⑻ What fields can blockchain be applied to?
Financial applications: Blockchain has inherent advantages in the financial field. On the Internet, this is the genetic decision of blockchain. of.
(1) Insurance business: With the development of blockchain technology, in the future, personal health status, accident records and other information may be uploaded to the blockchain, allowing insurance companies to be more timely and accurate when customers apply for insurance. Accurately obtain risk information to reduce underwriting costs and improve efficiency. The shared and transparent characteristics of the blockchain reduce information asymmetry and the risk of adverse selection; while its historical traceability characteristics are conducive to reducing moral hazard, thereby reducing the difficulty and cost of insurance management.
(2) Asset securitization: The pain point of business in this field is that the authenticity of the underlying assets cannot be guaranteed; there are many participants and many operating links, and transactions are transparentProblems such as information asymmetry occur when the degree of risk is low, making it difficult to control risks. The pain point of data lies in the low efficiency of transfers between participants, the clearing and reconciliation of funds between parties’ trading systems often requires a lot of manpower and material resources, and there are multiple online and offline channels for asset repayment, making it impossible to monitor the true status of assets, and there are still assets After the package is formed, the trust of all parties in the transaction chain in the authenticity and accuracy of the underlying asset data is an issue.
(3) Digital bills: The pain points in this field lie in three risk issues. Operational risk, due to the centralization of the system, once the central server has a problem, the entire market will be paralyzed; market risk, according to statistics, in 2016, there were seven risk events involving hundreds of millions of dollars, involving multiple banks; moral hazard , there are incidents such as "one ticket selling more" and false commercial bills in the market. Blockchain's disintermediation, system stability, consensus mechanism, and non-tampering characteristics reduce operational risks, market risks, and moral hazards in traditional centralized systems (4) Cross-border payments: The pain point in this field is the long payment cycle , high fees and low transaction transparency. The third-party payment company is the center to complete the accounting, settlement and liquidation in the payment process, and the payment cycle is long. For example, the payment cycle for cross-border payments is more than three days, and the cost is high. The blockchain is deintermediated, the transactions are open, transparent and cannot be tampered with. There is no third-party payment institution to join, which shortens the payment cycle, reduces fees and increases transaction transparency.
(5) Credit management: The pain points in this field are the lack of data sharing, the asymmetry of information between credit agencies and users; the formal market-oriented data collection channels are limited, and the battle for data sources consumes a lot of costs; the problem of data privacy protection is prominent , the traditional technical architecture is difficult to meet new requirements, etc. In the field of credit reporting, blockchain has the characteristics of decentralization, trustlessness, timestamps, asymmetric encryption and smart contracts. At the technical level, it ensures that limited and controllable credit can be achieved on the basis of effectively protecting data privacy. Data sharing and verification.
(6) Supply chain finance: The pain points in this field are the long financing cycle and high costs. Centered on the core enterprise system of the supply chain, it is difficult for third-party credit enhancement institutions to authenticate the authenticity of various relevant vouchers in the supply chain, resulting in long manual review times and high financing costs. The blockchain's deintermediation, consensus mechanism, and non-tampering characteristics eliminate the need for third-party credit enhancement agencies to verify the authenticity of various relevant certificates in the supply chain, reducing financing costs and shortening the financing cycle.
(7) Asset securitization: The business pain point in this field lies in the fact that the authenticity of the underlying assets cannot be guaranteed; there are many participating entities, multiple operating links, low transaction transparency, and information asymmetry, making it difficult to control risks. The pain point of data lies in the low efficiency of transfers between participants, the clearing and reconciliation of funds between parties’ trading systems often requires a lot of manpower and material resources, and there are multiple online and offline channels for asset repayment, making it impossible to monitor the true status of assets, and there are still assets After the package is formed, the trust of all parties in the transaction chain in the authenticity and accuracy of the underlying asset data is an issue. Blockchain disintermediation,The consensus mechanism and non-tampering characteristics increase the efficiency of data flow, reduce costs, monitor the true status of assets in real time, and ensure the trust of all parties in the transaction chain in the underlying assets.
Applications:
(1) Blockchain + Medical: In the medical field, blockchain can use its anonymity, decentralization and other characteristics to protect patient privacy. Electronic health records (EHR), DNA wallets, drug anti-counterfeiting, etc. are all possible application areas of blockchain technology. IBM predicted in last year's report that 56% of medical institutions around the world will invest in blockchain technology by 2020.
(2) Blockchain + Internet of Things: The Internet of Things is a very broad concept. If communications, energy management, supply chain management, sharing economy, etc. are included, the Internet of Things application of blockchain technology will has become a very important application field.
(3) Blockchain + IP Copyright & Culture and Entertainment: The Internet is developing better and better, and digital music, digital books, digital videos, digital games, etc. have gradually become mainstream. The rise of the knowledge economy has made intellectual property rights a core element of market competition. However, intellectual property infringement is serious in the current Internet ecosystem, and the copyright protection of digital assets has become a pain point in the industry. Blockchain features disintermediation, consensus mechanism, and non-tampering. Blockchain technology can effectively integrate all aspects of the cultural and entertainment value chain, accelerate circulation, and shorten the value creation cycle; at the same time, the value of digital content can be realized Transfer, and ensure that the transfer process is credible, auditable and transparent, effectively preventing piracy and other behaviors.
(4) Blockchain + Public Services & Education: In the fields of public services, education, charity and public welfare, issues such as file management, identity (qualification) certification, and public trust all exist objectively. The traditional method is to rely on A credible third party provides credit endorsement, but problems such as fraud and deficiencies still exist. Blockchain technology can ensure the integrity, permanence and unchangeability of all data, and thus can effectively solve the difficulties and pain points in these industries in terms of certificate storage, tracking, association, and backtracking.
