As of the end of 2019, my country’s blockchain technology The number of research institutions has reached 97. In addition, domestic universities have deployed blockchain technology research, strengthened the innovation of blockchain technology theoretical knowledge, and improved the blockchain technology research and development capabilities of universities. By the end of 2019, there were 24 universities in my country participating in strengthening blockchain technology research and development. The core technologies are mainly distributed in the aspects of consensus algorithm, cross-chain, underlying architecture and multi-chain.

Judging from the research results, in terms of consensus mechanism, my country’s consensus mechanism is gradually moving from a single algorithm to a hybrid consensus; in terms of cryptographic algorithms, cryptographic algorithms such as secure multi-party computation, homomorphic encryption, and zero-knowledge proof are continuously integrated and applied. ; Research on cross-chain technology and security technology has gradually become a research hotspot.

From the perspective of blockchain hardware, currently, the world’s most important digital currency mining equipment suppliers are all located in China, including Bitmain, Canaan, and Yibang Technology. Three mining equipment companies account for more than 90% of the market share.

From the perspective of industry applications, the financial industry is currently the industry with the most blockchain technology implementation projects and the richest scenarios, such as supply chain finance, asset certificate aromatization, credit reporting and risk control, etc.

China accounted for 60% of the world’s patent applications in 2019

With the tilt of national policies towards blockchain and the implementation of applications in various fields, blockchain-related patents have gradually been Attention from all parties. Compared with 2018, the number of blockchain-related patent applications from Chinese enterprises has increased significantly in 2019. Among the top 100 global companies on the list, my country accounts for 63%.

The blockchain industry will be further standardized in 2020

In 2020, my country’s blockchain policies will continue to be favorable, standards and regulations will be more perfect, industry scale will continue to grow, and technology will continue to innovate and develop. , the application demonstration effect in key areas is accelerating. At the same time, based on the problems existing in my country's blockchain development in 2019, CCID Blockchain Research Institute proposed to speed up top-level design and formulation, establish a sound regulatory system, accelerate core technology innovation and research and development, promote third-party evaluation and certification, strengthen professional talent training, and accelerate promotion Six suggestions for implementation in various fields.

⑵ What are the prospects of blockchain finance?

1. In fact, the combination of blockchain technology and finance is not accidental. Simply put, blockchain is a distributed shared ledger and database, which has the characteristics of decentralization, non-tampering, full traceability, and traceability. Finance is cooperation based on trust, and these characteristics of blockchain lay the foundation for creating trust. Blockchain technology is of great significance in solving problems in the financial field such as high credit risk, low capital utilization efficiency, and high payment processing costs.
2. In reality, Bitcoin is not equal to blockchain. Digital currency is just one of the applications of blockchain technology in the financial field. In the fields of supply chain finance, payment and settlement, trade finance, financial transactions, etc."Blockchain +" has rich application scenarios and imagination space.
3. Industry insiders point out that although blockchain technology has broad application prospects, there are currently only a few projects that have actually been implemented and produced social benefits. Blockchain technology is in its early development stage and still needs to be viewed rationally. In the next step, blockchain technology should be used to explore digital economic model innovation, add impetus to the optimization of the business environment, and provide support for promoting high-quality economic development.

⑷plus token, Leo, co-founder of PsEx: using blockchain technology to solve financing problems is the future trend

Sponsored by the Gangwon Province Government and the Korea Digital Currency Research Institute (KDC), The "Blockchain Pyeongchang Forum (BPF 2019)" co-organized by Golden Finance and others concluded successfully on January 30, 2019 at the Alpensia Convention and Exhibition Hall in Pyeongchang.

The forum, with the theme of "Smart Real Economy, Meet the Future of Blockchain", conducts in-depth discussions around global blockchain hotspots and exposes them to the world.Demonstrate the future possibilities of blockchain to the world. This forum also invited Governor Choi Moon-soon of Gangwon Province, South Korea, Speaker of the National Assembly Moon Hee-sang, Prime Minister of South Korea Lee Nak-yeon, President of the Korean Blockchain Association Woo Tae-hee, PsEx co-founder Leo, Blockchain Huang Chengyi, President of the Contents Association, Simon Cocking, Chief Editor of Irish Tech News and other world-renowned authorities participated in the conference forum.

In the future, PsEx will use its resources and experience in global operations to help physical enterprises in various countries go global, so that the global economy can achieve economic integration development better and faster with the support of blockchain.

