Blockchain application service refers to
A: first, application of blockchain
blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies
Second, blockchain technology1, financial field
blockchain has great potential application value in international exchange, letter of credit, equity registration, stock exchange and other financial fields
Internet of things and logistics
blockchain can also be naturally combined in the field of Internet of things and logistics
2, public service
blockchain is closely related to people's proction and life in public management, energy, transportation and other fields, but the centralization of these fields also brings some problems, which can be transformed by blockchain
3. In the field of digital right,
through blockchain technology, works can be authenticated to prove the existence of text, video, audio and other works and ensure the authenticity and uniqueness of ownership. After the works are confirmed on the blockchain, the subsequent transactions will be recorded in real time to realize the full life cycle management of digital rights, and can also be used as a technical guarantee in judicial evidence collection
4. In the field of insurance
in terms of insurance claims, insurance institutions are responsible for fund collection, investment and claims settlement, and often have higher management and operation costs
5. The data stored on the public domain
blockchain is highly reliable and tamperable, which is naturally suitable for social public welfare scenarios
according to Xiao Wang, the concept of blockchain as a service (baas) is mainly proposed by Microsoft and IBM. To put it bluntly, it is actually a new type of cloud service, a cloud service combined with blockchain technology. For example, Microsoft's azure cloud computing platform and IBM's bluemix garage cloud platform all provide blockchain as a service baas
blockchain as a service (baas) is a space created by enterprises such as Microsoft and IBM from their own cloud service network to run a blockchain node. Compared with ordinary nodes and exchange nodes, the main purpose of baas nodes is to quickly establish the development environment they need, and provide a series of operation services based on blockchain, such as search query, transaction submission, data analysis, etc. these services can be centralized or decentralized to help developers verify their concepts and models faster. The service of baas node is reflected in: stronger tool, easy to create, deploy, run and monitor blockchain..
Blockchain instry has great growth potential, and five aspects promote the healthy development of Technology Virtual reality and other technologies are another emerging technology that will have a significant impact on the future, which is expected to promote human beings from the era of information internet to the era of value Internet
some countries and regions in the United States, Japan and the European Union have promoted the development of blockchain as an important national development strategy, and vigorously promoted the development and application of blockchain technology. China also attaches great importance to the technological innovation and instrial development of blockchain.

3. Support entrepreneurship and innovation in the field of blockchain
encourage cross-border integration between blockchain enterprises and user units, guide instry organizations to establish public service platforms, support third-party organizations to carry out evaluation and detection of blockchain services, promote rich instrial applications of blockchain, and serve the transformation and upgrading of the real economy
4. Actively build and improve the blockchain standard system
accelerate the development and application of key standards, and graally build a perfect standard system. Actively connect with ITU, ISO and other international standards organizations, substantially participate in more international standardization work, and actively contribute more "Chinese power"
5. Accelerate the improvement of the policy environment for blockchain development
support qualified enterprises to carry out application innovation and mode innovation, and guide and encourage enterprises, universities and scientific research institutes to jointly cultivate professional talents needed for blockchain development. Support eligible blockchain enterprises to enjoy the preferential tax policies of the state to support the development of software instry and small and medium-sized enterprises
the instrial scale is small, but the growth potential is huge
the blockchain economy is on the eve of the outbreak period. The financial instry is relatively widely used, and the application of other instries has also entered the stage of exploration and development. It is estimated that from 2017 to 2022, the direct market value of blockchain will increase from US $410 million to US $7.68 billion, with a compound annual growth rate of 79.6%. It is estimated that all kinds of extended business based on blockchain will reach US $100 billion in 2020
instry application areas continue to expand
the financial instry takes the lead in the application of blockchain technology, and many financial applications have been implemented; Medical instry is an important area of blockchain application, which can better protect privacy, improve service quality and management efficiency; The demand of social authentication for blockchain is rising rapidly to solve the proof problem caused by information asymmetry; The application of blockchain technology in communication, supply chain and other fields is expanding rapidly
I have seen your question. In which aspects can blockchain be applied? Below by the small series to answer for you
in this case, a better technology stack is recommended: pingcap / tidb, or distributed database based on pbft protocol, rather than private blockchain system. Therefore, the blockchain technology service is called batsthe Xueshuo innovation blockchain Technology Workstation of Lianqiao ecation online is the only approved "blockchain Technology Specialty" pilot workstation of "smart learning workshop 2020 Xueshuo innovation workstation" launched by the school planning, construction and development center of the Ministry of ecation of China. Based on providing diversified growth paths for students, the professional station promotes the reform of the training mode of the combination of professional degree research, proction, learning and research, and constructs the applied and compound talent training system.
but if we have to compare them, we can first see the differences or connections between the two characteristics
the traditional server is centralized
take a look at the figure below, it is a typical centralized network, the most central is the server, the others are clients, the server is responsible for providing services to all clients, and the client obtains services from the server, such as downloading files.
1. Blockchain plus supply chain finance nowadays, the supply chain of most commodities, from providing raw materials to manufacturing finished procts, will involve several upstream and downstream small and medium-sized enterprises; And these enterprises are facing the pressure of unlocking supply chain working capital. Supply chain finance means that banks and other financial institutions make systematic financing arrangements for all member enterprises of the supply chain, so as to form a win-win situation between the core buyer enterprise and the supplier: the buyer optimizes the working capital, and the supplier generates additional operating cash flow, so as to minimize the risk of the whole supply chain. The traditional supply chain finance has three pain points: 1. Information can not be shared, low efficiency, poor credibility; 2. The circulation of bills is inconvenient, the settlement of contracts is slow, and there are often capital risks; 3. Credit cannot be transferred and financing is difficult. Blockchain can achieve the following functions: 1. Core enterprises, multi-level suppliers and financial institutions share transaction data, a / R and a / P data and protect business privacy; 2. The circulation of enterprise creditor's rights, automatic settlement of funds, and acceleration of enterprise payment and repayment; 3. The payment commitment of core enterprises is transferred between multi-level suppliers and financial institutions to transfer the credit of core enterprises
2. Blockchain traceability in the field of commodity traceability, the combination of blockchain and Internet of things technology can trace the whole process of commodity circulation, so as to avoid illegal vendors making use of the information asymmetry in the commodity chain to proce fake and shoddy goods. To prevent some participants from tampering with data or falsely claiming the loss of information when it is not concive to their own situation, resulting in the difficulty of proof and accountability. In addition, blockchain traceability can break through the information islands in different links of the supply chain and improve the cooperation efficiency of the supply chain
3. Blockchain helps the blockchain technology of medical services to open up many links, such as hospital prescription, pharmacist prescription review, drug distribution, drug payment, process supervision, etc. Through the distributed storage of blockchain and the accurate matching of information on the chain with patients, we can ensure the one-time dispensing effectiveness of prescriptions, eliminate prescription modification or abuse, and facilitate supervision. In the future, patient information, prescription information and drug circulation information can be encrypted and desensitized through blockchain technology, which can open up more medical application scenarios
4. The integration of blockchain and IOT instrial Internet at the 5th World Internet Conference, the supet instrial Internet platform, which integrates the Internet of things and blockchain technology, was selected as the world's leading Internet technology achievements and became the only award-winning instrial Internet platform
in addition, blockchain data sharing, blockchain judicial chain, blockchain charity, trusted digital content right services, etc. In such instries as government, finance, instry and logistics, health care, retail and Internet, block has a wide range of business application scenarios.
