. Then the market will be full of virtual currencies such as "bitcoin a", "bitcoin B", "bitcoin C", "bitcoin D", and so on. By that time, who are you going to invest in? You can create your own currency
this hidden danger is not a dream. In fact, it has already started. You can log on bitcoin's official website in China. You will find that in addition to bitcoin, there is now another kind of thing called "Yuanbao coin". This is an algorithm similar to bitcoin developed by a Chinese development team. It also has the same upper limit. The same people can't control it and dig Yuanbao coin out through "mining"
if they can do this, I believe many computer workers can also write their own "Yuan Bao coin", "gold and silver coin", "China bitcoin" and "Shanghai bitcoin". Bitcoin, as the first code to appear, has no credit support from the Central Bank of any country. It has value only because of the scarcity of 21 million. In fact, this scarcity does not exist, because everyone can develop the virtual currency code, and then people from all over the world can mine it. So what's the price of bitcoin? There are limited kinds of metals on earth, so each metal has different value according to its quantity and scarcity. But the bitcoin like code in the network world is infinite. As long as people are willing, they can create unlimited kinds of bitcoin code. Tell me, is bitcoin still valuable
blockchain Technology:
the main function of blockchain is to store information. Any information that needs to be saved can be written to or read from the blockchain, so it is a database
the essence of blockchain is to achieve the goal of decentralization and disintermediation through a new generation of data technology, so as to transmit value more transparently and efficiently. This kind of point-to-point verification will proce a new network "basic protocol" which is different from TCP / IP in the Internet era
blockchain shows us a world in which all assets will be digitized. In a valuable Internet, the transfer of assets will be as fast, convenient and cheap as the transmission of information today
the significance of blockchain is not the wealth of digital currency, but the value transmission of its technology itself. Therefore, Ma Yun has repeatedly separated blockchain from digital currency, and stressed that the extent to which blockchain technology will change the world is beyond people's imagination
difference:
blockchain is a technology, based on blockchain technology, there can be many applications
bitcoin: is one of the most popular and well-known applications
the content is for reference only, only represents personal views, and does not make any suggestions
the definition of blockchain
in a narrow sense, blockchain is a kind of chained data structure that combines data blocks in a sequential way according to the time sequence, and it is a distributed account book that can not be tampered with and forged by means of cryptography
broadly speaking, blockchain technology uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, and uses cryptography to ensure the security of data transmission and access It is a new distributed infrastructure and computing method to program and operate data by using intelligent contract composed of automated script code
there are many channels to learn blockchain
① you can buy some books related to blockchain, learn some knowledge related to blockchain, take notes in your spare time, and consult relevant information
② watch some videos of blockchain on the Internet, the contents of which are easy to understand, with relevant examples, It's also a very good way to learn
③ you can take part in some offline blockchain learning exchange meetings, or take part in some training courses, and some teachers will answer questions for you
to sum up,
all roads lead to Rome. There are many channels to learn blockchain, and the best one is suitable for you
of course, blockchain has also been applied in real life, such as medical equipment corresponding to Ruitai coin, ant financial services, etc.
In fact, as of August last year, Bank of America had filed at least 30 patent applications for blockchain technology, while in February last year alone, they filed nine applications with the U.S. patent and Trademark Office