⑸ 2018 is the first year of blockchain, so what is blockchain in 2019?

2019 is the first year of blockchain breaking financial monopoly
From Cable TV From companies to retail companies, all walks of life areStrive to preserve what they consider their most precious possession: their monopoly. The traditional view is: "If you control the entrance and the channel, then consumers have almost no choice."
However, we have seen companies like Netflix and Amazon break the original pattern and provide us with Life offers more choices. Likewise, in the world of digital currency and finance, some of the largest financial institutions are facing serious challenges.
It is expected that decentralized business and demand will rise in 2019, and I think this will provide more opportunities for already successful blockchain companies. At the same time, this opportunity also implies risks. If, as in 2018, blockchain company founders or entrepreneurs promise too much and the project is suspected of being exaggerated, they may be discredited and lose their first-mover advantage.
Asia was a step ahead
For decades, the world's largest financial institutions have controlled the vast majority of the global economy's financial system.
However, blockchain companies have begun to level the playing field by accessing banking services and real-time payments. In 2019, the blockchain industry will enter the field of securities, loans and other derivative financial products in addition to financial payments. Companies like Securitize*, Dharma, Dydx, Compound Finance and The Ocean are all companies dedicated to building decentralized finance.
In the past few years, mobile app companies such as RAP, Gojek and Paytm have expanded their business, with products such as payments, investments, remittances, loans and insurance. As many Asian economies shift from cash to a digital economy, they are rapidly attracting users of neobanks.
Asian regulators have provided clearer guidelines for blockchain and digital currency projects because they believe blockchain is a catalyst for economic growth and has the potential to become a sunrise industry in the future.
In addition, more than 80% of digital currency trading volume comes from Asia, so digital currency investors are very eager to build reliable infrastructure. If Grab, Gojek and Paytm can benefit from digital currency investors, then they will start to support blockchain more and provide a better experience for payments, loans and other derivative financial products.
Back to Original Intentions
Over the past few years, the digital currency industry has strayed away from its original financial vision, and this was well illustrated in Satoshi Nakamoto’s Bitcoin white paper. Just like the boom and bust of the Internet, almost every real-life case imaginable, such as tracking the freshness of flowers and other logistics chains, are using the buzzword blockchain to attract attention.
However, just like the early Internet, real implementation cases must match the development stage of the technology.
For example, Netflix would not have been able to successfully stream TV shows in 2000, when less than 1% of the population had access to broadband. In the past few years,It is becoming increasingly clear that payments are a real-world example of blockchain now being used at scale.
In 2019, blockchain companies will build on this foundation and use smart contract platforms to rapidly develop in decentralized financial applications (such as loans and insurance products).
I always find that the best applications happen in specific market segments. As long as blockchain companies can focus on products that solve specific problems, then we will see more competitive products. , innovative blockchain companies.
And, this is a good thing for the entire industry.

⑹ What are the practical applications of blockchain technology in recent years?

The blockchain financial field is the most widely used

The main distribution of blockchain industry applications in my country In finance, supply chain, traceability and hardware, accounting for nearly 65%. According to the "Blockchain Blue Book: China Blockchain Development Report (2019)", there are nearly 28,000 blockchain companies in the country. Among them, about 1,000 blockchain companies have been put into production, accounting for only 3.6%. They are mainly concentrated in developed eastern regions such as Beijing, Shanghai, Guangdong, and Zhejiang.

——For more data and analysis, please refer to the "Forward-looking Industry Research Institute" China Blockchain Industry Market Prospects and Investment Strategic Planning Analysis Report".

⑺ What disruptions does blockchain bring and why can it become a national strategy?

