As a decentralized distributed ledger database, blockchain can make the generation, operation and application of data more open and transparent. Under the condition of market economy, data is information and economic value; Real and transparent data has higher economic value and is easier to be applied in business scenarios. In the process of data collection, storage and application based on blockchain technology, data information can not be tampered with and can be traced back, which can make the market allocate resources more effectively. Therefore, the blockchain is considered to be another great innovation after the Internet, and it is the arrival of the second Internet era-the value Internet era. Blockchain will bring great opportunities for change to all walks of life from the infrastructure level.
In the research and application of blockchain, China has both market base and technical advantages. Now, the blockchain has been promoted to the height of national strategy and has become a new outlet for a new round of scientific and technological revolution and innovation. On the last day of 2020, let's look forward to 202 1. In the new year, what aspects of blockchain technology application are most worth looking forward to?
1. Security traceability has become the basic application of blockchain.
The core concept of blockchain technology, openness, credibility, decentralization and enjoyment, is widely recognized by everyone. As the key direction of blockchain technology application in recent years, security traceability has played an important role. In 2020, a series of applications such as Anhua black tea safety traceability, Guizhou ancient tea tree safety traceability and Guizhou Moutai safety traceability have been realized, and good application results have been achieved.
Tracing back to the source is an act of tracing back to the source, which usually refers to obtaining key data of commodities or information by various means of collection and retention during the production, circulation and transmission of commodities or information, such as the starting point, node and end point of circulation and transmission, data category, data details, data collector and data collection time. And store data in a certain format and way in a certain way. Forward, reverse and directional query of stored relevant data, and trace the source of articles and information.
Traceability can realize 100% bidirectional traceability of all batches of products from raw materials to finished products and from finished products to raw materials. After the establishment of the traceability system, once relevant accidents occur, supervisors can judge whether there is negligence in a certain link through the system, and can also use the system to find out which link, which step went wrong and whose responsibility it is, so as to avoid the difficulties caused by incomplete information and unclear responsibilities and solve the problem faster.
Second, the blockchain completely solves the problem of copyright protection from the technical point of view.
The mathematical principle of blockchain technology solves the problem of ownership confirmation in the transaction process, and the recording, transmission and storage results of value exchange activities are credible, which can completely solve the problem of copyright protection. On the "Where to Go Fishing" platform, we will protect the copyright of all video works shared by Yule through uploading.
Third, distributed storage will become the largest application of blockchain in the world.
Compared with traditional centralized storage, distributed storage has many advantages, which will surely become the future technology development trend.
There are many distributed storage technologies, among which IPFS (Interstellar File System) is the best. The goal of IPFS is to create a persistent distributed network transmission protocol for storing and sharing files. It is a peer-to-peer hypermedia distribution protocol with addressable content. IPFS protocol uses the advantages of blockchain protocol and network infrastructure to store unchangeable data, delete duplicate files on the network, and obtain address information of storage nodes-searching files in the network.
IPFS is considered to be likely to replace HTTP protocol in the future. The information released by IPFS will not suddenly disappear in the emergency of service providers or managed networks, and the security will be improved. IPFS has no central distribution system and is very fast. The advantages of IPFS can just solve the problems of traditional centralized cloud storage, such as easy data leakage, easy hardware damage, weak repair ability, low security and the risk of operation termination at any time. Through the underlying protocol of IPFS, distributed storage copies the database into multiple copies to ensure redundancy, and then divides it into several small parts and stores it on many nodes of the network, so as long as there are enough nodes running normally, the data is safe.
Although blockchain is only an optional part of IPFS, it is blockchain technology that promotes the rapid landing of IPFS. We have provided a complete set of solutions for IPFS applications, and are building a rich application ecosystem based on IPFS to accelerate the development of distributed storage applications.
Fourth, the application of blockchain and edge computing, Internet of Things, artificial intelligence, 5G and other technologies brings greater value.
The combination of Internet of Things, 5G, artificial intelligence, edge computing and other related technologies with blockchain will bring greater value to network participants. Blockchain data is more credible and will better provide and enhance the underlying algorithm. Blockchain will help to ensure the security of data and audit every step in the decision-making process, thus making the insight of network participants more acute.
A project that we are jointly carrying out with Hunan Mobile Company is to give full play to the edge computing capability of cloud computing technology based on blockchain technology for 5G application scenarios, and build a distributed cloud computing and cloud storage platform on the edge infrastructure. An elastic cloud platform with comprehensive capabilities of computing, network, storage and security is formed at the edge, and an end-to-end technical architecture of "cloud-edge three-body collaboration" is formed with the central cloud and IOT terminals. By putting the work of network forwarding, storage, calculation and intelligent data analysis on the edge, the response delay, cloud pressure and bandwidth cost are reduced, and cloud services such as network scheduling, computing power allocation and distributed storage are provided. Blockchain technology has natural advantages in trust, knowledge and value transfer, and will provide a powerful technical means for cloud node big data to provide data confirmation, value discovery and data governance.
