500 year top innovation of blockchain

1. Hello, it's a great honor to be here to answer your question. The following are some of my views on this issue. If there are any mistakes, please point them out. 1. The so-called blockchain technology, also known as the distributed ledger technology, is an Internet database technology, which is characterized by decentralization, openness and transparency, so that everyone can participate in database records
2. Blockchain is an innovative application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies in the Internet era. In recent years, the development and application of blockchain is of great significance to technological innovation and instrial revolution. This experience introces the relevant knowledge of blockchain technology
3. Blockchain is a distributed ledger, which can contain financial and / or non-financial transactions. It can be replicated (distributed) on multiple systems in almost real time through peer-to-peer network. Each participant "owns" the same ledger and gets updated when adding any transaction. Each participant helps to determine the inherent "invariance" of all existing records, Using cryptography and digital signature to prove identity, authenticity and enforce read / write access, there is a mechanism that makes it difficult to change history, and it is easy to detect someone trying to change it. Thank you very much for your patience. If you have any help, please accept it. I wish you a happy life! thank you!

2. IBM, Microsoft, Oracle, Accenture, Tencent, Alibaba, Jingdong, network, etc. have all done it. Many large banks, including Ping An Bank, have also launched their own blockchain solution platforms or solutions. However, it should be added that large companies do not mean strong technical strength, because blockchain is still in the hot stage of concept in the world. Unicorn blockchain companies are likely to emerge in the future, such as EOS in foreign countries and honeycomb chain of Fanrong technology in China. The efficiency of TPS and packing into blocks may be much higher than that of large companies.

3.

Because the blockchain technology is not mature at this stage, and the infrastructure is not perfect, many applications are limited, and the overall application is still in a very early stage

First of all, 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. Secondly, anyone can set up a server and join the blockchain network to become a node. In the world of blockchain, there is no central node (decentralization). Every node is equal and keeps the whole database. You can write / read data to any node, because all nodes will be synchronized in the end to ensure the consistency of the blockchain

5. What can blockchain do? Blockchain, a great technology with the birth of bitcoin, can greatly rece transaction costs and improve efficiency in the financial field, which is enough to make Wall Street excited. However, this is only the tip of the iceberg, and its potential application prospects are very wide, which will subvert all aspects of our lives in the future

blockchain is an important concept of bitcoin. In essence, it is a decentralized database, as well as the underlying technology of bitcoin. One of the most basic characteristics of bitcoin is decentralization. In recent months, financial giants have graally begun to pay attention to the technology of bitcoin, and used it in non monetary fields, such as stock trading, election voting and so on 1) Art instry
artists can use blockchain technology to declare ownership, issue works that can be numbered and limited edition, and can target any type of art in digital form. It even includes a trading market where artists can buy and sell through their websites without any intermediary services
(2) the real estate instry
uses blockchain technology to solve various problems faced by everyone when participating in real estate, including naming process, land registration, agency and so on
(3) the insurance instry
the financial instry has always been the most sensitive to advanced technology. Traditional banking and securities giants have been investing in blockchain venture capital since 2014, with a total global investment of US $1 billion in two years
(4) P2P wallet
personal assets can be traded through this P2P wallet in the future without going through any central organization, such as bitcoin

most blockchains are in their infancy, and most of them are overseas. There are very few good blockchain projects in China, so it is not recommended that any non professionals invest in blockchain projects. If you are very interested in blockchain technology and have technical or financial background, it is suggested to consider starting a business in this area. In terms of protocol system of blockchain, the bottom layer is the underlying technology of blockchain, including the technical protocol of blockchain, as well as some platform routing and basic algorithms; In the middle layer, we need to solve the problems of some application interfaces and the issuance and verification of some certificates, including the services of some instry platforms, big data analysis, etc. This is a rough division, and there should be more detailed division; The top is some applications of blockchain, including financial applications and other applications, Internet of things and so on

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

the simple understanding of blockchain is a technology at the bottom of bitcoin, which is also a point-to-point e-cash system, which can realize point-to-point value express. We should distinguish the concepts of bitcoin, bitcoin blockchain, blockchain and blockchain technology. In the countries with more developed finance in the past, the technology of Finance and block has a long history, and the legislation of digital currency and block chain network is also very important. With the advent of the financial era, large financial institutions are studying blockchain technology. They have their own team and concept technology. Graally, regional banks are also participating in the discussion of digital currency. In addition to the application and support of this technology, blockchain has great influence on enterprises. For larger domestic enterprises, Bubi block is also applied to all kinds of equity In the fields of supply chain and points, domestic financial institutions and enterprises have focused on the value of new instries and developed their own blockchain platforms. Blockchain has instantly become a new domestic innovation instry. Overseas, compared with China, the United States has already obtained 15 blockchain patents at the end of last year. The application of blockchain finance is entering a new stage in an all-round way. Various applications will be more and more in-depth, and the relevant changes will attract more and more attention, which will also form a great new trend

financial institutions have launched blockchain technology into a new era of Internet and big data applications, which has laid a pattern from negative interest rate profit driven innovation to technological innovation. At this time, domestic giants have suggested that the cooperation alliance not only affects the implementation of financial infrastructure, but also is an important means to expand business cooperation. In terms of implementation, the future payment system securities deposit will not only affect the implementation of financial infrastructure, It is inseparable from the financial and settlement system and big data analysis, while the domestic giants join hands and propose a mutually beneficial cooperation mode, which can not only effectively improve operational efficiency, but also rece costs and find new growth points, After the adoption of blockchain technology, whether the company's procts and services can proce a new business model or a cost advantage far lower than that of competitors

what can blockchain do? What about blockchain? Although at present, there is no mature underlying blockchain technology platform solution, technical problems such as capacity scalability, privacy protection, non net settlement and non recourse need to be solved, and large-scale application of blockchain technology also needs to reset it architecture and reengineer business process, these are only technical problems. The real test of blockchain technology rooted and growing in the financial field is the regulatory agencies and financial institutions. Will the inherent "de supervision" and "de centralization" characteristics of blockchain make the market players have no power to drive technological innovation. However, because the blockchain is a technology based on mathematical algorithm, the establishment of trust relationship between all parties does not need the help of intermediaries or authority centers, and the cost of establishing trust relationship is almost zero (on the premise of the establishment of blockchain financial infrastructure and ancillary infrastructure), and the blockchain code is open-source, no geographical restrictions, and the network pattern is distributed and interconnected, It lays a technical foundation for the establishment and development of Inclusive Finance and shared finance in the future, and creates material conditions for the integration and unification of global finance. From this point of view alone, blockchain technology is bound to establish a core position in the future financial development, and rely on and complement each other with finance, and win-win in the future.

7. Yimai cloud bar, they are integrated into the cloud service at the end of the blockchain, and will add the characteristics of flexible architecture and fast deployment. The business that can only be launched in the past half a year may now be launched in half a month or so. Time and economic costs have been greatly saved, and the "cloud" of enterprise data and business has become faster and more economical.

8. The main problems are the lack of core technology, the scarcity of blockchain talents, the imperfection of instry laws and regulations, the lack of instry cognition and so on. But now there are more blockchain policy support, and these problems are graally improving. Blockchain applications are also constantly landing. Changsha high tech Zone has officially launched a blockchain project, which is called SMIC blockchain service platform, It is a government enterprise service platform, cooperating with Bank of Changsha, Dean justice, etc., and now it is the stage of collecting enterprises on the chain.