The disruptive characteristics of blockchain lie in the following four aspects: 1. Transparency. The data records of the blockchain system are transparent to the entire network nodes, and the update operations of the data records are also transparent to the entire network nodes. This is the basis for the trust of the blockchain system. Since the blockchain system uses open source programs, open rules and high participation, blockchain data records and operating rules can be reviewed and traced by nodes throughout the network, with high transparency.
2. Openness. The blockchain system is open. Except for the private information of the parties directly related to the data, which is always encrypted, the blockchain data is open to everyone (except for blockchain systems with special permission requirements). Anyone or participating nodes can query blockchain data records or develop related applications through the public interface, so the entire system information is highly transparent.
3. Information cannot be tampered with. Once the information of the blockchain system is verified and added to the blockchain, it will be permanently stored and cannot be changed (except for systems such as private blockchains with special change requirements). Unless more than 51% of the nodes in the system can be controlled at the same time, modifications to the database on a single node are invalid, so the data stability and reliability of the blockchain are extremely high
4. Decentralization. Decentralization is the most basic feature of blockchain, which means that blockchain no longer relies on central processing nodes and realizes distributed recording, storage and updating of data. In a traditional centralized network, attacking a central node can destroy the entire system, but in a decentralized blockchain network, attacking a single nodePoints cannot control or destroy the entire network. Mastering more than 5% of the nodes in the network is just the beginning of gaining control. 2019 is the first year of commercial application of blockchain technology, and favorable policy incentives will make the development of blockchain technology more stable.
As the application of blockchain technology gradually penetrates into many fields such as digital finance and the Internet, everyone has a clearer understanding of the value of blockchain.
Blockchain has formed a global competition situation. All countries are seizing development opportunities, and China cannot lag behind; therefore, it is understandable that blockchain has become a national strategy.

⑻ What are the applications of blockchain in 2019

The applications of blockchain in 2019 are: Triporg is a blockchain + travel service platform that can provide bookings for air tickets, train tickets, etc. Serve.

⑼ Breaking 100 million in 6 months! Zhejiang Provincial Department of Finance and Ant Blockchain bid farewell to paper tickets

Zhejiang Online, January 15 (Zhejiang Online Correspondent Chen Jieqiong) In order to better solve the "run once problem", local governments are increasingly applying new technologies. Coming faster and faster. Recently, Ye Shibao, director of the Electronic Invoice Center of the Zhejiang Provincial Department of Finance, said in an interview that since the establishment of the provincial blockchain electronic invoice platform in June last year with Ant Blockchain, as of the end of 2019, 507 medical institutions in Zhejiang Province have been on the blockchain. , 74 public hospitals realized electronic bill reimbursement in other places within the province, 100 million fewer bills were issued, and more than 30 million bill printing costs were saved, once again at the forefront of innovation.

Interestingly, electronic bills have been promoted for many years but there are still many links that cannot be solved. Blockchain has become a key. It is understood that Ant Financial is the first company to explore the application of blockchain technology in digital government industries such as finance and taxation. Through Ant blockchain technology, electronic bills can be "stamped" throughout the entire process from generation, transmission, storage to use. The entire process is traceable and cannot be tampered with, ensuring that the authenticity of the bill can be quickly confirmed in every circulation link, thus Achieve cross-regional and cross-department settlement and reimbursement.

Ye Shibao said that according to previous statistics, the entire process used to take about 12 working days to go to the medical insurance department for reimbursement, while commercial insurance reimbursement took longer, taking 7-60 working days. Now you no longer need to hold the ticket and stamp it in several places, you can quickly receive it with just a few clicks on your mobile phone.

Zhejiang University Shaw Hospital is one of the first hospitals in the province to go online. For Zhao Yue, a bill administrator who has worked in the finance department for 30 years, this is also a good thing.

In the past, he manually reviewed half-meter-high stacks of receipt stubs every day, and packed a large box every eight days on average. The pile could not fit in the office, and he would ask his colleagues to move it to the warehouse for storage. After receiving it and then doing the write-off, "it will take several months to complete the entire process." Nowadays, fewer and fewer bill stubs are collected every day, from the original half meter high to ten or twenty. "The warehouse is no longer needed, and several vehicles that transport the bills for destruction have also been returned."

The whole chain of hospital electronic bills and reimbursement claimsThe road opening will ultimately improve the "last mile" experience of patients seeking medical treatment. Taizhou Hospital dared to be the first to allow Mr. Pang, a local resident, to receive reimbursement without traveling for 7 hours at a time when he was on a business trip to Hangzhou for medical treatment. He became the first person in the country to realize the reimbursement of medical insurance in other places through blockchain electronic bills.

The changes in each hospital are just the tip of the iceberg. Subway ticket settlement on the chain allows users to pass with one code, Hangzhou Internet Court introduced the Ant blockchain, provident fund withdrawal, etc. Zhejiang Province has completed implementation in more than 26 fields. From mobile payment to digital economy, Zhejiang has always been ahead of the curve in the application of innovative technologies.

