Learning Notes block chain V: Block chain 3.0 era
The world's major countries have begun around the block chain technology in key areas of networking, intelligent manufacturing, supply chain management, digital asset trading actively deploying applications. Our block chain technology has made in the application of financial, social governance in the field of digital some progress, with a good foundation, in close connection with the entity's economic development and social well-being such as to enhance the practical needs, and actively promote the chain block and the depth of integration of economic and social development, economic development and social progress to bring new impetus.
From the application point of view, the industry is generally divided into the development of the block chain block chain 1.0, 2.0 and 3.0 stage . 2008--2013 year block chain 1.0 stage, Bitcoin is a digital currency on behalf of the application, including the payment of that scene, the currency in circulation and other functions, in order to form Bitcoin economy and industrial ecology based. 2013 to Ethernet Square represented by block chain contract 2.0 applications add intelligence function that blocks the chain expanded from the original monetary system to equity, debt and registration, transfer of property rights trading securities and financial contracts, execution, even betting and anti-counterfeiting and other financial fields. Along with scalability and efficiency, Block Chaining range of applications beyond the financial scope will expand to the field of authentication, notaries, audit, domain name, logistics, healthcare, energy, visa, become a social protocol of the bottom of the Future , when the block chain will enter the 3.0 era.
" Block chain + supply chain " to achieve the whole process of product traceability information. Presence information opaque, the data can be manipulated, poor security, relatively closed other defects traceable security system traditional supply chain, and the use of the block chain technology and networking technology, information material procurement process, production process, distribution process of the product may be integration and traceability, real leap brands, distributors, retailers, consumers, fine to the whole process was a genuine dating back a yard, and a comprehensive display to the consumer through multiple online channels, significantly enhance the user experience of trust, for example, , block chain technology in agricultural production, detection, the flow of the whole process, the basic information for each bag of rice harvest time, processing time, location, etc. are recorded in the chain, in order to achieve tracking and tracing quality assurance.
" Block chain + cross-border payments " streamline processes to achieve cost efficiency. Cross-border money transfer business involves multi-country institutions, multi-national laws, regulations and exchange rate changes and many other issues, complex process, arrival long time, high cost, high cost and low efficiency has become one of the bottlenecks hindering the rapid development of cross-border payment services. Can be established by direct interaction between transnational payers and payees based on distributed intelligence sharing books with contract block chain technology, significantly simplifying the process flow, transaction information to achieve real-time sharing, real-time transaction settlement. Based on cross-border payments block chain can provide 24/7 service, reduce manual handling aspects of business processes, dramatically shorten the clearing and settlement time and weaken the role of intermediary in the transaction process by applying block chain technology, effectively reduce transaction direct and indirect costs in all sectors.
" Block chain + clearing and settlement " to enhance the level of openness and transparency. In the existing trading patterns, the inter-agency clearing and settlement must use third-party central clearing houses and infrastructure between different clearing houses, different business processes, resulting in clearing and settlement business links, processes cumbersome, inefficient and costly . Using a common digital currency block chain can achieve near real-time clearing and settlement based on point to point, can reduce intermediate processes, improve clearing and settlement efficiency. Intelligent contract block chain also enables automatic clearing and settlement of transactions based on, can save significant time and reduce labor costs. Based on system building block chain of disintermediation shared books can have all the clearing and settlement of all transactions recorded in the chain, both sides of the transaction transparent to be investigated, significantly improve the accuracy and efficiency of reconciliation. Since 2016, several domestic financial institutions have started reconciliation based inter-agency block chain technology platform that optimizes the reconciliation process between banks, while reducing reconciliation costs increased accuracy.
" Block chain + Intelligent Manufacturing " to create a safe and efficient intelligent manufacturing ecosystem. The traditional mode of production equipment operation and maintenance of records stored in the form of a single, reliability is not strong and other issues, the use of the block chain intelligence technology integration contract tandem design, manufacture, use, maintenance, important information intelligent manufacturing and service key aspects of recycling , executed by the smart trading contracts, spare parts and manufacturing units to achieve the full life cycle of track maintenance, strict protection of manufacturing processes and product quality, enhance the intrinsic quality of the manufacturing industry. Meanwhile, the block chain set up security, mutual trust and efficient bridge between global participants intelligent manufacturing ecosystem, provide low-cost, high-yield and privacy of communication for every participant intelligent manufacturing systems, and promote the participating efficient coordination between the parties. For example, a distributed intelligent production block chain project has been able to solve the industrial production of intelligent building contract, the value of the data transfer and trust issues.
" Block chain + of things" to build a network for information exchange Internet era everything. Distributed heterogeneous network block chain system is a typical P2P network, but things have distributed natural gene, each device in the network can manage its role in the interaction, behavior and rules to establish the block chain consensus mechanism of the system has an important supporting role. As the number of devices in the growth of things, such as managed in traditional centralized network model, it will bring a huge amount of data center construction and operation and maintenance investment. The distributed nature of the block chain of self-governance for the Internet of Things provides a way, things in the device can help to understand each other, and to understand the association between different devices, enabling distributed control of the Internet of Things.
" Block chain + health " to protect the security of medical data sharing. Block chain technology using mathematical encryption of medical data, medical data can effectively prevent malicious modification and other risks. Application of block chain technology development medical data sharing and exchange systems, medical encrypted data upload, data may be implemented in a patient, fast, efficient and secure communication between shared and various medical institutions, simplifies the medical data call flow, provide data protection for accurate diagnosis of the disease. For example, the company has developed a block chain platform for the treatment of chronic diseases, the regulatory agencies, medical institutions, third party service provider companies and patients themselves into the data sharing and alliance management chain, all parties in the protected ecological share sensitive information, coordinated implementation of integrated disease intervention mechanism is slow, make sure the disease has been effectively controlled.