5. The financial sector will remain the best field for blockchain application.
At present, the application of blockchain in the financial field is the best, and related technologies are also developing the fastest; In the future, finance will still be the best field for blockchain applications. Blockchain is a systematic solution for financial institutions to address the pain points and chronic diseases in the entire business chain. Its "systematicness" is mainly reflected in three aspects: blockchain technology can be applied to different banking businesses, from payment and settlement, to bill circulation and supply chain finance, to more complex core business areas such as securities issuance and trading, and financial institutions and technology companies are actively exploring and trying. The benefits brought by blockchain technology will benefit all transaction participants, including banks, bank customers and bank partners. At present, most of the pain points such as efficiency bottleneck, transaction delay, fraud and operational risk in various processes of financial services are expected to be solved after the application of blockchain technology. For example, a large number of manual operations, manual audits and approvals in the existing processes will be automated, paper contracts will be replaced by smart contracts, and losses caused by system errors will no longer occur in transaction processing.
We are also actively exploring cooperation with Hunan Construction Bank, relying on the tea industry blockchain platform to provide supply chain financial services for Anhua black tea enterprises.
6. There will be more and more blockchain applications for collaboration and management.
Blockchain ensures the digitalization and real-time sharing of all information, thus improving the cooperation efficiency, reducing the communication cost, and allowing multi-party entities with high degree of dispersion, long management chain and many links to still cooperate effectively.
Our "Wenzhou Logistics Platform Based on Blockchain" has become the first intelligent logistics platform based on Internet of Things and blockchain technology in China. Among them, according to the terms of the contract, the intelligent contract automatically executes instructions such as contract signing, transaction conclusion, expense settlement, electronic reconciliation, invoice issuance and collection; IoT devices realize the visualization of operational data, and the whole business process is open, transparent, safe and credible; The unique banking technology of blockchain solves the financial support and is more efficient and convenient than the traditional online banking transfer mode; Decentralized service evaluation recorded in the public ledger makes users' credit digital and capitalized, and provides credit evaluation for bank insurance to carry out financial services such as loans and factoring.
In such a credible freight logistics ecology, shippers have realized transparent and safe data management, drivers can get timely supply orders, optimized logistics routes and reliable cargo protection, while logistics platforms can focus on providing capacity matching and establishing a * * * contract awareness mechanism, so that the entire supply chain can effectively organize high-quality long-tail logistics resources and coordinate and meet the interests of all parties involved in the alliance.
7. Digital RMB will become the key driving force for the digital transformation of the industry, and "asset entanglement" will become the general trend.
All industries deserve to do it again through the "blockchain+"approach. Digital RMB, which has been applied in pilot projects, is not only a payment channel, but also a key tool for digital transformation of enterprises. The operation and management methods of enterprises will be fundamentally changed, and a new intelligent commercial times has arrived. We should actively promote the innovative application of intelligent technology integration and accelerate the promotion of more enterprises' "winding" related applications.
We are docking with a number of banking institutions to enrich the application scenarios of digital currency, the People's Bank of China, and make technical docking in advance for the landing of digital currency, the central bank.
8. The relationship between blockchain and digital currency will be further rationalized.
Although people's understanding of blockchain is becoming more and more rational and objective, digital currency has always been an unavoidable hurdle. So we see many applications of blockchain, although they all focus on application, but in the process of application, people always naturally associate landing and application with digital currency. When the development of blockchain industry enters a new stage, one of the keys is to straighten out the relationship between blockchain and digital currency.
Digital currency and blockchain are not incompatible, but can promote each other. The chaos we saw in digital currency in the early days was mainly because people only regarded digital currency as the only blockchain. Digital currency should now be used as the key to open the closed loop of blockchain scenario application.
When the blockchain and digital currency are at the same potential energy and cannot establish a healthy relationship, the development of blockchain will fall into a strange circle. It is the key to ensure the sustainable development of blockchain technology to truly regard digital currency as the key link to open up the application scenario of blockchain and straighten out the relationship between private chain digital currency and public chain digital currency, especially legal digital currency.
9. Blockchain will be widely deployed and become an important support for building a digital China.
With the continuous development of blockchain technology in China and the continuous expansion of blockchain application fields, the blockchain industry in China will present the blockchain as the frontier of global technology development and open up a new track for future international competition; The blockchain field has become a new hot spot for innovation and entrepreneurship, and technology integration will expand new application space; Blockchain will be widely used in the real economy in the future and become an important support for the construction of digital China; Blockchain creates a new platform economy and opens a new era of economic enjoyment; Blockchain accelerates the process of "trusted digitalization", drives finance "from virtual to real" and serves the real economy; The blockchain supervision and standard system will be further improved.
20 19, 10, the blockchain officially rose to the national strategic height; In April 2020, the National Development and Reform Commission listed the "blockchain" in the scope of new infrastructure for the first time, and made it clear that it belongs to the new technology infrastructure of the new infrastructure information infrastructure. This brings opportunities to the blockchain market of 202 1, and also makes the blockchain full of power and vitality in technology development and industrial application.
The state calls on us to take blockchain as an important breakthrough for independent innovation of core technologies, clarify the main direction, increase investment, focus on tackling a number of key core technologies, and accelerate the development of blockchain technology and industrial innovation. We firmly believe that the integrated application of blockchain technology will play an increasingly important role in new technological innovation and industrial transformation, and 202 1 is the most anticipated key year.