At the 2020 Zhejiang Two Sessions held recently, Jing Xiandong, a member of the Zhejiang Provincial Committee of the Chinese People’s Political Consultative Conference and chairman of Ant Financial, said that he will continue to use AI and blockchain to promote the upgrading of Zhejiang’s digital government affairs and promote Zhejiang to become a national Digital government model province. In the future, only applications that benefit the real economy and the public will be truly valuable applications, and blockchain must fundamentally move away from virtuality and into reality.

⑽ What is the recent development of blockchain? Are there any formal projects to introduce?

Analysis of the expenditure scale and application prospects of China’s blockchain industry in 2018 will be close to US$300 million in 2019. Solve shortcomings and promote economic development

Blockchain technology is expected to be widely used in the economic field

Blockchain technology is important for cultivating new drivers of economic growth, building an honest society, improving the level of management technology, and easing the pressure on small and medium-sized enterprises. Financing difficulties have strong practical significance and are expected to be widely used in the economic field. At present, the application of blockchain technology is still in the early stage of development and faces many challenges. We must actively promote the application of blockchain in multiple fields, scenarios and environments of the economy and society, create a good industrial development environment, improve the quality of development, and strengthen Blockchain core technology research and development, professional application demonstration, strengthening standard manufacturing, talent training and the construction of public service platforms.

China’s blockchain market spending in 2019 will be close to US$300 million

According to the “In-depth Analysis Report on Business Model Innovation and Investment Opportunities in China’s Blockchain Industry” released by the Qianzhan Industry Research Institute 》Statistics show that as of 2017, China’s blockchain market expenditure was only US$83 million. In 2018, China’s blockchain market expenditure will reach US$160 million. It is also predicted that China’s blockchain market spending will be close to US$300 million in 2019. At this stage, the overall market size of blockchain is small. This is because most of the blockchain projects on the market are in the experimental stage and the investment is not large. On the other hand, many companies have realized the potential of blockchain and plan to increase their budgets in the future. Affected by this, China's blockchain market will usher in rapid growth, with market expenditures expected to reach US$1.95 billion in 2023. The average annual compound growth rate from 2019 to 2023 is 60.51%.

Statistics and forecasts of China’s blockchain market expenditure from 2017 to 2023

MediumAnalysis of unfavorable factors for the development of blockchain in China

1. The technology is not mature enough. At present, blockchain technology is not yet mature in terms of system stability, application security, and business models, and cannot meet the requirements of "high efficiency and low energy", "decentralization" and "security" at the same time. First, performance issues. The transaction throughput that can be carried out on the blockchain is not high, and the current block capacity is very small, which leads to network congestion and high-frequency business needs are difficult to meet. Many projects are also working on optimization, but they are far from real scenarios such as banks. There is still a certain distance between the transaction throughput of , stock exchanges, etc. Second, there is the issue of consensus mechanism. In terms of energy consumption, consensus algorithms such as workload proof consume a lot of energy and cost, causing the blockchain to waste a lot of computing power and matching power across the entire network. In terms of types, the current blockchain consensus mechanisms are too few in type and will be diversified in the future. In business scenarios, a richer consensus mechanism is inevitably needed to adapt. Third, security issues. Issues such as privacy protection, harmful information on-chain, smart contract vulnerabilities, consensus mechanism and private key protection, computing power attacks, cryptographic algorithm security, etc. all make the blockchain face a severe situation of platform security and application security. Fourth, database issues. Unlike traditional databases, blockchain applications require a large number of write operations, HASH calculations, and verification operations. Database systems specifically for blockchain are still difficult to overcome.

2. The application scenario is unclear

Currently, the blockchain project is still in the exploratory stage, and no specific implementation scenario can be found. At present, promising areas include finance, sharing economy, Internet of Things, public services, etc. However, judging from the maturity of existing blockchain technology, there are still many problems in blockchain applications, and there is still a gap between actual use. First, the immaturity of blockchain technology has restricted commercial applications. Although there are currently many types of core blockchain technologies such as privacy protection algorithms and consensus mechanisms, they are generally not commercially available. Secondly, the application model of blockchain is still being explored, and the "irreplaceable" advantages of blockchain have not yet been realized. The blockchain itself represents a consensus system, and a consensus system that conforms to the corresponding business scenario should be built from a higher level, not just "business + blockchain". China has a large number of users, complex business scenarios, and any commercial product will involve a very large traffic and population, and the current blockchain technology cannot satisfy it.

3. Scarcity of professional talents

Blockchain technology is a multi-disciplinary and cross-field technology, which mainly involves operating systems, network communications, cryptography, mathematics, and finance. , production, etc., but currently our country still has shortcomings in interdisciplinary fields and fields, and the supply of talents in related fields is seriously insufficient. On the one hand, there is a huge gap in R&D technical talents. Blockchain technology research and development mainly focuses on programming languages ​​​​such as Go, Javascript, C and C+, and new smart contracts use new functional programming languages ​​​​such as Haskell, Ocaml, and Rholang. In China's talent market, there is a huge shortage of technical talents with senior R&D experience in relevant languages.mouth. On the other hand, there is a lack of design talent at the bottom level. Different from R&D technical talents, blockchain underlying system architecture design talents must master multiple cross-disciplinary professional skills. They must not only have an in-depth understanding of the underlying design principles of blockchain and have experience in the design of various system architectures, but also master the business logic of specific application scenarios. . Although some colleges and universities have launched cross-disciplinary education and blockchain-specific technical disciplines, professional talents are still very scarce.

Analysis of favorable factors for the development of China’s blockchain

1. Favorable policies promote development. In January 2017, the Ministry of Industry and Information Technology released the "Software and Information Technology Service Industry Development Plan (2016-2020)", which proposed requirements for innovation in blockchain and other fields to reach international advanced levels. In August 2017, the State Council issued the "Guiding Opinions on Further Expanding and Upgrading Information Consumption to Continuously Release the Potential of Domestic Demand" and proposed to carry out pilot applications based on new technologies such as blockchain and artificial intelligence. In October 2017, the State Council issued the "Guiding Opinions on Actively Promoting Supply Chain Innovation and Application" proposing to study and use emerging technologies such as blockchain and artificial intelligence to establish a credit evaluation mechanism based on the supply chain.

In March 2018, the Ministry of Industry and Information Technology released the "Key Points of the Standardization Work of the Informatization and Software Service Industry in 2018", proposing to promote the establishment of the National Informatization and Industrialization Integrated Management Standardization Technical Committee, the National Blockchain and Distributed Records Accounting Technology Standardization Committee. In June 2018, the Ministry of Industry and Information Technology issued the "Industrial Internet Development Action Plan (2018-2020)" to encourage and promote the application research of emerging cutting-edge technologies such as edge computing, deep learning, and blockchain in the Industrial Internet.

Since blockchain was first included in the "13th Five-Year Plan" National Informatization Plan in 2016, blockchain has increasingly received attention and attention from the national government. Beijing, Shanghai, Guangdong, Hebei, Twenty-four provinces, cities or regions including Jiangsu, Shandong, Guizhou, Gansu and Hainan have launched dividend policies, carried out the layout of the blockchain industry chain, and actively explored industry applications based on blockchain.

2. The blockchain industry is gradually taking shape

At present, my country’s blockchain technology continues to innovate, and the blockchain industry is gradually taking shape, starting in supply chain finance, credit reporting, and product traceability. , copyright transactions, digital identity, electronic evidence and other fields are expected to promote technological changes, organizational changes and efficiency changes in our country's economic system, making important contributions to building a modern economic system. With the continuous influx of entrepreneurs and capital, the number of enterprises has increased rapidly. Blockchain applications will be implemented faster, boosting the high-quality development of traditional industries, accelerating industrial transformation and upgrading, using blockchain technology to "reduce costs" and "increase efficiency" for the real economy, and promote the standardized development of traditional industries. In addition, blockchain technology is deriving into new business formats and becoming a new driving force for economic development. Blockchain technology is promoting a new round of business model changes and becoming an important support for building an honest social system.

3. Broad application prospects in the future

In the past, it was difficult to trace the circulation of physical banknotesYes, but with the application of blockchain technology, the flow of all digital assets will be traceable. For example, in the financial field, blockchain is expected to solve the pain points and difficulties in the payment field, reduce the complexity of transactions, increase the end-to-end speed of transactions, reduce communication costs in the transaction process, and improve the transparency and non-tamperability of transaction records. The cost of reconciliation, clearing, and settlement between financial institutions, especially cross-border financial institutions, has always been high, and there are complex manual processes. Blockchain technology has data that cannot be tampered with and is traceable, and its application can help reduce financial costs. The cost of reconciliation and dispute resolution between institutions can significantly improve the processing speed and efficiency of payment business, and also make small-amount cross-border payments possible. In addition, the application of blockchain will also extend to many fields such as medical health, education, charity, social management, etc. The market prospects are very broad.
